So recently I was looking at some youtube videos for some car ideas on what to do on my car. Since my car was the n52 motor in there I know I am not going to make crazy horsepower levels. With taking these ideas into mind I thought of the 335i and the 335is. Right now my baseline ideas are to make around 20 to 30 more wheel hp and 15 more torque. If you guys have anything in mind pls let me know. Also, I want to spend around 3000 for the mods and everything.

3 stage swap. It's like, $500. Skip everything else, buy Tesla stock and thank me in 10 years.

There really was no 328"is". Just a 328i with the sport package option, which did not change the horsepower. The sport package came with sport seats, sport steering wheel, and a lower, sport-calibrated suspension.

The 3-stage intake mod will boost HP to 260. Find the sport seats on line. Get a B12 suspension kit, and you'll pretty much have a sport package car plus 30 more HP.

There’s a really nicely documented thread about this exact topic in the photos forum...

Title is building the 328csl

Where would be the best place to find the stage 3 intake? Also should I new or used?

[tylerhart_21]

Also for an exhaust what do you guys recommend? (I am looking for the sound of the m performance exhaust)

328is was a theme for my build. There are 3 area you could focus on for a N52 version of a “is” and stay around $3k budget. This is how I would spend the money knowing what I do after building my car...

Power:

For power I would do a 3 stage manifold (used with valves for about $400), headers ($600-900), and a tune ($0 to $600). That’s about half your budget but will give you the best bang for the buck for the money and net 25-35whp. If you have a manual also pick up a 3.73 differential from an automatic and swap it in these can be had for around $200 on eBay.

($~1500 here)

Ride/Handling:

There are lots of ways to go but to stay in your budget I would do the Eibach B12 Pro Kit for around $900. I’d rather have this than coil overs priced the same I think the ride quality will be much better than cheap (less than $2k) coil overs

(~$900 here)

Braking:

Look for some F30 340mm Brembo front calipers and rotors. These parts are all a direct swap and calipers can usually be had as a set for around $500 used. Then you can replace the pads and rotors (only if needed) for like $400

(~$900 here)

Total Spent ~$3,300

Here is a post on the process with a link or two. Definitely people have done it for under $1k, since you're simply duplicating a factory 330i build on top of your existing motor.

It's harder to make a 335 into a 328is tho, that logic is flawed.

Lol so many people get butthurt by this but its the best option out there. A 335i make 280whp stock. Leave the engine alone and youll have a plenty reliable fun quick daily

oh look!

Dude, hardly anyone gets butthurt. This platform is over 16 years old. This is two generations old 3 series. Who gives a fuck.

At this point most posters who say dumb shit like this idiot are just trolling and want to cause disturbance. There is no contribution to the thread in any way. Do you really think that someone who got 328 did not consider 335? These cars are dirt cheap now. Heck, even e46 is getting more expensive than e90. Most 335 on the market now require shitload of maintenance, have severe issues that need to be addressed, or were abused to inch of their lives. 328's tend to be in bit better shape due to less complexity. Most have usual crap, but nothing too major. Leaky gasket here and there, but nothing crazy.

There are few of us on here who truly enjoy N52 for what it is... The last NA straight six engine produced by BMW. I would not trade my 328 for any 335. 340 on the other hand is different story.

[Smgs1992]

Clearly you did get butthurt lmao otherwise you wouldnt go off on a tangent. I wasnt even the original one to suggest it.
Its spoken alot because you get a bunch of people who dont do any research buying a 328i because its a bmw and after a few weeks they want it to be faster. They start asking dumbass questions like adding a turbo kit or is this $5k supercharger kit from ess worth it. Or you get people suggesting to spend about $2k on bolt ons that gain 30whp so it can make what 230wheel? If you truly enjoy your car for what it is that is fine no one is telling you its a bad car. Its great if you want to get back and forth to work and use it for a daily driver.

My contribution is telling the OP that modding a 328i isnt worth the money. He could sell it and buy a 335i if he wants a faster car. It isnt like he is going to lose much if any money doing so unless hes taken out a loan on it.

Ive had my 335i for about 4yrs now and guess what it has been perfectly reliable despite what you and every N52 owner would like to believe they arent breaking down every week and your car isnt some special godsend of a reliable bmw.
The only problems i have really had with mine are a couple leaking gaskets and a waterpump finally went out on me.
How do you know i wasnt suggesting a N55 anyway especially since i said to leave it stock.

Get off your high horse and stop acting like a damn karen because you dont like the advice given

[hassmaschine]

Blah blah blah. Way to derail a thread. This is exactly why that N54 meme is so hilarious - it's completely true.

[Smgs1992]

So agreeing that trading for a N55 powered 335i is a better option and way to spend the $3k that the OP is willing to spend trying to mod a N52 is bad advice? In what way? He wants a faster car and has the means to achieve it. If he wants more power down the road it is then easily accessible.
It is literally the smart advice. If he had asked what should i get if i want a bmw to get back and forth to work. I dont care about power. A 328i would be the correct answer.

If I could get a 335i I could but I can't

Do not explain yourself to these trolls. N52 is great reliable engine. Sure, it is not cheap to milk power out of it, but it is very enjoyable. e30 m3 had 193hp. e36 m3 had 230hp. e46 M3 had 333hp. N52 is capable of making about 300hp, which is not bad in any way. Being able to spin the engine to 7500rpm has its joy.

Edit: I edited my initial response as it was not worth engaging in further engagement with you. But, I can see you are Very original as well... LOL

Edit: I just realized something... You thought I was butthurt because someone suggested 335. And you thought it was about you? LOL... Narcissistic much?
Dude read the post and user name of the poster. Did it click yet? Let me explain it to you: Someone created an account Budget Efthreeoh a spin on Efthreeoh username (not original). Person posted the most cliche thing on this forum ever - buy 335 (not original). So, I called out their originality.

[tylerhart_21]

Ok with the suspension (M-Sport) how can you tell if you bottom it out. I think I may have but not sure. And what can I do to make sure it does not bottom out?

Thank you for the set ideas. I can see what we can do.
