Nice kill, the perfect car to mod...hehe TURBO TIME!!!
Look what I picked up!!
- Thread starter VividMP5
- Start date

- '13 CWP MS3 & '16 Mazda6 GT
lol mcstrut?
Soon, but not too soon! $$$
The 7's starting to smoke some but it's still manageable, not a good sign. Usually the day after if I drive it hard, it'll do that the next day. But if I just drive it normally, it's ok. But it's definetly in store!

you mean MacPherson strut. FD's are front and rear independent double wishbone suspension, same as you miata. And lots of sports cars use MacPherson setupaMaff said:

The smoking issue had dissapated. I thought that maybe one night when I get home after driving the 7, I would let it idle for a few minutes to burn off some oil (because of the oil being injected into the rotor, and the more you step on it, the more oil is injected) and low and behold, no more smoke in the morning!! Before it was about 10mins of thick, white smoke!!
Another thing, I had an idle issue...When I drove the car with AC running, when coming to a stop, the idle would drop and stall out the car. Before I would just turn off the AC before coming to stop, but now, it's all good.
The fix....I changed out the ECU. Apparantly, the transistor in the ECU that controls the Bypass Air Control (BAC) valve (it controls the idle when the engine is under load, ex. AC, headlights) goes bad, or because of soldering issue. You can either resolder a new transistor or get an ECU and pray that it works. Well, since I don't have any knowledge of what goes where and thinking about messing with the ECU freaks me out, I decided to go with the later.
If any of you have the same issue and want to solder your own transistor, you can get it at Radio Shack...#276-2068 TIP120 Darlington Transistor, it's only a few bucks.
But always check your TPS first, test it and adjust it before going this route. Also check you BAC valve, make sure it's working.
Still loving my 7!!

RX7 Vert Update! One guess....one letter, "T"
Hi all!
I haven't post about the 7 in awhile but some good and bad news. Back in January, the engine seized up, the car just wouldn't turn over, I knew that the battery was good(i'd just replaced it)so I came to the conclusion that the starter was bad so I took it out and swapped it with another one and still nothing. The following day I had it towed to my friend's shop to have him check it over, he tried to turn it manually and couldn't, so he came to the conclusion that the engine was seized! Now I was in a delima.... rebuilt, find a used NA engine or used JDM turbo swap! After some deliberation, I've decided to bite the bullite, and do a turbo swap!!
Now, how the hell am I going to do this? This wasn't an easy matter, but after talking with some people and research, I got info on how to do a turbo swap on the RX7. First, you need to figure out if you're doing an S4(86-88)turbo swap, or S5(89-91), because if you're doing an S4 swap, everything has to be from an S4 turbo, with S5 the same. Since I have a 1990 RX7, I did a S5 swap without the rear differential and halfshaft for the time being. So here it is...
You need a turbo engine(longblock), tranny, driveshaft modified to fit a NA differential or if you want to do a complete swap, you need the turbo differential(has LSD), and halfshafts(beefier than NA)with all of the turbo N370 electronics(AFM, MAP, ECU), and turbo harness, throttle cable(S4 will work as well), Turbo hood(if you're running stock intercooler), FD fuel pump(for better flow)apparently it's better than the FC turbos and at least a boost gauge(the stock one that came with the turbo gauge sucks). Also, it might be a good idea to clean the injectors. Now there are two ways to approach this, first, and I would suggest this, is to get a half cut from an importer, so you have everything you need to do the turbo swap, sometime you can even get a rearend and turbo body kit from them as well. Or second, find all of the parts separately to do the swap, which can be very time consuming and you don't know if the part you're getting are worth a toss, which is why it took me sooooo long to finish. The first engine that I got from (JDM Racing Motors) was s***!! One of the rotors had no compression, so I had to get another one. I'll try to put up some pics of the finished project later.
PS Try not to get an engine from Canada!! I had a very expensive lesson!! JDM Racing Motors sucks!!!!!

LOL, thanks for getting back to me
Got a big pic of it?
Sorry to hear of the troubles you've had.
