mevsem Posted May 4, 2013 Report Posted May 4, 2013 Hi Marmes and welcome to best Greek club for the Mitsubishi Colt. Regarding you question, the best thing you can do is to visit a local exhaust shop in order to build your custom exhaust manifold. Bear in mind that fitting a bigger turbo means: Ιncreased fuel needs (pump-injectors) Νew down-pipe ECU remap The lads from R-Colt have reported the following after fitting the turbo you've mentioned: Spool Start (depends on the setup): 3000-3400 RPM Full Spool (depends on the setup): 4300-4700RPM Out of Steam (According to Feedback): REDLINE Max Boost: 1.5 BAR Max BHP: 310-370 (More info can be found here: Link - Use Google translation ) What other modifications have you made to your car mate? Regards, Ilias
Marmes Posted May 5, 2013 Author Report Posted May 5, 2013 Well, I found this interesting. I don't think it's so hard to do it. Jasma crankshaft costs something like 300 euros , conrods, depend on what you want, the pistons are the only thing diferent. They say on many sites that we have to use the 4g18 pistons. But I see that 4g15 piston diameter is 75.5mm and 4g18 is 76mm, don't know if 4g18 will fit for .25mm . If it did , it was needed was a forged 4g18 pistons with the right cavity to maitain the compression ratio, or changed if desired . Is there anyone interested in making forged pistons for 4g18 to fit our 4g15 engines?
