here's a site that someone posted a while back, if you've got the money.... 7afte

Thats a kit for a 93-97 corolla which doesnt fit 100% on the celica so modification will be needed for it to fit correct

here's a site that someone posted a while back, if you've got the money.... 7afte

That turbo manifold in that kit is such a bad design for exhaust flow. I'd rather stick with the 4AGE turbo manifold idea. The bolt patterns pretty much bolt up. In my opinion you are better off buying the parts seperately the way you want it and save more money that way.

Pic of 4AGE turbo manifold.

the 4age manifold the outter pipes have to be cut and reweld to fit a 7afe flange also if you buy an ssauto one redo the welds than jet coat it

7afte is going to be as much work or more (rebuilt bottom end, custom header/downpipe, piping for tmic or fmic, a/f management, oil and water lines, etc.) than a 4agze. there is a good amount of aftermarket support for the 4a, and you'll probably get more reliable hp out of it.

as for hp, how close the numbers would be depends on too many turbo variables (what kind, boost pressure, eng managment, etc) to say. if you were to go big and run 9-10 lbs you could put up big numbers, but you'll need a huge amount of other engine upgrades too.

i vote 4agze.

ok doing a 7afte is no where near as hard a a full swap

for one you can run stock internals on 7afe and boost go look at the how to sections is covers a 7afte build you are right on the fact that the 4agze is more reiable for boost application but thats exactly what it was built for.

ive done the 7afte and a 7agte builds

in the end it comes down to your hp goals and what the car is used for track,drag or just DD

So Nik, can I run a custom built turbo setup for my 7AFE without changing out the pistons? I would love to add the Venom Fuel Pump and Venom Fuel Injectors as well as the Venom 400 with the turbo. I will also be using a 4AGE turbo header from ebay and running that with a t3/t4 turbo. Hhahahahah.

Too much E-bay.

In terms of manifold, do what you wish. I personally will be running a log style unit.

T3\t4= too big for a 7afe. T3 is ok.

Most people run 8-9 psi on a stock 7a,,, which is all I would reccomend for a 139k mile 7a. with a fresh 7a, however, I hear 11 psi is streetable.

get a walbro supra fuel pump= just as good if not better and cheaper.

There are lots of injectors out there to use, the venom are the most expensive

The venom 400 unit is totally useless. get a FMU like a greddy unit or a apexi SAFC.

*** I also say you need a wide band 02 set up to tune the engine, to do otherwise is reckless ***

as fallen stated i would go the fmu route or a FPR with 3 bar map sensor and bigger injectors

venom is overpriced

on the 7afte a t3 is better matched for how much the motor displaces a few of use have had good results with 50 trims and 60/super 60 trims in the t3 size

i would recommend a catch can also and start at 6 psi and go from there also go to the dyno to tune it if possible
