Hi guys,

Just wanted to run my mod list by you more experienced modders out there:

1. Dinan Performance Spring Set (1" lower springs)
2. Dinan Supplemental Ride Quality & Handling Kit
3. JB4 Stage 2 Tuner (w/Bluetooth module)
4. ER 4" Catless Downpipe
5. ER FMIC + ER Charge Pipes
6. Injen Air Intake

I'm not too sure about going with an aftermarket exhaust as this is a daily driver, and I'm actually enjoying a nice quiet exhaust after coming from a loud Chrysler 300 6.4L HEMI SRT8.

Thanks in advance for tuning in (no pun intended)

You're on the right page with your mods and I'm planning to do the same

I've done:
1. Dinan Performance Spring Set (1" lower springs)
2. Dinan Supplemental Ride Quality & Handling Kit
5. ER FMIC + ER Charge Pipes <-- i now prefer the wagner competition evo II as you can keep the OEM shroud

I may skip the Injen because I don't like the swooshing sounds and go catted instead. Would love to hear of anyone dyno'ed their car with the OP's planned mods

Have you looked at active autowerke exhausts?

Thanks anotheran

Is this the Wagner EVO II FMIC you're referring to?

http://www.wagner-tuning.com/NEW--EV...F30_p_194.html

If I can keep the OEM shroud, then even better! I want it as stealthy as possible

Ideally, I'd like to do the supporting FMIC + ER Charge Pipe + DP bolt-on mods before I go fitting the JB4 Stage 2 Tuner to run +4psi boost. I just want that added piece of mind that the IAT's are in check with the higher boost levels to ensure reliability and longevity. All it takes is some heat soak and some bad fuel and BANG, there goes the N20 motor

Might look into the Dinan bigger hybrid turbo too at some stage for more top end flow, but that'll be later down the track.

I'll take a look at the Active Autowerke Exhaust. Looks impressive. I just don't want the thing to be loud and drone on the FWY when cruising

Yup that link is the one. Good idea on doing fmic and charge pipe first. That's my route too.

I can't speak to the bigger turbos as I got the n26 engine.

I had a look at some YouTube clips of the Active Autowerke Exhaust and it doesn't sound too bad actually. Doesn't sound TOO loud. Maybe something I'll add on down the track for better flow and lighter weight compared to the OEM exhaust, and @ $599 isn't too bad

I'm not sure how much of a different the Injen Air Intake would make with the OEM Turbo, so maybe I'll hold off on that until I get the hybrid Dinan big turbo, which will no doubt require much more intake airflow on the top end. For now I might just get a K&N or aFe filter for the OEM airbox to support these initial bolt-on mods

cool - Seems the Wagner EVO II Competition Intercooler is also lighter than the ER FMIC, so I think I'll go that route too!

I'd wait for Bootmod3 flash rather than JB4 piggyback. I'd also skip intake and charge pipe.

Interesting, what advantages would the Bootmod3 flash have over the JB4?

Proper access to the fuel and ignition maps, proper torque reported to the transmission for better shifts, probably smoother part-throttle operation, access to hundreds of tuning tables. It's proper reprogramming of the DME rather than playing tricks on the data that the DME sees. Piggybacks aren't too bad of a temporary option for new platforms before flash tuning becomes readily available.

The JB4 is still king of the N54 tuning and flashing there has been around for years Flashes are good option as well. It really comes down to personal choice.

Back to the original posters question. Mod list looks good..

Someone mentioned to skip the Charge Pipe.. Even though the N20 has not shown as much failures as the N55, the BMW plastic charge pipe is a know failure point once boost is increased. It even fails on stock boost levels, so for the cost a CP is a good preventive supporting mod when tuning.

I have never heard of a single N20 charge pipe failure. The N20 stock pipe is stronger due to higher stock boost.

Nice mod list

[328iMSport]

Thanks guys, for your valued input and feedback

Can anyone confirm for me the weight differences between these components:

OEM FMIC vs ER FMIC vs Wagner EVO II FMIC?
OEM Downpipe vs ER Catless DP vs Wagner Catless DP?
OEM exhaust vs Active Autowerke exhaust?
OEM Spring set vs Dinan Spring set?
OEM Charge Pipes vs ER CP's

I mean, it's all very well and good bolting go-fast bits onto the car, but it's even better if you can reduce the vehicle's weight and increase HP in the process too!

That's another reason why I'm reluctant to fit larger 20" aftermarket wheels to my ride as they always weigh more than OEM Motorsport wheels... I might just get my OEM wheels painted gloss black once the car is lowered.

Curious, would there be any adverse affects to performance and emissions if a catted downpipe was used without a specific *DP tune* to match it?

I mean, would the AFR's be too rich or lean or anything like that?

Or would the only effect be I'd miss out +/- 3HP or so?

Emissions would be worse off. Performance would be a little better. AFR is closed loop and will stay exactly on target.

Thanks, bradsm87

Either way, it'd be better than the OEM restrictive downpipe?!

A teeny tiny bit, yes. I don't see any reason to go aftermarket catted downpipe. Both aftermarket catted and catless downpipes are both illegal so may as well get the best flow with catless.

Yep, I think I agree. Catless DP with a JB4 to supress the CEL generated from the DP.

Curious, any idea what "ball-park" crank HP can be had from a JB4 Tuner + Wagner EVO2 FMIC + Wagner Catless DP running on Map 2 setting (which I think is +6psi over stock)?
