Duncan Posted June 10, 2006 Author Share Posted June 10, 2006 I had ruled out rotors because they are the only engine that blow up more often than an rb26 Link to comment https://www.sau.com.au/forums/topic/119743-creating-a-dedicated-track-gtr/page/6/#findComment-2244694 Share on other sites More sharing options...

Beer Baron Posted June 16, 2006 Share Posted June 16, 2006 If you could do it cheaply I guess it makes sense... It would be an interesting comparison though. Do it and we'll have a track off in 12 months time somewhere I have the engine figures here at (including transmission) SR20DET 490 lbs / 222kg RB25DET 667 lbs / 302kg You'd have to allow the greater weight of the RB25 box vs the SR20 one (20kg?) in the above to compare the engines themselves. VQ35DE+T in an R32 GTS-T (or an R33) could also be an interesting one?? assuming of course it can be made to fit relatively easily. In a few years when the cost / availability of the engines is a bit more down to earth. sounds good to me. let me finish with my GTR first, then it's SR2032 for the win! 80kg weight saving is not bad at all. hell if you had some dough to spare just build it up as a tomei 2.2 and like I said use GTI-R valve train and the quads (need to adapt to NS mounting though). It would be a very nice track car i reckon.

Laurence Posted July 9, 2006 Share Posted July 9, 2006 Just strip it, get radiator, oil cooler, sump, some proper gauges, suspension and a roll cage and you are done. Then spend the rest of your money on tyres, petrol, oil, brake pads/rotors and every single track day you can get to. Project cars with a million horsepower are great... to poop on!

EfiOz Posted July 15, 2006 Share Posted July 15, 2006 Ok using IPRA regs from memory R32 RWD (min weight can be 90kg lighter) strip interior, seam weld shell 8 point cage with lateral bars at a/b/c pillars and front strut bars. 'Glass front dam with splitter and undertray (push that as far as the rules will go) Polycarbonate windows Everything above the axle centreline either gets mounted onteh floor or turned into plastic/CF/'glass (where applicable) Flat floor with tunnels (I can't find anything to say you can't do it!) Turn P/S from mechanical to electric pump (not as expensive or as hard as it sounds) Here's the bit that'll freak people out RB30 Naturally aspirated with double cam head 12.5:1 CR 50mm ITB's Big cam EFI Euro96 ECU Bosch 044 pumps X2 Aiming for 350-400hp at the flywheel Why? Because then you can run at 1225kg min instead of 1455! Turbo engines have a 1.7 equ factor so a RB30 turbo is a 5.1L (1455kg RWD/1545kgAWD) and even a RB26 is the 4.4 so it falls inteh same weight class. Exedy clutch with light flywheel A Hollinger would be nice but I think that's getting a little too much Suspension custom bars Koni 2812's (if budget allows) Otherwise Koni yellow Eibach springs (I'm guessing 300-500lb) Fiddle with geometry/mounts/bushes Brakes Bias bar Brembo's F&R PFC rotors and pads Quiafe/Torsen LSD Digitek logger with dash and as many sensors as I could afford (shock pots, steer angle, etc) I think I've blown the build budget for the year so far. But then, if you want cheap, buy a Playstation!

You choose a nissan because your a nissan man...who cares if its cost practical or not...I wouldnt care if it cost me three times a porsche to make a gtr just as competitive. It might take me three time longer to do, and complete but hey im loyal Im gonna get a sticker for the back of the 33 racecar.

Roy Posted July 25, 2006 Share Posted July 25, 2006 Funny how they werent banned from Touring Cars, but yeh. Interesting to hear you think its CHEAPER to buy a GT3???? From what i have seen a decent Skyline, bet it GTR or even GTSt will be close if not quicker then GT3 Porsches. A GT3 Cup Car is another thing, much quicker, but still surprised you think its cheaper to buy a 200k ex race car rather then spend 40-50k on a GTR, and im betting the GTR will be as quick as a Cup Car Link to comment https://www.sau.com.au/forums/topic/119743-creating-a-dedicated-track-gtr/page/6/#findComment-2356057 Share on other sites More sharing options...

Roy Posted July 25, 2006 Share Posted July 25, 2006 you can buy a older model GT3 cup car(Track only) with cage and MOTEC for around the 130k-I have spend 100k on a R32 GTR before and it was quick but when it came to cosistant lap times at Qld raceway the Porsche was faster, more reliable and better engineered all day every day(and this was with a well known V8 Supercar driver doing the driving of both car)GTR's are good but by no means the be all and end all- I have had 6 of them but no more How many Porsche in the top 10 at targa this year??? ummm any GTR's???.... And as for being called a trader by num nuts(R33 Racer) i have had 30 plus Nissans over the last 10 years and at least 15 were Skylines and 6 were GTR's Fair enough, but i dare say you have spent money in all the wrong places...as i can seriously spend 50k on a a number of cars and you will be quicker over a number of laps. If you are talking about getting 30 laps out of a set of tyres rather then 25 yeh then maybe. Its all a game in spending the money in the right places.... Ok here is an example... Series 8 RX7, Completely gut the car, put in a full cage, 15k on suspension and wheels, 8k on gearbox and clutch. 25k on engine, fuel system and electrics. 5k on brakes. 5k on ReAmiya Aero parts. The car as a race only import is only 10k. Say another 5k opn race seats and harnesses. I would gladly bet my money on such a car beating a GT3 Cup Car....most definitely wipe the floor with a road GT3. Throw those numbers at any decent platform and you will end up with a quicker car. At the end of the day a Cup Car weighs 1240kg and the engines are sealed GT3 RS engines...so whats that 260rwkws? Those numbers arent that hard to beat with turbo Japanese cars, especially if you are throwing Penske/Ohlins/Proflex shocks etc under them Link to comment https://www.sau.com.au/forums/topic/119743-creating-a-dedicated-track-gtr/page/6/#findComment-2357088 Share on other sites More sharing options...
Beer Baron Posted July 25, 2006 Share Posted July 25, 2006 yes $100K spent on a GTR to be slower than a 996 (or older) GT3 cup car was definately not wise spending...

Roy Posted July 26, 2006 Share Posted July 26, 2006 If you're throwing Ohlins at tehm then you'll need your 15K for the shocks alone. It really depends. Ohlins as a description doesnt really mean much does it. Like anything you have your cheaper Ohlins and you have your pricey top of the range Ohlins, Bilsteins, Proflex, Penske. At the end of the day a Cup Car uses control shocks, so im pretty sure that $2,500-3,000 a corner on supsension , so max 12k all up and 3k on forged 17" wheels is a adequate budget. Suspension arms etc do not have to be anything radical or expensive. Anyway thats my thinking Im tlakign out my a55 anyway so Link to comment https://www.sau.com.au/forums/topic/119743-creating-a-dedicated-track-gtr/page/6/#findComment-2357724 Share on other sites More sharing options...
