Ive got a hks manifold with wastegate (not installed yet) but my 2535 uses an internal wategate. Is it possible to weld the internal wastegate and simply use the 40mm exernal wastegate?

I guess the benefits i would like to see is that the airflow from the wategate and turbo are separated although this can also be achieved by a a split dump pipe...

can anyone shed some light

Im thinking of doing the same wit hthe same turbo :(

I was going to get another dump pipe flage and weld flat flat on it. Then cut out a hole for the turbine exit (i think it's roughly 2inch) then step it out to 3inch.

you have to weld the hole where the wastegate flapper is

then make sure its smooth on the inside so it doesnt hinder flow

no you dont, just make sure it cant open, welding up the wastegate hole in the housing will just cause you dramas such as cracks, and it will take 100 hours to diegrind the weld down so it is smooth

of course you dont have to

but if you dont do it properly its just hindering flow :rolleyes:

I dont want to tack the flapper so if i sell the turbo. Instead i will make a solid rod(take off the actuator) so it is locked and wont open and if it do'es who cares as the dump pipe will be sectioned off :laugh:

      Driveline vibration is resolved. I ended up loosening all my engine mount and trans mount bolts, giving it a good shake then retightening everything and it's gone... Let's just say I was surprised that fixed it.  I've been happily driving it around again but unfortunately put zero time into my direct port/constant pressure WMI setup. I'm on vacation next week, so I'll try and finalize it then.  On a different note, I spent all week fuel/ignition mapping 2x 216L V16 engines. Turbo's were burning glycol and we swapped them out for larger units. We also had planned emissions testing on site, so I figured I'd be there the same week to use their instrumentation and massage any emissions issues out if needed. This was a first for me. Fuel management is similar in certain ways to automotive (i.e air density as load variable) but very different in others. It's all PLC based and AFR's are controlled by air and not fuel. They use a control valve between the turbo and air manifold to control pressure which in turn controls AFR's. Due to this, target AFR tables supplied by the OEM are in pressures and not mass which really through me off. They use air pressure vs fuel pressure tables. I also relied on an O2 concentration sensor the emissions team had in the exhaust. Ignition timing was also all over the place and we were losing a fair bit of power. They're now happily sitting at 16-40BTDC depending on load. We were making about 1600kw at 900rpm at 90% load. Engines were running a lot smoother as well.

      Oil pan for RB25DET NEO Stagea "version"

      meh, it was a good video, clear about the issue and how he dealt with it. A bit heavy on the RTV and very brave to put an RB in anything without rebuilding it first, but otherwise I thought it was good Dose, I'm not sure that having the pickup forward is a big issue; yes of course the oil could shift under brakes but the sump should never be empty enough for that to be a problem (unless you also have a higher volume oil pump, and that oil can't return from the head to the sump quickly enough)

      I can donate $100 to your upgrade fund. So long as you can donate the IC7 my way....

      I'd love a Haltech ECU, and Haltech 10 dash. Was having a chat with Rob and Andy @ Haltech when Rob put one in his MR2. First one I'm kind of interested in too, as you can dim it RIGHT down. Andy was saying bright dashes is one of his peeves too!
