5s-fe dyno figures Options

[deseptv]

Hi guys n gals,
Im in Australia and have a st204. I had it dynoed before i started doing too many modifications so i could get it dynoed later to see how much i will gain in power later. With a K&N panel filter and cold air induction it made 76 kilowatts at the wheels (or 102hp). Since then ive had a custom exhaust fitted and am about to purchace a APEXi SAFC II, so im hoping for a decent gain. My mate's VTEC Prelude made 107kw (143hp) so ive got some work to do =\ Does anyone else have any 5s-fe dyno results?

^There's your info. That site is a little better on tec info. I like it for finding stuff out about the 5sfe. Those 5th gen guys really know what's going on. I see you have an idea because you know the 3s head flows better. However, as you'll see from that post, the 5sfe bottem end is limited due to stroke. I should know better, but I'm trying to build my 5sfe too. I talked to a guy who did everything I'm wanting to do, and he eventually swapped a 3sge in his Celica. He said if he were to go back, he would have put the 3sge in there in the first place. More parts, more potential, everything better. The only reason to go with the head swap seems to be turbo. I've heard the 5sfe block is only good for about 6-6.5k rpms. For a real high hp NA, you'll need more rpms than that. Sad, I know.
