Okay... how the hell did you get the nut on the flange of the turbo? Everything ive seen says to do it from the bottom. I cant get to it from the top or the bottom or anywhere. I can kind of see it from the bottom but thats it.

Im an xdrive auto car. And honestly i dont see how the hell its even possible.

There are no videos online anywhere that i can find. Im at a complete loss. I have the oan and rack cover off.

No, am I supposed to? I havent been able to find any videos or anything much less a good actual write up on what I need to do. Other than... get it from the bottom.

Are you following this guide? The water pump might only be necessary if you're doing the diverter valve at the same time.

Yes... I already have everything disconnected and everything, I just cannot find a way to get to the nut. I can only see it soft of from on angle and there isnt any way that I can see to get anything up to it.

I didnt see anything about the water pump in those directions... Not doing the diverter right now anyway.

Curious what your initial impressions are with the Pure Turbos Inlet? Getting mine installed in a few days.

Pure is great in general... in regards to instructions and etc or help... complete garbage. I emailed in and the reply I received was polite and the guy was great but he couldn't help at all and referred me to this site and to maybe ask Bryan Kiefer @ Kies... It was hilariously frustrating.

Post install observations... Its louder. There is a noticeable more intake noise (already running the injen intake). Its about a half inch increase in diameter so it is a rather big change so its not surprising there was a noise change.

Driving the car I dont really notice anything. However, I haven't been able to drive the way now in about 10 days due to time frame where i started pulling things apart in preparation for the install till yesterday.

Here is the logs...

This was the last log before the inlet
http://www.bootmod3.net/log?id=5d87c19fc090c658131412ee

Log from yesterday post inlet
http://www.bootmod3.net/log?id=5d9e32c1ae729b770a4213b2

You can see that I hit 41.4 on the Maf reading and it never climbs which Im guessing is because Im maxing it out, so I have no basis for comparison to see if it reads higher on flow or not. Not really seeing any real signs of change on the waste gate duty cycle. Since Im an EWG car, they are always high and BM3 says I do not have a leak based ont he numbers.

Did it hurt performance? Nope... but did it help? No idea tbh. I would say that its obvious why it would help with an aftermarket turbo set up and maybe on stock running really high boost.


Mods are..
Injet intake
Charge Pipe
VRSF 5" IC
Catless DP
BM3 E30 Map
BMW Trans Flash

Sorry it was a hassle for you. Ironically, Kies is doing my installation. I calculated, from pipe diameter measurements that were posted, that the Pure Turbos Inlet is 42% larger at that stock constriction point. I'm curious why that would translate into a noticeable sound volume difference. Perhaps your aftermarket intake is amplifying the sound so that you notice it.

I've got the M Performance intake which maybe sounds a little louder than stock because it has an extra air intake hole in the bottom of the air filter box. (That hole faces forward.) I use a drop-in aFe Pro Dry filter. Now I'm curious to see if I notice any sound difference.

Please post before and after logs if you can. I'm very curious to see if you have the same increase in MAF readings and how much they differ from 5000 RPMs on up. I haven't recorded a log but I may give it a try so that I have some "before" data before my installation.

You may not notice much of a sound difference with the stock air box.. too much built in sound baffling.

Logs are above.. as you can see, my results were useless.
