Is200199 0 Posted December 20, 2020 Share Posted December 20, 2020 Indecisive if to modify my oem 99 is200 sport.. want more power but almost impossible without spending a small fortune from the learning ecu to the fact the electronic TB is a d£&k and does what it wants.. throttle response is let’s say.. non existent.. anyone got any advice on improving the dated tb ..I’ve heard about putting the jzx Tb on but standard that throws engine management problems in the mix.. being honest the uk IS is meant to be a bmw beater not a B road basher like the Jdm altezza .. just seems like the platform has a lot more to offer.. love the car .. a lot of car that everything works on 21 years later, Lexus ought to be proud 👍🏻 Quote Link to post Share on other sites

scudney 308 Posted December 20, 2020 Share Posted December 20, 2020 Why even bother on a 21 year old car except you are going to do a rebuild and have a fair bit of money to spend etc Quote Link to post Share on other sites
Mossypossy 124 Posted December 21, 2020 Share Posted December 21, 2020 If you want to modify a car then start off with a turbo powered car. Easy gains to be had. I upped my Saab 9000 from 225hp stock to around 300. Could have gone above 400. If you want Japanese madness get a Supra. Quote Link to post Share on other sites
