Fast and Luxurious: The engine
The old engine: B204FT, 2.0L 16v turbo (190 hp, 280 Nm)
The new engine:
- 1996 B230FK shortblock, Stock pistons with milled valve reliefs
- B234F head with ford 4.6 valve springs
- Yoshifab tensioner / volvo 850 timing belt
- B204FT, B234F or PZ-cams (not yet decided) with KL-racing adjustable cam gear.
- B204FT intake with 3" volvo 960 throttle body
- Bosch 440cc injectors (too small?)
- KL-racing header
- Holset HE351CW turbocharger, with ported wastegate
- AN4 oil intake hose, AN12 oil return line, oil return in block tapped for 3/4" fitting
- Walker V-band flange, 3.5" downpipe => 3" exhaust.
- 50 mm KL-racing BOV
Engine options:
- AQ171 crank and pistons for high compression 2.5L engine (E85 only!)
- UI/UA cams (B234F), PZI/PZA (AQ171), FI/FA cams (B204FT)
- KL-racing intake manifold or Cosworth YB intake manifold (modified with B234F flange)
- B204FT exhaust manifold
- 630cc siemens injectors
Gearbox/flywheel/clutch:
- M90L gearbox
- M46 dog dish flywheel
- 940 tdi clutch and pressureplate (763)
This combo should be good for around 440 Nm (will that be enough for a B230/16v turbo?)
Maybe i should install a sintered disc so it will hold approx 500 Nm.
Flywheel/Clutch options:
Flat lightweight JVAB or TTV flywheel/765 pressure plate/850R clutch disc?
Engine Management System:
Stock B204FT LH2.4.2 (950? ECU)
EZK (number?)
TCU (turbo control unit), EGT-sensor, Electronic Boost Control, spark retard (APC/turbo+)
012 AMM (3")
~330cc injectors
Planned ECU/EZK/TCU modifications:
- 630 cc injectors / modify injector scaling in ECU for larger injectors
- Modify ECU for datalogging / Ostrich tuning
- TCU/resistor mod to raise boost level to Holset efficiency range.
- Wasted spark / VAG coil-on-plug conversion (EZK-mod with attiny13 & Ipdowns VAG-cop code)
- Maybe disable the EGT-sensor if i can't find a new place for the EGT sensor.
- Innotive Wideband
Turbo/Exhaust system.
- Stock: T3 turbo with 2.75" downpipe going into 2.5" cat and exhaust system (same as 940 turbo).
- New: Holset HE351CW (internal wastegate), 3.5" downpipe, 3" cat convertor and exhaust system.
Pics of the new engine (mockup):
Welded a new downpipe today, not Nathan pretty, but it should hold.
