...Not again :|

Reason? I managed to change the engine position after modifying steering rack mounts, so when I renewed engine mounts I positioned it as low as possible and even further back. Besides the welds looked terrible now that I've learned to TIG somehow :roll: Upcoming version will be looking quite different.

Now that I got the taste of cutting I cut the comp housing outlet too:

To change it to this:

Few Finnish fellows were inquiring M20/M30 cam sensor covers from us as we had made some 3D printed prototypes earlier (in co-operation with Juuso's Garage), these anodized aluminum versions are about to arrive soon:

One more aluminum tank.. Fuel surge tank that has been in progress for a loong time. It needed a baffle inside, end cap and AN fittings for fuel in and out, unfortunately AN6 fittings were out of stock at the local store so I wasn't able to completely finish it :x Underneath my FPR with AN10 in/outlets:
Image

Finally got this part I've been waiting for, shiny aluminum bit from Italy:

Okay where were we..

Oil pan bolted to the engine and it still fits, couple of small additions need to be done before I can say it's complete. Oil stick will be attached with AN fitting, as easy as it gets:
Image

I ordered a batch of AN12 fittings and hose for IC water lines and oil breather lines (yeah I already welded stupid hose fittings in the breather can so I need to change them):
Image

Had to push the car out while cleaning the garage, notice my nice new wheels:

Thanks! I'll continue with the bodywork now that the weather gets warmer, two corners have a good progress, but still lot to do :)

AN12 hose is 17,5mm ID, but fittings are 15mm. The Bosch water circulation pump for the intercooler has 15mm ID connections, so that hose size should be ok for the application.

Some pictures before I cleaned the garage, the reason why I have now worked with the car outdoors:
Image

Image

Today the driver side rear quarter looked like this, soon getting ready for molding. Front fenders are almost done too, some minor spots that I'm not happy with, but after all it's going to be a race car, so... :roll:
Image

Image

Batch of these were sold out quite quickly, so if any of you M20/M30 builders are interested send me a PM or contact via facebook, new batch is coming.

Bodywork fabrication continues, driver's side is already quite good. I remade the side skirt model which is much simpler, lighter and should work better. I'll take a picture for the next post.

Before I cut the hood I made a tunnel for the radiator, all the air goes in front bumper and then exits the hood vent, should be effective enough.

I tried to remain some orginal body shapes yet not forgetting functionality.

I spent few days with the hood before our holidays, to be continued next week. To perceive the next part of the puzzle I already cut the front bumper in pieces :)

Me neither, but I think that's a lot of work :lol:

Soon it's time for updates.. Tomorrow I should be able to lay some fiberglass to front bumper, currently it's riveted together with sheet metal pieces. Spending my holidays from work so I've got time to make some progress hopefully :)

I got some interesting parts in my hands lately, makes me rethink my front setup:

So... the front bumper. This is how it looked with sheet metal "mold", quickly threw together for next step:
Image

Some fiberglass laid behind, total 4-5 layer was used to get enough stiffness:
Image

Took off the sheet metal parts and this is the result, next some filler..
