Hi guys! I want add some fat camshaft on my base 2011(manual,44k miles) keep stock rpm range, use for drag and drift
pls guys be patient and pay attention to links
What I need for right this? there are goes the list:
1) camshaft(TSP stage2 or BTR stage3, both of them are 3-bolt pattern, thats require additional buy conversation kit from single to 3-bolt?)
2) pushrods 7400(why some pushrods cost 50, another 120? Is difference worth the money?
3) lifters (another lifters, again is difference worth the money?)
4) high volume oil pump (I not sure if its need my ls3 have 22psi oil pressure on idle with 225F oil temperature, mobil 5-30)
5) Rod Bearings Set
6) dual springs set (another set, twice price)
7) a lot of gaskets
8) bolts vs studs
BONUS:
Do I need bolts for roker arm?
Do I need roker arm upgrade? (as far as I know ls3`roker are good and don’t have any problems)
Do I need this guy?

 

1) both good choices, should make plenty of usable N/A power... 3 bolt conversion is a no brainer while your there and a far superior setup
2) Pushrods should be the last thing you do and you need to measure for them... your lifter choice and preload amount will all determine that.
3) If your in there yes... you 100% should do lifters but not either of the ones you listed.
A) the lifters you listed on ebay have no real quality control to make sure their authentic GM lifters
B) even real GM lifters are problem prone... spend the money in the right place and get a set of Johnson link bar style lifters and ditch the trays... you wont regret it but you might with factory lifters (ask me how i know)
4) Never hurts, may as well while your there
5) ??? why are you messing with rod bearings while your doing a cam swap? Leave the bottom end alone unless you already have a problem
6) the second ones if either but buy them direct from the vendor so you know your not getting rebranded crap. Always buy this stuff direct from vendors, to many fraudulent companies out there and its not worth it to save a few bucks when it might cost you 10s of thousands if you dont get lucky. Ether BTR, PAC or TSP .660 lift springs will be fine.
7) Buy your gasket kit from BTR or TSP when you order the cam... again dont trust ebay vendors to be providing OEM parts and you want OEM gaskets to save yourself headache. Remember head gasket size is crucial. BTR or TSP will put you on the right path.
8) are you boosting it? if not a bolt will do just fine, Studs never hurt but they arent needed on a cam only n/a build... again buy direct from one of the vendors, lotta fakes out there.
Bonus 1) no stock is fine.
Bonus 2) trunion upgrades are a good security while your there, vendor direct here too, plus im pretty sure for an extra 100 bucks you can buy preassembled trunion upgraded rockers from BTR and not have to go through the setup hassle yourself.
Bonus 3) not if your going to a 3 bolt setup.

One thing I'll add, while your there ditch the ls3 timing guide and do an ls2 style dogbone: https://www.summitracing.com/parts/n...iABEgLiUPD_BwE

Your on the right track just dont cheap out on the small stuff, in the end it will cost you far more than ittl save you in the short term. I can't stress enough how important it is to buy direct from the vendors. Ebay is full of so much fraudulent chinese knock off crap that you just dont know what your gonna get. I would figure out if your going BTR or TSP and stick with them on everything. Both are great to work with and will know exactly what you'll need for your goals. Call them, both have awesome technical support folks that can get you pointed in the right direction.

 

thank you very much, you answered all my questions and doubts. also I think too about ls2 style dogbone, it requires replace timing chain, right?

 

@StayinStock can I ask you once more? Are My ls3 have low oil pressure? 22psi oil pressure on idle with 225F oil temperature, mobil 5-30

 

that seems pretty normal... i wouldnt sweat it
