Ok so here goes, I am currently building an LS/VTEC for my EJ. B18A1 block with JDM B16A head. I will be running the stock B16 cams for a while until I build the bottom end. I have heard nothing but good things about OMNI power valvetrain components. Also Crower makes a nice setup as well and has been around for who knows how long really. So I can get OMNI or Crower valves, titanium retainers and dual valve springs for nearly the same price. Based on quality, performance and reliability which brand would you choose and why? The plan is to eventually run a nice Garret ball bearing turbo pushing big psi. But until I have the *** load of money required to do this, the bottom end will be all OEM components.. Your input is appreciated. If there is some other company your absolutely head over heals about and they have all valvetrain components mentioned let me know. I'm certainly open, all I want is the best for my girl Desiree..

 

I havent heard anything about the OMNI valvetrain til recently and no back up graphs or anything. But if there the same as the skunk2's (which they could very well be but a little stronger) then there more for a street set up.

If your going to go with a strong aggressive cam then i would go with the crower valvetrain. It all really depends on what cam your going to go with.

 

I was going to go with something like the Skunk stg 2 or something rather agressive like that..

 

Installed Omni's in my friends car with BC Spec IV cams and it rips all the way to 9200 RPM's with no problem

 

Whats the price difference?
Personally, Im looking at crower (Omni doesnt make b18b parts...)

 

i'd get either omni or rm valvetrain

**** this better not end up a draw, LOL.. Anyone else here have any experience, opinions?

 

Honestly, I'd try posting this is All Motor or FI. You'd get more detailed, experienced answers overall.

 

Thanks litter box, good call. I will just shoot a link up in those forums since I hate double postin..

 

you can ask for it to be moved too

 

Nah I'll just leave it here. Oh snap, the tie has finally been broken.

 

Omniman the way to go for all-motor...you have to see dyno charts at his websites...

 

I've never worked with Omnipower or Crower.. But I have worked with Ferrea and Portflow and both are great..

 

Ive used crower in my NA ls/vtec and reved to 9k and never had a problem

 

Crower has been around longer than any two of us combined. I have more faith in their valvetrain components than any other brand on the open market.

However.

If you contact Rocket on this board, owner/operator of EF1.com, he can probably outdo the Crower and Omni stuff without breaking a sweat or the bank. I've used his stuff before and it's Goddamned bulletproof. Ti retainers and springs and such. Real R&D intensive parts.

Rocket &gt; Crower &gt; Omni.

When I noticed the Crower setup was actually a few bucks less I thought nothing but longstanding quality. That is all I'm looking for. I have also heard great things about Rocket as well. Makes the final decision so hard.

 

Just a goodnight bump to hopefully get some opinions of the late nighters..

I'm with Archi on this one, Crower over Omni. Nothing against Omni but Crower is a big name and been around for quite a while


Archidictus are you talking about Rocket Motorsports? There site is http://www.m24x.com Ef1.com is fitness club btw.

(the few) serious Honda tuners here in Greece swear by Rocket Motorsports! I can personally vouch for their clutch

I have been strongly considering a Rocket cam when I finalize the head setup.

Rocket, OMNI and Crower are right in the same price range which is nice. They are all quality parts, and nothing on the net notes and cons to any of them (obviously a site isn't going to talk **** about what they are trying to sell you.) and the tuners have had nothing bad to say about all 3 in anything I have seen. Each brand has its own set of pro's the other brands may or may not have. It seems like it really comes down to preference on this tip. I'm sure the decision will be somewhat impulsive but at the same time not in vain.

its for a b16 head not a b18b head.

personally i'd go with crower just/c of their name. omni has a good name but not that of crowers. also I would go with crower b/c omni only makes valves for a d serres, and thats what i am building.

Slightly off the main subject at hand but somewhat involved with it as well. So before I put anything together I will obviusly have the head decked to make sure there isn't any warpage. The local machine shop I'm working with is very good so I was thinking about having the head milled. But I'm walking in the dark on this subject. I wouldn't want to do anything I'm not 100% sure of since we are dealing with interference engines. Anyone have experience or know someone who has had experience with this. Or even if you have seen anything online shoot it my way..

 

Well just dropped the head off at the machine shop. I'm not having it milled down at this point. Haven't been able to gather any solid info on it at this point. Don't need this build blowing up on me. But I'm still interested in how far you can go with these things. First LS/VTEC build is exciting..

 

So I'm not one to embark on a project without doing my research. So I have found about 5 LS/VTEC how-to's around the net. For the most part they are all very similiar. This one, I would say maybe 3rd best overall, said you can't use the PR4 LS pistons because they don't allow for enough valve clearance for the VTEC valves. He says the B16A P30 pistons will work if you don't run forged. This guy also mentions the ITR/GSR oil pump which we have discovered are the same part number as the LS. You can see this write-up at the link below:
http:/www.hondaswap.com/forums...33559

The write-up done by Sport Compact Car doesn't mention anything about the pistons.

http://www.sportcompactcarweb....ybrid

I know you should definitely get a VTEC water pump and you MUST run a GSR timing belt. The B16 block is about 8mm shorter than the B18 and the LS water pump has 3 less teeth than the GSR (19/22).


Has anyone that has built an LS/VTEC here run the LS pistons? Have any problems? Crower makes oversized valves I was considering. They are 1mm larger on intake side and .5mm larger on exhaust side. Does anyone here feel this would cause any issues? Again thanks alot guys.
