N1 Or Rebuild Rb26

[GTR 94]

ok guys its time to put your thinking caps on as i am in a lil prediciment at the moment and it is time to freshen up the old RB and seeing i have just put Trust T517z's and tomie poncams and a few other lil bits i feel that the bottom end is probably in need of some TLC. Just a note this is a 94model R32 GTR with supposed 103,000kms on the clock.

so here are the options and please note that both are going to cost similar amounts but i am aiming for reliability and performance (somthing that is very rare in modified cars).

Opton 1: Full rebulid on current motor meaning CP forged Pistons and ring set, R.E.V I-Beam Conrods, TOMEI metal manifold gasket kit, HI OCTANE RACING rocket cover baffles, NISSAN engine gasket kit, TOMEI sump baffle, Nissan N1 Oil Pump, ARP 2000 Series Head Bolts, RB26 Cam Cap Studs Set and an R33 crankshaft. All will be balanced and blueprinted and some sort of strenthening process applied (cant remeber what its called somthing about freezing it all then zaping it hot again. cant remeber.)

Option 2: Buy brand new N1 motor and put my turbos, cams and a new sump baffle in.

well there you have it all feed back will be taken on the chin.

thanks

ur better off getin the N1 long motor i think they go for about 12k. and sell ur rb26 and buy the N1 coz in the end u will spend alot more money rebuilding and paying for parts etc..

[Atreyu]

If its an R34 N1 motor your cams wont fit it I believe, R34 Rb26's have different head casting so cams dont interchange.

hmm ok thanks guys any more input? any one else?

You can still use the poncams on the N1 , use your existing CAS.

Depending on how much power your after , dont forget N1 blocks are better too .

For 12K you could build quite a strong engine. I would think that a forged bottom end would be stronger than an N1, depending on who built it of course.

[Duncan]

Absolutely, and you can throw all the tricks in the motor when you rebuild it, like oil control and good balancing, checking clearances etc etc. 12k is a lot for a long motor that you would have to open up to get the same level of reliability as a rebuilt one

[GTR 94]

thank you both to NXTIME and Duncan. now we are even at 2 and 2 again thanks guys. honestly i think im gonna go with the complete rebuild, just gives me a little more assurance.

[R31Nismoid]

Go the full Lee.

If your prepared to pay 12k for the N1 stuff... Race Pace will build you something miles stronger than that i can assure you

[GTR 94]

ok thanks ash i like your thinking might give em a call

[markimak]

anything actually wrong with ur motor? 103kms aint too much. RB26 r a pretty damn strong machine. make any funny noises? and did u just recently do ur 100,000kms service?

he is on the limit with the turbos he has on there

its a matter of time, especially if he gets on the track

[markimak]

oh i get ya.. haha still the RB26 is good for over 350 stock.. thats from memory.

rebuild,rebuild,rebuild. cant beat a nice "weatherd" block.

besides n1 engines arnt all the bees knees anyway. apart from the water and oil pump. the pistons are still cast.

sure the block is better, but are you aiming for 1000hp??

just do a rebuild. youl have a much stronger base. with all the fruit and some change to blow at the casino :lol:

[Morgs]

As above; rebuild is a better idea

PS; Whats wrong with your current motor?

[cowie165]

n00b of the day question please:

What is the difference between long and short motor? Is a short motor just the block and the head? If you saw a long motor for sale what would expect to be buying? Includes loom/airbox/etc.?

im 99% sure short motor is just the bottom end complete, and long is head and bottom end without accessories (no manifolds, etc)

just to throw a spanner in the works......if you buy the n1 for 12k and sell yours for say 3-4k, it's not going to cost you 12 is it.

make sure you get someone who can build engines and who has a rep for rb motors. and someone who knows them inside and out.

i beleive someone mentioned race pace.... there is a wonderful start. hit them up with the telephone call and see how it goes.

but i'd also go with the full rebuild. you will have alot more control over what goes into it and the finished product.
