Last friday I installed a Gates Racing timing belt, new idler& tensioner pulleys (and idler pulley bolt), aswel as a new Tomei adjustable exhaust cam gear (now set at 4degrees retarded).

Had the car re-tuned today to suit the new adjustment. Last dyno run made 248kw

now makes 260kw :D im stoked with the result! power comes on earlier, smother, and with a touch less boost (17 psi rather than 18). All my runs are on BP ultimate 98 octain fuel.

theres a few pics below of the belt, cam gear & dyno sheet.

for those who dont know...the cars basics: Stock engine

pod filter

FMIC

AVO hi-flow turbo

big injectors

big fuel pump

adj fuel reg

tuneable ecu

turbo back 80mm zaust & hiflow cat

do you find it a big boggy now that youve taken off the factory VTC solenoid ?

VTC is still there (just not in the photo). Its more resposive than its ever been now

Just a few questions:

1) Did u consider adding an injector instead of getting 6 bigger ones? Is so y did u choose to go bigger

2) How much more can ur highflow turbo do?

3) At what point do u reckon ull start to need to do internals?

1) No. Maxed out my stock ones at 220kw...so got bigger. Only $20 difference btw 550 & 840 so I just chose the bigger because I know there a pain to change an now i'll never have to do it again :(

2) the turbo can be pushed to about 22psi safely....but my head gasket can cope with that as its still stock.

3) most people say at about 280-300kw is where you should be looking into forged pistons (even though the stock ones are forged) and better rods (most people use linished GTR rod)

So by retarding the exhaust cam 4degrees, you gained 20kw atw?

Nice work.

aswel as re-tuning the car to suit :)

Yeah, I was over the moon! my tuner cant believe the power my car makes with stock engine an small turbo. Its averaging around 12.5 A/F ratio under load too which is still a safe tune. could get more if i leaned it off an ran more boost....but i dont want to. Maybe for a few runs on the Dyno at Autosalon to impress...hehe

thanks mate!

No real plans for further power. more power = bigger turbo & engine bottomend rebuild to cope = expensive

just hunting down some nice rims now an thats about it

just having fun with it this year, few deca days track day & drift training days....

by tunable i mean aftermarket. I run a microtech LTS-12 :(

looks like now with that little extra power im in need of a catch can....few reports of seeing blue smoke from my car after full throttle acceleration then backing off....its creating a bit too much pressure an the oils getting by, so catch can will rectify this.

thanks to those for letting me know

Yeah I was tellin Kris about that...I was behind you and was coppin a fair amount of blue smoke...thought somethin might have been wrong...then a few times right after the blue smoke would be a pretty thick puff of thick white smoke...

nice result mate....got mine sitting there and was going to to the belt soon...

I saw the blue smoke when u backked off...was going to pm u about it but forgot...

nice result...I hope I get some similar gains...will try with a de-cat setup just for the dyno to see the difference between my hi-flo cat and nothing...

    • Ok thanks..that was my second question if i can somehow bypass this even with Nistune(that is all i have right now...aparat from stock ECU. So with some aftemarket it can by "bypassed" or make it work?  I know there is Link or Haltech (mainly used). We have ECUmaster here so i will gather some info about it.
    • Yes. You will need to get the original boost sensor and wire it in. That is.... if you plan to use a stock ECU - even a Nistuned ECU. The Nissan ECU will not operate correctly without it connected. And yes, it will do annoying stuff like you are experiencing. You will almost certainly be better off with some aftermarket ECU, than trying to hunt down rare sensors.
    • Ok so ABS/TCS is "not" the problem. Yeah i know now about the ABS with Nistune(i told that to the Nistune guy) but iam not 100% why or why i dont have ABS. ABS cube is in the engine (always has been) but i had braked couple of times rly hard and brakes just locked and scream. Does all Skylines have ABS cube? That boost sensor https://www.sau.com.au/forums/topic/367633-wtb-r34-gtt-turbo-pressure-sensor-pics-inside/ Is this it? I need to ask but i have a picture of engine bay and i do not see that (100% is not in that place) If i do not have this the car can do what mine is?(cutting around 4000 rpm) Here is the pic of my engine bay(only one i have) BUT i think i dont have that cuz loom was used from my RB20DE NEO and i know (obviously) that it does not have boost control or any wire to that...) so maybe that is the problem? (i dont know for 100% if that car where the engine is from had that)...but i dont have the loom from that
    • I'm with you here. It's either loom has an issue, OR, injectors are not functioning properly. It could even be they're just constantly dribbling, hence the wet, but not firing.
    • Depending on how long the car sat it is very possible for injectors to be stuck open or closed, I'd get them cleaned and flow tested. Other than that, obviously when the loom changes and the car doesn't start any more....the loom is suspect so some tracing / comparing may be required
