Hey guys, I finally got my AP-X kit from Will last night.
I just opened the box just to take a quick look., tomorrow I will dissect it, meaning that I will wait all the parts individually to see how much it adds up in the end.It's pretty heavy,that probably will affect my current suspension set up.

I will also post pics of the kit and install, not sure as of yet if I will run meth but if I do it will only be a the track, I will probably run two maps for this.

TTY soon,

Do guys run that 40R on rotaries?

Also noticed you commented on weight, I doubt it weighs more than the stock exhaust and cats that it replaces.

Power?
not sure not looking for much, it will be a track car more than street car.
So something between 400-450 would be realistic goal with stock engine that has 170,000 miles on.

What happened to the custom build?
Well, the car spent last winter at Rob's and before we started with the built he had to take care of oil and coolant leaks that were everywhere under the car, and that I didn't check when I bought it.

While doing that Rob decide to drop the engine and do timing, water pump as well as every single gasket and seal in the engine, as well as refreshing the transmission syncros, he also baffled and bunged the pan.



That took time, then he got busier, so I decide to pull the car out of the shop and start driving it.
It was more of a project that it was going to take time, and I didnt really wanted to wait.

So I decided for Will's kit in the end.

AP-X turbo kit weight brake down.
Pretty light for the amount of power it makes.
I chose to go to with the SS lines, borla exhaust and upgrad it the wastegate to a precision vband for easy access and of course a 4088R turbo.

NSX turbo kit weight:
Straight lower line: 4 lbs
Upper bov pipe: 2 lbs
Fender pipe: 4.5lbs
Intake pipe: 2 lbs
Intercooler : 8lbs
bov : 1lbs

Hardware and fittings: 4lbs

Oil pump: 2lbs

Y pipe/wastegate : 10lbs
Dump pipe: 1lbs
Exhaust tips: 3.5lbs
Exhaust body: 12lbs
Turbo craddle : 3lbs
GT40R: 22lbs


Total weight: 79 pounds.

Cold side:

MSR,
Thanks a ton. I wanted to know the total weight but got a little excited and started installing the kit before I weighed it.

Now my input to this, I just weighed my stock exhaust and cats (from my 97) I knew they'd be handy one day....
Cats 20.2 lbs
Exhaust was 48 lbs

Total of 68.2

So installing the turbo kit only adds 10.8 lbs to a stock car. Um, for the extra 175 or so rwhp I think I can deal with it.

It seems aluminum would be a better choice for the cold side pipes. Lighter and would dissipate heat better.

I've heard this argument before, while aluminum is lighter, and may dissipate heat faster, the problem is that it also absorbs heat faster too (I want to note that the pipes are not meant to dissipate heat and realistically play no role in doing so)

- it is also not as strong and does not look good for as long unless you coat it somehow (further cancelling any cooling theory).

I have built turbo kits for over 15 years now and have used mild steel, aluminum, stainless, even rubber hose too - I personally like stainless the best.

I can make the charge pipes in any material you wish if you request it - although I recommend the stainless.

I guess, But it would rise the cost of the kit I think.
Plus like will said, aluminum its hard to keep clen and looking good.

For 8psi or so of boost that this cars are running I would'nt worry about the piping getting too hot, My last car used to run 32psi on track days with SS piping and the pipes would stay at a decent temperature.
And those 4G63's do make a lot of heat.

It'll be just fine.

MSR,

Leaks when you bought it?

Not being S&$tty but you, me and my techs looked the car over before you bought it and there were no leaks. I think that statement is a bit far fetched. Leaks can form at any time. I assure you if your NSX had coolant leaks you would not have made it from Cincinnati Ohio to Canada with no issues on a 180,000 mile car.

On a lighter note I am happy to see your coming along with the car and can't wait to see the finished product. I know based off of your previous builds it will be badass!

I wish I could buy stainless steel bends at the price aluminum bends cost...

Stainless also does not dissipate heat like aluminum... nowhere close actually.

To increase intake temps because it's hard to keep the aluminum clean isn’t a good enough answer to me to not look into aluminum piping.. my $.02

Nice build and good luck

Its not a problem at all Brian, you are awesome guy, but there was coolant and oil under the car by the time we got it on the hoist.

That is the whole reason Rob decide to drop the engine en change all of the seals*.

Like I said, I have no problems with that all.
Its a car with lots of miles on it, I picked up the car from you when, on march? it didn't hit the hoist until Dec. so it could of happened trought all those months, who cares.

Wow those are definately some leaks! I just can not imagine that leaving my shop with them we are way to careful as many here can vouch for. Glad they are all fixed now! Have fun with it. Turbo NSX's are VERY fun:biggrin:

Goals of 400-450rwhp are easily doable with the AP-X kit. 7 1/2 to 8lbs of boost will get you right at 400-415hp with the stock turbo and a proper tune. I would probably recommend shooting for that power and driving it for a few hundred miles. This will give you time to sort out any type of issues and make sure you are seeing stable AFR's under 12. (more like 11-11.5)

Once you are comfortable, bump up the boost, adjust your tune and HANG ON! :eek:
 
Thanks guys,
Yeah I will probably that, tune straight turbo and get used to the car, I was just getting used to it on N/A mode at the track.
But you know how it goes, one just can't wait.

The truth is that I just missed the boost.
Hopefully everything goes smooth... But it never does.

To nit pick, you mentioned the headers twice. :wink:

Nice build, and I know what you mean by it getting costly. After seeing you mod list, I think I might start my list to see where I land.
