16 4A-GE Question?, Please Help Options

[94STcoupeKyle]

Tomorrow i am picking up my spec japan 16v 4A-GE

it only has 25,000 miles on it

im only paying $75 plus some dj equipment for it


ok heres the ?, He said it came out of either a 1985-1989 MR2 (MK1) or a 4th or 5th generation Celica,

Would this be better or worse for my 94 7a with 215,000 miles on it?

Would it be a little bit faster or slower?

Would this be pretty easy to swap into my st? like would it bolt up to my stock tranny and would the motor mounts work?

Oh man, you have a LOT of research to do. Those cars never came with 20V 4A-GEs. Do you realize that you need a lot more than just the motor?

[94STcoupeKyle]

o sorry i ment to put 16valve silvertop

like what else would i need?

would this hook straight up to my tranny and go with my motor mounts?

i have a 94 7A-FE would it even be better for it to swap for the 16 valve spec japan 4a-ge? or would i lose power?

my car has 215k miles on it and this one only has 25,000

yikes! You need to do a LOT of reading. Some things you're gonna need off the top of my head... AFM, coil/ignitor, dizzy, manifolds, wiring harness, ecu, coolant plumbing, and a major wiring job. Let's hope you're capable...

Not to mention that there is no 16v silvertop.

Sure there is... take a wire wheel to the valve covers... ;]

would the 16 valve 4a-ge be better or worse than my 7a?

would it bolt up to my stock tranny and the motor mounts?

and its a japan spec 4a-ge if that makes any difference

What do you mean by "better"?

would it bolt up to my stock tranny and the motor mounts?

Yes... but not to your power steering, a/c, coolant lines, or anything else.

and its a japan spec 4a-ge if that makes any difference

No

would the 16valve be any faster than my 7a?
i know the 4a is higher reving than the 7a but lets say in a 1/4 race who would win a 7a or a 4a?

it comes with the ac compresser

Does a 16 valve have better internals for turbo compared to my 7a?


is it anywhere close to being as good as a 20valve silvertop?

Yes. 4A.

Not really.

Not really.

o ok j/w wandering because i was searching for 16 valve stuff on here and there was a post that said he has a 16 valve 4a and he said he had no problem keeping up with coomer which u know has a silvertop.


so if you had the chance to get a 4a for just about free because you can trade some stuff for it would you swap your 7a with your new 4a?

would it even be worth it?

It's not as simple as swapping the engines under the hood. That's merely the easy part. The hard part is the wiring... and collecting all of the missing pieces, which you're definately gonna have a bunch of.

As for thomas (toyotaspeed90), the guy who "beat" coomer... heheh... that guy likes to talk a bit of trash. He does know his car stuff... but when it comes to racing... eek. Also note... Coomer's silvertop at the time had a lot of issues with the wiring and VVT, so he wasn't running in peak condition. On a side note... he mentioned only running low 16's in his 4AGE Corolla... a time I matched with a 7AFE. Considering the corolla is lighter than the celica...

There are 2 MAJOR versions of the 16V 4AGE. The bigport, which makes about 115-120 hp and 110 ft lbs of torque (most likely the ONE)... or the slightly rarer smallport 4AGE (the one thomas has), which makes 130-140hp and 105-110 ft lbs of torque. Neither of these will hang with a silvertop 20V... both will beat the 7AFE, neither of them are neccesarily easy swaps because there is a significant bit of wiring that needs to be done.

What he said ^

The hardest part is the wiring, which I can do for you for $350.

Hey thanks for the advise, it really helps, Yea i know i can do everything but probably not the wiring! i will probably be getting you to do that ok?

ok tomorrow i will be picking the 4a up and i will be posting pics so you all know what it looks like.

About how long would it take for you to do the wiring?

[Dr_Tweak]

About a week or two.
