Hi all. as the title states, I am new to the forum but not new to the car world.. This is, however my first import.. I had a buddy a couple of years ago picked up a 2002 is300 with the aristo swap done, singe precision 60 mm turbo, aem ecu, rotora 6 piston big brakes, hks intercooler and electronic boost controller... it was to much more him... so I took it... it came with a dyno printout saying it made 440whp.. the car used to be auto but is now a manual.. for the most part the car is sound, and drives well. it has tein coilovers, it does have a couple of issues ... nothing major. small oil leak on the filter adaptor, needs an alignment, and there seem to be a couple of vacuum lines that aren't connected to anything... lol.. I look forward to picking your guys brains as I bring this car up to snuf. unfortunately, I do not have a build list for the engine.. all I know is it has arp studs for the mains and the cyinder head, hks cams, (don't know which ones) ... that's it.... it does seem to be tuned really rich... wondering where I should go from here... turn the boost up? dyno tune? thanks.
