Northstar? if it needed rebuilding it wouldn't be worth it IMO. parts are extreamly expensive for thes things and you just can't do a ring and valve job on them like you could a sbc for example. the pair of hd gaskets will run you about 150.oo . the rod bolts and bearings MUST be changed if you pull the pistons for example. but if it "runs good" you may not have to open it up. if it had reasonable care 190K isn't as bad as it sounds. the N* has very hard cyl walls and wear very little. go listen to it before you make a decission.
what ECM were you planning on using? that may be a factor also as the early TB would need to be changed for some setups to work in the Fiero.
4 speed is not easy with the N* either. I did an Izusu with mine and although it can be done (I did) it ain't easy. lots of fabrication to move the throwout fork arm and relocation of the shift cables.
Its a 4.9.
Devilles kept the 4.9 through 95. 191k is pretty normal to find on a used one. IMO just find the motor/trans, wiring and harness. You really don't need the whole car and could spend quite a bit less on just what you need unless you have the time to part it out and make your money back. I paid $203 for my 93 deville motor, harness, and ECM with 150k on the clock. All you need is the motor, ECM and connectors, and engine harness.
You wont get very good gas mileage with the 4 speed but it will hold the power and run like a champ. I was originally planing to use this tranny but the 88 cradle swap changed all of that for me.
I can't give you a very close estimate on the cost of a rebuild cause I got mine at cost from a friend in the business. I can give you all the part numbers if you are interested. For me, at cost, it came to $355 for gaskets, rings, and bearings for the good stuff (Victor reins, engine tech chrome molly, ect). And 180 for a new cam cause the stock one was no good. The sleeves need to be checked out very well if you are going rebuild. They are probably fine if its running and NOT smoking. If its running I would just put it in and worry about a rebuild later once its in the fiero and running.
Rebuild parts can be ordered online at rockauto.com. Be sure to use the discount code if going this route as it will save you a ton on money.
Head gasket kit (includes all gaskets needed to change everything from heads up) ~117
Re-ring kit (best rings, incl main and rod bearings, and gaskets) ~475
Master rebuild kit (includes all gaskets, seals, bearings, rings and pistons... probably way more then you'll need) ~12-1500
One word of advise... Use the best rings you can. They make a huge difference in the longevity of the rebuild. Good luck in what ever you decide to do.
