g60inca 0 Posted January 7, 2010 hey peeps! i have a g60 corrado running 14 psi of boost. it has a 68mm chip and pulley kit and a few other mods. i wana go to a 65mm as id like to get it to 17-18psi :D . il be upgrading the injectors at the same time but wondered about the map sensor, as ive read it only holds 1 bar (14.7) psi of boost? any ways around this? im still running boost recirc. at the moment if that matters. cheers Quote Share this post Link to post Share on other sites
JMC 0 Posted January 9, 2010 Standard setup should bleed away anything that you gain over 1 bar. When I went from 68 to 65 I didn't notice much of an increase in peak pressure, but it definately came in earlier (I was also using a flowed head so my peak pressure didn't get about 12psi anyway). If you want to modify the ECU, then that can be done - you can fit a 250kpa map sensor as used on the Rallyes. Quote Share this post Link to post Share on other sites
g60inca 0 Posted January 9, 2010 yeh it does pull well with 14psi, i mite just head down the new cam/injectors route, make bit more use of the boost. Quote Share this post Link to post Share on other sites
Supercharged 2 Posted January 9, 2010 Best thing to do in this situation is to fit either a rallye ECU (rare) or a ported head. The head work is one of the best mods to do anyway on a G60 and the increase in port size brings the boost figure down. Quote Share this post Link to post Share on other sites
eddy.h 0 Posted January 9, 2010 bar-tek do a 250kpa map sensor you will need a new chip for that Quote Share this post Link to post Share on other sites
