Is there a way to identify the lower intake manifold in between S4's and S5's. I got my S4 upper cam in either this morning or last night. Yay me but it wont line up with the lower. I have pics of it (lower) can some one help cause this is pissin me off now...
outer

inner

 

that's an S5 part.

 

Thanks K-Tune I needed that the guy that sold it to me told me it was S4...

 

NOW quick question on this can I use this even though I have a S4 upper intake. I know I'll have to modify it a little but thats what I'm doin to my car anyway.

 

it can be done...yes...but you may be better off just sourcing an S5 upper.

 

isn't S5 better for power?

 

I just got the rest of my stuff today so I'll end up with 2 UIM then it meen tryin to sell it and shipping.

 

S5 upper is cheaper than S4 lower. And adapter plates aren't cheap.

 

S5 LIM has larger ports that are meant to mate with the larger s5 T2 irons. You can see the differences if you compare the two LIM gaskets. The s5 UIM also has longer runners compared to the s4.

 

Now will the S4 Throttle body and electronics all go on the S5 with no problem right?

 

If you plan on keeping the OMP, you have to switch to the S4 front cover. Otherwise, you can premix.

 

where the hell did this answer come from?

 

LOL Ok now im gettin confused I starting to premix now. I'm Turboing my 6port so thats where my questions and gettin all these random parts I need. So I dont have to get the front cover then I can just get a block off plate and not worry about that part of the swap, Coo!!! NOW let me try this again!!! WILL A S4 TB FIT WITH ALL ELECTRONICS SENSORS TPS FIT ON A S5 UIM???

 

i think it should fit.

 

Thank you K-Tune for the answer. Sorry ya'll if I came off like a ******* but this car got me drove to the point of insanity and its not that far of anymore.

 

Rx-7's do that to ya

 

Welcome to the ballgame kid.

 

Yeah I had her for a year and 3 months been on the forums and searcheded and searched and some times cant find the answers so I have to ask and when the answer doesnt come as yes or no or this is how you do it. I get like I'm on a rag or some thing!!! lol No offense to any ladys if your reading this...

 

Will a complete s4 turbo TB assembly bolt up to an s5 turbo UIM? Yes. That's my setup right now actually. You will have to back off one of the studs some to get the nut on there. And the JDM S5 UIM's have a different bracket for the throttle cable. You may need to do some rigging to make a JDM manifold work. I know the N/A throttle cable is different from the turbo but I'm not sure how that changes the situation. I had to grind down part of the cruise control cable (I wanted to keep cruise), grind out parts of the bracket for the throttle cable, and adjust the nuts carefully.



In that pic I have an modified s4 TB bolted up to an s5 UIM. s4 TPS and OMP are installed, as well as coolant hoses.

Also note that the S5 UIM uses a longer center bolt than the s4. You'll have to get it from the dealer. I think the s4 is something like 115mm long and the s5 is 135mm.

 

Thanks for the info arghx for that info I will keep that in mind, this car is trippin me out I've spent more on it unemplyed than when I was working and I'm constantly gettin something for her cause she's startin to act stupid on me lately with the Aux. Ports both crapped out on me after I took off my header (Wired open or zip tied lol) they dont wanna any more and I feel the power loss. So I'm goin N/A turbo.

 

I built my motor when I was unemployed

 

lol and nice engine bay you have there Sir... I'm goin to go with a V-Mount set up I just need the intercooler & piping, Injectors, Oil pan and some hoses, electric fan and few other things I could have her done by X-mas but I wasn compression test her first so by easter is when I'm aiming to have it done...
