BAM S3 full rebuild for Hybrid or BT
Hello Guys n Gals
just thought id share that im doing a full re-build on my much loved S3.
Shes done over 115K and shes using a bit of oil, even on the 5W40 stuff so thought now is the time as i want more power and need to do the rods before i go any further so i may as well do the whole engine as she already has the Shark Stage 1.
Now this is where i need some advise as i don't have a ElsaWin yet and i`m stuck in Kuwait off-shore and cant down load one so i`m gonna need some technical service limits on various parts of the block especially clearances of cranks, rods, bore e.t.c
My head will be getting sent of to some one for remanufactured as i don't have the tools for re cutting, boring e.t.c
Any suggestions on this one? Port and Polished and heavy duty springs e.t.c
Currently i haven't started as the engines still in the car and need to get all my ducks in a row before i even pick up a tool.
First things first, the Block
I believe its sleeved but can i over bore this or does this need re sleeving? 81mm being the standard bore and 82.5mm is being the next size up? obviously i`ll need to take into account what other components like pistons and head gaskets are available to fit the new re-bore size.
Rods will be IE 20mm rifle drilled or equivalent with some after markey shells.
Pistons will be dependent on the condition of the bore, to match re-bore size.
Piston rings i would assume would come with the piston manufacture?
What is the stock gearbox good for power wise?
Clutch? anybody got good experiences with up rated ones?
Turbo, now this will depend upon what power i want, well right now any thing between 300-400BHP but if this kills the gearbox and Transfer box as i have a Haldex Blue controller on my S3 then i may have to remove and re fit the standard controller to make the torque split more front wheel drive than 4WD.
Ive mustered up 3K for this project so will probably be going down the Hybrid turbo root as i believe this is cheaper but with reduced power gains?
The machine is done my brother who full has access to CNC so thatll save me some pennies there.
As with the modding rule in Motorsport, you make some thing faster the every thing has to be accommodated for.
so with that being said i believe the Gearbox/Transfer box will be the limiting factor here.
As always comments and help is always appreciated.
