ADM,

Are you the bloke that Andrew is doing a price up on?

The RB25 head has hydraulic followers so from what I've been told everything is fine with the 2 oil feeds. Only time you are required to block on off is with the GTR head which is solid.

The SOHC has a few draw backs.

1. Fuel efficiency.

2. Lack of rev's.

3. It does make less power for the same setup of boost etc.

4. requires less static comp ratio as the sohc head is more common to detonation

5. requires more boost to be run to make the same power.

6. they seem to bit a little more peaky with narrower power band (lack of rev's)

+ to go the SOHC head I would have to change ecu etc as it isn't a straight bolt in.

I guess its like saying why go a RB30DET when a worked 5.7ltr will make the same power. :)

Im BAAACCCKK!!

PC shat it, so i let dialup expire, but im back now with BROADBAND!!!

Details of car to come with list of items for sale.

    • I can see between the water jacket and cyl 3 there wasn't a hard line of combustion gas. It certainly appears that the issue is coming from there. Yes, checked the tension. All at 100ft lbs where I set them 5 years ago. These blocks can crack but generally when they have been over bored. Mine is only 0.5mm oversize at 89.5mm. They break between cylinders around the 91mm mark. No sign of that with mine. My gut feeling is the head gasket lifted a while back when the studs stretched and i bandaided it by retorquing the studs. It's finally let go.
    • My Nismo 1.5 churps a bit on reverse turns when cold, but besides that feels like a stock diff.
    • Yes, but, I paid cash and I'm pretty sure the receipt was in the bin 10 minutes after I got home Note to self, keep all receipts
    • Bunnings would have just handed you your money back on that one!
    • So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel
