CT20B

Postby MARLON1211 » Fri Aug 20, 2004 2:25 pm

this year am lookng to buy a CT20b, and I know this is a direct bolt on. I've heard fom the MR2 guys that this is one of the most reliable and most powerfull than a CT26. And lots of low end torque, and low end power.
Anyone has this convertion and pls give me your opinion on the comparisson on the old 26s to the 20s. For a (ST85). Thanks.

I don't have a CT20B, but I have driven my friends MR2 with the CT20B and a guitted cat and damn that thing spools up quick. It also keeps steady power all the way up the RPM range. Like Zeus says it would be a great turbo for auto-x.

Yes you're right, and it cost way less than T3/T4. I know T's are good and is more high performance but if you're like me with limited resorces like (money). I would like no complication like tuning, manifold, Dp etc to make it work, and assembled right. Besides my goals is not too radical just around 13s, with stock engine, and little fuel mods. Thanks.
By the way never really seen one upclose, just how big is this compared to a ct26.

I do hear one drawback is that no one in the states rebuilds these turbos. So aren't we taking a chance on the how long they last when we get them? i think someone did mention back on the old board that Majestic Turbo can rebuild these. Anyone want to give some info or clarrification on the ct20b being able to be rebuilt and also, info on Majestic Turbo? (might as well, since we have a fresh board heh)

Thanks!

Is the 20B a bolt-on HP upgrade at the same pressure, or is it just going to allow greater performance improvement through other mods. I've heard claims of 30bhp increase just by adding the 20B at the same pressure - seems a tad odd to me.

More efficient turbo will create less heat=more power

I too have been looking into getting one of these for my 165 however out of the two places i called thus far, one of them basically laughed at me, and the second said i would have real problems locating one without buying a front-cut. I am in Melbourne, Australia by the way...

So i have two questions. Have you guys found them hard to come by in the states? And secondly, wll i need to upgrade my fuel system to run the 20b? if so what with?

Cheers
