turbo choice
 

Okay, my manifold is almost done and I'll be bolting up the turbo once again, but I'm debating about which turbo to use. I can stick with my t3 from a merkur which has a compressor ar of .60 or I can switch to a toyota mr2 ct-26. I'm not too familiar with these toyota turbos so can anyone help me out. Thanks. Oh yah, I'll be using an in line fuel pump and 5:1 fmu for fuel.

Well on D-series and B-series, the Ct26 turbo is a bitch to use, since the o2 exhaust housing aims the downpipe directly at the block (if I remember right) now, you maybe able to use it since your putting this on a h22 correct? I think I saw your manifold, you aim the flange straight off right?

As far as the turbo being good for your engine, I dont see why not. People claim these turbos can produce 300hp.

And if you need someone to buy that meurker xr4ti turbo, let me know ;)

yah, that was my manifold and it is on an h22a. I will be using a copy of the fmax manifold for a prelude but I'm just wondering what turbo would be better for my engine. IMO, these two turbos are quite similar but I have not worked with a ct26 from an mr2 before. Which one do you think is better for the h22a?

Re:turbo choice
 

also look for 300z turbos from the 86-89 years, and GNX/turbo regal turbos

they all have 60 trim turbos with .63 ar compressors and either .48 or .63 stage 1 turbines depending on the model (so basically the same specs as the merkur)

Re:turbo choice
 

Are you sure the 1g 300zx's turbo have a 60 trim? I had a JDM one, and I think the ar's were .48 and .42.. very small turbo.

Re:turbo choice
 

Since we're speaking about trim, can someone give a little information on how to find out what your trim is. And what "A/R" actualyl means and it's effect to the turbo?

Currently, I have a TD05H from a 92 Talon TSi. I've search Google and what not, but can't find any "specs" per say, about this turbo.

Re:turbo choice
 

Yeah, the 1g 300zx has a .63 A/R on the exhaust side. I am currently running one on my saturn.

Ok, then... I definatly know that turbo was not off a 300zx. It was at a JDM wholesaler, and it just said JDM vg30, so maybe it was off another turbo car over their, but the turbo was soooo small.

Re:turbo choice
 

its a .63 ar on the intake side as well on the 86-89 t3's with 60 trim compressor

the exhaust wheel is a .63 i just had a guy check for me the other day, he looked inside the exhaust flange and it said .63. according to the wheel size he gave me its a stage 1 wheel turbine. so if you wanted any old .48 trubine housing will bolt up if the .63 spools too late

Re:turbo choice
 

so..........I take it nobody knows much about the ct-26 from an mr2 and how it compares to the t3 from a merkur and how it would work on my h22a? hahhahahha ;D ;)
