I have a 99 ls longblock, and i need parts for it and i was wondering what year parts i can use such as

oil pump
water pump
ecu
injectors
iavc
etc
intake mani
exhaust mani

Will i have to use all OB2b integra parts or can i source these from older integra?

SpankedYA!

The engine parts should work 94 and up.

do i have to work about what year injectors i use with the obd1/obd2 thing?

Nope, both are 240cc saturated injectors, so you'll be fine switching between the OBD1-OBD2 injectors. Both the same.

Thanks for the help guys!

Is there a big difference between the 90-93 ls longblocks other than the fact of different obd generation and the dizzy and injectors? I was always told as far as the blocks themselves go, they're all the same. Of course, i pretty much stick to studying the d-series still

I think that the cams are different.

i missed the interchangability part where you mention your current car.

Racintweek

90-91 130hp, tiny intake manifold, small cams, FITV on t-body, peak and hold inj

92-93 140hp, small intake manifold, small cams, FITV on manifold, saturated inj

94-01 142hp, big intake manifold (relatively speaking), big cams, saturated inj

92-93 uses a bigger alt belt than 90-91
92-93 and 90-91 use different clutch discs

please correct me if im wrong but i believe the 90-93 and 94-01 have different head castings, the 94-01 having a little bigger ports, but are interchangable either way

i believe there are other differneces between A's and B's(not relating to the longblock), but i dont want to post incorrect info

what parts do you need for it?
