ITR head or GSR head

I was planning to get either a GSR head or ITR head on my LS engine. Which would be the best choice.

Are you upgrading the bottom end at all?

If you must, I'd go GSR. Its better for the cost if you look around.

Howdy, Guess who?

im going to be upgrading my bottom end. so which would be better? question i wanted to ask also.:icon16:

i am going to upgrade my bottom end. Which head would give the highest hp gain and would be more reliable.

I guess the most reliable will be going with a GSR. You can always add ITR cams, dual valvesprings, titanium retainers, race valves and port/polish (overbore). Whatever... later.

The GSR will serve the purpose best if you want the ability to start from scratch and customize your valvetrain.

The ITR head is just a completely sweet set-up if you plan on going the Honda JDM Parts route (ITR or CTR internals).

If you just want the "look" either buy a new valve cover for the GSR or paint it.

if i were to go turbo which head would be best

if i were to go turbo which head would be best

how about the one you have on your LS now! dont spend the money on getting vtec right now if you want to go turbo.. go turbo on the LS.

When I think about someone spending the money to go vtec on a non vtec, I think they want to do some serious N/A work. BUT if you are simply doing it for better flow for a turbo set-up tweak out the head you have on your LS...

so i should just spend my money on a bigger turbo...

Good god man! what do you have? what are you looking to spend? what do you want your car to be ablre to achieve???? I have nothing to be able to give you actual advice on only what you give me so lets expand on that first....

If you are thinking of doing a LS/VTEC setup then stay away from turbo! And if you are wanting N/A then get a B16 head it is cheaper and flows better than the GSR. The B16 head is the base that Honda started with when developing the B18C5 head (type R). If you are wanting to go turbo jus spend the money you would have on a new head and have yours port and polished, and some good turbo cams if the budget will allow it. Upgrade the internals and possibly sleeve it if big boost is you goal and boost away.

What would be wrong with the LS/VTEC turbo'd? Is it mechanical, or financial? Just curious.

More financial IMO. Think about it like this you will spend money on the VTEC head and then more money on an ecu, wiring,etc. When all you have to do is get the LS head port and polished. Maybe even some turbo cams and you will produce just as much power for less money. That is my feeling towards it anyway.

^ Hell yes! The fact is not all heads are created equal and yes Vtec is way cool to have on your LS. But you should not bother with switching over ($$$$) to Vtec if you have an LS (unless you plan on going straight up N/A). The LS head has it own qualities to play with. The LS engine is poised and ready to get a turbo and the head has so much room for improvement by simply boreing it out. It will be less work to just port the head on an LS and also you will get more precise tuning for your turbo. The vtec is really a feature that is for high reving RPM's found on a N/A car. Most turbo'd engines are to be rev'd past 7k-7500 and vtec is ment for making sure your engine (head) is properly functioning at intense RPM's from 5k to.... well the sky is the limit if you have really tuned your head for N/A but lets say 8500 (9500 perhaps <my goal :)>)
