Ok so my question is ive seen a billion camshaft threads but im seeking opinions from experience dyno proven. No cousins sisters exbf used these cams bs. Im shooting for 15 to 20 on stock sleeves whatever my tuner (very reputable) decides to go with safely.

So far I know the pro1s are a great turbo cam also looking into the gsc t1 cams. Does rocket motorsports produce a better turbo csm for my goals? Any experienced opinions highly welcomed. Thanks guys.

 

For that power level, anything bigger than the ITR/CTR's are going to be more headaches than the gains are worth.

Keep it simple, use OEM cams.

 

For your HP goals GSR, ITR or SK2 Tuner 1 cams are some other good choices too. Pro1's are good as well, but then you'll have to mess with degreeing them as there not a true drop in cams like the other ones. Also for your power goal they just may be over kill. One thing to mention your limiting factor will be your stock sleeves. You dont really want to push them over 450 HP on pump 91 or 93 octane.

 

The Pro1's are too much cam for a car using a turbo with under a mid-60's lb/min flow anyway.

 

The ebay 60 trim isnt going to get you to that hp goal. They're 60 trims arent going to flow like a garrett 60 trim.

Stock cams will get you to that power level and maintain oe driveability. If you want to run pro1's or gsc cams your going to need a turbocharger that a minimum of 65lbs/min or 61mm and up and the right sized turbine wheel and housing for proper exhaust flow otherwise they will do more harm than good in power production. Your running a quality ramhorn so that shouldnt be an issue with the larger cams. the 3076 wont do very well with the gsc or pro1's. I personally would stick to gsr, itr cams for that power level and turbocharger.

Stock sleeves can and are frequently pushed way past 400hp. Hell we've pushed boen stock gsr motors to almost 500hp on ethanol. Plenty of peopel running stock sleeve blocks 600-700hp and they hold up well. They all seem to run a blcok guard or the new css but most around me run block guards and are pushing their blocks hard without failures. Its all in the tune IMO

 

I would definitely go with typers. Cant go wrong, great driveability.

 

GSC n1's

 

Don't waste money on cams. I've done 400hp on a bone stock b16 oil pan to valve cover. It had injectors, fuel pump, log manifold and a eBay 57 trim on e85. With your parts 450 would be easy with gsr cams. As everybody else said don't go bigger than tuner1's or itr's if you are getting a good deal on them.

 

^ agreed!

My setup made 435 on pump with GSR cams in it, had Pro1s in it and made 410 and took more tuning that it was worth to get the Pro1s dialed in.
Gsr cams were easier to tune, made better, usable power and are made overall street drivability better too.

 

Save your money for a better turbo.

I make 500 with stock GSR cams, rail, IM, TB and head

 

Ok im seeing a lot of mentioning e85 tuning. Thats not an option for me there is no e85 pump anywhere near where I live. 92 is the best we have. Sounds like oem cams are good for my power goal. But what if I went a larger turbo say 35r? Keep in mind the build isnt in the books yet. I thought 400 to 500 was the max I was going to be able to achieve. If I can hit more so be it.

 

I installed some edelbrock 4730 cams from ipg. I think he sells them for under $400. had them laying around the shop. on a 3431e/57 trim they didnt improve peak hp (same boost)but I think thats a back pressure issue, but what they did do was 20-30 hp and tq from 5000-7500 (on 2psi less boost) and 200 rpm better spool. making the power band look great

 

green is new cams blue is gsr cams. boost is plotted on bottom

 

^^^ Nice gains there.

Going with a larger turbo can get you your goal on 92 but you lose spool and midrange power as 808 shows above. Unless you want big power, don't get a big turbo. Run the appropriate size turbo for your power goal and run a water meth kit if using 92

 

^ exactly! Gt28 (Or similar sized turo) would be a good fun, moderate power level turbo for your goals.

 

X2

 

ive been using itr cams for the past 4 or 5 years in the 400-500whp range. i am beyond pleased with them. they were easy to tune and my out of boost driveability is like stock. i see 30-34mpg from my 2 liter b series when just cruising or on the highway.

i would run them on aftermarket springs and retainers though, maybe the 70lb supertech's for example.

 

my vote is itr. if you already have gsr cams use them, spend your money other places.

 

For what its worth...

I had a guy i was tuning for running CTR's, PTE 5757, 2.0l, 9.5 to 1, BRM ramhorn, and made 460 on pump. We switched in Pro1's and had them set at 0 and made 506 at the same 19lbs. His goal was anything over 500. We could have turned it up and made the same 500 on a little more boost. But he got a smoking deal on the Pro1's so we figured why not. did lose some mid range HP and only picked up 15 or so more TQ.

 

I've seen plenty of builds making into the 600's on gsr cams my vote is OEM for your goal (as far as cams)

 

They are a little more expensive now, but IPG still posts their package deals.

GSC T1 camshafts can work very well on GT3076R turbochargers that run decent pressure (above 17psi) and have been shown to work quite well contrary to popular opinion. I have found that the 61lbs/min requirement was not the case as I initially surmised over a year ago. that was when i tried them for myself on my TR3030R (A GT30R derivative). But they WILL NOT work with a 60 trim eBay special well at all. As others stated, in your case, please stick with the OEM for these particular goals unless the goal is for a better overall torqueband. Then you need both a better turbo and turbocharger camshafts.

 

548 whp 24 lbs 81.5 basic set up with itr cams!
You can get away with these. My tunner said we still have room to turn up the boost into 600 with my current set up. That the itr cams and Stock sleeves!

 

My vote Itr/ctr cams. I have them and I'm at 420whp on pump

 

Wow I didnt expect so many replies. Thanks guys. I currently have no cams. I had a buddy pry the blox cams I had out of my hands for a good price so I guess ill keep my options open leaning more toward itr cams or a mild aftermarket. Is 500 really a reasonable number on pump? Seeming to hear a lot of stories of it but id thought it was crazy talk. The car is an ek hatch weekend warrior summer days kinda car. only racing it will ever see is straight line. Thanks for the supportive responses!

 

Ive tuned several cars on pump gas that have made over 500 reliable horsepower on pump. cars that have lasted for years on it at that power level. 500 is a good number for pump. But not much more.
