I'm really curious to see a datalog of the 6sp being driven in anger. I fear/suspect there's throttle closure fuckery as a self-preservation measure. Should be addressable via a real tune, but that is the JB4 downfall in my experience.
Nice. Good move on building the block. What all are you having done the head? Honestly the TQ number makes me wince a bit. I've had the dubious owner of windowing a stock 2J block back in the day and it was not a happy ending, to say the least...
I think the vast majority of us OG stick shift drag racers would rather bang gears in a 10 sec car than hold the wheel straight in an 8 sec car. You either get it or you don't; most don't and that is fine.
The G30 is a baby dick turbo best suited for 2.xL 4cyl or as a pair of twins on a smallish V8. The 55mm turbine exd is a terrible combo and smells like a recipe for compressor surge. You might as well save the cost and complexity and drop the 'cool factor' of a kit and just go Pure 850...
I'd go with the G35-1050 all day every day. The G30 has a teeny tiny turbine. Great for spool/initial response but it's going to be a tire fryer and out of breath quickly on our modern and efficient 3.0L. The G35 will be right in the meat of its efficiency at your goals and will have plenty...
Could being the operative word. You could also make the car fly with enough effort.
No one TMK is working on a standalone Motec firmware, harness, etc.. for this platform. The current and pending Motec offerings are all still piggybacks.
I'm averaging ~7 MPG on the road course. :beer:
That aside, mileage during regular driving is phenomenal -- better than all of my other cars by an order of magnitude. I was still getting ~30 with the E40 mix. Too bad I don't GAF.. ?
No major issues but some annoyances.. The wind buffeting is the most notable but several aftermarket options available. Interior rattles seem pretty common and I have two intermittent - drivers side door panel and the passenger seat when not occupied. The 2021 oil consumption thing is wayyy...
There was a blue M3 at the track last weekend that was absolutely stunning. I got excited thinking it was Portimao but after some googling it was San Marino. ?
Here's a good comparison: https://g20.bimmerpost.com/forums/showthread.php?t=1584363
This is where I am. Still debating which to go with (and availability can be an issue).
The stock tires did ok for me the first time out. I just did 2 days this past weekend and even with a slightly more aggressive alignment after the first few sessions I lost a significant amount of grip...
