ok well im planing on ordering the TSP stroker rotating assembly, but a little unsure which pistons to go with. I've emailed them about 6 times for the last 2 months but yet to get a reply so i figured maybe some one on here could point me in the right direction.
my goal is around 700whp going twin turbo
Eagle forged 4' stroke crank
Eagle H beam rods with ARP 2000 rod bolts
Wiseco Pistons***
Plasma moly rings
clevite bearings
24tooth reloctor wheel
balanced

now as far as the pistons go i get to chose from either - -3cc flat top,
-8cc dish,-15cc dish,-32cc dish pistons, im using 243 cast LS6 heads which pistons will work best for up to around 20psi of boost, ive been googling it and all but cant seam to find some sort of guide to compression ratios for the diff spec pistons just hoping some one can tell me what compression ratio the diff pistons would give and which is best for a boosted LS thanks

 

maybe you should reconsider.. do you really want to spend money at a place that does not email you back..esp $3k and up... does not seem like a good idea. Of coasre bad service seems to be the norm now days rather then the exception... how i miss the old days when you could just buy something and know it would be taken care of, right, the first time

 

I would agree with you except for the fact that they've always seemed to take care of everyone I know. That has me wondering if their spam filter isn't working so well. OP, I don't know why you would wait 2 months for a reply without calling them. Trevor and the boys over there will be happy to help you I'm sure. Give them a call.

If you don't wish to call them, Send a PM to Trevor @ Texas Speed
They're a premium vendor here and that's your best bet for not hitting their junk folder.

 

^ thanks for the tip i was kinda hopping on of them would see this post, n as for why i don't call I'm deployed over seas in iraq lol so emails about all i have i get little to no phone time each month n when i do get it i call home n talk to family lol
and thats exactly why I'm considering using them even though they don't call. I've heard nothing but good things about TSP and they come highly recommended from every one i know with an LS motor I've even done some work with there parts at the shop at home there stuffs always top notch

 

I apologize that you never received a response. Please PM me the people you have e-mailed at TSP, and I will find out what is going on. It is certainly possible that it was pushed directly into a spam folder. Sometimes it will do this with customer's e-mails for no reason!

For the power you're looking to make, I would recommend the Callies Compstar crankshaft and connecting rods. We have pushed these parts past 1,000 RWHP! You can spend a little more now or a lot later. The Wiseco pistons are an excellent choice. They come standard with a steel top/napier 2nd ring pack that works excellent for power-adder setups. The steel top ring will take a lot more heat than a standard plasma moly top ring, and the napier second ring will scrape the cylinder walls better, allowing for better oil control. All of the Wiseco pistons have nice, thick crowns that allow for high horsepower applications. The wrist pins that come standard will handle up to 1,200 flywheel HP, and they offer a tool steel wrist pin set for an additional $140 that will take you beyond that goal. I didn't see where you had mentioned engine size, but I am going to assume that you're looking to use your existing LS1/LS6 block to build a 383 C.I.D. I wish Wiseco would offer a -20cc dished set like they do for the 4.03" and 4.07" stroker setups. That would put you in the low 9:1 CR range. The -32cc dished setup will net a very low CR, 8.55:1 to be exact. This is assuming a zero deck setup (i.e. the piston is even with the deck at TDC) and using a .040" thickness Cometic head gasket set. If you go with the -15cc dished pistons, you can get to 9.63:1 CR using a .060" thickness Cometic gasket. This is also assuming a stock 243 chamber size of 64cc. You don't want to do more than a clean-up mill (typically .003") on the heads since you'll be boosting it. Milling the heads significantly can lead to issues with lifting heads and blowing gaskets under boost. If the budget allows, you may consider a set of aftermarket cylinder heads that offer a thicker deck surface. The Precision Race Components 227cc heads would work excellent on a boosted application, and they offer a thicker deck than any of the Trick Flows. They also outflow and outperform the AFR 225's by quite a bit. It would also allow you to have a lower CR of 9.27:1. No matter which cylinder heads you go with, you'll want to consider race gas and/or methanol injection when you start chasing the higher boost settings. As a general rule, you can typically run 12-13 psi of boost on 93 octane pump gas with a static compression ratio of 9:1. So, if you have a CR of 9.6:1, you'll be able to run around 10 psi of boost on pump gas before having to consider other sources of fueling. The 8.55:1 CR with the -32cc dished pistons will be very low, but it does give you more room for boost on pump gas. It really comes down to personal preference and how much boost you want to run on pump gas. The higher static CR will produce more power, but that's not going to be much of an issue with a turbo system. I would certainly recommend an ARP main stud and head stud kit, as well as Cometic MLS gaskets for the setup. They will be a great choice for a power-adder setup.
