Thanks Mikey, just looking around if it's cheaper elsewhere!

What bhp would you get from a standard CTSC setup (ie. rising fuel pressure regulator from CT)?

I'd like to go with an AEM EMS straight away, but with mapping that's another

Stick with the Comptech, Itchy.

I think you are looking at about 50 bhp with the standard kit.

Doing it in stages is sensible IMO.

I just didn't like the idea that there may be issues with the fuelling with the FPR.

I'd look in the FS forum too, but i've never found one preson willing to ship anything to the UK

Thanks Mark,

I was hoping to find one on the US boards for sale 2nd hand!

I'll have to keep my eyes out!

On another note -

How much difference does a cat back exhaust make on an S2000 with a CTSC? I did have a Scooby and an exhaust made a hell of a diference. Is that the same with the S2000? Anybody know by how much?

on my vortech setup i gain 19.1 peak hp and 25 tq in the mid range!!! i got a custom 3inch single.

Itchy, it's not the same as decatting a turbo, but reducing back pressure can only help.

Downpipe on a scoob is worth around 20-30 bhp.

I doubt on a UK dyno it would get that much if it was the S2000

Itchy Dick

That's quite a gain!

Indeed - US dyno

Itchy below Dyno from mine on a stock CTSC + AC install (bar the Mugen exhaust)
320 BHP from 243 BHP
Problem is if you do ANY mods teh stock set starts to lean out and can cause major problems!
I've run that stock set up for ~5k miles no issues.
Once you decide to up it from there you can easliy start spending the same again
Header, decat, exahuust, injectors, pulley, AEM EMs tuning, better rad, oil cooler! etc etc!

Before and after on the same dyno same operator!
