I just copied this from another post...... I just ran our NITTO R34 GTR at the drags on saturday at Willowbank. Ran a 10.39@142mph on Hero 255/30R20 tyres, Tein Monoflex coilovers, OS88 gearbox, standard 05U rb26 with precision 7675 turbo making 845hp @ all four wheels. 1.77 60ft 4.69 330ft 6.9 1/8mile (107mph) 8.799 1000ft 10.39 1/4mile (142mph)

The breather setup on Nitto is very well thought out. It has catch can to sump drains, block vents to catch cans, block restrictors etc all to vent pressure and ensure that the oil stays in the sump.

Up until 1 month ago, it had standard sump with the oil just filled to the top line on the dipstick, as you would with any car. When we changed the diff ratios, we installed a 9L sump and again filled it to the top line of the dipstick. WE HAVE NEVER OVER FILLED THE ENGINE WITH OIL!

What she said!! ^^

Yeah it does make a big difference, but if I show everyone, then they will all do the same thing!! hahaha. But in all seriousness, an extra 1000rpm of spool is pretty handy.

So lets clear up some of the rumors...... The original Nitto 2.7L blew a head gasket at power cruise in 2010 when we were running the GT47R through a mixture of too much boost and also too much coolant temp (it copped a cainning!). We didn't time to repair it before Autosalon, so we decided to run the car on the dyno as it was. On 40+psi it made 1072hp, but had sucked in some coolant and damaged a rod. This caused a rod failure AFTER autosalon at a photoshoot under light load destroying the N1 block. The engine was removed and replaced with a standard 05U rb26 and a T04z setup as we wanted a street style setup and we had spent a lot of funds to get to that point. The stroker kit was inspected and any damaged items were replaced and since then we have sold/fitted the 2.7L into a customers car. For the past 2 years we have been running the standard engine and with great success, using E85 and generally running around 30psi boost. I now personally tune the car (I didn't with the 2.7L engine, it was one of my staff) and switched to a HALTECH ECU. The T04Z was getting boring, so we had a play around with a few turbos (doing more R&D) and eventually we installed the Precision 7675. I wanted to see how far we could go with the standard components as 2J's are always referred to as unbreakable and I thought it was time an RB got some credit! It went into the 700's (hp) and I was having a chat with Mark @ Godzilla. I asked if he thought 800hp was possible and he kinda laughed at me. I dont mind a challenge, so I had a new goal of 800hp. We got to 805hp and this particular engine was hanging in there pretty well! We had run 30psi, then 35psi, then 40psi! it just wouldnt break! Hell we even threw a 100 shot of gas on there for a bit more response. To me it is experimenting, but on my own gear. It allowed us to play with the Haltech ECU and use many more of its features other than just timing and fuel. It runs everything including the NOS, flat shift (when we put the sequential in there), coolant pressure protection, complete engine protection (temps, pressures etc) full EGT on each cylinder and also post turbo....the list goes on. We are the first to realise the standard engine is a timebomb (yes we are realistic!) and wanting to do something different instead of just another 2.7L (as we had already done that), we have been building a 3.2L Nitto engine over a period of time whilst using the standard engine. This engine is getting the works including sleeves, billet main caps, 4wd girdle plate and a few other little goodies. This will be combined with a new custom head (bigger and better!) and a larger precision turbo. Our goal is to build an amazing street car with 1000hp at the wheels that can be used at Powercruise events, off street drags, air strip run, 1000m races etc. We love our 34 GTR so stay tuned for more updates as we fit the new engine and attend more events, showcasing it performance.
