Hey all,

RB25DET motor...

If you had $2000-$2500 to spend on Pistons and Rods.. What would you get?

Ive had a look around and asked alot of performance shops.. Ive got an idea of what I want. Ive heard everything from CP, Spool, JE/Nitto, Eagle, Manley, Mahle to ACL..

In your opinion what would be the best combo for the money.

Set up I currently have, is tomei forged rods/pistons, tomei cams/cam gears.. and i've melted/cracked a piston on 1.7bar at 8200rpm. Want to buy rods and pistons.

Thanks,

Matt

2.5k will get you plenty of decent stuff outta the US at the moment.

There are plenty of Rod/Piston Combo's to be had from ebay retailers.

Just make sure they have an actual website/business as well, not just the 'backyarder' style ebay seller.

Although if you cracked/melted a piston mate, that wasn't a fault of the mechanicals...

Yep, understand this. Perfectly. But, it needs to be fixed. Thought about going a 2.8 stroker... but for now just want to get new rods and pistons in the thing, get it running and keep the mrs happy lol.

Can you recommend any parts? people in the states? links maybe?

Because of so many different choices its made it harder to choose.. if that makes sence? is anything brand/part better than the other?

Car did make 510rwhp. before deciding to empty the sump though the catch can breather and blow smoke like ive never seen lol.

Thanks for the quick reply.

Matt

I'd work out why a forged piston melted before deciding which one you want to melt next

510hp is nothing, 1.7 bar is nothing and 8200rpm is nothing

The answer to your question is not which one is going to be best, it's which one you can get the easiest and cheapest. They are all equal and no matter what anyone tells you, they are all going to be perfectly fine in your application. It's not until you start making over 1000 hp that piston choice really matters

for my money given current forex rates i would go with:

tomei rods (had between $1000-$1200 at the moment and very nice)

as the guys said there is lots of good piston options out there. so piston choice is a bit more open.

CP pistons are a fine choice.

or maybe some mahle short skirt pistons if you are that way inclined.

there's other good options too for reasonable money, just do a bit of research on what people are currently using in RBs.

RB20DET rebuild kit?

I posted a link to the 25 kit about 4 posts ago............

Thanks everyone for your input.. its been helpful :)

Ive ordered a set of Manley H-beam rods with ARP2000 rod bolts, .020 over CP pistons (almost got Weisco pistons but figured CP would be the way to go after more reseaching).

Also ordered ARP headstuds.

Now looking into barings. Probably use ACL Race series or maybe Tomei.. havent really decided yet

As for the headgasket im looking at either a Tomei or a Cometic.

Anymore opinions on barings and gaskets??

Will rip the motor out and start stripping it down this weekend, will send the block off to be acid dipped, bored, honed and get all the machine work done.

Hopefully get it back next weekend and start bolting it all back together.

Heres hoping the crank is ok, or i'll get a new crank rather than have it machined and fit oversized barings, i dont like that idea.

Figure while its out i'll fit a Ross Harmonic metal jacket balancer.

Thats about all I can think of for now..

Cheers,

Matt

    • Yes. You will need to get the original boost sensor and wire it in. That is.... if you plan to use a stock ECU - even a Nistuned ECU. The Nissan ECU will not operate correctly without it connected. And yes, it will do annoying stuff like you are experiencing. You will almost certainly be better off with some aftermarket ECU, than trying to hunt down rare sensors.
    • Ok so ABS/TCS is "not" the problem. Yeah i know now about the ABS with Nistune(i told that to the Nistune guy) but iam not 100% why or why i dont have ABS. ABS cube is in the engine (always has been) but i had braked couple of times rly hard and brakes just locked and scream. Does all Skylines have ABS cube? That boost sensor https://www.sau.com.au/forums/topic/367633-wtb-r34-gtt-turbo-pressure-sensor-pics-inside/ Is this it? I need to ask but i have a picture of engine bay and i do not see that (100% is not in that place) If i do not have this the car can do what mine is?(cutting around 4000 rpm) Here is the pic of my engine bay(only one i have) BUT i think i dont have that cuz loom was used from my RB20DE NEO and i know (obviously) that it does not have boost control or any wire to that...) so maybe that is the problem? (i dont know for 100% if that car where the engine is from had that)...but i dont have the loom from that
    • I'm with you here. It's either loom has an issue, OR, injectors are not functioning properly. It could even be they're just constantly dribbling, hence the wet, but not firing.
    • Depending on how long the car sat it is very possible for injectors to be stuck open or closed, I'd get them cleaned and flow tested. Other than that, obviously when the loom changes and the car doesn't start any more....the loom is suspect so some tracing / comparing may be required
    • Harness is for a s1 Rb25det, and it is engine and lower harness.  the old harness had broken off plugs and was in very rough condition/exposed wires and splices etc. it is not able to be put back on the car, I could visually inspect to see if they had rewired any pins on the ecu plug. The fuel pump definitly isn’t turning off it’s an external pump and very loud you can hear it. Will look at the other harness tonight, am also going to pull the fuel rail and watch the injectors spray, will update here with what I find. Pretty sure at this point it has to be something to do with injectors because car will fire up on starting fluid and cas is clicking the Injectors. Fuel pressure is steady 43psi
