Looking to add 20whp in a cost effective, reliable way. I know enough of you guys have done it and dynoed the car, so let me know. I want to avoid the SC/Turbo route, and I know head work w/ems will do it but I'm looking at $3k.

I also want opinions on final drive gears, I hear you can have them bought and installed for $1k and gain .5 seconds in the quater????

 

20 whp is expensive.

I think you could do it with a good intake, maybe an enlarged throtte body, a J's manifold, decat, probably a good single exit exhaust and an AEM UCU with a good mapper.

More important than peak with those mods, is the fact you will get big gains throughout the rev range.

I think you are in the US so I would ask on the US forum. They seem to be able to get 20 bhp with an intake and a piggyback map

Supercharge it. Anything else will be a waste of money to get a large increase from an S2000.

 

The ONLY N/A mod worth doing is gears, bang for buck wise.

 

No extra horsepower obviously, but probably comparable in terms of performance to an extra 20-25bhp.

There's a Best Motoring clip which shows a 2006 car vs a 2000 one which has the 4.57 ratio final drive and the difference iin acceleration is remarkable.

 

Probably should have posted this question in the proper forums, instead of spamming 12 communities.

Merging does not work well, so, the CO's can do what they want with these thread.
