Tasteful upgrades for S52 4 Max power

[Brian.]

Chipped, tune, bolt ons, header, intake, etc.

[Ryan...]

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.

I say best upgrades are suspension+ light weight stuff such as wheels and other rotating mass..

[Earl]

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.

Don't forget cams! Gotta spend a ton to make good power n/a.

[Ted]

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.

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.]

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.

What tune are you guys talking about I'm interested sorry for the noob question.

[Earl]

A chip for an obd1 dme, or a reflashed obd2 dme. I love my chip from midnight tuning.
