Re: engine transplant...?
How about you get something a little more exotic? Im pondering a 1UZ-FE (4.0L Toyota quad cam 32 valve jobbie) stock there 260hp/201kw). Been reading a few reports on them, and they are a fantastic design, beat the Ford & Holden engines hands down. There built tough! they handle power without flinching.
Change the exhaust cams, and you looking at a 40hp jump in power with no other mods. Then give the heads a bit of a tickle, port match the manifold, have a custom made twin throt upper manifold made up, and a set of 4 into 1s. For a small outlay your looking at a nice 350hp package fitted to an auto.
You can buy the engine/box for $1100, wire it up to a delco and tune it, a few grand on the above mods and you will beat a lot of cars easily. probably get it built for about 5k give or take.
Something to ponder...
