About to buy the Trex to throw into my 00 ls1 but had a couple questions with everyone else doing this swap... wat did u guys change out? i plan on going with the patriot extreme valve springs, and the whole package tr offers. im also gettting the ls6 oil pump, extra locks, front main seal, water pump gaskets. replacement timing chain.
wanteed to see wat else you guys would recomend.



thanks.

 

where is the best place to get an oil pump, i get employee discount at gm so i was ordering everything as far as parts throught them. but i dont knw if i should go with a ported one or what.

 

Ported LS6 pump.

 

get the ls2 timing chain, not sure if thats what you meant by replacement. Everything else looks good, i assume new pushrods are in the package youre buying

 

I just put in the cam, patriot gold dual spring kit, TR hardened pushrods. Kept my stock timing chain/oil pump. Still have 60psi at idle.

 

how many miles tho. and u already have the ls6 oil pump....

 

FYI... the locks in the Extreme kit aren't the generic ones, they are IIRC Manley Super 7 locks, not standard GM spares. At least this was what I was told when I asked Gunnar about getting spares. I have the same spring kit and couldn't be happier BTW. I have the Melling pump, speed inc had a sale I got mine for 140 shipped. Good luck on the swap.

Doesn't TR recommend to flycut the pistons with the T-Rex?

 

IIRC he posted about that and was told to sink the valves. I thought TRex was a max effort cam only cam, but it was said that the PTV even though flycutting isn't required, is pretty tight...

You dont need to flycut with stock heads.
Buy ported LS6 Pump And LS2 TIMING CHAIN from TSP >>>>>>> Sponser.

And since you are an M6 get 4.10 or 4.11 gears my friend ran that cam with stock gears it was slow as hell but then he installed the 4.10 the car made 399rwhp with stock tune.

 

push rods and springs. stock pump and chain. ill be doing them when the motor comes out though along with rod bolts. doing 4.56 gears with my 9"

 

I just got the cam package from TR.

Video of first startup in sig, btw

 

That **** is BADASS!! So much, for hiding that ls1 in the rx7 haha.

 

How about you call up thunder and get everything from them and get their advice on it since its their cam. Or better yet, why dont you just pay patrick the 25 bucks and get a custom cam ground up?

 

Engine had 40,XXX miles on it when I did the cam swap.

 

ya im just going to go with the ported ls6 oil pump and ls2 timing chain and all the gaskets and seals to go along with it.

 

they said just leave everything stock. which i dont like doing and b/c im already down there i mise well replace what needs it. b/c thats how i am. and i dont want a custom cam. i want the trex.

dont get me wrong patrick g is one badass and I KNOW he KNOWS wat hes doing.

 

I hope your rod bolts can take it, as your going to have to spin that sucker pretty high to get max potential.

 

or just upgrade the rod bolts....
power rang for trex
3500-6700......

 

You can do that... But, I think there is still some HP left on the table when stopping at 6700..

Shoot, my X3 cam levels out at that.
