Awesome, thanks man. Will definately look into getting some!

[MNTLRB]

What are you using the car for, I only ask this as Im unhappy with my outcome, I would rather more response than to a turbo that comes on late and hard, my set up is more suited to drag but I wanted track. The spool time is crap, its like waiting-waiting-waiting-wheel spin.

Fair enough, what turbo& setup are you using? I'm mainly going to be using mine for street, with the odd track/drift/drag, basically looking for an all rounder ay.

[MNTLRB]

Picked up the first lot of goodies today

Shiny new Arias forged pistons 9.5:1 compression

+ piston rings

And, most importantly, stickers....

First step on the way smoky burnouts here i come! lol

[MNTLRB]

Having had a bit of a read through some more stuff i'm thinking i'm gonna definately get some forged conrods and go for a t04z. Would the engine as i'm plannin it atm handle that size turbo? what, if anything, would i need to change for that to work well? The head is definately gonna get a light porting and stronger valve springs, adj cam gears and aftermarket cams plus 850cc injectors adjustable fuel reg and so forth

Also, just thinking about using the TiAL 50mm BOV, would that be high flow enough? I like the sound of em lol but if it won't flow enough i'll go for a another option. What do you guys reckon?

Just make sure you get a twin scroll rear housing and keep it small and get a manifold to suit.

Everything else sounds good. The bov should be fine!

Sweet thanks mate

Can you give me some dimesions there in terms of "keep it small"? And what exactly is a twin scroll rear housing lol

[D_Stirls]

this is a twin scroll system.

The turbine housing is split into two sections and the a bank of 3 cylinders is feed to each section.

Here's a bit of an explanation;

small would be a .81ish A/R or a .84ish split pulse/twin scroll.

will be capable of making 400+rwkw or 540+hp

engine will handle the turbo, depends how much boost you run through it though.

the hydraulic lifters will be 'possibly' the weak link depending on psi and power

Yeh I was thinking .84 which I think is the smallest in split pulse without going to single entry or t3 foot.

[MNTLRB]

Cheers for the link/picture D_Stirls i now get the idea behind split pulse lol makes a lotta sense when ya figure it out!

Okay sweet so .84a/r t04z split pulse and a suitable manifold?

It already sounds awesome just typing it lol I cant wait haha

In terms of a split pulse manifold for rb30's who of the big companies make em? or is it more likely to be a custom made job?

[jangles]

Go with 6boost or Powertune for AUS,

or contact RIPS in NZ, he may be able to help you out locally

[MNTLRB]

sweet as, yeah i know a few good fabricators here i'll have a chat to, just wondering if any of the big companies make em off the shelf like lol

yeah i'll check rips out too, already planning on using a rips intake so getting an exhaust manifold at the same time makes sense even to me haha

[jangles]

these guys are pretty much the big companies when it comes to manifolds i think. apart from japanese gear.

a specifically suited manifold that is as good quality as the japanese stuff locally, offer lifetime warrenty too

did you consider rips building your whole motor? they do something really special with them haha

[MNTLRB]

Yeah fair enough, i'll have a look around see what I can find out

Yeah, they're doing my r34 GTR VSpec II Nur...after i win lotto

lol yeah i did think about it but in the end it was just too expensive, plus to be honest i'm not looking for a car that insane lol

[jangles]

ha yeah, price is always a key issue!

they build mild engines aswell though.

anyway, make sure you get a split pulse/twin srcoll manifold when getting a split pulse/twin scroll turbo.

i still dont think you need the TO4Z for your power goals, but it gives you head room for down the track!

Yeah, I know it's a bit over the top, but i'd rather do it once and do it right, and I just have a feeling that I'd probably end up changing to the t04z later on anyway so I figure I'm just saving myself time lol

And yeah I'm pretty sure I'm gonna get addicted to power hunting (I've already upped my power goal from when I started) so this is playing it safe lol

[jangles]

yeah ive done much the same

[MNTLRB]

Haha and somehow I think it's only gonna get worse not better

so still need some idea on cams, anybody have ideas? Basically want mild gain but don't wanna have to modify the head extensively (doing full recon, mild port, reseat valves and aftermarket valve springs, adjustable cam gears)

anybody know what stock cam specs are for r32 25de head?

go with the biggest drop in cams you can get to suit, i wouldnt bother with the DE cams for what youre going to do.

local to you, and are a great bit of gear

drop in wont even matter.

if the head is apart, u can get it clearanced to suit bigger.for not much more.

something around the 262 9.3 would be good. H182-B

Edited May 24, 2010 by jangles

[MNTLRB]

Yeah, i was never planning on using the standard cams, just wanted to know their specs so I can get an idea of what sorta increase any aftermarket ones were.

For those ones (H182B) I would only have to get the head clearanced for them to work ok?

Also I cant really tell from the website, I assume the prices are US $?
