Fantastic. Good to see you are still active. I miss my 7A.

have you any videos of your car on track?

No, nothing from a 1/4 mile and no circuit videos with this setup, but i wouldn´t try it with this setup right now, on a circuit i´m pretty sure something would overheat with the stock cooling system .. and for a 1/4 mile i would need some better tires and would have to rebuild the transmission, everything looked ok when i took it apart but it´s really hard to shift over 7000rpm, no grinding but the gears just take long time to go in. I´ll rebuild the synchros from 1-4 in the next months with new oem parts, i hope it will make a difference.

But i finished my new intake manifold and it´s huge... made a massive difference in my VE map, the old intake lost power from 6000 to 8000 in a almost straight line, now it stays way longer at a higher level, i gained over 10% at 7500rpm.

Damn. That's awesome.

New year, new turbo... .. i initially wanted to get rid of the totaly useless internal wastegate of the GTX, it just can´t flow enough to be able to control the turbo, so i was going to replace the T28 exhaust housing with a nice v-band housing but since this is somewhat pricy i decided to spend a little more on a completely different turbo that already comes with a v-band housing and has more potential. I decided to go with a G30-660 AR.61 in combination with a Tial MV-R ... maybe a little overkill on the wastegate side but it´s perfect to reduce boost in lower gears.

Before i swapped the turbo i went to a dyno with the GTX and made a little over 400whp and 350ft/lbs @ about 28psi.

G30-660 vs GTX2867R GenII, the G30 is a really compact unit





Fitting the G30 to the engine was quite easy, i just cut off the T25 flange from the header, put the v-band flange in the same position and everything looked perfect, even the inlet fit without any modification, i just had to rebuild the oil and water lines.



The wastegate on the other hand took some time.... but i found a nice position and i´m really happy how it worked out.







The G30 of course spools a little bit later then the GTX, even with the small 0.61 exhaust housing, but when it´s at about 15-16psi it almost immediately jumps to 26-28psi wich feels really funny
The swap was definitely worth the money, at last i´m able to control the boost without crazy overboosts, the car feels way better with this setup. I use a 4port Mac valve for boost control which works amazing, the wastegate is running a 7 psi spring so i have plenty control in first and second gear.

a fantastic project , how did you install the coils on plug ?? what material are needed

[Manu_GRMN]

whaooo good project, you have a diagram to put the bosch p65 coils and what material is needed

[madk4speed]

I decided to completely remove the old ignition system and build me a coil on plug system. I will use a Avensis 7A-FE distributor as crank angle(24 instead of 4 teeth) and sync pickup. The coils are from Bosch (part#: 0 221 504 024), since they're dumb coils withouh build in igniters i have to use an external (part# 0 227 100 211)
Those coils fit quite well, the only problem could be the hood since they're connectors face in that direction ......

Can you let us know on the P/N of the distributor? I am looking the Toyota parts catalogue online but I cannot find it. Is it a distributor indeed or a Camshaft sensor?
