Main Bearings

[meer_motorsports]

hey guys sad to say this but this is the first time iv been on skylines australia.....i realy should have come earlier but now i am so here we go...

i am currently in the process of rebuilding my rb26 in my r32 GtR the guys at toda really put me in a bad place and now i am in the process of putting their mess back together....

my main problem is the kind of main bearing and connecting rod combination i should use....some say one thing others say another and it all comes to preference with workshops but what i want to know is what others are using and if they have had any problems with them....

i will take any opinions on board and would appreciate the help....

thanks guys

The bearings and rod combo wont mean much if the engines not built right, pick the best known engine builder in your state, don't get sucked in to using some shit talking show pony, and do some good RESEARCH on this one as it will make all the difference in the end, it also depends on your expectations with the engine build and budget, the rest should fall in to place, as far as choice goes ill leave that to others.

When it comes to bearings, I think most Jap tuning companies just resell ACL's bearings

agreed take it to someone who knows thier RB's, not some v8 pro as nearly all the engines ive had come in from that type of shop rattle thier heads off and fill the rocker covers with oil as they know nothiing of restrictors and so forth that these engines require. There are some very good shops in NSW that can set you on the right path.

As for main bearings we run Kings exclusively but the type is not so important but the precision in which the crank is prepared to suit said bearings is crucial. For example ALL our engines are tunnel bored assembled with the bearings then the crank is prepared to achieve the required clearance.

I think you should list what you have (parts wise) and what your apllication and powergoals.

hey thats great guys, thanks for the input i talked to a few tuning shops and my mechanic from is motor racing did not want to endorce acl bearings, once he said no i kinda didnt want to ask why, iv orderd tomei connecting rods now so now im jus looking for bearings.....im trying to get the same kick ass power from the mines r34 gtr...u know the one that still got the 2.6 and as close to factory twins, and still kills other gtr's it competes with...(although not all) thats my expectations though..

Please dont try and build car that drives like the Mines R34, there is so much to that car, very little has to do with it being 2.6L and running smallish twins. It has more to do with the crasy short diff ratios, carbon prop shaft, some 250-300kgs lighter then std...not to mention it has a 6 spd where R32/33s have 5 wider gear ratios...list goes on

I'd recommend using ACL bearings above anything else. They're a proper performance bearing rather than a stock replacement.
