A little background on my fd:

1993 stock LHD w/ peter ferrell exhaust.
recently upgraded to greddy fmic, koyo rad, hks bov, hks intake.

I got those upgrades done a couple of weeks ago, and I've been having issues with air in my coolant (low coolant light comes on when cold, overflows when hot). So about half an hour ago I decided to go to a local shop to do a proper coolant flush to get the air out. I let my car warm up for approximately 7 minutes (time it takes to finish a smoke), left my house, and after about 4 km I heard a loud "pop" and lost all boost. So I turned around and came home.

So I guess my main question now is...should I replace my blown turbo or just get a gargantuan single? Also, I'd like to find a shop to completely look over the whole car and tell me what else I should do to keep it running properly after the turbo issue is resolved.

I'm posting this in the canadian forum because I'm pretty well useless when it comes to doing work on my car and I'm hoping to find a good trustworthy shop to get my car running properly again.

I'm in the Brampton/Caledon area, and most shops I know of around here are complete hacks. Help me please!

 

Did you check all your vacuum hoses first?

 

the one attached to the bov seems like it was pretty soft and I am waiting for a stiffer one to come in. it seems like it sucked itself shut sometimes.

 

I don't have an fd. But I'm also in Caledon, and have an fc.

I would say go full single, it doesn't have to be huge, but now is definitely the time to do it. But yah, I would make sure to get the car checked out, bc it could be anything. Also, get a powerfc asap.

 

Do you know of any decent shops around here? I'm boycotting my usual shop and I wanna start fresh with someone who actually understands rx7's. Or for that matter, would you mind coming to have a look at it? I'm pretty desperate at this point and just want it back on the road before it starts getting too cold.

 

Did it happen just cruising or WOT? Does the car idle ok? What exactly is no boost? (0,1,2 psi etc.?) Have you checked if any of the intercooler pipes or the BOV's popped off? Check the obvious first, don't just assume your turbo's are dead. You'd probably have other issues like coolant and oil leaks if you had a blown turbo.

If your car is still relatively stock, its not cheap to go single but I would definitely suggest you consider it with your available funds. However, you don't need to go gargantuan single. If you need help with this, let me know.

There is a list of known rotary shops here...

Did you check All your boost piping when a pipe pops off it makes a big pop sound

 

I'm not sure how reliable the boost gauge is but it goes up to 1 or 2 psi. I didn't do a thorough check but all the piping seems ok. I was just cruising, and it happened while I was going roughly 70-80 km/h, in third gear. Like I said, I'm pretty much useless when it comes to doing work myself so I'd rather just pay someone else to do it properly.

Thanks for the info, I'll definitely pm you if I need anything.

Cheers.

 

I've been driving diesel trucks for about 10 years now and I've had boost piping blow a couple of times on one of my trucks. It didn't sound as low-toned on the fd, it sounded more like a cherry bomb blowing up under my hood.

Also, I forgot to mention earlier that the previous time I drove my car the turbo was making a weird high-pitched whistle sound. Kind of like stretching the mouth of a balloon and letting the air out slowly, or farting with a clenched ***.

 

Have you tried to boost since then? Sometimes the twins get an issue where it will only boost a few pounds and it has to do with the complicated twin control system. But usually it will boost fine but then if you let off and stab it again, it will only make a few pounds.

Owning an FD with sequential twins, you better start learning how to do some things yourself ^_^. If you really think its your turbo's you can always pull off the intakes and check for play and see if they spin freely. That way you know if your turbo's are ok.

BTW, the hks intake makes the turbo's have a unique sound.

I know the issue you're talking about and that's not what's happening. The turbo is just plain dead. Mind you, I haven't been home since I first posted this thread so I haven't even had a very good look at it.

I do know how to do basic work. I run a landscaping company and a disposal company so I try to do most machine and truck maintenance myself. The main problem is time. I get about 5 hours of sleep every night and I don't plan on cutting that time any shorter. I don't know much about this car yet, but by no means am I mechanically retarded.

I'd like to have it running efficiently by labour day weekend. I wanted to replace the rims and tires this month but I guess that'll have to wait a bit longer.

 

Are you running a cat? It's not unheard of for the cat to clog up so much that you don't get any boost.

I guess you need to decide if you want to try to figure it out yourself or just take it to a known shop to take care of it for you.

I am running a cat, but I've been considering installing an exhaust dump valve.

 

My cat got plugged and did the same thing

when my piping comes off it sounds like a cherry bomb lmao

 

I have a question, I have a t04, 62-1 ball bearing turbo, and i've had the car sitting close to 2 years now. I originally parked it due to a bad motor, (water in front rotor housing)

now the turbo wont spin freely, is this an issue? is my turbo okay, or what's going on to the turbo?

Let me know if anyone knows anything.
