Thanks. Next step is to upgrade to MPFI.

This motor seems awesome on the autoX course as is. I don't think we need much more power, just some adjustment behind the wheel.

hey sorry to jump into this one but i just got a jdm d15b and well no one posted pics of there motor and i was wondering are ur spark plugs are in the front of the motor also mine was fuel injected. with out the block of plates. i used my y8 manifold on it and well im just trying to figure out what the hell it is.

this is a jdm d15b vtec motor, are you looking for vtec or non vtec?

Our SOHC non-vtec

If you look at the cam, you can also see there is a 17th cam lobe for the mechanical fuel pump right by the distributor.

what i want to know from those two pict below is,.... can i just swap complete head on this two engine?, is this two block is the same? its because i have this two engines lying around, 1st pict is carburetor and below is a sample picture not mine..

Hadouken!

It's most likely a D15B7, at least that's what I have in my 90 CRX. SOHC Non-Vtec. Pretty quick for no vTec and DOHC.

sry to bump this thread but im having a hell of a time geting info on this subject 2. first of all if its a jdm d15b non vtec if u have mpfi u should be fine with that head get a pnp 3 angle valve job and a good cam. Like delta. For the block ul need to raise compression so p29 pistons and y8 hg and u may need to mill the head a little. Now the prob ur gana have is that the rods are week and some people say there 134 mm others say there 137 mm if there 137 u can get after market rods if there 134 mm get them shot peened. No the prob im facing is i dont live in the usa and i cant get them shot peened so if any one has a spare non vtec block and can messure them that would be great cuz i dont wana tare apart my engine and find out there 134 mm. Its my dd
