So you are spinning a stock 4.8 to 7500rpm? I assume you have rod bolts at least right? That is a healthy RPM.

Your next project should be this combo into a car that is yet another 1,000lbs lighter and has better aero. RX-7

yes it has rod bolts, dual springs and double roller timing chain. it has seen 7700 quite few times and has shown no signs of any harm. Ill pass on the next project im tired of personal ones. However there is another 4.8 turbo setup in the works and it will be in a mustang. So that could be another 800lbs lighter hopefully

Nice work... is the Ls2 better than the Ls6 intake for boosted engines? And are the log style manifolds better than the tubular ones? Very interested...thanks

got some work done on the manifold today. whats left with it is, i need to add the 90* bend with vband for the crossover and then finish welding the 90* that holds the T4 flange then its finished. specs on the manifold are....2.5" main tube with 2" primary's, 7/16 thick header flange {purchased from GM performance parts}







to some wondering why i used this style, it works well even tho it doesnt follow alot of ppl's beliefs on how a hot side should work. Similar manifold on this same combo in my silverado netted 702rwhp with a pig rich AFR and 16psi on a 4.8

in NA application the LS6 seems to perform better. In FI i dont see much difference. Ive had a 90mm TB from previous combos and bought the LS2 for 200 bucks new. I prefer the 90mm for air coming in, thats my theory others have theirs. My setup works pretty well for being what it is.

well the Ohio boys has set the bar pretty high with a stock manifold and compared them to the tubular and seen minimal to no gain in spending the money on the tubular.

the log seems to work for alot of ppl and being its made from sch 40 carbon steel you wont have cracking issues like you would have with tubulars. Plus being as thick as it is it will retain the heat like stock manifolds.

holy crap sch 40 carbon steel. you could drop that off of the strosphere and not have any cracking issues. Why did you choose sch 40 carbon steel over say 16 SS or sch 10 SS???

1st reason...got the material for free
2nd reason... its same setup as the manifold for the truck i had
3rd reason.. stainless becomes brittle after awhile vs the CS

biggest is the cost, you cant beat when things are donated. Plus the CS will hold the heat much better
