well i have a 99 z28 m6. the piston rings are bad and i dont plan on fixing it stock! i want to get the tsp 347 rotating assemblies kit. my plans for the car is too spray (150 shot) and i think im going to get ms3 cam. i was wondering what pistons and piston rings would be good for nitrous from this kit?

diamond pistons and total seal rings or call them up and see if they have some hellfire rings. for a 150 you should be fine with the total seal.

steel top is what you are looking for as in the top ring.

 

what kind of connecting rod?

 

I run diamond pistons with a 2.0cc valve reliefs and speed pro hellfire nitrous rings and bangin 2 stage 300 shot.

 

I have scat h-beams with the arp2000 rod bolts(7/16 bolts as apossed to the regular 3/8 bolts)

 

but is your motor a 347ci? would it be safe to spray a 200-250 shot?

 

mines a 347 yes, there are guys out there sprayin a single 300 shot on stock bottom ends with the upgrade of rod bolts.

 

damn thats noce to know so whats your setup looking like?

 

it looks like next race season im stepping up to the lsx block and a turbo I wanna see 7's in the quarter

 

sounds good what are you running right now?

 

so what will i need to do to my block b4 installing the new parts

 

Hone the cylinders for the new pistons, clean and deck the block, and turn the crank. I vote Wiseco pistons.. That's what I ran in my setup and most people on here will recommend them. Diamonds are alright too though. Top seal rings for nitrous. As far as rods, I went with Eagles w/ ARP 2000s. All depends on what your budget is. Oliver's are your best bet if you can afford to drop a grand on rods, lol.

 

i wish i could drop a grand on some rods but i cant right now i got a baby on the way and i need to get my car running good and hard b4 the summer rolls around. my car has been sitting in the driveway for like 8 months! really suck lol. but are you spraying?

 

not yet..... lol.. I'm still on a stock rear with a 6 spd.. I need a FAST 92, clutch, and rear before I'm ready for juice.

 

Definitely consider the Diamond or Wiseco pistons. They utilize the 2618 forging needed for that kind of nitrous use! I'd also go with the steel top ring set. It will help dissipate the heat better than a standard plasma-moly ring set! The ARP2000 rod bolts should take care of this one, as we've pushed them beyond 100rwhp on numerous builds without issues.

Let us know if we can help with your selections any farther!

 

What is cheaper?? Buy a new forged 347 short block from TSP, or buy the rotating assembly and have your existing block machined...

 

I'v got a 347 with Weisco pistons & Callies H-beam rods spraying s 200 shot no problem!

 

i cant wait to start ordering my parts i just need a little more money!

 

You mean 1000rwhp for the ARP2000 rod bolts?

 

I spent $1600 getting my block machined, crank turned, new bearings, bottom end assembled, and cam degreed. Eagle H-beams w/ ARP 2000s, Wiseco pistons/rings, oil pump and double roller timing set was about $1500. Plus your misc. gaskets.

So it's probably about the same either way other than the freight shipping. I would probably go with the TSP short block if I did it again just because everything is new and it saves the a lot of trouble.
