ive been looking around on boost set ups people have done and i see a lot of peopple doing non vanos turbo...i would think boosting a vanos m50 would be better..am i wrong? im just curious..is it harder to tune or something, im still researching it but i was just wondering if anyone knew...

nevermind i found out why...but if done right and tuned right wouldnt the vanos turbo be better? -

"The idea behind VANOS is to produce the flattest torque curve possible from a given engine capacity without sacrificing top end power. This is why VANOS engines produce such great torque from a small (relatively speaking) capacity. In theory, if boost pressure was consistent across the entire rev range over which VANOS operated what you would see by turbocharging a VANOS engine is the same torque and power curves on a much larger scale. Whilst modern turbos with variable vanes etc can improve low gas speed response on a biggish turbo, they still cannot work miracles and produce constant response and boost pressure over the entire rev range. To an extent you would still have to decide on where in the rev range you want the turbo to have the greatest effect. If you got the combination of turbo, cams and VANOS set up right though (with a really good ECU to tie it all together) you would end up with an engine with far less power and torque curve compromises having to be made and an engine with a much more useable spread of both power and torque."
pulled this from something i saved a while back, looked into this aswell. just go m52 turbo. supposed to be the strongestComment

How does the vanos respond to supercharging?Drive it hard. Maintain it well.

still boost man.Originally posted by mr2peak View Post
it CAN be done turbo/supercharger. and yes, if you have the time/money to tune everything to work with the vanos and visa versa, then you would have a great set up.
here, pick 2- fast/cheap/reliable.Comment

fuck it ill go 2jz lol itl be easier for what im aiming forComment

Go with the vanos engine, more power potential with a few tuning options. Non vanos you will need a stand alone.
Great choice would be an M52 with MLS, ARP's, DME tune for 400rwhp all day long on pump gas and reliable.Need a Turbo manifold? We have them in stock- Click here---> http://rapidspoolindustries.com/

The only reason people go for non vanos is because it is the easiest and cheapest option. If tuned right the vanos should make more power. M52 is the way to go if you haven't already bought the engine. That's the one thing I wish I had done differently.

Im boosting an M50 vanos....tons of off the shelf tuning options (TRM, WAR, etc)...tons of info and support out there. 300whp should be very easy to obtain...that should be enough in my 2300lb e30 :)
I also wish I used an M52 right now too though.Comment

how deep are you into the build? The bore of the m50 and m52 are the same I think. you can take the crank out of the m52 and have a 2.8 m50...Originally posted by Chrisv006 View Post
the only reason I haven't done that is because I already paid a bunch to have my crank built up :(
