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!

Pressure and volume of air are a completely different thing. You can run a small turbo and boost 12, 14, 16psi all day long, yea itll spool up insanely fast. But if you run a bigger turbo and boost 6, 8, 10psi (same power as small turbo boost) it wont spool as fast. Yea that guy that told you that was correct to some extent, that extent is how big or small your turbo is.

I have a 94 st with a newly swapped 95 7afe in it with only 124k miles. 4afe turbo kit sitting up in my room (yes 4afe exhaust and 7afe are the same) just waiting on injectors and fuel pressure regulator and im hiding in my garage for a weekend to install it. Anyone know if brown top (93-96 325cc 2jzge) injectors will work fine? And i need a good piggyback or way of tuning. Any cheap ideas?
