After a short hiatus in updating this blog, here comes an amalgam of few weekends.
Lets start by fitting the oil pan from the Volvo B6304F engine to the newly modified ZF GS6-37DZ transmission.
During this time, I took "accurate" measurements of the assembly, so I can see how much to cut of the firewall and also to share the information to someone who might need it and reads my ramblings.
The full length of the package is 1375mm from the front of the oil pan to the middle of the shifter.
Oil pan length is 615mm and the transmission is 760mm from the bell housing to the middle of the shifter.
Polyurethane Transmission Mount Set - Street or similar as there are quite a vast offering for these gearboxes.
I cut the cubby holder out (left most hole in the picture with the writing) and at the same time the front part of the transmission tunnel.
The writing and the line marks where the middle of the shifter assembly will go.
That is 150mm further back than the original shifter and the firewall will receive the 200mm (IF I would like to enter this car to the Finnish Time Attack series some
time in the future, the maximum I can move the firewall is 200mm) deep pocket for the engine... Hello front middle engine Z!
It's quite a package, but should be doable (I really really hope so) as long as I get all the measurements right and think this through...
Measure once and cut two times, or how that saying goes...
Also there could be a nice room for the turbo in the old battery location... we shall see, if that's feasible!
Bottom of the oil pan sits at the same level than the frame rails and a bit (15mm?) lower than the front subframe.
I'm not planning to stance the car or make it obnoxiously low, so this should be quite good.
Although, if I could shorten the sump, then the package could sink a bit lower still. Another route is a dry sump system for maximum lowness of the driveline package.
It's a bottomless pit... a real life Pandora's Box!
Fortunately it was quite chilly in the garage at around 10 Centigrade so no larger warpage to be seen as the metal did not heat too much.
Final results will be seen after grinding the welds, but might be quite nice with minimum body lead needs.
Here a sheet metal brake would be really nice, but I'm quite happy about the outcome! Nice straight bends and accurate measurements.
I'm using the center of the carosserie beam as reference and as it now stands with the floor and edge of the kicker panel, they are as center as I can get them.
Those Clecos truly are nice tools to hold multiple sheets together!
I decided to make the floor from few pieces as I would in any case need to tie the coming transmission tunnel to the flooring so few more seams are not going to brake the bank in this project.
I will be making these kind of dimples to the floor and weld the majority of the 22mm holes shut with planking plates, but plug few with rubber plugs and use them as water holes if need be.
Should stiffen the floor quite nicely!
That's all again folks!
