I'm Currently at the finally at the stage of puttin my motor together and was just wantin some help for the guru's out there... i'm buildin a serious rb25 in my s13, below is everything i have just wonderin if i haven't bought something that i need

Head

Tomei soild lifters, type B valves, Pro 10.25mm cams, cam gears, valve stems, arp head studs, twin spray power enteprise 800cc inj & timming belt, trust rail, sard type rj reg, custom plenum 80mm throttle

Fuel

2x 044 bosch pumps runnin 1/2 lines with 5L surge tank

Block

tomei h beam rods, main studs, oil pump & Bearings, cp pistons, ross Harmonic Balancer, new crank collar, n1 water pump

HKS T51R SPL BB, 60mm gt2 Gate and custom manifold & Exhaust

upgraded power steering pump, oil cooler, fmic, haltech ecu, tensioner bearing

Drive

orc twin plate clutch and os giken strenghtened box, gtr front brakes and gtr diff all braided lines, coilovers and adjustable arms and rods

So far i know the basics on how to build the motor... like once the block gets back from gettin balanced and stuff back i'll know the compression and what head gasket to get. obvioulsy check all the clearances and stuff when i'm puttin the bottom end back together. The head i will get the engineering place to put back together for me so they can set the shims for the lifters.

Does anyone know if there are any aftermarket valves you can get or will the standard ones handle the power and if the standard exhaust valve retainers can be used again(or rebuy standard ones) because tomei only give the intake side retainers with the new springs.

Any help would be greatly appreciated...

Well I know nothing about after-market valves and such but I have access to Nissan FAST parts lookup software... so I can lookup part numbers if that helps at all...

Just need the model year or vin or chassis number of the car the engine is from... otheriwise I can guess based on the year... it appears from a quick survey that exhaust valves are the same for most early RB25DE and RB25DET... would differ for the NEO heads.

      R32 GT-R: 4WD Light Turns On After Bumps – Code 19 (ETS Motor) But No Issues Found

      Look for broken wire or bad connector at the motor. Might not be it, but is worth starting there, as it is easy.

      R32 GT-R: 4WD Light Turns On After Bumps – Code 19 (ETS Motor) But No Issues Found

      By Bireley_32 · Posted

      Hi everyone, I’m having an issue with my R32 GT-R. Sometimes, when the car goes over a bump or experiences some vibration, the 4WD warning light comes on the dashboard. When I check the code from the control unit in the trunk, it shows Code 19 – ETS Motor. However, everything seems to be working fine — if I turn off the engine and restart the car, the light goes away and everything functions normally. Has anyone experienced this before? Where should I start troubleshooting this issue? Thanks in advance!

      I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...
