Not sure if a 20 would spool a 35r before 6 grand waste of time

I am not here to say a GT3540 is a good idea but here is Legend01's RB2.1 GT3040 (so GT35 compressor GT30 60mm turbine).

Clearly makes boost early enough.

That's a lot of boost and power pretty damn early on an RB20, do want!

gt3540 was making full boost by 4500rpm on my dads old r33 skyline, on an rb20 it would be almost undriveable i would think.

Legend went to a bit of trouble to get it there including extrude honing the turbo and manifold. The turbo is sitting in my garage atm. The car made more power than that dyno showed once a few other issues were sorted.

A GT3040 more responsive on a RB20 than a RB25?

Similar results on two DD dyno's. All to be found in the RB20 >260rwkw thread from several years ago.

RB2.1 HKS cast manifold, GT3040, cams from memory 260 deg, stock valves, ports tidied up, port matching.

Post with actual mods

If you scroll back a page there is another dyno print out with a high AT reading (correction??) but you get the idea.

Pretty impressive IMO especially from a little 20. Would be a fkn quick little car looking at that dyno sheet

What are you complaining about? Your first question was answered - yes the intercooler is far too big and the stock one would work better.

You suggest you are going to get a 35/40 - you are told that is also far too big which it is.

Then some people helpfully report how with a lot of supporting work a 35/40 can be used to make big power on an RB20.

Look past the scoffing at your inexperience (we were all inexperienced at some time) and you have got the answers you need.
