Head & Cam options for 2.3 Stroker

[96GSXDave]

Here is my current setup to help you guys give me proper input.

1996 Eclipse GSX

I Will be using a 1G Head.
I have a 1990 block 2.3 Stroker with Eagle H beam rods and Wiseco 1400HD pistons 8.5:1.
ARP head studs and main studs
FIC 1050cc Fuel Injectors
Walbro 255 Fuel Pump
JMF Race Intake Manifold
FP HTA Green Turbo (Internally Gated)
Tial Q BOV
SBR FMIC (Short Route)
FP Exhaust Manifold
3" GM MAF
2.5" Full exhaust (no cat)
Tuning with ECM Link V3

Built Trans from Jacks with all the Evo 3 gears. Including taller 1st and 5th.
Welded center diff.

(Thats the important stuff. Hopefully i didnt forget anything)


Here is where my problem starts.
Im not sure what to put into the head or which cams to use to go best with my setup. I will NOT be reving past 7,500RPM Looking for strong low and midrange power.
Car is not a daily driver but street driven often.

bc are not the worst cams for these cars . there one of the best. theres tons of members on here that have switch from hks to bc and picked up hp and torque.

 

[NOSLO2PT0]

HAHA Please show me those people. There are TONS of examples on here where BC cams were the WORST of the bunch in test results.

 

[ed1380]

The fp2x are just based off the hks 272's with a little more topend. That's why I'm going with hks 272 regrinds.

I had bc280's. Didn't even take them out of the box. Just sold them

 

[NOSLO2PT0]

russell3123: This is for you. This is the AMS cam test from a few years ago. It's for the EVO, but it's still a 4G63 platform, and the cams that were tested will have very similar comparative results in a DSM. Look at all the diff. manufacturers that were tested, and tell me exactly where did Brian Crower cams end up? Take your time, might have to read it a few times. All the results are on page 1, btw.

 

[russell3123]

wheres the link?? I just went back and reread the thread , and the guy switch from hks 272s to bc 280 and pick up hp. So, my bad about the false information its been awhile since i read that thread.heres a link to a good cam thread http://www.dsmtuners.com/forums/cyl...est-delta-hks-272-delta-k272-bc-272-cams.html

Here is a link to the results of the AMS cam test.

And of course you gain power going from 272 to 280 cams. But you will loose bottom end.

 

[NOSLO2PT0]

Ah, my bad! Somehow the link didn't come thru. Thx SOAD for posting it.

 

[kidtsi]

of course you will pick more top end with bigger cams. duh!!! BC cams are crap though, you have to timed them with ajustable cam gears in most cases.

CRAP,CRAP,CRAP.

 

[russell3123]

Wouldnt cams flow different in a evo then a dsm engine. I read somewhere the bc 280 have a similar lift to hks 272s and the bc 272s are similar to the hks 264

would never guess crane cams would be that good

I run FP3x cams in my 6-bolt 2.3 stroker. These cams do require Supertech Dual springs and retainers. The cams can no longer be bought new, but I got mine used with about 1000 miles on them for like $300 shipped. You can find them if you look. They idle almost like stock, not much lope to them at all. But they're amazing cams. When I build my next stroker I will most definitely buy another set. I'm using my factory 6 bolt head with some SS 1mm O/S valves, those really don't make any difference though. But as said before strokers like a big cam, I would go no less than 272s if you're looking for a cam that was meant for a 2.0. I would look more at 280's. But the FP3x cams were designed specifically for stroker motors. That's why I went with them.

Looking at the graphs , the hks 272s and the bc stage 3s are very similar. They also have similar specs. So why are bcs crap?

 

[Boostnvegas]

I personally prefer bc 272's

If you read the text with the dyno graphs the biggest downfall of the BC cams is that both cams needed to be dialed in with adjustable cam gears because they weren't ground properly. Once set up right they work alright but properly degreeing in cams is a real pain in the butt especially with an engine in the car. I would guess that most DSM owners don't even have the proper equipment to do it.

 

[96GSXDave]

Has anyone done a cam test on a dyno with a DSM?

 

[NOSLO2PT0]

Has anyone done a cam test on a dyno with a DSM?

Yes. Reread this thread.

 

[SOADweskey]

AMS did a test on a DSM back in the day, it didn't include as many cams though and did include some that no one really uses anymore. Most notably there is no Kelford, FP, or GSC cams.

Here is the link AMS Infamous DSM Camshaft test | HKS | Crower| Jun | Web | Eagle Talon | 4g63 Cams

i also have a set of fp3x cams, i couldnt rave on them anough, i found them no comparason to hks 272 the low down tourqe is huge, driveabilty is awesome,

im running 404kw atw on 21 psi (2.3 gt4088r)

with one large power band, weve revd up to 8500 on the dyno and the power hadent fallen off at that rpm

its a shame they dont make them but however if you could find a set you wont be disapointed

 

[96GSXDave]

I'd love to find some FP3's.

Since I can't I'm looking at either the FP4R's or Kelford 280's

 

[ed1380]

I've heard that they still have the fp3's. You just need to call them to order

 

[talonDSMerr]

Isn't the FP3 cam profile the same as the Comp 101300?

 

[96GSXDave]

Ok I've decided to go with the Kelford 280's

They do require duel valve springs correct?

Which springs and retainers should I go with?

 

[SOADweskey]

I have never looked to much into the Kelford cams. If this is the correct cam, 1-TX280 Camshaft Set then they say bee-hive springs are required.

If that is the case you wouldn't have a problem with the Kiggly Racing Springs.

 

[96GSXDave]

This is off the STM website....

KIGGLY BEEHIVE SPRINGS & RETAINERS
With a stress optimized coil cross-section and surge reducing variable pitch, these springs are the best money can buy for a 4G63. Kit includes titanum retainers and steel seats. 325lb/in and 97lb installed at 1.440", these springs support 0.500" lift. Fits 90-99 DSM and Evo VIII-IX.
Price: $399.00

These?

Anywhere with a better deal?

 

[ckrell]

Thats about the best deal I've seen. Can't wait to see how your setup dynos out at with the 280Ks.
