I wanna do the lower mounts, O2 sensor, and plugs/wires/etc, focusing on getting things I can afford right now, prioritizing things I can't do later. I figure lower mounts, and O2 are a pain otherwise, but I want a list of things I should replace/check once I get it going, so that by summer time she'll be very well on her way to being a great car

-O2
-motor and tranny mounts
-plugs/wires
-fuel filter
-Tranny filter and such for new tranny


add to my list  :icon_biggrin:

O2 sensor is cake on a TGP. on the top of the turbo.

I would do all four subframe mounts. Runs about $200 from GM dealer. Well worth it!

think about flushing the heater core, inspecting the steering rack/lines for leaks, possibly changing the o-rings on the evap core?

These are all things that I wish I hadn't had the absence of mind to look over when I did this!! :icon_lol:

Might change the crank sensor if it hasn't been done?

It doesn't run anymore.

I agree on the sub frame bushings. They should be toast by now. I would also check that mostly steel heater hose that runs along the passenger side of the engine bay. Its not really hard to do with the engine in but is very easy when the engine is out. Ask Jimmy I asked him if we should do it and we didn't then the day we were putting the engine in it sprung a leak in it. rusted from the inside out.

Main thing keeping it from running when I first got it!  :icon_mrgreen:

Curious, why do you say the O2 was such a pain to change? We only have one and it's mounted on top of the turbo, unless you either moved it to another location or thought there were two?

I was just going on the assumption that it was in a similar place compared to the Cutty. Apparently it's not, so that's better, since that one's a pain!  :laugh:

Nice! Yeah we got lucky I guess lol. So just how much work is it exactly to remove the old trans, and install a 5spd? Roughly a week? Less?

I dunno, but I hope to find out someday  :icon_mrgreen: If things go as planned, Ken will come up friday and we'll start tearing it down, and hopefully saturday get the new tranny in and have it mostly buttoned up saturday night

I would also do steering rack and PS lines.  If you have to spare change to do it I suggest. Kind of a pain in the ass with a motor in there.

psych0matt, can you please document your swap? I have two people, one of which is my girlfriend, pushing me to do a 5 speed swap, and I am learning to drive manual now so, I'll probably end up going that route, and I'd like a tutorial on it...preferably with pics if you can  :icon_mrgreen: Atleast pics on where to cut for the clutch pedal, where to weld the turbo mounting bracket, and anything else that will be a pain.

Also, who is doing your chip? You will need it re-burned for the 5 speed, correct?

   Now I'm running mine without the 5 speed burn for now, But yea, it would be a good Idea to do it while your swapping.

   It took me roughly around 25 minutes to cut a square hole, out of a round hole, so that the master slave will fit. just keep 

   cutting and fitting until  its a perfect fit.And as far as your turbo bracket, let me see if I can get the guy who welded mine up,

   just simply copycat it.

psych0matt

So, I don't know where the assumption was made that I was swapping in a 5 speed, but I'm just putting in another auto :dunno:

I have all the 5 speed swap parts (minus the tranny itself) lined up, but I won't be trying to tackle that for a long while, when I have lots of time to mess with it. I'm moving back to michigan in may, so for now I just want it up and running correctly

Sorry man, I must be mixing up threads, I thought you were throwing a 5 speed in. My bad.

Jimmy, who burnt your chip? Also, I'd really appreciate if you could get ahold of the guy who made your bracket. Are you running a 282 or 284? Any differences really?
