Default ///////////// do 300zx pistons fit in a h22???? i was told they do!!!!!!!!!!!!

i heared from a turbo guy i know here that people have been putting 300zx pistons in there ludes, he also owns a lude, and he builds turbo kits for a living, i dont question his credibility. but i do want to know, would it be safe... and would everything line up????

there both 87mm and the 300zx ones ar 9:1 comp

but would it stay the same compression once they are in a lude???

i am curently in the prossess of sleeving with darton sleeves, and i wanted to know if these would fit, and if there are any known weaknesses with these pistons!!

are they strong enough to hold 15psi

would my car run ok?????

im sure there would be many ppl interested in this just like me...

and maybe someone has some anwsers

thx

Im guessing that they wont work since H22's have frm cylander walls. I suppose they may work if you either sleeve your block, or the 300zx also has frm cylander walls...which I dont think it does.

the 300zx does NOT have frm liners. the pistons may very well work, but you wont know till you put one right next to ah series piston and compare. ive seen it dont in domestics for years.

...where do you people get these ideas? And don't put those annoying //// things before your thread title, it looks stupid. Kind of like using too many question marks or exclamation marks.

What would be the point of putting 300zx pistons in an H22....what is the rated compression that these pistons have?

I dont really think it is fair to compare these rediculous ideas to that of using 300zx pistons... Where is the humor in that? People use suzuki pistons in d-series all the time... 99% of custum ITB's are taken from bikes... people use ecplise and rx7 injectors all day long for boost setups... Domestic guys like to use gsr rod bearings... I don't see anything wrong with that...

I think the point would be to have pistons strong enough to hold boost without spending $4-500 on aftermarket ones... The TT models see a decent little amount of boost...

things that would need to be known would be compression height, pin bore, dome cc, valve releif cut out diameter and depth, as well as the width and beefyness of the 300zx rod

fidn all that out , then we will let you know. even if they did work you prob need to sleeve because the frm will eat the pistons

Dont even bother with this, HUGE waste of time... Aftermarket forged H22 pistons are less than 500, I cant see why anyone would even consider using 300Z pistons...

Compression height, wrist pin diameter, bore, valve relief depth, valve relief angle, valve relief spacing are all factors that need to be dead on for it to work...

You also mentioned that the Z pistons were 9:1 in the Z block.... correct? What stroke, deck clearance, combustion chamber volume combination does the Z have to yield such results? I can guarantee you its nowhere close to the H22...

To some it up, No... x 2

Under $500!

the difference in rod length is 11 mm, but the deck height is a diff or almost 32 mm, that makes for 21mm of mismatch, so they will be 21mm too tall....

sorry

Hmm, this is a very interesting idea.

But it's too bad math owns everything.

That's a big difference.

At least with D-Series guys, many have used the Supra Turbo Pistons and B16A rod successfuly on their stock D-Series crankshafts. The reason for this is that some guy used to sell it for around $600 for the pistons/rod combo, which is cheaper than a Forged Piston/Rod Combo and was able to handle 12 - 14 psi safely.

bore is .5 to big, compression height can be delt with, pin diameter is to small, and still need to know the small end of the rods width

The problem with that set up is the fact that the guy selling the stuff had no idea what he was doing. The compression height on the 1JZ pistoons is much taller than the D16 so compression was actually a lot higher than what he had thought. I dont think he even understood what compression height was, I remember sending him an e-mail to pick his brain a little. I remember thinking to myself that I wouldnt let him within a planet of anything Im buuilding.

The other thing was the use of B16 rods. The 90mm stroke of the D series motors and the short B16 rods were not a good combination for a boosted motor at all. You are shortening the rod length by .104 from the stock 5.394 which drops your r/s ratio down to 1.49 from an already low 1.52 in stock form.

That whole ordeal was retarded from the get go, as is the idea of Z pistons in a H block... We as honda owners have an excelent wave of aftermarket support. Theres no ned to do any ghetto half *** stuff like this. Forged pistons are made for our motor and come in serveral options and variaties. This kind of thing is best left for your hot rod suzuki or kia owners that dont have any options.

look, i wanted a good anwser and i got one, but the insults are not needed, lol, its all good, but anyways, i still wanted to know, and im not exactly the best person for motor building, nor do i work as a mecanic. i just wanted a "dumb question" anwsered,

but thx guys for clearing all that up!

btw: the z pistons are not 87.5, they are 87mm, the only reason they are marked like that is cuz they are oversized, those are not original specs, those are for forged pistons like the person mentioned! i think he said from WISECO,
