you cant squez any engine into the engine bay, it's so SMALL!!!!

if you want the power, get the turbo charged and do a swap, they only cost around 800 for a reasonable one.

get a boost controller, with pod and full 2.5' exhaust, plus a supra intercooler, on 10psi you can get arund 90hp on wheel, but you need an additional injector. no cam oe internal touched.

but a cultch upgraded is need soon, and it must be a heavy duty. plus some 14' rim and good tyers.
