Thats odd, what pistons are they?

I will be doing first start up of my fresh SR in a couple of weeks and am concerned about getting something wrong.

I am under the impression that idling the thing too long before getting into the run in to cause this sort of issue. Was this the case for you?

thanks for the confirmation..so then i just need to change to forged aftermarket connecting rods as the rod shoulder looks lower than stock rods..earlier i think that stock rod gonna fit at first and after dummy fit,it wont..btw, nice project u got there.. :)

  • 5 months later...

So I think my patience has finally ran out and I've broken the back of the bank account for the final time.....

So I've decided to get EOI to part out everything I can salvage from the engine.

If you or you know anyone who could be interested in any of the following let me know - I'm thinking i'll cut my losses and stick a bog stock 26 in an move on....

The List:

Rb20DET Tomei 272 9.25mm In+Ex Cams $600

RB20DET Tomei Solid Lifters $600

RB20DET Tomei Valve Springs $350

RB20/26 HKS In+Ex Cam Gears $250
Spitfire Coil Packs $200

RB20 HyperTune Custom front facing plenum * Work of Art*
Hypertune 90mm Throttle Body to Suite above

Prefer to sell as a pair $2000

SARD 650CC Injectors $400

RB26 SARD Fuel Rail $200

RB25 Top Mount T3 Manifold

Kinugawa To4z/Gt35R * I think Combo* Turbo
TiAL 38mm WasteGate

Custom 4" > 3" Front Pipe to Suite above combo

Kit $1300

Rb26 Crank Good Condition $800

Ross Balancer - Need to check if this is for a rb26 or rb20 $300

Eagle Rb26 Rods *Little end will need bushes replaced as they were re-sized to suite pistons - Roughly $4 each from ACL* $450

Nitto High Flow Oil Pump $800

ARP Rb20/25 Head Studs (Brand New In Box) $200
ACL Rb26 big end bearings +0.001 (Brand New In Box) $55

All Prices are neg. however I'd like to get the most back out of this 6 year ordeal. I Can provide pictures for serious buyers if requested. Condition on all items is excellent and most have only seen less than 5 hours of engine work.

Cheers.

What's hard about it? What specifically do you want done?

I cannot see a great difficulty in assembling one engine.. I would be prepared to do it.

Unless you want stuff CC'd and full micrometer blueprint job. I don't see the need if you were happy to sell all at loss and whack in a stock motor. You may as well assemble and use the thing.

yea i want to know the CR and measured and get recommendations on why the piston skirts have worn so much in such a short period and then recommend a piston.

the last two builds didnt last more than a few hours on the syno and these people knew what they were doing....

if i can get away with it id love to complete it and use ca18 pistons but i dont know if they will do the job.

The skirts would be worn due to bad piston to bore clearance, nothing else. It can't be anything else. It's probably a similar reason why there has been blow by issues (bad machine work).

When I built my motor and took it to be tuned I was given praise about how good it was. When I gloated that I built it myself I was given a rude wake-up call that the machine work was where the fine art is, and not so much the assembly.

That said, it sounds like you had machine work issues on both your failed builds and you should source your own machine work. Then you can sit down and assemble the thing slowly and gap your rings per how you would like them to be.

    • Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.
    • How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP
    • I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use
    • I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.
    • You are all good then, I didn't realise the port was in a part you can (have!) remove. Just pull the broken part out, clean it and the threads should be fine. Yes, the whole point about remote mounting is it takes almost all of the vibration out via the flexible hose. You just need a convenient chassis point and a cable tie or 3.
