im doing an s5 T2 swap into an s4 N/a chassis... i was wondering who else has done it because i called a local rotary shop and they told me its impossible... so the swap has already begun, and now im stuck because it wont hold an idle... if youve done one locally, could u come and take a look or refer me to someone who can help? im in anaheim, ca btw...

 

nope. Not a single one of us has done a swap.

Normally, I'd give you all kinds of crap about not searching, but I have a couple of friends that are in the business of working on rotaries. You can check out Yoshiya's shop (do a search for Yoshi), or you can check out Dave's shop (do a search for GuitarJunkie). Or... you can just do a search for Rotary Mechanic like everyone else does. Did you really think that nobody has asked about this before?

 

Wow, here is little help for you since the post above wasn't to enough the swap is possible. Check all your vacumes check all hoses, check the exhaust mani for leaks check the intake mani for leaks. Check the map check the tps, check the timing make sure it's right. Sounds like a boost leak some where. Check for where all the gaskets that go on the intake and exhuast mani and around the intake. Thats the best that i could do for you. And if you could find the problem b4 you take it to a shop you could save yourself a bundle on repairs and looking for a leak.

 

Wich rotary shop told you that? i think everybody should boycot(sp?) them

 

which harness are u using....s5 or the s4t2 one...if u use the s4t2 harness you would need to change the front cover to a s4t2 one and the throttle body along with the s4t2 injectors..

 

lol i have done a search and didnt find what i needed so i posted this thread...well yahz it was spose to go to dave's shop, but dave passed away.... RIP, and the guys there took the car and told me they cant do it so they brought the car back and charged me towing, and now the car is at yoshiya's shop, neptunespeed, and they gaurentee it to work after couple of weeks so the cars sitting in their garage... thanks for the helpz though...


it was actually dave's shop lucky 7, or not dave's shop but the one he's affiliated to... they said that if they did it the engine would detonate and that they could trade all my s5 stuff for their s4 stuff to make it work... i said no thanks and they brought the car back to me a week after they had it and told me they could get it to work.... now they say that they cant, so oh wellz, i lost money on the tow... lol

 

I'm pretty sure you misunderstood. Dave definitely knew his junk. Either way, you'll be happy with Yoshiya. He'll treat you right. Good luck and let us know how things turn out.

 

anything is possible!
you just gotta PAY TO PLAY.

 

adee-do

 

well, got my car back from yoshi, everything was fine, told me i had a dripping injector so wen i did that i decided to take my emissions out since im there, and i readjusted my idle, but now sometimes wen im driving and i clutch idles at 1100 if i put in gear and pull it back out, it idles at 775... and sometimes the idle is jumpy... like today i let it warm up and it was jumping up and down about 1100-1750... dunno wats up... hit the gas a couple of times put in gear and pulled it out then the idle steadied... any ideas?
