The car dosen't really bog, rather time on the track 'bogs' from 8.9 seconds in the 1/8 mile to 8.7 seconds. This thing pulls hard right up to fuel cut (limiter).

No big deal - I'll play around with the fluid level in the tranny to get it to shift before limiter... Part of my problem is that I am ...

I was reading up on trying to raise the stock rev limit in my '91 Legacy T with TD05, WRX IC and FMU. I keep bouncing off the limiter between 1st and 2nd gear shifts (auto tranny) and it really bogs me down. How could I clamp things off as mentioned below? I have lots of fuel control with the FMU ...

Ok then... I guess I'll look for the answer in some other thread's. Just wanted to know the wire that sends the signal. I guess it's the red one with the stripe??

VRG3: Do you follow what I am trying to do? What wire do I want to tap into with resistance to modify the reported amount of air?

Thanks!

Which wire is this? I am very interested! I thought that if the MAF reported less air flow that the ECU would maintain advanced timing longer and I would make up for the fueling with my 5th injector.

Where is the timing case?

Thanks!

I am running a '91 T with a 60 trim T3, WRX TMIC with water spray, 550cc 5th injector above 13psi (injector flow and trigger psi adjustable), Wlabro FP, 4.10 gears with rear lsd, 195/45/15 wheels (for the gearing), Auto tranny with cooler.

Aha! I should have looked a little closer! Great job. This is why I usually shutup - my 2 censt are usually in some other thread...

Great Turbo. I've been running one on my Legacy for 4 months. The 90 deg bend fits fine and you can use your stock plumbing to lead up to it without any problems!

The tight part is the compressor outlet. I modified my PCV plumbing (not a big deal) and found the perfect radiator hose from Advance ...

Problem solved :) The fluid level was still too low tonight and I added a whole lot to it! I was not reading the stick properly or something and thought I had enough in there yesterday and on previous checks. Now the car shifts properly or right at 6500 with no cut out. Tomorrow I'll do some Gtech ...

I didn't know there was a rev limiter on these cars. Makes good sense that my problem is because of it! I have modded 2 other Legacy T's with auto trannies and never had a problem with the limiter. In fact, by varying the amount of fluid, we could get the tranny to shift at 7500 rpm (removed fluid ...

Thanks for sticking with me! Yes - only at full boost on the 1st to 2nd shift. The only difference I can see with this shift is the rpms are around 6600 which is a little higher than the others at 6100.

The O2 sensor is already disconnected from the ecu and system has reset. Any other ideas? tried a few more 1/4 mile runs last night but my times sure suffer with this cutout from first to second. I did notice on the graphs from my runs that the 1st to second shifts around 6600 rpm and the next shift ...

Thanks VRG3,

My plugs are gapped about at about for higher boost about 30 but I'll check them out. One thing to note: My O2 sensor is not working in its current position - just before the second cat. Maybe this has something to do with it.

Changed my coil pack last night and it didn't take the ...

Hello,

I am tuning a '91 Legacy T with auto tranny and am experiencing what I think is ignition cut out when the car shifts from 1st to 2nd on a hard run. I don't think that it is fuel cut because I dump a cloud of unburnt (black) fuel during the cut out time. NOTE: This cut out time is .5 seconds ...

Hey Guys,

These turbos are great bolt on's for our engines!

I finally had a little time tonight to troubleshoot ... I have narrowed down the problem a little more. I always have 12 volts at SBF 1 & 2 and at both sides of the fuseable link. There is always 12 volts at the starter. If I unplug the 3 wire connector (Blue, Black Yellow and Black Red) from the ...

I have a little update and a question...

I have 12 volts into my main fuse box (under hood) but now I only have 2 volts at SBF 4 and on the corrsponding bvlack and yellow stipped ignition wire. My battery dosen't drain - been at 12 volts for a month in this car. Where is the voltage going? (Key is ...

Thanks for the confirmation Josh!

I have spent a while testing wires under the dash and especially those feeding the ignition in the column. Do you think the alternator will only give ~2volts if the constant power wire to the ignition is cut?

I'll give it another go over and I hope that is the problem.

Thanks,

Matt

I did a bit more troubleshooting. The temp outside was warm at -10 deg C (but the wind is what got me today) so I had to spend an hour or so on this mess.

The positive battery cable is OK and I traced the large white cables from the alternator (the ones with low voltage - around 2 volts not 6.5 ...

Can I replace my stock 2.2 T injectors with RS 550 cc Top Feeds?

I guess you are right. When I measure battery voltage at the battery the is 12 volts and I get 12 volts at other places mentioned in the first post but this alternator thing is definately strange.

I'll find a new battery.

Matt

Hey vrg3,

I checked SBF 4 and the fuseable link - all seems to have power and continuity. One thing I did notice, my alternator only has 6.5 volts of power.

Any ideas?

Thanks,

Matt
