Hi I like to install a 20b in my 73 Rx3.I know what the cost is for a engine but I don't know what I need to install it like what oil pan I use or do I have to fab up one.What the best spot to install the motor mount on the front,middle or on the back plate.

See I am going full custom on my Rx3 I like to install a 20b over a 13B turbo.I am install a ford 8.8 rear end and convert over to 5 lugs.I like to install all the part with out cutting up my car.My car is mint with 59,000 mile but I like to be the only one in my area with a 20b Rx3.Can someone give a number on what HP will I get with a 20B stock, street port ,bridgeport,with or with out a turbo over a 13B the same way.

Thanks Carlos

 

That will cost you around 20K for a setup like that(turbo)Maybe a little cheaper if you go NAI

I did one for a customer before and you need a lot of custom fab work into what you want to do it right,custom oil pan,Turbo header,intercooler,Radiator..........The Rx3 i did i didn't cut the firewall or anything and the job was done with lots of work to preseve the Rx3 body.I have done many 20B engine swaps and it take a lot of skill and money,believe me.

The one i did made 600hp daily driver and he had lots of fun with it till he sold it to another country.If you really like the car then you need to spend lots of money to make it right.
