new mortor build idea?
 

so i hear the new wrx sti are using the same port inject method as our fa20 engines... queston is would we be able to use the 2015 sti block with our fa20 head? sounds like a Frankenstein (k24vtec) build but if its possible il would def do it! i wanna get the most power i can from n/a.. plz comment thanks

Sorry, first thing I thought of when reading the title.

Same, :bellyroll:

How does the engine sharing the port fuel injection (which it doesn't) make any of the block parts compatible?

Last I saw the next STI will use the same engine as the current STI (EJ25) while the next WRX will have the FA20DIT which is a pure direction injection (not split port/direct injection like we have) engine.

That'd be a mortAr.

hahah my fault dam auto correct! lame excuse :bonk:

All in good fun.

Kidding aside, it will be interesting to see what kind of cross platforming we can do. Interested to see what fits and what is an "upgrade". I liked taking the LS7 manifold and putting it on my LS1 Camaro. Easy power gain.

didnt really look into it but makes sense/: it would be awesome thou. really hope something like that would happen in the future...

for the price of a 2015 sti motor, I'm sure a fully built short block from one of the vendors would come out way cheaper...

true but i want that 2.5l torque... i dont think I'm going to FI my fa20 anytime soon.. too scared lol

so you don't want FI, but want to swap a 2015 STi motor...you do know that STi's are turbo right? :bonk:

It will work
It will fit
It won't be plug and play
It is however a factory turbo setup on a fa20

2015 WRX STi is a EJ25, 2015 WRX (non-STi) is a FA20DIT.

I'd say by the time you'd bought the FA20DIT and modified it to fit, you'd probably have spent enough to rebuild and turbocharge your NA FA20 (and made more power and depending on the shop and parts, made it more reliable).

sure do.. i was looking just at the block.. im pretty sure sumone is bound to blow it at put it up for sell or somthing.. but since now i know it won't work all i can do is dream for a 200hp 170tq na engine<\3:cry:
