Hey guy's im intrested in slapin in a 6 speed box out of the 34 into a 33, im doin a engine upgrade and am just tryin to get some idea's on which direction i should head in. I'm going for some good hp bout 500+ at the wheels will it handle this or should i go to a dog box?

Any help would be great thanks guys.

Have you thought about;

- IIRC R34s have different diff ratios to 33s so using the R34 gearbox with the R33 diffs may suck a bit (or may not - check it out)

- Will you need a custom tail shaft and how much will that cost

- Availability and price of aftermarket gear sets for the 6 speed compared to the 5 speed

- how much it will all cost and if its really worth it ;-)

Yeah I have had some thoughts about it, the tailshaft not a problem as im a fabricator and im allready rebuilding my diff so it's not that much of a problem, I just want to do something a bit different with my build any feedback would be good cheers

    • So for the wide band is a Bosch 4.9 correct for the Link G4+ along with a Can bus? Just get the Link gear or is generic ok too? Eg here: LINK LINK DIGITAL WIDEBAND CAN MODULE WITH BOSCH 4.9 SENSOR : KYP Performance House  
    • Bit difficult to follow. Have a look below and see what the standard R32 layout was like. Note there was a restrictor in place immediately before "turbocharged pressure control solenoid" that, if removed, magically got you 1 bar boost.
    • I might be way off the mark here.. there must be a T junction under the manifold. That takes manifold pressure through a check valve prior to the T, one side splits out to this bleed off orifice, the other straight to the wastegate actuators. 
    • Carrying out some engine due diligence before my first drive in a 260RS that has been in storage for 10+ years, and found two lines that are susposed to be plumbed into the boost control solenoid. One of the lines (the wastegate boost supply line) to actuate the gates, had a bolt in one end blocking it. The other line (main boost signal line) from the very rear of the intake manifold (RB26DETT) and runs up to the boost controller had this pill in the end of it as seen in photos. Other than the obvious (T28 Ceramic turbos might well be cooked)  Can anyone shed any light on if there is any validity at all with this mod, bleeding a constant fixed rate of manifold boost pressure off through this 3mm hole?  Is it deliberate?  Was this a 90s Jap mod done to RB26's? Or has someone just fitted this without any idea of what happens to ceramic T28s if they are not gate controlled?
