7A-FTE made in Germany Options

[Hafkai]

Hi, after over a year of gathering parts my Celica finally is in the garage and gets her custom header, exhaust and some other stuff.
Yesterday we fitted the big Evo9 intercooler, i had to get the ST205 crash bar because the stock one is to tight, intercooler piping was done too and i'm very happy with it. I will use the stock ST205 air filter box, since there is not much space between the filter box and the engine, the IC piping is a little bit tricky but it looks like we found a good route.









The header will be done in the next days.



Short list of parts i'm using:
- Garrett T25 Turbo from a CA18DET
- Mitsubishi EVO 9 Intercooler
- E-manage Ultimate
- Innovate LC-1 Wideband
- ST202 3S-GE Injectors (372ccm)
- ST205 Fuel Pump
- Bosch Blow-Off from a Audi S3
- Custom Header and 3" Exhaust
- dozens of other small parts

Interesting. OOBE said that 8 PSI was the max on stock internals. No issues whatsoever though?

WTF? I NEVER said that 8 PSI was the max on stock internals. I've had mine to 15 PSI.

The "mechanical engineer" guy was the one that said that. I was the one that broke that myth here years ago about the 7A-FE not being able to handle more than 7 PSI.

No issues at all, it depends on the injection and especially the ignition tuning how much a 7A will handle without braking something. I tuned my 7A to run with an afr of 11,5:1 at full boost and retarded the timing a lot. It's absolutely important to watch engine knock while tuning.
8 psi is pretty safe on a good tuned 7A, 10 psi is the max i would give a stock engine over a longer period of time, maybe 12-13 psi with an water injection.
If you want to go higher you have to lower the compression and get some stronger internals...

I do know stronger internals are eventually necessary, I just thought that point was past 8 PSI.

OOBE, you lied to me! Okay, good then. What I'm really looking for is not necessarily a max, but a good point for a DD. What do you run daily?

So both of you guys, push the hell out of your engines so Ferdi has plenty of study material!
