Well, I finally fixed the car and got it to run (with a 1984 tranny), new clutch, surfaced flywheel.

Cool little car!

Do you think I should change the oil right away to make sure the previous owned wasn't slacking? Anything else I need to check?

Opened up the carb, looks like it has a very fresh filter...

But something disgusted me today under a closer inspection - someone installed a "champion" oil filter! That must go!

Anyhow, pretty fast car, fun to corner. I like it, hopefully it will last

 

change all fluids: oil, tranny, diff, and radiator. i run marvel mystery oil as a premix just to be on the safe side and keep the apex seals happy. probably will want to change the fuel filter.

 

Well, the tranny was just dropped, so the tranny fluid is changed along with ?rear?.

I'm going to change the oil next weekend. Any suggestions? I know that everyone has their own theory about the brand and thickness, but what's the concensus? I use 10w-30 in my turbo impreza, trisynthetic. I doubt I want synthetic oil in the RX-7...

 

I've typed it before, Ill type it again...Only cause I feel nice, next time search, its there, I know, I typed it .

As for the engine oil, 20W-50, non-synthetic. No synthetics because as I hear it (kind of a undecided/unproven reason), synthetics dont burn clean enough, and leave too much carbon (since the engines inject oil into the carb float bowls to burn in the gas). You make your own decisions, but I personally do not run synthetic, mainly duw to cost, but also because of this exact point.

Heres what I run:

Engine: Castrol 20W-50
Tranny: RedLine MT-90
Rear End: RedLine 75W-90

Oh, and if you dont know if you have a LSD or not, if its an 81-85 and has rear disc, thats usually a dead give away that its LSD. If its an 84-85 GSL-SE, Its LSD also. I dont know to much about pre 81 cars if thats what you have...Sorry.

The general consensus over the years has been not to run synthetic due to the reasons RotarMotar mentioned. However, it's been proven that certain synthetics (Mobil 1) are perfectly safe for rotary use even when retaining the oil injection. But, to be on the safe side you can disable the oil injection and run two-stroke pre-mix in the fuel tank instead.

Personally, I run mineral (Penrite HPR30) because of the cost and the fact that I change it every 4000km's.

 

Thanks guys, great info. Its actually a 5spd 1983 GSL, as to wether it has the LSD - I gotta check in the morning

 

If its a GSL, its got LSD .

PS - I have an 83 5 Speed GSL as well. Mine has an engine out of an 84, not the tranny though .

 

The engine has 92,000 original miles. I don't know why I am mentioning that, but my friend says thats pretty good for an almost 20 year old car...

 

first time driving a 1st gen RX7? Bet your cheeks hurt from all that grinning...

 

That is decently good mileage for your car. I have 80,000 original miles on my 83 . Theres 205,000 on my 85 GSL, 200,000 on the 85 GSL-SE, and 180,000 on the 84 GS .

wow! I only hope my car will last that long, its my fun daily driver, my other car is not that legal on the streets

 

not that legal eh? thats usually a black and white line. is your impreza 2.2 model or the rs (previous to conversion).

 

How much marvel mystery do you put in it. And whats premix mean to be on the safe side?

 

He means (I assume) that he has removed the OMP (oil metering pump) and runs pre-mix (like a weed whacker) in the gas tank. A few people I have heard from are doing this. Its more precise control that way, I guess. I was thinking of it myself, Im just not sure Im ready to go that far yet .

i've got an '83 GSL as well.. with i '84 tranny i think. rx7passion would be able to tell me for sure
