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

    • I know people cry at the price of the Getrag 12-14k for a conversion now, but it really is a nice mid point. Not going to get change from 10k on a gearset installed.  $30k++ for sequential.   I know you run the risk of a damaged used one and parts are hard to get but as a street car gearbox its really hard to beat. If you enjoy a more traditional manual, its the choice no question.
