Why not just sell the turbo that comes with the aps kit and get a bigger better turbo? Then you wont have a problem making power. Put this under there and you will make way over 500hp

 

ultimately that is probably what i will do. however i think that fitment will be my biggest challenge.

 

Yea fitment sucks on these cars, oh well its nothing a sledge hammer cant fix. Im going to be fabbing my turbo up with a t04b its about the same size as a masterpower t70.

 

LOL. APS ST isn't a bad kit at all, and I think we'll see some impressive things come out of the ST crowd this year... The only thing I'd address are the actuator springs and internal wastegate. With the external wg pipe and a good set of springs, I think it'll definitely be do-able.

With your setup, the CJ fuel sys you've got mapped out, and a few "adders" to the APS kit, you're definitely in the running to break through the 500 wall.

Drop a 100-150 shot of nitrous on top of that, and bingo... ST turbo setup hitting 600+ to the floor.

But again, most people aren't thinking in those terms... It'll be interesting to see what you put down this Spring

 

yeah i didnt mention the external wastegate part. i will be utalizing the APS externaly wastegate solution for the ST kit as long as it is available or have something comparable fabricated.

as soon as i get the car i will do a complete write up.
eveyone paypal me some money so i can get my car sooner.

 

Good point about the sledge hammer... .

I think that a t04b will definitely put you there in terms of power, but the big question mark is fabbing up the rest of the kit. I'm too much of a chicken **** when it comes down to this level. I'd rather mod an existing kit that's been put through the ringer by an aftermarket vendor.

I'm also still curious to see what TN drops (if they ever get off their a$$es) with the mysterious stage 2.

All of the "holy **** that's fast" supras run massive single turbos. Granted, their power curve usually sux a$$, but top end they've got it down. If we can just get these VQ's to rev to 8k reliably, I think we'll see some insane single turbo setups... Besides that, didn't Injected's show car put down over 700 using a single GT42R on a stroked 4.3L? Sick...

 

Well you know all the people on here that complain about lag its only lagging in first gear when you shift to 2nd gear your rpms dont drop back to your 3200 rpm peak boost.... So when your getting on it your never really below 4000 rpms except in first gear. I want a turbo that builds full boost around 3700-4000rpms and holds it untill 7k rpms. All i need to fab it is some mandrel bends and im already ordering some parts to fab it up, we will probably start fabbing in a few weeks once i get everything i need. So you then have 3krpms of crazy power to play with. It will be like a rocket.

Nice. I'm sure it'll be sick when it's done. Seeing that you're running a revup with the s7 cams, it'll be interesting to see what you end up putting down and how the power curve plays out... Keep us posted

 

I have one of these coming the mail, it makes it real easy to mount a turbo.

 

Keep me posted, i think i just made you my role model....lol.

 

Just for the price comparison..

If you were to go CJM S2 Fuel system at $1185 you have a stainless hardpipe under the car, an adjustable regulator (w/ gauge for setting pressure if you dont have one in your cabin), and fuel rails that allow you to fit almost any fuel injectors you purchase. The fuel pump will cost you $100 tops, and if you wanted the same injectors that APS uses they are only $360 retail for the set. You are left with the factory fuel canister, which when modified correctly with our kit allows you to use all the fuel in your tank flawlessly with no reliability issues.

That puts you at $1655 for the fairest comparison, or with DeatschWerks injectors $1695.

The APS Extreme kit advantage is that you have an extra fuel pump, but injectors not large enough to fully utilize it anyway, and you cant fit in taller Denso, Precision, RC, or just about any other injector Fuel pressure is not adjustable. It also uses softlines thru the entire system. To this date, it has not been proven yet. I dont know what it costs, I think around $2000.

For a ST kit, I see little point in the twin fuel pumps as the turbo cannot support even what a single pump is capable of.

I am very biased Yes the CJM kit is more expensive for the individual component count, but its made in the USA, and the fuel rails are rifle drilled and machined out of billet (so you can fit almost any injector) rather then $10/foot extrusion, therefore its much more expensive to manufacture. The question you are left with, is it worth $300 dollars to you to have a second fuel pump that you will never use with your ST kit?

 

isnt the walbro pump that comes with the aps kit good enough?

and yes, if it doesnt work i know where to find you.

 

You are correct, that is why we do not include another Walbro pump in the systems. Because everyone already has one anyway. The pump that came with your ST kit is the same pump that we would tell you to install if you were starting from scratch with a tuner kit or such.

The GT3582R which is used in the APS Single has put over 600+ whp to the ground in a number of applications - anyone who says it is a turbo not capable of making good power simply does not know what they are talking about. Granted it takes an extreme build to make such power, but I know a few individuals personally who are making more than 500whp on stock DSM heads with just HKS 272s with this turbo and one making over 550whp (FWD).

Now I don't know a thing about the APS single turbo kit as far as the rest of the kit goes, I've never seen one in person, but the turbo itself is capable of flowing enough air to make FAR more power than most people seem to give it credit for on here.

 

^^^^
While I am not too sure as to what affect the piping length has on the overall power capabilities, the APS ST for the 350z has quite lengthy piping which means it needs more CFM to pressurize to a given pressure in comparison to a short length of piping. That could be one of the possible reasons for the lower HP #'s.

Then again that whole statement might only make 10-15hp difference in the end for all I know and more relate more to lag than maximum horsepower.

Regarding DSM's. What was the redline on the car you refer to? Compression? Octane rating?

Not saying that I don't believe that you have validity to your statement, just want to get some more info to reason with.

 

where is this info comming from?

 

Measure the wheels in the aps turbo and it will tell you what it is and how much power it will make. No one that i know of has measured it...

 

People are haveing issues with the extreme fuel system kit. This is why I decided to go with the cj motorsports fuel system.

 

I have no idea about any of those specifics, they are friends of friends, a couple guys on local forums, a couple customers at work. It sure as heck wasn't on pump gas though - no DSM guys run pump gas unless its with water/methanol/nitromethane injection it seems.

 

the 600whp GT3582R dynos? I knew of one in particular off the top of my head, AMS's 622whp 3582R car, and then I googled and quickly came up with a couple more, a couple supras that made 640+, one that made 620, a honda that made 613, etc.
