Im starting my 2.3 N/A build and i dont know what cams to use. I was going to use the W41 cams but was wondering if there were any better cams i could use. I also would like to know what crank would be best to use, maybe a 2.4 crank? im going to be running a ported 995 head w/ 086 valves with 11.1 compression pistons.
My goal is to get over 250hp at the wheels.
If you would like to see my full list ill post it

Oldsmobile Rocketparts used to offer a "W41 Hot Grind" set of cams, but I can't remember the specs for the life of me, as I haven't owned a Quad for 4 years now. There are PDF copies of the Rocketparts catalog floating around, which you may be able to nab for the specs. Also *shudder* Mantapart */shudder* used to offer cam blanks for custom grinds, meaning someone at some point produced them.

250whp is a high goal..achievable?perhaps .. but i know only 1 person that did it , Karo. i dont think ive seen a 2.3 get that high all motor..if your thinking about using the 2.4 crank you might want to wait till i get the stroker dynoed just so you can see what numbers it makes...200 whp is probably a more realistic goal and is quite easy to do with a 2.3 but if you want 250 at the wheels be ready to boost of spend LOTS of money .......
and yes there are larger cams...try to find a set of w41 hot grind cams
Hot Grind 2's are about the most radical lift you will get using the stock 086 valve springs, before you need to start worrying about valve float.

"Youth in Asia"...I don't see anything wrong with that.
a couple of people on quad4forums say that have reached 250hp at the wheels n/a.
whats it take to make 200hp at the wheels? if i can get that information i can build off of that.

The way to get to 250 whp.......
High Compression via head or pistons
Ported EVERYTHING
SS Valves
Decent Cams
Upgraged valvtrain, springs, lifter, etc.
Lightened flywheel, clutch
Lightened Crank Pulley
Removed Balance Shafts
Oil Pump Swap
Intake, 2.5" mandrel exhaust, header
Port Matched HO manifold w/ 58mm TB
Ignition of some kind?
8000 RPM Tuned Via HPT or equivalent tuner.
That is it in a nutshell. When building an N/A monster, you are going for ultimate efficiency. You wan't the lightest everything, and the best cam you can find because it is the heart of your power. The parts I just listed are worth thousands of dollars in price and labor to have machine work done etc. It may be a little cheaper if you can find some good deals but the bottom line is you are going to end up with a very expensive motor with not THAT much power, it won't be very street driveable due to the lightened everything and lopey cam.
i think your confused with the 2.4..cus the 2.3 doesnt have balance shafts..nor does it need an oil pump swap and the ho manifold comes with it...
Oh, my bad. Oh well, the principles are still the same.

Actually IIRC the '95 2.3L Quad 4 does have balance shafts - the only year of the Quad 4 to actually have them.
Comp cams still sell the hot grind 2 and 1 cams. They can make you any size of cam you want. The HG1 are .410" and 226* while the HG2 are .430" and 222-224. Mine are .430 and 224*. If you go with anything bigger than Ho cams, be ready to have a rough idle and maybe stall at the light if the compression is not high enough. HP tuner won't be enough for a 2.3 built with HG1 or HG2 cams.
With any cams bigger than Ho cams, you will need to have the idle at 2500 anytime you are on the clutch over 5mph. otherwise say goodbye to brakes. You'll end like the flintstones.
I don't want to go on and on about what you need to do. First you need to learn how those engine works and understand them really good. Then you can start thinking about what you want to do then I can help you.
Otherwise if you go by what people tell you and buy this and that, you will end up with ALOT of problems. Trust me on that.

2.3 Ho
Also I forgot, getting W41's and bigger mean no low end. It's nice for city driving when you don't want to race all the time. My HG2 with 12:1 compression don't kick before 4500rpm. And I mean kick. Before that even at WOT it's like part throttle.

i like the 3000rpm kick in, how can i keep it like that but still make power? or somewere close to it

lol i dont think you can say it any easier than that
hahaha I think this thread is just itching for a repost of something SpeedRacerZ put together in response to a thread regarding cams on Feb 14th 2005.

hahaha yeah, I was doing some searching around earlier for the JBP cams, where to get them, how much they were, etc.. and I found that thread with your excellent pearl of information on the cams, and was going to re-post it then I noticed that you wrote it, and you were active in this thread. I was like 'w00t'!
On an unrelated note I have now pieced together that 'JBP' is an acronym for JBodyPerformance.. Which is seemingly uneventful, but for me it's all about the small victories, and the ability to be easily amused by the simplest of things.
BTW, I have added your "Valentines Day Got-No-Girlfriend Cam Information" to the
086 Swap - Questions.. thread for redundancy, and general information regarding the cam options available for the swap.

The Mantapart sport, competition and racing cams are for the 2.3, not the 2.4.
The sport cams are the W41 Hot grind 2

2.3 Ho
Comp still makes custom 2.3L cams... any lift, any duration, for the older 2.3L (pre95) so the power steering is the old style still. I'm working on a way to make the cams to the newer power steering pump, I'm still in the R&D phase of it.
Get the 2.4L crank, and stroke that puppy. Easier to find pistons and rods (all 2.4L stuff, just get the pistons made custom bore).
A 2.3L hearder is out there, but it still doesn't fit the 3rd gen j's yet.
get a chop saw..... cut the end off the LG0 intake cam..... mod you lifter barrels to fit the larger lifters.... use a HO exhaust cam housing... use HPT to kill you CPS...... drill the HO cam for the HEX... (must be around 3\16 or so for a sweet fit to hold)
install it..... i know Brian is going to come on and clearafi it for me...
(im at work now.... Dealership!)

I copied the specs for them from their "2.4TC Quad Engine Racing Engine Componants" link....... but yea, they are technicly 2.3 cams (which are not all that hard to modify for 2.4 use)
