Hey guys,

I recently had my Stagea on the dyno to diagnose a misfire problem. In the end (after the dyno tuning session) it turned out to be a coilpack. The problem is now fixed and I want to get back to the workshop for a touch up tune and power run.

Now the Stagea made 156awkw at 4,100 rpm on 10psi before the misfire interfered. As a guess, what do you guys reckon it could/should make now it can rev thru to redline under load?

:)

To assist, the Stagea is running Nistune, HKS 2530, HKS pod, cai, fmic, 10psi, 3" system from turbo, manual box, stock injectors, stock afm.

Taking a guess off a dyno sheet with similar mods (tho not exact, and I know all engines are different):

This engine with 205awkw @ 6,600rpm made 140awkw @ 4,000rpm (of thereabouts)

Therefore, using interpolation, at the same 6,600rpm I may be making 228awkw.

Or am I being hopeful :worship:

I've just purchase a Z32 afm too. Going to wind things up to 14psi. :)

I hope you aint running a stock fuel pump trying to push those figures....

Genuine Walbro :)

Stock injectors ... I should consider upgrading. :happy:

I do have a Sard FPR fitted atm if necessary ... but I'm not going to rely on it. At the end of the day, I told my tuner I want whatever useful power the car can make without maxing out the injectors. So I guess injectors is next on my list. Should do that before I go back to the tuners. :worship:

      yeah i agree paint match stops it from standing out so much, oh that's actually really good to know i was wondering if it would help with air flow now actually having an outlet in the bonnet. Will have to focus on ducting into and out of the radiator now to make the most of it.

      I would paint match the whole thing to avoid unwanted attention  I had a similar bonnet, paint matched, on my old R33 GTST, but mine was a fibreglass jobbie made by Blitz in QLD, they work extremely well for radiator efficiency and under bonnet temps

      Does anyone run this kit with factory plenum? Does the adapter and bosch tb fit under factory strut brace? I wanted to get this setup before going forward facing manifold. Thanks

      small update time, after always wanting a "cool" looking bonnet for my car and always struggling to find one for the series 2 that i liked and wasn't an insane amount of money. Saw one i liked on RHDjapan from D-speed in Japan the price was very good for a carbon bonnet so good infact i was a little unsure how much i trusted it, decided to bite the bullet and with the help of jesse streeter in not long at all it was at my door. Once it was delivered i ran in from work and quickly unboxed it and to my surprise the quality was actually pretty good i quickly removed the old bonnet and placed on the new one to test it out and even the fitment wasnt too bad at all. Then decided to paint the little grille in the bonnet black to stop it sticking out so much.   I decided to not mess around with the hood latch and just install some aero catch hood pins, having never installed them before did some YouTube university classes and i was good to go. fair to say it is not a fun job at all from making brackets so the pins sit nicely and actually cutting through the bonnet but also being very scared of cutting the holes too big it took wayyyy longer than i would like to admit but finally got it there. Then it was time for a quick test drive to ensure the latches actually worked and thankfully the bonnet looked very stable. I still think paint matching the bonnet and leaving just the part that sticks up as carbon would help make it all look alot neater as im not sure how i feel about all that carbon on a very fridge white car but will leave it as is and see how i feel with time.

      Mistakes were made, my R34 Story

      I think it's bound to happen, you finally get it all perfect, and bam, something will happen. I took a while to get a Commodore rear quarter repaired where a P Plater clipped it. Two days after getting it back, Sarah wiped it out on a concrete pillar in an underground car park... This is why I take forever to repair them, it stretches how long until it gets bent again... 😛
