Project 'Wheezy' Coupe
Roy replied to Wheezy's topic in Members Cars, Project Overhauls & Restorations
What headgasket did you end up choosing? -
Ideally compression height and dome cc. My google search comes up with nothing reliable. Some RB30 pistons for twin cam conversions etc and the catalogue doesn't list that piston number. If my pistons are the same as the catalogue and the CH is 31.369mm vs the std RB25 piston having a CH of 31mm (0 deck same as RB26, 2mm stroke difference and JE state CH of 31...whilst some others like Wiseco and CP seem to be 31.5mm) If the std RB25 piston has a CH of 31mm then that is about right as it means the piston will be 0.369 above the deck. I measured 16thou/0.4mm so in the hunt. Trying to suss a head gasket for std squish or perhap tighter squish if there is a more optimal target

So anyone running old Arias RB25 pistons? I'm having trouble finding info on the pistons in my engine. They have 371521 engraved in them and sit proud of the deck by ( from memory) about 16thou

Yeh, but these are going to get destroyed so rather not sacrifice new ones. Looking for used ones

Looking for the drivers side bracket that the injector ballast resistor pack mounts too. Also after a couple of the std jacks. Interior door handles and surrounds

What pistons? If CP they appear to be about the same piston shape as mine. I've had to pull the engine out of my old bus so sifting through parts at the moment -

I want this car -
Love the car and build....one silly opinion though....is there a chance with the breather from the catch can to get oil condensing in the low end of the bend and hydraulic the breather system? I guess if the can is effecient enough than the line to the breather wont have enough oil to condense and drop ou

R32 GTR EFR 7670 Build
Roy replied to Dievos's topic in Members Cars, Project Overhauls & Restorations
Ah...just skimmed and saw E85 mentioned. Great result on 98. Seems nothing wrong with the internal gate setup! -
R32 GTR EFR 7670 Build
Roy replied to Dievos's topic in Members Cars, Project Overhauls & Restorations
So that means? Am I guessing right that 75% of the improvement is fuel as E85 masks the high back pressure and any inefficiency in the setup and just gets busy making numbers? Then may the tune with more accurate ignition? I know my old setup loved going to E85 as it simply allowed more boost and ignition everywhere over 98 when the thing just became too prone to detonation. E85 seems to make inefficient air pumps work a load better. Looks a far better result and imagine drives like a different beast -
Cheers, I may just rip mine off and do it over Xmas

Just sooo cool!

Are they all the same? Use the same pick ups etc? Got an R32 with RB20 and want to know if i can use an RB25DET sump from an R33 or R34 as i want to do a custom sump

A Boy's Love For His Rb20
Roy replied to Roy's topic in Members Cars, Project Overhauls & Restorations
So looking back a week later now I feel frustrated. The first and only lap was a rather leisurely lap and not bad at 2:42 all things considered. Wish I could have gotten another 3-5 laps as I think I would have gotten it down into the low 30s or high 20s rather quickly. After that its going to take a load of laps to get anywhere near the limit....but not even worried about that. Its definitely a place where you need to treat it like a tarmac rally and appreciate that a pinched brake may mean a horrible table top ride back to the pits Anyway...over the next few weekends will need to fix the stoooopid filler neck. Fuel tanks check/roll over valve and stupid radiator shroud that decided to crack and meet the viscous fan. Stooopid old cars and meatball flags! ? -

So 2 days at Bathurst didnt go to plan. Slapped enough stuff together to do only 1 lap. Fuel filler tank kept spewing fuel meaning meatball flags. Then had a few other small similar things go astray...and ultimately fixed a few things on the fly that called into question othet things that need a dyno run to work through so only did a lap at gate pressure Running twin GT2860-5s T -

So...this will keep me honest... Thanks always to Racepace for being able to make a bunch of mismatched parts cobbled together work so well
