I think I've missed something??

A $300 saving isn't much when you put it in perspective with the $3500+p.a you would be spending on fuel. My rough calcs indicate this would offset less than 1% of NSW's petroleum consumption. My big concern is that this is a problem with a time scale of 30-50 years and I don't have the confidence that either the govt or businesses are thinking that far ahead. Politicians think in three year terms.

If you can argue that a few % decreased economy is negligible, then you can argue that a few % lower c/l is also negligible. And therefore the argument that it's cheaper at the pump is null. Hell i'd say even a 10c/l decrease is really SFA, that's what, a whole $6/tank. I've yet to see anyone show me that ethanol or any other biofuel will provide a significant long term solution. I want someone to put together a sound systems analysis that considers the size of the problem and the size and impact of the solution. Instead everyone seems to be focussing on trivial crap such as fuel line damage and saving 5c/l. The "but it can be made from a waste product argument" doesn't sit well with me either. Please show me some calcs that outline the quantity of waste product that we have, the volume of fuel that could be obtained and then put this in perspective with the total amount of fuel required. Waste products are waste products for a reason.

MRT's comments: http://www.mrtrally.com.au/forums/topic.as...511&whichpage=1

Actually reading the response from MRT, I'd say this report isn't worth a pinch of the proverbial.

ok, my guess was pretty close then!

Overall I think the quality of the report is pretty poor. It looks to me like it's a draft that hasn't yet been scrutinised by the academics that should have been overseeing the testing. eg If I was UNSW i'd be dissapointed that something like this was released. If I was MRT and they were asked to pay for this I'd be suitably unimpressed as well. I'd even go further than what Siliya suggests and include ADR drive cycle testing.

Can you find the link?

Ethanol isn't the solution to fuel problems. 1. Where do we get the feedstock from? Raping the farming land? I did some rough calcs to illustrate the amount of feedstock that would be required. To substitute only NSW's petroleum products with ethanol would consume all of the Austs sugar cane crop and half our wheat crop. 2. Given the above. Ethanol blends are just a stop gap solution that's generating a lot of media hype. It might buy us some time, but I don't see the point in spending too much time developing the technology if it's ultimately going to be a failure. 3. The engine damage issue is just a small tech problem compared with points 1 and 2. 4. Ethanol has a lot less energy content than petrol. So your fuel consumption goes up and you either refuel twice as often or have to carry twice and much fuel with you. 5. The price cuts they are talking about (ie a few c/l) are pretty much neutralised by the increased fuel consumption. So you're not much better off overall. 6. Don't quote Brazil as a great example of ethanols success. Their farming techniques aren't exactly sustainable.

Nope. It's just a little cylindrical switch, up high on the drivers side of the box.

What exactly is your point?

Mate I'm up in Newcastle so I obviously can't call round in person. The neutral switch is a cigarette lighter sized bit that simply screws out of the side of the box. Would you be able to post it up to me. Obviosly I'll pay post.

I thought these were about the same strength as the RB25 box but just more expensive and harder to find??

I thought the gtr box was generally a few hundred cheaper? Otherwise I tend to agree.

You can fit any gearbox if you have enough time and money.... I'd think RB25 is going to have the best combination of strength, cost & ease of conversion. I've seen another guy convert a GTR box to RWD to save a few bucks, but the comment was something like if you can't do the fabrication work yourself then it's not worth it compared to the RB25 box

ACL sell a limited range of forged pistons, AFAIK they are made by Ross and rebranded.

Looks very similar to the 2nd pic I posted up. 1,2 and 5,6 are just swapped where they enter the collector.

Negotiable?

So tonkau, you've been awefully quiet, whats the latest? Any response to the clearance questions posed by SK and proengines?

From all reports I believe the 6boost stuff is up there quality wise and probably performance wise with the Jap stuff. But you are better off to get in touch with 6boost himself and make your own mind up. Unless you are specifically after a brand name and the bragging rights that go with it, I don't see why you wouldn't consider a good local product. His collector design certainly appear to be unique.

Maybe also check out this guy out, cost around the $1000 mark. I've only heard good things so far, so he must be doing something right. http://www.calaisturbo.com.au/showthread.php?t=50987 Some pics for those who couldn't be bothered opening up the other thread:

A quick look at ACL's web site suggests their standard range of "Race Series" pistons, which have been around for yonks, aren't forged. ACL never suggests they are. The warranty for these pistons specifically says they are not for forced induction applications. ACL do have a newer range of "Race Series Hyperlite" forged pistons, which I think came out earlier this year (made by Mahale IIRC?). There is basically no literature on these. Since some of these pistons are specifically produced for turbo engines (BA turbo, Skylines etc), I cannot see how the standard "Race Series" warranty can apply. So what Retrotec is saying seems correct, however I think it's not really relevant here because tonkau's problems seems to be with this newer series of "Hyperlite" forged pistons, which are a different beast altogether.

We're not allowed to pay out on businesses. Read the forum rules mate. The lawyers f ucked true freedom of speech. Care to share? So far you have only told us about the damage. You don't appear to have given any reason other than 'faulty pistons'. What particular aspect of the piston is responsible for the damage?

First thing i'm gonna say is that I don't think this thread will last long. Second thing, I don't think your approach to the problem does much other than aggrevate ACL, who probably just see you as another whinging customer who f ucked up when using their product. Rather than theorising that "it's ACL's fault because we couldn't have done anything wrong", why don't you actually determine the root cause of the problem? Is it only one cylinder or all of them?
