My brother gave me an old compound turbo that he said came off of an RX7, but all of my research said the RX7s came with 51/57mm compound turbos, and these are 35/38mm, for a free turbo I cannot complain, but would this be worth it on a 1.6? Would it make anywhere near 200hp?

edit*
I am planning on ARP head studs and forged pistons and conrods if i turbo it

 

Never build a turbo setup around a free turbo. I'm not well versed on that particular RX-7 turbo, but I know that much. You'll spend more money making a custom manifold and downpipe than you would just buying a T25 turbo for any of the T25 manifolds out there.

 

I understand where you are going, but hypothetically, are 35mm turbos even gonna push 170hp?

 

Here's one that'll do 250hp supposedly:

It really depends on a lot of factors, not jus the compressor wheel size. It'll probably spool crazy fast and run out of steam above ~5000rpm. Most people don't appreciate a power band like that.

 

thanks for your input, I probably would have had so much frustration with the compound turbos set
