this must be a relatively small forum going on here or something... not many posts in the rx-7 side. not many posts in general. oh well that's not the problem here...

so if any of the (47 and counting) people that have viewed my post about my flooded 86 rx7 noticed, i'm looking to swap out my 13b for another engine. obviously another nicely rebuilt will bolt right in. and i keep hearing about all those people putting v8's and other non-mazda motors in your cars. (i'll stay away from that argument in this post) what about a 13b-13bt swap? what kind of difficulty am i looking at?

obviously ecu, hood, gauges (exhaust?) will need to be swapped too. what am i looking at as far as cutting things, rerouting lines? anybody done this swap? transmission from 13bt fit nicely too?

well, i was lookin into the same for my vert.

i am gonna need ECU, 13BT Wiring Harness, Motor, Tranny, Rearend, I think you can adapt the N/A Exhaust to fit the Downpipe. You dont need the hood if your going Front mount IC. i was lookin at about a week or 2 to swap everything, and modifications. I was thinking of going Front Mount IC, Bigger Turbo, Bigger Injectors, Haltech Stand Alone, Electronic Boost Controller. but if u wanta do a N/A to Turbo Engine Swap, Look at a week to do.

ok fuel management, oil "management" (is that the word for it? lol), wastegates, BOV.... come standard if i were to just buy an '87 13bt (do they make them in 86 turbo?) i'm assuming it's not being boosted very high, maybe 7psi or something, since nobody goes out to buy FMU's, BOV's, etc when purchasing a stock turbo mazda...

any experience with just the 13bt's? not necessarily swapping, but insider info on what i should/could keep and what i should look into upgrading?

aaaaanndd... "rear end" what all do i need? what's different, what needs to stay?

i'm not looking for larger turbo, injectors, or anything... and probably going to want to keep top-mount IC... i just really want a stock turbo that's all :)

I was told that the stock N/A Rearend wont hold up to turbo abuse. i dunno, i guess they were talkin about racing. It also might have different gearing than the TII. I thought all S4 13BT's were the same. Ill need to do some reasearch on that. im guessing you can use any year motor if u get the harness and ECU with it.
