Vitara Pistons?

[©urbow]

I am just wondering how good these are? i have done some reading on them and have noticed that they are used quite a bit.

thoughts?

Also what might be better? i'm gonna be goin for 250-300whp

PM fjt, he sells them for $128 shipped

and they have been proven to 400+

[Eyal 951]

if you are only after 250-300 whp, you should consider more then 8.5:1 CR. A good tune, and you can easily pull off more. These D-series handle a lot before detonating.

For something as vital as pistons I would not try to skimp. You would probably be much better off buying from a reputable manufacturer.

do a quick search on vitaras.... they arent skimping...
also fjt said his price is going up sometime shortly... only like 15 bucks though

[drunkinmaster1]

i use them and my car make an upwards of 400 hp with no problems. the vitaras imo are the way to go.

Gotta love the boost on a budget

For something as vital as pistons I would not try to skimp. You would probably be much better off buying from a reputable manufacturer.like i said they have been proven to 400+ and hold that power level quite nice. i cant even count how many 300+ setups ive seen...

[©urbow]

Sounds like they are good pistons from what i read, now what about TT rods with them? i have also read some on that and have seen some good things.

[©urbow]

ALSO...... would 20psi be safe with this setup? I have been told that i would not be able to make 300 at 15psi like i had planned.

psi means nothing alone. We need motor specs, turbo size, and a million other factors...

[©urbow]

Well, i am not sure what turbo yet. i asked in this thread....http://www.d-series.org/forums/showthread.php?p=661554#post661554

In there i was told a t3/t4. or 16g. i'm not sure though. i'm a noob when it comes to turbo sizing.

[drunkinmaster1]

i use a t3/t4 57 trim .60/63 stage 3 wheel. that puts out a decient amout of cfm and power. i run 18 psi everyday around 350 hp.the car has been ran on 25 psi on pump gas.
JFK78 on hondatech made 416 hp @ 30 psi with the same size turbo.

heres my dyno.

does any of this answer your questions on the vitara reliability.

[©urbow]

yes, it does.... Thanks a LOT!....+1

what do those run in the 1/4?

[lowcrx]

i've wonder about those pistons myself and all i hear and read is good things...not one bad thing about those pistons.... the only thing i don't understand is do you have to horn and bore the block with those piston or can you just through them on some eagle rods and install....very confused

[drunkinmaster1]

what do those run in the 1/4?
fast2camciv ran my car 11.43 @ 127 when it was his. he got booted from the track for not having a roll cage.
JFK78 ran a 11.706 @ 126.28 mph on 23psi.

[lowcrx]

congrat on the time!!!

When did you buy the car? I'm confused now...

[drunkinmaster1]

i wish i could take credit. but all credit goes to Brandon Deitz

:werd: i thought that hp sounded familar

the first over bore on these is .040 so you would have to bore out to 76mm.

thanx i was kinda confused about it!!!!

[drunkinmaster1]

i bought the car a couple of weeks ago. but enough about my car. this is someone else's thread about vitara pistons. i just wanted to throw my 2 cents in about how successful the vitaras are.

[©urbow]

I'm glad i found this information out. Now what pistons do i buy? the y7 or z6 pistons? (i'm going with a y7 block and z6 head) I want the lowest compression possible.

So the pistons are not stock size? i am gonna have to bore it?

[civic97]

yes they are stock size. i was just saying if you do overbore its .040 not the typical .020. these where made for motorcycles so no y8 or z6 ;) just get a set

[drunkinmaster1]

the vitara piston is a 75 mm piston. it should fit right into your d-series like it was meant to. a light hone is reccomended to set the rings properly. i prefer a ball hone for a little heavier crosshatch

[©urbow]

yea, i'm gonna have to get hit honed anyway because of some surface rust from condensation. So what will my compression be (about)?

[drunkinmaster1]

compression varies based on the head, piston, deck height, gasket etc.
the vitaras are a lower compression piston than standard d-series pistons.
heres a compression calculator to help you get a resonable idea.
i hope it helps.

you can get the Nippon racing ones, which are Vitaras made by another company, in .020 oversized

[EG_GSR_HB]

Arent these the only pistons for a jdm d15b?

DEITZ is a badass!!! he is going to help me build my HF here in a little while. That car is hella sick, congrats on the buy

thats awesome.
is it going to be a vitara settup? i really hope so, id love to see what his next build is gonna be. gotta rep the vitara piston.

well i attempted it but i dont know all of the information. i am going with a y7 block and z6 head.

[©urbow]

Just a few more questions from me on this......

Are these pistons motor cycle pistons? for what motorcycle?

Can anybody help me out on that my compression will be?

[jimmyb34]

they are from a suzuki vitara... an suv
and your comp will be around 8.5

[kulo]

will these fit b7's?
