Does that mean this could work on my Si?

i know the offset is off from stock but clearance shouldn't be an issue. the only problem is the center bore (subaru BBS center bore is too small) does anyone know what it is on these wheels? or if the tsx has similar specs to the Si.
i think this would be a nice set up with 225/45 or 215/45

thanks!

Ok, how about this "problem". And I'll bet only you can figure it out. How can i get race headers on my 2012 K motor? Seems to be a 'problem' because they attached the OEM header to the block or something. Any thoughts on this?

lol.... Bruce... too funny man. Unfortunately the exhaust manifold is cast into the block so there is no way to replace it and thus, no way around the single exhaust port setup and getting a true "header" setup.

The only solution is the replacement downpipe you hear about. Although not as "good" a setup as a true race header the single integrated port is fantastic for placing a turbo on this motor. It's a better solution for FI than NA on this motor. How much power do you want?

The exhaust side of the K24 head is collected into one outlet. For example:


While the K20Z3 has 4 outlets (one from each cylinder) on the engine head:
