So what head gaskets are you running and at what point does the standard head gasket create major issues,also is there any advanage in fitting oversize head bolts for a NA turboed motor runnin around 12-14 psi? i ask because my RB30E+T has decided to leak compression on 1 cylinder into the water jacket and split my radiator.

if your running a hi comp set up with 12-14 psi through it you should be running a cometic head gasket,around $350 but is a multilayer steel gasket and will lasy and save you alot of money in the long run,and you will also get sick of ripping the head off every couple of months.so its a goon investment.na you wont need "oversized" head bolts,your head shouldnt be lifting at 12-14 psi and if you want "bigger"and "better" head bolts,get a set of ARP head bolts ,also aroung a couple of hundred,you can get the cometic head gasket from sta parts and same as the arp bolts

awesome thats what i thought eh took my car for it first run last night wound it up to 13 psi went extreemly well no detonation or missing, but turns out it had a dodgy headgasket... are the arps actualy studs or still allen key bolts?

na they arnt a cap head(alen head)they are 12 point nuts,best way is to have a look on their site,that will give you a fair idea what they are like http://www.arp-bolts.com/ http://www.trademe.co.nz/Trade-Me-Mo...-378055799.htm (http://www.trademe.co.nz/Trade-Me-Motors/Car-parts-accessories/Performance/Core-engine/auction-378055799.htm)

sweet thanks for that. spose i need to get my block decked and head planed for a cometic,yay.That just killed my 200rwkw for under 2g goal haha.

lol yea man i would recomend that you do if you want to do it properly,otherwise chances are that it could blow agian,i know i dont have to tell you this because you are a mechanic but that will be the reason you headgasket has blowen,head may be warped,rb30s are knowen for it,someone could of got it hot before you.but take the head off and put a ruler on it and see if its warped and go from there.having a 200+ kw isnt as easy as it sounds.but should be doable for under $2000

thats includind buying the car! lol paid $400 for it not going due to the transistor and cas being full of water... turbo, manifold, injectors, ecu, wastegate, ect have only cost me around the $700-800 mark

Sweet sounds like you going to have a mean vl when finished even if it costs u 10g it'll b a killer Some original photos have not been recovered yet.

yeah... I was trying to keep the spending to a minimum as its not the tidyest vl around and apprentice wages are pretty **** as you can imagine...

true that long as body passes wof eg rust, interiors tidy it ok but the best thing would be seeing it go hard down lakeside or hood aerodrome doin some good 1/4 miles Some original photos have not been recovered yet.

No need for head studs.. probably no need for a mls gasket either.. fix the problem why it blew not just mask it... cars have run plenty more boost than that with a GOOD tune.. Make sure the deck is flat, and get the head faced and checked for any cracks... if you do go an mls gasket you dont need to deck the block you just have to be certain its flat and spotless..

yeh ive decided to just chuck a new head gasket and bolts at it... block surface is good heads good, has had recent head gasket so suspect the re-used head bolts have = fail

Use a genuine nissan gasket..

is there an actual difference between the na and turbo genuine gaskets? ---------- Post added 26-05-11 at 12:43 ---------- as my supplier lists the same gasket for na & turbo

same.. i didint mean turbo gasket.. just a OEM gasket not aftermarket..

i knew what you ment Some original photos have not been recovered yet.

re check the torque after a couple heat cycles as well
