i am new to these cars so what is the differnce between the s4 and s5 and how can u tell i need to go to the scrap yard and get some interior parts and i hear the s5 has better parts so how do i know if anyone can help that would be great thanks

 

the "s" stands for "series. a s4 (series 4) was made from 1986 to 1988. a s5 (series 5) was made from 1989 to 1992.

 

Bingo! Also if you can't tell what year it is generally, and I say generally because it is interchangeable between series, the outer trim on an s4 has a square groove running along the middle and the s5 has a small groove along the bottom edge of the trim.

 

well that answer my question thanks alot

 

no problem, glad to help

 

Where you at in Indiana?

OT: S4 has black trim and tail lights like your avatar. It also has manual seat belts.

 

^ completely forgot about the seatbelts that would have been much quicker lol

 

Seatbelts and color matched trim are the easiest distinguishers

 

there are so many things that set the s4 and s5 apart...some people do S5 conversions on their S4 but the easiest and fastest way to tell (even if its a conversion) the S4 RPM goes to 8000 the S5 goes up to 9000

of course the front bumpers are diff. the mirrors are diff. taillights, side mouldings, but most importantly....the S5 have longer gears and a bit more power

 

Non-turbos: s4 goes to 7000rpm, s5 NA goes to 8000 for manual, 7500 for auto. I'm sure thats what Eddie meant.

 

haha yeah thats it...

 

nono s4 na goes to 8k

 

wait yeah I was right....

technically you're both right except one of you is talking about the redline and the other that actual end of the tach

 

I'm going off bouncing off the limiter hahaha

 

Sorry don't mean to high Jack this post but I'm looking at turbo 2 swap for my vert, but how can you tell differance between s4 and s5 turbo 2 motor?

 

Haha yeah we were talking about two different things, sorry dudes.

 

88rota the info your looking for should be in the faq thread but a few of the main differences you can see are the coolant fill cap on the water pump neck on the s4 the s5 has it on the radiator instead of the engine. Also the s4 omp is mechanical so it would have a cable going to it in stead of wire like on the s5

 

You mean rod instead of cable, and the s4 rad goes out easy, so don't use the rad as a end all check cause I have an s5 metal rad in my s4
