xt/xtp pistons

[zil40]

i am looking for pistons for my ca and found on raceeng.that they had the xt/xtp pistons i have never heard of them and was wondering if any of you have ran them i cant seem to locate any others but im also on a budget also if i were to go with stock replacements where would i get them thanx for your help i have looked at racetep/raceeng/speedware/ and others wil little luck

XT and XTP are their names for their custom designed pistons from Wiseco and CP Pistons (in that order respectively, I think?).

I have the CP Pistons from them, 1mm overbore. Several others have these pistons in stock or otherwise custom configurations.

If you want something that's not listed on their site, call. I custom ordered my 1mm over pistons.

i saw them for about 450 to 469 on there site i also saw that they have 83.0 and 83.5 i have a stock motor othere than the head and everything being fresh just wondering what you guys suggest i plan on running a sr t25 550cc inj front mount what do you guys think thanx the goal is about 300hp

Im using 83.0mm CP Pistons in my motor. I cant tell you much else as my engine is not yet running. You wont need these pistons for that power goal but it's always a good thing to change to the forgies. If your tune is correct meaning you've got the right amount of fuel, air, and spark timing you could make it this high with the stockers. You could also do it with the forgies. My recommendation would be to change the OEM units if you can.

Back a few months when i had ordered the CPs, i took my block to my machinist and he was impressed that i had chosen the CPs. He knew they were good and are worth the money you spend on them. I was just happy that my motor was getting some better pistons!

I'm running the CP pistons from them as well and am very happy with them.

I plan on running CP's

but that really bears no relavence on this.

[zil40]

i had looked at getting stock pistons but dont know where to get them but iff i can get forged for cheap that would be great but where would i find stocks anyways

[240 Trainee]

I have an extra set of stock pistons, and I'm sure others have some that they would sell on here was well.

[zil40]

how much do you want for them what kinda shape they in are they userd or new i kinda want new if im going to rebuild it but im in need for some for sure

[zil40]

do any of you guys think putting used pistons back in is that great of an idea im new to all this so any help is better than none

[240 Trainee]

I guess they are in fine condition, they are in my stack of parts.

Your not going to get new oem det pistons.

[zil40]

what would be the draw backs of running a set of used pistons from somebody els i was waiting for tax money and i dont know when that is coming in at this point so if i have to put stock back in for know i will so how much would you charge for the extras you have

[tineira]

Your not going to get new oem det pistons.

Why not? Y just bought from my local nissan dealer for about 140USD in 83.5mm. I live in Chile so it may be different there, but you could special order them, they are still in production.

[240 Trainee]

Well, at least at a US dealer, DET pistons are different that other US avalible CA pistons.

[zil40]

well it would be nice just to pick some stock new ones up for now if they were not to spendie think it would be to costley to have some shipped in or do you guys think it could also be be dangerous that i may not get the right thing just a thought

[zil40]

ok sorry for all the post on this forum but i pulled the pistons and it had brocken rings so i was wounderi8ng if i order some rings from cp or raceeng.com do i get the 83.0 or the 83.5s for the stock pistons i will hone it out a little to clean it up but i need to know witch will work if you guys can tell me as soon as posible that would be great i just want to order themthanx for all your help

[mod_mastaz]

You're going to have to measure the current bore and see how much wear the cylinder walls have. The fsm will have info on how much is acceptable. If it's within spec, then all you need is stock sized rings and a hone.

[zil40]

will stock rings from a ca18de work or do need det rings

[zil40]

or will ca18et piston rings work im kinda lost so im trying to figure it wout
