Standard Turbos

[Daron]

I bought my Turbo Mr2 on a K plate, and my mate has his on a J plate. He has told me by looking at the engine that his turbo is bigger because it has some numbers on it that mine doesn't something like T22?

Is this correct?

[Bibbs]

think it should be a CT26 or a CT20b .. something like that ..

[Bibbs]

and one is in the rev1/2 cars (up to about '94) and then the other is in the Rev3+'s ..

Both your turbo's should be the same .. T22 is after market ..

A T88 is a masive Greddy .. maybe a T22 is a tiny one ..

10-4 buddy, ill have to get me torch out and start prodding stuff for numbers

I assume the only place to find this out is on the turbo itself

[Bibbs]

yup .. stand on the passenger side and look at the turbo - it's then obvious ..

Hmmmm...Iv'e never heard of a T22 turbo?? CT26 from 1989-10/1993 the CT20B from then upwards. I'd be intrested to know what it is though.

I recon a T22 is 25% of a T88 ..

:P might be a nice little upgrade then :)

Why not just get the T88 !! and use it a quater throttle

There isn't a T22 turbo, there is a T2 which can be found on Renault 5 Turbos, a T25 which can be found on Fiesta Turbos, and the more common T28 which is used on Skyline GTR's, Pulsar GTi-R's etc.

The T28 does have a larger compressor wheel than a CT-26, however the exhaust side is even more restrictive so it wouldn't make a good swap. Also being a single entry turbo you would reach 15psi by around 3800rpm.

Out of interest a T88 wouldn't spool on an MR2 until around 6500 - 6800rpm.

Toyota CT-26 and CT-20b turbos will fit both early and late cars, so if you are on a budget a used CT-20b in good condition would make a nice mild upgrade for anyone with a Rev.1 or Rev.2 car. Remember the extra power isn't coming from the larger compressor, it's because the turbine can flow better on the CT-20b.
