After spending the past 4 hours reading through this thread, I have come to the conclusion on a few things:

1) I should probably get back to work

2) There is a lot of things that I still do not understand

3) I plan on building a 34 GTR myself, but I have much better ways to spend 3 years and god knows how much money on this kind of indepth project. Though, I admire the patience, skill, knowledge and workmanship that has been put into this magnificent machine. This is truly remarkable and will hopefully change the future of modifcation of RB engines, and cars in general - especially if this venturi manifold does spool that turbo in the way and at the engine speed that it should.

Just a couple of questions Bobby. I know you have probably done many more calculations than I have on the following question/comment concerning the air compressor to try make boost on idle.. We had a shop engine we were trying to do the same thing to, and we could only make a measly 5psi after having 3 lines of shop air tapped into the manifold pointing directly at the impeller - obviously we could only get such low compression because the impeller runs off volume rather than pressure. How do you manage to overcome this?

Also - 3 years is a long time to be working on this project, how did you stay motivated up to this point? I certainly would have lost interest and even reading the thread I skipped a few pages at the end haha.

You were involved in building one of my mates' r34, I think you named it goldfinger. I can see now why he chose your company to build his car because you obviously have the willingness to go the extra mile for your customers as shown in his car, and in this thread. +1 to you and to your team. If I ever have the money (haha not in my lifetime) to do something as dramatic as this, it will be a no brainer who to go to. Good luck with the rest of the build.

Thanks mate.

I will have to ask John in more detail on how he is going to set it up as i know using co2 works as it expands 500 times when it hits heat.

I have stayed positive as the fab work was amazing and i said to myself i just have to stick it out not more the time frame.

Khris car comes back tomorrow will post up some pics of the finished product.

Great effort you must be chuffed!

Regarding your M800, did retain the original ecu for anything minor or has it been removed completely?

I ask this as I have been running both for the last 6 years.

The workshop that fitted/tuned it said it still needed both at the time.

Fantastic car anyway and all the best with it.

Its full stand alone m800. Next year we will be installing the m150 again stand alone

Hello Bobby,

I am very interested to know what you did to make it stand alone.

I think my original was left to run Atessa with the TPS signal.

Realise this all costs money and am more than willing to pay for a wiring diagram and the additional MotecM800 setting.

All the best with the car

Mike

    • Given you're running a 2.8 and my 2.5 is not really like for like, I suspect there could be a bit more timing you could give it. What is the kW yield per degree you're putting through it? Here's my E85 map to give you an idea, where it was I could still get another 3~4kW per degree thrown at it.  
    • It turns out that Setrab make a fan specifically for the oil cooler which is great and I've installed it with minimal swearing. I removed my 2x 12in push fans from the front of my aircon condenser and wired them into this. My main thermo fans kick on when I use the aircon anyway and would effectively already be working as puller fans through the condensor which is infront of the rad. The push fans (understandably) didn't really do much in the config they were previously in so now they're out. Now we're on to the "Oil fan doesn't really do much either!". Yes I'll duct it next if it does nothing in heavy use which it shouldn't. But hey, the object exists and fits great and is cool. Let me have this. The car is still in the "do my fittings leak oil now? do my wheels actually rub?" phase. I did a spirited drive on them and didn't hear or feel anything. Then I got back home and noticed there were grind marks on the inside of the rims, though I couldn't see where they were touching I got out the grinder and attacked the suspects. Note: I do not know how to use a grinder. Then I realised I had dragged my new rims across my concrete driveway before I did this drive. I didn't think I had damage at that time when I briefly looked...... but remembered this occurred after I did all the angle grinding. The grinding on the wheels in some very specific spots. It's not around the whole rim for example, which lines up with dragging it across concrete more than hitting a suspension component for even 1 full rotation. So everything is currently painted and taped up and I need to test it some more to see if it really IS rubbing, but from inside the car it doesn't feel like it is. In other news I attempted to do a before and after comparison of the heads/cam upgrade thing. Dynos lie, everything is in different measurements. Here is the data from the sandown back straight. Car go faster than before. Vroom vroom.
    • Here's my base ignition. +3 correction to redline when shooting water/meth which is always on. Looking at my old ignition table, I should be able to add 1-2 degree's next time I'm on the dyno.  Let me know your thoughts. 
    • Given what I know now - same haha, but this was 12 years ago with second hand 740cc Nismo injectors in my S15 daily, I was too busy hunting elsewhere for the issue to even look at the injectors, running through some cleaner was a happy coincidence haha
    • Not a terrible idea. But if I ever had concerns that my injectors were sufficiently dirty to be causing me a problem, they would be out of the engine and onto the actual injector cleaner/testing bench.
