^^^^^ What he said! The PFC base map is intended to err on the safe side, but even they can't guarantee you won't hurt your engine.

Is there a more recent version than .54 available? I've had a peek and see that I can't just copy maps from the software to Excel. Not sure about back.... Please send me a link to the latest if you can. Cheers, Dan

Hello, My PFC map is 100% self tuned, but I read Paul's FAQ before I started. Will Paul be pissed at me if I share my map? I can send you my map, but I should confirm you're looking for an RB26 map. (Thread title refers to GTR, but your profile lists RB20...) Take seriously the cautions to make sure the tune is right for YOUR car. I had mine running just like I wanted, and then one day it started running rich across the board. Boost leak should make it run rich on boost, but either the same or lean on vacuum. Not that.... My guess is that my fuel pressure regulator is dodgy. I've ordered a fresh Nismo adjustable one and will re-tune. Anyhow, PM me if you want a look at what I'm running. Cheers, Dan

I understand that the Skyline transfer case is not intended to send torque to the front for more than 12 to 18 seconds at a time. This is not a rally car like the WRX, but a track car. (If you break traction for more than 15 seconds you've got other issues!) The multiplate wet clutch controlled by the ATTESA computer generates heat and will damage itself if it's working all the time. Cheers, Dan

Scott, Beautiful car. I'd look seriously at importing it to Canada if I didn't already have GTR I like. Providing it fits Canada's 15 yr rule, (Car is a '91 model or older) you might want to advertise it on www.gtrcanada.com. Quite a few people are selling GTRs here and it's a bit of buyers market, but your car looks to be a cut above almost anything I've seen in Canada. Our dollar is pretty strong right now, so even with shipping it could be considered affordable here. I'm sending a link to a mate who's looking for the 'perfect' GTR. Cheers, Dan

Great thread! I found it while searching for typical pressure and temperature drops across stock RB26DETT turbos. My motivation is to nail down some 'safe' EGT's measured in the downpipe. I know many prefer to measure at the exhaust manifold because the measurement is more direct and therefore immediately meaningful. In general, I know that work done by the turbo is related directly to pressure and temperature drop across the exhaust turbine. Therefore, I expect bigger temperature drops under full boost than I would just cruising down the highway. Ideally, I'd like to calculate the turbo inlet temperature based on boost, mass air flow, and turbo outlet temperature. The only variable I'm missing is pressure drop across the turbo. Has anyone measured this? Cheers, Dan

If you flow test the 6 you're going to run and fit the PFC, you can adjust the relative flow of each injector based on the test results. Install the PFC man!

I've heard you can expect 10-15 hp more from an RB26DETT. Not sure how the stock fans compare between this and the RB20, but I'll bet you'd realize a gain.
