My R31 Grip Car Build

[Matty 31]

After having a drift car for a couple of years (and doing a stunning job of writing it off), i decided it was time to build a new car, but with grip laps in mind. Less chance of me majorly damaging the car if i go offline. I am currently on my second shell as the first one id picked up was a bit ragged (and i really wish id picked up the other car he had.....found out it was an ex Gibson Motorsport HR31 shell, unused in racing but ready to hav stuff dropped into).

wow.. this will be interesting to see what sort of machine this turns out to be... not many, if any, aussie R31s built for grip duties..

kudos to you for doing what i could not.. spend ridiculous amount of money in unkown territory.

Hey man this could be interesting to see how it gose. Ill be keeping an eye on this on

Might give me some ideas for setting mine up for grip work for the few time i will try it

[Matty 31]

thanks for the positive comments so far. In essence, sinking 10k into it really isnt that much to sink into a 31, could easily spend more if i wanted to go completely stupid. a lot of the money is being saved by doing a lot of fabrication myself (or at least with the help of my mates). Plus i know my way around a 31 pretty well now, so will try and develop as much as i can before moving chassis

the important stuff always costs, but ive worked out it can be used again in future projects (seats, steering wheel, fuel cell, engine/box package, suspension depending on what chassis i decide to move to in future)

[lawler]

I must say 31 arnt that hard to work your way around.

Tho I know what you mean about 10k I think mine owes me about 12k already.

Was there anything off your drift car that was worth saving for this one?

the only thing ive really kept from the skidder is the motor, swaybars and the diff. was only running a mid 150rwkw setup with stock turbo in that car, so stock turbo and RB20 box / clutch were really going to be out-ranked here. I just had some generic jap Bride copy seat and a Personal wheel and a 4 point harness.........and some cheapie gauges that were effing useless half the time

[lawler]

Ah ok im keen to see how this gose. Got much elce done to it yet?

[Matty 31]

not a lot has been done, as there was an issue with the shell rego wise (long story, but i want to be able to use it for tarmac rally down the track so need to be able to register it), but thats been sorted out. put a hold on things happening for a good 7-8 weeks

[Matty 31]

pedals roughly put together for the purposes of photos, and pics of my new wheel with the hub kit attached

[jenkies]

i will be following this!

[lawler]

Dam those pedals look cool

[Matty 31]

this weekend im utilising to the max (i have an RDO monday, so 4 day weekend w00t). getting some dry ice and doing the sound deadening, and removing the rest of the un-neccesary crap. brake pedal and booster / master cylinder has to come out.

got hold of my new coilovers tonight, so they might be heading towards being bolted in sometime soon too. the main holdup i have at the moment is waiting for the latest shipment of wheels to arrive at Otomoto, its not till mid february. Once they've arrived we can finalise the amount of work needed on the guards. once the basic prep has been done she can go off and be caged up, then it all gets cracking from there

Can i ask where you got the Wilwood pedals/masters from and how much?

I would love a set for my car...but looks like a lot of work to get them to fit nicely

I got them through Peter Hall at Autosport here in adelaide http://www.autosportdirect.com.au. All up with master cylinders and the bias adjuster it was a bit over 1100 bucks

[ST1LO]

you have too much money Mr T. where is the latest update?

[Matty 31]

lol, no brendan, the bank has too much money available to me. Latest update - nothing lol. Gavin and I are heading out today to swap my diff (much to my fabricator's disgust as he hates pushing my car around with the locker in) plus we thought it was worth chuckin the k frame and the ISCs in

[Mandingo]

Nice work mate waiting patiently for updates

Can you tell us about the custom K-Frame please?

Cheers.

Dale

[Matty 31]

Flipmo, all i know this far about the custom K frame is it was modified off the original R31 item, but has been made to suit an S13 power steering rack. It also for some reason sits the engine about an inch further forward, which seems rather odd to me. will hunt some pics out later on

[OKBANANA]
