yes it will...you have to use the cams out of a GSR or b16 to egual out the super valve lift decrese of the DOHC zc cams. After the head is on the block, run a bead of JB weld around the head/block mating surface to insure a good, 100% headgasket seal
search it!!!!! :cussing:
It's possible, but unless you have access to a mill, it is going to be very diffucult. There is only ONE confirmed case of this I know of, and it's running, but we have no longevity to say if it is worth the time and effort.

B-series camshafts will not work in a D-series engine - they are about 2" longer than the head and cylinder spacing center to center is greater on the B-series due to the larger bore size

which bolts up fine, then you have to deal with mount problem using the teg block.

along with the transmission not bolting up correctly and only one bolt in the starter
Yeah provided the D15 has the same head bolt pattern as the D16 then it can be done.
It wasn't expensive at all. If I'd paid somone to do the machining it would have been about 6 hours work.
It took longer lightning my flywheel and crank pully than I did re-boring the head holes.
Remember half the stuff I did to my motor was unnessessary like the 12mm head bolts and re-tapping of the block. I could have just stuck with 10mm bolts (OEM wont work too short) and saved myself a lot of time.
Without the headbolt conversion I'd say you'd be looking at about 2 hours tops on a mill. Shit you only have to move 3 holes between 2 - 3 mm.
The biggest expense was the hardcore bolts i bought the 180mm long one was $18 the rest were around $15
The only slightly dodgy thing about the conversion is now I am not running locating dowels.
If you want advice though, find out everything you can about your engine before starting the job. I know for one you will have to use PM7 or P29 pistons to make use of the DOHC head and it's 43cc combustion chamber.
But also you need to compare the oil galleries between the head and block and make sure they are compatible, it works on the D16 but it might be different with the D15.
Have it all planned out and know exactly what you need to do.
