Would the Rocket L21 cams be good for a turbo ls setup?

 

you are better off spending money on a real head.

Right so since i'm not looking for a 9sec drag car. Does anyone else no if these cams will work well on a turbo setup. And apparently I already have a real head, i'm just wondering what to do with the fake one.

What kind of power are you trying to make ?
Stock ls cams work well & they are almost free

Not really sure about any of the setup yet. I was mainly just wondering if these were turbo cams or not. I have run ls cams on a turbo setup already so I know how they feel, I was really just wondering if anyone had used or know anything about the L21 cams.

 

Well, my brother has a built B16 bottom with a GSR Head using the M21 cams and 750cc Injectors put down 415whp and 246ft/lbs of torque on 16lbs of boost @ 8900rpm.



Another friend with a built B18C bottom and a GSR Head using the M21 cams using DSM 450cc injectors put down 314whp and 202ft/lbs of torque on 12+ lbs of boost @ 9000rpm. This car could have made more power but ran out of injector so Howard tuned it for 282 (see dotted lines) on 11.5 lbs of boost.



Both cars were tune by Howard at RLZ Engineering. If the L21 is anything like the M21, it will make more power on less boost.

crower 404's or 403's with cam gears to help dial out excessive overlap if it becomes a problem.

 

Crower 404's FTW. V-tec is nice but a LS is such a sleeper cause everyone never thinks anything abt them. plus wo can argue with torque

You just suggested that a B18B turbo is a "sleeper" and you spelled VTEC incorrectly. You officially made my "never listen to this kid's advice" list. 'Gratz

Anyone who thinks any turbo B-series motor is a sleeper needs to get their head examined.

well idk how they are where your from but here where i live at an LS motor isn't fast and can't be fast. but i guess its just cause everyone i into VTEC. and no i never suggested anything i just stated my opinion but i guess next time i see you post in the same topic i do i'll just either put (fact) or (opinion) at the end of every sentence so it can make your life easier

I have some advice for you... find a large rock far far away... and crawl under it.

the amount of money you would spend on getting the cams and valvetrain could get you a gsr or b16/pr3 head

with the vtec head you have oem reliability thats cheaper, wish i would have done that when i built my first ls

 

lol at newbs


Anyways, I would suggest the crowers honestly, but if your buying cams you need to get the appropreate springs and retainers too.

The LS cams would be the best bet, because you really do not need to upgrade them for a little bit... you said you arent going for power, maybe consider a slight regrind on LS cams to give it a little more effitency in boost; you will like the top end.

The LS bottom end is pretty strong, if tuned properly it should work out for you.

If you are going to shoot for some high numbers (you stated not to) then you would consider prting the head.

Pardon my misspells, if any because I am without my glasses!

Right i've been down that road already and i'm not crazy about interbreeding motors. I already have had a turbo LS and with the stock cams the power seemed to die down in the top end, I was planning on throwing some better springs and retainers in but I was looking for a good set of cams, i've considered the crowers, just came upon these and was wondering if anyone has used them.

 

Like I stated in my previous post, if they are anything like the M21 cams for DOHC VTEC applications, they will make more power or less pounds of boost. If you need a price on them let me know. I sell the VTEC M21 and M22 for $850 and that price include springs and retainers. If you want me to get a price on these, let me know.

 

They will work fine. If you want more info, contact one of the dealers on here. Users Aquafina and clean rice are just two examples.

 

i can vouch for both those dealers also nice gents

 

i talked my friend into getting some BC stage 2 turbo cams with there valve springs/retainers. idk how they will work but i've read good things about them.
his car will be running soon, he is jst waiting on me to put his tranny together.


btw, VTECH is overrated.

 

I just gave up on this thread all together. No one ever really answered my question and all I got was a bunch of people telling me to get a vtec head, use the stock cams, and a bunch of other crap. All I wanted to know was if the L21 was a turbo or n/a cam and if it was a turbo cam how it performs.

I already know that the m cams work well, not like that's really pertinent at all to my question.

 

You had a bunch of people with zero experience telling you to run a VTEC head or use stock LS failure cams when pursuing power, because they think it's funny to dog LS heads for some reason. I wouldn't give up on this thread, I'd just ignore them.

403, 404, both work awesome and create huge gobs of midrange along with top end power. Yes, this was not your question, but the lesson here is moving away from the stock stranglecams if you are looking for more than 275-300 whp is an AWESOME idea.

I don't know particulars about the RM LS cams, but I had some decent luck with their M20/M21 combo on a B-VTEC, and Rocket was always good with the tech, so I'd be inclined to give them a try. Also, rodchesterricer worked hand in hand with Rocket... he told you what you needed to know, and directed you to two individuals who can help you out with specific knowledge and experience with the L21s.

I have seen good results in the crowers I was just thinking of trying something else, and I've hit that wall with the stock cams before which is why I was looking for something better.

That's what i've heard also, I guess i'll look into talking to them and see what they have to say, appreciate the intellectual input.

 

The RM ls cams will work fine. Also Webcam makes great turbo cams. Good luck

 

Yeah, I have some Web cams in my LS. Good stuff there, too.
