[JonPowell]

I dont really see that it would be all that hard. I have no actual esperience with it though.

If you do the RB swap in your 240. Go to http://www.supertunermotorsports.com. They specialize in that and know what they are doing. They have kits for the swap that, well if you want a good stable car youd better plan on getting one or you'll run into a lot of problems soon down the road. Try to get a 5-speed.

What kind of problems would you run into if you dont get their mount kit? I am curious because I used the stock R33 crossemmber, mounts and such and dont want to worry..

With there kit, It lowers the whole motor a little. Not much, but enough to make a difference. You wont have to modify your hood. It also move the shifter (and motor) into the correct spot which ends up being like an inch and a half closer to the driver thus giving you a better wieght ratio. By lowering the motor you will run into problems with the sway bar. Included in the kit are spacers to move the sway bar down so it does not interfere with the oil pan, and most importantly to me they include spacers for the transmission to lower it so it doesnt make contact with the underbody of the car creating not so good vibrations. It also lines up the driveshaft with the rear differential better to prevent driveshaft failure. They make a 3" downpipe that gives plenty of room between that and the steering shaft. Look you can do the swap without the kit. But with all things concidered would you want to risk one hell of a car and a lot of work. The kit is used with the R33 crossmember. They have diffenent levels of this kit, so if you have somestuff taken care of you dont need you dont have to pay for it. Check out there site.
