Hi I'm Gary
I'm from Oklahoma. I have a 1974 BMW 2002 with a NA 2.0. I'm wanting to do some upgrades to get some more power out of it. What do y'all recommend. I'm putting a set of long tube headers on it and a performance exhaust but I thought about lightening a flywheel. Is that a good idea.

Hi Gary you seem to have a classic Beamer so I would want to keep it stock looking so Depending on how far you want to go I would be rebuilding the bottom end with forged pistons and rods that should be lighter and having the head recoed ,ported with larger valve with a sportier cam and the inlet and exhaust manifolds port matched.

Depending on how you intend to use the car for street use a 4 2 1 interference header of for track 4-1 with a mandrel bent system and straight thru mufflers.

Thank you for the feed back. So I'm kinda having a hard time figuring out this car. I have had it since I was 14 and I havent really been able to do anything with it. It has just set in a garage for year's and I have worked on other stuff. I'm used to building American muscle cars and hot rod trucks. But I really love my beamer its got that old skool rally car look and sound. And I like the offroad racing back ground and road course history of it. So thats kinda the set up I want. Leave the body stock and upgrade the rest to have that race car feel. Upgraded the suspension, brakes, wheels, tires, etc. But idk of anyone around here that messes with older beamer stuff to do my engine internals for me. Have any suggestions on what I should do.

IMO the basics of any piston engine remain the same regardless of type and it comes down to the prep and attention to all the little things when it comes to machining and assembly.

Any competent workshop that takes pride in the quality of their work should be able to rebuild your motor.

Ok thanks for the info. I'll do some digging on the engine shops around here and get the work done I'll have it port and polished and have the valves done bigger

Make sure that the block and head are hot tanked to remove accumulated gunk from the oil and water passageways and the crank counterweight ball bearings in them removed to clean out the oil galleries that will be there due to centrifugal force and have grub screws fitted in their place.

Have everything crack tested and make sure that the bores are torque plate honed as well.

Have the entire rotating assembly dynamically balanced and assembled with ARP Studs and bolts.

If possible replace the pistons and rods with forged items that will almost certainly be lighter as that will help response particularly in a NA car.

I would urge you to use Total Seal rings for better sealing and no/less blow by as well.

Just my 2 cents worth
