GTSR Heads? Anyone have any information on these

[slitherv10]

Have a friend who has some GTSR heads that he may want to unload. I have a 96 GTS with smooth tubes, Mopar performance computer, K&N Filters, Oreca wires, belanger headers, no cats and borla exhaust.

Anything special about these heads and what should I look for as far as flow numbers, HP gains etc...any information would be appreciated.

How can I tell that they are GTSR heads?

This might help you, VPA had a set of GTSR heads for sale, the advert gives you an Idea of what you should be looking for

Did a search on the VCA website for you.

A wealth of info. is available on Gen II's

At VOI 12 they had the ported set of GTSR heads on display. They looked like they should make big numbers, but by all accounts, they don't make much power in a street application.

Exactly, these heads were designed to run at full throttle. They will not perform well on a low RPM street driven car.

Bought a set of cauldwell GTS-R heads from DC performance bolted straight and work great on my roe RT/10...

How would they work on a street version non SC car? As stated above, the GTSR heads are only good at wide open throttle?

Like I said, there is plenty of actual info. on the other site. You don't have to speculate.

Speak to Gregg good, he would be your man in the know......

They work great on my Viper very responsive.. Even Chris Jenson was impressed...

Do you drive your car a lot? I put about 5000 miles a season in hot weather. I would need to know the heads and the set up with a cam or what not will be reliable enough for someone who puts mileage on his car. I am not a track guy so if these heads are made to suit the track, they wont be for me, but, if they can be altered and be better in the end than stock ones I have on now, bingo!

IIRC, they are a great head to modify.

Would it make better power or what not over me modifying my originals? Keeping in mind I have to fork out the money to buy them and then modify them or save my my money and modify what I have and put that extra money into something else that may give me more bang for my buck

Call Greg Good and ask him. He's worked these heads, all heads and can you give the details you're looking for. Prepare for at least an hour on the phone with him and take notes.

Funny you bring that up. I was just looking back at one of our messages we exchanged a while back and looked for his number which you gave me and called him just a few hours ago. It will be interesting to see his decision over using my own heads or buying the GTSR ones.

He won't make the decision for you but arm you with the information you need to make your own decision. He's getting ready to work on my engine, I'll tell him you called.

Work on your engine.....oh no!..forget it. he has no time considering he has to start on my heads.

IIRC the gtsr heads have more room to modiy for big power over the OEM heads. I dont think in your case its going to help since you are not looking for crazy numbers. But as GG, he knows them well

I don't use my Viper that much but no track use all street

So do you think you drive it enough to confirm that these heads are great for street use or is your driving time not enough to say they are reliable and work great for the street?

They work fine for me ..Done a few long trips and cruises and get low 20's mpg (UK Gallon)

I ran GTSR heads on my old World Challenge Gen 2 road course car. The car made 630 RWHP; then I cracked one. I put the Striker Stage 3 heads on it (with all the good reciprocating hardware) and the car made 635 or 640 RW. Its a pretty positive statement for the power the GTSR heads can make. The power is indeed much greater at high RPM's though the engine has enough native torque to pull itself around at lower speeds. You just don't get that sledgehammer torque at 2500 RPM like you do with most street heads.

Greg Good is the man on this stuff; axe him!

We're your GTS-R heads worked or as-is?

update:

These turned out to be regular Gen 2 heads with some ported polished with valves and what he said were manleys. Going to get them flow tested tomorrow and see the numb

[Dan Cragin]

GTSR heads were a unique casting, it depends on how they were prepared. The race heads had very small chambers and only worked with custom pistons with correct valve reliefs. These same castings were often modified for street use, you need to get the specs on the heads.
