hello people, i just blew my motor, it was a b7/y8 mini me, with a small 16g with 7.5psi boost. it had 152,000miles on it, with jsut a base map. it lasted all year and i was pretty happy with it, until i took it to the track and blew it up on my 5th run.

Anywho, I just ordered a d15b longblock form hmotorsonline.com and im looking for a camshaft that will spice up vtec a bit. when i put the y8 vtec head on, i wasnt very impressed, i really couldnt tell any difference, mabie 10whp at the most.
i hear most peaople like the zex cam for sohc, any info on wich camshaft i should get given my setup would be appretiated.

I want to keep this set up cheap simple, so the motor will stay stock. other than a 255walbro fuel pump. and a camshaft.
This time i will dyno tune it, also will be using Neptune EMS.

Also alot of ppl are making 230whp on a stock sohc. how is this possible? my friend has a d16y8 with a 14b and blew his hg on 10psi, then got arp head studs and warped the head on 12psi. wich could only be making mabe 210whp max.

 

oh ya also need a site for cheapest arp head studs. thanks

 

?

 

Delta regrind ...

 

59300 zex cam will do the trick. it says u must replace valves and retainers, however a lot of guys do not and run it fine. Just dont rev the motor past 7.

and i know their is one lingering around in the F.S. section for 200 shipped

 

whichever cam you pick it needs to be for d16z6

 

59300 zex puts out impressive gains on a boosted D, and its been used countlessly and reliably for some time.

 

great thanks guys zex cam it is. And im lovin the price!

 

i thought the jdm d15b vtec already had a good cam in it. i still liking mines

do you know what the specs are on it?
also can someone tell me what the specs are on the zex cam. and do you think it will make good hp with the small 16g?
will it make peak power from 5,000 to 7000rpms? or is it more of a top end cam?

 

5000-7000rpm is top end of the D15b. look the specs up for the zex cam, the D15b cam is only claimed to be better than the z6, so compare them to the z6

Delta only does non-vtec camshafts

ZEX would be my rec

 

the jdm d15b already has a decent cam in it, alot more agressive than a z6 cam. its actually the same as a zex stage 1 I was reading on turbod16 and hmt. Ive seen guys make almost 300 on a stock D series turbo. Its all about tuning and good fuel management. Also you should of noticed a big increase with the minime if you did it correct. did you wire up vtec and get a vtec ecu?

show a thread where it was proven, not talked about. nobody to my knowledge on HMT or turboD has proven it. mista bones was going to check it out, and as far as i know he didnt come to a cunclusion whether they where differant or not. if they are its unoticeable. 300whp on a turboD is nothing.

Yes vtec was hooked up properly, with chipped p28&neptune ems.
and i did feel a difference, but i jsut thought vtec felt pretty week, and i had a Y8 vtec head. do you guys think a z6 is more aggresive than a Y8?

not everyone can sucessfully build and tune a motor you know. there are people making way more than that on completely stock motors, HG, head bolts, rod bolts, and all.

 

uhh 300whp will put u in 11's definately and last time i checked thats pretty good for a all stock turbo D.

 

all i know is the d15 is different from the z6, the pistons are basically the same but there is something about it that makes it a littl bit faster. When I first got my jdm d15b in my 93 dx coupe and i was racing a 95 si hatch with i/h/e and walked the expletive out of him by like 3 cars. I dont know though its still no proof but I think its alot better than the z6 and y8.

 

Instead of spending what, like $250 for a cam, save $500 and buy an LS

the pistons are nothing alike, the arent even interchangeable *without modifications*. they produce identical performance numbers, due to the slight increase in compression and hotter ecu maps. the head and intake manifold are identical, other than that nothing about them is the same. if you walked an SI hatch w/ a d15b coupe its cuz of the launch, driver, or beat to hell z6 in the hatch. my buddies z1 (92hp) hatch will beat an ex coupe w/ a descent driver.

 

what tranny are u using..the best gear ratio for the d15b would probably be ex/si tranny. if anything maybe even a dx tranny. i've got a stock cx tranny on mine and its embaressing how i get beat by a z6 hatch by like a car. the gears are just too long. i've got a p28 ecu with vtec engaging at 52k. when vtec kicks in..it sounds like im goin somewhere..but im really not. lol

pm me

 

sohc for life. As for the pistons they are basically the same ive pulled both motors apart, even though one is a p28 and the other is p08 they are both dished pistons. Im not saying they are identical but they look very similar. Your making it seem like an LS piston and a CTR piston.
