-6 Original Motor Convert? Options

[1973914]

Hi everyone! This is a great source that i look at daily. Have a question for the experts.

Car: 73 2.0 with original motor, Weber 40 carbs (but have fully functional injection in boxes - wanted to play with carbs -sadistic), MSD 6AL ignition, Holley fuel pump, all braided fuel lines, inline fuel filter, headers, supertrapp, custom cage (driver compartment only right now with side bars), fuel cell, remote cooler up front with -10/AN lines running center of car, corbeau seats w/5-point harness, koni adjustables all around- 200lb springs in the rear, stock torsion bars (as far as i know)stock brake calipers, pagid orange pads, 19mm master cylinder, braided lines, fiber hoods and bumpers, includng the GT front end with cutouts for the correct shaped and ducted cooler, 2.0 fuchs w/ 205/50/15 kuhmo rubber and a set of 15x7 panasports (race) when i get the courage to flare. Car is almost exclusively used for track and autocross, although i plan to do an occasional weekend fun run starting soon (will register for this purpose - it isnt currently). Thats all i can think of to describe - trying not to get flamed for poorly formed question. (IMG:style_emoticons/default/wink.gif)

Opportunity: Original 2.0 from 6 cylinder car in family (read - free) with good heat exhangers and muffler. Motor has been sitting for 10 years in dry and controlled conditions, when father pulled it and put it an IMSA race motor and generally turned the car into a monster; he races the car in several venues.

Question: Im sure this question has been asked before, but what kind of efforts would be needed to install the 2.0. How much are top end parts, assuming the bottom is ok and the end result would be a "warmed" stock motor for the HSR 2.0 class, with an eye toward longevity? What about conversion costs (motor only at first)?

Any advice/comments would be really appreciated!

Bill

EDIT - knew i would miss something! Side shifter with shortened 4th and 5th.
