And great story bud. Maybe one day you’ll be able to afford your own BMW! Bring that company car of yours over to LA if you want to a real comparison.

Mine might be a race car to you — modified beyond your pervue. But it only takes a $500 jb4 and the 320 is faster than a stock 328. After all they have the same turbo! Lmao. OP can decide for himself.

[sspade]

Afford. Ha. I make more twice the average American household. By myself. At 30.

Dont be jealous. Its pitiful.

Good day sir. Enjoy your 320.

Blimey a lot of arseiness, yes I know it's not a real word, in this thread.

No one cares! Lmao. TMI.

“Jealous”, “pitiful”... calm down bud it’s a car forum.

Maybe one day when you’re my age you will own your own company too and fill your driveway with BMWs like me. Maybe even afford your own household in LA where we can be neigherbors! Oh wait, nvm — I’m younger than you!

A real test of class and wealth is how nice you keep your car. I see you have some mods, post a pic of your 328i if you want to keep comparing dick size. I already know mines faster, but let’s see how nice your setup looks. I’m bored of the babbling, put your money where your mouth is and let’s see what ya got! You’ve derailed the thread anyways.

It puts car lengths on stock 35i as well. Forget ford fusions lol, what do you drive? I’m sure my 320s faster than that too. Come down to LA and I’ll dust your 328.

was the 35i parked?

I have to admit - this is quite entertaining

Lol no just stock. Pulled away on a 440i the other day too. Lil n20 that could. It doesn’t stack up against a similarly modified f30 335i, but a 320 fbo with jb4 and 100oct or ethonal is no joke! However, I was pretty even with a similarly modified e90 335i (fbo jb4 map 5). He eventually pulled on me as we approached 100mph, but I was ahead up till that point. A modified 20i or 28i makes a pretty awesome car for city driving where you never have the chance to go above 80. Plus it doesn’t guzzle gas! Especially if it’s the higher compression 320!

Did they know you were racing them or...?

I've heard of the n20s grenading with a lot of engine mods.. not sure if that's true.. I don't really want to argue over this lol but I guess I'm here to say: be careful!

Very true. Already blew the engine once f*cking around. You have to know what your doing. The 320i especially can run lean and can’t handle past 18psi without the right supporting mods or octane. But with the jb4 you can read your logs and find the sweet spot. People are starting to do it right lately — I’ve seen some pretty impressive psi levels from dudes in the n20/26 forum here. Most are from other countries where bmws are far more expensive and they’ve learned to exploit the hidden power of the 320.

Purely out of curiosity, what octane do you have to run and how's the availability for it?

I run 91 octane map 5 daily and it’s a light car so that puts you at around 335i/40i performance. If I want to do map 2 and bump the boost from 18 all the way to 22psi then I found 100 oct or an ethonal blend works great. A meth kit would be an awesome fix too. The e90 335i I raced was running 91 on map 5 as well at the time. And when I raced the f30 335i and 440i I was in map 2 with 100 octane. I used to daily drive map 2, but after blowing my engine once, I don’t chance anything outside map 5 without high octane. If I had 93 octane I would probably push it though. Just look at the ignition timing on your logs and see how it behaves. The 328/35/40 are going to be more accepting of lower octane. Map 5 however is specifically designed for the 320i and is quite safe even without supporting turbo mods.

ok I knew I wasnt going crazy haha

Why dont you go flash tune and use the JB4 as a boost controller?

Hell yeah! That’s the call. Just need to find the time and the right flash tune. I’m thinking Bootmod3 + jb4 and a meth kit. My buddy has been trying to give me his pure turbo stage 2, at that point I could swap it in and call it a wrap on the build.

gotcha. never big on jb4.. good luck!

Thanks! While we’re on the subject, got an ecu tune you would recommend?

I have an RKtune stage 2 tune which I love..but I'd say the most popular one on the forum is BM3


Cant go wrong with either

[satish_141]

all I bought a 320i as I cant afford a 328i. 320d I know has better torque etc but what we know I diesels now I didn't want a diesel.

Anyway my manufaurars warranty runs out in a years time, then is it a good option to consider ECU re-map?

320i still pulls well in manual sport mode....after 3K RPM...I love the drive...but still want more power if I could but dont want to take too much risk..

current 184 BHP even if I can get 200+ I would be more than happy I guess..any suggestions?

Pretty much no risk: dinan stage 1 (will get you roughly stock 328/30 performance) they match bmw with a 2 year warranty

Low risk: two good routes here. Use jb4 in strictly map 5 settings. It’s an adaptive tune that reacts to conditions and avoids risking pushing the engine too much. On a hot day it will adjust the asettings automatically). It outperforms the dinan’s piggyback platform. It’s the forum favorite and you can swap maps and raise the boost beyond. It also allows for data logging to check in your car, find problems, tweak parameters, etc. Supporting bolt ons will add more power and safety. The other route is to do an ecu tune. It isn’t just a boost controller, it’s literally a remapping of the engine and turbo. You can go for a mild or an aggressive bump on performance. You can also stack the jb4. (That would be the best set up!)

Higher risk: any tune without data logging capabilities is kinda sketch imo. Using any map on the jb4 other than map 5 is gonna involve some risk. FYI the great majority of people here are going to be using the jb4 on their 328s and that is not the same. They will be using the fixed boost maps 1 or 2. Map 5 is both safer and designed specifically for 320s and does not do fixed boost. So this is where the jb4 starts to get riskier. And more of the reference point your gonna get on the forums. That being said, use the right octane, check ur maps, get the supporting turbo mods, and you’re gonna eliminate a lot of the risk. Many many many people do it without issues. Just do it right and be prepaired.

My perfonal recommendation— jb4 / map 5 / catless evolution racewerks downpipe / and the cherry on top would be a larger intercooler if you really like to push it, go to the track, or even if you simply live in a hot area. I have like every performance mod save for an aftermarket turbo, and I can tell you map 5 is amazing. It literally adapts the settings based on your set up. I only bump up to higher maps if the octane is available. Lastly I started with dinan and switched to jb4. Would rather have the data on hand and better more customizable performance. The thing can be taken out, hidden, set to stock settings, etc, so it’s an easy one to hide during services, or just if you want to tame the beast for the 16yr old vallet bro.

Good luck!

Bootmod3 you can run up to 22psi with FBO stage 2 mods with 91oct. My dyno chart can get to 234whp max power. But gasoline at my place is very bad so i am planning a methkit but not decide which brand yet. Snow performance, Aquamist, AEM all are good and cheaper than jb4+bms meth especially jb4 will only be used as a controller.

That sounds pretty off. Targeting only 17 psi in map 5, can make around 270hp with no supporting mods and just a jb4. 22psi should be putting you above 300hp. Sounds like your setup is targeting the boost too high and causing you to run lean. A meth kit will help immensely, but you should definitely target below 20 psi on your current set up. You will go a lot faster and your less likely to damage your engine.
