Ted Posted March 21, 2013 Report Share Posted March 21, 2013 Looking for suggestions on tasteful upgrades for an S52 without going supercharger and or turbos. Looking what can be done to the motor to achieve maximum HP and performance. Quote Link to comment Share on other sites More sharing options...
Guest Mott Power Posted March 21, 2013 Report Share Posted March 21, 2013 3.38 or 3.64 diff swap and an individual throttle body setup would be what I'd center the project around. After that then look at the usual exhaust and intake modifications. Quote Link to comment Share on other sites More sharing options...
Brian. Posted March 21, 2013 Report Share Posted March 21, 2013 Chipped, tune, bolt ons, header, intake, etc. Quote Link to comment Share on other sites More sharing options...
Ryan... Posted March 21, 2013 Report Share Posted March 21, 2013 Lots of guys on Bimmerfest running ebay headers, various exhausts from the headers back, chip or tune (trm is popular), and they're seeing about 215rwhp. I'm sure you know, but without FI you wont be getting much more power out of those motors. Guys are spending $4k to get 250whp on a N/A setup.

Rowleym Posted March 21, 2013 Report Share Posted March 21, 2013 I say best upgrades are suspension+ light weight stuff such as wheels and other rotating mass.. B C 1 Quote Link to comment Share on other sites More sharing options...
Earl Posted March 21, 2013 Report Share Posted March 21, 2013 Suspension doesn't make the engine faster rowley. Lol With it being obd2, you need a tune. I highly recommend Midnight Tuning. I absolutely love my 93 octane chip. A lightweight flywheel, underdrive pulleys, headers, and m50 manifold would get you sitting good.

wasnt m3 Posted March 21, 2013 Report Share Posted March 21, 2013 Don't forget cams! Gotta spend a ton to make good power n/a. Quote Link to comment Share on other sites More sharing options...
Ted Posted March 22, 2013 Author Report Share Posted March 22, 2013 As for now I would like to just focus on the engine. Clutch and flywheel will be address separately. I will be doing a rebuild and want to do as much as possible to maximize the BHP . Some items I was thinking was 1-Cams : which ones ? 2-Shaving head for higher compression ? 3-Enlarging and polishing inlet ports on head ? 4- OBD 1 manifold upgrade 5- fuel injectors upgrade which ones? After that I was thinking to flash ECU with upgrade software such as DINAN stage 2 Then comes all the bolt ons. Ted Quote Link to comment Share on other sites More sharing options...
Earl Posted March 22, 2013 Report Share Posted March 22, 2013 Dinan usually does a great job with their products, but I don't think their tunes are their strong suit. Like I said. I highly recommend midnight tuning. You can tell him exactly what mods you have, what fuel you run, and how you want the rev limiter set at and he will flash it for you.

Brian. Posted March 22, 2013 Report Share Posted March 22, 2013 I'd go with what earl's saying. Get a custom tune. Nothing is better then a custom tune. Especially ones that can be made to the 'T' with what exact mods you have done to it. Quote Link to comment Share on other sites More sharing options...
e36mpwr Posted April 5, 2013 Report Share Posted April 5, 2013 What tune are you guys talking about I'm interested sorry for the noob question. Quote Link to comment Share on other sites More sharing options...
Earl Posted April 5, 2013 Report Share Posted April 5, 2013 A chip for an obd1 dme, or a reflashed obd2 dme. I love my chip from midnight tuning. Quote Link to comment Share on other sites More sharing options...
