i'm considering buying one of corksport's used j-spec S5 engines for my 88 10AE because my engine lost compression on the rear rotor and i just dont have the cash to buy a new engine from atkins or mazdatrix etc.. corksport seems to be a reliable company and had suggested the S5 as an alternate because they had no S4 engines in. what, if anything would i need to do to make the S5 engine work properly? i'm assuming bolting on my intake, emissions junk, on engine fuel system parts, etc. are there any wiring changes that should be made or anything that might make this more trouble than its worth? are there any advantages or disadvantages with this?

 

as long as you have your t2 motor next to it... its pretty easy.... you have to swap out the front covers.. because the s5 has an electric omp whereas the s4 has a mechanical... and then just put the s4 manifolds on, and the s4 waterpump housing, and your good to go... id leave the s5 turbo on there though

 

thats what i was thinking. i believe its a more efficient turbo and from what i've read it resists cracking.

 

yeah, and while the motor is out, might as well port the wastegate!

 

couldnt u keep the s5 manifolds on there...isnt all u have to change is the front cover and omp and throttle body

 

I just ported my wastegate the other day, I must say, it's quite large now.

 

i'm not too sure, thats why i was asking so if i do decide to order an s5 engine i dont botch it up assuming what will work with what.

 

go to rotaryresurection.com and go on the tech section...from there ull know wat to do

 

cool, i'll look that up after work tonight!
