yeah i was just thinking that.. i remember hearing tensionsers are f**k all any ways.. when i order thermostat head gasket water pump and now two tensioners was their somthing i red in this thread about series one rb25 oil pump works fine without the collar.. as its the same length on the series one rb25 crank??? any confirmation?

Engine/Car: RB20 A31 cefiro Type of failure: broken ringlands on piston #3 and #1... possible valve seals on god knows what pistons.. oil mania Factors influencing the failure: holding a 3rd gear slide at mallala with the full face helmet and experiencing my first taste of detonation State of tune of the engine: 3 inch turbo to tip zorst no cat no mufflers, pod, r34 smic, bleed valve set at 13psi. Suspension and tyres: full tein s13 coil overs, random treads Oil used and service interval: mobil 1 10w50 i think General comments: warmish day at mallala.. bit to excited with my first time on the track.. bets fun of my life sliding while not worrying about police.. now that motor is f**ked.. 70% threw rb25/30 build yeeooww

alright sweet..... hmmmm should be okay to just use the stock rb30 tensioner and the tensioner off my rb20 aswell.... sweeet as chhheeeers for all the help

oh okay rekon i go with two tensioners.... its best to determen where to drill the hole for the second one after you have your timing belt? so to get the right tension kinda thing?? salesman and a half you are dahtone.. haha im already in debt to ya.. does crank need to be removed to fit the crank collar??

what about leaving the stock rb30 oil pump and not running any restrictors or anything???? its my understanding that to fit the crank collar the crank has to be removed from the block and fitted professionally, is this correct???? anyone got a spare rb25 idler sitting around?? haha

haha yep ripco for sure ay... spewing. as their is also a sprints in my town too... oh well repco is just a pushy ride away and already paid for... where abouts can ya purchase the head oil restritors?? yeoooowww

what about leaving the stock rb30 oil pump and not running any restrictors or anything???? i planned on just using a stock nissan rb30 head gasket... its my understanding that to fit the crank collar the crank has to be removed from the block and fitted professionally, is this correct???? cheeers ps just ordered my dayco timing belt threw repco, cost me $60 cuz they had to order it.. what has anyone paid for a genuine rb25 idler???

oh reallly..... maybe not such a good idea with the restrictors aswell as the 30et pump?? wat pump would you suggest going with... my other thought was a rb25det pump.... was not sure if you needed the crank collar if you went with the series one oil pump??? cheeeers

its just an idea at this stage as my motor seems rather heallthy... the factory hone marks are still looking good. i was thinking of putting rb30et oil pump and that being the only real change to the bottom end.. will be chucking in head oil restrictors also... im havingtrouble finding any place tha can suply the tomei press fit oil restrictors... what kinda of power figures are your mates cars running??? im running a hks T04e turbo.. i cant imagine it flowing enough to get anything over 270rwkw.. ill be happy to get over 200 at the wheels.. i have just brought dahtone racing (from this forum) head from his 32 which has been ported and running gtr valve springs.. all i would be buying would be genuin head gasket a idler and a genuine water pump and thermostat....

has any one tried their luck with grabbing their series 2 motor from a wreckers then slappping the head on with new head gasket>? like not touching the rings or bearings in the bottom end???

and how much was it for the genuine nissan bearings??? and how much just for the acl bearing kit?

okay and thats with stock pistons and rings?? what engine builder is it at roughly were is he located as im from just out of adelaide?? cheeers mate tom
