with the mods in sig. what stage do you guys suggest i get?

http://www.totalengineairflow.com/pr.../gmhead/gmls1/

i emailed the owner and he told me a stage 1 but i just want to see what you guys think. he said it should be good for about 35 rwhp in my case what do you guys think it would yield?

 

Why did he say Stage 1? Did you tell him the cam you have?

 

Stage 1 is fine, I would also look at a stage 1.5 in the 5.3 heads.
Their stage 1 is better in the mid range and still flows great way past what the cam needs.
Stages are stupid in the head industry.
A stage 2 is probally the same exact heads but with aftermarket intake and exhaust valves. That is probally the only difference.

 

so you think the 1.5 5.3, would give more hp?

 

Depends on what stage 1 casting you were using.
A stage 1 LS6 would compair very well to a 5.3 stage 1.5.
Both will flow very well and increase compression.

 

I think you should go with TSP/PRC stage 2.5 heads(5.3's)

 

I think you should run the 1.5 5.3 at 11:1 compression and you will have a nice setup with better power and torque.

 

so many opinions....lol...thing is im on a budget trying to keep the head setup around 1000....im intstalling it myself so....

 

All the more reason to call Texas SPeed. They'll work with you on price for everything needed to do the change as well as the heads. TEA wont do that. Been there done that. Plus in a side by side test with TEA heads and TSP/PRC heads my car with a tr224 out pulls and fm13 car w/tea heads.
Money is important, you need to get your best deal. Call Texas Speed

 

Too many variables to put stock in an equation like that. Until the PRC heads overtake the ET's that TEA heads have been laying down since the LS1's introduction I would stick with them. TEA has been in the LS1 business along time and have their act together.

 

Your variables are not as big as you think. Both cars were modded almost the exact same and were done within days of each other under identical weather conditions by the same person on the same mustang dyno. One car is a 99 and the other is an 01 is the biggest difference between them. After all the bolts ons and mods they are very close. Tea heads are good but so are Texas Speed so you might as well go with the better deal. I outpull that fm13 w/tea heads by 20hp and tq all the way through the rpms up to 5800 and then it gets close at the peak. Thats all on a mustang dyno.

 

Go with TEA. i was trapping 117 in 4200' DA with a four year old set of there 5.3s. like ryan said until we see the PRC laying down the numbers AT THE TRACK go with TEA. i am not ******* PRC at all because they have been laying it down on the dyno but we i haven't seen too many track times.

 

While I appreciate what your trying to say your not correct. There are a lot more things that go into a good track time than a dyno run. Traction being the biggest of them all. If my car would hook has nothing to do with who ground the heads. You guys all say the same thing about cam shafts as well. The real thing about drag times is whether or not you get traction. Track times are indicative of the whole setup not the heads alone. Going with the best deal as far as money is what he should do here.

 

Lets face it, the heads are only one part of the equation not matter how you look at it. track time or dyno run. Heads are measured on a flow bench.

 

thats why i mentioned my trap speed and DA smart guy! heads have alot to do with trap speed. and before you start making coments again about set up, my car was full weight, all the bolt ons minus a fast intake. fwiw the guy was asking about TEA not PRC.

 

so i guess i should go TEA.....im thinking about just getting the stage one....i already have new 921 spring kit.....TEA said they will port my heads to a stage one and assemble it with my spring kit for 800$

 

I would say the TEA heads stage for stage are just as good or better the the TSP heads, HOWEVER, dollar for dollar the TSP heads are very hard to beat.
If 1000 is your budget I would look into TSP or Patroit.
They both offer a nice package for someone in your budget range.

 

550 to get them cnc'd by tsp and 600 from patriot.

 

man with the price of heads these days, you have alot of options...its just crazy you can get a head that flows 300+ cfm for 1k. aside from that, all those options of heads that have been posted/discussed, you really cant loose from picking one over the other, there all great budget heads. now with what your talking about and your question on what stage. i'd get the 1.5's....i have the TEA 5.3 1.5's and i have no complaints about them...there great heads. with there CNC program they have on them, there isnt much a difference since i last talked with TEA between the 1.5's and the 2.5's. the 2.5's just having a 1.60 exhaust valve over the 1.5's stock exhaust valve...i dont believe the flow #'s vary that much between the two. now, i dotn know if they have updated there CNC program lately, but last i talked with them, that is how it was....enjoy the heads there great..

Off all the replies on this thread, that is the best idea I've seen. Do it, no need for TSP's lol. Comparing TEA's to TSP's is like comparing a Corvette to an F-body. They're both killer, but the vette is just better.
