egr valve + intro Sun, 23 May 2004 12:59 Go to next message
Hey everyone
im sort of a newbie here,but i guess ive been more of a reader than a poster of toymods. Well anyway i used to won a ae82 twincam, until i got hit from behind at 110 from a XA GT falcon (i think so anyway?) and write off the car on Christmas eve of last year. Still inspired by toyota's Razz i went back and bought a Celica st 162 with a gen 1 3sge!

Now to the question, the 3sge contains a egr valve and reading around other forums im baffled on whether or not to block its recirculation into the intake. I am wondering if anyone has done this before and has it increaded performance, fuel economy, etc????????? any info is appreciated in advance

thanks

Fuel economy down, emission toxicity way up.

Performance...maybe a few kW depending Smile

That's the basics...and any fooly sik dweeb saying that blocking off the EGR on a stock 3S-GELC will raise your performance noticeably is clearly either drunk or high.

Read Robert Bosch's book on carburettor and EFI tuning.

(edit : tired english)

ok thanks for the reply...err i dunno if i should class my engine as totally stock. Since ive had it ive given it some 10W-40 semi synthetic oil, advanced the igniting timing just a touch, cold air induction, and at the moment am currently getting a xtreme streetwise heavy duty clutch installed and whilst its apart,im getting my gearbox strengthened and repaired ( due to the worn synchro's)

Im also soon to be giving it larger leads NGK iridium spark plugs and a k and n panel filter. Will it be worthwhile?

ohh well if anything ill see what its like for a day or so
thanks again for your comments!

By non-stock I guess I usually refer to when the flow characteristics of the engine have been changed (things like cams, porting, exhaust etc).

You could take this stuff off...but it will have the same effect as stated before. Getting kWs is all well and good, but making the car illegal on the roads and completely screwing the emissions up is not.

It's really just a personal preference. You can go for it, but it's unlikely that you will atually be able to notice the extra power, on a car as heavy as the ST162, you really need to add at least an extra 8-10kW before it makes any noticeable difference.
