for someone with an EMS on their vehicule and a good basic acknowledge of tuning, those courses make a lot of sense and are not pricey at all.

just to tune your frteshly installed EMS will cost you around 700 depending on the tuner / shop you go to.

That is crazy...I had no idea. This is why I'm researching a few years ahead of time...thanks man!

Now, would this also be necessary on a 3S-GTE swap?

Well, my mechanic/tuner refuses to have an engine blow because of detonation. He's too proud and people here talk smack with a quickness if you screw up. He doesn't trust a piggyback, so he went really rich and safe on my tune since I'm on stock internals. The timing was retarded to like last year, LOL, and I still made good power. He said that with forged internals and the Microtech LT10s, which is what he runs in his car, he will feel safe and be able to run a leaner mixture and also not retard timing so much. Right now he has the fastest MR2 in the island...with a stock head to boot. He knows his stuff.

On ANY engine. And yeah, tuning is expensive. Here in the island the cheapest I've seen is $300, which is what my tuner charges. He charges less to me because I helped him with something when we met, so now he gives me good prices.

Alright. Well, I guess it is money well spent. I know you did two turbo setups, and a tune for each I'm guessing, so do you think you would have spent less than a 3S-GTE swap if you had done only a single setup and single tune? Without any mods not absolutely necessary to turbo'ing, of course.

>Hafkai, another question...you're running the stock transmission right? I'd like to do a manual swap before I turbo, and I'm wondering if the ST's C52 (?) will hold the power, or if I should just get the GT's S54.

Yes i have a stock C52, the tranny seems to have no problem with turbo power. I only got some problems with my synchronizers but thats due to the harsh shifting on the track.

Btw... i got a little winter project..

I just test-fitted everything to check the clearance, seems to fit with the 16 inch wheels.

what are the specs ( offset specially ) of your wheels ?

I have the same brake set-up but I needed 15 mm spacers to clear my wheels.
what disc did you use on your set-up ?

I used Cadillac catera

Hafkai

#69

The wheels are 16x7 ET35, the brake discs are stock Toyota parts for the ST205.

Hafkai

Another Autobahn video , this time at about 12psi, the boost drops a little bit over 5500rpm and i think the T25 can't give much more than this at top end.... but i'm pretty happy with the result.

100-200 km/h

Got some new injectors.. SARD 650cc/min



The reason for those big injectors is E85, i'm still tuning the e-manage but so far the engine runs really great with this stuff.

some of the guys on mr2oc have been having great results with E85, hope to see you have some too!

Keep us updated, man. I'm no longer in the 7A-FTE game but I will never lose my love for the engine. I still have mine sitting in my garage. I don't want to sell it. I want to install it in another car.

Is there anyway to make the synchronizers stronger?

I don't think there is some way to make synchronizers stronger, the only way to prevent them from getting destroyed is to shift properly ...

After over 1000 miles on E85 the engine still runs great and i completely retuned the E-manage to use the possibilities of this fuel.
2 weeks ago i went to the racetrack for the first time this year and with ~10psi boost instead of 8psi like last year. I really love E85.. no knock and the engine stays a little bit cooler than with regular fuel, perfect for track racing.

I currently boost about 12,5psi with my daily drive setup without problems but i won't go any further before the engine got rebuild.

Some h-beam rods that i already got, Wiseco pistons (9:1 compression) and the basic stuff to rebuild an engine .. and maybe a GT28R turbo if i got some money left .

How is the pull with the 650cc injectors? Does that turbo only hit like 15 psi max? Do you have a write up on some of this besides what you have as a part list in the begging? Have you tried pump gas with those new injectors? Sorry for all the questions I'm still learning lol

The injectors don't make any noticeable difference, you just got more room left for power and no i don't have another write up.

I did some performance test runs with RaceChrono together with a 5hz GPS receiver, maybe not 100% accurate but it shows roughly what's possible. Max boost was 11,5psi.

>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.

QUOTE (OOBE @ Nov 9, 2009 - 4:21 PM)

>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.

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?

Cheap and good doesn't work .. the e-manage blue would be cheap but not the best choice, the e-manage ultimate is more expensive but you can tune the engine pretty safe. The best way would be a standalone but that would be extremely expensive and hard to tune.

I got some nice parts waiting to get in the engine, hopefully i'm able to rebuild the engine before winter

Hafkai bro,
I've sold my previous 7afte (stock engine, wrx td04-13t, emanage blue, Ron97) to my friend. On my hand, im boosting 1.1bar for 2 years and now with him another 2 years. So far no issue except head gasket burnt once.

now im going to go for it again except with IHI Vf35 turbo and standalone haltech sprint 500. Will push to 1.3bar and see how it go. since you're going to rebuilt, why not push it to max?

Hafkai

#87

Sadly it's to late to push the stock engine to max .. last week a rod bearing failed, now i got a broken rod and a big hole in the block..... looks like a oil problem. I already got a new block and most of the stuff i need to completely rebuild it, i just need new bearings.

But the engine can handle a good amount of power without problems. I was trackracing the last 2 years with the turbo, this year with about 230HP and over 300Nm, i just should have changed the bearings

#88

I had my old 7AFTE tuned to the limits on OEM internals as well so this project is for me real nostalgia... I hope your car will be running again soon and luckily we meet in Poland on Pan European Celica Meeting next year.

After taking the old engine apart i found out that the bearing wasn't the cause of the thrown rod, it looks like the spark plug overheatet extremely, the electrode began to glow and i got the worst of it all... pre-ignition. I'm not shure what caused the plug to overheat, i don't think it was a fuel problem but i will let the injectors get checked.

Here is a pic of the spark plug and some of the rest of the engine:









The new block is getting machined this week and a new cylinderhead is allmost done, i just have to polish the combustion chambers and finish the ports.

wow that plug looks horrible but im glad ur continuing the build
