:cry: so wish i had the money for one!!!

this is going to involve a rebore true ?

[MazworxRacing]

this is going to involve a rebore true ?

Not sure what this means :(

[drifter]

He means do you need to use larger diameter pistons as wells as a longer stroke :)

Out of curiosity, what cc does the kit give with which size piston?

[Aj82]

Im guessing at 2.4. If i hadnt already paid for one of the apex kits i would of had one of these. I would have held off if i had known you were making them.
Look very well made.


Cheers Aj

[mikeyb010180]

as above mate this is difficult at the moment both this kit and apex's are the same price lol just trying to get an idea of how much work is involved to get each one in and the benefits

[MazworxRacing]

You dont have to use oversized pistons but it will require custom pistons to move the pin height up etc.

86.5x91mm = 2.138
87x91mm=2.162
88x91=2.21
89x91=2.26
89.5x91=2.29
90x91=2.32

[mikeyb010180]

im assuming that by running oversized pistons would mean that i could run even more boost though due to the larger displacement

[MazworxRacing]

im assuming that by running oversized pistons would mean that i could run even more boost though due to the larger displacement

Doesnt necessarily always mean that. If the motor has more displacement, it may take a larger exhaust housing turbo less lag for example if you are using a .86a/r turbo, it will probably come in less 150-200 rpms on a 87mm bore than a stock 86mm bore. You should also take into consideration the clearance you run between cylinder walls and piston when using stroker kits for good clearance

[ex-ctr]

and for any bore over 87mm [some say 86.5] you need liners

[mikeyb010180]

sorry im being thick but im guessing that a slight overbore say 88 is best with this kit opposed to going for a massive piston

[MazworxRacing]

The factory cylinder sleeves right where the coolant passage meets always cracks under extreme heat or pressure. Sleeving it solves all those problems.

As far as bore sizes, you can go anywhere you want, you have to get custom pistons regardless. Some want to max it out, some want to leave room to play with. Either way, it will make good, useable power depending on turbo sizing.

[mikeyb010180]

just curiously with this kit and all the other replacement parts to do a rebuild capable of withstanding 500bhp how much am i looking at from urselves ? i was going for ur vvl head but i think this could be the better option for the time being then maybe go for vvl further down the line

The package above comes with crank, piston, rods. The only other thing you will need is bearings and pricing depends if you want standard ACL race bearings or Calico coated ACL race bearings.

[Aj82]

I so would have been up for getting the 92mm crank version when it would have been ready!! God dammit.


Cheers Aj

[mikeyb010180]

yh im looking for the other parts too like lighter valves titanium valve springs arp head bolts head gasket all that sort of stuff so literally i have a box of stuff i can give my tuner and say i want all that in there lol p.s do u do holset turbos or only garrett

[mikeyb010180]

[MazworxRacing]

What's the part#'s on them?

[mikeyb010180]

il find out and pm u as there at the garage at the mo see im fairly sure on wat i need piston rods crank wise but its all the other things i need to do to push 500bhp like lighter valves valve springs head gasket them kind of bits p.s wat are ur deliveries like for bloody customs in this country finding and bunging import tax on ? i only ask as my mate just got stung on some parts for his vette

[mikeyb010180]

can u pm me an idea of price for all the bits including this kit pls mate

[Aj82]

Cheers Aj

What are the exact parts you are looking for?

[mikeyb010180]

the lot everything it would take to do a rebuild around this kit and a recommended turbo

[mikeyb010180]

basically if u was going to build an engine to take 450-500bhp with this kit wat other bits would u add in im prob looking to spend about 4000-4500 $'s

You've got mail :):thumbs:

[MazworxRacing]

Thanks for the interest!

[mikeyb010180]

cheers dude il keep it in mind just not sure on the turbo seems a little big and does it fit in the standard position or is it top mount ?

[MazworxRacing]

GT3076R will fit either top or bottom mount. Better top mount. Its not a big turbo. With the stroker and cams, it will spool up in no time and make great power.
