so guys basically ive got an rb20det with hiflow r33 turbo, full 3" exhaust with stock cat. no boost controller atm as im looking for the right sort. it has a jun tuned ecu which i was told through jun is removed speed limiter, raised rev limiter and modified fuel ratio. it has aftermarket coil packs and pod filter also. ive got a front mount going on next monday and im trying to work out basically what is needed for the tired 20 to push 300kw. i know it will probably need a bigger turbo set up. im currently in the market for gtr injectors before i raise the boost.

so what shall i do? anyone have any 300kw rb20s? how do you do it without to much muching around. im also aiming to try get things compatible with rb25 for when that day comes.

Why did you post this here?

1. you'll "probably" have to change the turbo? haha. You'll need a big turbo to get close to 300kw from a 20.

2. If you do indeed want 300rwkw then I wouldn't even bother with GTR injectors 442cc is going to be too small.

3. It's going to make absolutely nothing before 4500RPM+ and not be very nice to drive, at all.

My tip? Start with an rb25 because you'll spend all the money you need to get buy a RB25 and get it to 300rwkw to get the RB20 there and you'll just be disappointed.

If you are happy with 220-240rwkw, then that's the max you should try for on an RB20.

      My BMW E39 528i touring

      Like a Stagea, but not as cool! Hope you have enough garage space for this, or is something going to leave to make way for it?

      My BMW E39 528i touring

      By PranK · Posted

      The new project has arrived. I have wanted one of these for such a long time, well before that meathead Clarkson drove one in Africa. I really wanted an E34 but I have some medical issues that mean I *really* can't bump my head and the lack of airbags in the E34 made it just too big of a risk.  I don't know why I've always liked these older touring BMW's to be honest, but man I love this car. She's been pretty well maintained for her 243k's with what appears to be only a single oil leak at the oil filter housing gasket. It has a bunch of updates including later model bumper and headlights, 7 series billion-way adjustable seats and it came with a few spares and another set of wheels with legal tyres. I got a unregistered car permit from the RTA and drove it back from Canberra on Saturday.                   First cab off the rank is cleaning it up for blue slip. I dont know how picky they'll be but I figured I'd clean the headlights, fix the oil filter housing gasket, replace the speed sensors (throwing errors) and swap the OE wheels (the M Sport wheels have a big chunk out of one of the tyres.) I also need to replace all 6 gas struts - 2 for bonnet, 2 for hatch and 2 for hatch glass. The car tries to eat me whenever i open any of these. My plan for this car; Ultimately, this is a budget car. I can't afford to throw lots at it and its because I have another car that I got this, if something breaks its no big deal. I will just maintain and repair it really. But eventually I want to do a manual conversion. It actually looks pretty straight forward for E39's and the trickiest part will be sourcing the parts.  I do need to replace some suspension arms or bushes because wow, she's a floaty old girl. She's also fantastically slow. Like really, really slow. When pulling back out on to the freeway on Sat after a quick pull over I needed to wait until no cars were visible before going.  Oh, and the guy I bought it from had a gorgeous R31 GTS-X in the garage.

      R33 gtst gearbox top barb

      By Duncan · Posted

      Do you have a picture? I assume it is a breather for gearbox oil as it expands, it should have a vacuum line run nice and high in the engine bay (R32 GTR has it on a top bellhousing bolt)

      By zigrb30 · Posted

      Hi all, I am putting an r33 gtst gearbox into a VL and have noticed what looks like a vacuum barb on the box (on top in the middle). Suspecting that it's a vacuum line but I'd like to double check, if someone could confirm the function of that would be great. Cheers in advance.

      I’d love to find some where that can recover the dashes to look brand new and original. Mine has a very slight bubble, nothing compared to some I’ve seen though
