Pure Turbos - turbo upgrade??

http://www.pureturbos.com/store/

Does anyone know about these guys? There in Oceanside. They contacted me through pm inquiring about me participating in a turbo upgrade effort, to be a test car. I'm sure they also sent many pm's to others.

Not sure I would be willing to do that considering there has been some blown motors already. Stock turbos are running at 17psi already.

I am hesitant. I feel the n20 hasn't been modded by enough people and also it is still a new motor that nobody knows the limits of.

I was just curious if anyone else was contacted and why they didn't make a post about recruiting people.

I've read your posts and it seems you have successfully gone pretty far with the N20, I say go for it!

I just want to throw my 2 cents out there to you and others, keep in mind that turbo changes aren't always for huge horsepower and torque - they can also move the curve with great results rather than simply adding to it.

Take a look at their N55 stage 1 here. Check out the dyno chart, and reference the N20 JB4 dynos to see what I'm talking about. The N20 is engineered for good balance of efficiency and performance, and the turbo plays a key role. Changing it to something that flows better at high revs can move the torque and power peaks higher and/or flatten their curves, where the factory N20 will taper down (because it's optimized to lower revs which is a tradeoff of peak performance). Without getting too deep in the HP vs. TQ discussion, I'd just point out that moving the torque higher up in the revs results in greater power even at the same amount of torque and boost as JB4, for example, if you can follow that explanation.

That being said, Pure should probably consider taking on some of the liability that they are asking for from a development car, with the rod incidents we've seen from turning up boost.

the way i see it is if you're into performance then go for it.
as long as they are willing to compensate for any damages they may cause to your engine ei. if your engine blows up they have to be willing to replace it. Depending on how reputable they are I would also tell them that i want a dealership to replace the engine if that happens.

I understand the whole power-band spectrum and that an upgraded turbo doesn't necessarily mean destruction.

I have a guy that will do the dyno work for almost nothing and the upfront cost is under 1k. This cost covers the new turbo/mani only and I have to send mine back which I don't like. I would rather wait to send it when/if I determine the upgrade is successful. I have to then get it installed (easy enough). They basically want a before and after from the dyno and plenty of data logs to tweak the JB4. They claim to be working with Terry and I have yet to confirm this. Having Pure Turbo back my motor is going to have to be a must!

It seems that nobody knows who Pure Turbo is. I will be contacting Terry to see what his involvement is.

Maybe the N55 people know more. I only noticed that their dyno charts indicate JB4 tuning.

Did you find out any more on this? I personally like this idea going forward. Apparently they actually have a stage 2 turbo upgrade completed too.

I wonder what precautions we would have to take. Perhaps higher strength rods?

There are few people out there that did turbo upgrade not pure turbos, I can recall someone at 2 series that has 228i

Would def take the cautious approach on this, personally I'd probably avoid it all together.

I have decided against it until or if there will be internals available for the n20. I would have wanted to push the motor at that point to get the most of a turbo upgrade. The cost would have been about $1200 out of pocket for me, vs the claimed retail of 2k.

Pure turbos have been releasing quality products for BMW N55 and S55.
I can easily assume that they will do the same for the N20 and N26.
We saw them at shift sector a month ago and their M4 performed really well.
They also broke the dyno world record for the N55.
If anyone is interested in turbo upgrades they should seriously consider this option.

Research I had done in the beginning showed them to be pretty active in the n55/s55 market.

I will consider the upgrade when it is released. It's worth it to me to pay the extra $800 and not have to worry about being the test subject. I was a test dummy over a decade ago for a turbo kit on a Mitsu and I was able to walk away with a free kit. The incentives just aren't there with Pure.

I contacted them to find out what the deal was with the N20 upgrades. Here is what they had to say.

Pure: We already have a N20 Stage 2 turbo. It's been on the back burner because the N20 community seems to be so afraid of engine damage. There doesn't seem to be much of a market for it.


Stu: That's interesting. I've only read about a couple engine failures. Funny that there are plenty of 2 liter engines making far more than 300bhp, so I guess it's just time until everyone works out what to avoid that would lead to an incident.

Stu: Can you let me know what stage 1 and stage 2 would offer me (I assume higher possible boost and flow, plus maintaining higher flow up though the higher rpm range).

Pure: I agree, I think there is a misconception on the strength of the N20 motor. On this platform, a Stage 1 is not worth much. The stage 2 turbo will make a huge difference. It will provide increased efficiency and any boost level you want to run. We won't be surprised if it hits the 350 to 400whp level. And yes, it will allow the top end rpm range to hold power.

Stage 1 is a compressor wheel only upgrade

Stage 2 is a compressor wheel and turbine wheel upgrade

I have received the same comments. I can't say I trust the internals with that much power. The n20 is already a high boosted and compression motor from factory.

I agree with you. I don't think I will be the Guinea pig on this one. Not unless, like you, there is backup from Pure.

Hope pure turbo can do a test on n20 to show people that stage 2 is durable! I can't wait to push more power out of my n20.

These guys are about 20 mins south of where I live. Maybe I'll stop by and check them out. If I'm feeling extra adventurous I may offer up my car as a test vehicle.
