Turbo question

Love the ZZP **** talkers on this site. Especially when you have ABSOLUTELY no experience. 115+ traps on my ZZP mail order turbo tune for well over a year.
 


If you only want 6 pounds why go turbo? Theres a guy selling the ZZP SSM90 kit. I had one that I pieced together and had no problem going 13.0 on a 3.4 pulley.
 
So a top swap would be better? I just have a great deal on a turbo but not the whole kit so if I could piece a kit together cheaper than everything for a top swap I figured I would go this route. I thought turbos were better? I've hear because u can get a lot more power out of it if u mod more which I will further down the road and also because the turbo doesn't run all the time like the supercharger which is always running on the belt. I'm just looking for more powed because I love this car and plan on keeping it for a very long time and I want to be able to beat those other cars on the road also.
 
With a turbo kit, you will probably get more MPG, and run MUCH faster per dollar than a top swap.

Top swap requires about as much labor as a turbo install goes (assuming you can throw a 2.5inch downpipe together quickly or buy one). I have turbo'd many cars for less than $800 in parts, including extras like tuning / wideband / gauges. A few locals have been able to replicate this as well.

As far as running a turbo un-intercooled... I would do that well before running a supercharger un-intercooled, lol. You can get your turbo in whatever size you wish, you should shoot for around 45lbs of net flow potential. A GM4 turbo was commonly sold by zzp for what you are trying to do, as they were a stock truck turbo that could be had for about $100 for some time. They sold a few kits for that turbo, for around $800 in bolt on format, so as you could imagine you could toss something together easily enough if you were diligent about it.

Yes. If they are not looking for a lot of power or incredibly low boost with a turbo then there's no reason to even consider doing a turbo swap.

Honestly, If I get another DD, I am probably going to put a crap turbo setup on one of my GTP's just for the fun factor of having a turbo over a supercharger. After I put a cam, exhaust, smaller pulley on any of my GTP's I would probably only be a few bucks away from putting a turbo on it.... My advantage now is that I have a few turbos, intercoolers, hot pipes laying around to make the process fairly simple.
 
So would I have to buy a new DP or modify mine if I have a new one from zzp? It's a 2.5" with the ubend delete.

There is really no such thing as a "turbo back"... Stock "cat back" exhaust is fine for a turbo setup... the downpipe is still called the downpipe in a "turbo back" exhaust.

The 2.5 zzp downpipe you have right now would be a good start, but you need to plumb up and over the trans between the brake booster and the crossover to get to the turbo. Its a few complicated bends and will require some creativity and some way to weld it together.... (I have had customers tape together downpipes and bring them over to get welded).

zzp sells many types of downpipes premade and ready to go as well as the turbo crossovers.
 
Ok, but I've seen like the STS turbo kits where the turbo is actually in the back of the exhaust. That's what I was wondering about. They only have pre made kits for newer cars on their web site.

How do you hook up an intercooler with the supercharger? Would it be a bad idea to to put the intercooler on before i throw on a supercharger?

That's what I did with my dd. ;) don't be a pu$$y. There should never be a doubt in your mind. :)



The problem with the STS kit is the long lines that run with it. The turbo is oil cooled(unless you go ball bearing then its water cooled) the oil return line is gravity fed so keep that in mind. An intercooler for the m90 is more or less an "aftercooler." In that it sits under the s/c cooling the air after it's sucked in. And yes an intercooler is always a good idea before dropping pullies on the extreme end of the spectrum.
 
put the intercooler on before the sc? if im readin this right and it wasent a typo ill go ahead and be the asshat and address the elephant in the room. these are all good questions to ask so dont get me wrong, but most of them are questions an 8th grader in shop would ask. you dont know what your gettin yourself into. perhaps do a little research on how an na engine, turbo engine and a sc engine work before you worry about building either. again this is a good place to get knowledge but your on page one, and before you even start buying parts you need to read the whole book twice. im not saying this isnt something you can do. but ill tell ya right now its gonna be a while before you have the knowledge and ability to do so. do some reading and some learning. then decide what to do.
