Hi peoples,

ive been toying with the idea with a garret gt2876 with .7 front cover rated at 440 hp on a rb20 eng. I would make an adaptor plate to fit the standard rb20 manifold.The rb 20 is in a 180sx. Most rb20s ive seen with t3 flange turbos are very laggy.

Has anyone done this and how did the car drive?

Thanks Michael..

OK.

Any other ideas with t25 flange? im looking for between 220 and 240 rwkw with plenty of power around that 3000-3500 rpm. Previously i had a r33 that made 287 rwkw with a GCG internal waste gate turbo but couldnt run less than 17psi due to the flapper valve not being big enough. That eng made plenty of power down low and now going to rb20 is a bit laggy considering its only got a r33 turbo on it.

Michael...

Thats the RB20 for ya mate.

Have a read of the RB20 sticky thread

The the sticky "Forced Induction Guide" there is lots of RB20 info threads... but get used to haveing no torque. Its part and parcel of owning an RB20 powered car

sorry to say mate.. but its a rb20 if you want heaps of power around that rev range.. you might even have to go a 320hp GT25 by garrett.. but than your probaly looking at around 220ishrwkw (rough guess)

rb20's are wierd with turbo choices.. glad i never ended up modifyn my rb20 as the cost i could have spent on it ive ended up with a 26 with a few little mods instead but each to there own

    • By popular demand.. it was a coil. Got my hands on 1 new OEM coil, replaced with the one that made the less noise difference when I unplugged it while the car was running and started the car up. No stutter and the engine light was gone. I guess I’ll buy the other 5 they have lol
    • No, code 21 is very straightforward. It can only be the things described in that diagnostic flow. In fact it has no way of knowing that the spark plug resistance is out of spec.
    • Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.  
    • Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go
