I know that there is a performance list for the srt6 but what about for the na? I want to find a complete list of every mod and price for the na xf.. any help is greatly appreciated!!

 

Try looking at TVT_design TVT250 mod.

No i mean something like this list for the SRT6

http://www.srtconnection.com/forums/...ead.php?t=3105

 

yeah since i only own a srt-6 i know all the mods mainly because of Toy who made that awesome list but i know nothing about the list for a na xf. what kind of power can those things get up to?

 

I'm willing to bet with enough engineering we will eventually see a 300hp NA.

there are many parts available for the limited, but right now the srt6 is a better buy vs $/hp

some of those parts listed for the srt6 will also work on the NA

 

when you say 300hp do you mean whp cause thats not bad or crank. if you are saying crank thats not to bad that is 350z power

 

Your list as of yet:

www.schrick.com
www.tvtdesign.com (Much cheaper if a group order)
I believe Turner Motorsports carries them as well


I think that about covers it as of right now. I'm sure I'm forgetting something, so feel free to add it in there.

 

lol, crank of course. unless you swap rotating assemblies from a SRT into the limited block and bolt on vortec or somethng

don't forget sway bars and shocks.

StaRTECH for those with more money than brains.

 

TVT_DESIGN,

Thanks for the list. I've added it to the Market Place forum.

 

Wow, tvt thanks! Thats exactly what i was looking for! This helps many others too im sure.. Great job!

 

That's too easy to do if you consider NOS. I was at 298 a year ago, then added dual exaust, NGK wires and I will be most likely getting injectors and another tune.

 

hey tvt... do you have anyy prices on those mods? i can only find a few on your site and none on the others..

 

Lets add to TVT List:

Cold Air Intakes +8HP

Custom made Free flow exhaust 3" 20HP

ECU Tune (POWERCHIP Custom 100 octane) plus 7 point octane boost to 107 points 35HP Minimum

Injectors (allows for more HP) 2-3HP

Ignition Wires (+5HP) Dont know bigger spark bigger bang

NGK Spark Plugs (better idle, possible HP increase)

Underdrive Pulleys +6HP

Modified Airbox/Hi Flow Filters +10-12HP

Camshafts +15-20 but expensive

TOTAL N/A Standard here in Australia 212HP

Total mods above 104HP total

316HP at the crank

Nuff said

It took me a little over an hour to gather all of these prices so i hope that at least a few people find this helpful!

 

it doesn't quite work that way Hugo, adding up numbers sound logical, but power adders that make HP in this engine might not work together with anoth performance part, then you have to change the ecu mapping for a certain power adder, which may detract from another parts performance. It's not just simple addition, but I could be wrong.

 

I agree with Maxwell.
A lot items of performance figures are just one single item against an unmodified angine.

For example:
A new CAI may let the engine breath better and gain you 5hp.
A new exhaust may let the engine breath better and gain you 5hp.
However, if you do both mod's the engine can not breath the same increase twice, you may only gain 8hp with both mods.
The engine is only a glorified air pump, it can only move so much volume of air - hence turbo's & blowers etc.

 

With all the mods listed you may be able to squeeze 300HP at the crank, the cams are the biggie. But you will need larger injectors then the ones we currently sell.

 

Just to clarify your HP quotes here: an exhaust will add 12RWHP at best with a properly built dual exhaust, cat backs normally gain around 5. The ECU tune wil not you no more then 18RWHP without larger injectors, regardless of the octane you use. You can't make power without the fuel. Just an example with the injectors added to the CAI and ECU tune we picked 29RWHP, from just adding injectors. That doesn't mean injectors added to a stock motor will add 29HP, it's a ll about harmony.

With a spot on tune and the stock intake and exhaust manifolds, 300HP will be extremely tough to get, but doable. A new manifold and headers will really wake this engine up.

 

So when are you going to make them then? lol

 

Sorry guys just belted it out but to clarify the figures I added to TVT are the ones quoted by the specialist engineers that do my mods.

All have been designed to work together, which is why I'm kicking the Porche and Lotus buts on the track

"Just to clarify your HP quotes here: an exhaust will add 12RWHP at best with a properly built dual exhaust "

Properly built removed cats mandrel bent estimated but not Dyno proven

The ECU tune wil not you no more then 18RWHP without larger injectors, regardless of the octane you use.

ECU Tune made without emmission restrictions if you take the time to read the Powerchip site there are significant gains to be made by Octane ratings and when you take the emmissions out of the equation even more.

You can't make power without the fuel. Hence bigger injectors.
Agreed but the bigger the bang the more the power, hey I might go to Nitro just kidding

With a spot on tune and the stock intake and exhaust manifolds, 300HP will be extremely tough to get, but doable. A new manifold and headers will really wake this engine up.

Headers are in the process of being bent now, intake is being looked at to see if we can open it up a bit but retain the appropriate swirl and internal finish to aid combustion.

As said it all adds up to harmony, but if you have the right people who are SPECIALISTS in their individual fields it is quite doable. (is that a word?)
BUT you have to find the right people.

Having said all that we are now looking into the Vortec side of things and fuel ratios and delivery are critical here. The Benz guys have a bit of an idea I am using Harrop engineering here for dev work. Harrop do a lot of the V8 Supercar intake and engineering work here so we will see what they come up with.

Hey it's all fun
