My Engine Rebuild So Far

[JE-R33GTS-T]

Pity, while you were waiting i was waiting for an r33 crank from Tasmania.

Classic lol

Here are some Pics off the new and machined pieces

Oh and the DEAD PISTONS

[Harey]

Nice pics! Any reason for the drop in compression ratio? I would have tried to increase it (~9.5) unless your planning a big boost setup.

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.

[JE-R33GTS-T]

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?

[DR 32R]

Nice build, hope it continues to go well. i think you'll end up with a much more boost proof result than the much vaunted forum stocker.

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?

[JE-R33GTS-T]

Getting my stock cams refinished/ground this week $290 for the pair.

A 2.6 is really 2.57, 1mm o/s takes it to 2.63, 2mm o/s takes it to 2.69.

New Pics

Currently awaiting initial start up on Monday :-)

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!

[JE-R33GTS-T]

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
