Hi
I’m in the market for a topmount manifold and turbo for my rb20 does anyone have any recommendations and to where to get 1 from as I’m struggling.cheers
 
Best bet would be to get a custom one mate I think dude! Try apw engineering just had my manifold made by him! Only ever seen good things! As well as it having lifetime warranty

It depends what route and turbo you go down mate...
mines a twin scroll Hx35 turbo and has a true twin scroll manifold design plus 2X external waste gates all in delivered think it cost me around £1400 but I think without the gates it would have been around £900-£950 worth it if you plan on keeping the car and running a reliable set up imo
 
Sinco, 6boost or Walton are the only 3 I'd use.
Hoslets are awesome make plenty low end torque and responsive.
Have a look for an hy35 11cm

Well its actually rb30/25 in r33 but that doesnt really matter in this case. Running a he351(w) holset with a 14cm rear housing at around ,550hp/730nm. You can find more info and dyno graph in the holset thread :)
