Engine 89 corolla GT-S

If you want to go full N/A then you should do a Blacktop 20V 4AGE swap.

85 to 91...... 85 to 89 had t-vis and "low compression" 90 and 91 were smallport highcomp

88 to 91 were front wheel drive ae92 chassis 85 to 87 were rear wheel drive ae86 chassis (there was a rwd sr-5 in 84 also ae86 chassis)

interesting. When a lot of people talk about converting there SR-5 to a GT-S. is it all looks or do they actually reinforce the rear and convert it to rwd?

Quick question for you turbo4age.

Since your the big 4AGE person to ask im sure. What are the best specs youv seen on a 4AGE N/A engine before? Im talking 16V only. not the 20V. You can include 20V also, but im more curious about the 4AGE 16V specs. Im talking hi-comp pistons, and everything done to be the best.

Thanks!

I think around 160-180 hp. If you're looking for over 200hp out of the 16v, then you're probably out of luck unless you go FI, but I could be wrong. You could always just get the 4agze, which is supercharged.

Damn, thats a lot for an engine that is just over 100 stock.

89 corolla GT-S

HELP ME UNDER THE HOOD! i've got a 89 rol gt-s with 70,000 miles on the engine and 170 on the trany. i have $5000 and i want to modify all performance. i dont know any swaps, should i go for it or am i better off buying another auto

there's tons that you can do to a 4age...... what do you want.... n/a or f/i.....

there are also tons of swaps you can do as well

that blacktop and 5speed is a DIRECT SWAP

they made the GT-S up to 91??

I dunno i just like RWD to much

so why couldn't you do that to any of the later corollas? I meen the GT-S tranny fits the 20v. Could you convert the 00 levin?

Well at least i think thats how they drop the 20v into the corolla..

the 88 and up corollas are all fwd, with fwd trannies and fwd chassis'

the bolts that connect the tranny to the engine are in the same spots, but the trannys are completely different

engine mounts on the A series engines are the same, thats why you can mount them in different chassis that came with the A series...... the newer fwd A series engine bays are like a transverse of the rwd engine bays

here's to confuse things more.... all 88-89 4age's in the US, at least, are bigport redtops.... so when you hear or see "redtop" for sale, it may not be the smallport you are looking for.... (and if you go to www.mr2oc.com they don't believe it exists.... *rolls eyes*)

there's more to an sr5 -> gt-s conversion.... especially in the ae86.... on my ae92 i'm roughly 80%? done i guess.... at least for the ae92, here are the sr5 & gts differences:
GT-S has:
sideskirts
spoiler with 3rd brake (sr5 had no spoiler, 3rd brake was in the rear dash)
rear disc brakes (sr5 has rear drums)
4a-ge and 4a-f/4a-fe
Seats were different (though, I like my sr5 seats more than any GT-S seats i've seen)
Gauge clusters were different
There is a voltmeter and oil pressure gauge pod (sr5 uses switch-style lights)
23mm Swaybar up front (sr5 has none, however rear swaybars are the same)
strut brace (sr5 has none)
serviceable struts/cartridge style (sr5 had non-serviceable struts)
C-52 transmission (sr5 had c50.... c52 in the ae102 has different final gear ratio)

as far as pw/pd/sunroof etc.... those were options you could get on either an sr5 or gts.... the "spotwelding" isn't true.... i have a good friend who owned an sr5 for 14 years and through those years has had several gt-s's (finally sold the sr5 and has a gts now) and never saw any differences there.... the sr5, however, did not have an optional LSD like the ae86 gt-s did (no ae92 came with an LSD... but strangely enough the aw11 mr2's that use the same trannies had an optional LSD... rare though)

forgot that the GT-S got 14" wheels and the SR5 had the smaller 13" wheels (some came with alloys like mine, others came with steelies & hubcaps)

between the ae92 GT-S's:
88-89: i think the interiors were slightly different.... i think they used similar material that the ae86 seats had.... but the later years i wanna say used a softer cloth on the seats.... had the bigport redtop (t-vis) ~115hp (at the crank), lower compression... however it did have a 7 rib block (over the ae86's 3 rib block)
90-91: slightly different interior... used a larger flywheel (though, it's been said that the smaller one, even though it's heavier, spins faster because there's less outside rotating mass), and also had larger brake surfaces

.........................

Go get a 4AGZE it will feel faster than the 20valve cause of it's TQ. It's also easy to install. I would keep it N/A and get the Blktop 20valve with a LSD.

haha.... a gze will "feel faster than a 20valve" because it has more torque AND hp....

If you get turbo pistons and turbo a blacktop or supercharge it, it would have more than the standard 4AGZE though, hehe.

ok... you do that.... go forced induction on a blacktop and WASTE what the motor is about... and the lightweight internals can't take it anyways

they cant take high boost levels...... but in comparison to a standard bluetop, youre gonna make a lot more power with a similar setup

OR....
some guy on club4ag used a 4agze bottom end with forged parts and has a 5th valve relief cut into the pistons and then put a 20V head on there with individual throttle bodies and turbo...... hes making like 300 horses..... you know who im talking about right? the coupe

no.... i haven't checked club4ag in a while (though, i should.... becoming more of a member as usual... now i have the mr2 and about to go look at a 2nd mr2... s/c this time)..... but i've actually heard a lot that the 5th valve actually causes problems.....

Silver or blacktop?

ken maeda's set up is a turbo 20v making about 250hp.

i don't know, since the head cover was is bling bling chrome. isn't it the silvertop have beefier internals than a blacktop?

Ohh my "Bad" I thought it was only a 10-5 hp diffrence and a huge TQ diffrence.

yeah but if he is looking to run huge power, then im sure he would do better internals so the difference in blacktop having not as good internals doesnt matter probably.
