SOHC Inspiration right here...triggered and ready to do a build. Was considering B series build but you’ve proved otherwise 👍🏽 The fact hat you’ve built this yourself is a whole different beast
I've had the same issue on my b18c1. these ignition systems dont hold up in high boost high rpm settings for long. I went coil over plug setup with an EPM from AEM and Twin fire module. Never had an issue or looked back since.
How laggy is the setup? I ll have my d15b 3stage vtec vitara pistons build mapped next week. The turbo I use is gtx28r. I am hoping to see 400bhp on the flywheel.
Patryk Kozanecki with a standard length D16 Rod the Vitara pistons in the d15b and that Turbo you should be spooled up pretty quickly. I don't see full Boost until 6100 but my Turbo is much bigger than yours
Well u obviously know what you are doing. But you have all high dollar brand name parts for internals then cast pistons on high boost... U obviously could afford forged but like to play with fire risking that bad ass engine u built... In my oppinion. What are the specs on the pistons that you put so much faith in. Sry I'm not trying to be smart and have much respect for u.... Im genuinely curious
hey so big question. i was considering taking my d16z6 head to get ported and polished at a machine shop. which i have never done . if i take it to get ported and polish wont i lose compression? i know you gain that compression back while you turn up the turbo but im a little confused. how was you able to do yours?
Jayspassion you wont lose compression unless you modify the combustion camber. Also i have the required porting bits to do the job but you can make more than 400whp whit the stock ports
Sorry to bother ..but what cam gear are you using and where is it align to ..having trouble findind the right spot on the aem cam gear on the d15b for tdc
@@hatchbackturbo93 strange I dont have a solo mark ..just one set of 2 lines and one set of 3 lines ..and i assume the 3 lines are the ignition marks ..but I set the crank pulley to the 2 marks ..but don't know if I should set the aem cam gear lower mark directly on the arrow or passed it on the upper timing cover ..do you have a email so i can show you better ?
ey bro quick question im about to install my head on a d15b but but arp bolts stick 1/8 above the head do i raise the bolts up? what is the part number for the arp bolt you use thanks

jevvy boss yes but only with the jdm d15b. It uses standard D15 main bearings and standard D16 rod bearings. The d15b uses a different piston than any other d-series motor and the difference is the PIN height of the piston. The stock D15B rod is actually the same as a d16z6 rod. the Vitara Pistons also have a different pin height then any other dseries piston. when used they normally sit 2.6mm below deck height so the extra length of the 1.6 rod (3mm) with the Vitara piston makes the piston almost the correct height it actually sticks out of the block .5 mm
jevvy boss this is why vitara piston setups have such low compression 7.2.1 ect... This setup im running should net a 8.8.1 compression ratio, that's with me using .50 mm head gasket rather than a .30 standard gasket
jose perez i purchased my rods and pistons from speedfactory but there all over ebay. And yes it is basically the same motor as the d16z6 and d16y8 depending on whether you have an OBD1 or an OBD2 motor
Team Poko the motor is a OBD1 d15b so the head is basically a D16Z6 head without an EGR port. I use a cometic c4251 .51 with this setup. Any Z6 head gasket would work fine
hatchbackturbo93 thanks buddy because im also building a d15b for boost and a friend of mine told me the deck is shorter on the d15b so i would need a thicker head gasket he said ive been having a hard time getting answers also i know for our engines the rod bearings are for d16 so washer and block bearing should be d15z1? thank you buddy
Team Poko yes D15 Z1 Main and thrust washers and D16 rod bearings. The gasket i use is .5mm thicker than stock which is what a vitara piston with a std lenth d16 rod (137mm) protrudes over deck height.
Team Poko the block is the same as any D15 block the difference is the crank stroke on the d15b is the same as a D16 the d15b uses a completely different piston than any other motor
