The big day is here...N54 Single Turbo

AltecBX · 05-06-2010, 08:05 AM

Jpsimon did an upgrade turbos and that car is a beast. His logs are very strong and just as responsive as smaller turbos.

It is only about 50 rwhp on that setup at most and the cost including installation is about $4500. That is very pricey for that little gain and there is no wastegate fix so it is just as likely to rattle as the stock. I think that is a tough sell there. A full turbo upgrade is the way to go if someone brings a kit to market.

Progress has been made.

Turbo Dynamics stage 2 upgrade has a delta of around 100 hp and also offers a wastegate upgrade. It's more expensive, though.

I'm not too much in favor of a single turbo as my objective is to retain as much as possible the responsiveness and lack of lag (!) of the N54 biturbo concept. I can't really see that with a big single - even if it makes more power. But that's just my subjective point of view.

And BTW... good luck with this endeavour!

WCM3 · 05-06-2010, 11:04 AM

ahh..my old 335i is in for a treat. Hope you're enjoying it, Justin.

And definitely post pictures of the build. At least the hardware fabricated..always love that stuff.

AltecBX · 05-06-2010, 09:20 PM

I'll give you a hand. This is very nice progress..

kennejp · 05-06-2010, 09:50 PM

looking good man-keep the updates coming! quick question-i dont really understand the reason for the 2 wastegates? Any pictures of the manifold yet? Also when you say 2 bovs do you mean one dv to recirculate and one bov? I dont understand this either.....

Tiago@VRSF · 05-06-2010, 10:01 PM

Twin wastegates are there because they are using a divided manifold for the twin scroll turbo. 1 wastegate for 3 cylinders.

Was kinda hoping to see pics of an actual turbo kit

I hope they aren't planning on using that intake...

kennejp · 05-06-2010, 10:04 PM

Oh gotcha. I didnt/dont know about twin scroll turbos. Any idea about the bovs?

unfor · 05-06-2010, 10:06 PM

No. That intake was removed. along with that charge pipe.

mkato13 · 05-06-2010, 10:23 PM

This is got potential. Just hope it gets finished

IS got, or has got?

Another day, and some more progress regarding the mounting of the turbo and the flange of the exhaust manifold. Now comes the challenging part, fabricating a custom exhaust manifold. Luckily, the design has been finalized. This is really the most challenging part, as the stock design was a bit tricky

atlxkevinx · 05-07-2010, 08:05 AM

progress!

This guy is 100% legit, can't wait to see the final product.

Thanks everyone for the words of encouragement.

Cool! I'm glad someone is throwing down the cash to get this done rather than making it sound like it was some Hurculean engineering feat on the scale of attaining a sustained, controlled, energy positive fusion reaction.

unfor · 05-08-2010, 03:21 PM

Thanks. I will have some pictures up for your enjoyment today.
