I am planning on installing my HY35 and W140 Euro Manifold onto my stock 1987 300TDT. I would like to install this and get some numbers; at least do some runs of my iPhone's "Dynolicious" program which has accurately assessed my car at 145HP and clocks my 0-60. Better than nothing! Then I would like to add a 3" straight pipe and run numbers again. All of which will be documented on this site.

This is my first time doing something like this. I will be doing it at a friends shop most likely and he knows quite a bit about turbos and is a good mechanic. I also have access to a Fab shop and people that can weld, cut, plasma table, shear, brake, etc.

Parts list (feel free to add):

- Gasket for Exhaust Manifold to Head
- Gasket for Turbo to Manifold
- Bolts and Nuts for Manifold and Turbo (Do I need these?)

Questions:

- Since the Euro manifold put the Turbo on top, will I need to re-clock the turbo for ports to aim proper direction?

- How will I need to accommodate for an oil line? My guess is the the stock ones will not line up.

- What is the best way to connect the 4" downpipe to my existing exhaust?

- On the intake size, where can I find the tubing I need to go from Air Filter to Intake Port?

- Eventually I will put in an Intercooler, but in the meantime, how do I get the Crossover pipe to connect to HY35?

It is your project, DO IT THE WAY YOU WANT TO!

Take as much insight as you can from EVERYONE and toss out the BULLSHIT and bench racing and use what is viable to assist you in your endeavor.

Sometimes it just takes some good old fashioned trial and error. Everyone builds their engine for their own liking. If you want a car to drive on the streets and have some low end grunt then that is your goal. If you want to see how much power you can squeeze from these engines then more power to you, sometimes it takes compromise. Personally I would like to see the latter and applaud those that push the envelope by fabbing custom parts and making more power than was thought possible.

On my project I did quite a bit of research, but was still unsure if the exhaust housing on the turbo was correct...well after hooking up the gauges it shows that the EMP and boost look really good and play well together.

I for one like to be the underdog and do what others say can't and won't work and love to prove them wrong.

Good luck!
