Good to see this kit available at last! Have to say 450kw is somewhat underwhelming but the extra capacity will have to translate to more power. It will be great to see someone build either a drag or a circuit car and see what it is really able to do!

please note this is on pump fuel with a rb25 head

another note is that the builder needed to get a new clutch because of the extra torque

hope to build this in the future.

I am sure it is capable of much more. The 3L going into my Stagea is looking too small already!

Its a sad day when 608hp/450kw doesnt impress.

That said, im sure Brad couldve got a T51RSPL on there at 2 bar on e85 if he wanted a big number, surely the point here is just crazy low end grunt more than a big hp number :)

yeah id like to see the power curves on this engine.

he was making close to 580-590hp with the 3.0l so this is a great improvement especialy how it is relativly cheap comapeared to a full house jap bottom end.

probly total cost for the whole engine is 6k - 10k by guesstimation.

There is a price at the top of $5500 for the rolling assembly so you would have to say closer to 10k all up ready to go depending on how far you go.

RB34DET Results

RB34DET 'vs' RB30DET

The RB30DET boost and power curve is in green and the RB34DET is in red

Resize%20of%20142JHK%20power%20vs%20boost.jpg

A comparison between the old RB30DET engine and the new RB34DET stroker engine is complete. The two engines are identical in every way except for the new stroker crank set up. The purpose of building two near identical engines was the only real way to make a true comparison between a RB30/25 and a RB34/25.

We arent trying to make the most power or we wouldnt be using pump fuel and a medium frame old school T04Z, we are trying to make a comparison.

Straight from the horses mouth.

    • @Haggerty you still haven't answered my question.  Many things you are saying do not make sense for someone who can tune, yet I would not expect someone who cannot tune to be playing with the things in the ECU that you are.  This process would be a lot quicker to figure out if we can remove user error from the equation. 
    • If as it's stalling, the fuel pressure rises, it's saying there's less vacuum in the intake manifold. This is pretty typical of an engine that is slowing down.   While typically is agree it sounds fuel related, it really sounds fuel/air mixture related. Since the whole system has been refurbished, including injectors, pump, etc, it's likely we've altered how well the system is delivering fuel. If someone before you has messed with the IACV because it needed fiddling with as the fuel system was dieing out, we need to readjust it back. Getting things back to factory spec everywhere, is what's going to help the entire system. So if it idles at 400rpm with no IACV, that needs raising. Getting factory air flow back to normal will help us get everything back in spec, and likely help chase down any other issues. Back on IACV, if the base idle (no IACV plugged in) is too far out, it's a lot harder for the ECU to control idle. The IACV duty cycle causes non linear variations in reality. When I've tuned the idle valves in the past, you need to keep it in a relatively narrow window on aftermarket ecus to stop them doing wild dances. It also means if your base idle is too low, the valve needs to open too much, and then the smallest % change ends up being a huge variation.
    • I guess one thing that might be wrong is the manifold pressure.  It is a constant -5.9 and never moves even under 100% throttle and load.  I would expect it to atleast go to 0 correct?  It's doing this with the OEM MAP as well as the ECU vacuum sensor. When trying to tune the base map under load the crosshairs only climb vertically with RPM, but always in the -5.9 column.
    • AHHHH gotchaa, I'll do that once I am home again. I tried doing the harness with the multimeter but it seems the car needed a jump, there was no power when it was in the "ON" position. Not sure if I should use car battery jump starter or if its because the stuff that has been disconnect the car just does send power.
    • As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.
