6G Celicas Forums

[color="#FF0000"][/color]Hi Guys ..

Iam new member in this forum and i benefited a lot after i read the topics..



in this week i will start my project in my Corolla Engine 7A-FE .. I know alot of members will suggest for me to change the engine but in our country difficult to found 3gs or others.


My goal exactly to make my car for carshow and dailyuse.

I will use RB20DET Turbo .. what do you think guys it will be ok?


And i want to ask what i will need to boost my 7a with stock internal block



NOTICE: My Transmission Automatic..!!

search "OOBE" in the search bar in the top corner.

he is one of the first 7A automatic turbos on here.

go for it my friend.

You will NEED an auxiliary transmission cooler to allow it to handle the extra power, if you can find someone who can rebuild the transmission and modify the valve body for better faster firmer shifting that would be very good as well.

Thanks my friend .. i will search now

Thanks guys ..

i send message to OOBE



Guys what about the oil i need two ways in and out to the turbo .. from where can i take?

Thanks Dear .. i will use good cooler to the transmission i need maximum 6 to 7 PSI

no he wont, not with low boost.

I disagree, but that's OK.
He already lives in Bahrain, which gets rather warm in the summer and stays pretty nice in the winter.

100F average summer temps PLUS a turbo ontop of an automatic transmission dumping heat into the cooling system. He'll likely want to add more cooling capacity, especially if he's running a front mount intercooler which would be dumping warmer air through the radiator. If he gets an aftermarket radiator then he HAS to run an auxiliary cooler since there won't be a trans cooler built into the radiator. Regardless of that, the stock trans cooler is mighty wimpy. Calling a cooler is a misnomer, it's a heat exchanger. It warms the fluid faster when it's cold and keeps it from getting entirely too hot later, however since heat is the biggest killer of the automatic even the 210-220 F coolant temp is a little on the high side for an auto trans. Add atop that 30-50FT/Lb's more torque to a trans that's old already and you're going to add stress and heat that maybe it can handle maybe it can't, it will work it's best at about 180F fluid temps. I suspect in the heat there with the added power he'd be seeing fluid temps north of 230 and that's where things start to degrade.


And about the valve body work, at stock power levels the A245/A246E have a slow/weak shift from 2-3 right off the bat that gets a little worse as they age. Slow shifts are slow because things are allowed to slip as they apply, slipping is friction, friction makes heat. Adding power to a slow shift will just make it slip more because of a weak apply. Correct the 2-3 shift softness and it'll help a lot. Other than that and the general compromises that Aisin makes between shift speed/firmness and comfort (which are inherent to any trans for the most part) the A24x series are solid units.

Dear i want it for low boost .. Maximum 6 PSI for carshow and dailyuse..

Thanks for reply

Our weather very hot specially in summer .. But i will use it with low boost .. maximum 6 psi .. what i will need guys?

Injectors? fuel regulator? fuel pump? Blow of valve? whats else guys


i will buy the parts this days i need suggestion

Thanks for Replies

OOBE won't reply...he hasn't been active in over a year.

Did I miss what you're tuning it with?

Thanks Playr

These are very important topics..

I will use apexi Super AFC

What i will need more?

SAFC in my opinion is not sufficient, there is no timing control and very limited fuel control.

If i will use it without tuning..any problem will happen? for low boost i will use it on 6psi maximum


Now i took RB20DET Turbo
Intercooler
Blow of vavle
custom manifold


i think i will need also injectors and fuel pump

if its an older engine, he could turn the distributor back. That will work just fine.

RoadRunner, read some of the things I ran into http://www.6gc.net/forums/index.php?showto...;hl=7a-fe+turbo

Good luck on the project 7afe turbo.. they are very fast arournd 15 psi and up.. the throttle response and turbo combo on these engines jump acceleration fast..
