Sorry my bad. I assumed that going a 3L you would upgrade the supporting mods, water and oil pump, timing belt, clutch and at least a dyno tune. Obviously not the case, I apologise.

You can't do it without a timing belt. Water pumps are cheap as. The rb30 oil pump is fine. Shim the relief valve for free.

And I tuned it on the dyno.

Cmon Ron. Hurry up and get your timing right so you can go back to not fixing the bov return.

I bought one and it bolted up to my stock airbox going to a 4" snout of a Hypergear SS2. However, I liked pigeons and tuuurrkeeys more so I installed a pod filter to attract slarts & cops.

Micko Atleast knows where his timing is sitting... Just saying.

Widebands are the best.

I also thought my car was running rich.

Bought wideband.

Doing a RB25/30 conversion for less then $3k can be done IF you can do all of the work yourself and all good and well these guys say you can cause i did it is not a fair statement, you couldn't take you car to someone ( and not a mate ) and get it done for that, no way in hell

It also come to what supporting mods you do and to what level and how properly you do the conversion as we all know there are cheap way to do some stuff which isn't exactly the best way of doing it

So the real question would be can Ron do it for less then $3k done and dusted ?

Again with the wide band, if tuned properly you shouldn't need one, nice to have but not needed cause really you can only do so much on the street before it should be put on a dyno and tuned properly

^^ This really clever fellow here knows me more than I know myself !!

Yes.

It's based on many things you have posted.

For example.

You specified how exactly you were going to block up your bov return. And did it weirdly anyway.

Someone who knows what they are doing just does stuff.

I do really hope you can get the car sorted out.

22 pages on AFM vs. BOV lol

I reckon, sell Power FC, BOV, AFM - buy Adaptronics, block up BOV port/return dose & bake tyres all day

True enough for anything over 100kmh with a power run. The 97% of the driving you use a street car for however can be done with a wideband and some tinkering. The power runs is what the dyno is for but that is really only a small fraction of the time (money!) it takes for a tuner to tune the car, but I agree - it's no dyno replacement.

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      (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.
