240SX's have 160 lbs of TQ...not 140...the torque is what makes them liveable

i think if you learn how to launch the MR2 you'll be very surprised...

the low end tq means shit esp compared to a mr2 turbo, those things make 200 lb ft of tq at like 3000rpm. also they can take off like a bat from hell from a stop.

hondachili is one of my best friends. i raced his mr2 a few times and from a roll we are almost identical and i'm making almost 290 crank hp. so there is nooooo waaay in hell that your stock almost dead KA would even stand a chance against a mr2 turbo unless the engine on that mr2 is dying worse then yours and is already blown.

hondachilis mr2 has a exhuast, and a gutted intake. thats the only power mods he has and it raised his boost from the stock 10 psi to 13 psi without any boost controllers.

Wow.... have you ever seen a dyno plot? My turbo kicks in at about 3krpm, which im never even at during a drag race, and more importantly at those RPM the MR2 isnt making anywhere close to its peak power. So how would you know what HP rating its at, at 3krpm?

No they come with bypass valves which are 2000% thats right 2000% better than a blow off valve.

This is also the reason your friends car may not be as fast because the metered air is getting blown into the air not back into the engine which will mess up the ECU's settings.

I raced a 240 in my MR2 and by the time i got to third he was so far back i couldnt see him.

A N/A MR2 would be a close race as they can also launce high.

Also the stock MR2 hasa twin entry turbo wich allows for 200tq at 3300rpm that turbo in my car pulls quite hard in high RPM.

Your friend should have his car checked out the vacuum lines and replace the factory Bypass valve.

Also new plugs wires and rotor from toyota should be replaced.

guessin he figured it'd be like the N/A or something? besides the gen 2 engine produces its peak torque at 3200RPM which isn't particularly high so it's still got enough torque below there, and ditto, who drops below 3k in a race anyway?

The 3S-GE/GTE has plenty of torque down low. One of reasons why I like Toyota so much is how hearty and solid all of their cars feel, and this is mainly because of their tough and torquey four- and six-cylinder engines.
