welcome to 1995. glad you could join us!
Now lets focus on the mods that matter.....

GSC S1s or S2s would work fine, so would Kelford 264s or 272s, or Tomei 260s or 270s.

I would just skip the billet parts in the turbo, they're pretty pointless. The stock 12cm turbine housing seems to make the most peak power on DSMs, and when put on a proper divided manifold, can produce some nice improvements in spool speed. Higher compression works too, don't be afraid to go 9.0:1 or 9.5:1 on E85.

I have a few Holset install parts I won't be using, like the 3" downpipe adapter, ExtremePsi -10an oil drain, ExtremePsi -4an oil feed from the filter housing, silicon elbow for the compressor discharge and a 4" coupling for the intake. Winnipeg to Minnesota isn't bad for shipping.

Bushur cams would be a better choice than the S2s. They would give you a broader power range and make more power throughout the whole power band.

I ran the fp2 and was revving out to 9k, the cams held the power until the limiter. The car made 580 awhp(Dyno Jet setting) on those cams using a s259ett at 30 psi. Just some food for thought there.

OP- Honestly there are a few cams that would work great for 500 awhp in a manual. Personally I would just find a good used set of s2's, fp2s, kelford 264(yes 264s)/272's, or some Bushur 272s. Searching the classifieds can save you a lot of money and still get the cam you need, I've picked up brand new kelfords for 300 and those FP2's for 220 shipped.

And one last thing, you do realize that those holsets are just waking up at 30 psi right?

The FP2 is the same as Comp Cams 101200, not GSC S2s. GSC's cams are proprietary.

A list I made of some of the DSM cam choices:

GSC, Kelford and Tomei's lift figures are calculated with a 1.73 rocker; HKS and BC use 1.7, so I equalized them to 1.73. I don't know what Jun uses, but I suspect a 1.7 (numbers unchanged).

**Keep in mind that the duration numbers are either measured at 1mm (0.040") or at 0.050" - you cannot compare these values!**

GSC S1 Lift: 11.0mm/10.5mm
GSC S1 Duration @ 1mm: 216/220

GSC S2 Lift: 11.03/11.03
GSC S2 Duration @ 1mm: 230/230

Kelford TX264 Lift: 11.00/10.35
Kelford TX264 Duration @ 1mm: 216/216

Kelford TX272 Lift: 11.00/11.00
Kelford TX272 Duration @ 1mm: 226/226

Tomei Poncam 260 Lift: 10.70/10.20
Tomei Poncam 260 Duration @ 1mm: 215.5/214.5
Tomei Poncam 260 Duration @ 0.050": 209/209

Tomei Procam 270 Lift: 11.50/11.50
Tomei Procam 270 Duration @ 1mm: 227.5/226.5
Tomei Procam 270 Duration @ 0.050": 221.0/220.5

Tomei Procam 280 Lift: 11.50/11.50
Tomei Procam 280 Duration @ 1mm: 232/233
Tomei Procam 280 Duration @ 0.050": 225.5/228.5

HKS 264 Lift: 10.48/9.97
HKS 264 Duration @ 0.050": 187/186

HKS 272 Lift: 10.48/9.97
HKS 272 Duration @ 0.050": 195/195

BC 272 Lift: 10.36/9.83 (Stage 2)
BC 272 Duration @ 0.050": 208/212

BC 276 Lift: 11.27/11.27 (Stage 3)
BC 276 Duration @ 0.050": 220/220

BC 284/280 Lift: 11.63/11.11 (Stage 4)
BC 284/280 Duration @ 0.050": 230/226

BC 280 Lift: 10.90/10.79 (old profile)
BC 280 Duration @ 0.050": 218/216

Comp 101100 Lift: 10.34/9.93
Comp 101100 Duration @ 0.050": 204/204

Comp 101200 Lift: 10.44/10.03 ***These are the same as FP2s
Comp 101200 Duration @ 0.050": 212/212

Comp 101400 Lift: 10.54/10.13
Comp 101400 Duration @ 0.050": 220/220

Jun 272 Lift: 10.62/10.62
Jun 272 Duration @ 0.050": 211.5/211.5

For an HX35, the GSC S1 or S2, Tomei 260, Kelford 264 or 272 and BC 276 would all work. For spool and torque, go with a 'stage 1' 264/268 cam (either Kelford 264, GSC S1 or Tomei 260), and the GSC S2, Kelford 272 or BC 276 for higher peak horsepower. Head porting is advised to take advantage of the higher lift cams.

Where are you getting this from? I ran the fp2 which is the exact same cam as the s2 and was revving out to 9.25k, the cams held the power until the limiter. The car made 560 awhp on those cams using a s259ett at 32 psi. Just some food for thought there.

yeah thats what i keep hearing about them, hoping to still make decent power at 30 otherwise ill keep turning it up and play with the tuning, cam choice is turning out to be my most difficult choice out of everything

Yea my mix-up on the FP2's and S2 being the exact same, they are indeed the same as the comp 101200. Fp2's/101200's are something you should consider if you can find a deal on them. Personally I would look for any of the suggested cams and pick up a set that you find a good deal on. Any of those cams described will work with the hx35 and get you to 500 whp especially on a FWD.

Comp cams are great. I have the 101300s/FP3s in my 2.4 motor with a 25g turbo and love them. also driven cars with HKS and Kelford 272s, both were good, kelfords made better numbers in the same car.

I'd also recommend installing a set of adjustable cam gears too. You can change the powerband to match the turbo better, or to suit your mood. For example, I have a set of Kelford 272's in my car. They make great peak power but trade off some bottom end. When I commute and do long trips I like to advance the gears by 4* for better idle, spoolup and midrange power. When I hit the track I like to retard the gears to -2* for max top end. Whatever cams you get, you're not stuck with one powerband, you can change it. Just keep an eye on the classifieds and see what pops up.

He mentions adjustable cam gears in his original post

looking into kelford 280/276 cams from real street performance, they look like they should do good with everything else.

Update still researching my cam choice lookin into kelford 264s also decided I'm going with an external wastegate off the manifold not the turbo so I can have more housing options.

I'm running a Ross/Eagle setup and Comp 101200's (Fp2) and I'm happy with the powerband. Quite a bit of midrange, the stock Intake manifold has alot to do with that as well. It's nice not having to drop a gear to to get the rpms up to make power. My old Laser had a JMF Race manifold and GSC S2's and it was absolutely gutless under 4,000 rpms. As soon as she hit powerband tho you knew it and it seemed like it never wanted to fall flat all the way to the rev limiter (9,200rpms)

I'm still debating on which manifold I want to go with looking into Magnus or a jmf

Any reason why you decided to go 264? people on a 14b or even a 16g use that small of a cam?

Kelford 264s aren't really 264s from what I've found, there actually bigger than hks 272 I believe, I wanted to buy a set of Juns but can't find a seller for them, but back to the point I'm looking at 272s for mid and top end I could care less about bottom end.

Well I believe if you look at anyone's setup making 500whp or more they are not going to be using a a 264 cam, I believe if you poke around here you'll find a link to where some evo guys dropped in a bunch of different cams and put them to the test, I think kelfords might have made the most peak...

yes you are correct ill more than likely run a 272 but I was playing around with the idea of kelfords, the adjustable cam gears also add alot of adjustability to whatever size I go with, just being careful and doing research so its one and done with my cams

You'll be able to hit your goal with the Keford 264's, kelford 264s have more duration at .05" hks 272 and Comp 101200's and plenty of people have made over 500whp with both of those cam profiles.

Food for thought, the Kelford 264's are 11mm intake and 10.5 exhaust. Compare those lifts with other cams and they are close to most 272's. I am running those cams and have seen 583hp in link with well over 400 ft/lbs torque. They pull to my redline of 8750 and I am happy with them. HKS 272's don't have as much lift. The Kelford 272's increase the exhaust lift to 11.00 I believe.

The Low Lift 272's, 272/278 or the 276/272's? The low lifts are a flat 10mm-I and 10mm-E. The 272/278 are 11mm-I and 11mm-E. The 276/272's are 12.50mm-I and 12mm-E. All three are excellent cams, low lifts are nice If your to lazy to swap out the stock valve springs. Either was Kelford Cams

Yes I am running Supertech springs, retainers and keepers and that helps me get to 8750 I'm sure! Good info.

More of a reference for him, I like the setup your running. Checked the profile earlier. I'd go with the 264's if i were him as well. Off topic 1990tsiawdtalon. Hows the midrange power with parts combo?

Boost starts to come in about 3700 and comes in hard, granted I am on a HX40. It is boostin hard at 5000. Midrange is good, low end lacks a bit but I am used to shifting around 4000 just because that's where the car likes it when I'm just out driving normal. I am also running on E-85. She's a real sleeper, that's for sure. I kept the stock rims on it just for that reason . I have a 2g head because that matched up with the EVO3 intake and I really like it.
