So I reckon I have just about finished modding this car now.

Bought it about 3 months ago changed all the fluids, did timing belt, serviced auto trans ect. Replaced sparks and then coils with splitfires as stock ones were mis-firing. That got it running normal. Then did a full 3" exhaust, FMIC, bumped the boost up to 11psi. Bought a SAFC NEO and had it tuned the other day. First few runs it wouldn't do over 148rwkw, then tuner realised fuel pump was stuffed. Put in a high flow pump and tuned the NEO and it pulled 199.3rwkw. Car is much nicer to drive now, pulls very hard throughout the rev range - my Apexi RSM is showing a 1 second improvement in 80-120km/h roll on after tune and it is now 0.8secs faster to 100 than before tune. Hoping to get down to WSID on Wednesday night next week to see what it does down the strip.

When I first bought this car I didnt want any mods, but then one thing leads to another.....ect

Anyway car is a daily so dont want to do any other power mods - as far as reliabilty goes is there any other supporting mods I'm missing? - I want this to last me a while.

That's a pretty good tune with the NEO considering it doesn't have much to play with in regards to timing.

My advice would be to get a transmission oil temp gauge, as a rule of thumb I have to wait until the Engine oil is 90c before I know I can give the car heaps without the auto slipping.

A temp gauge on the gearbox would let me know when the time is right, quicker :stupid:

Trans and dff should be OK at that power level without crazy abuse (shoving in D from N) and that sort of stuff. I've had 2 auto R34's over the past 6 years and neither showed signs of gearbox trauma...even the N/A that was boosted.

wow impressive tune,

how much did the safc neo set ya back (( that is the computer that was tuned right0?

Yeah NEO (piggyback air/fuel controller) was tuned only. PM sent on price i paid.

Have noticed quite low oil pressure the last week at idle - I started a different thread on it, really hoping its not something serious...

Why is your tyre presure 50?

Secondly how do you rate Race solutions to tune a skyline as we know they specialise in rotaries.

No idea on the tyre pressure, Hitman did the tune - I went with him after recommendations from others on this forum. Dyno figures can say whatever, but the RSM dosnt lie (relativley speaking in terms of improvements in times) so I'd rate him very highly.

      WGNC34 Rear springs

      By zoomzoom · Posted

      I've noticed my rear springs sag a bit compared to the fronts. I have stock springs and KYB struts. The front wheels are pretty consistent in their ride height, but compared to the front wheels, one of the rears sits 20mm lower, and the other 40mm lower. This negatively affects the ground clearance, and also angles the headlights up. What are some some economical options for new springs? Or information like good spring rates, lengths  in order to find a suitable replacement etc Far from lowering the car, I'd prefer to raise it a bit to keep it ground clearance friendly.

      I searched for ages as well, I'm importing an engine to get the head off it.

      Is there a good place to learn how an engine works online?

      By Duncan · Posted

      Save the youtube time, I can explain in a couple of sentences:   Internal Combustion Engines run on smoke which is factory installed. If at any time the smoke escapes (generally via the exhaust), the engine will stop running.

      RB26dett R33 gtst swap

      By Duncan · Posted

      That specific R33 GTST issue I ran across was putting a PowerFC into a series 2; it required a fuse added into an existing but unused circuit to fire up the PFC. That won't be the issue here as I assume the ECU powered up (OP surely would have mentioned if they couldn't connect). As Matt said, Haltech do have specific information about wiring in the Platinum Pro where there are minor differences across the 2 row plug models (R32/R33 from memory). Quick Start guide at this link: https://www.haltech.com/product/ht-055101-platinum-pro-plug-in-ecu/# At a quick glance, it is more likely to be a local wiring issue than ECU wiring (eg that connector near the left headlight might have differences) Start with the age old question....are you getting fuel and spark, at the right time

      New lightweight, square wheel/tyre combo for the E90

      Stay away from Enkeis for track use, they crack, just ask the Evo kids. I'd take Murray's advice and put the widest forged wheels in the right offset under them I could find
