6 port NA made turbo

88 FC3S Vert

Bought the car recently so much about it isn't really known. What I can say is that it has been driving fine. This began today right after a drive home from work exiting the highway.

Odometer reads 123k however previous owner stated motor was around 75-80k. Turbo kit is newer from what I can tell has maybe 5000 miles on it.



Please let me know unfortunately this is my daily and need this fixed ASAP. Having this car as a daily wasn't originally the plan but life happens.

 

That car is running on one rotor.

Under what circumstances did this begin?

It could be a number of reasons like a failed injector, or a wiring problem.

However seeing as this is a turbo NA of unknown origin, best to start with a basic compression test. Unfortunately I'd assume it has lost compression. Seeing as there is no "turbo kit" per say to convert an NA engine to turbo, who knows what was done? The car could be a ticking time bomb with the NA ECU. Already from the video it's obvious the AFM is in the incorrect orientation and there's some hacking that has taken place. Notice the hose to the BAC just left open sucking engine bay air with that white nipple. Narrowband O2 that looks stock, hinting at a stock ECU being used.

 

I wonder if the guy who installed that turbo did a poor attempt at Project Tina Stage 1.

 

Are you referring to the spark plug jammed into a hose? haha

Aaron is spot on, that's a 1 rotor engine you have running there.

Test compression before you check/test anything else.

What kind of driving were you doing on the highway before this happened? Any wide open throttle stuff?

 

Regular high way driving. Commute normally did have one section were I passed a semi and I hit WOT.

 

i wanna know about that gold intake, is the foil film or vinyl? i have the vinyl didn't think it would hold up to engine bay temps.. thats looks to be a foil, im sure you didnt install it and dont have a clue were he got it though...

 

We use the DEI foil tape on Subarus, and it had also been used on UIMs and LIMs on this site. Never heard of or seen this vinyl you use.

you never heard of a vinyl car wrap?

very stretchy.
im doing my rims, and maybe my hole FB.. and a jetski.

the gold i have matches the GTR more then the R8 in the flea bay ad

 

I've heard of vinyl car wrap, I've never heard of someone using it in an engine bay.

 

truth is i saw the foil and ordered the wrong, now im digging the vinyl, but for outside stuff, replacing paint. i have it in blue and red, here is my tool box.

got to learn to apply it before i throw it on some rims or a car. i figured my box is a good place to start.

sorry i can't add to the orginal topic until he comes back with the compression is fine, or the engine is toast, we all know it's toast soo..

 

A spark plug? Wow.

To the OP, another unfortunate thing is that damage from running lean/too much timing (detonation and/or preignition) can cause a delayed blown engine. The damage occurs but then the seal pieces stay in place (especially with those stupid 3 piece seals). The engine runs fine until a major RPM change or a shutdown and startup. Then the seal has fallen apart as it's no longer being pressed against the housing and held in place by gas pressure.

In that case though, damage to housings is usually minimal or non-existent.

Do you know anything about this car? Such as what EMS is being used? What fuel system modifications have taken place, etc.?

 

initial thought when i saw the video, blown engine, which is most likely the case.

turboing a non turbo car requires even more care than working on a non turbo car, as you cannot just start randomly throwing things at a non turbo and make it work. it is a high compression engine, less tolerant to detonation. its likely an original old tired 3 piece apex seal engine, again less tolerant to detonation. the stock ecu does not account for timing retard for boost.. i could go on for days of the improper way to turbo an n/a car but i won't.


the fact the car was running fine and then sounded like a pissed off lawnmower usually means one thing, the person who built it only knows how to turn a wrench.

it never ceases to amaze me that people still fall for this crap. especially with a conversion you need to know the answers to the questions before even asking them to a seller, i woulda had a field day talking to this guy when he was trying to pawn off that car and i hope you didn't pay more than about a grand for it, but i also have a feeling you paid 5 times that amount.
