1997 Eclipse GS, supercharger, Yes or No?

so, Stewart, what's your opinion about nitro on n/t engines?

you risk clutch and tranny, that's the way it is, but taking it into accout, may it be a reasonable way to have some extra power just when you really need it?

So getting lets say .. hi flow fuel injectors, hi f low fuel pump, fuel/air modulator, new headers and exhaust system, getting a new air intake system. Would that help increase response time and increase some power? And what about an electric supercharger, will that help at all? Pretty cheap and supposedly adds somem hp.

All very nice, but it is the engine management system that defines what the engine will do. The standard intake manifold is pretty reasonable when its clean. The MAF (in the air filter can) is restrictive, so a better intake pipe system will help. The valves are big enough. Exhaust flow and the std rear muffler is the main restriction, so put on a set of headers and a 2

1/2" system with a high flow cat. This will be good for about another 10 hp, and a freer revving engine == reduced response time. So the std 135hp 1G 4G63 DOHC engine will pick up to about 145-150hp

Replacing the std ECU with a MOTEC (or similar) and configuring on a dyno will bump the n/a 4G63 to around 160hp or so. Bigger injectors will be good for another 5-8hp. Update the cams to a sportier profile with more overlap and higher lift, and again configuring on a dyno will bump a 4G63 up to around 180-190hp, BUT the power will come in later and low end drivability (ie torque) will suffer.

You won't need a hi flow fuel pump until you put in a big turbo and big injectors. I use the std 4G pump in my Summit GTX 4G63T and its done everything I've ever asked of it. I will put in the 1G pump next time I take the tank out.

Complete waste of money in my view, because the "boost" is only slightly linked to ECU control parameters. In any case, 1-3 lbs of boost is of minimal use. A proper turbo setup runs at about 12 lbs.

Okay this is the kind of information I was really looking for, very helpful to me. I appreciate ur guys help that have given in input.

I went to the motec website and looked around. I'm not sure which of the ECUs I would need.. I see a couple that match what my car is, but not sure which is the best.

Sell it and get a 04-05 neon srt-4 ...0-60 in 5.3 sec ,top speed elec-gov limited 153mph. ALL In STOCK trim 230HP @ the wheels and 250 TQ . you can find a low mileage one for about $13,000-$17,000 (ebay). And if its a 05 it'll still have some warranty left.
