So have been on the net a while and i have been looking at different options for long block assemblies.

I have gone into the fast system and pulled this part number for a Nissan short block assembly for my gtr34 Vspec II Nur

10103-AB051

Now i have emailed power house racing about this as well and have not been given a confirmed answer so im posting on here

The engine being sold on powerhouseracing website says its a Nur short block assembly but has a different part number

10103-AA450

So what is the difference between these two, can any one with enough knowledge say what exactly is going on here ?

Which engine represents which model of car, am i right in saying the AA450 engine is from the Gtr32 and Gtr33 series and the AB051 is from the gtr34 engine series ?

Im very confused, to make matters worse the short block assembly from Japan for the AB051 i was quoted is 6000usd

And the AA450 i was also quoted the same price .

But on power house racing website its 4850.00 Usd .

Should i be scared of buying that particular motor ?

Hope you guys can help thankyou.

      Here is a recipe. Sonic blocks till you get one that has a good enough bore. Get a torque plate and block brace, use your choice of fasteners (arp ect) bolt the thing together empty, half fill it and let it cure. Release it when it has, go to a REPUTABLE RB Builder and get the thing line bored/honed and cylinder honed to size, then wash. Once its all clean and dandy, wash and blow it out again. Then again.  Assemble said engine to your desired clearances with oil control mods, gasket to suit desired CR/Squish ect. Attach your extended sump with proper trap door oil baffles and head drain plumbed to sump with a SUMP BREATHER SYSTEM. Build your front diff with a decent LSD, rebuild your transfer case with a few extra plates, more than likely replace your tailshaft centre bearing and tighten up the rear diff. Tune to minimise excessive midrange cylinder pressure (timing unless you like to split bores and rebuild engines) Enjoy your engine, but hate the fact you are now destroying engine mounts, gearboxes, gearbox mounts, diff output flanges and driveshafts, diff mounts, tailshafts and front CV's.   Disclaimer.... Ive never done any of the aforementioned stuff.......

      440s will support well over 400HP on petrol, which is a decent place to be for an RB20. 230+rwkW. Will be a safer bet for idle/low load. 550s would be nice for the extra headroom. I've made the same decision with mine (Neo25). 1000s are probably too big for the Nistuned ECU, so I have some smaller ones.

      Did tie rods. Steering now not "springing" back.

      Appreciate everything guys. I did go ahead and get an alignment... most of my complains are solved. Car is not perfect, but it's good enough. If I notice uneven tire wear or anything I'll just take everything back to stock.  Thanks again!

      They still have not shipped the 550cc injectors as they weren't in stock, so in theory I could ask to get the 440cc ones instead, if those work better in my scenario. They're the same price so really shouldn't be an issue. Unfortunately I am not so knowledgeable in most parts of tuning so I wasn't sure what's best to choose between the two. 440cc ones are the lowest they have (not in stock, but available to buy nonetheless).
