ok so now I have 20b installed but seems to be boost cutting @ 14psi.... i read somewhere that the map sensor was only used for the boost gauge and the boost cut... is this correct? doesn't have anything to do the the mapping on the ecu??

but yeah so far i think you were all right with the 20b... already twice as quick as it was before :D

i would definitely recommend getting a second hand ct20b from my own experience, they are a fantastic upgrade for a gen 2, nice and responsive, and they seem to last forever.

i used one on a gen 2 with some other bolt on upgrades and made 192rwkws @ 18psi, it was such a fun car to drive!

Haha, I still haven't had a chance to install it, but hearing your experience again is giving me inspiration to get on with it!

The Blitz ECU however is going well " />

You can still buy the CT20b new from Toyota. Cost is roughly $2400 :)

I'm running a 2nd hand ct20b that dylan(gorilla industries) sourced, you can trust anything that he supplies & he has plenty of happy customers on mr2aus . I guess the reason you cant buy new ones would maybe be because they are a toyota designed turbo & most other manufacturers just source turbos from external companies eg: garret mitsubishi kkk

Yes twin scroll, not exactly same dump but gen2 dump will work. Go ct20b. I hate the ct26 with a passion. Spool is good, falling over well before redline isn't.

yeah defiantly thinking of standard turbos now, so my choice now is between new standard ct26 or 2nd hand ct20... are the ct20's twin scroll? same dump etc..?

A used CT20b sounds perfect for what you want it for. Pretty much instant boost and boost to redline. These will support up to 200rwkw easily with supporting bolt ons.

A $600 China turbo with a 60-1 wheel would be utter crap on a 3sgte. And possibly last as long as your previous turbos.
The 60-1 CT26 works okay on a Supra (6cyl) but not a 3s.

Dylan @ Gorilla industries has a ct20b in stock check out the for sale section of this forum

so you would seriously buy a used unknown condition ct20 over a new ct26 for the same price? sounds risky to me, i cant find any new ct20's anywhere... there must be a reason no one makes them anymore...

Turbo was destroyed due to the oil feed line being bent and slightly crimped, I already have braided aftermarket one ordered.

Why do you keep blowing turbo's, whats actually going on them? Are you rebuilding these yourself or something?
If your only running 15 pounds boost, no use putting a larger compressor, it will just be more laggy. Get a CT20b, will spool faster and is good for 15psi.
