Hey Blympie and all. There's a real looooong thread on the APS single turbo over on 350Zmotoring.com in the FI forum. Go to "forums", then "modifications/technical", then "FI". It is very informative and supplements what you're hearing over here. Peter has a LOT of posts on this thread over there and it will answer many of your questions. Like it did mine. Good luck. Maybe by the end of the summer we can start an APS 350Z club. Just a thought. Good luck!

 

they don't show anything on the website.. they just show where the turbo is located and their exhaust system.

How about some pictures of the manifolds, how they are joined together, how all the charge pipes are routed , how the oil drains from the turbo (because from the pictures the turbo looks like it sits a little low), etc etc

 

No problem and I can confirm that the APS intercooled single turbo system will have an MSRP between $5500 to $6000. The APS single system will be a very complete system, in many ways it's the same as the APS TT system only with one large turbocharger instead of two smaller turbochargers.

The APS single turbo system will incorporate a Garrett dual ball bearing water cooled GT series turbocharger. This large GT series turbo provides awesome power and vastly improved turbo response in the low to mid rpm range over conventional sleeve bearing turbochargers.

The APS single system will also include a massive air to air intercooler, high volume air cooled oil pan, a comprhensive fuel system with full fuel return and pressure referenced fuel regulator, engine management to control, ignition timing retard, air fuel ratio and map boost pressure, blow off valve, 3.5'' stainless steel down pipe, in fact all of the same high quality engineering and features of the APS TT system.

If all goes to plan shipping will commence late May/early June 05 and there will be an optional high flow APS cat converter for the guys who need to run the federal IM-240 hot engine emission verification test.

I hope this answers all of your questions and I will post more info over the coming weeks.

Thanks

Peter

 

That's all good news, Peter. I look forward to seeing the finished product.

I do have one question about the APS cat and the IM-240. Here in Arizona we have the IM-240 requirement (for vehicles older than 5 yrs). Is APS going to verify/certify that installing the APS cat will make the vehicle pass the IM-240?

On a related note, has the TT kit passed CARB?

Thanks for the info.

 

damn 3.5 downpipe, thats pretty big. Must be a big turbo.

 

alrite boys and girls....time to save up the dols. I am looking at the low end of 9K for the turbo kit and the installation, and some sexy gauges. No more beers from now till the end of june. damn... all because of turbo.

 

I'd say around 370 to 380 WHP on a dyno jet depending on the performance of your current exhaust system.

Peter

 

Thanks Peter! I know I asked this of you in another forum but can you compare the torque curve between the ST & TT kits? Trying to find out how much sooner the TT torque kicks in before the ST.

 

I have not been on the forum for awhile and just started looking at this post and was interested in it. I just wanted to know if you can still keep you dual exhaust with this turbo kit or does it have to be a y-pipe back one. If so, do you think it would be possible to make a dual exhaust fit this turbo setup. THanks

 

Sorry if this question has been answered before but is APS going to produce their own strut bar with the development of the Tall Boy Plenum? If so, what is your ETA for this to be released & is APS ever going to do a full APS package deal with all their goodies including exhaust, cats, plenum, strut, & TT or Single Turbo kits?

Thanks!

There's no way that a company can 100% certify that a any FI engine will pass a IM-240 hot engine emission verification test as this depends on the actual condition of the engine when 5 years old.

If the engine being tested to the IM-240 hot engine emission test has worn rings or a leaking inlet/exhaust valve I can just about guarantee that a 5 year old engine in this condition won't pass the IM-240 test.

That said if the FI engine is in good shape and the engine is in a healthy state of engine tune (new spark plugs, clean fuel injectors, efficient cat converter, etc,etc,) then i'm 99.99% sure that the APS single turbo system will PASS the IM-240 hot engine emission verification test with flying colors.

APS have not yet tested the APS Twin Turbo system to the CARB standard though we hope to do so by mid year, we have conducted preliminary engine emission testing in Aust (to the CARB emission standard) and all is looking positive to date.

Thanks

Peter

 

Your right, the 3.5'' down pipe is huge for the VQ 3.5 litre engine. The GT 35 water cooled dual ball bearing turbo is a monster turbo and supplies very high mass air flow at relatively low boost pressure.

Thanks

Peter

 

so how about some pictures of the manifolds, how they are joined together and how all the charge pipes are routed.

 

I was still wondering if you could use a dual exhaust with this setup or be able to modify it to work with the Single Turbo Kit. Thanks

 

aps offers a special pipe that will allow you to mate up the down pipe with a true dual exhaust. there are pictures, or maybe just one picture of the piece on the website.

 

I'll post some power and torque graphs for you in a few weeks time, I'm testing a new design turbine housing on the APS intercooled single turbo system at the moment which may well improve the low to mid range engine power, I need a little more time to complete the testing.

Thanks

Peter

 

You should be able to retain your dual exhaust though this depends on the flange connection points, have a look at this pic which shows the stock 3.5'' APS down pipe (supplied in the APS single turbo system) this should clarify the issue for you http://www.**************/350z/single/it_system.htm

Look at the 7th pic down, this shows a connection back to the APS true dual exhaust system, hope this makes it clearer for you.

Thanks

Peter

 

excuse me but you haven't answered my questions. How is the turbo mounted? how are the two manifolds routed? Where are they joined? how are the charge pipes routed??????????

thanks

 

Yes and this product will be released mid year if all goes to plan.


I doubt the APS product will ever packaged this way, rather the parts (Plenum and exhaust) will be available as seperate components, hope this answers your question.

Thanks

Peter
