Just reach out to them, and tell them you’re a returning customer! They don’t advertise there HPFP+injector deal.

Just get any ethanol kit that taps into the BDC. The BM3 kit uses the same continental sensor as any other ECA, but they use an anodized fitting to reduce the 3/8” fuel fitting on the ECA to the factory 5/16”. In other words, you’ll end up just removing the BM3 specific anodize fitting if you...

The cost of the transmission has been my main barrier into wanting to move to next power bracket. I’ve been enjoying the power of the new turbo, but it seems my tuner is constantly fighting the limitation of the HPFP in the midrange. It’s probably worth canning e40 with the stock fuel system for...

if you were to do this again, do you think the HPFP is a worthwhile upgrade for your goals, or would you have just done both the HPFP and injectors to give you more overhead?

Thank you for the reply What is the association between HPFP angle, rail pressure, and rpm? I’ve seen rail pressures drop while the HPFP angle isn’t maxed, and I also see rail pressures increase past target and HPFP angle is several degrees below the max. I’ve been under the impression that if...

I’ve been trying to do more research on this topic about the stock Bosch HDP6 pump found on b58 TU, and was wondering if people can provide insight. I know that the target operating pressure is 350 bar (5000 PSI). I’m under the impression that the HPFP will crash at ~4300 PSI (-700 PSI based on...

I added a BM3 phenolic spacer along with my wagner manifold. I can't quite say if it helped at all, but I can say that it at least didn't hurt. My overall impression is that the differences are negligible. When I track, I'll sometimes take long data logs just to see how IAT's and temps trend...

since you’re not lowering your car, you won’t need to buy adjustable links, although the rear links are plastic. Not exactly a failure point, but I replaced them since I run coilovers. A lot of bolts that you will remove are TTY, so best practice would be to replace them. I tend to not get...

I have a z4 so YMMV. I ran an aFe front sway bar for 6 months and had about 6 track days with it. I only did the front at the time because of how easy it is to install. By itself it definitely improved the front body roll. I run staggered ecs02 275/305 so it did increase understeer, which i...

I took some of razorlab’s advice. I put in a pure850 doing about 23psi of boost as the stock turbo was outside of its efficiency range w/ e50. The charge air temps before the manifold are definitely lower vs stock turbo, and the Wagner seems to be a little less stressed trying to cool it down. I...

Currently working with Doug Newton at Subpar. BM3, Flexfuel multimap tuning, currently working on e40 for a pure850. Sameh took 2 days to reply to initial inquiry, Doug replied same day. Spoke with him a week prior to purchasing a tune. Bought morning of 10/1 and base map was sent within an...

Thank you @razorlab! I’ll send this information to my tuner and refer back to this for anyone else having this issue in the future.

Recently installed a pure 850 which deleted the PCV heater element. As expected from prior research, I got a 16050A “crank case ventilation leakage” code. I double checked all the lines to verify they’re properly connected, and reseated the oil cap just to make sure there are no other outliers...

You can live in your car, but you can’t race a house.

Apex VS-5RS same spec. No issues with clearance. I do have KW DDCs @ stock ride height, but the differences are marginal.

The e brake motors are just held with some hex bolts. Nothing fancy about it, and no coding required. The e brake motors are specific to g20 with m sport/supra/z4 calipers. Other G chassis BMWs have rear brakes manufactured by TRW and are not compatible with the Mando manufactured calipers on...

No, stock lug bolts are fine because you're not changing the distance of the center bore to the wheel hub. Wheel spacers change that distance, so you'd need to run longer bolts then. Apex wheels are also compatible with the stock lug seat style (which I believe is conical).

Might be interested! I’ll be doing Charleston peak the weekend before, so depending on how the car is behaving I’ll be in touch.

Yup! Their Motorsport gold. Looks like champagne in bright daylight and looks more gold as the sun starts to set. I was going to do bronze, but I already have that color scheme on my other z4 ?

Not quite a Supra, but I get compliments wherever I go! VS5RS 19x9.5, 19x11 Supra fitment.
