One question: does the vendor have the pistons in stock? Specifically P4-MA790-N10.

i am talking with the vendor/supertech to see what is available right now and how long before something will be available.

please pm or post up ur part numbers so it is a little easier for me to keep this organized.

these are the only part numbers i have been given from everyone.

P4-m84-p2 6 sets on hand
P4-ma790-n10 – none – 1-2 weeks out
P4-ma84-n4 very similar to cr9 (no more n4 superceding to cr9) – 0 sets - aprrox 2 weeks
P4-m8350-p2 – 4 sets


also, i got the ok to on the wiseco, so if ur intrested in the wisecos, give me the part number

What exactly does this mean, i would be interested in the p4-ma84-n4, but not he cr9.

supercede
Definition:
To replace in power, authority, validity, or importance.


the p4-ma84-n4 (8.6:1) will be replaced by the p4-ma84-cr9 (9:1)

Wow, i am so glad you can quote a dictionary, the question was why there are no more of the preferred compression/bore for most turbo applications, is this because they stopped making them or what, because while 9.0 is "very similar" it is not the same.

i'd rather have the 9:1 vs the 8.6:1

supertech has discontinued this part, it is being replaced by the cr9.

...I should probably learn about this shiat so I can make an educated purchase rather than just join in and buy since they're cheap.

Thanks for doing the legwork for the deal, whether or not I get to join in. :)

Well that sucketh...

Guess I'm in for set of P4-MA84-CR9.

Do we know what rings they're including?

they are including the rings that go with the pistons (the recomended part#)

I PMed you what I want SOB. Where are my pistons!?!?!?

I'd like the K553M84 Wiseco's. Also, what's this "different valve angles on 1999+"? Interested as these are going into a '99.

i called wiseco on this
"the 94-97 head has different valve angles than the 99+, so pistons for the 99+ head would need to be custom ordered for about 140$ a piece/560$ a set"


i will call supertech to make sure this is not the same for there pistons

I have a set of the 83.5mm 8.6:1 pistons with rings that I'd be willing to trade someone if they order me what I want in exchange. I'd probably go for the 9:1 84mm...

ok, supertech said that the pistons will work

P4-ma7850-n13 – 4 sets in stock

this will end on the 30th,

PLEASE MAKE SURE U GIVE THE CORRECT PART NUMBER

Is this different-parts-for-99+-heads deal also true for low compression pistons?

this is for off the shelf parts. not custom parts
