Its a strange one Marcus. On the dyno it's at the same rpm every time (7000). It's not a hard cut or a "rpm cut", but a faint miss. The best way to describe it would be three softest rev limiter ever.

In the road however, depending on how cool it is, it may happen earlier. Gtr Sean drove it before we left for the nats and it missed at 5800. Stupid car.

Car is finally booked into Insight on the 19th of April for the ECU, fuel system and sensor wire in plus the tune. Thats the good news. The bad news is that V-cam aint gonna fit with my pistons and ho

Small update.... ITS RUNNING. Fired first go! Smells like burnt dust apparently .

A 9174 would just make the EGP pressure issue worse and in my mind it seems like a bit of a GT RS shit going on. Not that it's horrendously bad (It wouldn't be no twin buttplug pressures), That's NOT

Make sure you get Yavus to check the settings for ignition/dwell etc. It's the only thing (computer) that has been changed....

I was there today. Tried that one too. :(

Didn't you just replace the alternator? Could the new one be playing up?

Not a chance of that ! 20 mins before it came off my car and it was pumping at full power output. She is almost brand new unit and designed for high power GTR's.

It should be boosting electrical output.

Chuck it on Paul and recheck all your earthing.

CDI time !

Naw wouldn't go that route either. I have a 500R on my 'mini-me' version of Paul's and mine has break-down once it's hot. Hard to nail this one down. Just not sure how to get a hotter spark with lots of amps to make it fire reliably.

Was good to see you lay a decent time there Paul. I'm spewing a bit cause I had to drop out of play so soon. Might have been able to give you at least a little run on times.

Is that not more likely coils then? What coils were you driving with the 500r?

Yeah, your issue is a strange one considering you have tried another set of coils and it didn't change anything :(

I reckon the issue might be the ecu, specifically the fact you're running wasted spark... it'll be over working you ignition system IMO

Thing is, it was perfectly fine 9 months ago. It's pretty much a standard setup bar the igniter which has been modified. Joey has three exact same setup and no issues.

Hi paul

How does the car feel with the higher comp and tight squish ?

Feels really grunty. No need to rev it. I would have liked more comp but without custom pistons it wasnt going to happen.

It will be a few weeks before the tune is finished.

paul,

have you whacked another set of working coil packs or an igniter on the car to test yet?

Yep with coils that just did 425 rwkw a few hours before. Changed ignitor box off the same car. Changed plugs. Then I yelled at it!

Fancy trigger wheel all in check?

Doesnt seem to be any issues there man. Nothing on the logs.

I'm sure it's something silly thats been overlooked due to a serious lack of time.

      Rb head oil drain dimensions

      By Papichulo96 · Posted

      Bump on this to not make another post, had a ‘head drain’ leak on me and have the engine out as we speak. Planning on just putting a new freeze plug back in , plug the tapped holes and just be done with that headache.    Now I still want to relieve pressure to allow oil to pass down the blocks returns easier. I’ve seen catch cans with multiple vents help folks with this issue on this forum.  I’m wanting to make my own. I have some pictures here of my setup if anyone can help how I should plumb and design the catch can I would deeply appreciate it !   rb25 Oil upgrades: 1.0mm restrictor n1 pump/billet gears extended crank collar  extended sump with trap doors/w welded fitting

      Need AC Compressor for R32

      By GTSBoy · Posted

      The Frenchy's kit is the way to go forward. A modern compressor that weighs about 1/2 as much, is at least twice as efficient, and will do a good job on R134a. And of course the kit has everything else you need to connect it up and have it work properly.

      Need AC Compressor for R32

      By Zabuza · Posted

      Hey all , I am in the process of having the AC system in my r32 GTST converted from r12 to r134a and I’m being told my compressor has gone bad and I will need a new one. I was wondering if anybody has any suggestions for what is the best route to go aside from dropping $1500 on a new oem one? I did see that Frenchy’s performance garage offers a kit to mount a Toyota compressor, has anybody actually used this kit on their car? Or is there anywhere I could purchase just a clutch? Any help is appreciated.

      Help Understand GTT Boost Setup

      By GTSBoy · Posted

      Well, your RB20 ECU loom won't have wires for the boost solenoid, that boost sensor, and possibly one or two other things. There could be differences in seemingly random things like the charcoal canister purge solenoid, because the 25DET has to handle boost in the vacuum system and the 20DE does not. I don't know - I haven't looked. It is very likely that all the most important things are same-same, being the main sensors like AFM, CAS, etc, and the injectors and ignition. Not that you'll need the AFM for the Haltech anyway. I would suggest that you would seriously want to sit down with the pinouts for both ECUs and just go through them and highlight green what is the same, orange what is different/missing, and make a plan from there. It's not going to be difficult. It will either be the same or need to be fixed.

      Help Understand GTT Boost Setup

      By Sxnjeet · Posted

      yeaaa that's why I haven't done any wiring to the stock ecu harness because I have the haltech, but then that leads me to the other question of "is the pnp harness really plug and play?" or would I have to still switch some pins/wires over because the pnp is for the rb25det neo harness, and not for the rb20de neo harness. was really hoping to find something to spoon feed me since so many people have done rb20neo + t conversions, but man this is rough.
