ok so i've found an '85 t/a with a 305 tpi and i bought the whole system for $275 which is a really good deal i think and i get everything the wiring and computer and whatever i need for it but i'm not sure hot to do all of this i have to pull the system myself i have a list of the stuff i need to pull from one of the tech articles on tpi but how difficult is it, will it take me a long time to pull it? and should i take the heads too if i'm putting the system on a tbi 305?
i need advice soon because i'm going to pull it saturday

 

Make sure you get the heads if your looking to make a performance build. Dont cut any wires and just take your time. If you find a sensor where it doesn't go, then just search on here and im sure someone can help.

Welcome to tpi.

 

That's a pretty good price.

Yeah, number one is don't cut any wires.

Part of the harness runs inside the car on the passenger side fender. That'll be the hardest part of removing the harness.

There's a bulkhead connector right there; you'll have to remove the pass. fender to get it out (believe me, it's easier to just remove the fender than to fight that cramped space).

On the other side of that bulkhead connector is only the computer connectors (two) and the (I think it's call the IP connector) which basically has the injector power wires and some other leads (it's a clear connector).

The intake is a snap to remove. Just be extra careful with the plastic vac. lines; they break easily.

Hit all the intake bolts and ESPECIALLY the thermostat housing bolts with PB Blaster (the best penetrating oil money can buy) so you don't break the heads (the thermo housing bolts are notorious for that). Let them soak for a day if possible, then hit them again right before you start on them.

Use actual Torx bits, not allen wrenches that sort of fit.

Get the distributor also. You might want the throttle cable, too since it's likely a different length.

Plan on a weekend (especially if beer is in the equation).

 

you think i should pull the fender off?
i dunno about that it's sittin in a junkyard and i don't know if they woul dappreciate me pulling parts that i'm not buying but i'll see
i've got some pics that i took of the car and some others on the lot
just click the pics and they'll show full size

 

my 87 ta had vents in the fenders, and I just remover the vent and had plenty of room to get the wires out, just be pacient and mark all the conectors so you know where they go

ok so i'm still in the process of pulling the tpi off of the 86 t/a but in my haste to pay for the system i forgot to make sure the ecm was there and it turns out that it isn't
any ideas where i can find a new ecm
i know i can look on ebay but are there any better places?

 

Is it an 85 or 86?? If it's an 85, it's probably a blessing the ECM is missing. The 85 ECMs were slow and not very well supported. Hit the junk yards. Look for an 86-90 (MAF type) ecm.

 

it's an 86 and it's going into an 89 in place of a tbi system

 

86-89 TPI ECM 1227165
