Seriously contemplating putting my beloved R33 GTR up for Sale due to other racing commitments...

project build here:- http://www.gtr.co.uk/forum/148182-project-hosaka-black-gold-special.html

this car, although Race & Track ready, passed an MOT and was run-in on the road prior to me using on the track

it has been professionally mapped by Rod bell of RB motorsport up to 1.5bar boost. I reckon that would put it around 570hp. 1.8-2bar (with new wastegate spring needed) would see 630hp ish
I only run it between 1.0 & 1.2bar of boost on track and very little gets past me...
it has just completed over 2 hours testing at Donnington this weekend and ran faultless (easily passed the drive by noise test of 98DB`s)

Running just 1.0bar of boost, running federal RSR road tyres, with passenger and low boost, you can see the car is quick....

With slicks, no passenger, the boost wound up, and some aero matched up, I would say this would be a very quick car indeed for racing in its class.

the only video I have of the day sorry....:- Hosaka @ Donington trackday Nov 2013 - YouTube

this actual car was the Japanese Time Attack winning car in its class.
it was imported by MGT racing and I bought it off them.
it has since gained a couple of unofficial (as I was a OHW) podium places in Time Attack against cars with a LOT more power and on better tyres. :chuckle:

MORE

there are of course a few bits I need to point out, as the car is not perfect, so please don't be expecting a concourse condition car....

*the windows need a better fixing mod as they tend to pull out at speeds over 120MPH
*bonnet has some cracks it in due to it flying open once. it has been repaired
*front splitter is a bog standard jobby and looks a little untidy due to a hole in it for the towing eye.
*its fully stickered up - although I could be persuaded to remove these
* needs new straps for the front floating discs. there is a noticeable amount of peddle judder - but does not effect the braking in any way
*front passenger seat ideally needs to be lower for those over 6ft struggle to get in with the roll cage.
*interior paint job is not the best, but perfectly acceptable.

other than the above, she is great, looks fantastic and handles wonderfully...

it can easily be put back to road spec, if that's your thing.

there is loads more bits (too much to list really) on this car that I have either forgotten about or have been done by RB that I cant simply remember. I do know, if you were to build this car yourself, it would cost over 70k.

I am looking for offers around 28k - which considering what you get, is a bloody bargain !!!

if it does not sell by the beginning of the season next year, I will be breaking the car...which would be a total shame considering its history and the amount of work gone into it...:(

some vids here....

watch from 6m.20s on for 1st vid. couple more to follow...

Oulton Park Nov 2013 - YouTube

car was running just 1bar of boost and on road tyres... guy was following in a 500hp 2.3 stroked, seriously modded Evo running on full slick tyres, just to give you an idea of how quick it is....

With semi or full slicks and 1.6 bar, this car is Silly Quick ! hahahah...
