My Rb26 Rebuild

[Turbz_13]

gday guys, well i have an rb26 that requires a rebuild. the engine is out and has began to be stripped. so i will be using this thread to get as much info as i possible can. i am aiming to build to make reasonable amount of power out of the engine

the first this i really wanna knkow is about the N1 oil pump. i have been told not to use it as the have been failing people. and also that it will cause a ruch of oil flow to the top end causing the bottom end to be lacking in oil.

will the oil galleriy orifice help this problem?

and any help with this first issue will b much appreciated

cheers guys

hundreds of people are using the N1 pump without problems

Keep your rev limit to a sensible limit and you shouldnt have any problems

If you arent afraid to give the thing a hiding and want more 'peace of mind' then start saving for a Jun pump but expect to pay a little over twice the price of an N1

Ive been using FUCHs 0-30 oil in our 26 builds and find the N1 pump will take anything with good light oil.

are you building it yourself, or are you getting someone else to assemble it?

If ur not doing it urself, first thing is to find a good builder who u can trust, and talk it out with them. Ask what they know, and have done in the past. Then you can move onto more specific questions

Save money and use a JUN item, cheap insurance in the long run.

Pleas use the search function mate.

Also read the sticky thread, Forced Induction Guide.

There are lots of things already covered in 10+ page threads with more information that you'll ever need.

Oil control, bottom ends, top ends etc have all been covered quite extensively in the past, so asking them again really doesnt do the people justice who took the time to post detailed information before

[Turbz_13]

my car is at a work shop but the are concerned about the oil control and think that i will drop another bottom end. the are a very repitable performance shop and ask me to do a lil researsh into a few things to help me make up my mine as the are flat out.

yeah i have read sydney kids forum on oil control.

there are things i would like to know.

i have been told that there is almost a 50/50 split with people using N1 oil pumps saying the they work or fail, can someone help with this?

will the early model r32 gtr cranks still leqave witness marks on the n1 pump if they have been collared?? or will it be a better idea to get an r33 gtr cranks if possible?

All your questions have been covered.

I dont have time to search for you right now, but i can assure you they are here on the forum
