I've been kicking around the idea of taking the built LS head off my motor and going with a vtec head so that I can have some street-ability back. I like the rediculous low end torque, but feel that i can sacrifice it for a more sound setup.

All the bottom end has is CTR .010" over pistons on stock ls rods/crank. I'm looking for something cheap of course, but with the best mid i can get. Topend isn't a concern since the bottom end wont spin it.

Just scratchin my head...

 

what exactly are you asking? what cams to get?

 

I suggest you replace the rod bolts with arp rod bolts and spin that puppy to stock vtec redline anyway... Use a vtec head with m22's or the like, you wont be let down

 

If you arn't looking for a top end shift why both swapping even ?

He stated he didn't want to spin more rpms or gain extra top end, so I'm asking why swap out to a different head..

His post is a jumble but it sounds he's quite happy with his setup.

 

im lost!

 

wow, ya i re-read that and im even confused...

My LS head = crower 404's, springs/retainers, skunk2 pro cam gears, ITB's, RC370cc, cheapo header.

Its basicly an autox motor. I just put a cometic headgasket on it to take it from 13.1 to 12.2 cr. It lost some of its umph and its just not as fun.


I know a vtec head will ultimately flow much better, even if i hard limit the motor at 7800rpm.

I'm looking for an all around setup that has good street mannors with the best bottom end feel.

That would include cams, TB/intake mani or another set of ITB's, springs/retainers or not (I assume not), rough cam gear setting and maybe a better header.

Everywhere I read, people are looking for big top end power. I would rather have an average peak, but with the flattest curve. How can this be done?

 

what are the specs on the crower 404's

from crower.com:::

intake / exhaust
adv dur: 276 / 272

dur @ .050": 226 / 224

lift: 445 / 434

 

i wouldnt mess with those crowers, junk!! i would stick with like skunks, buddys, toda b's you want too pay for quality you dont want junk. im just lookin out.

 

Why are they junk?, and sk2 buddys and toda don't make LS cams, crower are like the best NA LS cams you can get.

JRSC would be a great start

 

As far as NA cams go, there isn't much other choice. they have good profiles and have been around for ever. If 2 or 3 stories of how they failed scare some people, then thats fine for them to stay away. I'll run what profiles I like till they fail and then join the mob!

I'm not a big fan of JRSC's. First, I have too much compression to start bolting a blower onto the thing. Plus, I'd turbo all day long before i'd SC... this is an NA motor.

 

you might dabble with the Rocket non-vtec cams, the L21s. 262 degress@10.2mm on intake and exhaust side. just my .02

If your set on a VTEC head, I am prone to the PR3. Tends to flow better than the P72 head. There is a reason why it is used on both Type R motors.

if by better you mean nearly the same, yes.

 

the only reason i'd grab a pr3 is b/c they are cheap.


I'll have to sell my current head setup now to fund the vtec head swap. I bet thats going to be tough to sell...

to be honest...the vtec head and stock/type-r cams might make more hp than your current set up
just get a vtec head and aftermarket valve springs+retainers from a good company like super tech etc
then you can run whatever cams you chose. i would pick pro 1's if your staying
around a stockish 7800 rpms or bc+3 etc.

 

who makes pro 1's? i at least know the other ones are buddy clubs...

 

skunk 2

 

big lobe specs?


I've also been told that just a stock head could probably make the same, probably more power than the ls head setup on it now.... which makes me sad, i put all that time and money into the valvetrain and making the ITB's.

 

nothing is better than experience

 

experience no doubt... hence picking honda-tech's brain

 

i would say that you change pistions to

ctrs are kinda high cr for street but you probly needed them with the ls head

edit:
what was whp of the ls head setup and got any pics of the home made itbs
