Few Questions About The Na

[nuddy989]

hey guys couple of questions..

as I am stuck on p plates I'm unable to drive a turbo car :(

but I only have about 8 months to go till I can and im wondering what I can start doing to my car to get it prepared for a turbo. Am I able to get better valve springs and pistons now that will still work when putting a turbo on the car? also If I change the cams to suit my na (crow cams) will they still be fine when I turbo the car?

I also know that the na motors have a higher compression ratio then the turbo motors which means I can't run the boost as high without damaging the motor, but if I change the valvesprings/pistons will this make a difference? also what is involved with decompressing the engine to be able to put more boost into it?

sorry if I asked some noob questions but Im only fairly new to this whole modding of the car thing lol.

There has been a few topics on this before.. if the search is working have a look.

Or I did one for you:

In a nutshell: I wouldn't bother touching an NA. The cost and work far out weighs any gains you'll get. Plus resale will fall, your insurance comapny will send you death threats, your mates will pretend that its a great idea but think you're an idiot, and any modded factory xr6t will leave you every time.

Sell the car. Buy a Turbo. Job done. No headaches. Money Saved.

While seduced is correct, you will see alot more power from an original turbo, however some people get attached to their cars and may have already spent lots of money on suspension, exhaust wheels, ect and get sentimental, he may not just want "sell" the car.

Turboing the NA engine can be done fairly cheaply if you hunt around and are patient waiting for 2nd hand parts coming up on ebay.

RDP in Brisbane just did a conversion on an XT with over 250 on the clock recently with good results from 176rwhp to 300rwhp with just bolt-ons and a tune. you can see the resultshere

From memory, this conversion cost less then $5k in total.

Very true, it depends if you're a purist or not. Turbo conversions just always have that tryhard feel about them... they may have the power, but they just dont have the pedigree somehow. Like a done up GTS skyline sporting GTR badges.

"nice car man, is that an xr6 turbo?"

"nah, its an XT but I've bolted on a turbo though.."

"......oh.....cool."

[ratter]

it may or not may not concern you, but I thing to be close to legal you would have to get it all engineered and tested for emissions etc and upgrade the drive line.

It would be far cheaper to trade and buy the turbo whan you can afford it and then have less problems with rego, insurance etc

[nuddy989]

oh okay well thanks for the replies. I understand that it would be more economical to sell it and buy an xr6t but like it was mentioned I have spent a decent amount of money on it on things that cant really be swapped back to factory upon selling the vehicle. (exhaust/suspension and lowered/interior work)

If I were to buy an xr6t there is no way I would be leaving it stock and I would be spending the money on the engine regardless so I guess I worded my original post a little wrong in the sense that I would be upgrading the stock parts of an xr6t so is there a problem with me bolting them onto my na motor?

yeah its hard to think of selling a car youve spent money on.

at the end of the day though, in reality, what ever money we spend on cars should pretty much be considered unretreivable.

ask a guy who spends 50k on mods to his brand spankin gt and then has to let it go for less.

if you keep an eye on the cars for sale thread- there are plenty of sweet modded cars that can hardly be given away.

there was one recently that had all the good bits on, 320rwkw, starting price was $22,500 and kept getting dropped till $18,500. who knows what it eventually sold for.

whats your na gonna be worth after youve finished? theres one on ebay atm that cant get 13k.

if you wanna go fast, and do it as economical as possible, enjoy your ride as it is until your off your p's then buy a turbo.

it will cost ALOT less in the long run.

[seduced]

ratter sums it up nicely.

Think beyond the engine. LSD, built gearbox, brakes, new exhaust, emmissions, driveshafts etc

Your problem here is you want to turbo an NA and at best you may find 300rwkw after spending alot of money to make it legal, upgrading your driveline, building the engine so it holds....about $10-15k for something reliable and powerful I reckon. But Then you say you would not leave a genuine turbo stock anyway, which means if you did sell and buy a proper turbo, you would replace a handfull of parts and see 320-350rwkw for about $3-4k.

Do the maths. Less time, less money, more power if you just cut your losses and say goodbye to your NA and upgrade. Even if you then redo the suspension, and interior (no real need for exhaust), you would still come out ahead. How much is your sentiment worth?

Secondly, think insurance. What insurance company will insure a 20yr old with a 300rwkw falcon that the only original part is the body panels and dash?

all good points I think I might just leave as is and resell and op for one that's already had the work done to it

Thanks for advice guys much appreciated

[seduced]

Good thinking, all the best with your new Turbo, after you drive it 5mins down the road, you'll be glad you sold the NA.
