Vortech/ATI? ( I want this boards opinions)

sorry kinda long, just have concerns and questions. Thanks in advance for any help! It will be greatly appreciated!!!! :D :D

ok, so I have read several threads about this topic, but it always seemed to be about 4 people stating their reasons and I want to get other peoples opinions. I also feel like posting on this board will be more benificial since I won't get smart allec remarks when I ask stupid questions, cause when it comes to superchargers I don't know anything. I know most pros and cons but I just can't seem to make my mind up.

Also, If money wasn't an issue, i would go APS; but it is. I am growing impatient and really want to boost my car now. If i were to get APS, I would have to wait a year maybe. Plus, I am just scared to run Turbo kits without changing the stock internals.... so that is more money. This is also my daily driver.

supercharging is just looking more like reality to me and I am really having to overlook my "superchargers are for domestic, turboes are for imports" menatality I guess. I love turboes but have never experienced superchargers....

what I have read about ATI is that if you get the tuner kit and add your own fuel and timing fixes the kit can be great. The blower is better quality than Vortech? The thing that scares me about ATI is that it has blown engines in the past but this issue stated above seems to make a great kit.

On the Vortech I just don't know if it is such a good idea to tap into the oil pan? can someone further explain to me the pros/cons of this? also the air filter location? These are things that stray me away from Vortech. But it seems that Vortech is highly favored.

Basically, I am not concerend with right out of the box as i want to tune and upgrade. I want what has more potential, because I am going to tune it and add things myself. I guess I like the ATI kit because it can produce more power but it seems that everyone pushes Vortech and I kinda feel like I might make the wrong decision.

I know FI is always a "risk" but I want to be as smart as I can about it

i believe with the turbo kits you tap the oil pan also (or they come with a pretapped one) so dont let this sway your opinion

Good post and I understand where you're at and it's also easy to understand (after reading some posts) why some Z owners think that turbos are more likely to be tougher on the engine...............fact is this is far from the truth and if anything a well designed Twin turbo system is easier on the engine than a supercharger system.

Given that the FI engine is tuned for the correct octane fuel, the turbo will be gentler on the rods and pistons at the same power level than a supercharger system. The supercharger needs to produce 40 to 50 Horsepower more at the crankshaft in order to produce the identical turbocharged power at the wheels - known as supercharger parasitic loss.

Bottom line, the APS Intercooled Twin Turbo on the Z engine will be super reliable if boost pressure is kept to a sensible level (around 7 PSI) and the engine is tuned and operated on the correct octane fuel.

Hope this helps. :thumbsup:

Thanks

Can the APS TT work with a G35 coupe?

Have a chat to the guys at MRC and I'm sure they will be pleased to assist you and they live and breathe nisssan 350Z and G35 cars.

In short the APS 350 Z Intercooled Twin Turbo system can be installed to the G35 though a new front air dam/nose cone will need to be installed also to supply sufficient air flow to the large APS air to air front mount intercooler.

I believe therte are at least 3 different aftermarket front nose cones (greddy has a nice part ) which can be easily purchased in the US for this application. :thumbsup:

If you need any other help or advise your most welcome to pm me.

Thanks

I'd suggest a TT kit and I'd say go with the GReddy since the APS is out of your range (I'd go with APS, too, if I had the money). You can get the GReddy for under $5,500 with FMIC (I think Mr B was selling them for $5,100 at one point). In fact, I've seen pictures of your car and I don't doubt you could get a local sponsorship that would do the install or free and/or knock down the price of the kit. Hope this helps.

A very reputable shop talked with me about FI for the 350Z. They are well known esp for the RX-7's. They are known for the Japanese 3 rotors w/single turbos, and water injection. Aslo for their custom made turbo manifolds.

They tell me for a completey stock internal engine, with the high compression 5.5 lbs is safe for daily driving, but with some fuel tweaks you could run a tiny bit more boost. They are developing now a single turbo kit for the 350Z. And cost around 500 dollars cheaper than the greddy tt kit. They mentioned if you run 7+ lbs without less compression your really asking for it.



That car ran a [email protected] at Nopi in Ennis, Tx a few weeks ago.

What does your kit have or do that will allow someone to run 7lbs safely?

hmmm sounds like I need a APS TT sponorship! :D :D :D
I was about to make the same post cat, except I wasnt aware of ATI blowing engines...were they installed correctly?

I was also going to go APS or Power Enterprises, but the price with internals is just to high, so maybe GReddy...
So they are both centrifugal and have been popular lately.... what are the pro's and cons of each one / general opinions of each!! :)

I am leaning towards the vortech but mainly due to popularity so help me out!! LOL


:shiftdrive:
Heard the ATI is more powerful with some reliability problems but some members are getting nice #'s with the Vortech. I'm loving my kit but we shall see how reliable it is because I can't stay off the throttle!
Hey kitty-cat...for whats its worth if i had the $$ I'd go with Greddy but for a little less I chose the Vortech. Her some bad things about the procharger but because of lack of knowledge I can't bag on it. Don't let oil pan tapping be a reason to chose. You can get a oil pan spacer for Wolf and tap into that I believe. Having lots of fun with my Vortech!
Yeah, I am going to wait and save up for an APS kit. It is the best one out there IMHO, so why dodge out and get a Vortech. Although it will take me a little longer to go FI, might as well get what I want right!? ;)
Hey everyone!!!!

whats the general opinion on the two as far as a choice ???? im leaning more towards the Vortech but im goin more towards it due to popularity :) LOL

what makes one better than the other?????

THANKS!!!!!!!!!!!!!!!!!!!!!!!

I just finished my install on the Vortech. Very nice system overall and it ran great out of the box. The car is now scary fast when driving at limit but behaves well for daily around town driving. I chose Vortech over ATI for 3 reasons. I watched an install at a local shop of an ATI and I was not impressed. 1) The blower did not fit well and the car was "modified" to make it fit. 2)Taping the oil pan was a piece of cake for me on the vortech and now my blower has fresh oil at every standard oil change. The ATI unit, according to the same local shop, requires the removal of the blower (3-5hours) every 3,000 miles to change the oil. 3) Vortech is a leading supercharger company with a long and successful reputation. In addition, I have independent studies on the blowers and the Vortech was superior to the ATI. I did my own install on jack stands and simple tools... it was not a big deal if you can read a manual and know anything about cars. The split second timing box can be fine tuned on a dyno (I go in next week). BTW, I agree that the intake fiilters for both units are a bad design. They draw hot air from the engine bay. I fabricated a cold air intake out of my old Injen itake in less than an hour it it looks very good. Anyway, Just my opinion on the Vortech. I don't have first hand experience on the ATI but what I did find out made me shy away.

I think in the case of the intercooler, SFR/SSR engineering has made a twin intercooler setup that you should be able to merge with the APS TT system. The Twin intercooler is made for the G35's split bumper.

Yeah, I am going to wait and save up for an APS kit. It is the best one out there IMHO, so why dodge out and get a Vortech. Although it will take me a little longer to go FI, might as well get what I want right!? ;)
Good decision. If I wasn't going with an N/A setup with Nitrous I would be putting on the APS TT's.
