I'm running a GT3076R around 20 psi. Bottom end is a Darton sleeved B18c1 with Eagle Rods and Wiesco Pistons. Head is a B16a2 with Manely Race series valves and springs/retainers kit.

Compression should be around 9.3:1 and I will be using a Water/Meth injecton system. Going to be tuned on Hondata s300 with Injector dynamics 1000 cc with a upgraded fuel rail and adjustable regulator and 255 Walbro.

I want to keep it under $400 and I found these options in this price range:

I don't know all that much about camshafts, but what I do understand is less duration is better for boosted engines? Can someone advise me on what would be the best choice for the most power, I am hoping to reach 500 WHP.

Thank you!

 

No. Its the opposite, you want a bit MORE duration for camshafts

 

Ok.... any advice as to which of those would suite me needs?

 

None of the ones you mentioned.

 

Iirc turbo engines like high duration and little to no valve overlap between intake and exhaust, right?

 

For a price range of $400max, I'd go with the Edelbrock 4730 cams or a used set of GSC T1 cams.

Then again, if you're only looking to top out at 500hp, stock GSR and Type R are more than enough.

 

ITR's

 

I may have found some CTR cams! Thank you for the responses. Finding the right cams has been difficult. Couldn't have done it without help and I appreciate it!

 

IMO Itr or ctr, no need for crazy aftermarket cams

 

Well I want VTEC to sound evil and since I built my head I need something a little more aggressive! Waiting on some Skunk2 tuner 1 now. Found a better deal!

 

If it's sound you want then you're going at it all wrong. Just cuz you have a built head doesn't mean you can or need bigger cams for your setup. Your build and turbo setup have to work hand in hand. I learned this the hard way years ago when i was still on a Greddy turbo kit. Just like you I wanted loud vtec with boost. In the end I couldn't make power, kept having valve issues, etc. I eventually ended up trashing the head. I built another head to same spec but downsized the cams and that fixed everything. My cams were too big for the Greddy turbo, and I think too big for boost at all. I was a noob and learned the hard way, so take my mistakes as a warning. I'm now on a different build but still using the same cams on my current setup. I'd switch them out for other cams to better suit my goals but they still currently work for my setup, not a necessity at the moment, and I'm broke. Don't think bigger is better cuz it's not when it comes to boost.

First and foremost, I'd definitely consult with Mac or Derek to see if the Tuner 1s are too big for the GT30R.

 

I agree and will take your advise. I just want something a little better than gsr cams. The skunk 2 tuner 1 is similar to the itr/ctr so it won't be too much crazier. Just a nice little performance boost that'll scream for me hopefully. I was told GSC is my best bet but I can't afford them. So I'm sticking with itr/ctr or something similar. The last thing I want to do is ruin my head!

 

my vote is gsr/itr.

 

I ended up buying some Skunk2 Tuner 1 with 8k for $350
