13b Starlet
 
So am doing a engine swap on the starlet. Its my first rotary swap and am wondering what modifications i need to do just to actually fit the engine. I searched a lot but there isn't much info anywhere about this type of swap. So just help me out

my brother has a starlet and the typical way people do them is to cut off the stock engine mounts,put i think it's 1" or 2" square steel spacer between the subframe and chassis and weld the engine mounts like they are on a 1st gen rx7.depending on where you put it you might have to cut from the firewall for the slave cylinder...hope it helps

So i have cut of the stock engine mounts, now i just have to find a 1" or 2" square steel spacer like you have said.
About the pics i will take some pics later today if I can, and upload them.
Thanks for the advice.

You would be better off using square aluminum bar stock, unless you use solid steel because if you use square steel tubing it tends to give with time. Now if you do decide to use the square steel tubing reinforce it using round tubing in the area where you drill the holes and weld, this will stiffen it up. The reason for this spacer is for clearance of steering rack. If your going carb. you will need to be as plum as possible. EFI well it really doesn't have to be perfect. Thats where the clutch slave cylinder comes into play because it hits the firewall, the fix for this is to bang the hell out of the firewall (not to pretty) or cut/notch and weld/repaint. Tranny and motor xmember will need to be scratch built to suit plum. If your creativity makes it happen differently I'm all forward for it just post pics so we can all see. I hope this will help you.
