91 S5 turbo swap (Help Please)

I know theres alot of this questions that has been asked on here but I'm new here and don't really understand this forum thing

I have a 91 n/a fc3s the engine went out. I was looking into engine swap and thinking about the REW motor but i know theres alot of work needed to go into it. Then i was looking on ebay and found some S5 turbo motor with coils and trans and everything and i was wonder if this would be a complete drop in? or would it take a few changes? i wouldnt be surprised that it would need modifying

Jdm Mazda Rx7 13B-T Engine S5 Jdm 13BT S4 Engine FC 13B-T Engine | eBay

89 92 MAZDA RX7 FC 13BTTURBO ENGINE JDM MAZDA RX-7 13B FC3S TURBO ROTORY ENGINE | eBay

These are the two im looking at and they seem great but im not sure if this is good or in running condition...etc.

If there are things please tell me in clear detail if possible. I have experience with working on classic muscle cars but not much with these rx7's. I love my car and if i dont figure something out then ill lose my car

Yes, the S5 turbo engine is a complete bolt in, if you have all the parts. See these links in the FAQ which thoroughly document turbo swaps:


Can I swap a Turbo engine/Jspec engine/13BT/etc into my Non Turbo?
Yes, check these links:

How do I add a turbo to my NA 13B?
What Turbo kits can I add onto my non turbo RX-7?
There are no longer kits formally made at the time of this post, however there are companies from time to time that do make available non turbo to Turbo Kits. Because most of these companies stop building the kits, or go out of business in short time, it is impossible to keep active links for them.

Most people that turbo a non turbo make their own kits:

All great information. ^

'Japan2LA' is a reputable JDM engine importer on this forum. Send him a PM for a known running engine.

I ordered a JDM engine from some "no-name" company years ago. The engine arrived and needed to be rebuilt. :-/
