You do realise, don't you, that in the sequential setup both turbos run together anyway after the transition, ie above 4500rpm. Somebody on here experimented...
Yeh, I do thanks. Using a primary housing with a secondary core is actually the best method, hybridising the primary in this way produces the quickest response...
Hi i'm new to the Group and am looking for answers to help me decide whether or not to buy a 1999 GTB that's for sale locally here in Malaysia. It's a 2.0L...
Hi Brian, You really need to take the car for a drive. Firstly, scan the archives for references to "VOD" and what it takes to avoid it. Check for oil leaks...
I have a 1995 GT Twin Turbo Manual Estate, I have been using a mechanical boost controller for about a year and have decided to return the car to 'standard'...
ECU reset? Not sure how your setup worked because mine seemed to only work with the standard boost controller in-line with the mechanical boost controller. I ...

Jeffrey,With the original pipe there is a restriction pill in the turbo outlet side of the tee,If put on the wrong way you will get only wastgate actuaor...
Thanks Steve, Okay that certainly explains the power graphs i've seen and the reason i've seen some go from a twin to single turbo. Know anything about the...
Wayne, Fantastic advice !!! This is exactly what the problem was, turned the pipe round and 'normal' boost has returned nearly ! The system is now oscillating...
Hi Brian, If I recall correctly, the D revision (BE5D as opposed to BE5A/BE5B/BE5C) had uprated rear links which did make a significant change to handling to ...
Guys, very interesting reading. As I had similar problems a while back, they seems to have been fixed once the piece from the prim-wastgate to the T were...
Adrian, if it is the same as my MY02, there is no number. The restrictor can be felt if you squeeze along the hose between the "T" and the turbo outlet side....
Adrian, The hose number coming off the T piece and between the T piece and the waste gate is 23. There was no number on the small piece of pipe between the T ...
Thanks Steve for your replies, most helpful. I've just placed a deposit down on a white 1999 B4 with 42k kms on the clock. Comes with 18" rims (wet sand...
does anyone have a service guide i.e. 5000miles with suggested times for cambelt etc as information is hard to come by for my 2001 b4 rsk? Has anyone tried the...
Hi Brian, It's been a hotly debated subject but here's my take on things. A larger exhaust after the turbo will reduce backpressure on the turbo and help it...
I had the ecutek mapping for a 2001 GT-B done at Power Engineering and have done 70,000 miles on it (over 2 years) no problems much improved the whole...
Anyone have info on how to rid the B4 of its original back box and unleash the boxer burble? Cant find info on whether or not an Impreza unit will fit or if...
There is a lot of choices (within Japan). Not sure over there, though I'm sure we could mail AVO goods that way. ;) How specific is the emissions there? There...
... I can thoroughly recommend Hayward and Scott. I just fitted a stainless centre pipe and back box to my GTB - took under an hour (most of that was getting...
I would agree with you on the 280bhp twins being a bit more jerky at low revs. You have to adapt your driving style to use the clutch a lot more when crawling...

Hey all, Simple question - I am trying to get a 96-ish twin turbo engine running in a different chassis. The expansion tank on top of the engine has a couple...
Yes, 'friad so. I'm doing too many miles in it and now fuel costs have

I think there are the following connections on the water tank.
Pipe from turbo.
Pipe to the metal pipe sticking up from the head area
Pipe to top of radiator....
Sorry to hear that Spen. You've done a heroic job on the reverse engineering of the ecu. I hope that gets put to some good use somehow. It can't do any harm to...
