The first installation job with Jyri (my machine shop and welding
specialist) is the exhaust manifold. It's of the 4-2-1 type with constant
tube size to keep up high flow. The tube size is 42.4 mm x 2.6 mm. The
manifold is very short with good flowing joints.The tight curves are from
the local hardware shop and the longer ones from the firm
Last weekend Jyri made the pressure box (from sheet metal) and today he
continued with the turbo flanges. The design criterias were functionality
and rigidity without any bling. next weekend we're trying to instsll the
turbo. The downpipe and exhaust pipe will be custom made. The internal
wastegate will have a separate exhaust pipe which blends in the main
downpipe as far away from the turbo as possible.

Here are some of the turbo "kit" prior to the ibstallation. The turbo has a
2.5" downpipe and the pipe size continues in the exhaust until it joins
the original exhaust pipe.

The first driving experience are very
positive. There is alot more torque in the low rpm's and the start off is
good. The Bosch EZL ignition is in its original S position and the next
thing is to start tuning the fuel mixtures and boost pressure. I guess
i'll have to think about an intercooler, too. The more efficient radiator
with electric fan awaits its installation.
