The B20VTEC discussion thread

[tinkerbell]

and what head/grinding bit did u use with it?

i used the 1/2in and 1/4in sanding drums with the 60 & 120 grit rolls.



then 400 and 800 wet/dry to smooth it out by hand...

[Lerlo]

wat?

you wann run SK2 Pro cam's with stock B20B pistons?

i doubt that 'combination' will be any good...

Whys that?

[TODA AU]

great info thanks.
don't suppose you know what's required for skunk2 pro1 cams in a b16with stock valves? would that require going too deep adrian?

Do the flycuts as described...
Then assemble the motor, set the cam timing & check PV clearence with clay or platicine.
Only increase the depth if you're touching or have less than 1mm clearence.
Re cams...
Lift isn't so much of an issue as duration

[tinkerbell]

Whys that?

compression ratio might no be high enough...

happy to be corrected though

I just got myself a b20 block and an engine stand.
My engine stand mounting points are 70mm long.
The Engine block has 4 threaded (10 x 1.25) holes I presume
And 3 through holes.

Which holes should I be using to mount the engine?

Sorry its 4 threaded 12 x 1.25 holes

It doesn't matter, just use common sense and hold the engine securely.

The through hole can be used no dramas.

Cool, thanks.

Anyone knows where I could get long 12x1.25 bolts.
Tried 2 bunnings, repco and supercheap, couldnt find any that were long enough

Check yellow pages for a fastener shop in your area

[Chr1s]

Supercheap and repco are useless. I can't beleive they are associated with that name considering what they sell, especially supercheap.

If you're in Sydney, southern area, hit up Industrial Fasteners.
