I just scored a k24a4 (160hp/161tq, 9.7:1 compression). I could change pistons, head swap, intake, and make maybe 240whp in my Miata N/A with that motor...or I could just continue to run my BP w/ 2560 turbo.
So right now, my car gets about 29 mpg driven to work, and it should run low 13's in the 1/4 with that turbo...I'm also guessing it should put down something like 250whp/220wtq?
How would the k series Honda swap compare to what I have now? I'm all about a cleaner engine bay, and N/A power...but the lack of torque has me stumped as to how it would feel to drive it.

Your only gonna be around 180 ftlbs with the NA, but you will be loosing weight, and running cooler under the hood. If you have e85 in your area you can boost your power a bit with higher compression (13.0:1 +). I have no experience with how the power feels, but my friend is making 366whp with a k24 on methanol and he says it feels like a turbo car lol

Yup. More than one way to do it, and customers certainly can build their own exhaust any way they want.
I like our solution. Works great, and the real clearance issue is where to put the collector. Since you have to already be at either 2.5" or 3" before you actually come off the side of the motor, its nice to duck it under the pan right away so customers can use the OEM exhaust routing.

I think I emailed you back on this already... short answer is we don't know, but I do know that the K series A/C compressor does not quite fit. We need a test unit from Kraftwerks

Im not sure of what turbo will suit what i want to do though 10-12 psi on 93 pump 375-400whp area. This car is a street car so im praying that 205 tires will save my transmission and burn up instead of breaking ****.
Anyone have recommendations for turbos ?
EFR 7163 + .85 a/r v band housing (twin scroll internal gate ? )
i worry about the gate being to small on these turbos to run low boost
GTX 3071R + .86 a/r Tial housing
most people on k series forums are running bigger stuff like gtx3582 , 6262, big efr's. I feel that these are to big as i want really good spool up and low end and reach the power i want.
