CT26 turbo

[hdj81v]

If the turbo that "came from a 13bt" has 42010 on the turbine housing, then it originally came from a 7MGTE. Dont waste your time using that exhaust housing (boost at well over 2000rpm). on the other hand, the comp side, if still orignal on that turbo, may have the 45.5mm compressor wheel (inducer). In that case, find yourself a 58020 exhaust housing and you are good to go.

Are you doing this for fun and experimentation or trying to save the $? Reason I ask is that to save $, stay with the toyota stuff, dont go messing around with revised oil line kits, adaptors etc etc which add to expense; not just now but later with potential reliability issues.

Cheers

Just for fun and experimentation, im currently running a t3/t4 but its laggy boost starts to build up at 2000rpm, i wanted it to boost early like 1200-1300.

hdj81 v... I'm in a similar situation to you. Just about to start a freshening up of my 1HDT in my 91 HDJ81. When I do I want to upgrade the turbo as well. No need to build a racing truck but I want more power across the RPM range without breaking the bank or using one off hard to locate parts. The lower the boost comes on the better. From what I've read into it so far I think the Supra mod may be the way to go. I would like to hear from someone how it compares to stock at low RPM though. It would seem that Graeme make the baddest turbo out there for the 1HDT but I'm not sold that I need that. Have you found any good info on real world reviews of the Supra upgrade?

OK, well here is a fellow who has posted exactly what you are looking for. Compares the Supra comp wheel mod to stock and then to my Grunter
