I am trying to figure out what head i just received. I looked on the head code list and did not see it. http://i5.photobucket.com/albums/y171/WakeboarderX30/P1010042.jpg

Also from the pictures that i have seen Z32 turbo pistons had a dish and were not flat top. What piston's are these than?

I don't know exactly, but since the euro sr20de pistons are flat top, these gotta b either sr20det pistons or sr20de pistons, depends on how big the dish is

The dish is really small. So these are not Z32 pistons than?

I guess u are trying to see if u have z32 TT low comp pistons. The z32 NA ones wold have a dome. I don't know. What makes you ask? Why dont u think it is not a stock piston? That is a standard head, no?

Cause it's supossed to be GTiR Rods w/ Z32 Turbo pistons and the bluebird head.

measure the bore, that should tell you right there...

suppose to be..... aww man.

That looks like a SR20DE piston.

Here is a thread that shows 300ZX pistons

If it's 86mm, its stock DE, it it's 87mm, it's been overbored.

nope, thats normal Sr20 pistons,, most of import motors have those,,

Well what should i use to measure?

*sigh* I hate it for you dude, but you got served.

Yep, served a big steaming plate of bullshit. I bet your rods are stock too, fwiw. You can measure with a tape measure, actually - the widest you can manage to measure should be 86mm for stock, and 87mm for Z32 pistons.

well i measured and i knew it would be off a little but i came up with like 85.738 or something. so guess it's 86mm. :mad:

ok im the one who sold james the motor...i bought it off of silverballspecv about 2 years ago and never took the head off ( my fault...i was going to put it in my sentra but bought a VW instead ) when i bought the motor this is what i was told from the person who built it ( travis buell sp? aka unlucky aka from FIR )

Hey..

It's a DE block.. with a DET head. It's got 300zxTT pistons.. which make it 9.1:1 C/R. It's got S3 camshafts, new springs, new rod and main bearings, new rings, new seals, new timing chain. It's been hot tanked and I had it blueprinted when it was assembled.
Travis

now i need to know 100% that this is not what i was sold...i will in turn contact travis and try to figure this out...im not trying to rip anyone off here and i def want to get the situation rectified! james i messaged you back on myspace so lets get things figured out!

Aaron

also did it have the cams that it was supposed to?

I'm not trying to blame you man. I know that you got it from someone and didn't take it apart. No hard feelings or anything there. Just kind of was confussed when i took off the head and the pistons looked the same as the old DE block i took apart. Also i cannot verify the head. It's not on any of the head lists on the forum. Not trying to give you a bad name or anything man just wanted to find out. I know your a good guy and didn't try to screw me over.

Looking through my Avenir W11 install pictures, I found this... not sure if yours states 53J in the same spot or not.

Mine is behind the thermostat housing. More under the distributer. And it says 53J 6R

My 91 se-r stock motor has 53J and 82 in the same place as yours...

you can verify the head by the exhaust valves. sodium valves have a 7mm stem and are marked on the valve face.

..i should have just let you take the head off when you came and got it from me before all this went down...hit me up and we can work out some financial stuff...im more than willing to give you some of the money back....also im going to get ahold of travis and get this rectified
