L20 series engines exhaust changability


Post by Jonesboy2 »

I have a 1982 Datsun maxima ld28. I just bought it and don't know all too much about yet. I was wondering if I could put an aftermarket header on it that is actually for a 240zx. I think if I have read things correctly the L20 series engines all have the same block? I didn't know if I could buy one and it'd bolt right up to my maxima block? And how much back pressure if much at all do the ld28's require? I'd greatly appreciate any feeedback. Thanks in advance and God bless

The L28ET exhaust manifold is not quite a bolt-on, but only a little trimming is required at the mounting flanges. For that reason, I suspect that headers designed for the L28 will more-or-less bolt to the head.

Whether the downtubes will clear the steering box, alternator, etc. I do not know.
