CT26

[S13 240SX]

the turbo ct26 that are on stock old mr2's and supra's? how big are the turbo's? whats the trim size and a/r? I tired searching and I found nothing about the turbo's

[fabio420]

my friends have them in their car and I believe the stock trim is 57 with a 60 a/r compressor and a 52? a/r turbine. Seem to leag on the old MKIII supras

They were stock components on the 3sgte MR2 (MKII). This turbo was good up to around 325ish on the 3sgte. Seems like one guy made 350...Hyde. That's the guy. Do a google for JekylandHyde racing. You'll find a pair of pretty impressive MR2's.

Oh, by the way, the flange is NOT T3/T4, and they have a divided tang turbine housing. So, you'll need to have a manifold made to match the divide and flange.

well for a mainfold I want the JGstools.com log manifold, will that work? and plus what kinda results will I see if i do use a CT26 turbo and run 7psi for a while? will it get me near 220rwhp and a decnet amount of torque at the wheels? thanks guys.

You shouldn't even bother, to be honest, if you're not going to use a manifold designed to run a divided tang turbine housing. You'll suffer from decreased flow by using a manifold with a big open single outlet trying to go into two smaller, divided inlets.

The turbo is good for the power you're trying to make, however. I'm not sure if it's acheivable at 7psi on the setup you're planning to run. You might end up having to run more boost to overcome the design flaws in the system.

okay well thanks... I was either gonna use a the ct26 turbo or i was gonna go big and use a Holset HX35W dissel turbo, what do you think about the holset turbo, and with the jsgstools.com log mainfold kit?

[KATwo40]

Not familiar with that turbo. Have a map?

[S13 240SX]

No can't find anything on about it really but i know its a big turbo.

holset i say hell yah i 've seen kadet 400whp at 20 psi on that big *****

[Frozen240]

I saw a 2.3l mustang with the holset turbo, he was making over 400 hp out of it. For the size of the turbo he claimed to have quick spool up. I've heard good things about the turbo from Volvo guys as well. You might find more info about the turbo on turbobricks.com. They should be readily available as they are the OE equipment on Dodge Cummins powered trucks.

thanks Frozen240, i will try that link and see if I can also find the trim size, compresser size, and the a/r. If I can't find it i'll post back.

[S13 240SX]

ahh man yeah I still can't find those specs that I am looking for on the holset hx35 turbo's.

[hannibal]

ive never seen a holset map before. I dont think they make them available.

Here's a thread about the HX35http://forums.nicoclub.com/zerothread?id=75732

I think I'm gonna go with that turbo!!! and now since my one buddy said crap about that turbo, now it makes me really wanna get the HX35 turbo so i can blow away his t3/t4 turbion. hahaha

DSM WERE TALKING ABOUT THEM AWHILE AGO ...GOOD TURBO ALMOST THE BEST FOR KA ALMOST SAME AS GT30R FLOW CAPABILITIES/SPOOL

[racin-type]

if your still interested I have a CT26 turbo from a MKIV Supra with 50k miles. its the secondary turbo from that engines sequential turbo system. The secondary turbo is a bit larger than the primary turbo. The person upgraded to bigger turbos.

email me at [email protected]

imho if the holset is similar to a GT30R then its way bigger than you need since your going for around 250rwhp. Also alot of people have different opinions on how fast a turbo spools.
