The 2nd Gen Sprintex Owners Thread
Due to the original thread being 99% about the old unit and it's issues, I think it's time for a separate thread for the newer 2nd Gen units.
How to to determine if you have a second generation Sprintex?
The fill plug located closest to the belt will actually be a dipstick instead of just a plug.
Known issues carried over from the 1st generation kits: (Send PM if you have others)
Issue:
1. Faulty Tensioner / Fix = Bytetronik / GPR Tensioner
2. Light oil consumption / Fix = Bytetronik Vented plug
Known Belt Combinations: (Send PM if you have others)
ATI 2% / Stock Pulley (15-16psi) / GPR Tensioner = Continental 6PK1388
ATI 2% / 64mm Pulley (17-18psi) / GPR Tensioner = Gates K060539
ATI 2% / 60mm Pulley (19-20psi) / GPR Tensioner = Unknown
Pulley Options:
64mm and 60mm Pulleys available from KAVS Motorsports Here
Oil Change Capacity: 111mL of 75w90 Gear Oil

The tensioner still uses your existing OEM damper/shock, and is not included, the choice of upgrading the bushings is no different than with the stock mini setup, it's not a "must do" item unless you think it should be done.

Installation
If you have an R53 that has never had its harmonic balancer changed you will not be able to install the GPR tensioner, its too tight, lifted lowered the engine, impossible especially with the damper installed on the GPR, I've installed countless of oem belt tensioners on the R53s without removing the engine mount but the damper wasnt on untill tensioners were in place, GPR is a touch bigger and its bearing part that connects to the supercharger is a one piece, getting it past the sprintex pulley impossible, instructions are for earlier version. I will be taking the never changed harmonic balancer off and it will be ok, just a pain in the butt for us with the never changed harmonic balancers...good luck, unit looks amazing cant wait to have it all done in a couple of days...2002 R53 version 2 Sprintex...

Installation completed
GPR tensioner successfully installed by removing oem still from factory harmonic balancer, the thick one, then replaced...i did have a rattle i thought from the oem tensioner that came with the Sprintex, but its another issue...did have oil light on so could be my oil pump...but anyways tensioner looks amazing car at idle sounds great, just while I push on the gas it starts rattling..,may even have loose chain...thanks bytetronik recommend the GPR performance tensioner

Timing chain tensioner has been removed by taking the valve cover off and with a long screwdriver with care was pried out...ordered new one be here on Tuesday 7th Jan...then we really get to test out the GPR performance tensioner.....have the vented plug in place instead of the dipstick, gear oil 111mm is replaced and a new belt....GTi I'm looking for you hahaha

Hehehe I've just started with maintanance on this R53 i picked up for $800 hahaha engine in the car overheated guy sells it being told by a mechanic it needs a new engine...all it needed was an electric water pump as its a Sprintex Supercharger...saw on YouTube a guy with the cheapest r53 $1450 in USA...think I did better than him hahaha thanks Bytetronik for my GPR performance tensioner and vented plug
