The time has come to rebuild.

I currently am trying to gather data on what i will need to support the stupid amounts of boost i want to put thru the new motor.

i currently have r34n1's - gt2860-?? but they have been high flowed to accommodate a 5mm larger front wheel so are a bit larger than normal spec.

i want to pump atleast 2bar thru them, currently they were pumping about 1.4-1.5bar

what bottom end am i going to need to cop the abuse? this rebuild will probably take up most of this year. and will be doing as much myself as i can.

and other parts required for rebuild purposes?

i'd probably want to spend around 8k on the motor..

cheers

Is it a stock motor currently?

from what i know, 33n1 pistons, n1 oil pump, cams and the rest is a bit unknown untill i pull it down.

i'd probably want to go with another oil pump to jun etc. and hope that there are baffles etc in the motor already.

i'm thinking of doing rods, pistons, oil pump, head and might modifiy the sump at my friends work to hold some moar oil.

Well ive just been down that path so lets see, maybe these numbers can help you out?!

Pistons (CP) $1200

Rods (if you go eagle and stay 2.6L) $700

Jun pump $1300 from CRD or $200 less if you know the right person

Baffles - depends on what you get. The trust sump extension is a good price for what you get, $450 delivered (nengun)

Head - $1500

It ads up fast doesnt it

Yeah there seems to be atleast 5k on just parts. cheers for that i better start saving for it!

i dont have to worry about anything else but the engine, the rest of the car is fairly sorted which i'm happy with its current setup.

      RB26 block, rb26 head

      Block bump. $400. As above cyl 6 needs bore or sleeve.

      I would think making the argument that the travel is limited by a spring flexing against a spring perch as "the same method". Later on in the document they do state that the spring can't bind on full bump travel and cannot come loose in full rebound travel as well. (which is all very sensible). The laws are actually pretty sensible and reasonable. It's just that the people who enforce and check them don't actually read them or know them accurately. "Oh, coilovers? Instant fail mate. Don't even need to look at it." - Guy who will be instantly reported by me. There is probably merit to people who do get defected for height also get defected for the suspension in that state that allows it. I did never consider the people who are complaining about coilovers being picked on are also running around at 50mm off the floor.

      Ethanol Content Sensor - Always at 11%?

      I think given SAU's knowledge of E85 we can strongly conclude that 10% ethanol in almost any situation is entirely fine. Almost all of the myths against E85 were overblown, let alone E10.

      From your link See bold text, is this referring to damper settings, if so that may a issue for "some" inspectors, I cannot see aftermarket coilovers having the evidence that "must be available that its functional performance is equivalent to the original" Maybe just remove the adjustment knows and hope for the best???? Meh 5.2 Suspension travel In all instances, modifications to a vehicle’s suspension must ensure the integrity of the system and not compromise the ride quality. At least two thirds of the original suspension travel should be maintained in both directions (rebound (i.e. extension) and bump (i.e. compression)), and rebound must be limited by the same method used by the vehicle manufacturer or if this is not practicable due to the nature of the modification, an equivalent method. If an alternative method is used, evidence must be available that its functional performance is equivalent to the original.

      They actually don't - They adhere to VSB14 rules just like Victoria. The rules are against CABIN adjustable height, and it quite clearly states that the height has to be within parameters. I asked the VASS engineer to confirm this when I got my car engineered and they refused to engineer the coilovers because they didn't meet the requirements for requiring engineering. (mine are height adjustable.) People "Not wanting to bother" with "Actually reading/knowing/adhering to the rules" should result in fines and immediately losing the ability to issue blue slips and/or RWC's in Vic.
