    Neo/Hitachi CAS help needed!

    in RB Series - R31, R32, R33, R34 (1986-2002)

    Posted

    So my mate with an r33 Coupe RWD Gtst rb25det series 2  has had cracked ringlands and pulled the motor. 

    Instead of rebuilding his motor he bought my AWD Series 3 rb25det block and head. (I Have no clue what it came out from but its a low mile virgin in excellent condition)

    Now when putting everything back together and "converting" it to rwd he realized that his series 2 CAS will not mate to cam gear inside the head.

    SO.... what do we do:

    1) Wire the series 3 NEO/plastic CAS to his OEM series 2 harness?  (can this even work?)
    2) Use his original head? (beat the F*ck up from years of red line and drifting so he doesnt really wanna do it)

    open to any suggestions or advice. we are kinda stuck on this and need some help.

    He is using the Apexi Power FC (idk if this worth mentioning)

     

    What is this?

    So this came off of the passenger foot well, up by the firewall and its from r33 gtst. It had a rattle in it and so it has been opened up to check what wrong. We dont know what it is and we cant test out anything as the motor is out and being rebuilt. Everything was “fine” from the last drive with the car being pullin the motor

    Can you spot the differences and what do they mean

    This is the first time I ever seen a post about this.

    I expirenced this before and was super confused because everyone and everywhere claims that all the blocks are the same between s1,s2,s3, Neo turbo and non-turbo.... but this claim is not true and your pics prove it, especially on the deck. (never seen that Before) 

    But here are MY personal findings of other differences... When  building my r34. I had a series 3 rb25DET laying around and thought it would be better to throw it in the R34 instead of turbo'ing the DE N/A Neo but when I pulled the engine out I soon realized that the lower 2 holes on the block by the bellhousing ( as seen in your pic) does not exist on the turbo s3 block and What this meant for me was that the 5-speed Small box or rb20det/rb25de gearbox that the car came with will NOT bolt up to the turbo block completely and in fact will be missing four bolts from the trans to the block. these additional four bolt holes on the n/a neo block would hold 2 long brackets that connected to block to the trans as seen below here in the pic.See the source image

    Engine Rebuild Question....

    Hello,
    i am building a 350z drift missile with a florida imported Aristo 2jz GTE VVTI


    My partner and I are trying to make it as "budget friendly" as possible while still retaining reliability and decent performance. We have a build list of new parts such as top mount manifold, turbo, gaskets, studs, oil pump, water pump etc etc. 


    So here is my question.... while the engine is out, we were planning on doing all the rotating assembly bearings and we were wondering If it would make sense that we pull the pistons out, clean it up, then replace all rings, then finally hone the cylinder bores with a honing pad/stone ourselves. 

    I know that you shouldnt trouble the rings and bores if you are making good compression but if the engine is out... wouldnt it be a good idea? Is this too risky? i have seen a few people who have just got a hone and new rings and reused the stock rods and pistons but i would like to know if honing is something you can do your self and still achieve good results.

    You need the big box tailshaft from a r34 gtt as splines are different. 

    Sorry but can you explain a lil more? my car is the 1998 ER34 25GT COUPE non hicas... so what you are saying is that i would need the front half of the r33 gtst's drive shaft as the spline that goes into the gearbox is different? Would this also mean that i may need to shorten or modify the overall length? Thanks for the reply by the way 

    R33 big box on R34 GT?

    I got a pretty good question for y'all that i cant find an answer to no where..... 
    In the event that my r34's 25De+T small box may one day give up with the abuse of being boosted and drifted, What would be involved with changing the small box to the R33 big box?
    My Main concern would be driveshaft compatibility, i do not think that my current stock drive shaft will work. Can anyone please shed some light on this, anyone ever done this in here? Any ideas or advice is welcomed.
    Thank you.

    AEM Water Meth Kit on Rb25neo Question

    in RB Series - R31, R32, R33, R34 (1986-2002)

    Hello everyone,
    Please dont murder me but Can you run a water meth kit on a stock r34 GTT ECU?
    I have been considering doing this for the reduced chances of detonation, lower intake temps, and the cleaner combustion. 
    Some one told me that you need to tune ecu's fuel mapping in order to gain the power benefits but he also mentioned that even with out a tune its still beneficial to run and cant do no harm. 
    Anyone have a similar experience? is it safe?
