Camshafts or Meth Injection?

[imagine3163]

Hey guys, as Christmas comes around the corner (I have to look ahead to something) I was thinking about what I should do next on my car. I am currently debating between two things for my next upgrade and I was wondering what you guys think would be more beneficial. The first is a set of BC 272 camshafts. The second is the Devil's Own Progressive meth injection kit. They are both around the same price so I really don't know which one I should get next...any opinions and why?

I think cams would be the next logical step to help your 3052 make some decent power. Then if you want to run higher boost later on get the meth kit. The 3052 is a great pump gas turbo. Just my opinion.

I totally second this. I have a friend who has the same turbo on his 1G. Cams will be a better upgrade at the stage your at.

Cams and/or SMIM

Great, it sounds like the opinions are pretty unanimous. Looks like I'll be getting some nice new camshafts for X-mas!

Cams and adjustable cam gears...

 

[assault187]

Cams would deffinatly compliment the turbo...Hopefully you dont have to big of a knock issue with the boost your running, otherwise I would say get the meth.

In order... Cams, Meth, SMIM, More boost!

By the way, that meth kit is pricey if its about the same price as the cams... I use the CoolingMist methanol injection kit $222.00 shipped off of coolingmist.com and it works great!

Cams and adjustable cam gears...

Are cam gears really a necessity or worth the expense with the BC camshafts or are the stockers fine? I would rather not spend another 350-400 on some cam gears that won't really benefit me without some SERIOUS dialing in and dyno time.

With BC cams, adjustable cam gears is a must if you really want them to perform like they are supposed to.

Granted each motor is different but I found my BC cams perform best at 0° intake and -5° exhaust.

 

[dsmmike50t]

I'm with everyone else get the cams first and then get the meth kit when you want to run over 25psi on pump. Cam gears aren't a necessity at this point. Do you have dsmlink or least a 1g cas in your 7 bolt?

There's a local guy running the 3065 with bc 272 cams and he runs consistent low 11's at 132mph.

+1 ^

I say get the cams, but it doesnt mean they will offer more power than getting the meth setup.

Its possible that if you get large enough meth nozzles and a proper setup that you can add enough boost and timing to make more power than just cams by thereself will give you. Id only expect a 30-40whp gain up top from the cams, not to mention the lose of low and mid range torque you may loose from getting the bc272s.
( Maybe thats just a sympthom of not having cam gears to properly degree them.)

Depending what your current pump gas tuning limits are, its possible that using meth you could be adding a additional 5-6 psi ( w/ your turbo at least), plus timing,
which in my opinion will make the car faster than just adding the cams will, of course assuming if you arent already bottle necked on air flow somewhere .
Or even if you were bottled necked on airflow and barely increased your boost, the more aggressive timign increases and leaner AFR's will still give really nice power gains.

Just throwing that out there for you to consider in case more power is what you are looking for, but personally, despite everything I just said, Id get the cams if it were me, as im not a big fan of meth injection.
I have those BC272 cams by the way, except on a 16g setup so my results may not be the same as yours....

just my opinion, but you would save some time just getting HKS... they're pretty much dialed in... and there's nothing wrong with used cams, especially HKS
Again that's just my opinion, but I thought it might give you some ideas

It's a shame that no other company has out-done HKS quality for 4G63's ... (AFAIK)
I remember working on German cars where Schrick cams were the absolute best... then came along Kent, which were better cams at a lower price

FP cam grinds > HKS

 

[daren_p]

What amount of boost are you currently running & what amount of boost do you want to run? Depending on this, the meth kit may be the better choice. If you have abit extra cash, I'd probably recommend FP cams. They run around the $430 mark last time I checked but haven't heard people having issues with them performing great when installed straight up (ie no cam gears), though I have heard people having issues with the BC's. So if you have to add adjustable cam gears with the BC cams, they'll run you more then just the FP cams. Just something to consider.....

 

[imagine3163]

What amount of boost are you currently running & what amount of boost do you want to run?

Im currently running 20 psi. I would like to run more down the road (27-30), but I'm thinking I am going to build up the motor before I run more than 20lbs...thats why I like the idea of cams. This motor has to last me at least another year before I can rebuild it. The FPs do sound more appealing than the BCs if I will have to get cam gears. What about the DKS2's? If they are as similar to the HKS cams as they say then that would be a great way to go for only $350.

 

[andy4g63]

Like everyone stated before me, cams should be first. It is pretty obvious, cause with bigger cams, the motor will breath better in upper RPM's and you need that, before you increase boost with the help of METH, not the other way around. If you have money get JUN cams, otherwise HKS and call it a day.

 

[Blindsey]

I am running DKS 272s and I love them. I did see a little loss on the bottom end but my top end is wicked....

Not to hijack but would it be safe to rev up to 7-8k with stock springs and retainers with like some fp2's or hks 272

 

[Freerevving]

Yes... although they are less than (only) 5 pounds weaker than your average aftermarket spring, they are VERY DURABLE... I've heard too many horror stories about aftermarket springs... so I just shimmed some OEM springs 0.060"... which is only really necessary with 280's, but I did it anyway.


Hey I almost forgot about FP's! which are really Comp Cams... great cams from what I know about them, although I've only used HKS's on a 4g63... From their reputation, I would rate them 2nd to HKS on a street car... I might pick them first for a car that doesn't cruise through traffic, or for a car that I want to play with cam timing

 

[Black_Bullet]

Well I have bc272s with stock valve train, and I set my rev limiter to 8k and Ive bounced off of that rev limiter several times. Hell I recall hitting 8500rpm back when I had stock cams. The stock valve train is not bad.

 

[daren_p]

Normally my vote, like all the others in this thread would be cams first but I have to say I've seen some extremely impressive results with meth injection & stock cams, which may sway my vote depending on the users perticular goals. Now with that said, for your perticular case if you only plan on running that low of boost & not really pushing the turbo, cams would get my vote.

On a side note a good condition "stock" motor will handle a good amount more then 20psi & not have a problem. If you don't already have them, a set of ARP headstuds is good insurance but I have been running over 20psi the last couple years on my stock bottom end without any issues. I currently run 24-25psi daily on my 3052 & have run to the 30psi range at the track (all on pump gas with meth injection). You will really like that 3052 once you get in the 25-30 psi range

 

[PIMking]

I have the comp cam 100-200's and adjustable gears but I havent had the car to a dyno yet. I am going to get meth injection also. Cams first!

To answer you question. You can always run race gas, so meth is just not my cup of tea. Cams and port-match a 1g intake manifold on there would answer your question. To be honest with you. If your mod list is current, get bigger injecter and run more boost. You'll be just faster on race gas running 25-30 psi of boost, then 20 psi and cams in your current setup. I and many have done 30+ psi on stock shortblocks. It's not the safest way to do it, but nothing useally is when you're pusing the limit.
