Hi, not new on here but havent been on for a very long time!
Im 20 and currently work as a fabricator mainly doing mig work (1mm up to 15mm mostly)
I attended fabrication college doing MIG & MMA in mild and TIG in stainless but unfortunately i havent really touched TIG since i finished a year ago.
Im building a Mk1 nova track car using a turbo'd E16SE engine, unfortunately you cant buy an off the shelf manifold for these. Im using a T25 turbo and aiming for 200hp, with the view for more in the future depending on how well the setup works.
I have a few questions id like to ask as to actually fabricating the thing;
I plan to use 304L sch10 butt weld fittings for the manifold with 10mm thick mild steel flanges, I plan on using 309L for the stainless to mild joints and 316L for the stainless to stainless joints, Does that sound sensible?
The exhaust ports on my cylinder head measure at 28/29mm (theyre not fully round) I have a 304L sch10 90 degree butt weld joint that measures 27mm internal even though its sold as 1"nb, would it be good to for this for the runners on the manifold or would it restrict and be better to get a 1 1/4" nb joint and see what that measures up like? from my understanding a slightly smaller runner wouldnt hurt as it would increase pressure in the manifold = quicker turbo spool?
any advice appreciated, im open to any abuse/tips/advice etc!
