One more picture of the finished prototype with trigger wheel added:
I was thinking to spend this weekend strictly at the garage, today I continued some aluminum welding and I'll probably post more updates in the end of week..
Clutch setup arrived, probably not going to use twin mass flywheel Now that I also got silicone hoses I continued welding, first mounted a throttle body: Then the other side, that's the only place where I was able to mount blow off valve: Some coolant pipes and new mounts for the power steering pump:
I had some struggle machining the oil pump back plate manually, I did two versions which didn't turn out too good. I also tried a shortcut welding a sleeve into the orginal cast cover.. Because of the high Mg content welds won't hold even if they would look good, here's the result of light hammering, crispy:
It was time to start over, I did some changes to model and discarded the idea of a water jet cut blank because of it's ridiculous price. I happened to find a company which would machine the part for me very cheap with their 5-axis machine. I just confirmed it fits by 3D printing a mockup: The final part (made of AW-7075) should arrive in three weeks
...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 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:
Oil pan project: Front sump is only to clear oil pump: Long welds: Oil pan baffle with trapdoors, screws are only temporary, those will be replaced with rivets: Assembly taking shape:
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 Underneath my FPR with AN10 in/outlets: Finally got this part I've been waiting for, shiny aluminum bit from Italy:
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: 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): Had to push the car out while cleaning the garage, notice my nice new wheels:
Some pictures before I cleaned the garage, the reason why I have now worked with the car outdoors: 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... 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
That's going to look awesome! Are you planning on keeping the vents as they are now or will you be putting some sort of grid over? Not sure which will look better or if there is a gain with either.
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: Some fiberglass laid behind, total 4-5 layer was used to get enough stiffness: Took off the sheet metal parts and this is the result, next some filler..
