Just wondering how weak D15b rods are? Are they as strong as the D16a6 or any of the other D series engines... Will ZC rods fit into a D15b.. Thanks for any help.

Drew Peacock

Sorry its a JDM D15b they are vtec, if it makes a difference

hey man. I boost 7-10 psi on my D15 B2. with the right tuning your ok... it is not that hard.. my car has never been on any machines or dynos.. and runs the jdm d15B is almost the same.. but it does have rods real close to the a6 setups.. but it made to rev high for vtec..

Drew Peacock

Great how long you been boosting? I imagine the zc rods wouldn't be any stronger don't you?

eg6turbo

i have a jdm d15b vtec in my eg and its hold quite well to 8-9 psi with just fmu and fuel pump...hit 172 hp with about 7-8 psi...how strong???? well i think it should be just as strong as a d16z6 or maybe a lil stronger....afc hack will replace my current setup and more dyno tuning is in the future...

I saw a stock d16z6 (dont quote me on the engine quite poss. coulda been the y8 or y6) anyways he was making some 275hp on stock internals. I think he had a standalone, again IM not positive, just made me think why I bought a B series when D series are making just as much power..... cheaper.

Thanks for the replys guys anyone else out there, any comments on the zc rods fitting into a D15B2??

Drew Peacock

Anyone

*Boostwerks*

The ZC rods wont do anything for you. They are pine needles as well...

Zero_son

Don't the Ls rods fit into the D15b2?

b16ahybrid

I believe he made 275 whp on a stock d16 but only for about 5 seconds. A d16 would never hol up to that kind of power no matter what kind of fuel management you have. The rods would bend before you made that kind of power.....175whp is another story

Drew Peacock

No actually he's right boostedED9 I think his name is has run that setup for a while, but that has **** all to do with a D15b2 so please keep on topic!!!

havok hybrid

well i just ran a 240 that ran a 13.3 with in the week. and i beat him.. with mt d15 sohc.. on 9 psi.. car will pull a 12.9 im sure of it.. and that was on 91 pump gas.. d15s are WAy stronger than d16 (a6) and such.. the newe d16s might be stronger

b16ahybrid

depends on which d15 your talking about....usdm (d15b7 etc) are weaker then the d16 but i cant speak for the jdm d15...

b16ahybrid

Not calling you a liar because i've never seen this with my own eyes, but i won't believe it until i see it......Please don't go and try to prove me wrong, i'm not disputing it..i've just never seen it... if it's actually been done.....thats a lot of power for a d15 to handle.....thats about the limit of a b16 (well closer to 300whp) and they are a lot stronger then a d15....
I guess my disbelief comes after seeing a side by side comparison of d15 rods and d16 rods.....

Drew Peacock

The guy is talking about a D16!!! Thats why its not on topic... But you are right that guy is pushing his internals to the very limit it is extremely risky but so far its working.. Check him out he has the dyno sheet in his sig and has done a 12.7 or something close

Thumbs up Havoc Hybrid good stuff!

whacking stick

Just thought i'd bring this post TTT

Does anyone else have information about JDM D15B rods/pistons?

I know 'eg6turbo' is running 9psi happily but ive been told by the place which is doing my setup that my rods or pistons wont last long under this environment but will be sweet at around 6psi.

if anyone knows anyone else with a JDM d15b turbo setup, please let me know.

Thanks.

eg6turbo

hahah i dont think too many ppl have this setup...this was the main reason y i went d15b vtec turbo....casue i wanted to be very unique...alot of ppl ahve doubted this being unsafe over the long run.....but i guarentee that it will last just like any other setup witht he right tuning....but i would really like to know also what other jdm d15b's are out there that have entered the darkside....

mos

Honda D-series rods holding 275hp?? Let me check my *** to see if monkeys are flying out of it.

eg6turbo

ahhah so how much u think they are good for????? i have 202 just 72 off lol...but he does have 4 psi more then what i ran on the dyno....

whacking stick

Yeah, Im yet to suss out where im going to get my tuning done but I have a fair idea. I'l probly be using a link plug & play computer, 2 extra injectors (probly around 500cc), T25 turbo, custom manifold and probly only run 6psi to begin with (on standard internals). What do you think?

The shop said they turbo'd a JDM d15b (as this engine is quite common over here in New Zealand) at 4psi on its first run it bent a rod. This could have been for a few reasons but it still gives me doubts about the internals.

well i had my d15z1 (vx motor) running 8psi with only check valves and 42psi fuel pressure,I even saw 16psi from the d15 when my wastegate hose split!Didnt blow the motor but the turbo blew the oil seals,i heard that d15's actually respond better to boost than d16 ,the head is ment to flow better??not sure though ,anyway my cars been n/a for the last 8 months and still pulling remarkable hard for a vx ,Ive got a new setup that i been building up.
Im hoping for the 13sec bracket ,what sort of power will i need to push me into that bracket.

note:its a freak off a d15z1 only mods air filter +2.5in exhaust (from turbo setup)
and ive betten d16 vtec's d16's 1.8 mirage's ,Keep up with cars with double the horsepower,Im keen to dyno it to see what power figures it puts down .It can run 400m with a trap speed of 135km ,if anyone can work a time out of that?

sorry went a bit off topic

I've seen mid 200s on stock D series rods for over a year.

im curious... what hi-performance internals do u have .....im thinking about going turbo on my d15b...i was spraying a 100 shot (dry shot)and by the second bottle..... my car is smoking....the farthest two spark plugs got burned up....i replaced them and the car started actingt normal again...then the other days i saw the car smoking...to make a long story short...i wanna get another d15b and get full internal work just for turbo setup.. now im wondering what u recommend for the d15b to go turbo...
