Best Choice Of Motor?

I have always lived by don't build anthing you can't afford to lose.

Are you retarded?

Im not the one who owns a R34 4 door, just sayin

Buy a stock neo and don't touch anything on it, as soon as you open it you've made it worse.

add a highflow, injectors, afm, ecu, clutch, tyres and you are back about $6k already and this will be enough to kill yourself quite easily, also if you don't open it and tune it correctly it should last forever with ~260-280kw

stick the money in the bank as you go instead and let it earn interest. IF you still want to do up a turbo car after you get off your P's then you have the money there to do it or you can put that money to use some other way if your mind has changed.

someone once gave me some good advice, buy the cheapest car your ego will let you. the more expensive it is the worse it is if you wreck it or parts break.

Agree with the second part 100%

Only wish I'd listened to this when I was 18.

The fact that he can run a very reliable and safe 330rwkw+ all day every day with nothing but injectors, fuel pump, exhaust, computer and a set of turbos or a single on it where as the Neo would be a ticking time bomb at those power levels on an unopened motor..

Were you born yesterday or something??

I'd actually say the 26 is more of a time bomb over the NEO. Especially the R32 RB26.

Not to mention the fact that there is more stuffing around to fit an RB26 into a RWD car.

32 is only a problem because of the crank collar/oil pump issue and assuming he is building the car how hard is it to put a crank collar on with the motor out..

Yes there is stuffing around with the 26 into RWD but after all the guy wants to "build" a motor/car, the more stuffing around the better i say, how else are you going to learn about your car

And the reason to that quote was the fact that I see mates running roughly 300 - 340kw at all 4 wheels on unopened 26's, none have gone bang yet. My other mates 25 just blew a gasket the other week at 270rwkw, sh*t example to be singling out one car but what im trying to get to i havn't seen many unopened RB25's do the numbers and LAST like a 26 does

There's PLENTY of unopened 25's on here making much much more than 300rwkw and have been for awhile now. Simon's comes to mind, as does Methz. There's others but I can't remember everyone's name. On the other hand, there are also plenty that have gone bang with less power.

There is a whole thread on it... 25's....26's.... they will all last if treated properly.... As soon as you "build" an engine, it will only last as long as the builder is capable of making it last

[GTSBoy]

Besides which, the Neo in particular is pretty much the same as a 26 below the waterline. Same rods as 26, shorter stroke so a little less force on the rod bolts. So a Neo should be a better bet than a normal 25 on that basis as well.

exactly, I treat most built engines as less reliable than an unopened nissan motor, unless you go to one of maybe 2-3 builders that know what they are doing.

One way to look at it!

Especially if it is a DIY job, WHICH i am assuming this thread was aiming at? If you were to pay a builder to do it i would assume the OP would just save over the next few years as has been suggested and just get it done.....

Not many see regular circuit though making legit 300rwkw+ (maybe 1-2 days per year and then general street duties). Then add in the couple thus far that have died as well, and it's not a "safe" aim IMO.

A RB26 isn't a 'mystical' beast either and eventually when circuit raced, will get tired when making over 300-330rwkw like others have before them. If people think a 15YO RB26 will last a few years of track work @ that power and not need a rebuild they are really hoping for the best case scenario, because realistically it is unlikely in most cases.

280-300rwkw for both 25/26, keeping boost to 20psi or less on unopened motors that see the track 8+ times a year, seems to be the region that will see them live for more than 1-2 seasons.

[51NNA]

Aside from what everyone has already said about RB25/26's if you have a spare 70 grand in the bank buy a 26B =) 500hp @ 13,000 rev's NA yewwwww

But this is who you should listen to.

Not worth it, too many head gaskets to replace!

As mentioned, a stock rb25det neo woth some upgrades will get you moving along nicely and you shouldn't throw yourself in the deep end with regards to power. Going from a piddly NA on the street to something with 200+kw and not knowing how to control it is a sure way to wrecking something or someone.

[simpletool]

I'd say VQ35HR, then TT (with 2 x 2860).

It will take 50kg out of the front of the car, have more power and torque and last longer. But you'll have to build it first.

I don't see much between a Neo and a RB26 for power/longevity. I'd take a stock NEO for the money with GT30 (0.86) ~280rwkw easy. Once you get over 200rwkw/tonne you're getting into serious grip/chassis issues.

[Country Cruzin]

300kw-320rwkw easy??? spent about 25k on performance parts an labour to get 300kw atw. Prob cheaper if u find a happy dyno or dont tie the car down real tight to allow it to ride up, from wot i've been told it can make the exact same dyno read about 50-80hp different, depending on how u strap it down. As for the longivity of an engine's life (built or unopened) people usually only seem to quote a certain amount of years/months which isnt really informative, amount of track time, km since rebuilt, %of time driving the car spirited (or over 5-6k rpm) would be more informaitive. as a car that only does 3000km a year an 1 track day, an gets babied, is a lot different to a car that does 20,000km a year a 4 or 5 trackdays a year an gets thrashed every time it gets drivin.
