  • Best services for increasing integrity of a VG33E crank?

    Whaddup ya'll,

    I know their's a plehtora of debate on this subject like most anything in engine building.

    I'm curious what people here and abroad have done to increase the strength of the cast VG cranks? If the Nissan racers broke their cast crank pushing like 950whp before Cyro treating was popular, I wonder what the cast crank could handle after being cryogenically treated? Their's so many cryo treaters now that said service is VERY affordable to the working man!

    Also, Doesn't Nissan shot-peen all of their rods& cranks whether forged or cast?

    I know knife edging has been popular forever to decrease rotational mass but I don't know if I'd wanna do it to my cast crank?

    I've decided to sell my Jun rods and Crank and just build an insane VG34ET with the stock crank and Carrillo H-beam rods with carr bolts(brc pistons of course with 8.5-1 for serious boost). Their's guys making incredible streetable HP& Torque with the 3.4L VG with little or no lag so I'll just stick with my original intent of a Single turbo setup.

    For now my stock VG33E is almost ready to power my S14! Can't freaking wait for my baby to come and then to open up the S14 on the freway with a Turbo VG with the 9-1 compression ratio.

    Any input is appreciated and welcome!

    They usualy knife edge to reduce windage. not to reduce weight, that just happens to be a plus. but if you knife edge you also have to pull weight out of the rods or it will be unbalanced. Well, I guess it depends on how much they take out to knige edge it. either way it will have to be balanced afterwards. even if you dont knife edge it, get it balanced.

    Are you planning on making more than 950whp? if so I would do anything I could to increase the strength of my crank(cryo treating and what not) but anything less than that, why? get it magnafluxed and measured to be sure that it is in good shape to start and be done(other than balancing).

      well i know d&a don`t get a lot of love around here but,

      in a conversation wit him one time he was saying that the 33 blocks wern`t standing up to alot of boost. said that due to the over boring the cyl walls were a little too thin and were cracking. assuming this is true, and the 3.4 blocks are bored just a little more, that would make me a little anxious to boost much. anybody have any input to this?

        I saw crower sells a stroker kit for the 4.8L nissan patrol making it 5.1-ish, it's a dohc inline 6

        a stroker gives you more burn time and therefore torque, but more torque needs less boost, and stroked engines produce more but lower velocity exhaust.. which might behave differently in building boost

        *edit* the dodge 2.5L is apparently better for turboing than the almost identical 2.2 for the spool time

          Well, if that were true, I can't see why Escort would risk
          thier reputation building and selling vg34et.

            VG36ET. just out of curiosity, how were you going to get a VG33 to 3.6 liters? Just boring?

              Hey bro,

              Even if you could overbore that engine all the way to 3.6L, I sure as hell wouldn't wanna run boost on it. I was planning on a slighty overbored VG33E for a VG34E, then the Jun stroker crank I have giving me @ least 3.6L or more displacement.

              AutoworkZ - You are aware that the VG33 block is thicker then the VG30 block? Their's guys making serious power on VG33 blocks and VG34's. I dunno, maybe in the long run the VG30E block with just a standard .020 overbore to remove the lip and add forged pistons is the way to go. Maybe the block itself needs to be cryo treated.

              THey have equipment that can measure the blocks integrity or lack their of to c if it can handle serious boost after boring. I know JWT and others use that kind of equipment but I dunno what it's called.

              I know the stock Nissan copper gaskets can hold 30lbs of boost so 25lbs every run should be easy.

              As for Escort racing, they seem to be top shelf. I'd like to hear their experiemtn and two cents on the VG33E block with the over bore for the VG34E.

              As for Cryo treating in general, IMVHO it's cheap insurance from what I've seen with others results. If a cryo treated cast crank is much stronger then the block in the long run then it would surely be a waste of money.

                  The VG33 can handle plenty of power. I know a guy who knows a guy who knows a guy who knows a guy who knows a guy that runs at least 750whp.

                  OK no really I do know a guy that makes 750 to the wheels on a vg33.

                      Hey crazed, that would be awesome bro. PLEASE DO.

                      I guess I could measure the block to on my Pathfinder VG30E and compare it to the VG33E's I'm building/swaping.

                      Satan - Yeah, I know a guy that know's some girls that where checking out my girl with some other guys. Seriously bro. 750WHP would be an awesome goal for me if the block can hold it long term.

                        You're joking, right bro? Cause i mean...bro, you aint shiftin' like you should, bro! You neva gonna beat me with dreams like that, bro. Bro!

                        If that's not thick enough for you "bro", then there is no hope.

                        And no, i was not refering to your post about mitsubishis

                              You know the vg30 can be bored like crazy. I bored mine 2mm over, stepping it up to 3098cc. Also, i have heard of japanese people boring to over 4mm with no problems making it almost the same as a vg33. Block for block, the vg30 is just as strong as the vg33, if not stronger.
