Don’t know if its significant but in most of these threads it looks like the most enthusiastic “buy M3” guys are driving older 328/335’s. I also think that a lot of the fully optioned 335is buyer could have bought an M3 instead but like me don’t believe it’s a useful street car.

Also like me I bet a lot of new 335is buyers will be moving to the F series M3 turbo when it comes out with bottom end torque.



Its also interesting how the little Burger Motorsports decal attracts M3 like a moth to a flame. Other then the decal it’s a pretty good sleeper.

Better suspension? where's the stock LSD?, better tranny? It doesn't seem to be able to hold more power than the 6AT without a rebuild. The DCT also has cooling issues, as I'm almost 100% sure it lacks a DCT cooler, like the M3 and goes into limp mode when pushed. more power? take a look at the dynos, it's just a tad bit more low end torque. Without the abusive launch control, you're in the mid 13's.

Enough talk though. I just got back from gingerman raceway yesterday, where I had no trouble keeping up with a modded E90 M3, who is a friend of mine. I'll be there again in may, and will be in Mid america motorplex in July. If you, or any other 335is in the chicago area, want to show me this big difference in person at the race, please PM me.

Thanks.

Changes since then New 335IS specific custom Map 6 no charge, FMIC $750 delivered current power has increased but how much is unknown.

So, would JB4 be OK for a lease car, and be able to return it to stock later?
For a stock 335is, would Map 2 be fine on pump gas? Map 5 if I mix in 100 octane?
Lastly, do you do any track days or just drag racing? I am signed up for Kershaw in May. But will likely do stock as a base-line, although Kershaw can make use of more power.

Some answers.

I don't use launch control & car will run in the 12's with a 2nd gear start as recommended by Terry at Burger Motor Sports. Map 2 & 6 is good on 93 pump, Map1 & 5 for 91. My pure stock baseline dyno was 314whp. 335i generally run 277/280whp & as low as 265whp on 91 octane. The stock IS as opposed to "a little more torque" has about 80ftlbs more then the 335i.

One of the other 335IS guys with a German developed tune he is testing for them & who has an FMIC & does use launch control is running 12.0 with 1.8 60 foot times also with no transmission problems. Expect if he adds down pipes it will drop nicely into the 11's with no heat or trans problems.

Drag race on occasion at Rockingham, NC but have not done any track days in it yet. I will go to VIR when the NC BMW club goes up there. Not serious about either just looking for a little extra on the street.

Way back when had a number of sponsored rides & hold both NHRA & SCCA licenses

On I6 & V8 M3's I can/have just driven away from them both from a standing start & a roll. Compared to the V8 I have about 10 more BHP & 105ftlbs more torque which comes in about 2100RPM sooner. The V8 M3 should be better at a track day due to suspension. Not bad for $500.

I have not run the new JB4 IS specific Maps against the clocks yet. Someone else with the same car less the FMIC I just added (my only mod outside of the JB4) + a DCI has posted IIRC 12.5 @ 114mph from 12.8 @ 110 with the new Map6. Not sure what tires he was running but I have Conti DW 265/30/19’s on the back & 235’s on the front.

BTW this is a pure stock 335IS first drag strip run, best et 13.1 with run flats. Watching this guy trying to stage you can tell he is not a track rat.

The JB4 can be unplugged when you want to turn in the car also a good plane for warranty claims. Will take about 15/20 minutes mostly to remove/install the underhood plastic panels.

Some EDITS

A JB4 135I N55 7DCT made some 12.0 - 12.2 runs today

Hmm just drove a 335is and it pulled hard, I've had a jb4 on my car before but it feels like the 335i always needs to downshift first and spool where as the 335is was ready to do. No spooling. No turbo lag. Just 370ft/lb of torque ready to blow in your face at the push of the pedal. Didn't need to floor it, just put it in sport 2nd gear at 30mph, 40% paddle depressed and damn.

Which year 335i are you comparing to? The 335iS has the same engine as the 07-10 335i (parallel twin turbo setup (n54) engine). It wasn't until 2011+ that BMW started using the n55 (single twin scroll turbo setup) for the 335i. Although both the n54 & n55 have about the same small amount of 'turbo lag' the n54 335iS has an additional radiator and beefier engine mounts. The n55 may actually have just slightly a bit more lag but nothing a human could probably notice. So, in terms of 'turbo lag' there's no difference between the 07-10 335i and the 11+ 335iS because they run the same turbo setup. If your 335i is an n55 then it's probably the difference in WHP because on average the 11+ 335i n55 produces at peak dyno 266hp and 302 ftlb trq while the 11+ 335iS produces at peak dyno 293hp and 343 ftlb trq.. If your 335i is an n54 it at stock produces anywhere from 276-287hp and anywhere from 287-296 ftlb trq so not much difference to feel.. I'm assuming your 335i is an n55.. And where are you getting that the 335iS has 370 ftlb trq??

Edit:
Also suspension is the SAME..

[Eddien123]

M3 is expensive after the purchase. But it is a much better car and engine. But 335is if you decide against the M

Lol he's right though there isn't a huge diff. Only added radiator, beefier motor mounts and at most on dyno stock to stock 07-10 335i to 11' 335iS maybe 10hp.. In my opinion The diff is comparing an 11+ 335i n55 to an 11' n54 335iS.. About 20hp diff stock to stock..

You are wrong sadly.. The suspension is the same the tranny is the same.. Cooling is slighty diff.. N54 i to n54 iS is almost no diff in hp (10hp if that..) n55 i to n54 iS I agree with you in part but only hp wise.. Suspension. And tranny are still identical..

[RSL]

Stock 335is runs higher boost levels (overboost) than N54 335i, giving 370ft-lbs, and is the entire reason for the extra motor-related hardware. DCT is a major bonus.

I have an 07 335i, N54, no codes or leaks, turbos were replaced 500 miles ago. When I floor my 335i the full power kicks in at ~3300RPM until then, in those split seconds, you can feel it build up to 3300RPM. Then you have full power. When I shift downshift myself and then go WOT, it's the same. Also 40% depressed peddle on the IS delivered hard, where as my car doesn't deliver full power at 40% (the appropriate gear was selected on both cars). It's weird and doesn't make sense, it shouldn't be like this. But this was one thing I felt when test driving the S4, it also had an easier time delivering full power, same as the IS. The 335IS has overboost for 7 seconds(?) where it does put out 370tq.

I'm thinking this is because of the software based ecu updates that were applied to our cars to reduce/stop turbo rattle. Quite a few people say the car hasn't behaved the same since, even with the wastegate retrofit option on the software. The IS did seem to have turbo rattle, although I wasn't able to verify it, I just heard rattling and assumed turbos.

The 335is just smacked the entire torque in my face right from the initial depression of the paddle. There wasn't a build up to max torque, it was all right there. Plus it felt much smoother and linear. I've driven other 335i cars, N54 and N55, they felt the same as my car.


And the DCT was awesome.

The 6MT 335is also gets a stronger clutch, getting ready to install one into my 07.

In my opinion, the 335is has a high cost premium for what you get.

out of curiosity, why does the M3 cost more in the long run compared to a 335? m3 doesn't have twin turbos, plagued injectors, water pumps, HPFP issues. i can go on and on.
oh yeah and...
LIMP MODE lol

[RSL]

Overboost is supposed to be low-mid rpm band, from full boost up to about 4500-5000 rpm. It's supposedly disengaged before peak HP which is why that figured is not rated significantly higher as well on the IS. I don't think I have any logs saved with stock overboost anymore, but mine ran about 12-13psi and then tapered a bit up top.

[KevinJ]

They dyno tested early and late 335i N54 and N55 and 335is. In all cases, 335is clearly making more power and torque.

http://www.automobilemag.com/reviews.../photo_16.html

http://www.automobilemag.com/reviews.../photo_20.html

They don't use the standard PPK software in the 335is, it is custom mapped for the 335is.

Another bit, all turbo models including on the Mini uses an over-boost function. The 335is has a higher boost and longer sustained.

+1. The big difference is the option of the DCT. And as far as suspension goes all E92's have the same sport suspension. 328,335,335is all the same

[KevinJ]

1. The 335is comes standard with a different version of the M body kit.
2. It includes a sculpted rear valance (diffuser) matching the body color versus the standard M kit which is black ABS only. BMW said the diffuser was functional (not sure how much though personally).
3. The 335is includes these standard M package parts: sports suspension and other M bits such as thicker steering wheel, chrome accent peddle and foot rest, M door sill badging.
4. Black chrome exhaust tips, black grill and black shadow trim, and anthracite headliner
5. Black mirror caps also which are not part of the M kit.
6. The exhaust is a modified sports exhaust and not the standard BMW PPK sports exhaust. According to BMW, they removed some of the fill to change the sound and also added a valve like a standard exhaust to control the noise where the normal BMW sport exhaust doesn't have this. The 335is exhaust differs from the 335i, 335i with M kit, and BMW branded aftermarket sports exhaust and unique to the 335is.
7. Also according to BMW the motor mounts are stiffer than a standard 335 and not available on the standard M kit.
8. There is the availability of the DCT transmission which you can not obtain on the standard 335i or 335i with M kit unless outside of the U.S which varies by country if available on the 335i.
9. The 335is uses the older N54 Turbo motor
10. The 335is includes tuned sports software not standard on the 335i and not the same software as the PPK M kit.
11. The 335is gets 320 hp and 332 lb-ft torque from the twin-turbo 3.0-liter inline-six engine, and an overboost function allows for seven-second blasts of 370 lb-ft of torque.
12. The 335is has additional radiator, oil and a larger cooling fan compared to the standard 335i or 335i with PPK M kit. "An additional radiator has been added behind the left-side front air intake, along with a more powerful electric cooling fan. An oil cooler is fitted opposite the second radiator, on the right side." Source BMW.
13. Foglight delete for better air cooling to support the additional radiator and oil cooler and not an option on the 335i or 335i with M. 335is convertible retains foglights. This gives a different look to the front compared to M kit.
14. The 335is includes a 335is cluster gauge with color/badging and different from the 335i, not just badging.
15. There is unique 335is badging on the outside and inside.
16. 335is includes Glacier Aluminum Trim standard.
17. The 335is comes standard with 18" 313 wheels standard with 19+ optional. The 335i M package no longer offers the 313 wheels standard.
18. The 335is comes standard with paddle shifters.
19. The 335is offered a sunroof delete option. This option may have been available outside of the U.S. or on request for other 3 series models.
