Hello - I am a long time RX 7 owner and currently have 2 1988 13B RX - 7s, GXL and convertable. I would like to drop re-built engines in both with a focus on increasing the HP for the GXL (somewhere just North of 400hp).

My question - what companies, from your experiance, provide a quality product, good advice and a resonable turnaround?

Any thoughts or recomendations would be greatly appreiciated - thank you!

 

first, welcome to the board.

next, it might help you get more specific answers/suggestions if you say which state (and maybe a reference city if you're out in the sticks).

if, for some reason, you feel you're going to want more than that, then you're probably better off finding an actual turbo block and building that. here's a recent discussion that you might find relevant: https://www.rx7club.com/naturally-as.../#post12569127
