MR2 Struts in RX-7?
I read on the net a while ago that it was possible to put MR2 front struts in 81-85 RX-7s
It was on the RX7 1st Gen Performance Page http://www.mindspring.net/~crawford2/PERF.HTML but the page is down.
Anyone have info on this??? As I want to replace my struts with an OEM (ie: not highperformance).
So far, I have had trouble finding OEM replacements
Thanks

I know that the MR2 struts are used on the front of the first gen in some applications. I am ordering Tokico Illuminas originally made for an MR2, because they stand up to higher spring rates (>300lbs) than the Illuminas made for the 1st gens.
The trick is, I know these can only be used with camber caster plates because the end of the shafts are a different diameter. They fit the spherical bearing on the C/C plates, but not the stock housings.
Now, as for you wanting OEM replacements... not sure on that... Sorry, I can only answer half the question.

You're not going to find OEM replacement struts. The best you can do is get aftermarket replacements from companies like Monroe. No guarantees on how stiff or soft they will be, though... my experience with Monroe is that their new shocks and struts feel about the same as worn-out OEM stuff. I wouldn't put Monroe junk on my car if you paid me.
Are your struts leaking, or merely flopping around loose? If they're not leaking you could try just changing the shock oil. OEM cartridges (if you still have them in) are wet-type, like the OEM MR2 cartridges. When you unscrew the cartridge gland (?) nut and pull the cartridge out of the strut housing, you actually have access to the shock oil. I've HEARD (not done) of people using motorcycle shock oil in different weights to adjust the stiffness, but I haven't been able to find any info on what weights of oil to start with. But it's apparently a very cheap way to approximate a performance strut, just change to heavier oil.
