almost 130K on first motor with heavy mods. just blew a seal on each rotor, which sux. my motor is going to be replaced by a street-spec one from RP along with many more goodies-including power FC. now maybe i can run high boost w/o my motor going.......shudda' done the boost control or management sooner....oh well.....

I blow a typical puff of oil smoke on cold startup but between changes every 1500-2000
miles I never have to add any.
I have heard of guys using a quart or more every 500-1000 miles even running their
cars easy ??

85k fearing rebuild soon, but engine still running strong.

My engine took the big shiter at 71k.

my 93 had 120 when it was stolen(motor was blown) .the new motor has 40.

there was some guy on clubsi with a tII that said he has gone through 6-7 motors in 3 yrs. i dont know if he is on here but he sounds like an idiot to me. warmup? whats that? :rolleyes:

Just turned 60K Still running strong. No rebuilds yet

36K,Original motor and turbos

:confused:
You do know that between the F & L marks on the dipstick = 1.6 US quarts and you should add a qt any time the level is below 1/3 on the hatched area don't you? The Oil Metering Pump should be injecting 1 qt in 1000-1500 miles depending on driving style.
Mine consumes about 1qt/450mi due to leaky Turbo Oil seals.

My FD has 81K and runs like a bandit, 11-8-11, 16 at idle.

original motor 39600 miles

engine life
 

I had 4 rx7's over the years. Everyone had the original motor. !st gen until 120,000 miles. 2nd gen from 28,000 to 98,000 miles. No problems and I had intake, exhaust and upped the boost to 10.5 lbs. with a pfc f-con ecu piggy back. 3rd gen until 45,000 miles then sold it.

Now- mint fd with 26,000 miles. Runs lile a champ. Play it safe- 94 octane with premix and no mods. But, that may change soon.:p:

Miles on engine...
 

10,206 original miles on engine and chassis. My garage queen. :D

god damn, talk about being born under a bad sign... i've owned my '93 base FD for almost 6 years now and am on my 6th motor... and just today it started idling *really* low for no apparent reason, only 284 miles since it was put in... my fingers are crossed, but i'm getting used to dropping in new motors as often as i have to purchase new tires..

80k and still running strong :D

WTF??? :confused:

Bought my 2nd FD over two years ago with approx. 70000mi. The engine gave up at around 106K in Sept.2001.Got the new engine intalled in Dec.2001 and have since put on 3K. So far so good. My fingers are always crossed.

I have 127K original and runs pretty good. I'm getting ready for a rebuild though. 93' touring

Original motor w/82k on my 93 R-1, completely bone stock...not a guage in sight.

My secondary turbo is starting to blow a decent amount of oil though :(

Just went over 80k on the original motor. Still pulls like a mofo'.
Just had to replace the turbos last month.

I've had it for 4 years and installed the mod's listed below when I
first got it (had 35k miles when I got it). I consistently run her hard
and run 13.5PSI I guess I've just been lucky! :D :D


Knock on wood!!!

93 R1 63k 10-8-10
I've noticed a lot of people replacing their engines due to the "coolant" seals". How can I tell if mine are going bad and how can I prevent this?

Reading these posts makes me feel next to stupid for wanting to buy my first R1 with 100k on the odometer.

im kinda new to all this, so may I ask, what is premix? I hear you guys saying it alot.....

Had a 93 with engine replaced at 90k and turbo's at 110 later sold with 138k and no problems. Currently have a 94 with 59k orignal motor but replacing the turbo's now but was running 14lbs of boost. Also have a 93 with 39k original motor. Premix is just 2 cycle oil mixed with each tank of gas usually 4 oz's per tank as extra percaution for to protect the seals on the rotors. If the Oil metering pump is working its not necessary just recommended for extra protection.

Don't know all the circumstances as I just bought it, However 1993 RX-7 # 9 in Canada, 3rd rebuild I cracked 2 apex seals driving it home Current car milage 28,000Kms. or 17,500Miles

93 montego blue touring. 1st motor went at 53,000. Due to overheat cuz of broken AST toasting o-rings and water housing gaskets. Turbos were also rebuilt. Currently 2000 miles on rebuilt 2nd motor. I hope this one will last. I heard the pre-mix is good but is it really necessary if i change the oil every 2000 miles. I've heard some say it only helps but isn't necessary. Then others say don't even bother using it since you change the oil every 2000. Hmmmm?
