I have a stock lexus gs 400 ,and wanted to ask what. Is the smartest way to go,on performance parts,
I don't really want gears and stall,but has any one ,done a SRT stage 2 race intake and ecu,or the weapon R, also has someone done the kelford cams and springs?? And polished and ported heads, or installed other heads and cams?? I raced on a roll a IS 350 and I'm pretty sure with some parts ill get it, also I have read of someone doing upgraded injectors and coil hotpacks and muffler delete and claiming 12 .7 quartermile times, Thanks for your time!! Have a great day!!

 

Also with injector and hotpacks and muffler delete a computer ecu was reprogrammed !!

 

I would say Port & polish head is the best route i seen so far. I did the mechanical upgrade, my car can beat an IS350. There is a guy on here with port and polish and his times were the same with an ISF (0-60 in 4.3 sec, qtr mile in the low 12's just doing that by itself.. I'll have to find the Thread..

 

Found the thread.. Look on page 3. (0-60) in 4.3 Secs and 12.1 Qtr mile! This is what i plan to do to my car next and i have Gears/LSD, and TC.

Thanks ,I have been trying to gather as much info as possible its fun racing IS 350, even tho he has gears in the rear end and transmission and ther lighter about 300ibs

 

What do you think your ride is running?? Time quarter? Also are you running a srt intake and race ecu or a weapon R possibly??
