Turbo Questions
 

hi there, i own a 1988 Rx7 Gxl, (13B)
i was looking into putting a turbo on, but i cant afford a new one truthfully so im down to what kind of one can i pull of in a wreaker.... and look at getting rebuilt at a latter point in time.

what specs should i look for in this turbo?

these ones should be easy to find (2.2L turbo's)
which one is the best/ should i look at another one?
i will pull everything needed for this swap out of the car, and just transfer over...
let me know my best choice....:-( sorry for being broke. lol
thx

without a rebuild on your engine ide say go with the stock TII turbo, you dont wanna over boost the old n/a engine anyway, youll probly end up tossing seals. plus like aaron once said, mazda picked a great turbo for the rx7.

jsut if you didnt know, i turboed my n/a. i used the stock tII turbo and mani.

Man... I dunno. I would suggest NOT turbo'ing your N/A if you don't have much of a budget... I suppose you *could* ghetto-rig it, but is it worth it?

You should save up for a good turbo, EMS and all of the associated goodies before going turbo. You won't be disappointed if you go 'this' route, but it's likely, that on a short budget, you could run into some things that you might regret cheaping out on (if you go the "budget-less" route).

Just a thought.

You should really find something with a bigger exhaust like a .85 or around there I had a 60-1 to4b on my n/a worked fine but mine had a 1.15 hotside on it and it would lag.

How much are you willing to spend?
How long can you afford to have the car not running?
Who is doing all the work?
Did you read the FAQ and the stickies?

None of those turbos are even close. Just looing, all the A/Rs are WAY too small. Compressors are also kind of pathetic. :)

Really, you need to check the FAQ and archives.
