I started with a Turbosmart item set @10psi, it dropped a psi in the last 1000rpm which I thought wasn't bad, but then when you go for a quick gear change it would overboost to 13psi for a sec. As my plans were a FMIC,SAFC and 12psi I didn't want the boost to hit 15psi so I got a Profec B, never been happier.

I had a turbosmart bleed "blue type" as my first bleed, this worked ok i spose used to spike to 15 and drop to about 10 psi

I now have a Blitz duel sbc and this is set at 15psi and while it doesnt hold 1 bar it gets to 1 bar quicker and bleeds off slower.

The ebc was almost easier to install then the bleed valve

I'm actually starting to think that i've got a problem with the SBC.

This morning it was on auto mode all fine started to hit 1 bar then I started winding out third and it hit 16psi ?!?!! WTF I thought.

THEN i set to manual mode and set it up right.

First gear 13.6psi.

Second gear 14.7psi

Third gear 15psi.

I'm going to double check everything then get tim @ rpm to check it out then return it if it is dodgy.

I also swear that the EBC does make boost start to come on a little quicker but then it gets up around say 12psi and where with the bleed it would jump to 15psi now it sort of goes up there smoothly. ?!?!

One thing I did notice with the Profec B is with the lo/hi knobs, even if there both set at 12psi, on low I won't get 12psi unless I'm at 100% throttle, but on high I can get 12psi at 40% throttle. It's good for when it rains I guess as you don't have to be shy with the accelerator.

Also with the balance knob you can set boost to drop off, rise or stay the same in the higher rpm.

I must say I have noticed it also.

With EBC's you seem to need more throttle to make more boost where as the bleeds tend to flick up there easier. (Spiking)

I havn't got a balance nob but. I just set the gain lower and it holds boost better up top.

      Mistakes were made, my R34 Story

      (it is a brand new ported mellings pump) I suspect the lack of pressure is due to the leak. It was *not* that low in other logs of oil pressure in the past. It wasn't that hot either, but not far off.

      Would a Mellings oil pump be a viable option  From my time with a LS, and talking to tuners and LS specialists, the "weak" OEM oil pump is one of the first things they recommend to swap out if I was going to give the engine any high RPM I opted for a Mellings high volume, with the high pressure springs and I never had a issue with it Cost wise they are not expensive in the scheme of things

      My new to me M35 Stagea wagon

      By davemoto63 · Posted

      Just bought a 2002 Stagea 250tRS VR-X Four AERO VQ25DET and spent the last two weekends cleaning and detailing it.. still have to do the wheels and the engine bay but the rest of it came up nice. Imported 2011 to S.A. and I'm the third owner since it was imported. I met the guy who brought it over, he went to Japan and picked out the car, bought it and ordered the wheels. He also gave me a list of stuff he did to the car with receipts. Coil overs (I have the original springs), 3" exhaust from the dump pipe back no cat, Custom dump pipe,(I have the original exhaust), Plenum spacer, 18" custom Work XSA wheels (need restoring, I've made a start..), Shift kit put through the 5 speed tiptronic auto, TV and menus/screens changed to english, Australian DTV tuner installed in rear. I've just had four new discs and new pads as well as all the fluids including the brake fluid replaced. I have all the receipts for the last 15 years and the import papers in a nice folder. Car looks great, goes like hell but fuel economy is not a thing lol.. pics next..

      Steps to DIY sanding car back ready for respray....

      By silviaz · Posted

      I ended up in this rut again lol, and used a shit ton of filler. One thing I can't understand is, even after using a big long block and going in long X pattern strokes, I always end up at bare metal again with no filler, and my repair started at one end of the door and now I've chased my tail to almost the other end of the door. I was thinking of hitting the panel with a hammer where it might be a high spot and making everything low then filling it, I did this on a small section on my other door by mistake and I think I fixed it lol. Is this a bad idea? The other thing is with guidecoat, whether it's the powder or spray, after I sand all the guide coat off, it doesn't reveal anything for me in terms of high spots and low spots and makes it especially hard when it's bare metal (at least in powdered form), am I doing something wrong here, or likely a high spot I keep going over and creating valleys? Lastly, stupid question but, is it possible that after sanding if I only sand over the filler area where I know to be a dent that it's impossible for me to dig into that dent? Unless there are other problems which I missed.
