I have machined the downpipe flange so that the pipe is an interference fit so welding the cast flange to the mild steel pipe should hold up OK hopefully.
It will likely be shorter than this but Ill leave enough pipe so that if it does crack I can weld a new flange on.
List of parts for the conversion now is
Megasquirt - Already in
LC-2 Wideband - Already in
Cleaned and flow matched 440cc injectors
2.25" intake pipework.
12" x 10" core intercooler.
Cast turbo manifold
Garrett TBO312 turbo
Turbo oil feed and drain pipes.
Should be pretty straight forward other than drilling the sump for the oil drain. Pipework is good for about 1.7 power ratio which should see me at 190ish with a nice quick spool so hopefully improve the low-mid range.
Cheers
