They lock them so no one can see their tunes, they did the same thing to my FC and Scott was able to get around it I would have expected more down low then that, you need to get someone else to tune

Nah I haven't that's why I commented that I prefer a setup to not be responsive.

So how can you say you prefer one if you havent driven the other?

Maybe buy a rb20 and put a gt45 on it if your serious about it.

This is what makes it hard for me to comment, I have driven one with a big single, smaller single and a 3.2. BUT I want to drive a standard R34GTR and the next time I go to Sydney I am going to find a car yard that has one and go for a drive in it.

Don't do it Pete.

After my 4th or 5th variation to my fuel system I've finally come full circle back to twin in tank 044's. Its a mission to get them in there, but worth the effort.

Concealed, no mess, no fuss.

No in car fuel smell.

The only other practical option is to go with a custom under spare wheel setup with external pumps, and the standard pump as the lift/filler pump.

In boot surge tanks take up space, leak vapour, and just get in the way. Technically not legal either, as the firewall is not 100% sealed between the driver compartment and the boot like it is with the engine compartment.

Thats a worry, I thought that it is the most common setup. A continuous fuel smell would drive me nuts.

I would have thought if they are done properly there would be no fuel smell unless there was a leak of some sort :(

A few thousand dollars in Teflon lines and AN fittings with bulk heads will fix a fuel smell, but it still looks messy, and like a octopus mating with the boot of your car.

Then there is the pump noise and power consumption. So then you have to plan to add an alternator too. It never ends.

Really when you consider it, there is no good place to put a surge tank in the boot of an R34. Jack left side, attessa reservoir on the right. Under the parcel shelf is full of electronics and a battery.

044's or the smaller walbro style pumps are really the only good in tank option. You cant run the turbine pumps because they don't self prime.

The R34 has an in-tank antisurge system with a deep pickup location, and a syphon from the left side of the car that ensures the right side of the tank is always holding more fuel. It makes sense to use what is already a good design.

      From Japan and back to Europe, my sh*tbox R34 GTT

      By GoHashiriya · Posted

      Yeah, I get that. I try to be as cost-efficient as possible with cars, and typically prefer to buy them at the bottom of their depreciation curve. I was looking at those Bilsteins too as they're roughly in the same price bracket as the BC's - lack of adjustability and being soft put me off, not that I want anything too hard. That's my issue with the Skyline, it's too expensive and it's reflected in my driving. I don't mind going full pelt as long as there's a gravel trap to catch me. Really, proper safety equipment is needed for total confidence. Well this just turned up for the BMW. I'll try and get the front together tomorrow and take some pics of the absolutely horrid rear end; perhaps I'll have a crack at the rear on Wednesday. I need to make the car drivable before the weekend as I'll be driving it over to London.

      R32 GTST - 600KW+ RB28/CD009 Build

      While going through data logs late last week, I spotted a small issue with my WMI. My WMI starts to progressively inject at 11psi of boost. I'm using a 25psi cut in pressure switch on my WMI as an added safety and if the curve is linear, I should hit that 25psi on my WMI system around 13-14psi of boost.  As per my data logs, my WMI pressure switch only activates around 19psi of boost. This is causing my non WMI 4D map to trim for WMI. I'm presuming this is caused by the mechanical switch response time, injection curve not being linear or both.  I ordered a 2-10psi adjustable cut in pressure switch which should correct this. If this doesn't resolve it before my dyno appointment on Friday, I'll just remove the pressure switch temporarily and more than likely replace it with a pressure transmitter afterwards.    BTW Speedtek has yet to refund me.
