I have access to an LNF engine, so here is what I am thinking:

I would make a Frankenstein engine with the L61 head and crankshaft, everything else would be LNF. LNF exhaust, K04 turbo, and I would get an aftermarket intercooler/piping/intake. Trifecta tune. LSJ fuel rail (or L61, not sure yet).

This sound alright?

 

look up the thread I made involving mis matching motors.

 

Sounds like your title is wrong.... Why do you think that the L61 head is better than the LNF when you plan on running all LNF internals/accessories?

 

if he keeps the l61 head he can use the factory wiring harness
