Just looking at a mild set up (at least mild in my opinion).

B16B Pistons (.25 oversized)
Skunk2 valve train (springs, retainers, valves)
Portflow Bronze Valve Guides
Skunk2 Stage 1 Cams
Port and polish/5 angle valve job on the head

That's it internal wise, what do you guys think? Won't be anything too crazy but should good for the street imo. I'll also invest in a nicer header (opinions on that) and maybe a intake manifold.

 

What block and what head...

 

oops, forgot that

B18C1 block and head.

 

i'd say get a bigger cam. For the compression you will get with the PCT's in a B18C block (12.3:1ish) you would get a lot more out of a stage 2 or 3 cam.

 

CR will be closer to 13.4 actually.

Would Stage 2 cams pay off more?

 

If you call a 13.1+ compression motor "mild" then DAMN...hahahahaha. Anyways, when you're that high of compression your camshaft choices are pretty much endless. I would say it comes down to, after this point, how high you want to make your power. If you wanna rev way high, I would look into RM M22's, S2S3's OR the Pro 1's, or even the BC4's. I wouldn't reccommend the S2 valvetrain, I would opt for the RM gen <U>1</U> springs, they have more seat preasure than the gen 2's. I would personally do the M24X if I knew I could support them Header wise I would, if money wasn't an option, do the new DTR "b-unit." SMSP also bulds a great header, but I'm not too sure how you plan on running that much compression on pump gas, or are you??

BLOX IM for sure BTW

 

I figure with 94 octane I would run this on pump gas with damn good tuning.
Link ot the RM web site or any more info on them so I can look into their valve train?

I'm calling it mild cause there isn't really too much work done to the block besides pistons. 13.1+ compression is far from mild though heh.

As for the header I was looking at AN-R but I'll check out the 2 you metioned.

 

anyone?

 

head Gasket 2.8cc big vol= 488.3cc
piston dome vol. 6.3cc small vol= 39.2cc =12.45:1
camber vol. 44cc
deck height .25mm 1.3cc
cyl vol. 449.1cc

with b18c head it would be about .25 higher so 12.7:1

i run 81.5mm ctr's in my b18c on 91 =P

ah, well....that's the numbers I got from zealautowerks.com.

Thanks.

 

The main RM website.......http://www.m24x.com/


Also, check out this thread...especially Tbone's motor..has had MANY cams in it with HUGE lift and many many dyno pulls, the best valvetrain out there in my opinion

stage 2 cam for sure at least the stage1 will not get you the max. power w/ the set-up you are planning on running...

 

I would consider running the P73 pistons as opposed to the PCT's. You'll have reasonable enough compression that will work well with either a stage 1 or a stage 2, and if you want more compression, you can always later upgrade to high compression valves or a thinner headgasket.

 

Thanks again people

 

its better to start with more compression and use a thicker headgasket....cometic makes a .040 gasket that will lower compression .5 ....BUT the main reason for doing this is piston to valve clearance....you start running thinner headgaskets and shaving the head you run the risk of smashing a valve into your piston...i would rather run pct pistons with thicker headgasket then shave my head or run a thinner headgasket

plus pct's with cometic .040 headgasket will yeild 12.2:1 compression...great for stage2 cams and low enough to still run pump gas at full timing...plus the increased piston to valve clearance for safety

Thicker headgaskets also are prone to fatigue and blow out earlier than thinner ones (assuming the block and head were perfectly straight). Plus, there usually is enough clearance to raise the compression enough to dial in most setups. A buddy of mine installed JUN 3's with the intake cam advanced two teeth on the timing belt and the exhaust cam retarded one tooth on the timing belt in a GSR motor with PCT's and still didn't have issues.

It really all comes down to exactly how much compression you want. If you plan on going over 12:1, then PCT's would be the natural choice, but if you want to stay under 12:1, then the P73's give you plenty of flexibility.

 

since when...i know of plenty 600whp+ boosted honda's running cometic gaskets with no problem...if the gasket is installed correctly you will have no problems...copper spray is your friend

Amen to that.
