Thanks guys for all the input and ideas. Just having an engine model number and year spread is a good start, however, I do not think I have the width of engine bay for a flat six. The engine bay is tapered and starts at about 40" wide and tapers down towards the front so I will have to get a valve cover to valve cover width of the suggested engines, ie:EZ 30 or the EJ 25 to know if they will fit. I want to go IRS and I am wondering if the R160 diff will handle 220 HP in a 1300 lb. car? The reason I want to go with Subaru is the incredible reliability of the engines, smoothness and the fact that a flat 4 will lower the C of G a lot compared to a tall four cylinder. I will have to go with a Nissan or Toyota gearbox and custom length driveshaft and shorter CV's. Any more ideas, cautions or suggestions would be welcome. I have a lot of reasearch to do before I pick up a tool. Thks.

Hello, I am a newbie here and I am on a quest for Subaru info, specifically I am looking at building a Lotus 7 replica from scratch and I would like to put a Subaru engine, trans and diff in it. The car will weigh about 1300 lbs. when done and I would love to have around 200 HP through a 5 speed trans. The Subaru diff seems to be the way to go, R160, I believe and I will need shorter CV axles, but I would like more info on the best engines that are most suitable. I can go turbo, but prefer not to have to row the gearshift through the gears just to get the car up to speed. In other words, suitable torque range, not buzzy. Any ideas would be greatly appreciated. Chris. PS I am a ticketed mechanic and welder.
