Just thort id start a thread for my project! Ive not done much so far but ive already done the m50 conversion and its runing sweet. Ive bough a gen1 Eaton m90 twinscrew charger from a jaguar xkr and ive just rebuilt it.


Plans are bigger injectors
Relocate the tb
Standalone managent or a chip? Dependant on boost levels etc
Custom bracket
Run it from th a/c puley
Intercooler etc

So watch this space! Eny advice is highly appreciated also..not many people blower them so i thort bugger it..everyone loves a whine, apart from when its from a complaining woman!

Do you have a compressor map for that supercharger so you can succesfully run the charger at the right speeds and choose how much power you are after?

From there injectors sizes and possibly tuning choices can be suggested.

How do you mean mate? Im going to run it off the ac belt pulley and use the stock pulley for the time been and plumb a boost guage in to see what its doing. All help/advice is appreciated

To properly run a supercharger you need to know at what charger speed you need to run it for the engine. I.e the pulley ratio between the charger and the engine. To do this properly it´s best to know the airflow/pressure character of the supercharger and then math out the ideal speed so you can then figure out what pulley size you need on the engine or charger to get that speed.

would love to see this makman,i need to come over in my e30 its on the road now and i only live at sharlston .are you going to the nostel fueled society show?

Sweet moogie..to all things above aha

Eaton m90..custom brackets..custom belt & tensioner..custom intake & re routed afm and icv. Needs some 440cc injectors and a miller war chip. Adjustable fuel reg. Yeah..she runs now aha need a custom boost pipe making and a fitting for the forge 007p valve. Running no cooler as of yet due to around 9psi. Im also aware my boost guage says turbo....

Looks good mate.try aus or usa ebay for the injectors.just got my 42lb injectors delivered today

How much for matey? Does eny
one know what m50 injectors max out too?

Little cheeky un lol

I won them on an auction for $26aus which is about £15 and postage was another $25aus
all in all about 30quid to my door
genuine Bosch ones too
they are used but will be sent off for a clean and need o rings etc.

looking good mate

hi mate looking good i am in the process of twincharging my 325 turbo using a eaton m62 'charger..got it initially mounted up, and am using a m50 serpentine crank pulley instead of m20 a/c pulley to get everything running before getting custom pulleys made for more boost-how did you line up the s/c with the crank pulley? is a straight edge across both enough to get the belt running true? cheers, cant wait to see yours when it is done ash

Yeah ashton a straight edge is what i used..got it sat against the waterpump pulley and pas pulley then when by eye..made my brackets adjustable too so i fine tuned it from there. Also made a custom alternator bracket and tensioner system for the alternator to run from as thats where the AC pump used to be. The alternators gona be running from the Ac pulley from the crank too. Nearly done now tbh..just need to weld a fitting for a recirc valve onto my charge pipe then fit an adjustable regulator for the time been. Can you post vids on here from mobile? If youve got fb pm me your name and il tag you in the vid if not. Sounds iimmense haha

Need some 440 bosch green top injectors if enyone has a set of 6 for grabs?

Speak to James at injector tune he will be able to supply you with what you need.

nearly done!



trying to retrofit an s50 m3 coil pack cover on lol

got my new radiator for it, need to make some new brake pipes up and plumb in the hydraulic handbrake and some other little bits then shes good to go!

running bosch 440cc green giant injectors and a miller war/402 ecu with a base charger map/330cc injectors, so il fine tune it with my wideband and hopefuly make some good power!

tune is for 330cc injectors sorry.

looking very nice that mate,you taking it to fuelled society again

Sweet ride man! Turbo Tim bought back some memories too. Let's see that vid

Any updates on this? My twincharge project is crawling forward and i need some inspiration!

dont think Mackie is updating this much but there has been issues with the ecu and map i think
