Hi guys, I just got my 1993 Civic B16a2 turbo back from a full engine rebuild after I blew it up.

Its running T3/T04e turbo
Tial 38mm wastegate
450cc DSM injectos (thanks HMT for the guide)
Hondata (very rough basemap)
Stock fuel pump + inline fuel pump
Forged Pistons abd rods 9.0:1 comp

It seemed a little rough but I hoped it would make it to the dyno. I drove for 3 miles then parked it on my drive, came out after a couple of hours and when it started it sounded like a subaru Impreza! I checked the injectors, changed the plugs and leads, still the same.

I thought it was maybe too much fuel pressure so I took the inline fuel pump out and tried it without it.

Now it still runs really rough and cut out after about 1 minute. It doesnt start 1st time either, needs several turns to get it going. Idle is very low too.

Also I should add the speedo was all over the place when it was driving ok, kept dropping down lower than the speed i was actually doing.

Anyone got any ideas?

Thanks

Nick

 

sounds to me your timing might be off, did you rebuild it yourself? when I did my rebuild my first startup was rough and it sounded like almost bubbly, I check everything on the topend and made sure the crank and camgears were lined up at TDC, I found out I was off by three teeth, took off timing belt and reinstalled correctly, also I adjusted the valves and it now runs fine.

 

make shure it is firing on all cylinders.

 

if it sounds like a subaru impreza you better make sure everything was rebuilt correctly...

 

If i disconnect each injector it almost dies so it seems to running on all 4.

My dad is a mechanic and will be back from his hols tomorrow, think I will let him have a look.

 

I guess the difference is my Wife's new Impreza RS actually runs?

 

make sure youre engine/tranny/chassis ground wires are good

 

at first I thought u were having nightmare problems, as in you have trouble sleeping where you close your eyes and the sandman comes to get you or some ----..

yeah I'm going to second the ground solution.
