6G Celicas Forums

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

Nicht schlecht, Herr Specht
(Not bad Mr. Woodpecker )

Has it been on the dyno yet?
What's the power output?
Why didn't you just do a 3s-ge or 3s-gte swap?

Du bist der mit den Ultraleggeras, der öfter mal auf dem Eurospeedway unterwegs ist, stimmts?
(Not relevant to US-habitants... i apologize for writing german)

Holy hell!!! Is that massive intercooler really necessary on a 7A?? How much boost are you planning to run?

amazing job...

Sieht gut aus. Wie viel kW sind in planung?

Joa der bin ich
I'm not a big fan of the 3S-GE(except BEAMS ) and i dont want to swap the whole engine. The 3S-GTE is without a doubt the better base for power but i'm not looking for that much and 7A-FTEs are very rare in germany..



Absolutely not , for some fun on the streets a much smaller intercooler would be enough, but i will use the car for trackdays and ~15min full throttle ask for something that is able to take the heat and release it fast enough, i think the Evo intercooler is a good choice for this job.
I don't plan to run much boost, 8 or max. 10psi on the track, the 7A may take more in daily driving with only short boost attacks.. but a racetrack is something different.

I have a small water to air that sits in the bay and it is awesome. But I also daily drive the car, I don't race it on the track. Although I'd have to say it would probably do better in longer and harder running conditions like highway or track use rather than around town or at slower speeds, reason being the increased amount/cooler air getting to the heat exchanger mounted in front. Water has a better cooling ability than air which is subject to the outside temperature. The w2a itself under the hood is ice cold after a highway run in the summer.

most efficient mounting of an intercooler to date. nice job.

that would block the air to the radiator, yes?

x2, wont the trackday benefits of the intercooler be offset by the fact that now your engine will be running alot warmer? i imagine the cooler air charge wont matter thing when the cylinders are surrounded by a piping hot water jacket 0.o

not as much as your AC condenser does.


um, no.
First, your AC condesor blocks air flow to the radiator more than anything. It's bolted directly in front of your radiator and are your cylinders surrounded by a piping hot water jacket ? nope.
Second, both the condensor and that IC have fins (just like a radiator) and air passes through them, hence cooling the coolant or air you have running through it. With his IC there is plenty of room for air to get through and around it to cool everything just fine.

Plus he has fans...



great 7afte build so far!!!Isnt 3" exhaust a lil big for a 7afte?

haha you're right, completely forgot about the condenser
dont the cooling passages run between the cylinders? maybe waterjacket isnt the right term... ill check out what my haynes manual has to say


either way back on topic, nice setup

Header is completed and the rest of the exhaust will be done this week.

thats some CLEAN exhaust work there

awwwww a cat wheres the fun in that?

Gotta love that German Engineering

do you plan on not using the fans anymore ? it looks like it's going to be a tight fit....
I would of suggested putting them or at least one on the opposite side of the radiator but with that IC and the big horn there, might not be much room there either.

also, get a new radiator. Yours looks about 14 years old and with the excessive heat from that set-up you'll kill that one sooer than you think.

I'll try to fit the stock fan on the other side of the radiator, if that doesn't work i'll get one or two Spal fans. They're much thinner, should fit without any problems.
The hot side of the turbo will get a heat shield, the header maybe too but i'm not shure about that.

It will work for sure
