shhhh, don't spoil it with grown up stuff, I haven't told my missus about the upcoming mods yet

I've spoken to Turbo Dynamics today, very good conversation and they don't seem to be a bad alternative to RB turbos.

To be honest, I'd rather avoid running ethanol if possible. Could come around to the idea of a meth tank though.

I'd rather run the TD or RB turbos at lower boost, going for a comfortable 480 - 525BHP (so around 400ish rWHP). The idea is to retain reliability and not stress things *too* much.

Have checked removal and installation of the turbos and it's bang on at around £750 - £900.

Just have to decide where I source the turbos from, this should all be done by end of April though so watch this space... If only to see the flaming debris when it all goes tits up....

Interesting reading. The long term game for me is to go with upgrade turbos from RB. I'm not running meth either though at present but then I've only had the motor about 13-14weeks lol.

I've heard Darren Woods have fitted a few sets now to both E8* and E9* variants so definitely worth considering even with the long drive. Would be a good test drive home lol.

I think though that the meth route is a definite consideration firstly for me as I'd like to see where I get too with doing the other stuff before turbos. I'd look at the turbos as the finally piece in the puzzle after everything else (including brakes, etc).

Interested in the route you take and the outcome once done.

[surrey 335i]

Who have you found in the South / South east that will do the fitting at a reasonable cost? PM if you don't want to put it on here. Darren Woods have done a few and know whats involved hence the sensible pricing they quote its just a long way to go from London to get it done!

[AWSAWS]

Great to think it may be possible to upgrade the Turbos in the UK. There must be specialists about. Under £1000 would be good. I'd need performance clutches I bet.

By the way a 50/50 mix of meth and water in the boot is not flammable I'm told. It may be like Whiskey where you need a prolonged exposure to flames for it to ignite. Anyway you are driving around with a tank of petrol so what's the difference.

[russjonesr]

I have vargas stage 1's fitted by Darren Wood...they did it in the day which was good. I have fbo and run meth with a little E in the mix. Planning on getting a dyno done in the next month

[AWSAWS]

There are apparently also super RB turbos (stage 3).

On N54Tech - 'Update: Super RB Evolution into Stage 3 type Twin Turbos'

Hey Man, I've got the equivalent Vargas turbos on mine with FBO, all mods fitted at the same time by a company called ETA motorsports in Brands Hatch. My friend who's got a 1M rep (135i) with stage 1 turbos and FBO recommended them to me. They done a brilliant job and £700 in a day I thought that was awesome. They do it quite regularly and are BM specialists. Really do think highly of them, considering they quoted me 750-800 and charged me less.

I'm also not running meth because of the complexity and safety etc. Best to keep it clean and simple. Nice mods so far I think with a good remap it'll be enough. Mine without a remap at the mo is an absolute beast. I have an E93... few people from the forum have commented on how much better is compared to what it was previously... plus... I don't have an LSD and you do so that'll be good! ( I really want an LSD I'm jealous haha )

Just thought I'd let you know my opinion here mate. Good luck and wishing you the best :-)

Cool and nice upgrade. Any dyno runs done to give an indication of how effective they are without meth, etc?

[gangzoom]

Good to see so many people are now running upgraded turbos on these....I might have to re-think my 'no-more modding' status for the 335i

Not yet unfortunately. I'm getting the water pump and hpfp replaced this month, along with possibly purchasing some new tyres and shocks. So I'm aiming for next month for a dyno and remap hopefully by Evolve. We will see. As soon as I have the figures I'll get them up. My friends ran 410 at the wheels I believe and I was on par. So hopefully after a map it'll become evident :-) very excited!

[Lawton438]

Look forward to seeing the dyno's ,

I wanted to get them myself but I was told it was pointless basically without meth, as a standard turbo car with meth will run the same as upgraded twins without meth.

But it's not 'pointless' if you don't want go down the meth route...as clearly quite a few of us don't want to

[Cerbera9]

It would be good to see some UK N54's dyno print outs with the list of mods attached for comparison

[Lawton438]

Fair enough Its not pointless just an expensive upgrade for not massive gains and not maxismising the potential of the upgraded turbos

Hey mate, thanks, I'm hoping it'll all be nice and smooth!

I've actually had a couple bits of work done by ETA with mixed results. First lot was the engine mods, exhaust and brakes which went really well and a great price. Unfortunately they dropped the ball on my Ohlins suspension install, they rushed the job, cut corners (only minor stuff), didn't test anything and I ended up paying to take it elsewhere to get rectified. I won't slate their technical ability but the information and customer service wasn't what I needed at the time.

I don't think I'm far from you so give me a shout if you want to compare notes sometime, would love to see how those Vargas turbos are treating you.

[AlanYoro35i]

I've been thinking about this too ever since i got beaten by a SL63 amg 13 plate which has 560 bhp twin turbo V8. but i really fancy a new car lol

[nicktyler]

By going turbos 'instead' of meth you are getting similar power but you are also getting better reliability, not stressing the parts so much and not going to get caught short on meth which I imagine could happen. Not to mention the hassle and cost of keep refilling the meth.

Of course you pay your money and make your choice. Be good to have both!

LoL, as they say 'there's always something faster'

I think a mildly tuned 335i (360-380bhp) is already faster than 95% of cars on the road, one running uprated turbos will be 99% quicker....

I know what you mean about wanting a newer car, but I took mine out for a B road blast yesterday....and I couldn't stop smiling at the end of it. Interms of pure driving fun I cannot fault, the handling, noise, engine response of my tuned 335i

Forget a new car...I'm keeping mine. Going to keep an eye out on how OP manages with RB turbos. I'm going over to the states at some point in the next 12 months....might come back with a suit case full of turbos

Totally agree.

I still have a 56 plate E92 335i I've had for years and when it came to replace the other half's Cooper S (a moderately tuned R56 Lohan, TONS of fun) last summer.. We tried a LOT of different cars, she didn't like most of them, the only one we settled on was the E93.

Just upgraded the CIC to NBT (build thread to come once DAB is finished) and it's like a new car, spectacular upgrade. Added to that, with the turbo upgrade, it'll make it a reasonably practical hardtop convertible daily driver with 500bhp+ on tap. I can't think of many other cars around that tick all my boxes, even for the cost of the car + the amount I've spent on mods.

[AlanYoro35i]

Personal preference really, i don't like outdated things but i love my car, had it 4 years and every time it keeps me smilling, but then there is no other car that has so much tuning protential(400+) 25mpg+ cars around that don't cost all of my limbs.

I really want to put new navigation on but i know if i touch it further i'll be keeping this car until it dies lol.

if only the misses knows how to drive then we can have 2 cars. keep my 335i and turn it into a monster and have a 428i vert, that i think would be the best of both world for me.

I've only had mine 18 months, but I don't know what I'd replace it with. I look at other cars on the road, and none of them really do it for me. In NZ we have a lot of V8 Holdens and Fords which are pushing a lot of power from the factory thesedays - but I still don't care much for them. Too big, too obvious and too garish. Plus they still drive like a taxi with a big engine. I like the new Audis - they look great, and are probably fantastic to drive - but I can't afford one anyway so it's irrelevant. Same goes for the new M3. The New F30 - nice, but not different enough to draw me from my E90. I've done the Evo thing, and point to point they're great. But they're still a cheap car made to go fast and at 35 I'd feel a bit silly in one. For me, the E90 M Sport 335i is spot on. It's a lovely place to sit on a journey, big enough to be practical but not too big, and looks purposeful enough in M Sport guise but without the need for spoilers or tacky add-ons. Plus of course the engine! I know it's not 'special' in the true sense, but I don't care. It feels special to me, and with uprated suspension and a remap it's still near the top of the pack in terms of performance.

Honestly couldn't agree more with what you said! My Mrs was exactly the same! (Obviously we don't tell her how much the mods cost... well I don't otherwise shed most likely kill me)

Nevertheless such a great box ticker
