Targa Tas Prepping R32 Gtr

[paulR32gtr]

Ok - be nice - I have nfi about the rules etc - and this is just preliminary scratchings.

A mate of mine has just imported a plain old '89 R32 GTR and intends on race prepping it for, ultimately, entering targa tas for a bit of fun - and yes he has the cash and the need for speed to do it...

Now there are production and modified classes I believe...

I guess the question is - what is within the rules to prep it to sit in the production class?

We are hoping to be able to:

- Fix brakes - AP racing or similar I guess

- Power up - is changing over to N1 turbos within the rules or do you need to start off with an N1? Power FC / remaps?

- Oiling - larger sump / baffles, cooler and restrictors etc to keep pressure down?

- etc etc etc

Now there's probably a rule book that explains all this, but where is the fun in that

[sav man]

You can enter the car in N1 spec, that allowes you N1 turbos, and a N1 oil cooler, and other n1 bits.

The entire braking system is free, just has to fit under the wheels (n1 can run 17x8 std, or 17x9, 18x9 under the option rule).

all ecu's in the car are free, but all sensors must be standard (we run a pfc in our car).

You are allwed to put baffle's the sump, not sure about restrictors.

rule book is here:

GT-R falls under M2

And here's the full regs for you.

Modern regs start on page 27.

We didn't put restictors in ours.... couldn't find a ruling, and found we didn't need them anyways.

I found it wasn't the obvious stuff, its all the little things that add up.

If you want to race an 89 gtr you have to be ready to change all of the wear items....

replace every bush front and rear

steering rack ends (front and rear as well)

radiator was clogged

diff needed a rebuild

tailshaft needed new centre bearing (wallet still hurts over that one....cost twice what a brand new 1 peice tailshaft would have).

freshen up engine (new bearings, rings, valve stem seals, exhaust valve guides, oil pump, water pump)

and you need to upgrade

oil cooler (thanks nissan )

power steer cooler (likewise)

brake lines

calipers

discs

pads (all front and rear of course)

shocks

springs

turbos (well you could run standard but ceramic wheels + extra boost are a bad mix)

ecu

sump baffles (extended sump not allowed)

roll cage

seats

harnesses

extinguishers

tow hooks

terratrip and terraphone

wheels

semi slicks

buper vents for intercooler

brake ducts

silicon cooler pipes with big clamps that dont blow off.

catch can

oil restrictors, external oil return not sure of their legality - its not mentioned so probably not legal

Its brilliant fun, I loved it despite our challenges. Just don't go into it without enough budget it will just be frustrating

[sav man]

you forgot the most importand one. A plastic Godzilla figurine to put in the car.

[paulR32gtr]

Duly noted Ben!

I guess the clutch is an important one too - what have you all found has gone the distance?

[PHaT MR30]

So to run N1 spec on a non N1 car you don't have to run genuine nissan oil coolers and all that crap?

[Marlin]

The way I read the rules, if you enter the car as an N1, it must have all genuine N1 parts, oil cooler etc....

Reading Duncan's list through is one reason Jason and I chose to build a 34 (The blue one). We originally did all the costings and figured to get a 32 up to a reliable spec and rebuild everything, the cost of a 34 with low klms was virtually the same.

Nonetheless, welcome aboard Paul There's plenty of GTR gurus on this forum mate, lots of guys with real-world racing experience, and most are more than willing to help. Build the car strong so it gets through the six days of flogging, and you'll be hooked for life, I warn you now

I guess the clutch is an important one too - what have you all found has gone the distance?

Just a tough single plate will do the job without fuss (std flywheel must remain). If you're anything like us there'll be plenty of clutch stabbing out of slower corners to get the big girl moving

[sav man]

we have a exidy sports ceramic in our car

[t01-100]

I ran an Xtreme XtraHD single plate in mine.

A numberof other GTRs run them. Good for 80 or so 7000-8000 launches at about $900 I think they sell for.

[Duncan]

lol godzilla is still dizzy from the rolls down the hill.

[a20089]

OK looked at the rules and I sure don't want to put a roll cage in the car at this point in time.

There's a non competative part where you can drive "non preped" cars, what is that all about?

[Marlin]

Thats the "tour". Non competetive, following a group leader, not exceeding 100 klm/h I think? You also don't do all the stages because you wouldn't have the time to complete them all at the slower pace.

BUT, you can use all the road. Give you a good taste for the full competition I'd say

[sav man]

I did the tour in 03, you can't go over the posted speed limit, and the tour leaders don't push real hard. It is litliray a tour round the state, I think the tour now goes to nice places to wine and dine for lunch now?

[t01-100]

as my car was a pretty nice example and i decided to put a bolt in removable cage in it... we even reinstalled the whole interior without cutting trim.

the guy that bought my old car who lives in melbourne has now pulled that cage out and is selling it (asking $1500 neg).

it was one of the best bolt-ins i'd seen with welded diagonal and harness bar in centre hoop with solid side intrusion... might be something to consider... i think you would be frustrated driving a GTR in the tour.

[bloodzkull]

i know i would get frustrated as hell doing a tour by the sounds of it.

wonder how pissed off the tour operator would be when he gets overtaken by a gtr

[sav man]

been there, you get kicked out. We got warned that we would be kicked out if we didn't behave (almost passed leader 3-4 times, went sidways up the street in longford...)

[Duncan]

longford was my favourite stage. i'm a simple bloke deep down and there is nothing like sliding a gtr with stuffed attessa up a street in a small town. shame the cameras weren't on
