I'm looking for a vacuum hose diagram for my '89 TII online. Does anyone know where I can find one? If not, maybe an answer to this question. Is there a hose that is teed off of the hose going between the wastegate actuator and the turbo? I think it's supposed to go to a solenoid or something near the oil filler neck? I was looking through a manual in some guys garage and noticed this. My setup right now has a hose going between the wastegate actuator and turbo, with nothing teed off of that. I'm also having boost problems and was wondering if this was the culprit? I hope that question made sense. Thanks.

 

that means your stock boost controller is disabled and you will only be running 5psi instead of 8.
personaly I'd just forgot about the stock boost controller buy an aftermaket one, either manual (cheap) or electric. ($$$). just be carefull and don't go over 10psi or so.

 

Ok, so the hose teed off of that line just goes to the stock boost controller? Just running a hose from the actuator to the turbo limits your boost to 5 psi. then? Thanks for the response.

 

yes, the stock boost controller is a little box by the oil filler, which is where that line goes that you saw. by bypassing it and running straight from the turbo to wastegate, you'll only run 5psi. but with your exhaust you are probably running more from boost creep.

 

Yeah, I'm running up to 10 psi the way it is now. The car just ***** on me when I get in boost though. It's ok if I only let it go up to 3 or so psi., any more than that and it gets laggy. I was hoping the above was my problem, but I guess not

 

are you hitting fuel cut? or do you have an FCD? the ecu will cut out fuel at 8 or 9 psi and it'll feel like you hit a wall. to run over 9psi you need an FCD or an ecu upgrade.

 

I have an ecu upgrade so it's not fuel cut. Here's the scenario, cruising around 3k, punch it, starts to get going, I can hear the turbo spinning, hit 8-10 psi of boost, and then it won't accelarate. Not fast anyways. Basically the turbo doesn't seem to be helping. I have a new TID, vacuum hoses are good, holds 16-17 at idle, tps is in check. Any suggestions on what to look at next?

 

what ecu is it? the S-AFC listed in your sig won't get rid of fuel cut if thats what you are talking about, but I doubt you are hitting fuel cut if you are still moving, just not very fast. are you getting spark from all 4 wires? if one of the coils was dead it would still run, just not accell to well. when was the last time you changed your fuel filter, spark plugs and wires?

also check to see if you have any codes

The ecu has been reprogrammed by EL Prototypes. It was done through Corksport. I've changed fuel filter, plugs and wires. I guess I could check to see if I'm getting spark at all 4 wires. Thanks for helping me out.
