I know thats why i bought a degreeing kit.

When i checked my v2v with the rockers vs pro3's, the rocker setup had tons of room anywhere except for max adv intake and max ret exh. The pro3's on other hand needs 5 degrees of seperation to feel pretty safe but 6 would ease my mind even more. I was very surprised but so glad i checked.

Well a little update!!!

I picked up a rlz CNc ported head with super tech oversize intake valve it's 1mm over and stock size exh valve. It's a p72 casting so it should bump up my compression a little bit.

Still debating on sticking with the 52mm twm's and building a box of some sort or going with the 3.5liter skunk2 ultra and the 90mm tb.

Going with the pro 3's too until I get some roller cams made.

Any opinions or suggestions.

I say the single lobe cams with roller bearing rockers, the big plenum intake manifold over the TWM, maybe evne a 95mm t/b with a large spacer (it adds velocity and makes more power - not a myth), feed the intake manifold from the front of the car (bumper)...before K-series I had mounted my radiator off to the left side of car to make room for a big velocity stack at the bumper, then you install a heat restictor between the radiator and the intake pipe....use 3" intake pipe and a large 5" velocity stack.

in for updates on this build. I believe the 52mm itbs are too small for your your 86mm bore. You would need at least 54mm+. Keep us updated!

Chugger

If i can find a decent deal on a 95mm crank i might pick that up and get a set of high comp pistons. With my setup now and the gsr head im looking at closer to the 12.6-12.9 comp range which i really want a little more but i really dont want to shave the head to get it.

I will prob end up selling the itb's to fund the other manifold and tb.

Also if i stay 92stroke there is a good chance nitrous with get thrown into the mix.

Is there any other manifold recomendations?

We have a simmaler build.i am running pro 3s and 86x92.i didn't read through the whole thread and I kinda skipped some stuff but have you thought about upping the compression ratio and switching to e85 if its locally available?i am running 55mm kinslers.if you stay the manifold route i would look into that skunk 2 and 90mm tb setup as mentioned.have you also thought about the golden eagle manifold?

Chugger

I'm on e85 now as I have a pump somewhat local.
I'd love to have kinslers but don't have the budget for them.
I thought about the ge manifold but have heard mixed reviews about a sheet metal manifold in n/a applications.
Any thoughts on plenum volume 3.5, 4.5, 5.5 liter?
I believe the ge is 6 or more liters.

I went to a AFI custom intake manifold.. I think that alone would be the next step.

A roller setup would be nice, but believe it or not, you're not going to MAX out the use of a 3 lobe design.. I got guys making 1200+whp still on 3 lobes.

A roller has a lot of advantages specially in the weight area, but for the price of rocker arms + cams, you'd be better off going with a custom 3 lobe design..

me personally? I'd run a 2 lobe setup before a roller setup, that's just me..

Chugger

Intake manifold is def next on list just still up in the air on which one to get and tb size?

I really like the roller the car just acts completely diff with the roller setup and when I say diff I mean in a good way.

Why do you prefer the twin lobe setup?

DDTECH

Price for 1..
Most roller rocker arms are more pricey now...

I sell vtec killers + rocker arms at a combo price...most companies can't do that, or even afford to do that.

They both are lighter, and provide less rotating mass which in turns makes high high rpms easier on the motors..


Roller cams will require more seat pressure then vtec killers.
The rollers feel different to you because they always will offer Faster ramps and faster closing, catch 22 though, because of the seat pressure..

Chugger

Well I have decided on the skunk2 ultra with 90mm tb combo. Going to try and order tomorrow.

Anyone have input on plenum size 3.5, 4.5, 5.5?

Pretty sure the 3.5 is the general consensus on n/a applications but would like to hear input.

DDTECH

The 3.5 should be more then enough, a 4.5 would be pushing it but I would recommend that for something like a 2.2+liter..

That should easily do well, the tapper runners are a thing of awesomness.

whitesihatch

in for updates when u receive the manifold.

koczeka

I hope U will achieve great results with RLZ, I am not convinced about his CNC head potentials in N/A application.

Chugger

The rlz should be fine, i wanted a p72 casting and the deal i got on the head i couldnt pass it up. This head made great power on its previous n/a setup.

The intake manifold and tb are on the way should be here today or monday.
Ive got an aem rail just need a fpr now and figure out what throttle cable is needed with the ultra.

Need to get a headgasket and a few other odds and ends aswell.

Chugger

Some parts showed up!


Something else i grabbed

Chugger

I still need a fuel press reg not sure if i want a universal one or rail mount yet.

I have an anodized black aem rail but really want to check the skunk2 conposite out.

Also trying to get an idea of throttle cable and bracketry i believe the simplest way would be to use a gsr bracket the bolts directly to the tb and get the supporting cable.

I broke my tranny at the track the other night so ive gotta fix that aswell.

slowsleeper

whats with the stuff on the Skunk IM??

Chugger

That im not sure of it was on it when it showed up.
Casting release agent not sure?

Im going to try some aluma brite to get it cleaned up

Glad to see your taking those ITBS off. Those TMW's are not what you call a (power making choice) in my book, but looks like your moving in a better direction with the Pro3's and the new intake manifold . Clean out the inside cast finish with a nice polish and see what it does this time around!...Also ever thought of trying a different header? like a 4-1 megaphone race header? There is so many good ones out there now a days

Chugger

Bringing my thread back to life with some updates.

Motor is out of the car going bigger

I grabbed a 95mm stroker crank to replace the 92mm crank
doing a longer rod setup to keep the rod to stroke close to what it was.
im taking the carrillo pro a's out which are 5.394(stock ls length) and replacing them with a set of 5.531 eagle hbeams with the 5/16 625 bolts. this eagle rod is relatively light not as light as the carrillo but alot stronger for what i plan on throwing at this motor which will be nitrous and a good bit of it.

I picked up a big valve rlz cnc ported head in a p72 casting, skunk2 ultra 5.5 liter but might add a 1 liter spacer to it still debating. Fluidampr race pulley not sure if its going to work in the crx or not but will see.

Still running the smsp header but weighing my options depends on whats in my budget.

I ordered custom pistons from arias with a raised pin height for the rods and added stroke. I am going with 15.5 comp which is high but didnt want to question myself about wanting or needing more comp I can always put a thicker hg to drap it down a shade. I got the upgraded pins to handle the nitrous load. I know what your thinking thats a alot of comp on spray but will work as I will be off pump e85 and go to atleast C85 or possibly q16 just depends. I like the ethanols because it will keep the cyl temps cooler which will help with the high comp and nitrous but will see how it pans out.

I will be taking the older roller cams out as I got a bigger set they are alot bigger. I plan to dyno the pro 3's and the bigger rollers the same day and go from there. The cam that does the best will get used and nitrous will then be added. I am going to check v2v and p2v of each while the motor is out and also degree both before hand so it will make the dyno day go faster.

I also picked up an meziere electric water pump to add to the mix.

I am going with a direct port dry nitrous setup using a nos pro race solenoid and an nx maximizer to make it progressive and change the ramp rates.

putting a walbro 400 intank pump in and also using an 044 inline to keep pressure high and to keep it from dropping.

I plan on ducting an air intake scoop/ ram air into the front intercooler opening on my jojo front end and moving my skunk2 alpha half size rad infront of the engine instead of trans.

Wish me luck pistons should be here in a week then will get the p2w wall done ring end gaps main rod and thrust clearence.

DDTECH

Awesome, glad you didn't give up.

Chugger

Didnt give up just changed up.
I hope my nitrous setup will work out for me its treated you well derek.

DDTECH

LOL I lub my nitrous.. gonna put more on it here soon!

Mach1n1st

Good show sire ill see you at the track
