Default EFR6758 Dump pipe

Hey All.. Im coming to the closing stages of a TD42 ti conversion into my ZD30 03 ST wagon.. The research done on this site has helped a lot.. Ive fitted A Npc Billet flywheel and Viper clutch..(some wouldnt do it) The motor was a low k ti from a n 06 trayback.. To this ive fitted a DC6 Pump (mechanical).. A Cross Country modified inlet plennum and a CC ultimate top mount I/C.. Ive extensively ported the log style exhaust manifold(low Mount).. To this i followed a wise mans research(OLD MAV)and fitted a Borg Warner EFR6758 turbo..Now the issue i have is this turbo dimensionally is much longer than others.. This means i have very limited space (80-90mm) to fit a 3" 90degree dump pipe... Has anyone got any photos they could pass on..( i know this is not a common mod)of their efforts? Thanks in advance..

I am not good at remembering to take photo's. You need to source from an exhaust shop or internet a 1D 3 inch radius bend Caboolture exhaust and mechanical usually have them in stock.

You simply cut down into the first part of the radius with the V band flange tilted at a angle to fit STD exhaust position for clutch slave cylinder clearance. You need to do a bit of metal massage to get the pipe into the flange recess. I removed most of the Vband recess around the bottom or the inner radius bit. This allowed a 80mm bend so about 10mm clearance to the firewall insulation on a GU for the curve.

I simply brought a STD 3 inch exhaust for a GU ute and cut the STD flange off and welded the dump pipe to it, hence why the slightly forward angle was needed to fit up with the STD 3 inch exhaust system.

Do you think it's worth having 3.5" after the dump assembly for the rest of the exhaust pete?

I don't see any value for a 4.2 litre Simcoe except pain to fit. I have checked back pressures @ 200ish rwkw's many time with and without a straight through muffler.

The maths doesn't equate to any significant gains or losses here and I have done many calc to prove it on many different turbines. Once you get to 1psi back pressure you do see a push back on the comp chart PR point slightly moving back a tiny bit towards the surge side at peak torque and beyond.

I would suggest once you have the exhaust gas produced from a 220+ diesel engine 3.5 inch would be a must probably 4 inch to equal our about .2 to .5 psi (with muffler) on our TD42 @ 200rwkw. It really depends on torque value not KW's but its does effect both more so peak torque and its slope after. 900Nm's would be my suggested limit for 3 inch exhaust straight through system mandrel bent.

Oh just to note there is a crock of sh#t on the net about back pulsing and so forth on turbine wheels. probably petrol and would have to be in the 10K plus engine rpm for this to happen. But there is a few very old in German white papers explaining what you need to do if you are seeing radical turbine shaft stall issues with turbine wheels. You clip the outer wheel trim to remove the stall, you don't do fancy, silly and strange exhaust systems to fix shaft stall..
