Hi again,

the turbos are hks gtr-s but i was told they were rated at 450hp, and other sites I have researched agree with that.

When in doubt, refer directly to the HKS goodsmaster catalouge - They are not rated at 450ps so a workshop should not be making those power claims.

I would definitely reconsider your plans and any associated costs/quotes/budgets as what you require won't be cheap. I would also recommend a more suitable workshop for such extensive mods, unless you have plenty of time to wait and money to burn.

Either way a 450rwkw GTR wont be cheap to run and maintain-mine only had 370rwkw and had a large appetite for gearbox's. I fixed the problem with a full OS Gikon set. In hindsite should have spent all that money on something else >_<

Im at a time in my life where I can burn a little cash off having fun but if you can tell me more about the box you bought - where from, how much, it would be appreciated

I may have one for sale...pm me if interested

again....what oil pump and sump are you planning to run with this combo??

definately be used on the street. will see the track regularly too. the car is almost ready. will be going for its dyno run on wednesday. had it on dyno last friday and it hit 380 kw no prob. graph was climbing steep but noticed small amount of oil coming from one of the turbos so stopped the run. Both turbos now back @ shop getting new seals. warranty job. turbos back on car tomorrow. will post graph hopefully wednesday night.

Just got the GTR back on Friday morning and after a few days on the gold coast have now driven it up from brisbane to townsville. ITS AWESOME. HILLS MOTORSPORTS have done an awesome and thorough job. Im very impressed. 447 kw at the wheels. 1012nM of torque. I ended up having to get a new gearbox and opted for the P.A.R. straight cut box. Feels smooth to change but does have the usual whine in 1st 2nd and 3rd. full kit cost me $5300. I will running it this week end so i will keep you all informed of my 1/4 mile times. Must repaet again what a great job mark from hills did. I know there are some people in here who think otherwise, but he has impressed me.

Ended up sticking with the gt-rs turbos. they come on hard at around 4300rpm and go hard to my 8600 rev limit. I will post pics of my times on monday. Im aiming for mid 10's until i get used to launching it and hopefully my times will drop a bit more soon. I have done a couple of practice runs on an old dead end road out the back of townsville and using my rev/speed monitor i got down to 10.72

    • You won't need to do that if your happy to learn to tune it yourself. You 100% do not need to do that. It is not part of the learning process. It's not like driving on track and 'finding the limit by stepping over the limit'. You should not ever accidently blow up an engine and you should have setup the ECU's engine protection to save you from yourself while you are learning anyway. Plenty of us have tuned their own cars, myself included. We still come here for advice/guidance/new ideas etc.  What have you been doing so far to learn how to tune?
    • Put the ECU's MAP line in your mouth. Blow as hard as you can. You should be able to see about 10 kPa, maybe 15 kPa positive pressure. Suck on it. You should be able to generate a decent vacuum to about the same level also. Note that this is only ~2 psi either way. If the MAP is reading -5 psi all the time, ignition on, engine running or not, driving around or not, then it is severely f**ked. Also, you SHOULD NOT BE DRIVING IT WITHOUT A LOAD REFERENCE. You will break the engine. Badly.
    • Could be correct. Meter might be that far out. Compare against a known 5 ohm 1% resistor.
    • @Murray_Calavera  If I were an expert I wouldn't be in here looking for assistance.  I am extremely computer literate, have above average understanding on how things should be working and how they should tie together.  If I need to go to a professional tuner so be it, but I'd much rather learn and do things myself even if it means looking for some guidance along the way and blowing up a few engines. @GTSBoy  I was hoping it would be as simple as a large vacuum leak somewhere but I'm unable to find anything, all lines seem to be well capped or going where they need to be, and when removed there is vacuum felt on the tube.  It would be odd for the Haltech built in MAP to be faulty, the GTT tune I imported had it enabled from the start, I incorrectly assumed it was reading a signal from the stock MAP, but that doesn't exist.  After running a vacuum hose to the ECU the signal doesn't change more than 0.2 in either direction.   I'll probably upload a video of my settings tomorrow, as it stands I'm able to daily drive, but getting stuttering when giving it gas from idle, so pulling away from lights is a slow process of revving it up and feathering the clutch until its moving, then it will accelerate fine.  It sounds like I need to get to the bottom of the manifold pressure issue, but the ignition timing section is most intimidating to me and will probably let a pro do that part.  Tomorrow I'll try a different vacuum line to T off of, with any luck I selected one that was already bypassed during the DBW swap.  (edit: I went out and did it right now, the line I had chosen did appear to have no vacuum on it, it used to go to the front of the intake, I've now completely blocked that one off at the bracket that holds several vacuum lines by the firewall.  I T'd into the vacuum line that goes from that bracket to the vacuum pump at the front of the car, but no change in the MAP readings).  Using the new vacuum line that has obvious vacuum on the hose, im still only getting readings between -6.0 and -5.2.  I'm wondering why the ECU was detecting -5.3 when nothing was connected to the MAP nipple and ECU MAP selected as the source. @feartherb26  I do have +T in the works but wanted to wait until Spring to start with that swap since this is my good winter AWD vehicle.  When removing the butterfly, did it leave a bunch of holes in the manifold that you needed to plug?  I thought about removing it but assumed it would be a mess.   I notice no difference when capping the vacuum line to it or letting it do its thing.  This whole thing has convinced me to just get a forward facing manifold when the time comes though.
    • Update: tested my spark plugs that are supposed to be 5ohms with a 10% deviation and one gave me a 0 ohms reading and the rest were 3.9ohm<, so one bad and the others on their way out.
