M50 swap dinan throttle body 3.5HFM
 
hey guys... so I heard doing the m50 swap on an s52 motor will lose torque? is it not worth doing? I'm also putting the dinan BBTB on it with a 3.5 HFM and a 3.5 dinan intake. my rev limit is still at 6500 so idk if I should even do all those things. FYI I got all those parts free except for m50 manifold.

The M50 manifold losses power below about 4000 RPM, increases it above 4000.

When we put a Turner Stage 4 kit on our M Roadster (S52) we kept the stock manifold since the car is street driven only.

For a track car, I would put the M50 manifold on.

if I do the m50 swap do I have to get a chip to make it go to 7k rpm?
if I do what's the best chip to put on it I know there's quit a few of them out there

I don't think so.

I like the Turner/Conforti.

can u tell me what need to get to do the asc delete? I already have 3.5HFM and 3.5 intake and a dinan bbtb... I heard it was just a boot that I need to get or something I'm not sure

I prefer to keep teh ASC system intact for a street car.

For a pure track car, IIRC, it is just a connector hose that replaces the ASC section.

wouldn't it create a bottle neck affect if the asc isn't deleted?

Pinecone 02-14-2012 11:17 AM

Yes, but the ASC may very well save your car.

marksM3 02-14-2012 01:43 PM

save my car how? all it does is close the throttle when wheels are spinning

Pinecone 02-15-2012 06:48 AM

Which may keep the car from swapping ends and sliding off the road sideways or backwards.

lol would of been helpful when I wrecked the car. guess just gotta get better tires this time

Pinecone 02-19-2012 04:11 AM

Better tires, driving schools, and using the ASC when on the street.

I race and teach HP driving at local tracks. I leave ASC/DSC ON, when on the street. OFF at the track.

marksM3 02-19-2012 04:16 AM

driving schools for what? lol

Pinecone 02-20-2012 05:13 AM

For the most important part of the performance package. The nut behind the wheel.
