I'm looking into buying two rx7s. Both.together. and the 89 gtus is kind of rusted.bad. the person was goin to swap everything to 86. Motor tranny so forth. Now. I was wondering. If you take Taillights from 89 as well as front bumper. How much work is needed. And will the fenders have to go over as well?

Its easiest (well all things considered) to swap EVERYTHING. You'll need to gut the 86 to an empty shell then swap every last component from the 89. ALL the wiring and computers relays and such. That's the front harness, rear harness, dash harness, both door harnesses, and engine (emissions) harness and battery harness. You can keep the brake and clutch hydraulic systems but the brake and clutch switches mounted to the pedals will need to be swapped. The fuel pump connectors are the same so no need there. Id inly swap brakes if your 86 is a 4 bolt hub or if the donor has 4 pistonand the 86 doesn't. It is a bit of time consuming and labor intensive but its the best way to make it all work. You can ignore the auto seatbelt crap if the 89donor has it. I've done it before took about a week. Download both service manuals (86-88 and 89-91) it'll help. Be careful with the wiring retainers to be able to reuse as many as possible

If you take the front bumper, you might as well take all door and fender trim and the rear bumper. Otherwise, you'll have mismatched molding.

Well as far as I know. The 86 is only missing the motor and trans. The harnesses can't stay with the motor. The motor from the 89 is not original. It's a used with like 50 k on it.

I was gonna leave door molding off. Prolly just stick with bumper molds. Leave sides plain like the 87 I had

My guess is that the harness will have to be swapped inorder to run the new engine properly

dimitry04

My harnesses remark was a ? Btw

dimitry04

but thanks for the insight on harnesses needing swapped. i would have never thought to. unless schaft said too. he lives close if you couldnt tell and is i think dying to help. only cuz he gets stuff i think. lmao. jk. sooo. about the harnesses.. do you have to take out dash and stuff too. or no? im assuming ecu has to go as well??

all wiring will need to be swapped.

everything changed in late 88.

dimitry04

ok. well.. hows the dash situation then. will itneed removed. or it can be only thing to stay??

stevensimon

you can use old dash if you want as long as you pull it and swap all the wiring.

s5 dash is better though.

dimitry04

i was thinking swapping instrument cluster. from s5 cuz i think it goes to 160??idk. what are differences between the two dashes

First thing is we need to find were to put the cars while we do this

dimitry04

ill just do a storage place i guess. where exactly is that one by you. and would they ok with us doing work on cars there?

^This.^

Also, swap the trim. It looks better that way

dimitry04

When it.comes to pulling motor and putting it in the other car. Do I have to seperate the tranny from motor? Or is it possible to do without doing that

they can be pulled together...

dimitry04

haha sorry i jus never quite did this before. just wanna make sure.

dimitry04

im sure this can be found. but if i search i cant find it. but whats considered good compression and what not. im gonna do a test before i get cars.
