mtcookson Posted March 26, 2006 Share Posted March 26, 2006 a gt25r is quite small and 1.5 liters is within its opperating range. TTZ guys upgrade to larger turbos that than and i'm sure they spool up quicker than 5,000 rpm. something couldn't have been right. Quote Link to comment Share on other sites More sharing options...

desert dog Posted March 27, 2006 Share Posted March 27, 2006 OK, my two cents... I apologize for the earlier rant, but discospud is a ricer term in my book. Honda drivers use it all the time... GT28's are an upgrade from the modded T22's that are used in '90 to '96 Z32TT's. A lot of them have been installed on these cars. The GT28 is a very nice size turbo for 1.5 liters displacement. They should easily boost to 20-22 PSI. Just make sure you have big intercooler capacity. The other turbo that should work nicely is the PE1420 (Power Enterprises). A friend of mine has a shop in Jersey that can get you good prices on turbos of this size.

BLOZ UP Posted March 27, 2006 Author Share Posted March 27, 2006 The Mitsubishi 16G's look like a better (and waaaay cheaper) alternative to the GT28's, although they would be my second choice so far. Hmm, now that I look at the website, the GT2860R 55 Trim looks nice! Well, at least I have a long while before I have to make the decision.

mtcookson Posted March 27, 2006 Share Posted March 27, 2006 Holset HX25... I just bought one and the exhaust housing definitely looks small enough for 1.5 liters to spool pretty quickly. I'm planning on putting it on a MR2 Spyder (1.8 liter) and it should work out pretty well. Going by Holset's specs, it should support up to 360 hp. Two would be a blast. They're a bit hard to find but are rather cheap when you do find them. I picked mine up in perfect condition with no shaft play at all for 245 shipped... it'll support as much power as the GT28RS for nearly a 6th of the cost. Definitely can't beat that.
