I agree go with a vtec head, When i built my LS i biult the LS head and should have put the money towards a si head, But if you wanna run a LS head PM me i'll sell you my built one.

I heard the LS was the official motor for Brokeback Mountain.

Vtec DOHC Head = $500.....LS Head= almost Free...LS Head + $500= Vtec head

I agree the Vtec head is alot better stock to stock...and yea you can say put that $500 into the vtec head and it will be uber times better yea thats true but for a budget build it really comes down to how much you want to spend...I honestly would rather put the $500(cost of head) + about another $200-$300 to do and LS/Vetec properly into building an LS head, not to rev high but to flow better...but there is the difference if you want to make 500hp+ get a Vtec head if not an LS motor could get you close to 500

BBKA, I'm sure you've seen the 295 whp stock block ls motor with the crane turbo cams. 9 psi at that, too

Jeff Evans tuned it, and it made a hella fat powerband.

well this thread has gone the way of every other vtec/non vtec thread. have i ever seen a LS head, yeah i have 2 in my basement, and one on my car. point is for me to do a vtec conversion would cost alot more. sometimes its easier to fix the problems with the non vtec head.

regarding the rockers look up "rocker arm stopper" by tomei or HKS for the sr20 motor.....

stock for stock yes vtec better but if your going to port the vtec head add aftermarket vavles/valvesprings and add cams then its kinda a moot point isnt it. your adding aftermarket parts to most of the advantages it had. its cheaper to work on LS heads when your going to do lots of other work anyway. theres not going to be a huge difference in a LS head thats been ported with oversized vavles and better valvetrain with a mechanical rocker arm stopper compared to a vtec head with the same mods.

i just wish people wouldnt talk so much ---- about the non vtec head. its more work but it doenst mean its a horrible decision. try, just try to be open minded and let people make decisions on their own not tell them they are stupid or gay for not doing what you are doing. give people pros and cons and let them make up there own mind. i think its amazing especially when d series people are the ones dissing on LS motors... you dont see me saying WTF d series is gay do you. of any site i would expect HMT to be more open since its a low budget site and the LS fits that bill. you can throw in a set of cams and valvesprings for less than youll pay for a vtec head alone and it WILL make comperable power so a stock LSvtec

Do you mean this car? http://forums.evans-tuning.com/viewtopic.php?t=1813
That powerband sucks *** lol. You get maybe 2,000rpms at most.

Here is a good powerband (3,500 rpms)... http://forums.evans-tuning.com/viewtopic.php?t=2993
This is a stock GSR head too! Very simple setup and look at the results.

I think this is the car your talknig about... http://forums.evans-tuning.com/viewtopic.php?t=790
Can't see the dyno sheet though.

wow thats a great comparison since the LS has stock cams and the GSR has crower turbo cams. find one with a stock vtec head and a stock LS head that has cams with the same turbo.
