Unfortunately my headgasket started leaking about 3-4months ago, was making 302-308 rwkwk on 19lb on 98. Fixed it in a couple of weekends, Put new nissan headgasket and head bolts. Aiming for 340rwkw and up on e85 :) Anyways here's how it looked when i cracked open the head!

With that cylinder pressure I would be swapping out the factory head bolts for some ARP 625+. Your call at the end of the day... Perhaps you enjoy changing head gaskets. :P

Doing jobs like that is my occupation. If she shits a gasket ill put a mls gasket and uprated head bolts or arp studs

Are you another Kiwi? We only have E85 at two pumps in NZ that I am aware of. There are guys who bring in Sucrogen E85 (works out as like $3 a litre) and we've used this on flex fuel cars: http://www.trademe.co.nz/home-living/cleaning-bins/other/auction-634702052.htm

I've got a spare motor, things never break when you've got a spare :D

E85 is still hard work in NZ

Looks like i gotta put a spare short motor aside and wind the boost up. Test your theory

Yeah, still only the two pumps. Taupiri Auto Store have drums of Gull E85 which works out around $3 a litre too, may end up having to go that way

    • 49719 is the cooler loop. Right at the front, LHS of that diagram. Return line from rack (LP side) goes to cooler loop on RHS front of car, then back under engine and returns to bottom of tank. 49717M is feed from tank to pump. HP line out of pump is thick rubber, followed by the hard line that runs down to crossmember and runs in parallel (but opposite flow direction) to the LP return line. Nothing goes anywhere near the firewall or interior of car. The closest they get to that is the connections on the rack.
    • Thanks, plan is to drain all fluid tomorrow and do smoke test to find out the leak.   Appreciate your help and want to understand how the system work. So cooling is achieved by the long loop not any rad? The diagram seems to suggest it connects to somewhere inside the cabin and I thought that is a cooler inside firewall. If you look at the diagram it seems to show it connects to something inside firewall. I tried chasing it but not easy unless I take loads off   i am confident pump is good as fluid goes in and it gets soft( steering) but as soon as I turn engine off , loads of bubble come to surface and overflow. When engine is on , fluid level is below minimum but when off it shoots off and thinking it is sucking air in. I suspect aluminium pipe may have a crack line or whole   smoke test with no fluid should be a good start and if needed will remove the pump   In addition, the one going under the engine bay is high pressure line and one directly connecting from pump to resorvoir is return/ low pressure?   finally I searched and suggestion is to use dexron 2 but that is discontinued so bought dexron 3 as all research suggest it is compatible and shouldn’t cause any issues/ blow seals. I bought two liter of dexron 3 motul atf
    • Don't worry about. Just don't try to drive hard enough to make boost and you'll be fine.
    • Yes. This has already been said. It is a loop of hardline in front of the radiator. Because.... the pump is on the LHS and the steering rack hydraulic connections are where they always are on a RHD steering rack....on the RHS. The high pressure line goes down under the engine, along the crossmember, like it does on all Skylines. Don't just throw expensive braided hoses/other kits at it. Work out what is wrong and fix that.
    • Still got the afm on the intake, clamps are shut tight, only loose hose is the one that goes from the j pipe towards the IACV, since it's next to impossible to find a factory hose and the barbs are different sizes (I'm still using clamps on this hose to try and help it seal on the iacv side) I've ordered parts to make up the hotside of the intercooler pipes, I'll plumb it in and see what happens in a few days I suppose The turbo's internally gated, can I just unscrew the tension rod to let the gate open?
