Thanks! The exhaust is cool, just keep adding things slowly so it's not so noticeable to the wife. Just kiddin' honey.

 

Congrats! We'll definately have to meet up now! My fully built APS TT is almost done, any day now. Just waiting on the final parts. What plans do you have for after the TT is installed?

Tinman, did you ever get your wifes approval???

 

Thanks, sounds great! Can't wait to hear about yours. I plan on running it as high as Tuan will tune it until the motor goes and then build it.

 

Hey KP,
Were you able to get larger fuel injectors and replaced the wastegate actuators to get past 12psi? Or are you waiting for APS to release a larger Fuel kit?

 

Larry will you get it already!!!

 

Brian,
As of now, plans are to build-up the bottom end. However with APS TT, 12psi is max with stock fuel kit and actuators. Which means spend more $ to upgrade APS parts. If Im going to spend all this $, I want to be able to at least boost up to 16psi. Honestly, Im considering getting the SFR/SSR TT kit, its suitable for a built-up motor. APS is still possible, but it just seems they want you to wait for their parts to upgrade current kit. Taking my time, so will see what happens.

 

Just bustin' your chops. I just meant FI not APS. That sounds like a good way to go. Don't rush it like me, I'll probably be sorry I didn't wait for the APS Extreme Turbo Kit.

 

APS Extreme Turbo kit?? More info please.

Currently one of our development 350Z cars/engines is producing 742 WHP (with a number of new yet to be released APS performance parts) and APS techs are still fine tuning this new engine development. I will post more info and pics over the coming months. I guess you can now understand why APS developed the new twin 3 inch exhaust system with twin 3.5 inch down pipes, all good.

Not Garrett GT35R turbos - this info will be available from APS in a approx 2 months time, sorry I can't tell you much for now.

The larger direct bolt on turbochargers are dual ball bearing GT series Garrett water cooled units, an easy install and upgrade for even higher Horsepower.

Most likely, I will let you know when I have final details of the total APS extreme twin turbo system.

Depends on how much power you are wanting, there wil be at least one upgrade package for the current APS twin turbo system which should easily get you to your intended power goals.

I can't say too much now as the project is not completed, here's what I can say,

1) Custom billett crankshaft - we'd like to run the engine to 9000 RPM.

2) Custom connecting rods

3) custom Pistons

4) some cyl block preperation (can't say more on this issue for now)

5) Head work - ported and flow bench tested

6) Lots of intake manifold design work and manufacturing.

At this time we have not spent any time on the drive train, that will come in the future I'm sure.

All of the engine development work was conducted on engine dynomometer as it's much quicker to change parts (heads, cams, intake manifold, turbochargers, etc, etc) on the engine dyno than when the engine is back in the car.

Someone on my350Z has sourced wastegates, so I'm going to go that route. I have to break the motor in, so I still have time to do my research. I'm not sure what I'll do for injectors yet, either. I know that there are some on the market now, which may or may not work with our ECU. However, I am confident that ANY injector can be used with our ECU, if you know what you're doing....

I plan on taking my car to GRD for final tuning, fuel upgrades, retorquing the heads, and upgrading the wastegates, and I would like to stay AWAY from APS as much as I can along the way. They have taken the approach that the APS kit is for stock cars and shouldn't be modified in any way, so I'll spend my money else where. I've asked Peter several times about the wastegates and never got a response.

 

congrats for the third time! lol

yeah it doesnt seem like they're too friendly with the built motors till they get their products out there.. its a little messed up but that seems to be the way APS works. I've already decided since I have this smoking problem that I will be rebuilding the motor with forged internals and everything..its just a matter of time, money, and convenience.

I guarantee once they get their products out there for built motors they'll offer all the support you can ask for.. which will be too late by then.

 

Congrats Brian! I pick up my car tomorrow morning and I can't wait for the fun to begin. Have fun and be safe/

 

Thanks! Congrats back at you! Who did your install? GRD?? If it is, please check on my baby.

 

Congrats, you will love this setup. I had a chance to ride in a aps car last month. 450hp it it felt every bit of it! I say go big or go home! No regrets later.

 

Thanks! Exactly how I felt, I didn't want to regret not going for it.
