you will need the ecu , but easiest way is to modify the wagon harness to mpfi , then make the mods to go 0bd1 if you want you can run vtec on a switch or leave it for the ecu to trigger . trying to mate a different harness to your wagons factory harness will be a head ache but if your savy with the...

seat pan swap is the only way to get a sure fire fit . but with time money and patience you can make anything fit . one of our members has like 10 hours into his seat swap . i believe he used ep3 si seats

marvel mystery oil might help . i have seen great results mostly with v8's . but a valve adjustment would be the way to go . there was a good write up on here i think classic was the one who posted it

thats right i forgot about the input shaft spline count . a older member by the screen name of cougar had some good info on the compatibility of d series trans , ie what clutch , pressure plate combos to use between the 88-91 drive trains

your factory radiator will be fine . the spare harness will help but you have to modify your current one . there are good write ups for dpfi to mpfi conversions . again tho it will depend on what obd you want to run . but it can easly be added to your mpfi swap

the one at the manifold ? or the 2 rings that sit inside of the header were the pieces meet ?
if its the rings i used felpro 60776 but i have a dc header but should be a close match

cable drive d series transmissions have the same spline count . the changes are in the front spindles , 4speeds are different from 5 speeds again its the spline count . so you can swap the trans with out changing axels . if you change the spindles then you need the right axels to match . if memory s...

differences between the b1 and b2 are a slightly different cam , the b1 has restrictor plates in the intake manifold , and the ecus are different . they are close but have different fuel curves due to different cams .

a common upgrade on the b1 is convert to mpfi and put a d16a6 or sohc zc cam in it

if its a d series it will bolt straight up . only differences you have to overcome will be wiring depending on what motor you end up with . but the mounts are all the same . might need to switch the coolant elbow , to prevent a kink in the upper hose

i would have hit it with a micrometer to see , but you already found your answer . hope it fixed your problem

z6 is one as previously stated a y8 head will also work but is obd2 versus the obd1 z6 . by swapping the whole motor you get to take advantage of the extra displacement a big .1 . i think you only gain 10-15 hp and tq by doing a mini me, so depends on the overall investment made for its worth .

the si-r was designed and manufactured with that motor

A true cold air system like the one made by a.e.m. draws air from infront of the passenger wheel well going threw oem hole . The idea is that you still have inner fender Wells (black plastic ), thus creating a box to contain the filter. Had one on my first Rex cut a small hole In the factory slot of...

Um ok we'll if done right with proper machine work of the head you should not need any .if you insist a high heat application at least do to operating temperature

I only apply extra gasket maker on oil pans and valve covers . Thats me personally tho

Thank you I will add that to my list for the junkyard trips
