Budget NA build that works - Smallport 4AGE

[@Garage4age]

If you have been watching my channel for awhile, you have likely seen this content already. At the time quite a few people found it hard to follow the build up of this engine, since I went off on a tangent testing different things along the way. So yeah, have re-edited and glued the relevant videos together, to hopefully make it easier to follow. Let me know you would like to see the same thing for the bigport setup. As it uses a few different parts and more testing along the way.

Just tough on a garbage engine. You can make 250whp on a stock k24 block, stock k20z3/a2/a head, stock tsx cams and good bolt ons.

A little tip for small scale engine builders Pop into your hardware or garden store and grab a small pump up garden sprayer or three replace the spray nozzle with a small hose or something and fill the reservoir with oil or cleaning fluid or whatever you’re likely to need to inject into small places. You can use these to clean or fill oil galleries flush brake and fuel lines and possibly fill differentials and transmissions And as you can get them for under twenty dollars even under ten dollars they can be cheaper than the devices made for these purposes that you might only use a few times.

[@timothyshearer6538]

Damn those Supercharger valve covers are sweeeettt

[@anomamos9095]

Serious comment. I remember advertising for Power or Economy plates or whatever the snake oil name was for them. The alleged purpose of them was to help properly atomise and mix the fuel with the air to improve power etc etc. They were usually a bit of metal that had holes stamped in it that you shoved under the carburettor. I really don’t know if any of them actually worked but the principal behind them is actually sound. Auto makers have gone from injectors that have one hole and just dump fuel to a wide variety of spray patterns and hole numbers as well as trying to optimise the intake, ports , valve position and combustion chamber design to eek the most out of the least. What some people do when they port a head and intake is they sometimes without knowing it is remove some little bump or ridge that the designers deliberately put there to help ensure the air fuel charge is evenly mixed in the combustion chamber. If you run out of things to test you might want to try different design injectors and possibly some kind of power plate if you want to risk bits of metal breaking off into the engine.

[@bboycieb9055]

[@theangel540]

Really great job! Thank for your time! 'll love to see an unseen setup with longer conrod (better conrod/radius ratio). It's our way for making good setup in France (peugeot 306 2.0 XU10, 205GTI 1.6 XU5). A longer conrod limit the imbalance between upper strock and down strock. less vibrations, less loss... 4AGE have too small conrod lengh (...making it's proper sound/identity...In add with valve uncommon angle). A 7AFE engine block/conrods with 4AGE internals must be great.

[@shahengovindpershad8599]

Amazing the difference with cams made on their own. They don't respond as well on the 20v. Would be nice to do something similar on the 20v.

[@Garage4age]

yeah 20v has bigger cams from factory. Plus you will find a cam of the same duration for a 20v will have less aggressive ramp angles, due to the smaller bucket size. even more so if convert the 16v to undershim/shimless buckets and use a cam profile to suit. so stepping up a cam profile on a 20v that same as a 16v cam on paper isn't really apples to apples

[@ImUrOBGYN]

Are you soaking your camshafts first so they flex? i just can't get mine in thru the oil hole in the valve cover no matter how hard I jam or hammer them! 🤔 Great vids as always! 😉

[@sandpiper1515]

I think a cool experiment would be to make UEL headers like for Subarus, I have also seen civics use them and they sound almost the same as the Subaru.

[@AmirPomen]

Any car will sound like subaru if they have 2 exhaust port atleast 4inches shorter than the other 2 of subsequent firing order... Subaru uses 1-3-2-4 (short on 1 & 3) If 1-3-4-2 then will need short on 1-3 or 3-4 or 4-2)

[@gedas3419]

Idea for testing: Some headers for example go from 4 to 1, 40mm runners merge into 60mm exhaust, but collector tapers down to like 55mm or 50mm and then tapers other way back to 60mm exhaust diameter. As a choke should increase velocity and pull-effect on other runners as opposed to straight runner to exhaust merge header. Would you like to test this idea on different collector choke diameters? Btw: thank you for this video.

[@Garage4age]

I have lots of video's where i test and try similar things. even in one of my more recent ones with the blacktop 20v it uses this kind of design.

[@brocklee9539]

Love your content. Your work comes up alot in conversations amongst the friends. I have one for ya. The orientation of the throttle body.

[@stugallop4561]

Another 10hp with red paint though!!!! Gold paint is too heavy and would affect the power to weight ratio ...LOL Thanks for all your long hard work but guessing you enjoy the tinkering especially during lockdown. Would race fuel and increased CR shed a wee bit more power?

[@Garage4age]

Upping the compression probably give a couple kw. I dont think race fuel is necessary. my other engine makes over another 30hp than this, on around 13:1 compression. this one is only 10.3:1. both are on pump gas.

Torque... at the wheels ! If the test is in 4th gear (1:1) with a 4.3 final ratio, then it's multiplied by that much

Yup as above. punch the rpm and power numbers in here wensensors.com/unipower/calculators/power_torque.asp to get the toque numbers, remember will still be minius the driveline loss since using power at wheels to calculate it. torque and power just calculations from each other along with rpm.

[@kadewiebe3067]

in your experience does the 4ag benefit more from higher lift or more duration? do you reckon using a 265/256 duration cam would give more power down low? i have some old hks ones sitting around... but they’re fairly low lift. i’m building an engine with 10.5 compression, and i’m torn between the hks and 193-bs for a street car.

[@Garage4age]

duration. To a point its not really the cams that will give more low down power, they just get the blame for it. almost all 4age's ive seen with cam upgrades, will have a big dip between 4000-5000rpm and only start making power from 5500rpm onwards. but as you can see in this video, not the case, matches stock power then pulls away from 4500rpm onwards. this is due to getting the bolt on parts right, mainly the headers and exhaust. people also usually leave the cams dialed to reomended spec, which usually isnt ideal.

[@fuzzayd4601]

So whats the general consensus? Small port better or big port better?

[@Garage4age]

smallport is better. not a whole lot in it though, esp once modified. there are at least 2 different bigport head castings which are quite different also. i tested them in the bigport version of this video

Not sure if someone already asked about a 1.8 bottom end...how would that fair, is it a more finicky type of engine? Pro vs cons between the two 1.6 vs 1.8

[@Garage4age]

Yeah lots of times haha. IMO for a budget build the 4a bottom end will win every time. you can just use a stock bottom end and rev it to 8500rpm. 7a will need to spend some money on it. will still suffer from all the same problems as a normal 4a. have seen plenty of 7a builds make less bottom end power than the engine in vid and also rev less. so smaller power band. better of spending the time/money on getting the bolt on's right.

easy on a turbo 4a. 7 rib block and 4azge pistons and will go forever on that power. NA not so much, 200whp is getting to the top end of whats possible and pretty hard to achieve, esp with nice powerband.

[@Loplyful]

@@Garage4age How about the rods? Would late bigport & early smallport rods hold? Since they're the beefiest to my knowledge

[@Garage4age]

@@Loplyful Yeah thats all my hilux has, just arp rod bolts. late smallport / silvertop 20v are all good as well

[@fregisz]

What throttle body butterfly valve size ITB used?

[@Garage4age]

they are blacktop 20v with oversized 47mm plates. pretty sure this engine would make the same power on the 45mm plates. just what i had hanging around off another setup

[@fregisz]

​@@Garage4age Thanks. I planing put on my opel v6 engine itb, already have 46mm, but afraid it can be to big, but looks like will be ok :D

[@Garage4age]

@@fregisz yeah will be fine, i run 52's on my other engine didnt loose anything down low over the 47's. if you think they are too big you can always try downsize the runner/trumpet. dont worry about having a step up in size when gets to the throttles. it doesn't matter as much as people say,

[@kpraz]

what trans is this

[@Garage4age]

t50

[@roboman2444]

It is ironic you put ITBs on an engine that said "SuperCharged" on its valvecover.

[@dilsher12]

Really stout numbers for the little guy should be over 200hp at the crank

[@ProjectoD77]

Close to 200, but not over. (190/195hp would be my guess)

[@jareknowak8712]

Usually there is a 15% loss on the drivetrain in RWD.

[@hojnikb]

@@ProjectoD77 Just to think about it, this is pretty awesome for a 1.6 NA

[@Garage4age]

probably around 190 i would think. pretty hard to say, driveline loss inst really a fixed percent. still not bad for a smoky old junker

[@maxrocatansky5516]

@@hojnikb and power to weight would be good..this little car would hurt a lot of feelings against bigger cars.

Can i use 193 C with a similar combination on this video ?

[@Garage4age]

Yes, imo they are a better cam. I would have ran them in this engine, but had the 193b's hanging around. Remember the bigger you go the more sensitive the engine gets to exhaust and intake tuning. and harder it is to get the engine to work over a big rpm range. should be looking at some good head work also.

[@juancarlosaponte3528]

I got also a set of wiseco pistons to do a different build . Do i need head work , valves etc fot the 193c cams?

[@Garage4age]

​ @juancarlosaponte3528 stock valve size is fine. oversized valves need bigger seats and a lot of porting. or else will actually be worse. Haven't ran the 193c on a stock head. but have tuned a car with 193b on stock head. it made 119kw from memory. head in this video has had a little port work. i would suggest at least to tidy up behind the valves and in the chamber. na tuning is all about stacking small gains together. so dont expect big gains from just doing one thing. unless that one thing happens to be the only thing restricting the engine for course
