hey what's up? i've been reading up about boosted ls's, and what i seem to be reading is that a stock ls head has trouble making power past 6200rpms. so the theory that i had was that can i mount a gsr head on my ls and not hook up vtec? this way the head will still make power in high rpms like 7500 or so! No my question is will this work or just port my head cause a can get the head for prob. $300 from one of my boys, what do ya think?
I am also runnin a gsr tranny so if i could rev higher that would be great. thanx

why teh hell would you put a vtec head on and not run VTEC?????!!!!>?????

just hook up the vtec and you will make so much more power.

i don't wana deal with cr's and have to run return oil lines and whatever else. i figure if i tune it i can take that head and make power to 7500rpms. i wouldn't think about it but i can get a pretty mint head for real cheap.

That is what went through my mind when I read it. That'd sort of be like shooting yourself in the foot haha. If you don't want to run vtec because you don't want to buy another ECU, then stop those evil thoughts Just hook vtec up....huge gains are made with vtec (proof: I, for one, made an additional 138whp more with vtec).

Plus only 7500RPM's in <U>any</U> honda is not going to cut it. They are not torque monsters, which is why you need to rev higher then 7000 or 7500.... (or have vtec).

What are you talking about? You wont have to run any oil return lines....you need oil feed lines. Second if you mean compression ratio by CR im confused because the compression doesnt change in vtec.

i'm sorry if i sound like i know what im talking about cause i don't i'm clueless when it comes to vtec. i was under the inpression that i would need to run oil lines change ecu pistons ect. but idk that is why i'm asking. So it wont work?

b18bEKcoupe

oh, it would work but you should also hook up vtec. The head will slighly raise compression with or without vtec hooked up. You do need to run one oil line but its no hard and you dont need new pistons. The ecu however will either need to be chipped and have vtec circutry added or you can just buy a new ecu.

so your saying put the head on and hook the vtec up? I just set up the turbo on my ls. i picking it up to night but i might tell him to keep for a couple days and hook the head up? but will it be as reliable as my straight lst?

b18bEKcoupe

if you do it right it will be reliable. There are a few things that you need to work out first. You will need new dowel pins because the head and the block use different diameter pins. You will need an oil line that connects from an oil supply to the head and you will need to drill and tap the head for the line. It can be just as relable but it takes a little work. It really seems more complicated than it is. Check on ebay and golden eagle has kits that include everything you need including the head gasket. You might need to run wires for vtec to the ecu and you will need to decide what you are going to do about an ecu be it chipped and modified ecu or a vtec ecu.

that sound easy enough thanks for all the help guys. i will talk to the ******* working on my car and see what he says. Hes kind of a tool. he is perfect with his car and doesn't really givae a **** about mine i should get ithe car back today ( i hope) i will see if the power loss at 6000 is as drastic as everyone says if so vtec here i come!!! LOL

If you do put the vtec head on remember that the bottom end wasnt designed to be revved very high. So i woudlnt go much beyond 7000 rpms unless you had some work done to the rotating assembly. Maybe you should look into having your head ported and polished and then throw in some new turbo cams and springs.

that is my next step valve train i just have spent so much money on this car like 20 grand so i'm trying to get sponcered but either that will be done shortly

search for the word "LSVTEC"

Because thats what the format that you are going to do is CALLED!

Don't be an *** when people are trying to help.

And if you want the motor to last, I believe you'll want to do work to the bottom end (arp rodbolts, and arp headstuds) before you even think about head work.

GE has a nice kit also... to make the conversion simple. HG, dowel plugs, oil line for vtec and all.

i don't know if i'm donig the lsvtec that's why i said "y" not trying to be a dick!!! thanx for the info. i haven't driven the car yet i'm looking for 270whp for the time being that should be fast enough for now!! LOL
