    I seriously doubt that the crank will be the first to let go.

    I'm building something very similar and the guys doing the machining for me said cylinder walls would probably give out before the crank mine is a scat crank, scat h beam rods and Srp pistons he steered me away from a 4 bolt conversion and inclined that putting money saved from 4 bolt conversion would be better spent on a little paw iron block later.
    Low rpm equals greater cylinder pressures

    Honestly just use the standard manifolds It will save a large amount of work they flow well enough to run into the 9s.

    I beat on it like I wanted to kill it & it never died, came apart looking pretty much the same as when I put it together.

    You don't need to turn a turbo motor hard, so you don't need exotic parts/mods - let the boost make the power & tune the thing safe, it'll live no problem.

    mr355t from what i have seen on this site this guy ^^ knows his stuff and worth listening to, does everything from 4 cyl to v8 asp and turbo and everything in between does not claim he is something he is not, no bs from what i can see and gives sound advice that comes from experience and does more delivering than talking up and if you look back far enough you will see he is a professional cylinder head specialist, been in the game for quite some time.....just saying dont always believe the hype

    just my 10c worth

    Yes mate made 800 on 9 psi at 6500 rpm engine makes power to 7000
    There is another one i built recently stock stroke just waiting for the car to be finished aiming for 700 min from that one
    I do a lot of boosted stuff
    Doing one in the new year that will make over a housand

    The 800 is carbed
    The 700 is injected
    The one next year will be carb'd

    it always sucks to see someones pride and joy go bang with forced induction the damage seems to always be greater than with NA
    there was a big dollar 55 that debued at PC just gone he only got two laps in before the fireworks
    this bloke won't be building another one in a hurrey as this one took him three years to save for and get built the engine builder chased him out of his shop

    Seen a stock 5 go 600hp with holset turbos, Stock computer tuned which is still alive and baking tyres e85. Stock with springs.

    Tk is right and so is zok.

    The powercruise, if your pumped is an ass rapping session on cars.
    everyone is bouncing cranks, limiters are giing off. Tryers are frying and of top of that your racing in the process with your mates in the car with alot of ego.


    eg.. we have been entered in sydney for a few years now and the cars a tuff.
    mate finished his camaro show quality and said we will go once more for fun.
    Well the nitrous was connected and a small pill was up for show. Remember car was for show motor was a 500 big block crate motor gm.

    4 hours later we are on the way home.picking up..
    Slicks, laptops,bottle refriller, bigger pills, c16 drums. Spare tyres and every tool under the sun is in the ute.

    We are now heading back ready to take on the world.
    we ended with a torched piston, and a bearing on sunday, we started friday morning.

    point is powercruise is not a cruise session.

    I love holden turbo motors better than an ls1 turbo.
    Has more pride behind it lol

    Default Hyd roller 355 turbo build

    So much emphasis on power cruise killing cars, must have exotic parts etc etc

    Hell I did PCM with my cast piston, 2bolt (no arp just factory bolts) 304 singing to 7000 piece of piss. I'd do 20mins of racing and then finish it off on the pad only to follow up with a skid comp or something.

    No fancy parts. Just good balancing and machining and a banging tune.


    Edit: stock oiling system too.

    Yes I'm located in Bunbury which is 1.5 hrs from perth. No one will touch my lawn mower in Bunbury let alone a performance engine. All engine work will be carried out by people recommended in perth.

    In regards to the scat crankshaft. I had the same thoughts also, I have a harrop crank with 10/10 off mains and big ends and another set of scat h beam rods with new bearings to suit that are left over from another build here. May be an option to get the crank machined to suit Neo seal and use that?

    Turbo setup will be fabricated by myself using tubular steam pipe manifolds with 4into1 collectors ect so will be as good as it gets in that regard.
    I have morel tie bar lifters to use as. They should be upto the task.

    Ecu will be purchased once I can find someone I can trust to tune the combo and will use whichever ecu they prefer. being in wa limits this a lot.
    Will definitely hit you up for tuner recomendations tk. This has been my main concern being over here.

    As mentioned Paul boz is very good with Holden v8's He's in Armadale I think
    Tune wise Justin at bye performance is great With a perfect reputation
    As is the boys at street built racing, they have there own turbo'd V8's and build and tune with e85.
    Standard delco Computer can work fine if Tuned right.

    ^^^ Rob just went over 800hp 950 odd ft lbs on westends dyno with a cast crank - share some specs will ya . 234-238 cams sounds better , come or csr crank 15-18 psi on e85 and htfo . Old mate went 675 rwhp on 11psi e85 383 torana on micks motorsport dyno .

    Thanks for the insight mate,
    Yeah i've read up on provks setup. its very good and shows how well the reversed casties work. I think he went to a fabricated manifold when he threw the 80mm on? i actually already have a reversed casty setup that i fabricated many years ago but never used. however the setup i am wanting to do this time is low mount and i want to make a good set of manifolds that work as well as they can. If there's hp/response to be had then i'll take it. I'm a boilermaker by trade and run a small business doing automotive fabrication so making manifolds isn't a big deal for me. although finding the time to make them may be a hassle!!

    i also plan to do the tp block route eventually.
