Hey mate, Both the same price...$1200+ Freight. This includes your choice of flange and one wastegate port. If you wish to have splitpulse add $100 and if you want two wastegate ports add $50.

Google is your freind!
Can't hurt to run both mate...you already have the other one so it saves changing it.
If not the 040 will provide stable fuel pressure to the 750cc injectors anyhow...basically up to you mate.
Matt
If your worried about it...run either an 040 intank which is bascially the intank version of what you have or a New Deatsch Werks intank pump would be great also. Just as small if not smaller than a Walbro and Flow 310cc per minute...
Matt
if you can't find anyone, use an "easy out" that you buy from the hardware store and DIY.
The new stud is referred to as an "Offset threaded stud", 8mm x 1.25mm threadpitch.

Sounds very much like a problem I had with a recent RB25 powered SIL80.
My problem turned out to be soft valve springs on the exhaust side...not cool.
Matt
Haha, his forum membership was enjoyed for all of 1 day.
I was like WTF this guys admin with no posts and been a member for a day....thats good going!
Matt
If it help's you out mate...mine recently busted off when I was putting my oil cooler kit on.
RB20 one's bolt staight up to the block, then you can just loop the coolant lines.
Matt
Sent you a PM mate. HKS say there no dump pipe listed as a separate item...but I can get you the flange which is the most unique part so you can get a dump pipe fabricated.
Matt
Sounds like a boost/vacuum leak of some sort.
I'm assuming you've checked everything is tight and not leaking? Silicone Joins/Intercooler Piping/Intakes/Bolt on the turbo housings...
