Hello all you very knowlegable people of the forum
(No joke I've had lots of help here)

Im thinking of buying a gsl-se, and I was wondering what to look for. Is the fuel injection ok on this model?

if anybody has links to info that would be great.

This would be my first RX-7 and my first car.

anything would be great

I have My first GSL-SE and I love it. I am a computer guy and understand FI and have less understanding of carbs(but it is getting better) easy warmups, easy cold weather startups. I love the SE for the "normal" bolt pattern, larger brakes, LSD. Not to mention the added torque of the 13b.

I love my -SE. The EFI (or EGI as mazda likes to call it) is pretty decent. It uses a pair of 680cc/min (~65lb/hr - had to convert for my megasquirt config ) injectors as opposed to the staged 4x550cc/min injectors in the 2nd gen NA motors, my opinion is that this is perfectly ok for most people until you start really modding the hell out of the engine, at that point you should be going aftermarket EFI ECU anyway. But, the GSL-SE's came with:
premium sound,
ac,
power steering,
the better air/oil cooler,
4 wheel power assisted vented disc brakes,
LSD,
~4.07 final drive ratio,
14" alloy wheels,
upgraded suspension,
lowerd rear trailing arm mounts (better rear end geometry, all rotaries incorperated this change from the ~84 GSL-SE on),
4x4.5 bolt pattern (REAL EASY to find rims for)

and a partidge in a 13b

Not ALL of the SE's came with power sterring or AC.
I have seen some that were ordered with out it but most came with it. That also goes for the sunroof.

Well, I thought the SE came with 2 720cc injectors..

Anyone car to tell us??? i am not 100% sure..

Just to be a nitpick

2nd-gen N/As had 480cc/min injectors - the T2s have the 550cc jobbies. The stock GSL-SE injectors should be good for 200hp or so at the flywheel.

All '84-85 chassis have the lowered trailing arm mounts... basically it makes the car understeer more. (booo ) The change was to increase "roll understeer" - as the car leans, the rear axle steers the car towards the outside of the turn.

There were only two options on the GSL-SE - leather interior, and power steering. My GSL has all the goodies that a GSL-SE has... well, except for the 13B engine and bigger brakes

Speaking of engines... how's that MegaSquirt coming along?

From my experience the 84's came with 680's and the 85's with the 720's

If you think that two injectors are hard to keep track of try four!

Also when lookin at any RX-7, look for signs of rust in the rear wheel wells, from both inside and oustide the car (remove the inside bins)

Check the motor to see if the 6 ports move freely and not locked up.
Check for any smoke (Blue or White) coming from the exhaust on startup.
check every **** and button to make sure they work.
wipers, turn signals. heater/vent controls.

Hm, is there an easy way to verify that? I don't want to botch the flow rate while programming my ecu


Oh, and the Megasquirt is coming along, I'm mostly planning the install right now. I really need to sit down and solder the thing together. Hopefully this weekend. Then I can start working it into the car's stock harness. I was thinking about building a relay box so I can switch between the two ECU's... Heh, always something with me

Edit:
ok, well I plugged the bigger injector numbers into the megasquirt config program and the pulsewidth changed from 3.22ms to 3.08ms, so it's probably not that big of a deal

Just like any other older car, IMO, the first consideration should be the condition of the body. Do a search to find out more info on this subject, but basically look for anything more than surface rust on the bottoms of the doors, under the storage bins, as well as under the car, then look down the both sides of the car for signs of collision repair.

Also make sure when you check the car out you have the opportunity to start it both when it is cold, and later restart it when the car has reached normal operating temperature (it should start easily each time). Also, stand behind the car and look at the appearance of the exhaust as someone else revs the engine a couple of times. Blue smoke is oil, black is normally fuel.

Finally the EGI of the GSL-SE is not without some quirks, here is a link regarding some of those issues and their fixes from a 1st gen guru: http://mrmazda.members.atlantic.net/gslseidle.html

good luck

Both my 84 and 85 original injectors were sent off to R/C for cleaning, and they came back with flow rates of 680 and 720. From hearing both numbers back and forth, I can only figure it was year dependent.
