Hello!

First of all i glad to find this amazing forum.


Well i got a Celica 1.8 ST 1995 7AFE,
and i got 4AGE motor from a friend.

I read is possible to change the head of 7AFE to a 4AGE head!

But i have some doubts...

1. What gains can be expect?

2. the change is straigth ?? No need to change anything ?
Is just bolt the 4AGE head on 7AFE block ? ....If not what i need to put from the 4AGE motor in 7AFE ?

3. Do i need the 4AGE ecu to run this ?


Thanks so much

search up 7age on google and you'll learn ALOT.

4a ecu and more, the engine sticky has some good info on this.

You can even contact Nik on this forum about the 7age.

Hi!

I pass my day reading stuff about 7AGE.
I learn a lot of this...

So to simplify part list is:


- 4AGE head (small port or big port)
- 4AGE pistons
-Timing belt Porsche 924
- 4AGE ECU

Do i miss something??

what 4age are you goin to use, ii was actually thinkking of doing it in a prism 91 gsi with a red top...

there is alot of info in there and there are a few ways to do it this is just the way i did mine

Red Top and Blue top are not real good definitions I own 2 red tops an 88 large port TVIS
and a 91 small port. The 91 prizm should be a small port as well.

1. at least 30-40hp gains
2. nope. longer throttle cable and wirings a bitch.
3. u should if u want to take advantage of vvt and the better MAP.

assuming ur using a 20v bt
