Yes, And I encourage it actually! You can Source them from Ebay, Trademe or Your Local Salvage Yards or Parts Suppliers usually.

Please note below is a list of all the compatible superchargers our setups use.

• SC14 from Toyota Previa/Estima Vans, (Yellow Dipstick and Cross Face Pulley)
• M90 Eaton Short Snout from Jaguars.
• M62 Eaton Short Snout From the Mercedes Kompressor,
• M45 Eaton Short Snout from BMW Mini etc.
• M122H Eaton (not the old M112) from The Ford Mustang Shelby GT500 (2007 – 2012)

Yes, I ship world wide, no problem. Prices typically Include International Shipping & Customs.
But feel free to email me to check if extra fees may occur to ship to your location.

I strictly prefer to use Paypal for international clients, if you are in NZ, I can take Bank Deposit.

Should Paypal be unavailable to you, I can also accept Bank to Bank Transfers or Western Union and such for international clients.

Depends on the Supercharger Setup used, Power is relevant to Amount of Air Flow CFM, Not Boost(PSI). Hence on a smaller older blower you must overdrive the blower to get more CFM, while a larger or more efficient blower can push more air at the same boost levels.

That Said. Dyno Records Suggest 3PSI or from the SC14 you can see around 25-30WHP (Around 35HP at the Motor/Crank). 8 PSI Should give you around a 50% Increase on most of sitaight six engines.

For More Power You Must Look into the M90 and M122H Setups. The M122H is 650HP Capable, In Particular would be around three or four times that of an M62 or SC14. And 2.5x the CFM of a M90.

Depends on the Supercharger, Engine & Pulley Used.

With the SC14’s Stock Pulley You are looking to make around 3 – 4 PSI on a 2500cc – 3200cc BMW Motor, Smaller Pulleys are available to take you to upto ~12PSI. For a Street Car with Stock Engine, Its Advised to have a Intercooled 8PSI Setup for Reliability,

NOTE: Boost itself varies and is much dependent on your motor, and any modifications done to it, as cams, intake, exhaust; then a good quality blow off valve setup right, use gfb/turbosmart/tial and well lube them, you dont want a stuck open valve bypassing all your boost and a good boost gauge itself, and finally its dependent on the supercharger drive pulley size used as well as the right belt. Another example the Stock 113mm Pulley produces around 12PSI on our tests in a M40 motor, while the same blower will produce average around 3-4 PSI on a M52B28. As Motor size goes up, boost goes down.
Easiest pulley is the 93mm one from the Toyota Corolla 2002 SRC Aircon, Some people even go as far as using custom made pulleys.

I can only give an Rough Estimation but a budget of $2000 if you do most of the stuff yourself should be enough. Even cheaper if you or a friend can do all the pipe work yourself and just buy the brackets or designs off me!

I would recommend that you do.

It will run a bit rich but quite well on the highway, so leaves you with plenty of room to tune it when you like or can afford to, To use its full potential get some larger injectors for around $100, On the prototype I am running more power then the stock kit and currently using larger 36lb injectors and a Custom Tune. If you are on a strict budget or looking for Remote Tuning, Then there are many around the US, UK, Europe & Russian BMW Communities that can point you to the right direction. I myself know a few Tuners who may be of assistance.

Most Stock DME’s Are Typically Okay for upto 5PSI. Some Pre 1995 (OBD I) such as M50 and M50TU Motors have DME’s that cant just be flashed as OBD II (1995 and After), Such as M52 etc.
I have run the stock DME MS41, Stock Pink Top 21.5lb Injectors, Stock Fuel Pump, Stock FPR and everything just reworked all around to ensure its all 100% working or new. Theoretically your Engine knock sensors generally kill most predetonation caused by running lean and if you do run lean, your oxygen sensors will tell the DME to send more fuel through. So the car will in time adapt a bit however word of caution it will likely run rich and the MAF & DME will need a proper tune to utilize true potential and to iron out the minor issues you encounter.

I have personally worked with quite a few National & International Tuners in Europe & America. Among few that offer their humble services to public

David Markert @ Markert Motor Works – Based around Lawrenceville Georgia, USA, Dave & mutual friend of ours have been a tremendous help in 2016 in resolving some fine tuning issues and developing a custom tune. Hes got a great deal expertise working with these cars on a daily basis.

Andreas Fekzen in Sweden @ Fekzen.se – who has helped with constant refinement in tuning it last year in 2015. Hes got some Chip Tunes, specially if you got older Pre OBD II cars produced before 1995.
Enda Wards from UK @ EndTuning – If you are in the UK, Enda may be your go to, the prices are just right and we have discussed a few things initially every now and then and found Enda to be quite helpful with some information I was after.

Gavin Ballers @ Hi Velocity – If you are in New Zealand and looking to pay for a comprehensive Dyno Tuning, then go to Gavin, His time maybe a bit expensive but he is the best BMW Tuner you will find in NZ.

This is only do able on certain ECU’s, Like the MS41.0/.1.2 and MS43 to a degree (even though that may need to be sent in to somebody). I suggest you go have a stroll at RomRaider Project & RomRaider Forums,

Alternatively if you are on a budget, even look at Piggyback ECU Options we have used include such as Ostrich 2.0 with Tuner Pro, Works Great on OBD I Cars, Also there is AEM FI/C 6. I recommend going this way if you are using the M122H type of setup and you don’t want to hire a Tuner, that is if you are looking to make more power. There are people who just get away with using an raising rate fuel pressure regulator & AFR gauge, the old fashioned way with low boost!

No, That is already taken care of in the bracket designs utilization of using the OEM BMW Belt Tensioner and the Right Sized Belt, Just use a new mechanical / spring type belt tensioner since the old one is due anyway.

Now If you put a smaller pulley, you get more power by over driving the blower to its max potential and higher intake temps. You can always add water injection and or a intercooler, But with smaller pulleys you’ll also come across gradual slow belt slip sepcially if you are using the original belt tensioner that came with the car decades ago, slippage will cause boost drops at high rpm, hence you will require more belt wrap around the pulley, For older M5XSC14 Setups we always have a simple secondary tensioner system which will be free (templates) addon for existing M5XSC14 setups to allow the use of very small pulleys with belt wrap.

Yes, I proved that in the calculations here, People are using more efficient however smaller Eatons on these cars, SC14 would be fine just as long as you keep it under 14,000 RPM, Meaning you are likely limited to 8 PSI at best with this setup if you want the supercharger not to wear out too fast. Then again, remember most motors stock are only good for up to 10-12 PSI without being rebuild.

I have a full DIY basic services guide for the SC14 blowers written on my blog here.

It may not be very flashy, it may be a small hobbyist monkey business, Often do good things come in small packages. If used right in conjunction with other modifications, this kit has potential to not only be versatile, reliable and an economically worthy learning experience, but ultimately rewards you, the Average BMW Enthusiast, Forced Induction Newbie, Students, Young and Old with your same humble car now far more capable then most of BMW’s top of the line offering, you wield a wolf in sheep’s clothing, all at your disposal at a fraction of the cost.

Potential at the reach of your hands is what this project offers and its evolving with every new build!
