Fuel system: Siemens 60lb injectors, Holley Dominator 1400 twin billet pump from surge tank in boot, fed from stock tank and pump, Turbosmart FPR 2000 regulator after Holley rails.

Power: 481rwhp with VERY conservative tune on 8psi. 98 pump. 26×8.5×15 slicks whilst on dyno also…

plenty more to push out of it, trying to see what breaks after not being used for a while. so far had the clutch slave and sump gasket. work out the kinks and wind the power on…

 

best 1/4 mile so far has been 11.994 @ 126.7mph with crappy 1.9 60′.

2 step should help lower times and add consistency when it comes.

What block are you using?

So sump gasket is leaking, only slightly from rear, or it is rear main seal, either way I’m not keen on doing it!

 

any tips for doing it the easy way? Or is it just an arse of a job…

[cava454Moderator 93 VR BT1 View build HERE Member since: February 20, 2015 Posts: 2 390]

Either box or motor is coming out….

[GRNMCHNParticipant Alice Springs\'03 VY SS 408ci turbo View build HERE Member since: April 8, 2015 Posts: 26]

Box is a fair sight easier than motor lol.

Pull the gearbox out and sell it off whilst you’re at it.

 

Seriously get a glide or t400. My first time racing with the turbo setup, I didn’t build any boost on the line. Just put my foot down and it went, 11.4@127mph with a 1.9s 60′  on only 10psi of boost.

Did the exact same run twice. So consistency is there with an auto also.

The difference between auto to manual is huge. Also get a transbrake and if you don’t break anything, you’ll be running low 10s easy.

 

A WH Statesmen from S.A ran 10.6@126mph with a standard cube ls1 with GT42 turbo and a 4 speed auto. He was building boost whilst on the line using the handbrake.

I actually rather the manual. I know i’ll prob get better times etc with an auto but I don’t want to put an auto in it, at least not anytime soon anyway.

I really enjoy  driving a manual car so for me it makes it more fun.

and its still only on a run in tune basically so I am nowhere near the times it could run yet, as it isn’t caged yet either.

the wedding and honeymoon are killing the car budget so keeping it sedate and safe for a while till I can get some more bits and charge along.

although the 2 step will be here shortly so that will help with times and consistency

[GRNMCHNParticipant Alice Springs\'03 VY SS 408ci turbo View build HERE Member since: April 8, 2015 Posts: 26]

so I decided to get under the car and clean it up abit, then started to see where the leak might be actually coming from. now no leaks???

I tightened up the sump bolts a little so they may have just been under torqued to start with.

hope its all ok for the next race meeting on 17th may

[GRNMCHNParticipant Alice Springs\'03 VY SS 408ci turbo View build HERE Member since: April 8, 2015 Posts: 26]

So ran at the strip again.

 

managed to run 11.75 @ 126mph.

had a few 127mph passes also.

 

looks like I might need a new clutch now, then start tuning it a little to get some more power.

 

fun times ;)

Don’t leave that clutch too long, I grenaded a Z grip, on my turbo VX, huge amount of carage

You’ll never run the times the car is capable of with a manual, which can be a bit frustrating, and the more power you wind into it the harder it gets to drive.

I’m nearly ready to ditch my M6 in favour of a 4l80e, but still enjoy a fang with the manual

[cava454Moderator 93 VR BT1 View build HERE Member since: February 20, 2015 Posts: 2 390]

Stalled auto will be the best move u ever make. Slap a glide in it and never look back.

[SLAUTRParticipant QLDvl calais View build HERE Member since: March 1, 2015 Posts: 24]

Where did you buy the turbo from  or who sells them in aus ?

[GRNMCHNParticipant Alice Springs\'03 VY SS 408ci turbo View build HERE Member since: April 8, 2015 Posts: 26]

I’d like to go an auto one day but I just wouldn’t enjoy it as much.

did a little driveway skid in 2nd gear and it still grips but doesn’t like to change and moves when going into gear :/

 

bought the the turbo from GCG.com.au

They had them cheap when I bought it then upped the price by a few hundred $

Be gentle with that Z Grip until it’s replaced, when mine let go it destroyed the bell housing as in no bellhousing left – smashed starter, smashed block and sump, broken gearbox bosses, holes in fire wall , smashed inlet manifold, tore through brake lines ( no brakes) damaged wiring loom, blew a tyre out. But I do still have both feet !!!
