Oh man, first time someone has given me a proper forum insult "umad"... brilliant; cheers for the quote though champ.

Thanks Brad was waiting for you to chime in... oh and mate can you email me still keen for that sump!!!!! Getting drawing of my custom designed pump, will send through details for your interest.

Was the reason the Japanese GT cars went with RWD platform for their GTR's to do with rules or for the reliability, weight improvements?

I am approaching this from the opposite direction R33 GTS-T to GTR running gear.

At this point I have a GTR dash, seats and trim installed.

I am currently building a full GTR cradle and diff to drop in with Bilstein PSS9 shocks for the December track day.

I have modified GTR Bilstein PSS9's to fit the GTS-T front suspension and retain the correct ride height and adjustability.

I also have all of the GTR additional braces for the floor, behind the motor and inside the boot to stiffen up the chassis.

Next on the list is a full set of GTR Brembo brakes to complete the running gear.

If I really start to get serious I also have a full GTR front (guards, bonnet, front bar, reo, grille etc) that I had painted to match the car when it was resprayed packed away in the shed.

I hope to have the handling and performance of a GTR, with the running costs of a GTS-T and lap times somewhere between the two.

japanese GT cars have set specifications, like pretty much every other racing category. that is why some of the GTRs were rwd. it is also the same reason the R35 GTR's run in rwd and are powered by a 3.4L V8

^yup

R32 GTR's were always run in awd and spanked everything which is why the series moved to rwd, to even out the playing field. I'd say though that the spanking at the time of the 32's was more to do with the fact that the cars were so far advanced in all aspects compared to the rest of the field, and not just cause they had awd.

It's actually pretty intersting though that most categories make awd cars convert to rwd to even things up?? Maybe your answer is right there :)

fyp :)

R32's raced under group A regulations nothing even remotely similar to the current GT categories.......

What current categories (defining most not just one or two) actually require RWD converted cars.

NASCAR makes Toyota turn a camry from FWD to RWD and run a copy of the Yates 357 Windsor lol ;)

Been here done most of that......

My old R32 GTR which was raced not just tracked had a terrible issue smashing front diffs off the grid.

I'd get the first race down and the rest of the weekend would be spent with a crownwheel floating around in the front diff.

The car would be very difficult to drive when the front diff would first let go. After some chassis work to make livable I would end up leaving the front diff broken for the rest of the weekends

Nothing else would change just no front diff.

Perfect example of why brad should keep using front diff's :P

Obviously not categories for us here, but the ones i was thinking of - GT1, Super GT, JGTC (not sure 33's, but 34's were rwd) DTM, Sport Sedans (i think)

seen that launch allot better, that gtr won powercruise of street drag racing not to long ago, also does mad 4 wheel hellis

I've actually launched that car alot better I'd agree.

As for winning some drag race I doubt it. The car was retired after that race meeting and hasn't turned a wheel since.

Infact I built the car and it never even seen a drag strip during my ownership.

4wd hellis from that car I highly doubt too, it ran a 330 slick front and rear that cost more than most peoples rims and tires put together.

Diff explosions were more caused by the transfer case experiments.

We could make a diff survive during qualifying due to the rolling starts, the shock loading put onto the tiny diff from the transfer was doing the damage. The failures were almost always stripped crown wheel teeth.

It didn't matter if the car had small AO48's or dunlop's michellins etc you had to slowly feed the power to the front from a standing start.

Factory transfer case problem fixed but car slower.....

It seems that a GTR in rwd form, purpose built that way would more then likely be better then a straight gtst. Purely due to the car having a better all round setup from factory. Slightly wider track, provision to run bigger wheels/tires which is quite important. This is severely limiting in a gtst. The most obvious one being the stance of the gtr makes it looks a hell of alot tougher then a gtst!

But in the end, if you have enough money you can make any car quick or quicker then your competitors, then you just need the skill to drive it. So eitherway is achieveable, Comes down more so to whats going to give more benefits for the least amount spent on it.

That is what I am thinking Mike.

It is a lot of weight and cost (from an initial stand point and also ongoing maintenance) to remove the front diff and transfer case and all associated components. Will make the dry sump pan easy too.

Also, instead of spending $10k on a PPG dog box you could spend a touch more and get yourself a refreshed used Holinger.

You know "guys like us" dont have enough money to make any car quicker than competitors :)

you would have to weigh up...whether it is worth buying a GTR for over 20k prob 25k then spending all the coin working on it to be rwd.

or buy a 33 gtst for 4k, with a cage say 7k, GTR front guards for a few hundred, fiberglass rear guards, chuck a RB25/30 in it + your hollinger

and you have a car that will be so close to what you want to do you would have to be Michael Shumacher to tell the difference is chassis rigidity

and it wouldnt cost much more than buying a Standard 33 R to begin with. then spend the 20k saved on not buying a GTR on some of Brads trick suspension bits and a dry sump setup.

its what I would do given the coin

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
