Default Building a non-AVCS 257, looking for road race cams

I have a complete 04 STi motor with 8.5:1 Wiseco pistons installed and stock STi heads without cams. I'm not using AVCS (engine management doesnt support it) and I'm looking to shift no higher than 7800RPM. My turbo will be an old FP Green.

Since you have the rundown of the build, here's what I'm looking for. I want to have a good, solid road race cam. I dont want something thats real peaky, or $2000 lol I'm looking at Cosworth and Kelford, other brands are options as well. Also, how should I go about plugging the AVCS holes in the cams? Can the be plugged safely or do I need to run AVCS cam gears?

Any insight will be greatly appreciated!

Thanks,
Frankie

I think Tomei actually makes a set geared specifically toward road racing.. Poncams or something they are called.. From what I've read, they are the same ones they use in their road racing time attack programme.

Kelford 264's or probably even the 272's (since you are revving it out a bit), would work great for that application. They make non-avcs cams as well as avcs cams.

I didnt see those listed on Vivid Racing and thats the only place I've seen Tomei cams. I didnt really get a chance to look around for them though. I'll check more tomorrow.

I thought so, but I just wanted to make sure.

I've heard alot of good things about them so thats what I'm leaning towards.

Anyone know anything about the Cosworth cams?

GSC, tomei, or JUN are your best choices.

I love my kelford 272 intake / 264 exhaust cam setup (10.5mm lift). It was amazing with a GT30R and still great with a GT35R but the TQ drops off hard at the top. With the GT35R setup I get 460 TQ at 4600 RPM at 24 psi, very nice coming out of the corners.

Kelford do a non AVCS cam which you run with non AVCS cam gears.

Next years setup I have gone big, 280 Intake with 11.5 mm lift, 276 Exaust with 11 mm lift. Had to clearance the head castings for the lift on these. Should be fun

So Kelford makes a 2.5L profile without AVCS?
