Brought some Bosch 1000cc injectors ready to go.

Took a chance on a ebay top feed rail kit that turned up today and of course aint close to fitting. So back on the hunt for a top feed rail setup again.

try injectorsonline.com , they sold me a cheap rail for $100 to go with my xspurt 1000's, needed a return hole welded which didnt cost much to do..

that was a topfeed rail which fit my r33 with some machining of the spacers..

I think Plazmaman do a nice fuel rail now too? I ended up with a HKS item but swear i saw one from Plazmaman recently...

TIME FOR A UPDATE.

Its been a very long time since anything has happened with the car.

With all the flooding going on around town kinda had more important thigns to take care of then car stuff. With everything back up and running the car went in for injectors and a tune........didnt go to plan.

I ordered a set of bosch 1000cc 11mm injectors and a SARD 11mm rail after the first rail didnt fit, Not thinking ripped the injectors out of bags and threw them into the bench tester to check flow rates, patterns etc. Not realiy paying attention but they had sent a set of 14mm injectors by mistake. So had to order some adapters to suit and wait.

In the mean time just been doing little touch up things. Remade the catch can breather hoses in 200 series braid to match the rest of the speedflow.

Car is booked in on the 18th of april for another shot at tuning. With any luck will have some results and Then its time for the owner to fill his pants when its on boost

Spot the mistake made by a person who isnt me

Very nice - what fuel are you going to be tuning this on? The 1000cc injectors aren't going to be big enough if you are going to be leaning on it hard on E85... a chap over in NZ made 470kw @ hubs on a similar engine setup in NZ on pump gas, so a huge amount of air can be flowed through those GTX35Rs on an RB25 built to suit :O

Going to just be pump 98 for now until E85 is availble in town. Yeh they wont allow much tuning but by the time E85 is here 2000cc injectors will be even cheaper so can just drop them in and go.

Plan is just see how it responds on pump fuel and wind boost in until its not safely possible.

Here's a workshop blog update from a similar setup doing a similar thing, be interesting to see how your results compare:

Being hub dyno they show higher number but if it can manage 400kw on 85 on a roller dyno, I think the owner will be happy.

after all he's only used to just over a responsive 300hp......will be funny to watch his reaction first time it spins 3rd

Yeah the hub dyno reads higher than what you are used to - but make no mistake, 470kw on a Hub Dyno is still very big power ... that is well and truly enough to get a full weight R33 deep into the 10s with sticky tyres on BP98, I'd expect it to hit 400-420kw on a roller all other things being equal. I daren't even guess what it'd make on E85!


Without VCT that turbo was really quite laggy, though

    • You Gregged a whole racetrack!?
    • Look for broken wire or bad connector at the motor. Might not be it, but is worth starting there, as it is easy.
    • Hi everyone, I’m having an issue with my R32 GT-R. Sometimes, when the car goes over a bump or experiences some vibration, the 4WD warning light comes on the dashboard. When I check the code from the control unit in the trunk, it shows Code 19 – ETS Motor. However, everything seems to be working fine — if I turn off the engine and restart the car, the light goes away and everything functions normally. Has anyone experienced this before? Where should I start troubleshooting this issue? Thanks in advance!
    • I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...
