does anyone know where to find compresor maps for toyota turbos?

I have access to a free turbo off a mk3 supra (ct26) or off a mk4 supra (ct12 I think) but I want to see the compressor maps..

I think the mk4 turbo will be too small and the ct26 I have heard is not an efficient turbo...

the other thing is where in the world could I find flanges for those turbos?

TIA

 

Hey, I just bought a Toyota CT26 off a '90 Supra from the yard myself. I can sure use the infos as well. I want to put this turbo on my 95 Civic Ex. Looking for a manifold that will work w/ this turbo as well. Is this turbo pretty good? is it too big for D16z6? Can sure use some infos.

 

there is definately not a manifold that will work.. it is going to have to be custom made, but that cant be done without flanges... I have the toyota manifolds, and I guess I could technically cut the flange off, but it is cast iron and most people say it cant be welded

 

buy a hx or vx exhaust manifold at a junk yard for $10 and ask a muffler shop[ guy to make a plate with 8 holes. 4 holes matching manifold and 4 holes matching turbo. or just 4 holes matching manifold and wel it to the turbo. i had to do this for my audi KKK turbo...just look at my avatar...see the plate?

I don't know if your 4 cyl will spool a ct26 or not. it spools up slow on my 90 supra turbo. thats a huge turbo. I guess the compressor map will help you. do'nt know anywhere to find it though. sorry.

 

i had a ct26 or ct46, i forget which one , but from all my searching i found out it was from a celica alltrac, and the guy told me he took it off a 90 or so Supra? i dunno , i was gonna use it , but it was tiny as hell . i was told it wouldnt work very good for my high revving car.

 

my supra spools pretty slow too, but it is an auto and I had the hot side clipped when I upgraded it, so I was figuring a stock one on a manual tranny might spool ok

 

If you can get a turbo off of a toyota all trac or the 91-95 mr2. It is a ct26 like the supra but it is twin entry, it spools up a lot quicker.
