ct26 question - Toyota Nation Forum : Toyota Car and Truck Forums

I always thought the ct26 was a cheaper turbo built for quick spool and low boost.(right around 13psi max) i know this is a 2nd gen with a full 3sgte swap but my thoughts are just towards the turbo itself. Could his be a rebuilt? cause hes running 16psi it says and thats a little overkill for that turbo.

I am definitely a noob when it comes to F/I but i was just curious and it has been on my mind for a few days though.

Just wanted a pro to clear it up for me. Ive been startin to research alot though about the 5sgte build and may be thinking of starting to piece some stuff together after this summer though. This summer is based on a paint job and possibly 5 spd swap which i know im going to do before i even think of a turbo.

p.s. I am liking his turbosmart megasonic bov

well you can always upgrade the ct26, but the ct26 from what i read can push more psi but the only thing is that the pressurized air gets hot quickly when overkilling the tubo, pkus you overheat the bearings aswell...mr2oc.com have alot of info on it

16 psi for the the CT26 is pretty much it's max. After that, it " runs out of breath" and is out of it's efficiency island. Like stated above. the boost charge just gets too hot and the turbo is over worked.The turbine becomes the " bottle neck" and can't flow all that exhaust.

oh okay thanks guys and thanks bird ill look at that after i get home tonight! =] i was just in question so i thought id ask

I'm by no means an expert on turbocharging, but if you're looking for 16psi or more, why not a T3/T4? They sell adapter plates so you can bolt it to the 3S-GTE manifold.

agreed with jedi. after 15psi the ct26 just pushes in hot air and doesnt do anything at all. does anyone run a 20g's on toyota's at all? if so thats one i reccomend.

EDIT answered my own question:

im not planning on 16 psi lol. Im only planning on running 10 maybe 12 tops but thats pushin it. lol only reason i made thread was questioning the ct26 i was always told they maxed out at 13 psi but i guess my sources were wrong =p

Well, they may have mistaken the fact that on the 3sgte MR2, Toyota put in a fuel cut that kicks in at 12 psi. Not sure if the Celica Alltrac does too- but it's likely.

aren't ther 2 types of ct-26 turbos?
3sgte twin entry and the 7gte single entry?

from what i remember the 7mgte center and compressor fit on the twin entry ct-26 exhaust side.
