hi


i was going to see which is the best twin turbo kit? the most performance and the best quality.


Power Enterpires

Greddy

JWT

APS



also how much boost can the stock engine handle? and has anybody ran at the track with any of these twin turbo upgrades?

thank you

Id say APS. Have you tried looking through the forced induction section?

 

there was a post a few days ago!!
it was a scanned article where Vortech, GReddy, JWT, and Stillen were compared.
Use the search button or check out the forced induction section.

 

from what i have heard APS.........but search it there is a lot of information on this

 

I LOVE MY APS! :d

 

There have been a lot of threads on this same topic.....The overwhelming majority have always stuck by APS. I get the feeling this a Pro APS forum...but those of us who have the Greddy TT kit will all tell you pretty much the same thing....The fuel return system supplied with the kit is not on the same level as the one in the APS kit. I had to go with a Walbro unit and 660cc injectors and hi flow fuel rails....etc. However, it should be noted that the top hp car in the FI forums is on a Greddy kit. The Greddy kit doesn't get the same air flow through the stock bumper that the JWT one will give you, but I think that air flow sutff is a bunch of bull. In terms of which kit looks best after installed in the Engine bay...the JWT kit looks like pipes are running all over the place, the Air filter is pulling in hotter air than the APS or Greddy. The Greddy and APS kits have individual filters for the individual turbos...The JWT kit has one air filter that splits to each turbo. But my best suggestion to you is to get online...there are plenty of sites who have reviewed these kits and will give you the pros and cons of each.

 

You forgot SFR kit too!!

 

I think greddy was the top HP car.

trust me, this isnt a pro APS forum.. matter of fact APS is banned from the site

 

I think he was referring to the readers and not the admins.

 

I don't get it, this link is to an APS car.

 

Yeah sorry I didn't specify...all the readers seem to think that APS is the end all be all of FI. I think they see the big numbers those kits are putting up at 8 and 9 psi on stock internals and get excited. What they don't seem to care about it how long their motor will last. The stock boost on APS is 2.5 psi higher than the stock boost on the Greddy kit. The Greddy will make less power out of the box, but man will you be happy 6 months from now when you car isn't in the shop with a thrown rod. LOL.

 

The APS TT is the most complete out of the box, but you can spend the money to make the other kits just as complete. In the end they will all come with in a couple of hundred $$ of each other. The only thing I think makes the APS TT more superior is the ball bearing water cooled turbos, which are supposed to spool up faster and last longer.

APS is coming out with a tuner kit soon and if it would have been available when I bought my kit, I would have gone that route and bought my own fuel system and engine managment. IMO the fuel system that the APS TT kit comes with is not all that. It isn't even a real fuel return like the AAM or CJM. If the tuner kit was available when I was making my purchase I would have bought that along with the AAM or CJM, RC 650 injectors, and an Emange Ultimate.

 

That's hilarious! How about a guy that's been running 500whp on his APS TT Z for over a year now with no problems?? He let's his customers take it out and beat the crap out of it on test drives all the time. Other Zs have similar tunes with close to that whp and again no problems for thousands of miles.

What makes you an expert on what the life expectancy is for a APS TT Z/G on stock internals? Show me examples of any APS TT Z/G throwing a rod after running stock boost.

 

Oh the pro APS mentality comes out.......I think we are all familiar with exxageration. So let me state my above statement in a factual manner. The additional strain placed on the stock motor with 8 psi or more of pressure reduces the life of a naturally aspirated engine. I think we can all agree with this. The real queston is, How much life is taken away? I would agrue that if an engine is supposed to make it 250,000+ miles before it goes out and a TT kit is applied to it the life expectancy will come down. At 5.5 psi (the Greddy kit) the strain applied to the engine internals will reduce the life expectancy at a lower rate than the 8 psi (APS kit) when applied to the same internals. With these facts....without intervening with this trend (i.e. building the motor to increase the total available miles out of the motor) a motor with the APS kit will inevitably fail ON AVERAGE before the same engine with the Greddy kit.

*Note this implies that both kits are left at stock boost with identical surrounding mods, driven in identical temperatures and are driven in the same manner.



Instead of saying all of that....I chose to be sacastic and finish this theory lesson in a few sentences....My bad and for future reference I will be sure to fully eloborate on all of my posts.
