Thats good to know. I have a good friend who has an S2k and hes let me drive it on occasion. definitely a wonderful drive and as u said, more engaging. The evo just feels like its driving itself, and as a toy/project car, its annoying. Doing any mechanical work on the thing is beyond a nightmare. Ive come from an MR2 before that (people say theyre hard to work on? But in my experience theyre pretty simple). The evo is just insanity, the amount of work involved to remove that gearbox, let alone remove a turbo dump pipe haha. Funny times.

Anyways, ive been doing lots of reading on S2ks as my next project basically. But i think i should decide on my daily ride first and be happy with that...

 

I probably have the smallest turbo on this forum on my s2000 other than people with the greeddy kit. I'm running a garrett ball bearing 50 trim. The flow rate is only rated at 46 pounds per min. On my old mase manifold I was about to make 395whp at 11psi of boost on 91 octane and 501whp on 17 psi with e85. This turbo spool pretty fast. I use to have this turbo on my old rev hard log manifold and the log manifold made a lot less power but spooled the turbo much much faster.



Here is the boost plot


Here is the boost plot with the same turbo on my s2000 just with a log manifold. look at how much faster it spools than a tubular manifold. With the log manifold it makes crap for power but it spooled 800rpm faster than my tubular manifold.



Picture of my current setup with a Track Forged manifold.

 

pretty good spool. Even with your tubular manifold u get decent spool and a long powerband. Is that stock motor? any other modifications. S2ks look like pretty fun cars to get into. Im keen

 

I built an s2000 with a precision 5431.. a very small turbo.. it was on a 2.2 liter with a pretty decent custom turbo kit.

it hit 12psi at 3800 rpms, carried power pretty well to 8500.. it made 430hp/330tq. Very fun car to drive.

If you used a 28rs with the big t3 .83ar turbine housing it would probably make close to 400, but that compressor wheel starts to max around 350.

IMO a gt3071 with 82ar t3 turbine would be the best small turbo for an s2000.

 

GTX3067 seems like the ultimate street setup, though I never fealt like my 35r was laggy........
