Need help deciding on Rebuild or Good Replacement
Ok so here's the deal. I have an 87 TII thats been sittin there long enough and need to fix it. Ive done research and talkd to couple ppl in here and can get a good rebuild at a shop for $1400 plus shippin which would be an extra $300. And i wouldnt kno wat else would have to be fixed other than the engine like the transmission....... This past weekend i just went with ma brother to pick up a black SR for his 240 and the swap is very complete and clean. And they happen to have a Turbo S5 complete swap in the warehouse. The swap is exceptionally clean and complete. Has engine, tranny, ecu, harness, a/c, and even power steering and couple more things. Its basically ready to just swap in. I can get it for $1300 or maybe a little less. The guys are yet to do a compression test but lets say its gud. MY QUESTION IS. If the engine's good, wat kind of compression numbers should i look for?? Would yall take that rebuild or go with the full swap?? I know i would have to change fuel pump and something else in the fuel system. THANK YOU FOR YOUR TIME AND HELP

You need to look at the Engine that you Plan on getting.Do NOT rely on Someone saying that it is Good..the engine is a JDM,and most likely has Sat for a Long time,and will need a Rebuild.The Seals are Usually Crap,and they Will go if you just install it and GO..at the least you should "automatically" rebuild a Warehouse Engine...another thing is the NEW engine is an S5 and Won't just Plug and Play into an S4..I suggest you use the Handy Search feature that the Forum has,as this Particular Subject Pops up more than an Old Guy on Viagara!..(and I see no sense in Typing something that is already taking up Forum Space!)..Take care and I hope that you get the car going,,they are a fun Vehicle.You just have to Remember that Maintenance is the Key with an RX7..take care of the car,and it will give you reliability..Neglect it and it Will show you that it IS Boss!..OH,I would actually Rebuild,and not Bother with getting the S5..that way you don't have to figure wiring Etc..and Compression Wise..at LEAST 100 psi.

rebuild what you have. You will have to hassle with s5 motor in an s4 chassis stuff, although having a front clip helps. the main things that are superior about the s5 is the stronger rear iron (more important for high horsepower applications), the superior turbo (which you can easily swap onto an s4), and higher compression rotors which have its own set of advantages and disadvantages.
if you had an s5 already I would be more inclined to say go for it, but it's not worth the hassle

No you also need to redo the s5 wiring yourself. Every last connection. Looking at wiring diagrams, cutting and splicing everything. It is not compatible. s5 into s4 is not easy. An s4 turbo engine would be better.
A typical rebuild is $3k. You might be able to get a deal for $2k. Below that there will be compromises. Replacing the housings or anything else beyond the seals will cost extra. Any replacement engine you get will be $1000-$1500 and it'll be a gamble. Often you'll have to rebuild it. I'd either go to a reputable company that does rebuilds and pay the $3k or ask around a lot to see if you can find some guy with a good rep and save some money. If you've got lots of time, an engine hoist, an engine stand, a clean dedicated garage, etc., etc. you could do it yourself too. But the seals will still cost a lot.
