Heya guys, here's a few pics of a current project. It's a total sacrilege build, It won't be clean enough to be a hot rod yet not traditional rat as it'll have a german drivetrain, fiberglass body and EFI. For lack of a better description it's a T-bucket I want to build with the means I have available and in my budget
Let's start with the engine, it's what I started building long before I had the idea for a T.
Late 90's BMW 4.4L (M62B44) short block:
Also picked up an early 90's 4.0L (M60B40) to donate it's heads, cams, timing covers (for obd1 sensors) and misc hardware:
Measuring piston height of the 4.4L M62, the pistons sit +.025: above deck and have a slight dish to them. I've measured roughly 4cc of dish.
4.0L heads back from the machine shop for mill & rebuild:
Measured 52cc of chamber volume. Using a 1.74mm MLS head gasket I've calculated roughly 9.6:1 static compression
Setting up cam timings:
Measured a 211° Int & 206° Exh durations @ .1mm, using the cam timing blocks pictured above ICL was 108° and LSA also 108°. I've set the cams up for a 110 ICL° and 112° LSA to help take advantage of the belt driven intake manifold:
The supercharger is an Eaton M112 from a late 90's Jaguar. Using the jaguar water-air intercoolers and injection sitting on adapters to bolt down to the BMW heads.
The supercharger needed minor modification to fit the BMW:
Of course what supercharger wouldn't be complete without nitrous:
