[url][/url]Anyone going to Challenge Bathurst Event?

http://www.challengebathurst.com/

Nuffy (ex GTI track car guy now S15) and I (skyline) are going for a fang around in the regularity class.

6 x 20min sessions. Rules are we've got to stay under 2min36sec otherwise we get black flagged.


I heard the GT cars will be there practicing on Thursday and Friday. Tilton Evo will be there going for the outright lap record.

Had a shocker of a weekend.

Saturday
1st lap broke diff. then drove back to sydney to get new one. Got new diff in by 9pm that night.

Sunday
About 10 times per lap the car would turn off for a fraction of a second and then go again. Very frustrating.
2 sessions - Black flagged for going under 2.36,

last session car stopped on top of the mountain. Discovered a week later the fuel pump relay wire screw on the toggle switch was loose.

My best was 2.31.55, (with a 4.1 new diff in lieu of 3.6) and car kept turning off!

Plan to go back next year and enter the supersprint (no time limit). Should be good for mid to low 2.20's.

One funny thing that happenend.
I was going down conrod at about 240km/hr and something hit the windscreen, due to speed i couldnt see what it was but thought to myself "was that my grill".

Looked in the rearview mirror and the thing clouted the car behind me fair in the front.

I forgot all about it untill a week later and checked it. It was gone (now in a 1000 pieces somewhere on conrod). The clips were still in but the plastic brackets were sheared and ripped apart.

Heres some footage of a GT3 Ferrari 458 car that gave a short back and sides going up mountain straight.

Went to challenge bathurst in the supersprint in the skyline a week ago.

Did a 2.23.56.

Flat around the chase at 252kmh was fun and 180kmph around skyline bend.

Car was faultless and didn't put a spanner on it for2 days.

Race engineer was good showing me where i could make up time. Up mountain straight car was walking past porsche gt3's.

Surprised there are not more LS1-3 conversions

I was watching an episode of Overhaulin. They were doing an old school yank tank

Walked into specialist supplier & picked up LS3 crate engine. absolutely complete ready to drop in & turn the key

Your speed machine & Beau & Tony Hattons BMW in Qld are proof of this strategy

I agree. You can buy conversion kits like you describe off the internet.

Ive got a whole new outlook on these engines. I rate these engines highly.

Ls conversion is quite a simple and cost effective setup. At the end of it the car will be punching out some pretty good lap times and not have changed the characteristics of the car too much. Due to its relatively light weight alloy engine.

Gm in usa spent sqillions on dollars making these engines what they are. They are not "old school" by any means.

I did a lot of research before i launched into the new setup. Engine wise it was really simple. Crate motor came with everything, coil packs, leads, throttle body, headers, alternator, water pump... my engine brand new was $7000 off ebay. Came from a car dealer in Brisbane in a cardboard box stamped holden S.A.?

I went motec but a really good buy is the Holley Dominator ecu. Its plug and play. It is well priced with wiring harness. Basically connect to battery and go. Can even get accel pedal with it. Fly by wire.

There is no possibility of running a turbo setup making 432hp atw for the same budget, reliability and drivability.

One thing this engine does need is a dry sump. These can be had pretty cheap via kavanagh auto in melb.

The old adage

There is no substitute for capacity & with these new light weight engines No giant weight causing understeer like some of the old cast iron engines

I think you could fit one in the back of a GTi
