Hi everyone...I'm sure this has been answered before, and I'm sorry if you guys are tired of these types of questions, but I searched the forum and couldn't find a specific answer as to what information and possible suggestions and/or alternatives I need.

Ok, to begin with, I am posting this for a lazy freind of mine who has a 1995 Nissan 200SX SE-R 5MT. I am a Honda H22A VTEC man, but I am pretty familiar with alot of Nissan terms and technology as alot of my buddies own them. (240's mostly) I am also very mechanically inclined when it comes to automobiles.

The car has 225,000 miles on it, and the transmission has finally lost it's 5th gear completely and also the A/C compressor has locked up....So, instead of spending over $1200 to get all this fixed, (and possibly have another failure after that) we have decided it would be best to just go ahead and swap a new engine in the car and at the same time upgrade to a turbo, or possibly one of the Variable valve and lift timing engines. (I need someone to keep up with me

)

The only problem is, the transmission and clutch engagement setup is a cable type. The turbo engine is supposedly a hydraulic setup (according to him).

Now here is my first couple of questions:

How much of a task is it to convert the car over to a hydraulic apparatus? Is there any cutting/fabrication involved in installing the clutch master cylinder and new clutch pedal mechanism (if required)to the firewall and whatnot? How about the hardlines? What car would I need to rob at the junkyard to obtain all the neccessary parts for the hydraulic clutch? A G20?
If it is a chore, then would it be recommended to buy another cable transmission and just bolt it up to the turbo/NA engine? I know a stronger aftermarket pressure plate and clutch would be a necessity, but are they available?

Now for some more questions concerning the ECM wiring AND the accessory compatability:

What extra wires and ECM pins are needed for the two engines?

I would think a knock sensor wire would need to be added and possibly the extension of the MAF/MAP? sensor wire, and of course the VVT-L electronics for the NA engine. Anything else?

Does the turbo or VVT-L engine use different fuel injectors than the SR20DE? Low/high impedance; peak and hold/saturated? Of course a larger fuel pump would be installed.

Anything regarding distributor wiring? I don't know if the VVT-L engine uses coil on plug or not?

Also, does the A/C compressor have the same fittings as the B14 high and low pressure lines?

Power steering pump fittings the same? Alternator?

Also, will a sidemount intercooler from a Silvia work and fit on the SER? I really don't want to cut a big hole in his hood for the top mount to breathe.

Will I need to upgrade the CV halfshafts to handle the additional horsepower and torque of either of the engines?

Perhaps these is a write up article somewhere on how to perform this engine swap that would tell me everything I just asked?

Anyways, thank you very much for taking the time to look at this and I know how frustrating repeating questions can be, but like I said, I haven't found anything that answers my questions specificall, nor any suggestions or alternatives.

Thanks again,
Mack
