Jonas Wikströms Volvo 142
The engine in this car is a stock Volvo B20 with a need of retirement. A refurbished B20 is taking it's place only with a very much upgraded head and longer stroke. Basically this engine is an inline 4 cylinder, with no electronic control over anything.
- 2.0 litre inline 4 cylinder Volvo B20A, completly stock
- Custom crank trigger with Honeywell GT1 Hall sensor
- Single coil and distributor ignition
- Sequential fuel injection with no cam sensor and high-Z 192 cc/min injectors
- Custom intake manifold adapted from Volvo B20E/F engine
- Custom engine harness
The future upgrade is a stroked and bored B20 block with a heavily ported head and aggressive cam (300 degrees duration). The fuel injectors will be 300 cc/min with the possibility to run alcohol fuels. Approximate crank power is 170-180 hp, compared to the stock 85 hp.
The intake manifold has been ported out and the throttle replaced by a flange for a removeable 65 mm BMW throttlebody. Fittings for a fuel rail and regular Bosch injectors has been welded to the runners. The runners have been ported out and smoothed. Here are some pictures of the manifold as it is mounted.
Not that there is no throttle linkage, it will be fixed later this week. Also, the engine bay is not that pretty but that will all be sorted out after the engine has been replaced.
The intake was gutted to get it ported out and then welded shut again.

Update 2005-10-07
This car has been started up with VEMS as of today, ignition only. Trigger is through a Honeywell GT1 at the crank with a custom trigger disc. Spark is through the stock distributor, the car is already running much better due to not having to rely on worn points in the distributor.
Fuel is for next weekend, everything but the fuel plumbing is done. Stay tuned.
Update 2005-10-15
Today the carburator was removed and the fuel injection manifold was mounted to the head. Started right up after increasing cranking pulsewidth and thereafter req_fuel to get it idleing.
You can download a short movie from the moment we got it to idle well, right [here] (15.4 MB).
