Elsewhere in these comments, it is said that ""people put these in those 4wd Tercel wagons." That's true, I did it, but it is harder than you think. A 4age block will bolt right to the tercel trans, but there are other problems. The accessories are one..the different head and timing belt cover were a factor. Not too bad, though. The cooling system is a bit weird if your donor car is an mr2 (like mine), especially if using the larger mr2 radiator. The starter ended up being an mr2/Tercel hybrid, out of necessity. The tercel flywheel will not fit the 4ag crank (8 bolts vs 6) and the mr2 ring gear will not go in the tercel trans. I turned down the 4ag flywheel to accept the smaller ring gear. Used part of a bad 4ag crank as a mandrel. You must remove the ring gear from a tercel flywheel intact. They aren't sold separately. Now the mr2 clutch won't fit in the tercel trans. Almost, though. Grind/cut inside of bellhousing, it works. Fortunately, the input shaft splines match the mr2 disc. The tercel clutch cable interferes with the mr2 exhaust (now on the left). Tried many cables, I think the one that worked was from an old accord or prelude. I made a manifold, and ran it on gsxr-1100 carbs. Got them to work beautifully, like EFI. It even got good mileage. However, they are on the small side for a 1600 motor, and despite looking cool, it limited power at high rpm. The ignition used with the carbs was MSD with timing controls, as there was no ECU at this time. I then put the mr2 EFI on it. The manifold didn't fit under the hood...cut & weld that. The tercel fuel pump was engine driven, and low (carb) pressure. So..weld ring into tercel fuel tank and fab bracket for that, to use the stock mr2 pump. Make fuel lines. The throttle body points at the firewall now, requiring some ingenuity to connect it nicely to a large air filter.. The exhaust comes out the wrong side. Making a complete 2 1/4" exhaust for this was actually pretty hard..the unibody had room for a small exhaust only on the right side. The trans input shaft for the Tercel has a thin area, looks weak, but did not break, and I was abusive to it. The trans gear ratios were not well suited to the 4ag..you better rev it to 7500+/- rpm, or ot drops "off the cam" for a moment after an upshot. This made it either sort of slow, or moderately fast if you "whup on it". I estimated than mine may have been 150 hp, maybe. Wiseco pistons, head work, high compression, nice intake/exhaust. Stock cams. This did not make for a real fast car after a LOT of work- almost as a direct result of this, I now have an LS2 in a volvo wagon....I highly recommend this. 400 plus torquey, reliable hp..it's a blast. I think the volvo v8 swap was easier, and I made everything..engine & trans mounts, exhaust, driveshafts, etc. I have seen others who have claimed to do the 4AG tercel thing, but their pics showed only a long block in the car, clearly not running. Please comment if you have, or have seen another one. Definitely not as easy as it first appeared, I was tricked by the in-common "A" family engine. I drove it thousands of miles this way, my main car for a few years. Still have it, haven't run it for 10 yrs. It is red like Jesse Pinkman's of Breaking Bad. Haha maybe it's valuable! It is unique.

[@_jake70]

Nice video, lots of great info here. I would like to add that the issue with oil pumps themselves are in the early gen pumps with square edged gears, later pumps (silvertop 20v is considered the better option) are great off the shelf for majority of builds. The problem with breaking gears on the bigports pertains to oil Cavitation. The head only has an oil return in the centre of the head on the exhaust side. Under high rpm and cornering forces, oil tends to get trapped in the head for a little too long which effects the pickup volume at the sump. The smallport engine has addressed this with an additional oil drain from the rear of the head down to the block amongst other efficiency upgrades. The bigport has the provisions for these drain ports to be machined for fittings by a skilled tech.

[@motoiq]

We restrict the oil flow to the head down to about 2mm. This lubricates the valvetrain fine but prevents pumping all the oil to the top.

[@zerohikari2685]

A lot of misinformation here. Stock 2nd Revision crank is good to 10,000 RPM and well above 220 NA WHP. You never need to upgrade the crank it is already forged. You only need to upgrade the crank for above 10K. Please check Garage4age for examples. The stock 20v engines already rev past 8,000 RPM stock so any talk of 8,000 being the limit is pure ignorance. My stock bottom end ST using BT electronics revs to 8,400 RPM track driving bouncing of the limiter and has no issues. The issue with reving to 9000 RPM and above are two things. You need stronger rods and you need a 3rd revision oil pump or toda gear. Everything else will hold up fine until you cross 9,500 RPM. The issues the the crank journals flexing only happens when you near 10K. And Formula Atlantic engines use ported Small port engines not big ports. Big ports are rarely used outside of forced indunction builds.

[@LANTICA]

True true on all things I've read and heard reported over the 10+ years of me being into 4ags.. Including the use of small port heads on Atlantics

[@motoiq]

The large journal OEM cranks aren't good to 10k rpm at that power level or at least not for long, it's not like you can routinely rev to 10k either, you are probably talking about people who do this on the street or have low power engines. I am talking about engines that can handle track days with power in the over 200 whp range. I mean we built a an engine with a lash up of the best OEM parts for a local drift school that takes 9k rpm all day but its in stock form with stock cams but set up shim under bucket, head, etc. The worst issue about reving past 9k rpm isn't just the rods, The block itself lacks structural integrity and the main cap registers get chewed up and the caps walk. Then the bearings get chewed up. The crank fails at journal #3 even large journal billet ones. For a track-driven car in the 230 whp range, the rod bearings last about 3 hours and the crank 9 hours. To maintain reliability, they have to be switched out at that point. This is at 9200 rpm not 10,000. Our experience is I was an engineer for TRD and did stuff for GT3 and Formula Atlantic and Howard was one of the senior tech's and built and maintained scores of Atlantic motors. So we have plenty of experience about what you can get away with on these engines. If you don't believe me, ask anyone involved with Pro Atlantic or GT3 racing at the time or someone who drifts these at a high level, these engines were pretty maintenance intensive to be reliable. Maybe the later variants of the Atlantic engines used small ports but while I worked at TRD they were all large ports. Most of the gains of those year engines was major porting on the exhaust side of the engine. Nowadays you have better engine control and better bearings but the majority of grassroots people may not have this. Also tuning quality is a big variability. Later versions of the Atlantic motors had really beefy dry sump pans and valve covers which actually stiffened the engine considerably and allowed higher revs but that was after my time. motoiq.com/this-old-picture/ Here is a picture of us in the hot pits at the SCCA Runoffs at Road Atlanta in 1985 with one of the Toyota factory AE86 entries. That's me with the black TRD jacket and TRD shirt with the cool shades. Howard is messing around with something on the right front wheel.

[@zerohikari2685]

@@motoiq @MotoIQ I race this engine now, not 35 years ago so do scores of other people and we have thousands of hours of testing on track with dyno numbers. I specifically have experience with endurance racing the 4age and oil starvation in cylinder 4 is the only issue we had running an entire year of enduro with a Silver Top and we fixed it eventually. The caps did not walk. You can go to 9K on a 7rib if your clearances are correct. Saying bearings last 3 hours is beyond ridiculous as well. Any Atlantic engine built by Hasselgren Lyonings or any builder worth it's salt will last at minimum 100 hours or 3 seasons. Why? Oiling, I guarantee all these issues you think are block and crank related are simply oiling related you had are oiling related. People run 670 whp on stock 7afe cranks and you know what breaks first? The flywheel bolts. It's all been addressed in the last 20+ years. If what you are saying was true my MR2 should have bearing all over my oil pan yet the car has had 20+ track days slamming up to 8,400 RPM and we don't have any sparkles in our oil. Just go watch Garage4age's videos. He's puts all the rumors to rest the past few years and you can watch his small port rev again and again and again to 10K on a stock crank and block.

[@motoiq]

There is no way a fully modified 4ag at decent power levels that is actually raced will go 100 racing hours and 3 seasons between refreshes unless it is in near stock condition and probably not even then, in fact, no racing engine will go that long. Heck even limited mod class modern engines don't last that long. Remember we worked with Hasselgren and Lyonings extensively during the Toyota Atlantic era they are not magical builders with 4AG secret sauce. The block issues are not oiling-related the evidence left behind is very different. We were running dry sumps so it is not oiling. So maybe your engine isn't putting out much power and is equivalent to what we did for rally motors which still didn't last anywhere near 100 hours. But for real edge of power output for the VE this engine is capable of, this is actually what will happen to the engine. The bearings were not ruined at 3 hours nor were the cranks at 9, they were changed at these intervals as PM or the engines would experience major failure if you didn't. The bearings did show signs of load wear at this interval at 9 the cranks had a good chance of failing mag. You can have your opinion but this is what we experienced as a factory works team developing the engines. You have youtubers doing things, I am not taking away from anything the best of them do, but are they professional engine builders competing in and supporting a series? I mean sure we could do a clickbait title and build a 10,000 rpm motor inexpensively but I am not sure I would want to sell one to a customer.

If you haven't broken your stock parts, you are probably driving on the street or something, run on an actual road course and wind it to 9k for a whole track weekend and see what happens. We built an engine for the local drift school using a lashup of all the best stock parts and it sees 9k rpm all the time but it is completely stock and makes something like 77 whp on our dyno. If it was hotted up it would not live very long. Ask anyone who raced these in FA or GT3 and they can tell you how weak and finicky these engines are even with the best parts. I have no doubt that you can run them hard in drag racing with some of the new parts like bottom end girdles and tall deck blocks, that's only for a few seconds at a time. The MRP guys also get 1000 hp out of Drag 4AG's. Hey if you don't break your car with the type of driving you do, more power to you but it doesnt mean I don't know what I am talking about or this video has bad information. What I said isnt even secret, its stuff all the successful builders of 4AG's do.

Well my experience with this engines are not bad at all.. driving it 10years with noy one time it broke.. i have a drysump on.. no reinforcements, std crank 42mm jurnal off centred grinded to fit the s2 rods and the small jurnal of the rod from 18mm to 20mm so gained stroke.. 0.50 over size piston but toyota pistons not even forged.. head is a s3 big port with std valve.. only aftermarket i have is cams and arp conrod bolts.. thats it.. and have slide injection on it and alliflywheel and electric waterpump... makes 200whp on yhe front wheels witj 189nm and its 10years alive.. and driving it like a boss everytime. Yes its a street car.. we builded a racing car and the same lasted 5years on the track.. before retired it.. and still have 7 track records in the 1600cc class.. im not questioning your experience but these little engines are tough as hell in SA with miner works..

[@motoiq]

The drysump makes a huge difference in parts life on these engines but not too many people can afford it. Your build is pretty interesting, we did something similar to build a cheater ITA class motor, the internals had to look stock, and it ran for several seasons but it had nowhere near the power of yours, something like 180 hp.

The MR2 3S-GTE would be great too for a video. Everybody talks about 4AGE or 2JZ, and very little about 3SGTE. I'm currently building a gen2 3sgte for my 92 MR2 and there's not a lot of information and choice when it comes to choose component.

[@scareyaf]

Awesome, informative video as usual. Wondering how the 7AFE block compares to the 4AGE? I may be wrong but I'm sure Tsuchiya runs a 7A block.

[@motoiq]

Taller deck, so room for 90mm stroke and a decently long rod for a resonable rod ratio.

[@Videoswithsoarin]

if its a 7A block its likely a 7AGE hybrid engine or possibly a 9AGE hybrid. those engines use 4AGE heads and bottom end (9AGE uses 2ZZ bottom end) and 7AFE block.

[@scareyaf]

@@Videoswithsoarin That's what I was referring too, IIRC Tsuchiya runs a 7A block with a 4AGE 20V BT head. Think he mentioned it was better for torque and strength.

Better rod ratio is possible and bigger journal diameters

[@dorkusamoungus]

280-290 NA 10,000+, 45/48 dcoe's

[@motoiq]

Well they were the spec homologated motor so they had no choice other than to dominate FA!

[@dorkusamoungus]

We used to call them flying hand grenades. If anything went wrong there was nothing left. There were a couple of other engines that slowly crept in and eventually took over obviously with SCCA releasing the rules a bit then. Then went back to the one engine rules. This is just what I saw at regional/National level in the southwest division…. And it was quite a few years ago… I tend to get rusty on my thoughts. Like always… enjoy your vids

[@motoiq]

They were really a shit engine, I felt the BDA was actually better. Then you put that flimsy block as a stressed member in an FA chassis, boom! You had to take them down, change the rod bearings and inspect everything after every weekend, change the crank every 3 weekends, usually by then the main caps were getting beat out of the registers. The Mazda that replaced it was a way better engine, too bad the formula died right after, I loved those cars.

[@dorkusamoungus]

Yes the BDA was a much better piece… I got a couple drives in the Alantic’s back in the 80/90’s. They were explosive!!!. I knew they were a little temperamental on longevity. I don’t remember any production motor being that strong. ( with comparable mods) that was a rich man’s class. I am definitely not arguing that vintage builds compared to today, there is no comparison…. Our sleeves and lighter weight pistons and better quality rods are quantum leaps over that stuff. I still think for what it was it was still impressive.. I know you feel like they were junk. It was a good level at its time. Nothing like today. Have a great evening!

[@sparkster_6087]

FYI the 42mm cranks in these engines are good for stupid horsepower, PSI Racing has seen no problems with them going to 600whp. You only need to think about a stronger crank if you want to sustain 10k rpm for long periods or are throwing huge horsepower through the little 1.6. 42mm cranks were taken to 8400 rpm stock (rpm chosen by Toyota with general builds) once balanced they can keep higher. Typically the limiter of the engine is rods, rod bolts, or the sump turning so fast it cavitates or froths the oil. good video with pretty good summarization. A bit on the safe side but good info nonetheless.

[@motoiq]

You are right, forced induction and lower revs are actually easier on the crank and block until power levels get stupid. I should have said that this video is more NA focused.

[@sparkster_6087]

@@motoiq Ah, I took the information to generally. As an NA platform it definitely needs the extra strength. The 40mm cranks are definitely not up to the task, they or the rods tend to give out in even mild builds on early bigport engines when aroung that 160whp mark or earlier.

[@motoiq]

Yeah I found that 170 whp and not much more than 8k rpm was the safe limit with the small cranks.

[@intraterrestrial69]

I wouldn't say the 116 hp was special my friend. Some Honda ZC engines did that in 87', and almost that even earlier on carbs. That's decent specific power, yes. Then there was the original VTEC 1.6. It could do 8 grand and 160hp in 89'. Honda had them beat. However, the 11k ability and sound of the 5 valve 4AG is something amazing that must be respected and recognized.

[@CLINTSTER77COX]

I have a 7afe and 2 Sr5 1986 single carb motors. Anything useful with these

Not really not worth building. You can make good use of the 7AFE block though to make a 1.9 liter long rod engine with a 4AG head.
