Hey all, my rb20 poped a cooler pipe on a spireted run, so I fixed it up and now im noticing a boost differenc from gear to gear of between 1/2 to a full bar. That just seems to be a bit much. Its stock except int/exh, ball and spring mbc (set to 8 bar, witch was consistant in all gears before the pipe) any info will be appreciated. Cheers.

Fair enough I would have thought being near stock boost it would hold a consistant amount, cheers for the replys guys.

Also what would be the highest acceptable boost drop with a mbc? As my drop is up to 3psi as ive worked it out to.

ok so i found that the boost gauge line was leaking, fixed that but in the process i found that with a boost leak test (http://www.supramania.com/forums/showthread.php?19718-DIY-Boost-Leak-Tester) that air was leaking from the dip stick, but i have no other symptoms of dodgy rings or anything. any insight would be awesome. cheers.

    • 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
