[yota1994]

hey guys...i know that there are a few people that have turboed their 7AFE's to make 7AFTE...but i want to go a little more crazy and something that no one has ever done that i know of so far. i am wanting to make my 7AFE a 7AFTTE. wanting to twin turbo it...was wondering if anyone has any ideas and suggestions. thanks for the advice

TT = SUPER LAG

1.8l on a TT motor will have such lag issues

look at cars that come factory TT.

supra
skyline
etc.

there motor displacment is around the 3.0L area....

exaust gas is what spools your turbo/s and u wont have enough to spool 2 of them from the 7a...

sorry to kill the dream,...but someone was going to.

Craddle you are looking at it from the wrong perspective.
TT helps REDUCE lag when you wana use a larger turbo, (though the 7afe would blow up under a setup using it)

TT setup would require 2 different sized turbos

the first would be a smaller turbo say....T3 40 or 50 trim.
It will spool lower in the RPM, practically 0 lag and give you that off the line down low boost
it would be feeding an attached larger turbo...say like GT30..or a large T3/T4 for high boost levels
The smaller turbo creates the down low, lagless boost while spooling up the larger turbo which, effectively takes over by the time the little turbo has run out of breath..

a better decision would be something like a TWIN CHARGED setup, running a ~6psi pulley on a supercharger, which spools up a larger T3/T4 50 trim

While twin charge is cool, most people have proven its completely worthless when you can just use a single turbo for more output.


You could try and go the route of the rx7 FD setup. But with that is the fact that each turbo would only recieve 2 pistons which would do very little for spooling. In the end this wouldnt work well either.



I guess using bike turbos would be your best bet. They would be small enough to fit both, yet spool fast and produce a low enough power setup to not blow your 7a.

After all the headache though, it would be 1/8th the cost to just use a single or half the cost to just 3s it.
