hks are great cams, but they are very mild compared to other cams available. HKS cams shine at low/midrange power more then they do uptop. They will help spool and mid range power more than anything. Good for autox'ers, not good for drag strip.

 

well yeah thats all good..but i have a set of hks 272's with me but are not installed on the car yet?...im on a stock turbo and use my car as almost daily driven car and jst street racing...nothing else..
so do u guys adivise me to sell me hks and go for gsc 2 or kelfords?....

 

go with kelford for the more aggressive cam. this was proven in the ams testing.

 

everyone seems to talk abt the AMS cam test ...but what nobody takes into account the kind of setup the car was running...35r, ams built engine and what not.....
and everyone around the forum follow that test and no one takes into account the fact that if i use cams i will be putting them into a STOCK car with jst some bolt-ons added to them..?

not to mention the bad loopy idling when you put such aggressive cams on the stock turbo...

 

If you're using a next to stock setup then just throw the hks on. the more aggressive cams are more for larger turbo setups that make all their power uptop. I had HKS on my fp red and i was seeing full boost at 3700-3800rpm in 2,3rd and 4th, 5th around 3500 rpm, it felt like a 16g turbo the way it spooled. You'll get more power out of the other cams, but the hks will give great mid/low range power that those cams wont be able to compete with.

 

yea so that means hks would be perfect if im only doing street races...and a daily driven car...because the kelfords or GSC's would jst be too crapy to drive everyday plus i loose my early spool...is that correct?

 

not necessarily no. the kelford could effect spool slightly but i doubt gsc's will. you'll make more power with gsc or kelford but you wont be getting your moneys worth powerband wise since the stock turbo will stop making power very early. you already have the hks just throw them on and see how you like them.

 

+1 just try the hks cams i have had my fp green for about a week and i am using the hks cams run's like a dream i thinking of selling green and going red or black

 

+1 for HKS cams if you want to stay with the stock valvetrain. I have HKS 272/280 and I'm making 520whp in 80 degree weather. They are clearly not holding me back.

Seems like a few of the guys running the FP Red in this thread are on stock blocks. What is a safe psi to run on the Red on a stock block? Are people pushing these turbos above 30 psi om stock motors?

I'm in a similar situation as the op and have pretty much every bolt on available, but wasn't sure if I should build the motor before I upgrade turbos. Seems like you guys aren't recommending a built motor so maybe it's not necessary.

 

IMO, I dont think a built motor is worth it unless you are tracking the car on a regular basis and making around 500hp or more. You can have a sick street car on stock internals. Like others said, it depends on how good of a tune you get. But, just because you have a good tune, does not mean nothing will go wrong when pushing the stock block to its limits.

 

^ I would like to add to this. I think 600hp is max on the stock block as long as you keep the tq below 400. I plan to have my Red at 550hp next week and 425tq. I still think this is pretty safe. Torque is what breaks the OEM rods, not hp or psi. The stock motors are great and if taken care of will last a long time. They tend to blow once the tq gets over 450+. Food for thought.

The best turbo for the stock block is the Red. Hands down. It will create great hp and keep your tq low enough that it won't break **** and you still get full boost at 3700-3800 plus everyone likes to make 500hp. If you want a bit more power you can get the Black. One of my good friends has 520/417 with the Black however spool is 200+rpms slower than the Red. I may upgrade to the Black but for now the Red is awesome

Mikey you pushing 30psi on that Red without Meth or E85?

 

read his sig man lol all your questions are answered there of course he is on meth and 30psi lol

 

^+1 Ya I'm running 1500cc of 100% M1 meth. I could run 38+psi and have 575 but my tq would then be to high. That's why I'm only at 30psi right now.
