Well it's there for a reason, but personally I think the chassis brace is more important...

A drum of ethanol and more boost.

I have a centre viscous here you can buy Leroy.

Are there seriously no L19 or 625+ options? The spring tension of the standard ARP studs isn't much better than the stock bolts is it?

Think about it. If you are running decent boost, then 99% of the time the wastegate is closed, which means the turbo has a 3 or 3.5 inch dump to get rid of the exhaust flow. Only when the gate opens does it add to that flow. Most split pipes do restrict, as the turbo pipe is only 2 1/4 or 2 1/2 instead of 3 or 3 1/2. I can nearly guarantee upgrading to a decent bellmouth will improve response, just due to the increase in pipe size available to the turbo. Realistically at 300kw you want a 3.5 inch dump at least, this can be tapered back to 3 inch after the cat as the exhaust gas has contracted as it cools, and it cools fast. The dump isn't the place to restrict the exhaust, here bigger is best.

Seen it too many times to mention. The more boost you run the less runner size you want imo, so a little bowl work is fine, and I agree with port matching, but I would like to actually add material to the port to increase the gas speed before the valve. Just think how long the valve is open for at 8000 revs, and what speed the air needs to be going to fill the cylinder in that time...

Dandenong will do it too.

Come around and borrow the lathe mate, a pair of stainless ones wouldn't be hard to knock out I imagine... Do you have a pic of the pin?

Try backing the tension off the aircon belt a little and see how that goes before swapping bits.

Ditch the sidefeed crap and put your topfeed rail in mate, e85 ftw.

A single 460L Walbro in a surge tank will do 460wkw at least, as long as the pressure isn't too high. Try a 35psi base pressure before buying 2 pumps is my suggestion, or get a fuelab or similar turbine PWM pump.

Perhaps a search would have been easier? Yes, the Nissan replacement ones are shite, grab an aftermarket one as I don't sell them anymore.

30psi sounds good Andrew. Why were you trying to fix it? Sounds like there is a leak as I said, causing the idle air control valve to open and close while trying to lower the idle to it's preset revs. If there are no visible leaks, a pressure test may be the best option...

There are no Jap 4 inch systems, you may find a 100mm, but most are 90mm at the back, with plenty of restrictions in between. You are obviously chasing power, so it's best to go for a custom twin 3 into 4 inch system, then drop it to 3.5 for the rear muffler to keep the noise under control.

No boost is the safest option...

Man, those 040's are crap. Just get the 460L and be done. http://scottyscustoms.com.au/product/walbro-e85-400lph-intank/

I got stickers a month or two ago..

I'm confident it's been done many times in Japan, so if you sent them an email and found someone who could understand English, i'm sure they could work out what rail you need. Otherwise ask Jesse Streeter, or Import Monster, either could help i'm sure. There is also a Recaro dealer in Melbourne SE that may know. There are a few types of Bride rails to suit different seats, so you would need the correct type. Bride rails aren't the best, I would prefer Recaro rails.

I get 10L per hundred from e85 in the Evo, on the open road. Pretty good, but I doubt you will get that with the V8.

Don't forget you will need twin SUS power filterz mate for that power.

Sorry Birds, he was in the 86/brz club. Craig Furniss with the BRZ, managed a 1:54 I think.

Not sure, the guy was SAU so it wouldn't be hard to ask... There were two running at PI, and I know at least one was on e85, the one in my group.

That aint det Simon, it's spark breaking down. I had det on e85, but i was running 22:1 on cruise while fiddling. Any plug in ecu would have the same benefits, Haltech do a plug in too.

I try and warn people the PFC is a 20 year old piece of dinosaur tech, and it's worth $20 in the scheme of things. There have been better options for many years but everyone still gags over them. The flex sensor is only $50, but the ecu to control it is expensive. (although at least you can then access it yourself rather than have to pay for the same tuner to access it like the Xcal pos.)

It's been many years since tolerances were that loose to be a problem, this aint the 60's anymore, machining and materials have come a long way, and we are running highly strung turbo cars, not clunky V8 tractors with 1mm piston clearance.
