I have a 99 ls1 in my rx7 and Im getting some 243 casting ls6 heads for cheap and an ls6 intake. Im also porting the throttle body, maf sensor and buying a ported ls6 oil pump. Im thinking of getting the magic stick 3 or 4 cam package from TSP. All im looking for is 400 whp. and good driveability. This is my first ls1 build and I want to do it as right as possible and stay with in budget

Any recomendations would be awsome.

I made 404rw with a 224/228/114 on basically that set-up thru a Moser 12 bolt. Great driveability too.
The 404 was actually on the old heads, I have the LS6 heads now and it went 412/400 rw (still thru the Moser 12 bolt) and that was a hot humid day with under inflated tires.

I don't think you will get great driveability with a magic stick, but that is only my opionon. And also I would check and make sure that you won't have to fly cut with those heads and that cam. If I am not mistaken you might have too.

Im not sure if I have to fly cut. Ill have to find out. First Ill have to find out what Fly cutting is though. LOL. I know the magic stick dreability wont be great but you can get the magic stick 3 with 113 lsa so that could help it a little.

I just checked there web site and it said they installed the Magic stick 4 into a stock 2001 ls1 with no other changes. except ugrading springs, pushrods and retainers. And 2001 and up have the ls6 head right

You will find that a smaller cam will probably do more for you overall. But the larger cam will get you that all important dyno sheet.. Dont make the usuall mistake of going huge on cam.

dont get caught up in the hype... that light car and 400rwhp will be deadly... You dont need a MS3 or 4 to get you there... besides, power under the curve is where its at.

I'd go with something in the range of 228/232 .595/.608 111 for you... maybe even a 110.... off the shelf cams normally leave something on the table with a specfic setup... I'd rather talor make a cam to go with my tailor made setup.. JMO.

I Know the Dyno numbers arnt all that important. Ive been doing some reading and the MS4 dosent seem to really out shine the MS3 unless you have some really nice heads to match up with it. Ive also read some good things about the Torquer V3. It has similar number to what is suggested above at 231/234 .643"/.598" 111 LSA

2001 and up none came with LS6 Heads, some 01's came with a LS6 Intake, and most of 02's came with it.

Flycutting is were you notch your pistons for valve travel, I think if you run the 5.3 PRC heads with that cam, you will be fine if you let TSP know, so they can sink the valves in a bit. I know they do that for there customers. But that is with the stock combustion chamber.

Keep in mind fellas that "area under the curve" could be all for nothing in a 2600-2800 lb car with deep gearing. Better to make it up top and utilize the gearing than to make too much down low and spin.

turbo_d16

so what do you suggest angelR. I see you have a trex and Ive thought of that too but thought it would be to much cam for Drifting.

What have you drifted with in the past? How do you want your powerband or engine to feel? I'll say that even with my cam and lack of supporting mods my ls1 will make most of the darling powerplants of the dirft scene seem anemic anywhere before 4k.... I sold a gt2871r powered s13 coupe to build this rx7. You'll have over 300 rwtq just about anywhere from 3k on up with almost any selection. You just need to decide the feel you want imho, my car as it sits pulls hard to 7k, I feel that compliments the character of a ricer mobile better Don't want to leave all of that unused tach

what are the rear gears in that? i think i herd 4.10 or higher. i would get a bigger cam the "lack of low end" shouldent be felt with 4.10s and a light car, if i had a 2700 lb car and 4.10+ gears i would look in the the vindactior

Agree with above, its all about the combo, not JUST the cam. I am looking a going with the 228/232 and this is the biggest I'd go. This is both Patrick G's and Predators touque cam while still making a bunch up top too. With that light *** car and some low gears you wouldn't feel the dog out of a larger cam like a full wieght F-body would with stock gears, etc.

PREDATOR-Z

You do not need a drag cam to make it a top end performer. You can do that while remaining civilized, with better all around performance as well.

You guys got to get out that bigger is better box

turbo_d16

Right now Ive only drifted my Rx7 with the CAI and exhaust LS1 in it. Im kinda leaning toward the torquer V3 or the MS4 and there is this other cam that PREDATOR-Z called the Raptor that sounds nice. Im not sure who makes it or where I can buy it though.

Call Comp... they can custom grind anything you want... on the lobes of your choice

turbo_d16

I would have no idea what to even ask for

I agree he doesn't "need" a drag cam, but he does have the luxury of choice with very little chance of creating a 3800 lb gutless wonder.

Your suggestion as always is a sound one. Consider also that with one of the torquier cams you can keep the revs down a bit and maybe keep the bottom end alive longer..... plenty of dead bearings from drifted lsx's out there.

research is your best friend its pretty simple... just do some reading on lobe designs and profiles... thats where people normally end up leaving a lot of power on the tabel when designing a cam... they have sevral different profiles.
