1998 Mercedes C230 (Non-Kompressor) Custom CAI using Spectre components. Not a ''short-ram''.

Something new? Not really. Few people tune the NA 230 though as the 280 and 230K are better places to start.

Wow, awesome replies guys, thanks Zmatt about the turbo info. I was planning on just buying a second engine (M111 Kompressor) and just replace with OEM rods w/ ARP bolts and some JE or Mahle forged pistons. Basically just a refresh, probably skip the headwork as far as porting and cams...just replace lifters and add better valvesprings.

Yeah I figured i was gonna hear that hte stock ECU is crappy lol, I would go with HALTECH over any other standalone, just personal preference. I'm just not good at making the adapter/loom harness, that I would need someone to do for me and I would def pay well for it to be plug and play.

Yeah I have my heart set on a GT3076, with custom log style manifold(reliable N cheap), swain tech coated, Tial WG and BOV. etc etc...

Injectors, i'm not sure about which ones to go with. We have 93 octane so whatever safe limit on pump gas would be, no race fuel or methanol injection.

Like I was saying, a goal of 275rwhp would be plenty, which is roughly 325hp flywheel using 15% driveline loss.

Uber responsive and fun to drive, while getting 30mpg!

It doesn't quite work that way. You wont get 30mpg with boost. The only way you will manage that is if you tune it so boost only kicks in at high revs, or if you use an ECU with multiple maps. The first will give you all top end and turbo lag which wont be good, the other means you will have to get a standalone which I recommend anyways. Also low boost will be inefficient on a GT30. If you only want 275whp you may want a GT28. Garrett recommends the GT3076R for 310hp applications and up. I don't see the point in that low power anyways, congrats you spent more money than the cost of a C36 to go as fast as a C36. Go big or go home dude. If you aren't out running a C43 it isn't worth it. I'll say that up front.
