They're not specifically for 128i/n52, see how it says universal and has vtec listed lol

I guess, thought I had a great find since it was listed when I searched for 128i. How the heck do they work as "universal" anyway, makes no sense to me, I would think they are always specially made for each engine, no?

They probably do not work. They just universally deplete your wallet!!

It's just typical HPF bullshit. They love the quick buck/con.

Exactly. If you pick one it lists cams and what engine each one is for

Btw i found a guy who's apparently done full head work with cams and throttles bodies and stuff - see if he replied

Ooh that's nice!! Where does it list the price? :/

Better exhaust, headers, proper tune.. Would be delicious.

I wonder why this stroker kit isnt available for 128's?

It is, same engine, works on ALL n52b30's.. 330i, 128i, 130i etc.

Just wondering because the 128 isnt listed on vehicles the kit is available for.

Maybe because Noelle is a Euro tuner and the 128i is not available there? I think someone emailed them once and confirmed that it would work, though. In any case, from what I remember the kit is absurdly expensive.

That makes sense.
Stroker kits are very expensive not to mention installation!
Thought about a stroker for my Corvette but went the Super Charger route instead. If I blow the engine a 403 ci stroker will be put in and keep the blower on.
If I had a 128 I would consider this kit, depending on how much, of course.

From google it's apparently about 5k euro for conrods pistons and crank.. When mmw brings out their blower it will apparently start around 6k USD.. Take a bit off since using their tune would be stupid.. Add on a proper ECU, i'd guess around $15k installed and tuned

Not cheap lol

I figure if i keep my car long enough, i'll probably end up doing a ton of stiff to it, which would satisfy my want for a more powerful car too lol

Given the trouble I had finding even a semi-competent shop to do a simple coil-over install this past spring, the biggest obstacle might be finding one I trusted to do something as labor intensive as a stroker kit on my N52. But it's one for the wish list, to be sure. It would be pretty epic to be running probably the only 3.2L 300+ WHP 128i in North America.

it's always a good thought/feeling having the 'only'/most of anything, even if it's not the fastest, there's big points for being unique.

in about 6 months i'll have probably the only wide body E87 in australia, and with the tire sizes i want to run, i'll have at least close to the most rubber on the ground

thx

Exhaust is composed of catless downpipes (based on 130i Supersprint, expensive, but the best) + straight pipes (probably forbidden in most countries) that totally open the engine character. Even with some 12-16 HP of added power by exhaust the engine feels different, breathes freely and adds a lot in lower RPMs.
ECU programming is custom made and it is just final touch, after exhaust is replaced.
Noelle offers cams and classic NA tuning, bit expensive (eventually possible to negotiate 5000 $ price point).

Where on their site do they list cams for n52?

I think its in the PDF

Or maybe on the UK website that promotes this kit as a Hartge design



Also personally, I think i'd be happy to stop at ~290 hp
Not because I don't like power, its because I cant use it in daily driving, and I don't track my car

Thank you very much guys!!

I've just discovered that I can transform my E82 125i into a 130i only with sofwtare modifications.

But, I have a big problem now... I need to find a spanish chip-tuner to do this... and I think it will be impossible

Most tuners take ECU by mail and return it to you.
http://www.ms-chiptuning.de/
wintertuning and others exist.

shop around and just knwo that one for the german ones is a offshoot of a more reputable company ( could be wintertuning)

Also let us know which on you used, as we have very few english reviews of Euro tuners

[sumbeam]

Thank yoy Andrey. I'm speaking with 4 chiptuners here in Spain and they are studying the case. But they said there won't be any problem I'm sending to them the original ECU soft of a 125i and 130i so that they can analyze them... but I think the only thing to do is to activate the DISA function that is "disabled" in the 125i... and copy-paste the 130i into my 125i ECU..

Your welcome!

Can I get more info on this? Where did you get the files?

Also, not sure if i mentioned it before, but 125i needs a change somewhere in the air intake pipe, that is how euro tuners unlock the 125i in addition to DISA
