Hey Guys

After a Metal Re-Inforced Intake gasket that sits between to two intake manifold pieces (not to the engine) for an RB25DET.

This attached photo should clear things up.

I'm currently running a standard rubber one and my tuner believes it is leaking under full boost causing a richness and major loss of power up high. He is unable to find a part number for the metal re-inforced version though, only the rubber one...

I find it hard to believe this is the problem unless the seal is actually damaged. All the same as far as I'm aware there aren't any aftermarket item available.

There is DEFINETLY 2 versions of the gasket as I saw both today (the reinforced one was unfortunately on another customers car so I could 'borrow' it)...

and also:

there are 2 types of gaskets.. there is one that is completly rubber and one that has metal inside so when you replace it get the one with metal inside so this wont happen again. Common problem.

The seal has not be 100% confirmed, but he has stated that it'd be worth the change since it looks like it is being pushed out.

It would explain the lean on vacuum and heavy richness on boost...

I've found this post that has an e-bay link in it to a collector gasket, but it doesn't really look too right...

    • 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
