Hi all, I am rebuilding my ct20 and found this on ebay: Billet Turbo Compressor Wheel TOYOTA 2L-T 2.4L CT20 17201-54060 (42.1/64.9) 6+6

It has larger inducer and exducer diameter and the seller told me that "This billet wheel with higher blades than stock wheel. It can increase more air flow and increase hp".

Anybody has any experience with kinugawa or done someting similar? I am also doing a full 2.5" exhaust and thought that it would be a nice match to have a higher flowing turbo with the bigger exhaust...
Thanks for any input!

Yeah I keep reading about the hybrid ct20 which uses the compressor of a ct26 but that needs some grinding of the housing... i was just wondering if i could see some gains with this billet wheel.
 
Honestly I think a stock 1hd-t wheel would suit you're turbo as an upgrade...

The old Gturbos were CT20 turbines with supra cold ends....
Now they are Basically a TD05H 1*G
Good luck, make sure the bore size of the wheel you buy fits the turbine shaft size.
 
Would that be a direct fit? IIRC 1hdt ct26 wheel is 43mm, same as the kinigawa one featured on the listing. If it can fit without modifications i can get a hold of one easily!
 
What ever you do make sure you use a dynamic seal when you put it all back together. They come stock with a static seal, I replaced mine and the spool time was noticeable.
 
I'm sorry Postoy i'm not familiar with this dynamic and static seals? You mean when i reassemble the turbocharger? I'll probably have a pro do it, i'm just asking if a compressor wheel out of a 1hd ct26 will fit in the ct2O housing.
 
if you are going to buy any complete turbo set up I highly recommend you getting the turbo checked out by a reputable shop and have the assembly balanced for piece of mind.
 
Yeah I'll do that for sure since i'm getting the turbo brand new for so cheap! I need to find a flange adapter and the correct oil and water lines..
 
I'm looking forward to seeing how this works out.

It's amazing how decent the stock CT20A is too though. I've been running mine hard for the last 1.5 years. 17psi boost from 2200rpm to redline! Through an intercooler too, so that is a lot of air. It is a relatively big turbo for the small engine, and can move a lot of air. I know other people getting 20psi or more from the stock turbo without an intercooler.
 
It's not that I want a more powerful turbo (more psi) but a more efficient one that starts spooling sooner. I have a fmic that involves some piping and that's causing lag.. i also have a brand new water injection kit (shurflo pump with boost activated solenoid and do1 injector).. i haven't installed that yet, if i'm happy with the results i might ditch the new turbo route.

Yes, more efficiency would be nice. Turbo technology has come a long way since the 80's. Well, let us know how you end up going. Sounds like you've got a nice truck.
