    NA to turbo conversion - questions and answers...

    in Turbo / Supercharger

    Posted

    Is it feasible to install dished turbo pistons in an F54 block and use a P79 head with a turbo exhaust manifold? Or am I better off running the flat tops and lower boost?

     

    Depends on what you want. If response and fuel efficiency are more important than an impressive dyno sheet (especially if only for 'bursts' of power), then I might lean towards a higher CR.

     

     

    ...and even used the NA electronics. I can't tell how satisfied they are with their decisions, or how long the motors have lasted, or knowing know what they do now if they'd do it that way again. Can't find that in the archives.

     

    I know a gentleman, in a stock bodied Z, thats run well beyond 200mph (documented) with something similar to what you describe. He understood what he was doing. I've also done it, although not on that level. Would I do it again? Heck no... its a pain in the backside.

    Today was the first truly trouble free long drive in my car....

    ....and now I know why most folks here stick around. :) I had a grin from ear to ear after the 2nd hour.

     

    Good to hear :cheers: Its the level of challenge that makes the reward so rewarding.

     

    I'm not exactly sure how he did it, but "Mr. Wolf3D" has hooked up visible and audible warnings in case the oil pressue or engine temp goes beyond a certain limit. I think you can also have the engine automatically shut down if you lose oil pressue or the temperature skyrockets

     

    :wink: You're correct, Hugh... those things are pretty straight forward. There's a nearly infinite ability to integrate safety provisions, both invasive and non-invasive. I would caution on shutting the engine down, though. Its easy enough to accomplish, but I can't think of many scenario's that I'd be comfortable with that. However, a 'limp home' mode can be created for similar purposes.

    ahhaha holy ♥♥♥♥ I want one of these!

    and for guys who race or auto x alot. driving a z is fun, but driving a tuned type-r or a nicely swapped and built EG hatch on a autox is so much fun. there is nothing like driving a well tuned dc2 through some sharp down hill turns at any road course with major elevation changes.

     

    Since this is opinion based, I'll toss in my two cents... I've been nearly equally successful in both FWD and RWD... but the fun gods lean in favor of RWD... nothing like four-wheel steering to 'supercharge' adrenaline.

    HybridZ custom suspension design thread

    ...is C4 vette suspension really all that much better then Z car?

     

    Great question! Unfortunately, you'll get all sorts of opinions.

     

    Here's mine... in a word, yes.

     

    First I think there is some importance in distinguishing a C4... there are two varying front suspensions... '84 through '87 and '88 through '96. Within those will be further arguments. Putting those aside...

     

    Its not so much that a C4 is 'all that', but I think its reasonable to consider that there's ~15 years of technology difference (willfully acknowledging that technology is not always advancement).

     

    In summary, the S30's front suspension is high on kingpin & scrub, low on caster, with no appreciable ackerman, and coupled with high unsprung weight. Thats not an insult... just contrary to modern beliefs.

     

    There are a few members here that will argue either side with more savvy than I, but the point remains... The C4 front suspension leans more in the direction of improvement than not.

    Do you realize you brought back a 4 months old thread to ask a question that could have been simply asked by posting a new thread?

     

    I would actually prefer relevant information in relevant threads... even if it goes on for years. I believe the search engine is used to better effect, in that scenario.

     

    And to top it off, here's a link you would have gotten had you searched.

    http://www.zcar.com/forums/read/1/597707/597707#msg-597707

    It was linked in a VB Power Locks thread.

     

    I think its asking a little too much to ask members to search in other forums. While its good advice to dispatch all of your resources, it would become a never ending can of worms, in my opinion.

    L28 ARP main stud torque

    in Nissan L6 Forum

    Again, is this with oil or moly? The spec that I received with my head stud kit gave both numbers, and they were quite a bit different. It sounds like they may have changed their spec, but the 60lb-ft number is closer to the number I had for motor oil.

    Now that I am looking at it, 60lb-ft with moly would be getting pretty close to the yield strength of the stud, according to the spec they supplied with mine.

     

    Tim,

     

    I just opened a new box of ARP head studs and the paperwork specifies 60 with moly lube.

     

     

    main cap? head to block specs is what i need. maybe thats just different terminology but idk lemmie know.

     

    Not different terminology... different part. The main cap is the cast piece that fastens the crankshaft in, and contains the lower bearing half.

     

    Stock head bolt torque spec (done in three stages)... 29 lb/ft, 40 lb/ft, and finally 60. There is a recommended sequence, so either do some searching here or pick up a Haynes manual, FSM, etc, etc.
