Thanks for the response. New Magnaflows are in. Will try the Temp sender.

I'm looking for some help with regards to EFI and exhaust systems. I put the GTS in for her MOT (UK annual government test) the other day and all was well until the emissions test. Everything is fine apart from the CO reading. It's averaging about 1.2 rather than the limit of 0.2! The oxygen...

I've got a series one VT GTS and that is a 5.7 Holden engine. They were stroked by HSV using a Harrop crank. I have the 6 speed manual bolted up and it's fantastic. The clutch can be expensive as they are different to the 5.0 and the gen 3 Chev 5.7 and HSV didn't make many stroked 5.7 cars...

Yeah, thanks man, that would be a good start. Just email me if you like. [email protected] Cheers!

Thanks for the reply

I know I'm bound to be warned off these but still. I need a wiring diagram for a vt 5.0 and unichip D4 please!!! I have the chip and somewhere to tune it but no diagram. APS were less than helpful. I want to go the Kalmaker route but living this many thousand miles from Aus makes that...

MWS in in York, Western Aus. Turbo is just too much work mate. There are only six VT GTS cars in the whole of the UK so it needs to be a fairly straight forward setup. The stage 4 kit is 14PSI intercooled positive displacement charger etc etc. Thanks Also, Kalmaker is unheard of...

Has anybody dealt with him or know anybody that has dealt with him before? From what I can tell, he is awesome but I'd just like a few impartial views. I like the sound of a stage 4 SC kit for my GTS!:w00t:

I've got a VT1 GTS 355 stroker and am looking at S/C kits at the moment. I like the look of the Vortech kit from CAPA at $7995 for 340kW. I've got HM headers, high flow cats and twin 2.5" cat back fitted. If I fit the Vortech, how many extra kW do you think the exhaust system will give me...

Cant find them on google aus. Have you got a web address?

No I haven't but I will now, thanks. I'm gonna discuss options with MWS I think too, they are v. good by all accounts. Have you had any dealings with them?

Don't get me wrong, the AVS is great in the dry but just a hint of moisture and they let go. Even with the traction control on. Maybe I expected more for my money. Tyres here are ridiculously expensive for anything decent. The roads are shocking, and it's wet more often than not so will...

Maybe the tyres are different in the UK. I have the 18" Yokohama AVS Sport. £140 a corner here (about Aus $350) I bought them thinking you get what you pay for but no way, they really are useless in the wet. Toyos, Goodyear or Bridgestone are the best for your money.

:bang: Does anybody have a blower manifold for an injected 304? I want to run a Whipple on the GTS but can't find a manifold anywhere.

I want to put headers on my 355 stroker. Has anybody got HM headers or had them in the past? How do they stack up against Pacemaker and the like? Any other suggestions? The HMs look good and seem to be well priced.

I've got Yokos on my GTS at the moment and I'd NEVER buy them again. Not bad in the dry but if you even so much as think about a bit of right boot in the wet you'll be all over the place. Absolute d0gsh1t. leave Yokos well alone.

I thought as much. Thanks for the help.:thumbsup:

What do I need? Is it even possible? Any advise would be great guys. Thanks.

Not the right one but thanks for trying.:thumbsup:

:bang: Can anybody help me??? I'm looking for a copy of the wiring diagram for a Dastek unichip model D4. I wanted to take the Kalmaker route but cant get my car tuned anywhere as I'm in the UK. I bought a 2nd hand unichip cheap with the wiring harness but it has no diagram and APS in Aus...

A mate of mine had a similar problem. Turned out to be a vacuum leak at the inlet manifold to the head above the problem cylinder. Just a thought.:bang:

Steering/ suspension bushes perhaps? Would be very suprised if it was the trans.

:mad: Possible knackered cv joint on the driveshaft. May be worn or broken bearing race inside the joint. Not a big deal if that's what it is. Part shouldn't be too much and relatively easy to change.

Starr performance manifold,TB and MAF. Are these worth the money or not? Has anybody on here got this setup? What are the power gains etc like? I have looked at the Twin TB and Manifolds from come etc but they are just too much money for what I'm willing to spend. They will be going on...

Does anybody know if that can be done or has been done? Could the gen 3 flywheel and clutch setup be transplanted into my iron block Holden? Already have a T56 fitted so there should be no problems with the input shaft. Just potential balance problems and the VT1 GTS had a pull type clutch. Can...
