I run 100 octane now 13:1 compression. Never use 91

My previous engine was 12:1 and was tuned on 100 (kinda old 100 actually). This engine is 13.7:1 and was tuned on E85.

I had an 06 TSX moderately modded in addition to my CR. The TSX engine was very responsive to any mods. Nice pic on the swap. Nothing you say will convince me that your S is as quick as the GT4. Unless I can get a ride of course. :)

Hey mate, what have you done with the breather port on the valve cover? The last pic on page 3 shows it left with no hose/filter.

I am thinking of capping this off/welding it closed, and tapped a new fitting on the opposite side so its closer to the rad.

sorry to bump an old thread .. i am about to do this swap and wanted some insight. no one really explains the harness issue. what engine harness was used, what needed to be extended and what sensors added. i know the rywire was used. what ecu ?

thanks op

what did you do to make the ac to work

Wealth of information here guys, thanks!

I heard through the social media grapevine that this engine blew in a canyon run. Is that true? Kinda disappointing.

how much did that put down? We did 293 whp on a stock k24 bottom with a stock port and valve k20 head with a mild cam and an after market intake mani. Motor had a real fat mid range. Alternatively, a stock off the boat k24 did 249whp. With an aftermarket header and intake manifold. All tuned on 91 octane.

how much did the conversion and parts cost?
