Thats definitely no good.

Does SK run a dry sump in the RB30DET race cars? I remember he had mention of on that was up around 650bhp.

sorry to hear that R33 racer, like everyone else i'm keen to know what happened. i have a new N1 sitting on the bench ready to bolt on; having read SKs post in the 'N1 killed my motor' thread and knowing Cubes has 45k km on his made me breathe a little easier but still i'm concerned. AFAIK SK is running a wet sump on the engine he's building atm, with an N1 pump.

On the motors I have built I have always undone the backing plate and put allen key bolts in it with the high grade locktite, the backing plate coming loose is as big a problem as the gear cracking, which only seems to happen on N1 pumps. There is a thread on it in the general section but after that a friend of mine who works for the CSIRO did a few quick tests and as per suspesions the N! gear is a harder metal but probably more brittle, this could be a heat treatment issues or a number of other variables. I will be sticking with R34 standard pumps from now on!!!

R33_racer..

On a more cheerful note..

This new motor. Anything you would have done different?

Higher static comp? Lower?

Interestingly I remember the Gibson motor sport GTR ran quite a high static comp. 9-9.5:1 I think it was. Can't remember exactly. :thumbsup:

Sorry to hear the bad news R33_racer

Do you guys recomend pulling the back plate of a n1 pump and locktite on the bolts im in the process of building at the moment so what ever you guys can recomend me doing so i dont blow it up will help lol

r33, seeing as u prolly dont have air-con, why not run an extenal pump? can be done for near the same money as a JUN pump, and u won't have the dramas of an 'internal' pump. also if i remember correctly, u have an ATI balancer, so u can just buy an 'adapter' that bolts onto the dampner and the belt for the pump fits up nice and easily :thumbsup:

yeah i was talking to millennium msport today & at autosalon about my set-up, and for the cost involved, it'd be worthwhile spending the little extra and go external pump. mark jackobson runs the moroso u talk about daniel, so it should more than do the job :P

also, apparantly the peterson pump is slightly better than the moroso (it has a stage 1 in it, scavenging?) but millennium said they've never heard any problems with the moroso

yeh were considering all these options. But first thing is to strip it down and find out exactly what it was thats done it. Could be end of week by that time cause my rb25 is still on the engine stand taking up space.

Has anyone looked into/used one of these?

Apparently replacement internals for the N1 pump explicitly to strengthen it.

Would this be best of both worlds? ie not a High Volume pump - so no problems with too much oil being pumped up to the head, and fixes the arguable strength of the N1 Pump...

jebus! @ $520 is it really worth it?

Well...... ask R33_racer ? :P

I guess if a N1 pump is circa $500 and the Reimax internals is similar - then you have a $1000pump all up - which is still on the cheaper side of things like Nismo, JUN and Tomei - but without the 'problems' of a high volume pump?

hrmm yeah good point...i took a pic of one of the millennium skylines they've just built, and they ran 2 feeds from the front of the head into the front of the sump (to alleviate crank case pressure)

Edit - tell a lie, i took a photo of the car, but not of the lines...

I just dropped my head off to get all tested cleaned up and the reconditioner claims $170 odd just for the valve stem seals!!!

Is this correct? or am i getting ripped blind?

last time i did a head on an rb30e the complete vrs kit was $180!

was goping to buy exhuast inlet sepperatly off this site and get engineer to suplly cam seal and valve stem seals, thought it would be cheaper see'ing as no VRS kit comes with cometic head gaskit.

Buy the Geneuine VRS kit that come with cam seals, headgasket (that u can sell off), rocker cover gaskets, inlet/exh gaskets, plenum gaskets, valve stem seals and a few other little bits.

They are worth ~$280 from Nissan.

I priced up a set of valve stem seals from nissan for $330. :S

    • Sounds more like what Brad said, that it's mainly transfer. What pad bed in procedure did you use, and did you replace/machine the rotors, or just swap pads?
    • The stutter is almost entirely in the pedal. I don't feel the brakes release and reapply as you would with ABS engaging but the pedal feels that way, without the brakes releasing. It only lasts for less than a second and the pedal is fine again. It's hard to explain, sorry.  I'll get under this weekend and just double check everything is tight. Fluid is at max where I left it.
    • What bedding in procedure did you use?   When you say stutter, what exactly do you mean? Like it feels like someone letting go of the brakes momentarily and regrabbing them again to get you to stop? Re-reading your post, and that is what it kind of makes me think you're explaining, like theres a little bit of a jolt, likely just as you're reaching a stop. I've only had this issue once. And if its caused by what caused mine, you will want to get the car up on stands again and check it over. Mine was a case of a caliper mounting bolt coming out and letting the caliper rotate on the other remaining bolt and gave play in a wheel as it came to a stop. But not every stop either!
    • Yeop... binned it   This will be a summary will not many pics atm and cbf  Fixed the samsonas - it was totally munched Put a new precision 7675 T4 on with proper split pulse mani Got to Sydney to get to car - drove to canberra to get racecar - drive back to sydney that night Next day all day at Plasmaman putting on new clamps cleaning some things up and adding another large engine oil cooler sitting at the rear above diffuser to keep things cooler Next day - Tuesday - on Dyno - killer wikid awesome pumped out really good numbers - more mid range and on lower boost levels Wednesday - first prac - all day again getting the suspension right - had to borrow front suspension again - out do a lap come in - out do a lap - in - what i had just couldnt handle the load at the more consistent higher speeds - got a lap in at the end of the day that was pretty reasonable  Put it this way that lap wouldve had me in 4th in Pro am for the whole event - with only 700 hp and used tyres Thurs first official prac day - lap out warm up - then entered a hotlap with above setting and 80% effort took corners 1,2,3 and into 4 car felt awesome -  rear came around out of nowhere bang into the wall near front on at whatever 140 kmph Done, over, gone Just one of those how did that happen apparently as all indications show nothing out of the ordinary Got to spend the rest of the time at the event like I hadnt done before - was actually Ok mainly as I had my family and my boy is 9 and got treated like a rockstar Long trip home, lost a trailer wheel in nowhere land, X5 airbag suspension gave up half way across nullabour and rode on bumps stops (its now completely fine) had to do a 19 hr drive day on day 3 as accommodation got screwed up so just had to keep driving till found a town with some Now to reassess - hopefully the motor and other things are OK but yet to be seen too. There is no easy fix there is no i'll just order that part and get it sent - we'll have a talk to people see what can happen and what the go is but at minimum its rebuild from scratch struts forward and alot of time effort and $ should and if I return and if but maybe/ when  I have the cage tied into the front strut towers - if I didnt have that things couldnt been worse you can say its just a front end but if you know what goes into these cars... you'll know what that actually means in reality   Car was very fast. Disappointing we just didnt get to show it Effort doesnt win you races though     Apparently this is motorsport !  
    • Thanks, will do that.  Thankfully they still feel great.
