So here its my Q can you do this kind of swap i think on this cuz i cant find a 13b engine so can you fit it with no problem in a s4 ?

 

no, the mounts are different

 

Anything is possible, but it is more feasible to have good used engine parts shipped to you for a rebuild.

 

it all depends if you already have the 12a and plan to make the mounts yourself, and all the custom work yourself. if not cost will be the same to slowly piece up a 13b. or rebuild what you already have.

 

yes, it can fit

 

More trouble than it's worth plus you will have less power.

 

it's not a simple bolt in. ultimately, i don't think it would be worth your effort. you're better off just waiting and finding someone/somewhere to import a rebuilt 13B if you have no interest in building one yourself.

 

Thanks for all the answers ! I apreciate that! Well here in my country its a pain in the a** to find or import a motor so i find this fb the hole car and theres no problem to fit them to my logic cuz already has a toyota 18r inside!
