Well, with either car if you do it right its going to be extremely expensive. However, none of these are set costs, as if I REALLY wanted to, I could have made my own subframe, which would have only cost as much as the materials (say $300, though likely a lot less), use the stock ECU, ignition, fuel system, cooling system, etc, and probably had the car running for well under $5,000. However, it would be more work, less powerful and most importantly less reliable in the end.

To get a 20b ported with the twin turbo setup (I believe) w/ subframe and spindles from RX-7 Specialties, it would be $8700. Not a bad price!!! This also includes 3mm apex seal upgrade and whatever else they usually do when doing all that "good stuff" to make an engine better and like brand new...I'm talking about like race/high hp prepping. I'm going this way when I'm ready to swap. Just got a new 13b though, so it's going to be a while. Their site is down right now for some reason, but at 12-13 p.s.i. with just those basic remanufacturing mods, it is pushing 550 hp!!! Great deal I think,

$8,700 scares me...

It ought to be 10k at least.

yeah but see, what if you have all of that ... then you want to go 20b. Then its just the cost of the engine and the mounts.

Jeff20B

You're right.



Hey, do you think you'd break even if you were to replace the heaviest 13B ever made (REPU options like 9 bolt flywheel etc) with a stripped down 20B? Weight-wise, not money-wise lol. Pennywise?

I'd like to do a 20b in a few years, when this new engine goes. By then I should have everything i need to just drop in the 20b.



But thats wayyy down the road
