I pretty much have all the basics that are available for my N52. At the top of my head I know I can grab a RPi GT exhaust since my exhaust is still stock. After that, is there anything else that someone can recommend?

I wish we had pulley and header options...

Thanks in advance

Yes, my charcoal filter is removed. I also looked into the OE tuning flash two weeks ago... I cant do that since I have to ship out my ECU. I DD my car at the moment.

325/528

Any Active Autowerke dealers near you? If your car is a 528, you can do the 3 stage intake manifold upgrade from a 530 and pick up some low end torque.

Here are some ?976,00 headers for the 525:

Given the limited SC/Turbo options for your engine, I'd explore the benefits of nitrous with a seasoned engineer if I were you.

You can do forged rods/pistons and a ground crankshaft, too. Some people will offer it as a service like these guys do for the N52: http://www.noellemotors.de/3_2l_engi...5cda0bd.0.html

Getting your flywheel lightened might be something worth looking into, though you may want to consult an experienced mechanic before doing so: http://www.racetep.com/flywheel.html

Also, it looks like Dinan has a high flow throttle body for your engine as well.

I can help you out with the RPI exhaust when youre ready. last time I checked the exhaust was in stock

Get the exhaust and contact Bruce at TT Motorsport to find out more about tunes

PS never mind about Bruce, he's not that close to you. But do enough research and you're bound to find someone nearby, who can hook you up.

Wow, thanks for all the information guys. I really really appreciate it

NeRwEEzy -- I'll be in touch. I need that bumper first though. Hopefully I'll be ordering it this week.

Also, I forgot all about strut bars for these cars. I could have been bought one of those...

check out the BMS powerbox. I have not personally used it, but it claims a 8-10hp/tq gain to the wheels. http://www.e90post.com/forums/showthread.php?t=321679
