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.

People can now see how tough it is to make more real world HP in a NA engine without some weed though out changes. Bravo

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.

That's the best Cam install I've ever seen! The effort that goes into these video's is huge. Big respect.

Gotta love ITB's no matter what powerplant they're bolted to. Nice solid gains with the lumpy sticks and the advance too. Hats off for some real world back to back pulls with some useable data/ plots. 👍👍

This is the kinds of builds I like. just straight to the point and not wasting our time

i have alot of respect for the 4age engine as ive owned it for 7 years with 480500kms and it still went like a bullet. i crashed it in 2012.....i still want one again...no lie just a awsome engine

Haha mate those camshaft upgrades will never get old... a little scraping can be herd, but thats allright ;) Great video once again, thank you!

Memories. I built one back in 06 with the help of some good friends. Miss my 86.

Gotta love the water bottle that's repurposed for lubing your parts.

Love that you use a CRT as a monitor it has real old school vibes.

solid build! just reassembling a smallport after dismantling the bottom end, only to find it had a fresh rebuild recently!

Such a good video helped so much learning

Love the gold block 😄🤩

Damn those Supercharger valve covers are sweeeettt

love the Starlet !!

That engine was BEGGING for a cam upgrade! That looks like a bone stock vs FBO comparison chart.

I really enjoy the camshafr installation...

@garage 4age can u pls do a build vid on how you made tour headers 😍

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.

I'd love to see u build up an 7age and do few different tests

Still one of my favourite motors. I've owned a small port ae91 corolla and a black top with 6 speed and lsd in an ae101sprinter hatch. Miss them both

Lmao loved the camshaft install!!!

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.

If only all 4A sumps, scraper plates and crank timing belt gears came of this easy....

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.

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.

Gold paint def carried the engine 💪

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.

Like the sounds, nice work

Easly 10hp more with Svarovski diamonds on the pistons. Every tuner knows that diamond fits to the gold. :)

Camshaft insertion had me in tears ;) ahahahahha ! great video showing real evidence and justification for parts used, love it! Sub'd because of this video! :)

Very nice..30hp gain on a 1.6 NA motor is pretty respectable would love to see that same motor with some more cr haha.

Really great job, man 👋☺️

fantastic job!

You know what video you should do? Port and polish a head and dyno it against a stock head and compare the difference but also do a video of the porting. Same cams same valves. Been searching all if youtube for a video like that but cant find any, im sure alot of people would like to see this.

What i'd do to have a dyno at home.... my poor twincharge would cop a flogging!! hahahaha

One day i'll chase a 4age for a little car like this.

Love your content. Your work comes up alot in conversations amongst the friends. I have one for ya. The orientation of the throttle body. As in opening of the throttle plate with axis of the throttle plate horizontal versus vertical. I've always wondered if there is some low end turbulence occuring in the plenumn.

That timing pulley came of the crank way to easy

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! 😉

Very good video. For NA power seems like every little thing helps, maybe lighter pulleys, idk what oil you run but maybe some super slick synthetic kind, besides a major engine overhaul idk what else to throw at it.

gold paint, most important part

4ag FTW!!!!!!!

it would be interesting to see what it does with short runners and the 193b cams

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?

Thanks one more time.

You should do a turbo 4age build see how much more power you get out of it

Love from malaysia❤️🇲🇾

Love your videos . Seen them multiples times to understand that hat in want with my personal build . Im stock on valve springs right now . What pressure its recomended for valve springs on those 193

Shiber, use it!)

Very nice, good baseline build to do! How hard was it to 4AGE swap the Starlet? Simple because they have 4K-E/4K's?

Great engine the 4age. I have a corolla Tsport and I'm really exciting with the car after a leon cupra R and ep3 typer! What's your opinion about 2zzge?

Yeayyy gold blockie

Good work. What’s up with the torque figures? Dyno not calibrated, or is this turd the biggest torque monster in the universe?

When you advanced the intake cam 5 deg then 10 deg, that's at the cam so it's 10 deg and 20 deg at the crank then? That's quite a lot.

Clean botton end for 300k, amazing little motors eh.

Love it. Have you ever tested the distance between the head and the itb's ?

have you ported and polished the head too? I've got a ford 1.6 zetec/sigma in my car and I wanna make a bit more power with it, these videos are great for me to see what you can do with a 1.6 na build.

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.

I’m from Sa and I have a 20v 4age. I want to know how much power gains will I get if I port and polish the head. Can u please do a vid

Please bring that hilux to the dirt drags this year if they aren't going to be canceled

Did you paint your nails gold as well? Cute

Awesome results! Any idea what the actual static compression ratio is?

Did you use diferent springs and retainers for the cam changes . Or did you use stock ones?

Hey man, Just trying to work out upping comp in mine with the 193B in a small port with zero deck height, stock small port pistons and was going to run a 0.8mm TRD gasket. Was that head you used shaved at all or do you know your combustion chamber cc's?

Rotrex!

Your using a big port bottom end, with red top pistons ? I thought they had different size wrist pins?

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

Would love to see dyno # and 1/4 miles time/ trap speed. Never understand what's the point of all that twist long header?

While dismantling, you don't use the impact from the begining on the rods for some concrete reason?

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

Genuine question: Why do you spend so much time optimizing an NA 4-AGE build for such low horsepower? Why not build a high compression, high rpm motor for more power? Or do a swap?

Why is the bigport block preferred to the smallport one? I thought it was the other way around 7 ribs vs 3 or whatever

Do you think that building a 4A-FE in a 91 Corolla wagon is worth it? Asking for me, not a friend.

With a Link ECU, what sort of difference does it make? I have a 20v Blacktop with Kelford cams but its on a stock ecu with a SAFC 1 Piggyback. Wondering if it's worth the upgrade.

Hey mate noticed your not using a cas but running coils how did you achieve this do you run a trigger set up on the balancer or what’s the go ?

What new parts did you use, if any, for the block refresh? Bearings, rings, studs?

Hey there i'm not sure if you'll see this because it's an old video but what itb's are you using and where did you get them from? I want to use those on my smallport 4age and want to see if they'll fit if you can give me links or info on all the parts for the itbs. Thanks so much.

I have a big port series 1 motor would i make more power with small port head with my 276 piper cams that i run in my bigport

I own a 4age and a 4afe my question is how much rpm can I spin using the stock shim over bucket lifter. 4age is na and 4afe will be turbo . Looking for 8k rpm reliably for both engines

I wonder what kind of power could you extract from a peppy engine like this with a freevalve like cam setup?

Hey I'm kinda new in the 4age engines but that's is an 4afe block ? Becouse I did not see the oil squirter I may be wrong

Have you used a 40mm crank? I'm using one in a build and I heard they don't like high revs(8000+).

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

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

How do you find the half size radiator in the kp? I have been running one in my 4age suzuki sj but the thing keeps overheating. Any tips?

What is benefit of using the bigport block over the smallport?

Garcia Matthew Brown Betty Brown Sandra

What dyno are you using?

What brand of gaskets do you use when rebuilding?

Can someone convince me of the potential of 4A engines without spending heaps of money in terms of performance? I'm very conflicted on building my bluetop or just going with a K or rotary swap. Thanks!

would you ever look at doing a 7age?

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

What throttle body butterfly valve size ITB used?

What's compression ratio on that engine?

Hi I'm building a budget blue top I need a few bits and pieces can I email you a wee list?

Pardon my ignorance, but what make of car is it?

what trans is this

Use a real N/A 4 banger get a K-Series
