Small update... i bought a simple compression tester and this is the result: cylinder 1-4 : 190 | 188 | 187 | 186 psi ... I'm pretty happy with those numbers.

Then i build a scale to measure the corner weights of the car that is able to weigh up to 500kg (~1100lbs) since i wasn't able to find one thats affordable.
Surely not as precise as a professional corner weight scale but enough to get an idea of the cars weight distribution









The only problem is that i only have one scale.... so i have to get all the other wheels on the same height and it takes some time to measure every corner... but im not doing this every month so it's ok

Weights without driver and full tank of E85:

FL 745 lbs | FR 815 lbs / 63%

RL 485 lbs | RR 428 lbs / 37%

Total 2473 lbs

Weights with driver:

FL 813 lbs | FR 835 lbs

RL 555 lbs | RR 432 lbs

Total 2635 lbs

Just finished another little winter project started out with a ST202 rev counter i installed that was a little inaccurate.. searched a way to calibrate it and found out that you can alter the movement of the needle quite a bit. Enough to let it travel twice as much with the same rpms, or the opposite way with the speed indicator.

Doesn't look perfect but it works..



And a short video where i was testing the modified hardware with the old dials.

E85 is awesome, i will try to get some E100 for this season... no more crappy fuel that contaminates the good alcohol .... just a little difficult to get..
And since my 650cc SARD injectors are getting a little bit to small for this stuff i will replace them with some far more modern Bosch EV14 980cc injectors.

Hafkai

#126

New fuel rail and injectors are ready, i just need some fittings and stuff to build a new fuel line from the stock filter to the rail.

that is the sexiest 7a manifold I have ever seen O.O

SwissFerdi

#129

Great looking manifold, and I don't know how I missed it (and nobody else commented), but a center-mounted tacho! (!!!!!) That's fantastic! I love that look. Why the optimistic redline though?

Haha not bad .. and yes the stock 7a got the coil in the distributor, but not my 7a

@ SwissFerdi

And i thought i'm the only one who likes that idea .. i plan to install 266°/256° cams (the only option i got in germany) in the future, therefore the high redline. With stock cams theres no reason to rev that high, thats right.
A video of the tacho with the new dials, it's a bit more laggy than the stock tach due to the stronger spring on the speedo needle, but nothing too bad: Youtube

The new manifold is on the engine, build a AN6 fuel line to the stock filter, no leaks this time... and the engine is running really well with the new injectors. They're pretty loud but thats no problem, idle is a bit smoother and the throttle response seems to be a bit better.

#131

Back on the streets ... 7A-FTE - Garrett T28 @ 1.1bar

Still have to do lots of tuning with the new injectors and my ST205 fuelpump seems to be maxed out... but i have a Aeromotive 340 ready to go in.
But for now i`m really happy how the engine performs.

Pulling very nice there Lot of respect for this Celica with all the work you've done on it

#133

WOW. Good work! Love every bit of this ST! 7ATFE powa!! Ever thought about shaving down some of the fins inside of the intake mani?

Hafkai

#134

Thanks for your comments

@ kormysh8: not really, i don't think this would gain any power at all, the best solution would be a completely new intake manifold, but for now the stock on seems to be sufficient.

I finally went to the track yesterday, i was somewhat nervous and planned only to do some slow laps.... well... that was the plan ....

'94 Celica ST Turbo - Eurospeedway 21.04.14 .... starting behind the ST205 was a bad idea... i just had to go WOT...

The suspension seriously needs a new setup... the car corners like a rwd without the corner exit grip .... very loose rear end, but lots of fun ..
But even with the crappy traction i managed a top speed of 132mph on this track, faster than i thought.

That was pretty good. A lot of tire squealing lol.

Thanks! ... i definitely need a LSD....
The calipers are from a preface 996 Turbo/GT3, the caliper brackets are custom made and the discs are stock ST205.

Mine does the same, I don't think it's necessarily your suspension setup. When the rear of this car is stiffened it just likes to swing a bit, especially in a steady-state corner under trail-braking. I love it.

You were quick mate, very well done. Passed a lot of cars that technically should have been passing you.

Edit - LOL @ at the E30 around 7:30, he was trying so hard!

Well...... crap .....



Always remember to use loctite on flywheel bolts.... btw.. does someone know if there are suitable ARP bolts for the 7A?

I'm not sure if they really got loose and the whole thing rattled itself to death or if the bolts simlpy failed.. but the marks from the bolt heads in the flywheel look like the thing was loose for some time...

SwissFerdi

#139

Scary! Any clutch damage?

Nothing bad, just some scratches.



The worst part is the crankshaft....



I hope the mating surface can be fixed but it sucks to take half the engine apart.... it was running so good and everything was fine, goddamit

Hafkai

#141

I replaced the crankshaft with my old one from the first engine, had to get 2 new main bearings because the crank has different journal sizes and i replaced all rod bearings too. Still waiting for the ARP flywheel bolts and i got me a new clutch since the Exedy Stage 2 was slipping at 1,2bar boost.
The new one is a ACT XTSS, should hold up to 310ft/lbs... the Exedy was supposed to hold 261ft/lbs wich is pretty much the exact torque i had with 1,1bar.

Hafkai

#142

I finally got the ARP bolts (ARP# 203-2802), torqued them to 70ft/lbs (stock bolts 58ft/lbs) and this time with loctite....

ARP compared to stock bolts:





New clutch...



I got most stuff back together, just need to torque the transmission bolts and reinstall the IC piping. The clutch pedal is definitely stiffer compared to the Exedy Stage 2 but nothing to bad.

Hafkai

#143

Well... the ACT clutch is amazing, smooth engagement and seems to hold more torque than the Exedy Stage 2... maybe to much for my old transmission... years of track racing an a lot more power than stock resulted in a funny looking 3rd gear:



I replaced the transmission with a spare one i luckily had laying around, but i think i should start to look out for an alternative to the C52 ...

Man, you've got some bad luck lately. Kudos for not getting frustrated with the car!

Hafkai

#145

Long time since the last post... haven't done much on the car besides trying not to destroy something ..

The only new things are some oil-/fuel catch tanks and a new air filter box, everything build from scratch.

Since my Aeromotive Stealth intank pump died after just about 2-3.000km i put the old ST205 pump back in and let her fill the catch tank, from there an external Bosch 044 feeds the engine.

The air filter box still needs a top cover since it's kinda illegal to run open air filters in germany .... but for now i leave it open, just love the sound ....

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

Where did you find the forged pistons and rings? What model or reference are they?
