I have been searching everywhere to find any info on installing the PPE headers on the 3IS without luck. I am able to find it for the 2IS, but not the 3IS.

I am fairly mechanical, but use to working on 2JZ's, which tend to have much more space in the engine bay. I am positive I can swap out headers myself in general, but was looking for any guides or info, so I can make sure that with this being my DD, I can estimate down time for the car, and make sure I am able to do it with my current tools and in my tiny garage. Also, although I am not scared to wrench on any old car, this is the nicest car I have ever owned, so I am a bit intimidated without any info on this.

Anyone got any tips, any pointers? What am I looking at getting myself in to? I do not have a car lift.

 

Apparently the RWD install is not so bad, while the AWD ones are a all day thing to install. There are some videos on YT about installing on a 250 and a RC, should give you a idea of what it would be like. You could also give RR racing a call. They are very friendly & helpful, they also have there owned RR racing tuned PPE headers for our cars.

 

Thanks, I actually gave RR racing a call before making this post, and they told me you had to drop the subframe, leading me to ask here lol. There has to be a way around doing that.

 

The only way is the drop the subframe lol

 

I'm personally interested in the headers, so I asked my friend who has worked as a race team/performance shop mechanic for the last ~30 years. He immediately said "headers on a V6 are usually a big job".

 

What about on a 4 cylinder turbo?

 

A Turbo engine dose not have headers, it has a Downpipe. And no clue about the 2L Turbo unfortunately for how bad the downpipe install is.
