Phil Grabow stressed this issue when W1 and Phil were doing my build.

Thanks. what valves would you recommend? going to call garret and talk about this today.

Ya im starting to lean towards getting a mild p&p. this is starting to get way to expensive!

Call up Ron at Raw Performance(used to be Axis). Home
He is the man to talk to about anything engine related. He does amazing work. One of the only people I trust with motors and heads.

Yes call Garret. Great guy and the entire team including Phil G. are top notch. We went with Crower intake and exhaust valves. Tell Garret you spoke to Matt M..

This would almost be identical to my setup. Built bottom end, stock heads with cams, but i have the element gt75 kit which makes no more power then the 65 without head work. You will be very happy with this setup, on pump and meth i made 492 whp and on race gas and meth i made 546 whp on a dynojet. The race map has gone 10.83 @ 131 mph with room for improvement.

I am going to be running a big rotated turbo setup. (Element Gt65 kit) I will be around 500whp give or take on pump+meth. Just wondering everyone's thoughts on my setup, and how solid it is? I am debating getting the heads done, but my engine builder says they dont usually do the heads on a street car. By street car I mean canyon runs often, and many track days, but I have a daily driver. Is my engine ok without heads? By keeping the heads stock am I making the turbo work harder?

no. you are just not taking full advantage of it at the top end.

Just wondering if the stock heads with this kind of setup is detrimental.

not at all. it's easy to get macho with headwork if you have the cash but it's really stupid. extensive headwork can kill the fun factor in a street car.

your current plan is solid but, if you really don't mind spending the money, you can bring out the full potential of what youve invested in your bottom end and that gt65 kit with some modest additional work. consider it a crime of opportunity. you are already doing doing arp studs and the springs and retainers, which is the absolute minimum you should do.

- do a stage 1 p&p while you have the heads off. you don't need valves. you don't need cams but, once again, if you have the money and the heads are off you may want to consider a nice set of stg 2 or 3 avcs cams.

- if you are adding the a1000, you might as well do it right and add a 2 liter surge tank with it in the trunk. you can get one directly from element. also consider the aeromotive fuel pump controller; it's not necessary but it makes the pump less noisy at idle and low rpms. phil can give you the parts list for the fuel system. it'll cost about a grand but it'll be worth it. you can turn the car upside down and you'll never run out of fuel. i am not sure you need 1150 cc injectors. 1000 cc sounds right to me.

- you don't mention em but with what youre doing you should consider hydra.

- loose the cosworth head gaskets and do the oem gaskets. phil just had them on his most recent motor and ended up loosing a head gasket at 150mph then hydrolocking and completely destroying his motor.

He is already doing Cosworth cams along with the springs.

[Neanderthal Racing]

so he is...proof positive of human fallibility.

Neanderthal- I'm going to be running Hydra em + Hydramist.

Have other people had problems with the cosworth Head gaskets?

i don't have the answer to that question but, i personally see no need to change from the oem gaskets.

[FlyingPerformance]

Who makes the Cosworth gaskets? Are they cometic or is it another manufacturer? The only head gasket problems I have ever heard of where with the cometic's blowing due to high boost. The OEM gaskets seem to handle the high boost just fine.

Cosworth makes the head gaskets, dont they? im debating just using the stock head gaskets..

Use new OEM head gaskets. They work GREAT.

Agree! Mine see 30+ psi on a regular basis with no issue so far.
