Basic Rb26 Rebuild

[32vspecII]

hiyall

a friends rb26 died , a valve hit a piston or something . hes rebuilding it . head has already been completed but bottom end is still apart . its going to have forged pistons and nothing else .

what as a minumum is a good idea to do to the engine now while its apart . its not going to be a HP monster just things that should be upgraded now as you might as well while its being built anyway

i suggested n1 oilpump

metal head gasket to lower the cr a little bit ?

any suggestions welcomed

thanks

ACL race bearings.Extend oil pump drive if its an early crank.ARP rod bolts.Use Tomei head gasket set as it has all metal gaskets inc intake and the oil ristrictor for the block.

[blk180]

Larger sump or baffles

[32vspecII]

this is getting expensive........

[N I B]

No

[32vspecII]

how much roughly for bearings and rod bolts ?

what is involved in extending the oil pump drive ?

oh and what gasket kit ,bore and thickness ? would the smallest 1mm one drop the cr and how much ?

If your mates valve hit a piston, it isnt going to be a cheap rebuild, sorry.

[R31Nismoid]

Larger sump or baffles

Why?

What deems that a requirement?

arkon - whats the use of the car?

I suspect just usual street duties?

[32vspecII]

just usual street duties as I said , occasional amature drag , track work nothing serious

its not going to be a high hp motor , it will probably get a pair of 2860-5s like i have for my r33 . its probably about 350rwkw max but it would be good to get some reliability and strength

its basically a dead rb26 thats getting rebuilt to fix it rather than performance , but I thought you might as well do some stuff while your there to fix factory deficiencies more than anything

Its says any suggestions welcome you do what you want with your engine but tomei baffles dont cost much and can help keep oil around the pick up. I only have 2530s and have larger sump and baffles. Do as you please that is one of my "suggestions" i didnt say it was a requirement.

PS i also used ACL race bearings and need the JUN or copy Crank collar for N1 oil pump if its a R32 crank.

That's a bit of a contradiction. You said not high hp, then 350rwkw? 350rwkw is not cheap.

Perhaps you'd better let us know what his maximum budget is, then we can let him knnow what he can AFFORD for the price, rather than what is NICE since the engine is open?

wow! just 350rwkw!?

So you want a 500HP road car and its not high HP!? You'd be sinking some serious $$ into this car to keep it running with that much power.

[32vspecII]

am incorrect in thinking a pair of 2860r -5s with cams would be about 330-350rwkw . probably closer to 330 i guess

and there seems to be a lot of unopened rb26s doing that in the rb26 turbo upgrade thread

by not high hp im thinking more 1000hp twin to4z or something along those lines

Without dragging this off topic could someone be kind enough to list every single part (and quantity of each) required for a bottom end RB26. Their are plenty of us that drive these cars but don't know the absolute minute technical jargon and would value this information which im sure would help the OP in his request of info too.
