Supercharged AE 86 20v? what do i NEED, NOW?

[killaziggy]

i recently purchased an AE 86 for my 91 celica. i also have the 4agze supercharger. what do i need now, Pistons i already know. do i need the 4agze ecu? fuel pump? rods? i am trying to be as cheap as possible cus i already have the 91 celica efi. and the 20v 4age cpu what else do i need remember cheap, do i really need forged rods and a dry sump pump?

Huh??

What cars getting the motor, and what motor is it, and what do you want to do to the motor.

Sorry I just found that impossible to follow.

[REN69]

an AE86 for a 91 Celica???

the rest of the question... You lost me at hello dude!

[AVANT]

Grammar and Vocab check please. You're jumping around everywhere and parts of it don't make sense. I'm lost.

If you didn't already know, there not all 4AGE engines are the same, so not all their parts are interchangable either.

[killaziggy]

ok let me break it down vocational style
i have a 91 toyota celica ST which has a 4afe engine
im swapping that engine with a 4age
my 4age is a 20v, the silver top kind, not the black top
i wish to super charge the 20v 4age, which is an AE 86
i know that this swap and mod is possible
i have the super charger from a 4agze, which was in the celica STX
i assume that i need new lower compression pistons
the 20v 4age AE86 has 11:?;? compression
i can get pistons that do about 10 or 9 with clearance for 5 valves per cylinder
my question is? do i really need forged rods? im trying to be cheap?
do i need to augment the fuel control which is currently the celica EFI?
Do i really need a dry sump pump?
do i need a new fuel pump? there both 1.6 if that matters.
do i need to upgrade the radiator? ill probably do that anyway but i want the power now!!!


insigt please professional opinions only dont tell me to do something that could potentialy kill my new motor

[lifeisviewtiful]

ahahahahahahahahahahahaha, he talks about 2 separate cars and 2 separate engines........buwahahahahahaha

[lifeisviewtiful]

you bought an ae86 for your 91 celica. what, is this so they can mate to make a 4wd corelica ?????

[lifeisviewtiful]

while we're here talking gibberish.........

guys i was wondering. if i wanted to turbo charge my lsd, would i need low compression gears? i think trd makes some.





i'm just busting chops, honestly you are better off doing either one of 2 things

just throwing in the 20v just the way it is

or getting a regular 4age and just use 4agze internals(or just get a 4agze...lol). trying to adapt a 4agze supercharger to a regular 4age 20v will be a pain in the ass since the intake mani's are different on each. also there will be some serious tuning/wiring issues(the main issue right here), with the individual throttle bodies alone. i would imagine space might be an issue as well (don't quote me on this). also from articles i've seen the 4age 20v isn't really a good engine to run boost on. the compression ratio is 11 . i know you mentioned the low comp pistons. but with all the money you'll spend trying to adapt the supercharger to that 20v and making it actually run like a daily driver.........you would have been better off just getting the gze.



why are you even bothering supercharging the 20v. if you want to spend some serious money just go 3sgte.

nothing funny about the project... IMHO!

MOTOR... you have to distinguish the version of the ST 20V. there are 2 kinds. the 1st version has 2 throttle cable "thingys" and the 2nd version only has one. i hope you have the 2nd version.

CON-RODS... if it's a 2nd Gen 20V ST then you don't have to worry about the con-rods coz the bottom end of the 2nd Gen is identical to the late Gen MAP GZE. it's strong enough.

PISTONS... you need to get an aftermarket forged pistons with 5 flycuts. it's not advisable to get the GZE forged pistons to cut it coz it'll loose the coating on the pistons.

lower comp pistons is preferrable but the stock pistons should be able to take 7 or 8 psi. as long as it's properly tuned.

INTAKE PLENUM... since the motor is on a RWD car, the intake plenum was prolly modified with it's opening on the front or if you're looking at it horizontally it's on the left which should be on the right. you can easily post yours up at club4ag and exchange it to a stock one. i'm sure those guys will want it.

COMP RATIO... the ST 20V is 10.5:1 not 11:1

ECU... you have to use the 4A-GZE ECU or get an MS set-up

FUEL PUMP... any high flow fuel pump should work

INTERCOOLER... you need it!

RADIATOR... you need a good working rad!


MY ADVISE... sell the SC set-up and opt for a turbo. it'll be easier to mount and more boost later then get the MS set-up.

read the specs on the 20v from a ae101 levin and it said the 20v st had compression of 11

i dunno where you read it but it's wrong!

[killaziggy]

the 4agze sc has its own intake manifold setup will that bolt up to the 20v
its a 20v 4age Ae86 how do i tell what year it is, intake enters the same way as my celica but the sc basically changes that a little.
how do i tell what gen the 20v is?
all i know is that it has 4 throttle bodies? to thingys?
you neeed to buy too much stuff for the turbo? i only want 200 to the wheels
i really want the sc setup mostly to avoid all the turbo accessories.

thanks for the info, its a bitch trying to find rods

3sgte is way to much work most celicas are only fwd and almost all 3sgte are all wheel and expensive and rare. i would need a whole knew tranny from a rolla or MR2 a real pain in the ass. i just want the sc how hard will it be to mount the sc?
sc is at 12 psi? i need the low end torque to add to the high end 20v im greedymust kill honda

thanks for the positive info what else can you tell me to get this done i dont want to be like anyone else!! ill turbo wen i get my ass whoped by a civic a few times but for now this will do cus i got some cash to burn.



are you the dude with the lotus from club 4ag

All you need for information on 4ag's

What micro214_kp61 said is right, also I have no clue what you mean by 4age 20v AE86 it makes no sense at all, is it an ae86 with that motor or is it a 4age 20v that was in a ae86.

That applys to maunals only (1st gen auto silvertops had one linkage).
Toyota did this just to confuse you.

According to the toyota EPC silvertop rods cross over to corosponding GZE's
(ie. of the same year) and the prefacelift ones i've seen are pretty masive.

8.0:1 pistons will clear the valve on a 20v head, (as the piston is dished) can't say for sure for the 8.9:1 ones but I doubt they would hit either.

I've seen a stock silvertop intake plenum blow apart at 9 psi, so you may want to look into an after market one. (also FYI the airboxs implode at 6psi)

Totally agree a turbo will give you far better results, and is easier.

Sorry to be picky, i'm not trying to get at anyone.

thanks for the corrections punter.

- since it's only for MT STs that use 2 throttle "thingys" (still don't know what it's called! ) are the intake port shapes of the M/T and A/T 1st Gen the same, i assume they are. just want to be sure.

- i totally forgot that he'll be boosting it while i was typing the intake plenum part. you're right, he needs a custom intake plenum.

- i don't understand what you meant by... According to the toyota EPC silvertop rods cross over to corosponding GZE's (ie. of the same year) and the prefacelift ones i've seen are pretty masive.

from what i saw between the 2 they're identical and i was told that on the EPC, they have the same numbers. i personally don't have the EPC program, well i do but can't seem to make run, hehehe.

- hmm... i'm still not totally sold about the GZE pistons being used on the 5 valve head. if isee it with my own eyes then i'll be ok. or if someone who'd done it can assure me then i'd do it for sure.


punter.. thanks for this...
