turbo 325is

[dailordasailor]

decided not to put it off. I was planning to turbo it this winter and have it be my winter project but once school starts up my paychecks basically end. so now is the time.
its got 100,000 on the odo
plans:
-holset deisel truck turbo
-ebay turbo manifold
-ebay black intercooler
-custom stainless piping
and all the the other goodies including boost controller and all interior gauges. building it cheap then this winter can slowly replace whatever cheap parts need replacing. plan to run low boost on wastegate. plans are to make between 300 and 350 to the wheels.
any helpful comments? good places for neccisary parts cheap? anyone else done this?

Cool. We would love to see your progress!

thanks. one question i do have is about a limited slip diff. how hard to install? and at 350hp will i mess up my open diff? would a used m3 diff work?

[witeshark]

An open diff will never put 300 hp to the tarmac. An LSD can do better, but would need to be rather robust, and anywhere near that hp will still have traction issues.

[nukeduster]

Open diff wont have issues with durability, traction perhaps depending on hp and driving habits but durability shouldnt be affected. As a rule of thumb, a lower geared diff will handle more hp (2.73 vs 3.46). Both in terms of traction and strength of their gears.

not worried about traction at this point. just if itll break getting on it from a 10 roll if see where this projects headed. rwd and good amount of power with light car (stripped to 2400lbs) is bad idea to run from a dig anyhow. so stock dif will work fine until i can get a beter one? where and what to get when its time?
