No sense telling you to stick with N/A and go bolt ons because you asked which one between the two.

Turbo - More power over SC. Spent last Saturday with a GTR and two Fast Intentions turboed Z's. Insanely fast. Plus - the builder of these turbos are reputable. Their kits can give you 600 + easy and told that it is even more on a built motor. Stay away from GTM if you decide to boost. You already know that other parts need upgraded so it should be already in your budget. You are in Bakersfield. That is an advantage for servicing and maintenance. FI is in Simi Valley and their tuner is in Canoga Park. There are must do tips to keep your car in shape once you boost. Rather that starting a thread - contact TerribleOne, Hotrodz, GeauxTigers1, RoyaltyB and 37 other guys and gals with this kit and ask them what their experience has been like. Each will be different. Common denominator will be the quality of their product and support you get from the builder. Good luck.

Just remember what was said here, the Stillen has issues and was stated its going to cost you and additional 5k just to get it right so go Turbo would be smarted IMO. Also make sure you have 10k just sitting around for if and when something BIG breaks, It will happen at some point. Just don't want you to think you will go FI and nothings going to break :/ .

been there man, Like 90% of us here

The stillen kit doesn't have issues. The guys that buy it do. They want to get major league power out of a kit that was not designed for that. Then by pushing limits things go wrong.

Going FI is a night and day difference no matter how many NA mods you put on. Yes you can make the car a little faster with bolt ons but you will never say, Wow! this is fast! unless you go FI.

If I were in your shoes. I'd get a used SC kit. They are easy to install, maintain and you will not need to mess with exhaust piping. Pick up a cheap used stillen kit and keep it at the level it was designed to perform at. Easiest way to pick up enough power to put a smile on your face.

HOWEVER, you WILL want more. Resist the boost crack pipe. But nobody can.

I still think the way the stillen kit has the maf before the compressor is a major issue that leads to problems down the line.

It does

What are the issues with the 8lb pulley?

It doesn't matter what pulley you have on there. As the kit ships, it measures air temp and flow before its compressed, heated up and fed through a pretty shoddy intercooler setup. How is the ecu supposed to accurately add fuel when the measurement it bases that on is no longer accurate?

It should have been designed as an air to air with a blow through maf from the beginning. Sasha's upgrade setup should have been the way it was done from the beginning. It's a good blower, just bad plumbing from stillen.

So wheres the proof that at 8lb the stillen setup has issues? Yes, pull through will not be as good as blow through but were not talking going to 14lbs here.

The kit was designed for 8lbs max and the pull through works at that. Are you saying it doesn't?

The plumbing from stillen is absolutely fine and the design cools the charge enough as designed. In fact, the plumbing keeps pressure drop to near 0 so produces less heat.

And Sashas setup doesn't work. I know first hand.

So you're saying that at 8lbs the kit does not heat soak and pull timing? From a design standpoint it's flawed. That doesn't mean it can't work, jut that it's far from ideal. I'm convinced they did it that way to get the CARB cert. if they didn't have that to deal with, I doubt they would have made some of the compromises they did.

You're right, if you don't ever plan on pushing the kit it can work. I'd still replace the heat exchanger for a little peace of mind.

Oh absolutely you can improve on the design from stillen. Then again you could improve on just about every kit made.

I am simply getting back to the topic of this thread. You can put a stillen kit on, and it will work. It will give you more power. It will be much more power than bolt ons. It will not cost a ton to buy one used. If I was OP this is what I would do.

So we don't get to off topic in this dude's thread, can you elaborate more on this statement in your 'Air to Air' thread? Last I saw you ran out of blower on the dyno just shy of 500whp. That doesn't seem like something that 'doesn't work'. Did some other issue pop up?

not to go off topic but there are guys who blew there motors on the stock stillen kit.

back on topic. :)

Edit: just seen you wanted me to write in my thread. Gotcha, sorry.

Yes I can. I bought Sashas pipe. It didn't work. Well it works if you want to go to 5K max, then the mafs max out. I used my original Y-split pipe design. Nothing on my car is from Sasha.

You are referencing my thread. Have you read the part where I designed the Y and used it?

There are motors blown on the 8psi pulley? How many? Any threads on it?

I would like to see what went wrong there.

Yes. But that's the MAF maxing as a constraint on the pipe size chosen, not a function of the concept not working. If you increased the pipe diameter it will worked. I would chalk that up to R&D on a new design, not round file it as a failed concept.
