yep


fast2camciv- what kinda timing are you running at 23psi? on the high cam at the high rpms and in the last column (22.9) i think mine is at 16* or so. I saw some people running some crazy numbers with the vitaras.

Re: Vitara Sidekick pistons
 

how low does it make compression on a D motor though?

Re: Vitara Sidekick pistons
 

there's a compression calculator link around here somewhere.

I almost used vitara's in my current z6 build.
But something in me wanted to buy Wiseco..hehe

Re: Vitara Sidekick pistons
 

with a z6 its down to 8.13:1

Re: Vitara Sidekick pistons
 

this is the compression calculator that i allways use...
http://www.knology.net/~jediklc/dcalc.htm

according to that....my y8 block, z6 head, y8 2 layer head gasket, vitara pistons, yields a compression ratio of 9.18:1

well hears the thing....at teh moment im just using a step retard of .9 (VERY conservative i know) i just built a set of "det cans" so i can more acuratly tune my timing...i do all my own tuning and timing is still sort of a mystery to me, so thats why the conservative step retard....at the moment the map that i ran 11.9 on, at 23psi, at 7500rpm im at a total timing of 6 degrees...lol. this thing has a ton more power in it with some more timing....

Re: Vitara Sidekick pistons
 

$138 shipped? Just think, for only $300 more you could have had some good pistons. ;) If the stock d-series pistons were low compression like the vitaras I'm sure they would handle that kinda power too (300whp has been done on stock Z6 motors before by the way). ---- 250whp seems to be the norm on stock d-series motors these days, my car is ----- compared to what some people are pushing d-series motors to.

Re: Vitara Sidekick pistons
 

this is HMT. and i say if people wanna run a cheap setup let them. ringlands are thicker than a stock piston. they are stronger than stock. and people are doing 350hp plus on these. and i only paid 125$ shipped. beerbong when ever theres a vitara post on any site. your there to knock them. why the hate? not trying to be a dick. just wondering maybe you had a bad expierence.

Re: Vitara Sidekick pistons
 

i hear ya pat, but at the same time if i were going to spend a good amount of money on a motor i wouldnt ---- around with a d-series....i would have gone b...for the same price of a set forged pistons i got pistons (vitaras) and a set of barely used eagle rods (from HMT) and all the bearings...i have maybe 500 bucks in this block (the rest of the motor is stock) that im confident will be able to handle 400+whp. i drive this car daily on 23psi. ive run 11 second passes, and probably spent less than 2500 on everything. this is a budget setup that outperforms just about everything out there, but builtl with alot less money...thats why i run them :6

Re: Vitara Sidekick pistons
 

bbka-check this ---- out....https://www.homemadeturbo.com/forum/...?topic=68155.0

im sure 405whp can make a believer out of you yet lol!! completely stock motor minus a used set of eagle rods, and vitaras.

these things can hang with the big dogs and this is proof.

Hey fast, is your block posted? blockguard or anything like that?
