Turbo!!!! N52

ale90 · 05-05-2015, 09:06 PM

I know I know " Don't do it" well im to curious and Im trying it. First im going as simple as I can using stock manifolds and fabricating a y pipe to the turbo. Relocate the coolant resevoir and mount the turbo behind the passenger light. Of course cuatom downpipe and exhaust. Front mount and intercooler thats easy. Oil feed and return lines ... Don't know yet. Tuning is my biggest concern. Anyone have any ideas?

For all the work that a turbo setup will entail (I have turboed many cars over the years), the issue right now is fuel. Turbo or not, you will be limited to the limits of the OEM injectors, which max out just around 300whp. That is at least a reality for now for the SC setup as well, until/unless we find a suitable larger injector (they are very specific injectors). Without a better fuel option, I wouldnt think it would be worth while to pursue a turbo setup being limited to 300whp. Tuning will be another issue.

Understood. What is so special about the injectors?

This turbo a N52 is a crazy notion, look how much testing ESS, who is a reputable dealer, had to go through to make sure their SC would work. I would just buy a SC. The turbo is not a good idea, who is going to tune it? Not to mention the injectors are specially made for the vanos...which limit you to around 300whp

My shop in NC is starting a turbo N52 project.

I can PM you their info.

Benan · 05-06-2015, 02:14 AM

I would save my self the truble and just find a nice 335i and get some bolt-on and enjoy the 400hp if more power is what you´re after..

SPJR · 05-06-2015, 02:36 AM

I clicked on this thinking wow someone was designing a turbo in the dark this whole time and got it working!

I'm leaving disappointed

I dont think I can find a 335i as cheap as I bought this 330i. And the money to be invested is not going to be bad. I work for a speed shop most of it is going to be time and figuring stuff

Dan Bilzerian · 05-06-2015, 07:38 AM

I've found a couple 335's for under 16 and they're manual.

It cost me 1k... It wasn't running and it had a rebuilt tittle. A spring from the variocam came loose. Had a spare n52 in the shop. Fix the car with no out of pocket money. Like I said very cheap

Can't you just l use n55 n54 manifolds and turbos? They look like they bolt up with minimal issues

Good luck

Thats a good question ill have to verify. But controlling the wastegates on the stock 335 turbos is a challenge. They dont work as your usual wastegate

The blocks of the N52 and N54/55 are different metal composites and as such, tolerate more heat or pressure vs. N52.

Fitment is not the issue. The actual metal of the engine block is, IMHO.

You heard of Bimmer Performance Center in Raleigh?

They posted it the other day on the NC BMW enthusiast Facebook page. It got heated haha, although now that I look for it I can't find it...

I think the metal would be fine if you don't overheat it or boost too much.

the bigger issue is BMW already made a turbo N52. it's called the N55...

Right, but the two are made from different types/ratios of metals.

Which renders the following:

Even if you could 'pull' it off, how could you justify running such low boost with such little results for such a high investment?

Not trying to shit on a parade, but per my research the main issue with the two engines.

Very very different engines - N52 is actually the more advanced design, lighter with magnesium and aluminum constuction, N54 is also a 2 piece design, but an all aluminum engine, so block, heads, intake, pretty much everything is different except some of the accessories that bolt onto it, like the electric water pump, alternator etc. N54 is also direct injection, so has 2 fuel pumps instead of just a low pressure one.

Anyways, just wanted to offer that technical insight that could be over looked.

hassmaschine · 05-06-2015, 10:59 AM

I realize they aren't exactly the same - but the N55 is as close to a turbo N52 as you can get (similar heads, valvetronic, etc).

Go for it. There are plenty of people out that are capable of tuning it. Hardware is the easy part
