my friend said he was running a mugen "chipped" p28 in his gsr. is this possible?

Ravage70

jdm d15b has longer rods than usdm d15b but shorter than d16s.

Oh ya and have fun trying to find aftermarket rods for that.

I tried and i found out that building a new d16 block with my d15bvtec head was the best idea.

So if ur gonna boost with more than 11psi like me stick with the d16s and the widely available internals.
Thank you, Have a nice day

BTW d15bVTEC has a P08 head

VtecvsVr6

Well thing is i already did the mini me with a d15 bottum end and a y8 head this winter another thing is i was hearind i need to run a oil tap or osmething like that?? And waht ECU should i use to engage my Vtec or just buy a VAFC?

The d15bvtec uses the same pistons as the z6? Are you 100%? I'm gonna be building up a d15b and picking up the head for 150 and the block for 50 cause it needs a piston and wasn't sure what they were? He had a z6 block left over and said I could have that for free so if thats true I just swap over slugs.

d16z6 and JDM D15B heads are identical. P08 casting.

stillnoturbo

Same casting for the two heads but the d15 head has a more aggressive cam and the p08 ecu is used with jdm head to better use the cam than to use the p28 with it and the p08 uses a single wire O2 sensor I believe over the 4 wire p28 ecu.

my jdm d15vtec came with a five wire 02 and the p08 ecu. I just put a 4 wire in and use a p28 that my friend burns chips for me. So if anyone has any ecu needs, putting in a socket or burning let me know.
