i have a 94 v6 and i want to go to a v8. what all will i need to do and what size of v8 will i be able to put in there? does anyone have any good websites or know what all i will need to change? im looking to make it a project and not just sell it and get a v8.

 

have you read any of the stickies on top of the pages ?

 

You will need a donner car. It would be easiest to start with a 93-97 LT1 350. LS1 350 is an option but it will add a lot of hours and research to the project. You should get a complete car. You will need almost everything off the drive line down to the fuel lines. If you purchased all these parts seprately it would cost you thousands even from a yard.

This car is not like a 86 monte carlo that just any engine will fit. Every bracket, every mount, every part of the wiring harness, your fuel system, your cooalnt system, AC system, transmition and emission are all designed for car/engine combination. Even going from a 3.4 V-6 to a 3.8 V-6 is a huge under taking.

The reason everyone tells you just buy a V-8 is because that project cost as much as what the V-8 are selling for. Also a restored/well maintained V-8 is going to be worth a lot more the a converted car. The only time I think this project is worth whiled is when you have a low mileage well maintain V-8 that was wrecked and you find a V-6 car with a blown motor that is in good condition and you can get it for next to nothing.

Let say your V-6 is worth $2500 you buy a wreched V-8 car with 80K for $1500 you then spend about 300 hours work to change everything over. If you replace all the normal wear items that will be another $1000 and another $300 for supplies, wires, nuts and bolts.
So now you have all told $5300 plus 300 hours worth of work. You would have a reliable car with 80,000 miles on it. This car is worth about $3000-$3500, Sorry the converted cars just do not sell well.

Or you sell your car for $2500 buy a V-8 car with with a blown head gasket for $2000 you pull the motor and rebuild it ($2000) plus all the wear items $1000 suppies 300. Total hours about 100. Your total investment $2800 and you now have a $5000 car with a fresh engine. Half the cost half the work and a car worth almost twice as much when done.The convertion makes no sense.

 

Someday when my V6 dies I want to drop an LS7 in mine... but yes I know how much time effort and $ that would be so that's why I said someday.

So if you wanted to do something like that it'd be worth it. But just to upgrade to an LT1 or LS1 yeah might as well just get a whole car.

 

you have a 4th gen yet you posted in the third gen section why?

 

Don't forget the need to swap the k-member for the mounts, as well as the front springs (to match the engine weight).

And personally, if I wanted to do a swap, I'd go for a LSX block instead of the LS7 (cheaper, bigger potential w/ tall-deck version).

 

maybe he forgot that 1992 was the last year of the third gens??? at least he wasn't completely off course, he has a sixxer and posted in V6 Tech (even if it's the wrong one )

 

i have a 91 rs v6 i dont know what to do with it should i just tune it the way it is???!?!?! some one help!

 

no u shouldent just "tune it" the way it is. you should go for 8 holes. so drop in a 350 chevy small block.
