ok guys its time to put your thinking caps on as i am in a lil prediciment at the moment and it is time to freshen up the old RB and seeing i have just put Trust T517z's and tomie poncams and a few other lil bits i feel that the bottom end is probably in need of some TLC. Just a note this is a 94model R32 GTR with supposed 103,000kms on the clock.

so here are the options and please note that both are going to cost similar amounts but i am aiming for reliability and performance (somthing that is very rare in modified cars).

Opton 1: Full rebulid on current motor meaning CP forged Pistons and ring set, R.E.V I-Beam Conrods, TOMEI metal manifold gasket kit, HI OCTANE RACING rocket cover baffles, NISSAN engine gasket kit, TOMEI sump baffle, Nissan N1 Oil Pump, ARP 2000 Series Head Bolts, RB26 Cam Cap Studs Set and an R33 crankshaft. All will be balanced and blueprinted and some sort of strenthening process applied (cant remeber what its called somthing about freezing it all then zaping it hot again. cant remeber.)

Option 2: Buy brand new N1 motor and put my turbos, cams and a new sump baffle in.

well there you have it all feed back will be taken on the chin. :O

thanks

Absolutely, and you can throw all the tricks in the motor when you rebuild it, like oil control and good balancing, checking clearances etc etc. 12k is a lot for a long motor that you would have to open up to get the same level of reliability as a rebuilt one

anything actually wrong with ur motor? 103kms aint too much. RB26 r a pretty damn strong machine. make any funny noises? and did u just recently do ur 100,000kms service?

he is on the limit with the turbos he has on there :(

its a matter of time, especially if he gets on the track :D

hmm ok thanks guys any more input? any one else?

rebuild,rebuild,rebuild. cant beat a nice "weatherd" block.

besides n1 engines arnt all the bees knees anyway. apart from the water and oil pump. the pistons are still cast.

sure the block is better, but are you aiming for 1000hp??

just do a rebuild. youl have a much stronger base. with all the fruit and some change to blow at the casino :lol:

n00b of the day question please:

What is the difference between long and short motor? Is a short motor just the block and the head? If you saw a long motor for sale what would expect to be buying? Includes loom/airbox/etc.?

im 99% sure short motor is just the bottom end complete, and long is head and bottom end without accessories (no manifolds, etc)

make sure you get someone who can build engines and who has a rep for rb motors. and someone who knows them inside and out.

i beleive someone mentioned race pace.... there is a wonderful start. hit them up with the telephone call and see how it goes.

but i'd also go with the full rebuild. you will have alot more control over what goes into it and the finished product.

      Starter motor replacment teeth count.

      By oHBoy. · Posted

      I had 3 counts over the last couple of weeks once where i got stranded at a jdm paint yard booking in some work. 2nd time was moving the car into the drive way for the inspection and the 3rd was during the inspection for the co2 leak test. Fix: 1st, car off for a hour and half disconnected battery 10mins 4th try car started 2nd, 5th try started 3rd, countless time starting disconnected battery dude was under the hood listening to the starting sequence fuel pump ect.

      This. As for your options - I suggest remote mounting the Nissan sensor further away on a length of steel tube. That tube to have a loop in it to handle vibration, etc etc. You will need to either put a tee and a bleed fitting near the sensor, or crack the fitting at the sensor to bleed it full of oil when you first set it up, otherwise you won't get the line filled. But this is a small problem. Just needs enough access to get it done.

      J50 clock date suddenly reset to January 1

      By suko · Posted

      The time is always correct. Only the date is wrong. It currently thinks it is January 19. Tomorrow it will say it is January 20. The date and time are ( should be ! ) retrieved from the GPS navigation system.

      Buy yourself a set of easy outs. See if they will get a good bite in and unthread it.   Very very lucky the whole sender didn't let go while on the track and cost you a motor!

      Well GTSBoy, prepare yourself further. I did a track day with 1/2 a day prep on Friday, inpromptu. The good news is that I got home, and didn't drive the car into a wall. Everything seemed mostly okay. The car was even a little faster than it was last time. I also got to get some good datalog data too. I also noticed a tiny bit of knock which was (luckily?) recorded. All I know is the knock sensors got recalibrated.... and are notorious for false knock. So I don't know if they are too sensitive, not sensitive enough... or some other third option. But I reduced timing anyway. It wasn't every pull through the session either. Think along the lines of -1 degree of timing for say, three instances while at the top of 4th in a 20 minute all-hot-lap session. Unfortunately at the end of session 2... I noticed a little oil. I borrowed some jack stands and a jack and took a look under there, but as is often the case, messing around with it kinda half cleaned it up, it was not conclusive where it was coming from. I decided to give it another go and see how it was. The amount of oil was maybe one/two small drops. I did another 20 minute session and car went well, and I was just starting to get into it and not be terrified of driving on track. I pulled over and checked in the pits and saw this: This is where I called it, packed up and went home as I live ~20 min from the track with a VERY VERY CLOSE EYE on Oil Pressure on the way home. The volume wasn't much but you never know. I checked it today when I had my own space/tools/time to find out what was going on, wanted to clean it up, run the car and see if any of the fittings from around the oil filter were causing it. I have like.. 5 fittings there, so I suspected one was (hopefully?) the culprit. It became immediately apparent as soon as I looked around more closely. 795d266d-a034-4b8c-89c9-d83860f5d00a.mp4       This is the R34 GTT oil sender connected via an adapter to an oil cooler block I have installed which runs AN lines to my cooler (and back). There's also an oil temp sensor on top.  Just after that video, I attempted to unthread the sensor to see if it's loose/worn and it disintegrated in my hand. So yes. I am glad I noticed that oil because it would appear that complete and utter catastrophic engine failure was about 1 second of engine runtime away. I did try to drill the fitting out, and only succeeded in drilling the middle hole much larger and now there's a... smooth hole in there with what looks like a damn sleeve still incredibly tight in there. Not really sure how to proceed from here. My options: 1) Find someone who can remove the stuck fitting, and use a steel adapter so it won't fatigue? (Female BSPT for the R34 sender to 1/8NPT male - HARD to find). IF it isn't possible to remove - Buy a new block ($320) and have someone tap a new 1/8NPT in the top of it ($????) and hope the steel adapter works better. 2) Buy a new block and give up on the OEM pressure sender for the dash entirely, and use the supplied 1/8 NPT for the oil temp sender. Having the oil pressure read 0 in the dash with the warning lamp will give me a lot of anxiety driving around. I do have the actual GM sensor/sender working, but it needs OBD2 as a gauge. If I'm datalogging I don't actually have a readout of what the gauge is currently displaying. 3) Other? Find a new location for the OEM sender? Though I don't know of anywhere that will work. I also don't know if a steel adapter is actually functionally smart here. It's clearly leveraged itself through vibration of the motor and snapped in half. This doesn't seem like a setup a smart person would replicate given the weight of the OEM sender. Still pretty happy being lucky for once and seeing this at the absolute last moment before bye bye motor in a big way, even if an adapter is apparently 6 weeks+ delivery and I have no way to free the current stuck/potentially destroyed threads in the current oil block.
