ok, so been searching through the vast multitude of posts on this site, and it's pretty much left me with more questions than i started with :S and since there's nothing like having your own questions answered personally, i'm going to aska few, please don;t flame me 2 much
ok, so i have an hr30 skyline which has an l20et under the hood (05l head, not sure on block)
in my bedroom i have a complete l28 of the n42 variation minus 1 rod :S
the goal is l28et pumping out 300rwhp
from what i understand, compression ration on the l28 is around 8.5:1 am i correct? this would be a fairly ideal compression ratio for turbo? will there be any advantage going for aftermarket forged pistons and rods, considering my power goals, and the cost involved of either importing some or getting somthing made locally? (there are practically no aftermarket parts for L series engines in nz)
now the l28 has a bent rod, are the l20et rods the same? stronger? weaker?
from reading the forums, seems getting the bottom end balanced is the way to go. i was considering knife edging the crank, but again, with my power goals in mind the the cost involved, is it worth it?
now the head. i have the l20et head, which has 05l stamped on it, and i have the n42 head. which is gonna be the better base to start from, and will the l20et head even go onto the l28?
porting...again, is it worth it for the cost involved?
cam, whats the ideal cam grind for an l28et? (really want a lumpy idle but prob not idea with turbo setup?)
not gonna sak questions on the bolt ons side of things till i've sorted out the engine build. the engine will be built with all new bearings, rings seals ect.
cheers guys for all your knowledgeable advice, this is one great forum keep it up
