Motorkhana Bnr32?

[CrimsonLey]

I've been searching for the past 15-20 minutes trying to find more info about motorkhana builds for 32-Rs.

I have a 89 BNR that I'm going to send over the USA eventually. It's very much stock except for a few bolt-ons, etc so I don't want to modify it much (stock 32-Rs are getting rare). I decided to run motorkhanas because of the ability to have fun while not causing too much stress on my old GTR.

From searching on SAU, I see that hardly anyone races their GTR in motorkhana. I found more that GTS enjoy the sport as opposed to Rs. It seems that more GTRs are rally'ing, road racing, etc.

I don't mind road racing (HPDEs in USA) in 'stock/street' class either but motorkhana is a lot cheaper and more accessible so I'm leaning more towards that.

Is the GTR a bit of overkill for motorkhana?

Should I just focus more on a road race build?

well, unless I misunderstand autocross is a bit quicker and more open than our motorkhanas, so it won't be so bad. They are a little large and heavy for local khanas, but still great fun

In the end, you'd still get eaten by an evo or some sort of mini special

Thanks, mate.

I've done autoX'ing in the past and loved it but I suppose it's not as popular in Oz like it is in the US. I remember a lot of younger guys were autoXing and usually the older drivers were doing HPDEs

No way overkill! I've competed in GT-Rs for the last 18months at our Vic SAU days (max speed is around 140, avg about 60-80) - and the GT-Rs go just as well as the 180s etc. Just gotta learn how to drive them and set them up really.

Good diffs, suspension & brakes will make the world of difference. Of course power will also help and either way if i was you - change those turbos before they fail and potentially take the motor out.

For a good khana setup if you put on say:

Garrett -7s / PFC/ Tune

Nismo Diffs & transfer case rebuild & a high volume sump

18s or 17s with good rubber

Brakes (perhaps the GB? Link in sig)

You'll have around 300rwkw, and it will be super responsive & nimble (well, as nimble as a GT-R can be) and handle like a RWD or AWD car as the diffs lock hard and are good for tight stuff to get the ass around and then straighten the wheels and bury the pedal and 4 wheels drag you out

I had larger -5s but for that type stuff on a 2.6ltr they are too laggy.

You saying you competed in morokhanas? I'm not sure what Vic SAU days are.

I definitely want to setup the GTR for maximum grip while still maintaining the originality of it.

Thanks for the build-list. ATM, I'm think about doing a simple 33-R brembo upgrade as opposed to anything to crazy.

Just youtube "SAU-VIC DECA" - there will be heaps of footage of skidpan and also the back-track type stuff. Not your traditional stuff, little more speed involved but I managed to get a R33 around pretty well when i remembered which way to go

33-R brembo's are overpriced and a waste by the time you get new rotors, pads, rebuild (and paint) the calipers etc.

^I can get them fairly cheap in Japan. Believe it or not but I have a set of front R34 Brembos before I found out that I would have to drill a larger hole. lol.

I watched the videos, mate. Thanks for the info.

Back on the subject of racing the GTR. What are some good engine supporting mods that I can do to help the engine longevity? For example, oil sump, ceramic coat the block, mine's cam baffles, Tomei oil orifice, etc. I want to keep everything stock but I do want to add lots of supporting mods.
