I am in the process of a TII swap into an FB. I bought a J-spec S4 engine for the swap, well so I thought.

I am a mostly an FB guy, so I am kinda a newb to the turbo world.

I have S5 rotor housings, S5 turbo and manifold, but I dont have an electric OMP. I am almost certain that I have the square brown low imp Injectors also, but I need to remove a few more things to get to them to make 110% sure.






So my guess that my motor is a mix match of parts, What I need to know, is what harness to use for my swap. I would like to run an S4 so I can use the Rtek modded ECU that I already have.

this is an s5 engine and turbo i think i has an s4 front cover on it

 

dude that engine is rusted to ****.

 

I know, but it blows a 100psi in both rotors! Didnt you learn not to judge a book by the cover lol

 

sand blast time

 

You gonna do it for me? I used to live in lousiana, in the Lake charles area.

 

looks like an S4 block with an S5 turbo to me...

 

looks like a 4 block with an S5 Turbo to me... lol

b/c thats def. a s5 turbo
and thats def. a manual front cover..

 

But what about the sensor position, I thought that ment it was an s5 rotor housing.

But my question still hasnt been answered, I already have a N333 ECU with an Rtek 1.7 in it. So in theory I should be able to use a 86-87 harness and low imp injectors and be fine right?

^^^^
Non useless post lol

 

Front rotor housing appears to be S5, rear appears to be an FD.

 

Are you kidding me? How can you tell? This is one hodge podge engine I swear!

 

Bottom of the housings on the spark plug side.

 

Well I guess my car will have a lil piece of every generation in it! lol

Since I have a Mech Omp, and low imp injectors.

 

You first gen guys crack me up

Coming into the 2nd gen forum expecting answers! Bah!

We will run circles around your question until post #117. Ted will then get annoyed and help you.

(j\k :P )

^^ Useless post

 

I know, my FC buddys warned me about this! lol

We over in the FB section, get to the point and are pretty flame free, but the rumor in the FB section is that with the FC & FD guys you need a flame suit to post in those sections, and they like to post 5 pages on a "how do I do a burn out" thread and the ones with good questions go unanswered, but thats just rumor lol.

 

Yes, you can use S4 ECU, harness and low imp injectors on your S5 engine.
I know becuse I'm doing it myself.

 

if you've got s4 sensors and all that stuff you should be fine, especially with a mechanical OMP

 

The sensors are what determines what computer you can use. More than what the actual internals of the engine are. I have a S5 with FD rotors, and an S4 front cover with Mech OMP.

OH and the FD rotor housings have the spark plugs closer together than the FC. I know you can run one or the other, but I've never heard of combining the two.

 

Ok cool thanks guys!

 

How do you use an S5 and a FD housing! something there just doesnt make since!

Where is KevinLanders, or RETed, or Icemark, and the others!

 

You guys are great help finally! I bought an engine that I also thought was an S4 T2 but then like 2 months later Im checking the engne and its an S5 because of the eletronic OMP. I was pissed because i wanted to mod it,get bnr turbo upgrade, and rtek but i cant with an S5. But since one of you said as long as i have the right eletrical stuff and a mechanical OMP then I guess I will be fine! Sorry about jacking the thread I just wanted to make sure this will be ok.

 

Well im glad some one got an answer

 

I have a J-Spec TII engine also. It has the knock-hole sensor threads on the sides of the housing, no sensor in either threaded hole, but it has a mechanical OMP also. I had the idea that it was a S5 engine, but I was told that it is a S4 engine. I am using a S4 N/A harness and an N332 ECU.

 

lol I guess they don't answer newbs with an over asked question bump for a metrosexual........haha j/k
