xsiv monsta b16a build motor in 22-11

[xsiv]

it is finaly time to get my motor asembled.
i prity much finshed with the car, it ready for paint now
but i have two options.
me and my brother were going to bulid a sleeved b18c for my bro in oz but he found a block over their, so we are going to sell one setup

what im looking for
i would like to reach over 300kw atw, and for my turbo to be a bit lagy to make it easyer to drive,
the car will be at the drags and maby a track day.

i curently have a t3/to4e turbo, ile be running the motor in with this turbo and then changing to a gt35/40 or to4z, well somthing along thoes lines

the choice i have is

b18c block
dart mid sleeves
je pistons 81.5
eagle rods
type r oil pump
acl race beerings
b18c crank

or

b16a block
darton mid sleeves
je spr pistons
eagle rods
eagle stroker crank (Race ballanced to 9500 rpm)
type r oil pump
acl race bering


the head will be the same on both motors

type r head.
typr r valves
mild port job
aftermertik valve springs (still looking so pm me if u have some)
ti retaners
huge aftermarkit alloy intake mainfold with 75mm tb
custom stanless steel turbo mainfold.
type r cams - (will be getting some turbo cams if i need more power)
adjustable cam gears (still need to get some)
3" stanless exhust

i have a link plus running it all with 880cc injectors
walbro 255 intank full pump

now i have to decide on a few things
wastegate i was looking at a 38mm tail (will this be suficant for 300kw)

clutch (i have a std b16a 1 clutch and a 4 puck brass button clutch plate)

fuel system, i think i will need a surge tank, and a nother full pump. i was thinking of mounting the surge tank in the engina bay with a bosh fuel pump.

arp head studs, or type r ones??

std head gaskit and cam belt??

i would personaly like to stay with the b16a but now i have the other option ????
the motor will be going in to be bulit with in a week.
if i have missed anything let me know as i dont want to kill the motor
hear are a few pics of the goodies

Whered you get your stainless bends and flexipipe from dude?

[phonix]

B18 Block with typeR head will be a nice combo, follow the recipe used by the guys in states, it's been proven time and time again.

[xsiv]

yeah the only thing is i like to rev, b16a with stroker has a better revabilty

i got them of this forum, try tube and steel maby???

[nemesisteg]

i cant see why you cant go with the b16a, i mean with the stroker you have the same fuel capacity and like you say greater revability, revving that high can be scary with 20+psi tho lol. as for wastegate my assumption would be 38mm would be getting a bit small for over 20psi, i cant imagine you would need a surge tank unless you plan on doing alot of track racing etc, otherwise if its just the odd track day keep it over half tank during the track day and you should be fine, as ive recently experienced the surge tank set-up can be quite a pricey one, ive spent over $900 so far and i dont even have all the AN fittings yet

[americ_ian]

10,000rpm + 20+psi FTW

yup 1/4 tank full and i get surge issues

but then again my Ek needs some weight at the back :wink:

[BTLF3D]

Yes a 38mm will be suficient as long as:
The placement is in the right place
You have a good EBC
You have a larger than 40mm (i think) dumppipe/tube off it

You will definately need to upgrade the clutch, a std b16a one wont cut it, something like a uprated Type r one, or a Full aftermarket clutch (ATS, Exedy, Xtreme) will/should work for 300wkw.

Type r headstuds would just be the same as normal b16 or b18 headbolts wouldnt they? i would run ARP headstuds and main studs just to be safe.

Standard Headgaskit is fine, unless you go for bigger bore/pistons.
Also Standard cambelt is fine.

IMHO if you are sleeving and spending all this $$ i would go for 84mm instead of 81.5, much more power/torque you can get on lower boost etc...

[xsiv]

yeah i fully should have but i wasnt going to sleeve it , last minut change.

Having a laggy turbo will not make it easier to drive

I think he means easier to keep off boost, which it will be. On/Off powerbands do suck in anything but a drag car though

[xsiv]

yeah thats right,

You do realise the more boost you run the less need there is for the waste gate aye?

[nemesisteg]

yeah well the more boost the more the gate just stays open i guess, anything over your normal boost levels would be taken care of by the EBC, just would have thought a larger sized valve would be required to vent off excess boost

other way round... the more boost, the more the gate stays shut.

[nemesisteg]

really?? ive never studied how a wastegate works but i would have thought by the amount of noise that comes out of my screamer pipe that when on full boost the gate is venting more...

the wastegate is a valve... when the valve opens, more exhaust gases come out, so it cant spool the turbo as much.
When its closed, it will spool alot more than when its open.

Nah your external is venting nothing before the preset boost level is reached that is the beauty of external WG's comapared to internal. Faster spool.

[xsiv]

thets quite inresting, i though the gas amoint out of the engin would increase when full boost and top reves are hit. i think it be a bit of both ideas

If you wanted to run 10psi sure it would be a problem but 20psi not likely...

you can run 10psi on a 81.5mm b18c on a 38mm wastegate too

I disagree. Internal gates and external gates both use the same diaphragm based actuating method, they both creep open early. This is the case with any proportional control method.

External gates allow you to run a much bigger valve relative to the cross-section of the pipe and also flow better.

To prevent the gate opening early you need some form of electronic or other controller which can hold the gate shut below the required boost threshold and then open it hard when required.

Well compared to a internal w/g they're less prone to creeping open early in a attempt to regulate boost. You can often see an increase in spool time with a external w/g.
