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

      Turn signal wiring question

      By OakvilleGTR · Posted

      Good morning all, Bit of a random question but figured I’d finally throw it out after wondering for a long while. Before I start, I'm hoping to do this purely out of personal preference. I think it would look better at night, and don't mind at all spending a few hours and dollars to get it done. I've copied this from a non-Skyline specific forum, so I apologize for the explanation of our headlight switch setup that we all know. Here we go: Zero lights (switch off) Parking lights (switch position 1) being a rectangular marker on the outside of the housing, my low beam being the projector in the centre (position 2), and a high beam triggered by my turn signal stalk. Most North American cars I’ve owned of this era have power to the amber corner (turning indicator) light as part of the first switch (parking lights). I’d love to have these amber corners receive power when the headlights and parking lights are on (headlight switch), yet still blink when using the turn signal which is of course a separate switch. Hopefully I’ve explained my question correctly. Is anyone aware of a way in which I might be able to achieve this? Thanks in advance

      Mistakes were made, my R34 Story

      My heads are cathedral port! It's likely possible, but I don't want to add any extra moving parts (I know they don't move) between the heads, manifolds, etc. It will also affect how injectors/fuel rails etc sit and I don't really know if it would change how the FAST manifold goes/sits/fits. I have the LS6 steam pipes already as I have a very late LS1 block so it should be fine. I couldn't find anyone who had ever actually used one for this purpose, it seems 100% of people grind the water pump. The thermal spacers are 12mm and are half way to the cost of the newer water pump anyhow... so if it comes to that I suppose I'd rather buy a new pump. The bearing in the pump I do have is a little.. clunky, but it hasn't done that much time and I never noticed it when the car was together in the past few years, so..

      Lower A arm Skyline v35

      By sonicii · Posted

      The bushing has failed, not all that uncommon for a car of this age.  Any mechanic should be able to push in a new bushing for you, or you can probably buy the entire lower control arm, complete with bushes.

      Could you not use "thermal" spacers to give the clearance, like the ones I used between the blower and head? That raised the manifold height by around 10-15mm Albeit the ones I used were for cathedral ports, but I assume they have similar for rectangular ports????

      Looking for autoelectrician in Perth who can do the OEM to double din stereo upgrade.

      Thanks Paul I reached out to Autotainment but they no longer work on JDM cars as the guy who used to do the work moved on and is no longer doing that kind of work. I am talking with Level Up Audio though.
