Rebuild

[DAS KAMU]

hey,

when it comes to rebuild time does every go straight for forged internals or stay with the nissan pistons if there capable of handling what you need out of the engine?

any pro cons for either?

or does every one just go forged?

[DVS JEZ]

Comes down to budget and usage for the car

[DAS KAMU]

that the point iwas trying to get at

if the end user was say happy with 450 hp

would there be any merit changing to forged?

Upgrade rod bolts, consider forged pistons....otherwise I wouldn't say so.

I know of one GTR that destroyed a standard piston, yet it "only" had 290 kw at the wheels.

Common thought is that high boost plus high revs equals pistons failing, the piston ring lands usually suffer and break.

For peace of mind I would opt for forged pistons, no need to go out and by the $2k "bees knees" jap brands, just something like CP pistons would do the job nicely. Also good bearings, oil pump and restrictor. Standard rods and crank will be fine.

If you have the engine apart then why not spend that little bit extra to get an engine that is strong and sound.

You can get a JE pistons and Eagle rods combo at the moment for like sub $1200!!!!!

Strike while the iron is hot (AUD is high) !

Down the track when you want more power (you will)

All you have to do is up boost

If it's a daily... I'd look at standard pistons with ceramic and skirt coatings. Better ring sealing, lower cost, less hassles. I drag raced on stock pistons at 400rwkw plus nitrous for 2 years as well as ALOT of street driving.

If your going to race often, iffy fuel, hot temperatures, basic managment or push the limmits, then forgies are worth the effort.

And that GTR would be mine heh heh heh

Im in aggreeance with smithy...

if i was to build a 450hp engine id be using stock rods with a set of forged pistons and good gudgen pins, thats not to say that the standard pistons wouldnt handle it alright but you ll probs sleep better at night

N1 pump would be fine with a tomei restricter is a good idea

Though if you can get a JE pistons and Eagle rods combo for sub $1200 like Nee san is sayin id be doin that for sure

If you use the forged pistons you can at least put another 100-150 hp through it if you get bored with 450hp

Also if you plan on pulling a few G's around corners then i also suggest a sump baffle. You can get them from RHD for about 300ish

Heres the piston haha

you will often find that aftermarket rods and pistons will also be lighter than factory, so that can help a lot with bearing life and performance.

Also, forged pistons provide you with a bit more of a safety barrier should you get bad fuel/high temps/blocked injector etc.

As far as im concerned, a lot of the cost and effort is the labour. so you might as well put in some good forged stuff while your are it.

forged it is

[doo doo]

You might as well get ARP rod bolts too with the standard rods, just get the main ends re-sized. What pistons you looking at using?
