any takers on this? last night i hit 165 in the '03. i had 1300rpms left b4 fuel cut so i think i can get 170. BTW this is on stock cams. of course my turbo looked like i pulled it out of Episode 3's lava scene!!! car was still pulling & the gauge was still reading 20PSI. with a 4G64 block, new ECU, & a 25G, 200mph should be around the corner.

 

you will need a new tranny/ diff gearing, i went 155 @ 6k rpm's in 5th, 170 is def doable w/ enough road.

 

i have done 175 in my MR before(at least thats what the speedometer said). and it was still pulling. and i have still have the stock turbo

 

You can hit 200mph on the stock turbo. the turbo is not what limits your top speed. CD and gearing is more of a limiting factor. ASTROEVO has hit 191mph and I'm almost positive he is still using stock turbo.

 

Damn, 191 mph on the stock turbo. Thats awesome....makes me love my car even more.

 

All on a closed road course, of course... :P

 

do u guys have your speed limiters removed??? Does teh reflash remove it??? it must because I just hit about 155 mph but i have 19" rims with 235/35/19 tires so if you do the math thats a lil over 160mph but stock the cars are governed at 156 mph from what i hear.

 

i went 165mph on open highway at 5900rpm
with stock turbo

 

the flash gets rid of it

 

i guess i'll need this gear set to lower my final drive ratio to 4.111...

 

TRE also makes a much longer final drive just so you know. Depends on what you use your car for but they would be another option to go with.
