vitara p2w clearance.
back in the game.got a z6 for a couple hundred. looking for high 300 low 400's. vitara setup of course. measuring everything out and matching to specs. (piece of mind) Just wondering if any specs are not matched to oem factory specs for higher hp builds. Ill have pics of my block soon. will probobly turn into a build thread, just too busy with work/school for pics. will be honing at school this work and measuring.
what do you recomend for p2w clearance for high hp d's? D16z6 (FAQ talks about only 75.5 vitaras) also, can someone with a vitara 75mm give me an exact measurment of the piston diameter? also looking for some input on headwork/intake/tb for high hp 20+psi setups. |
Re: vitara p2w clearance.
Just drop them in go. ~0.0040" - 0.0045" would be a nice place, but most of the time when you drop them in they are sloppy like an old -----, but seem to be fine like that. There was a thread on this not that long ago and 90dx had just put his in, it was probably 0.065"+

Re: vitara p2w clearance.
yes and his build was never finished. so just because he has excessive clearance does not mean he wont have excessive wear/blowby. would like actual information not just opinions. everyone has those.

In a boosted honda 98% of the time you shoot for a 0.0040" to 0.0045" ptw, tighter if you are 150hp fanboi, and looser if you are building a 1000hp race motor. This being HMT, we just drop the vitara's in and go, ---- vitara's and rods and a whole D series block, costs less then just good machine work, or a decent head job, if it fucks up you just throw it in the trash and do it again. If you are too poor to be comfortable with that, then you should probably have something built with good parts, and get a good tune, so you don't waste the few $$$ you have. If this question is because you just bought over sized vitara's and you, want to double check before you take your block for machining. Then have them go for 0.040" if you are shooting for the 300whp range, and 0.045" if you are going to go to the track with some race gas and go for 400whp or beyond to the vitara record. |
Re: vitara p2w clearance.
since i took the time to tear it all down and clean it, i mise well make sure its put together well enough to make some good power. ive seen 200hp vitara setups and ive seen 400hp vitara setups. i would like to do as much as possible to get the higher end of the spectrum. in no hurry. the link was good info. would like more expierience/knowledge on vitara build to get me as close as possible to 400hp.i know hmt ignorance is bliss, but it only makes cars faster to a certain point O0

Re: vitara p2w clearance.
400 whp d series are hardly that easy to slap together let alone keep them from breaking on a monthly basis.
|
Re: vitara p2w clearance.
your 400hp d project really does not portray a complex build either. imo

Yes I always ------- miss a 0, my machine shop doesn't even call anymore, they just know. :1

Re: vitara p2w clearance.
Most of the pcv breather info i have seen ran a line to the turbo intake for vacuum. Is this needed? or can i just run two lines from vc to catchcan, than one line from catchcan to beather box port on block? and also does 90dx want to chime in and give some info on the fitting in place of the breather box? did you just tap the hole? what size? doesnt appear to be a lot of metal to play with there?

Re: vitara p2w clearance.
Well since I did 90% of the welding on 90dx's car, and was around when he built that and the ls, and ... I will answer it anyway
there are plugs on the back of the motor, you unthread, like about a 17mm hex. then you replace with ones with fittings, I think one he got right from honda, the other one took to long so we just drilled it, and I tig'd on a steel AN fitting. I have also done it ghetto style with just making another hole in the back side of the pan, jb welding a brass fitting in and good enough. No never bothered with the vacuum from the turbo or the exhaust. As long as there isn't any restriction you are fine, as PCV stands for positive crankcase ventilation, in other words it is pressurized, the more power you make, and the more boost you run the more this pressure, to the point that it can cause damage to seals, and bearings if it doesn't have a path to go. |
Re: vitara p2w clearance.
was talking specifically about the fitting on the back on the d15b. where the oem breather box is located.
and when you where talking about oil pan, you ment for turbo return? |
Re: vitara p2w clearance.
No the return is on the front of the pan, I have done ghetto return on the back for pcv as well. :1
|
Re: vitara p2w clearance.
Also 90dx's on the d15b is not tapped it is a B&R fittings piece that fits right in with o rings is held in place by a retaining bolt, and converts to -12an
Sorry I miss read what you were asking earlier. |

Get a dingleberry hone... drop'em in with the arrows facing the flywheel...

Re: vitara p2w clearance.
Just send it to a machinest to have it done. It'd be your best bet and having the bottom end done isn't that expensive. Be worth your money.

Re: vitara p2w clearance.
I want to say I had nearly .008, with the standard 75mm vitara's and a quick hone job. they rattle like ----------ers when the engine is cold and it burns some oil until it warms up then she's fine. i've got like 8,000 miles on it and it still runs strong.

Re: vitara p2w clearance.
any numbers on said setup?
