My observations and opinions of current street/strip turbo LS trends.

This thread is good and all and I agree 100% BUT the only issue I have with it is people still are not giving out proven combos that work. Speed Inc has and tuned some of the baddest turbo lsx cars around so they know a thing or 10 but why don't you give some of us some combos?

Or some people just don't have the funds to buy a 1800 dollar turbo sometimes. .. Just saying
Does this have to do with the low budget turbos like On3 that people buy and the all "American" guys get pist for buying something not made here in the USA... I know kinda random lol but I think that's dumb when someone gets pist of **** like that.

^ you are missing the point. If you can't afford to turbo your car then don't. It's expensive with cheap parts or quality parts. The OP mentioned it being silly to say "i'm on a budget so I got this half *** turbo because my pockets are full of lint but what's the best cam shaft money can buy?" Get it?

Thanks guys. After driving and tuning so many turbo cars I've walked away from some thinking "ugh, could have been so much better, not if more money was spent but if it was just distributed differently".
On the other hand, I've driven some cars that were just fantastic all around.
In terms of specific combos, what I'll say is I have no problem telling you what I would generally build for myself for various power levels. Again, it would just be my opinion of what characteristics I prefer.
Give me a little time and I will start a new thread detailing various combinations I like and why.

And that's why my build is going on 4 years now, didn't skimp corners where a lot of people do and hopefully it pays off in the end. But at the same time I'm going off years of reading off this forum and YB and built my car off what I gathered over the years with no definite answers of how it works and what to look for when buying parts.
Thanks Jim, I'm not looking for Andy's or Haiders specific cam info etc just generally of what to look at. My buddy has your TU2 cam in his 383 ls6 with a precision 78mm turbo and with your base tune it went 9.90's.. now that's impressive and shows you guys know turbo ls cars.

Not saying that as of Myself cause I have two a bullseye 80 and a On3 78. I'm just speaking for the budget guys out there. If they want to build budget build cause they love going fast as all the rest of us then why not, if they **** **** up for buying cheap **** than that's also there issue lol. I know I useto be one of those budget build guys cause I don't like spending thousands of dollars on one thing when I can have something else of less price that gets the job done the same way.

In a perfect world everyone would have an optimal high efficient setup..... Ive done a lot of testing and tuning to get where I am... and I can say that most people I talk to when I have a question or inquire about a part... they are clueless but give me an answer anyway. lol. Lots of misguided info leads people the wrong way. Thats why I usually listen to no one. I'd almost rather figure it out myself.

Great post Jim!
I get lots of PM's with questions and people wanting help. I'd like to add if you got an auto buy a good converter! I can't tell you how many times I see people build a setup and try to use a cheap converter after I told them to buy a good one.
Personally I still tell people if they want sub 700rwhp the tc76 or tc78 is hard to beat, it won't make high rpm power, but it's cheap and we've never had ANY issues with the tc turbos, they've been dead nuts reliable. I think 95% of the turbo street cars don't need more than a good 7675 on them, it's enough to push even HEAVY cars in the mid/low 9's, but people seem to still try to go to an 88 or bigger just to run high 9's or low 10's, I never understand that.
JY L33, gt2-3 cam, I made 855rwhp on the 7675 thru my auto/9 inch/33" tires, went 164mph with that in my rx7, 168mph with more turned into it, but never dyno'd it again, I'd guess it was just over 900rwhp though, with a stick I think 950rwhp is doable!

I don't know if he was joking or not, but I don't see how you could make 950rwhp with a PT7675 even through a 6 speed on a 5.7 LS1.
875rwhp-900rwhp would be possible with a good set of heads and intake, but an unlocked auto is going to be around 775-800rwhp maybe 850rwhp. This is on a generous dyno.

Lol.. Cars like that have always been around. I always see one or two at the track, even n/a ones...Like a tricked out car w/ a BBC in it, aftermarket everything, got their own pit crew, pushing it in the lanes with the hood open, their own dedicated guy to line it up at the light, Looks like it runs 8.90's and everyone is just waiting in anticipation to see it go and then busts off a 11.99 just screaming down the track and their whole crew is cheering. There are people that can make cars slower with performance parts... they too now dabble in the turbo ls world.

Look no further than a S400 chassis turbo with a 92mm turbine wheel or 96mm turbine wheel for 90% of the majority of the guys on this section. I'd prefer the 96mm wheel each and every time though if the cam is right or close to being right, but if space is a concern the T4 92mm is my second choice for 5.7-6.0's.
A 5.3 IMO with the same stroke as a 5.7-6.0 should still be turbo'd as a 5.7-6.0 because of that.
A 4.8 on the other hand, a 87mm turbine wheel would be ideal IMO.
Cams are a touchy subject. I would be more than willing or happy to go over any cam specs or anyone's particular combo or current combo on here via PM, E-mail or just call the shop.
If anyone has a particular specific question that is easy to answer here on the forum....I'll see if I can answer it and put it in terms everyone can understand.
Skinnies what kind of dyno was this on that you made that power?

People who buy the wrong parts are usually the ones who ask questions and are told to try a search, I know I'm one of them. When we search we find a build thread identical to our goals and then the ******* go th400 or 4l80e while I'm stuck with a T56. LOL this forum has a lot of useful information
