Hi all,

Recently moved to Penrith & all of a sudden im getting the about to spin a big end bearing tapping noise... So wats my options? Im on a fairly limited budget & not really looking for big horsepower. Ive already got N1 turbos, power FC and injectors on the dying engine i can use (just did the timing belt too...) I would be happy with a low km second hand Rb26 but for 4-5grand would i be better off rebuilding mine?? Please help, any advise is much appreciated! Oh btw its a 93 R32 GTR.

Cheers

Nick

Just put some new bearings and rings in the bottom end and have everything cleaned up and that should last u for quiet a while. I wouldnt bother changing the rods and pistons if you are on a limited budget as i there would be no point if you are happy with the way it is now.

if your not planning on making decent power then just do a standard rebuild and you'll have a nice fresh motor, however if you do have a grand or so spare some forged pistons wouldnt go astray, wouldnt worry about the rods unless you want to make big power and rev it

clean block, measure bores and crank, light hone or rebore if needed, grind/ linish crank if needed, minimum parts rings & bearings, maybe new pistons as well

check between water jackets and head bolt holes on blocks as the rb motors like to crack there alot

vacuum test, preussure test, change valve stem seals grind head probably then the rest would be labour

a 2nd hand motor you may not have or get told the history and it may not be far from ending up in the same condition its cheaper but its a gamble

ok before you do all this exxy stuff ... since I have lifter noise (tapping) for a min or 2 during cold starts, I've read a lot about possible causes and similar noises and one of them was to do with timing belt not being on tight enough. Since you mentioned that you just changed the timing belt maybe check this out .. could be something as simple as that.

Also check the exhaust manfold studs/gasket - apparently if the gasket is leaking or any of the studs have snapped (common) you will hear a tapping noise until engine warms up.

Then again, maybe it's what you said and I'm just full of it ... but worth a look anyway as you said you're on a budget.

do a standard rebuild. you never know what you're buying when you get a 2nd hand motor. it should cost you around the 4k mark to do a standard rebuild at a workshop. at the same time you can put in the required restrictors for the oil supply to the head.

make sure the following things are done at least:

- rods, pistons and crank are balanced (approx 160-180)

- head serviced (~500) and machined (~60)

- metal head gasket (~400-500)

- oil feed restrictors to the head ($30 + fitting.. they just press in so it shouldnt be a drama)

- tensioner and idler studs replaced. (cheap)

- water pump (~80)

- front (crank) and rear main seals replaced. (cheap)

- as you've got a 93 r32 GTR (as in your profile thingo) you will have a R33 crank so you wont need to get the crank collar done, but its always worth checking just in case the motor has been replaced by an older one at some stage. if you do need to get it done it will be around $300 supplied and fitted.

Above all, get opinions on the workshop you decide to take it to. i wish i did.

Standard rebuild on the bottom end only if it really needs it(rings-bearings), If you buy a second hand motor it may not last that long, I mean how many RB,s are not thrashed, might cost a little more but for the peice of mind I would go with a rebuild.

Your pistons-rods and other bolt-ons should be fine, did the water pump get replaced with the timing belt?

Are you sure its the bottom end ??????

    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny 
    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
