Spool Imports Rebuild Kit supplied Ross Pistons 8.5:1 1mm oversize which was available instock the other was the CP in 8.5:1 but they didnt have the 1mm oversize instock. I wanted 9.0:1 but cost factors and the excellent deal Spool did me was to hard to pass up. My machinist and engine build have managed to get it back to between 9.1-9.2:1 by decking the head and block surface. Its a streeter and I didnt want to run 20+psi on the way to work or home at night lol tired I still think I might get a bigger turbo and run some big numbers later but as a daily street car 280kw with positive boost at 3000 was my aim.

Sounds great dude, 9.1-9.2 is awesome! Get a HKS 2835 Pro S for those goals in my opinion. Joeyjoey off this forum will most likely be selling a complete kit soon.

sure is a f**kload of money for street car

I am assuming the engine was stuffed and so he was forced to rebuild. Whats the difference in price to a standard rebuild? 3k? I have seen people spend an extra 3k in worse ways for a street car. Now he has a solid engine that he can lean on later on.

Yeah it spun a big end bearing and lost oil pressure as you can see the rings were shagged.

Price difference was exactly that $4000 more total to do things right first time.

Head had 3 bent valves 2 exhaust and 1 inlet I believe so they were replaced along with uprated springs. Machinist called it a overhaul and refresh described as "what should be done" by my builder not a no expense spared porting they flow well from the factory just time spent making sure it's as good as it can be.

the new GTX3071 would go alright?

Still yet to be proven. Either way it will be less responsive than a HKS 2835 Pro S but will make more peak power. 2835 Pro S is proven to make 280rwkw so thats why I thought it would meet the thread owners requirements.

GT30R Front with a gt28r core and avo turboworld custom rear housing purchased off a friend. His Stagea made 277kw ATW on 18psi stock 2.5 NEO with almost stock throttle response so will be very interested as is my friend with the result on essentially a 2.7

On that am I right to think it is close to a 2.7 as it is a 2.6 with a 1 mm oversize bore and 1.2 hgasket?

There's a billet gear N1 pump, for sale on the forums. Seeing you have spun a bearing, any oil system/control mods planned?I'm running a nismo pump, oil restrictors and bigger sump on my 25/26.

I have a N1 Nissan Genuine Pump now and restrictor in the galleries to the head so considering the primary usage of the motor to be street so sustained High rpm will not be a REALISTIC option. (Training to be a cop so High Range Speed Fine and HOONING would not look good). Running ACL Race Bearings so with good maintenence I am imagining it will be fine.

If I go drag racing or circuit I am going to run an oil cooler and a litre extra oil as safety because that is how the guys on here tend to manage it. I have oil pressure and temp gauges now too!

Also I have removed the standard clutch fan and radiator so now running twin 12 inch thermo fan and alloy radiator with the switching control of the fans. I could not believe how quick the car built revs after the change .... must of had a considerable load on the old wore out clutch fan

      Skyline’s charcoal canister !

      By joshuaho96 · Posted

      https://sci-hub.se/https://doi.org/10.4271/2005-01-3825 Heat causes positive pressure in the tank, a slight vacuum in the tank is normally caused by evap purge during normal driving. If the tank is cooled it can also cause a vacuum that pulls air into the system. The linked paper is quite interesting to learn the state of the art for evap fuel control, modern systems the tank is 100% sealed and the tank is reinforced to handle higher than normal pressure/vacuum. It only opens the vent/charcoal canister when you press the button to open the refuel door or when the engine is running. After some reading of systems like the W220 S-Class there's a check valve on the tank vent, but the primary reason it's there is because otherwise the intake manifold would be pulling vacuum on the tank: https://w220.wiki/EVAP_system   There might be limited vacuum relief via the charcoal canister, but I don't know how sensitive the check valve is.

      Anyone know this frontpipe?

      By GTSBoy · Posted

      But there's the archetype for the name plate! Here's my view on that stupid TÜV ruleset. Buy a brand name aftermarket piece of equipment. In this case, the Mines front pipe we're talking about. Get it TÜV certified on the car. Damage the underside of it, say on a speed bump. Cut out the damaged section, replace with fresh metal. (For the sake of the argument only), continue doing that to the whole pipe until it is all gone, replaced with new metal. Is this grandfather's axe still the same front pipe? The design hasn't changed (much). The pipe walls are in the same places. The flanges are in the same places. It is functionally identical. How does this differ from a pipe that is ever so slightly different in fabrication (ie the number of welds in it, a few mm here and there in terms of where the pipes run, are joined, etc)? Anyone with 0.5% of a brain can see that there is absolutely no way that the performance (power, environmental aspects, noise, etc etc) of it can be any different than the genuine Mines pipe. Maybe even Mines made 2 versions of this design, with the same differences. How would anyone (say a TÜV inspector) ever be able to differentiate between them? And yet, they are so bloody anally retentive about this stuff. Mad. How upset would they be if you had the wrong spring washers on the flanges?
