Very nice and congrats on making it back home on it's own power. What octane are you running for 19psi of boost and what turbo?

Thanks Suprahero, it's on 93 pump gas on a conservative timing map. The turbo is a T04 60-1, .68 exhaust housing, .70 cold side. Here's a couple of pics of the turbo next to the ct26

Yes, it is the stock R154 with the stock lsd rear differential. I don't remember of hand what the 90 Turbo came with. 3.73? someone will hopefully have the answer.

I wish my 7M pulled that hard! I'm having trouble deciding on a .68 or a .82 Exhaust housing on a custom GT35r. Do you find your power fades or the turbo chokes at high rpms? Do you happen to have a dyno sheet and mods list? Thanks!

I had the .82 on my gt35r and I can't imagine having anything on there that would make it spool faster or come on any more violently. On my dyno pull where I made the 543rwhp on the 1jz, it never fell off until about 6900rpm and he may have been letting off of it then anyways. Good luck.


Conservative timing map? What would you consider conservative? 13*, 14*, I'm just curious about timing maps. I've installed the meth injection kit on mine and I have it at 20* of timing in the higher rpms and boost levels. Thanks.

Your correct, at ~16psi, it's in the 14s, 13s, at 19psi it's even in the 12s-11s starting the 3k + rpms. Since I've yet to dyno tune, we've have not had the chance to do a timing map. I think we are using the default skyline timing map provided by AEM which apparently is a pretty good starting point.

Tekdeus, I've yet to see the .68 housing fall in the upper rpm range. I would think that maybe with a .58 you could see that. That's also with a RonR long runner intake, a Q45 Tb and 2.5" hot side, 3" cold side intercooler piping (if that makes a difference)

I don't have enough fuel yet for that, lol
I doubt my MKIV fuel pump and 550s will cut it.
