Just about set on a 335i

46 posts in this topic

The time has come I think to buy some horsepower. My trusty E46 has served me well and I do love the chassis but I am hankering for a bit more grunt. My budget is $20k ish and looking around there are a few E90/91/92's in that range. I drove a NZ new coupe and I did like it but I saw a nice Motorsport Touring in white and I have to honest and say it looked lovely. The Coupe front end is much nicer in my opinion but I am thinking perhaps I should get something a bit more pratical.To be honest even the Sedan in Motorsport trim looks good especially when the chrome kidney grills are replaced with black ones. The real reason I want one of course is the engine. I am interested to hear anyone's N54 tuning stories; it seems to me that MHD is probably the way to go especially when supported with a few  bolt on parts. Also curious to know more about a walnut intake port clean, oil catch can upgrade and general service issues. Oh any if anyone has done a Koni/Bilstein or other upgrade what did they find? I am partial to good suspension after having Ohlins on my E46. What bushes wear out and are poly bushes worthwhile? So many questions...

I'm in denial about the 335i John, I think you're absolutely on the money.  I'm heading for a 330i myself.  I'll be hanging on to the e46.  Shame I can't justify three vehicles, I'd snap up your coupe in a heartbeat.  Denial?  Yes, I love the idea of the grunt and fun of the 335i, but my wallet says "be cautious young man, the next one's for two years only", and I arrive back at the 330i.  That's more to do with my personal income risk, and is not a reason for others to avoid the 335i!

I think the motorsport will be the way to go; non-msport you'll miss out on the seats and have to do all your suspension.  The downside of Msport in the e90 series is that damned black headlining and pillar trim, does make it seem a bit grim inside.  The windscreen seems smaller (pretty sure it is smaller) than the e46, so coupled with all that black it's a bit like peering out through the slot in a pillbox.

There's some photos on a recent thread of the walnut intake clean, looks like a very good idea.

One of those boost pipes (I forget which) is plastic and breaks - particularly with added tuning (boost), so normally replaced with an alloy item.  

They're a bit more complex under the hood than your NA unit, so you can expect a little more $$ in maintenance... but look at what you get in that package, eh?

Do it.

Oh, hang on, let's try that again:

Best "suspension upgrade" is replacing the runflats with regular tyres. MSport is a great option to have, note it can come with an oil cooler too which probably helps if you like to thrash it (the main reason you'd get a 335i really).

Charge pipes explode soon after an engine tune, so replace that before you do anything. Mine lasted only a few weeks weeks after a Performance Power Kit flash.

Have it inspected for turbo oil leaks and wastegate rattle, otherwise spare about $4k for a turbo replacement.

335 is a very tempting vehicle  and on my shortlist - only wagon and sedan as coupe does not have 5 seats.

equally tempting is the 335d   and M3 both on my short list

John, I bought a 335i touring M sport in Feb after having owned Audi's for most of my driving history. Fantastic car for the price range in terms of performance and interior fitout. Mine has had a number of performance upgrades to it like down pipes, pod filter upgrade, gearbox tune, cobb accessport tune the list goes on. Intercooler and catch can hasn't been done. And the reason I always buy wagons is for the space for loading all my kids stuff!

It's very fast. The previous owner thought it might be 420hp at the crank but it was never put on the dyno to verify. Basically it was built to the same spec of one that ran 420hp. It had had the walnut blast done before I purchased it so I can't tell you much about that. If you would like to come and have a look at it, you're more than welcome. I could take you out for a run and you can see the performance for yourself. I'm in Newlands.

Faizal. thank you for the offer I would very much like to look at your 335i, it's a very sharp looking vehicle. I will make contact soon.

Ron I have also gone over a similar short list but keep coming back to the 335i mainly because it's such a value proposition. Pretty hard to find in manual though.

Sam the 330ci will be on here soon, I will be a bit sad to see it go as I have a lot of time (and money) invested in it. 

Matthew I agree with you on the run flat's, I had them on my E60 and they were harsh. Charge pipe seems like a must do even on non tuned cars. 

Olaf, we can always swap cars again for a drive :D

This has piqued my interest: http://www.trademe.co.nz/Browse/Listing.aspx?id=1133470442

As has these :http://www.trademe.co.nz/Browse/Listing.aspx?id=1135390950  http://www.trademe.co.nz/Browse/Listing.aspx?id=1134022572 

and of course a Coupe: http://www.tradeinclearance.co.nz/search-stock?sn=8456

I have driven the Coupe and it's nice NZ service history from JG and the wastegates have been done under warranty, I would have preferred less Km's though.

This is what I worry about though.

isn't the M3 coupe only as well (and hence not 5 seats)

I got some WG rattle in the rear turbo which is quite common. Its easy to fix though jack up remove wheel and reach in with small spanners to tighten the rod. Apply vacuum to WG so you dont under/over tighten it. 1 hour max from start to finish.

Yeah but if you look at the video the wastegate problem is more to do with slop in the bushing so tightening it won't completely solve the problem.

Value proposition is the strength of the 335

Andy - both the E36 and E90 are M3 Sedans , if we were pedantic they  and the current M3 are the only true M3's  by BMW's historical nomenclature - hence the "new" M4  designation

So the waste gate rattle is really a poked bearing and adjusting just disguises the problem - the real fix is replace the bearing and probably the shaft.

5 minutes of silly video for a 5 second  diagnosis.

Great idea John, I think we should do that quickly, before you've let the Ci go.  I think you'll be impressed with the changes to the touring, and I'd love to see how much further your Ci has come since we went to Samson.

Spend 2-3 days pulling turbos apart to replace the actuator rod mechanism. Or spend a few minutes to tighten a rod to get rid of the dreaded rattle and fix 95% boost leak.

If that works for you then fine, but it's not a solution to the problem especially if you want to grab the extra HP that is on offer with a tune and a few bolt ons.

Well at least you are now fully aware Ron.

There are rebuild kits for  a few hundy  so if you put the hours in  yourself it is a reasonable fix.

The problem definitely appears to be the bearing, BTW the turbo is a Mitsubishi part , so whilst it is fitted to a BMW the "quality problem" originates from Mitsi.

50 50 on that one Ron, The problem seems to be where BMW have placed the turbo, and so close to the output of the ports apparently causing a harmonic issue and vibrating the shaft enough to put pressure on the bearing and cause the chew out.

Fair comment Josh, there are bound to be contributing factors  that we are un aware of.

Harmonics are usually caused by uneven tract lengths and that is a feature of later BMW exhaust design in an effort to get catalytic convertors close to the source.  There will be points where the short  centre pipe is a multiple of the longer outer pipes and this will create a strong pressure harmonic.

The high boost and even higher again of modified 335's will definitely generate strong pressure harmonics.

If you really like the e46 why don't you look at upgrading the power on the m54b30? Supercharger or turbo would give you plenty.

Alternatively an e46 m3 is inside your budget.

he's already considered both of those options, I think the 335i is one of those great 'bang for buck' options that's hard to beat.

Yep 335i can make 400HP with a small investment and the chassis is decent.
