Got my R32 GTR's ecu upgraded to a Vipec recently. With Turbo-back exhaust and R34 turbos and HKS EVC boost controller set to 14 psi, it's making 205 atw kw. I would eventually like it to make around the 250 atw kw.

My question is what's the most cost effective upgrade to do next?

My mechanic suggested to upgrade the fuel system and a re-tune after that. Other are saying cams and more boost.

Any suggetions?

get a new mechanic.

Fuel system is good for over 250rwkw. Maybe change your fuel pump to a newer one

Cams are not needed for a while yet....

Just up the boost and get it re-tuned. Check for any restrictions too. (exhaust etc)

being a tax payer how about using the money to lobby the govt to spend our money on infrastructure so the nation has an asset rather than a larger current account deficit OR more tuning?

That worked....................lol

an hour of dyno time? or a few hours?

8 deg retard on exhaust and 4 deg advance on inlet generally works best on stock cams.

these figures are crank degrees so 4 and 2 on the cam wheels.

id buy a Techedge wideband and have it hooked up to the Vi-PEC. With the autotune function enabled it will constantly analyze and alter the tune for optimum results. Or if you want a dash style interface similar to a power fc handcontroller for the Vi-PEC a EM PRO II engine monitor would be a wise investment.

leave it to the wideband O2 control. the autotune doesn't alter the fuel map properly when the cells are changing as rapidly as they do driving around town. (i have tried it and it messes the map up)

      My thought is if you were just moving it forward and the upstream geometry remained the same, then no difference at all. But because the current one has the filter direct into the AFM inlet, you effectively have the best chance of a completely symmetric air flow profile upstream, and in, the AFM, whilst the aftermarket inlet thingo has a (small, to be sure) bend between the filter and the AFM. That would bias the flow to the outside of the bend (downstream of the bend) which might well reduce the size of the signal seen by the AFM, for the same total flow rate. Having said that: If you're proposing to make your inlet look like a hybrid of your existing one and the aftermarket one, such that there is no bend where the filter is clamped on... then I say it will be just fine. If there is going to be such a bend, then, if you can align the insertion of the AFM blade such that it is at right angles to the plane of the bend, then there is a better than even chance that the centreline velocity where the blade is will remain more or less the same, and the velocity will just be a little faster to the outside of that, and just a little slower to the inside. **This is not professional investment advice and you should consult a suitably qualified ouija board, tea leaves or the intestines of a goat for more accurate prognostication.

      Blue/grey smoke after idle

      By pacman_1219 · Posted

      Hi Tao, Thanks for your reply.  It's been a while and I managed to get the valve stem seals replaced with the head on the car.  Unfortunately this didn't solve my issue, the car still smokes a lot after idling (to be honest during idle you can see a bit of blue smoke from the exhaust), same after deceleration. I will try disconnecting the valve cover breathers, do I leave the PCV valve in? By engine oil drain pipe, do you mean the turbo oil drain?

      My guesstimate, with no real numbers to back it up, is it won't effect it greatly at all.its not a huge change in position, and I can't see the air flow changing from in turbulence that much based on distance, and what's in front of it. Johnny and Brad may have some more numbers to share from experience though.
