Boost Junky

OMG I want it jealous...

Good choice man. Im running a Link 3 should be mint, pricey but well worth it. With projects like these you kinda gotta be serious and serious with how much you spend also lol. How much power are you aiming for? If your motor is still in descent shape I wouldnt bother with forged internals.. Your motor is the M50 right? The bottom ends in those are good for 450 - 550 hp providing you have a really well tuned ECU, decompress it with a thicker MLS head gasket and bigger injectors and sufficient fueling etc... My manifolds not tuned length and it will be fine, tuned length is a very expensive way to go. So your manifold should be fine. Mines top mounted haha my bonnet wouldnt shut at one stage had to drop the turbo and wastegate a little bit to get it to fit. Keep us updated on your progress man and some pics would be nice Luke

Yea Riley be good to get some more. I just gotta get the manifold sand blasted and heat coated then im gonna take a pic of it and all the intercooler piping on the car etc not far to go now

That touch of glitter is just perfect Matt! Looks awesome dude.. i rekon that colour would be a mean colour on the car too

OMG haha I saw that in ur pic Mattzy and thought you had done it for a certain reason lol! I wondered why you had three holes spare, Good spotting bravo. D idnt know about the pre loading of the hanger bearing so we all have learnt something from this cheers

Your running spacers aye? Could it be something related to the wheels or spacers? Alignment etc.....

Ok a slight update everybody. Manifold is 99.9% done everything is fabricated up and I leak tested it tonight by filling it with petrol. Found about 4 leaks which need addressing so my mate is going to fix them up tommorow. Dad is going to sandblast the manifold out at his work then I will paint it with some 1600deg paint prob just black. Finished off all my intercoooler piping last night and my mate welded it all up today so thats all done. Hopefully purchase my oil/water lines in the next two weeks. I will place some more pics up when I get all the bits and pieces back. Luke

Hey man, could be your driveshaft hanger bearing? Also had you ever driven the car before you started the project? Could be a simple fact that the driveshaft is out of balance.... Its normal to be able to see the part of splines where the two shafts connect as the shaft will slip in and out slightly as the motor shifts forwards and backwards slightly under acceleration and deceleration.

Yea fair enough man. Less temptation to do certain things with a clutch also right?

Oh so they use wastespark due to the fact they get a stronger spark? I always thought it was because of reliability. Well that sways me back towards keeping the individual coils, Cheers Glenn. Luke

Oh yes. If there was any other motor I would run in my car it would be a JZ I agree, awesome how your doing video logs wish I had done so now, slack with even keeping up with pics. Do you think you would eventually goto manual? Cant wait to see it running

Did you sort this out bro? Pretty sure the end tank can be chopped off and welded. Do you know anyone that can weld alloy? I have plenty of sources up here but im 3.5 hours away haha

Awesome. Haha that wastegate pipe is long! Is there no other way you could fit it? What size/brand of turbo and wastegate are you running? ECU? Be interesting to watch this develop, looking good so far.

All I can say is lol aye Cam You newer folks will soon learn that you will get by much easier by searching first May as well add in also, Im sure I read somewhere on one of the UK or US forums that a fair few people have had vacuum leak issues with the whole M50 inlet manifold on the M52 head... More hassle than its worth by the sounds. Luke

Hey man. That would be cool too see a supercharged M50 on here, im doing the turbo conversion myself be interesting to compare haha. There should be a few posts in the projects and forced induction sections which should give you an idea of what other people have done and costs as far as turbo goes etc... Mines in there if you want to have a look and..... google is your friend

Oh yes i get ya now. Because of the extra holes/bigger holes, more fuel is going to come out in the same ammount of time that fuel would come out if there were less holes/smaller holes. Im sure the SARD RRFPR's are rising rate, problem is the manual that came with it is all in Japanese and so is the box. Only thing I can see on the regulator itself is "SARD FUEL REGULATOR" and under that "200-800kpa.... Ohh of course Mike. Because there is a certain amount of pressure in our atmosphere already which is 1bar as you said got it now. I would have thought that also because you are starting to get possitive pressure in the manifold...

Get a link dude and be done with it. Do away with your air flow meter and also who ever tunes it will be able to setup your vehicle in the correct way i.e where everything hooks up and the correct parts to use like your Fuel Pressure Regulator etc..

I was leaning more towards the reliability of individual coil packs, but i supose my coil packs havnt packed out YET. I just want to make sure i can cover as much things as possible before I take her to get the link installed and tuned, narrow down as many possibilities as possible that could causeme to have to take the car away again and come pack to pay for more dyno time. I've seen a few, more descent turbo setups on M50's on BimmerForums with waste spark setups. They must have a reason for doing it. Wether its the fact that the M50 is not already wasted spark firing or due to the reliability of the coil packs? Luke

Hey people, Does anyone know what parts I would need to setup a waste spark system on my M50B25 motor. Want to do away with the individual coil packs. I know I need individual leads but am insure if I can use the same coil drivers as what the RB's use to covert to waste spark. Maybe the commodore coil packs? Have googled and looked on bimmerforum and e30tech and various others but cannot find alot Cheers, Luke

No problem, I think I have a windscreen washer motor is that what your after?

Bumpty bump

And locals always ask me why I didnt just RB mine haha You will find an RB in just about any kinda Japa vehicle round here Danny. Even a 1JZ has to be better and they are pretty cheap now.. sound cooler too haha

Whoa, well that clears alot of things up Mike. I now understand that the vacuum or boost in the manifold adds to the amount of pressure in the rail via the vacuum/boost line that runs to the FPR. So this keeps the correct amount of static fuel pressure coming out of the injector. Obviously this static fuel pressure rises with the extra air flow coming into your manifold as you give the motor more revs, but that amount of extra fuel is controled by the ECU correct? I always thought the FPR controled how much fuel is injected where as now I understand it controls the pressure at which it is released? Were all your figures correct Mike as I got a little lost where you were explaining how if the manifold pressure rises to 1.1bar (0.1 bar of boost) then a 10:1 RRFPR would raise the pressure to 5 bar at the fuel rail. How is 1.1 bar, 0.1 bar of boost? 1.1 bar is 1.1 bar i would have thought... still not a 100% clear on how the RRFPR works especially when ratios are involved lol im not too good with them.. Thanks cam, so obviously bigger injectors have a longer opening period which is good for high power setups where they need alot more fuel to compensate for the extra air being forced into the manifold. But they are a bit much for idle where you have vacuum and dont need much fuel at all? This is because they have a longer minimum opening period correct? Haha what a science lecture we got going here... im not sure if any of that made sense but it sure is interesting Luke

I support your decision with the Link. Im running the Link G3 but not the plus or anything fancy. Good thing about them is the fact that they are NZ made which is great for support and they have come along way now and produce a reliable control system for just about any vehicle now. How great is your understanding off fuel maps and ignition maps etc? Have you tuned before? Tuning is not just a simple task that even some tuners can carry out perform adequatly haha.. Its the most vital part of having a realiable setup especially when boost is involved. I dont know where your at with your abilities regarding automotive tuning or mechanical skills so you may be more than capable If not i would pay the money and pay a profesional to do the job, as like I am. Im fine with mechanical stuff and computers but automotive control systems and tuning... well thats a whole new world to me lol. Just my 2c Luke

Haha oh man way to loose me.... my cars diamond shwartz. So yea anyone got one lol?
