Nice, what did you get exactly, what specs, and where from?

I am interested as I want to build up a RB25 head soon and I have been thinking of using Supertech

[AlpineFreak]

Using,

Tomei Procams 270/10.25mm

Solid lifter conversion

1mm Oversize intake/exhaust valves

Tomei valve guides

Double valve springs

Titanium retainers

Stem seals

Have a look around on the IPG-Supertech website. Very quick and very helpful..

Here is the link to the stuff I brought.http://www.ipg-supertech.com/cart.php?target=product&product_id=1301&category_id=853

I have been keeping an eye on the Supertech stuff from IPG on ebay. I too have also been thinking of going the solid lifter way also when I build, unsure if I should for my use.

[soturi]

ahhh...270s....its gonna sound fat >< wish i had the money to splash on cams

are you assembling yourself?

[AlpineFreak]

yeah hopefully should sound good.

Nah not assembling myself, I lack the skills. Going to employ a good friend to do the head work for me.

The way the dollar is at the moment, you'd be better off buying straight from IPG rather than ebay, imo.

Lol this thread starts off classic

[r33cruiser]

I will look forward to the rebuild thread when the 10.25mm cams snap a few springs

260, 9.25 would be better suited.

PS, what turbo?

Do rb heads take 1mm over sized valves??? Wether it be a 25 or 26?

[Beer Baron]

yeah just. well a 26 will but there are some considerations. like how much lift, duration etc as that affects how far out the valves go and the timing of their opening in relation to each other. the last thing you want is any valve on valve action. but yeah it should be ok.

I am doing oversized in RB25 head, so yes for RB25 det.

[ahh 33 s2]

1mm over in & ex with 270deg and 10.8mm lift going to pose problems
