I did a coil on plug conversion on my race car using just stock truck coils. They fire the methanol without issue even when it's rich enough to milk the oil
Pros: fire methanol without issue, handle rich conditions
Put an AC Delco alternator on my Celica because I couldn't get a Denso for it. Wasn't going to buy a store brand reman that'll die in 6 months.
Pros: better than store brand
Vehicle:
Toyota Celica
If it was me, I’d go with the ACDelco. Never had any issues with them so far. Checking for the best warranty is something else you might consider, just make sure to read that fine print closely.
Pros: no issues so far
RockAuto sells AC Delco oil filters for $9. AC/D dexos 5-quart for $19 and one single quart for $4.
Pros: affordable, easy to find
I buy 6 quarts of Pennzoil 5w30 full synthetic and an AC Delco filter for like $38 from Walmart.
Pros: affordable, easy to find
In my area I usually buy my Mobil One full synthetic at Walmart in the 5qt jug for roughly $22, use what I need (my vehicle uses litters ...) My Delco filter is like $6.
Pros: cheap, easy to find
I’ve had a pump put out low pressure and it was a brand new pump at that. Only get ac Delco pump or swap the pump itself out for a walbro or the new Holley in tank pump and sending unit for our trucks, the fuel pumps are the weak point in these trucks.
Pros: new pump, low pressure
Cons: fuel pumps weak point
Vehicle:
Chevrolet
When those AcDelco tie rod ends wear out in a few miles, the play will vibrate and destroy the rest of your new parts.
Cons: wear out quickly, destroy other parts
The issue you can run into is most common vehicle alternators are light duty at best. Lets say its a 100 amp alt, don't pull more than 40 amps continuous. A great example is the AC Delco 10si alternator. Loads of cheap knock offs and copies of that alternator all claiming crazy high amperage but none list the duty cycle. The 10si frame is designed for 40 amps of power and the heat that creates. You might be able to get a little more cooling with a better fan but you won't get 100+ amps out of one.
Cons: light duty, low continuous amperage, not for high power
