Owes me double what I am selling it fow (actually a fair bit more).

...and please call 0407 801 338 for enquiries. Will ship interstate.

How about a massive price drop to kick start some interest... $23K!!!!!! - now has launch control configured with Vipec V88

PM sent.

Bump time!

Brad, I thought the TIlton still used plastic parts internally... and the Weldon was all steel and rebuildable.

Hi Ash, would you sell S3 Xenon headlights separate from car?

No need to get defensive, anyone can PM me if they like. I did not say it won't make power, etc... but the port looks polished from the photos. If it is, then in my opinion, it won't flow as well as it could at certain engine speeds. The +1.5mm intake valves might be an issue too, going too big a valve can hurt flow around the valve head at lift "valve shrouding"... the head of the valve can get too close to the cylinder wall.

He might have a little bit of knowledge but if those inlet ports are polished (which they kind of look like they are) there are deficiencies in how that inlet port will perform... that is the bottom line, it is FACT! Whether he has built 10 engines or 100 means nothing. Plus the fact that this head also has +1.5mm inlet valves is a whole other issue... I don't think it is right to continue this on Piggaz's thread, apologies mate. Marcus send me a PM or email if you like.

You are the brake master Roy

Yeah, I think you may be right there. Yes please do thanks

Bobby, was there any consideration as to the the angle at which the injectors are facing in the inlets of the plenum? The way they are it is like they will be spraying almost directly onto the opposite side of the runner and not down the runner into the port.

He is reading too many books and playing with RB34's at the moment Come on Mike!

Any updates Brad?

Yes it has!

Not fun? Do you wear beige knitted jumpers every day?

Dan, if you have a spare upright I can copy the design and make some drawings so someone can fabricate one. If you have one from a R32 or R33 that would be good.

Give me a call tomorrow after COB.

Go ahead... All I am suggesting is that the port looks polished from the photo. To enhance mixture quality it is better to have a textured inlet port surface, especially considering you have massive injectors that wont atomise very well.

Have a look at the inlet ports on Brad's engine (SHOWOFFR32)... that is what they should look like.

If you dont intend to do much more just go the smallest housing and see how you go.

You need to choose which direction you want to set up your engine and turbocharger. Low back pressure system: significant head porting, properly design tubular manifold, larger A/R turbine housing and camsahfts with some overlap... aim for 1:1 exhaust manifold pressure and boost pressure. High back pressure system: the OEM turbocharger set up is a perfect example, higher exhaust manifold back pressure to boost (i.e. maybe 2/2.5/3.0 - 1), no overlap, short manifold runners, small A/R turbine housing. You can't do a mix of both as each one will characterise how the engine will perform.

Let's see the door trims!

Will you be going for low exhaust manifold back pressure and cams with some overlap? If you are, then go the larger rear housing but expect less performance at lower rpm. If you don't have a lot of head porting and have zero overlap go the smallest. I am not sure what the runner diameter of the 6Boost manifold and the lengths of the runners but that is also a consideration.

So without dwelling on it too much more what turbochargers were you using and what was overall opinion on the twin configuration? It was a very packed engine bay with it all in there. Having been through the twins already, retropectively would you have gone a single EFR or would you in future?
