Bigger cams porting the manifold adding a bigger spacer and a new header.

Hell yeah.
Ever thought about ITBS?
Engine is a monster.

vtecmaster85

Itbs would be a good idea as long as the sizing is correct for the setup.

I'm running a Skunk2 ultra race intake manifold now. 4.5 liter and the ultra 90mm tb. I'm going to stack a 2.0 spacer on it and make it a 6.5 liter. And we are cnc porting the manifold runners to match the head.

vtecmaster85

I say try the spacers first .

Where are the spacers for sale at btw?

43!

For the race manifold, ebay or site sponsors in the marketplace.

A forum member was making them for the street manifold but I can't remember who.

vtecmaster85

how has the bearing life been on the rotating assembly? my buddy and i where gone do the low bugget version b21 crank and rods and cp custom pistons for a 2.1 liter but was told its hard on the rod bearings. this is one of the nicest peace of work ive ever seen. so u did 310 with ur old head on the 17.5;1 2.3 bottom end then tagged the valve and put your new head on and made 332?? what fuel are u on now still e98?? also back in 2011 when u had the fuel problem which pump did u switch over too? aem ? aeromative?

I run a A1000 and VP M5 now. And not had any bearing issues as of yet. And my compression is down to 14
5.1 / 15.1 right now fixing to cut the new head to bump it back up.

B23-Vtec

I am in the process of trying to get a new header and some bigger cams now. Plus porting the manifold runners and making the plenum bigger as well. And will be flow benching the head to.

I noticed you were using the long rod with the 95mm stroke. Now that you're at 98mm, do you know what rod length you're using?

B23-Vtec

This one is stock rod length

Okay cool. Which rod though, LS or gsr length?
The reason I ask is, Im wanting to do a 98mm stroker and I already have LS length rods. If those will be okay Im going to do 98mm, otherwise Ill probably go 95mm with long rod. I just cant find any info on the rod length used on a 98mm stroke or if the LS length is okay or not. I know the 2 rods are only 1mm length difference, but I don't know how much of a difference that will make.
I do appreciate the help.

vtecmaster85

Type in the Big end width of the crank you're using in Google. That's what I did. From there search around

I don't know the big end width of that crank. I don't have it yet. Id be ordering the scat light weight 98mm crank. If you know it, please let me know and that will determine which rod will fit on it.

vtecmaster85

Oh and the big end bore of the rods for the crank too.

AllMtrRex

The rod journal diameter is the same as OEM B Series at 1.771in
Scat cranks are set up to run a LS/B20 rod with a big end width of of .935in

That is exactly what I needed. Thank you.

B23-Vtec

Scat cranks take ls rods

B23-Vtec

And the pistons have to be custom made for the setup. To make up the difference for the rod length and stroke.

Thank you. That is what I needed to know. I ended up going 95mm. Got a deal on a crank. Now Im just building the rest.
