Building the Toyota 4A-GE!

[@snap_oversteer]

Always nice to see videos on the good old 4A! I'm currently building 4A-GZE for my AW11 MR2, parts are harder to come by especially in Europe, but MRP has great stuff indeed and I've already bought couple of things from them.

Thanks so much Mike for sharing your knowledge on the 4A-GE! I'd love to know more about building a 20v silvertop or blacktop too! (And 7A-GE etc!) A lot of this knowledge is lost with the forums going down. Thanks for preserving it for the next generation who loves these cars/motors.

The forums are still up though, incl the aussie ae86dc one. The problem is lazy people turning to fb groups (which are more for sharing final results) and asking questions there, with no way to store or archive most of the knowledge.

ive got a AE92 coupe which i manual swapped and put a blue top 4AGE from an 86 MR2. i rebuilt the 4AGE before hand, new pistons, bored 82mm, decked with the TRD 0.8mm head gasket, HKS 272 intake and exhaust on adjustable cam pulleys, stand alone ignition (no distributor) and two weber DCOE 40s and straight piped with stainless headers plus a few sort of reliability mods like the MRP timing belt stabilizer and all ARP bolts on the bottom end and the stronger 20v oil pump. it really takes off, i put 91-93 octane (north america) and have the ignition timing up just before knock. great acceleration with no delay!

[@preshandpereira4035]

yeshhhh fellow Malaysian!

[@_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.

[@Adrianzx]

Even though I feel burns stainless X-Pipes are a tad expensive, this video hits all the right buttons for me. Toyota, nostalgia era, itbs...

[@zeroyon4562]

Great video. Hard to believe they’re a 40 year old design now! They sound so great, and were and still are a staple at every motorsport event in about any configuration you can imagine, as a 2A-GE for example. I have a soft spot for these (having owing 3 AE82 FX-GT and an AE85 with a 20v back in the day). They’re fragile alright, I’ve run bearings a few times in the bigport motors without the external head drain like the smallport has. Great to see NZ companies and guys like Garage 4age keeping them alive too.

[@firstielasty1162]

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.

We used to call them flying hand grenades. If anything went wrong there was nothing left.

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.

@@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.

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.

[@motoiq]

Better rod ratio is possible and bigger journal diameters

[@scareyaf]

@@motoiq Awesome, cheers for the further info!

I’m waiting for Mike to spill all his knowledge on the SR20.

[@motoiq]

That's coming soonish.

Would love to see a Toyota 3URFE engine built out with turbos instead of the supercharger to see how much power those engines can reliably make.

Such soothing voice (like asmr) to listen for hours! Do you have an opinion on 3SGTE? I would like to see if your video will talk about building 3SGTE :D

[@motoiq]

Not yet but working on it.

Fantastic... If you don't already know of Garage 4age YT channel you will really like it... A fellow kiwi guy runs the channel and has around 220hp out of his 4age

[@motoiq]

220 is pretty standard, a really well built one can be 230 plus.

I know that, did I say otherwise by mistake?
