Very interesting, thanks for the detailed response.

Another popular oil for big hp engines is Castrol Edge 10W60.

Well power=flow and it is the flow thats causing the overheat. A particular size housing will only be able to flow X amount of air at a reasonable temp. What do you mean will the rear housing be enough for him?? I thought you didnt want anymore power? Surely Garrett can supply this information to you? I have attached a plot from the Garrett site comparing the different exhaust housings. Seems to be a significant difference in flow capability between the 0.82 and 1.06. I would be also reading through the thread below and pm'ing all the guys with the 1.06 rear housing: http://www.skylinesaustralia.com/forums/Gt...l=T04Z+database If not enough info here the vl boys on calaisturbo would most likely be able to help.

I dont understand this the 0.82 housing on the GT35 cannot survive the amount of power and therefore overheats. Your initial comment of not wanting any more hp but then saying that if you stayed with Garrett you would choose a larger turbo. Why would you not choose the 1.06 housing on the GT35 for a slight increase in lag but very similar hp and hopefully some reuse of turbo parts with your current blown turbo?? It would have to be THE most common aftermarket turbo used on an RB30 block.

From this garrett link they keep using the figure 10%: http://www.turbobygarrett.com/turbobygarre...bochargers.html So I would say roughly 10% more than what they do now.

Why not stay with the GT35 and use a 1.06 housing and then drop the boost down a tad until you have similar power to currently? You could even use one of the new GT35X turbos.

Well we are talking about 2010 mustang. Which mustang came out of the factory with a supercharged V8?

Nope a std R35 GTR would slam a std Mustang down the strip on any tyres u want.

Supposedly there was a 1000hp R34 using the nistune ecu at some stage with great success. Plenty people on here using it well above 400whp.

OOOOOOOOOO dont these look good. GTX3071R for me thanks I wonder if this will expand what they can get our of their GCG hiflows?

That is a HUGE gain! the difference in response is fantastic. Me want

Wait till you own one and actually want to use your tray, they suck! I love the ford clips on the outside they are so practical and easy to use. Have used them in so many different ways, I guess it depends on whether you are buying a ute to use or just to look pretty

Surely all these turbo suggestions will be more laggy then his current GT2530 though??

I used these 800cc direct fit injectors into my R34 GTT, Trent installed and tuned them: http://cgi.ebay.com/ebaymotors/DeatschWerk...sQ5fAccessories With the US dollar great at the moment they will be even cheaper then what I paid.

Oh so you want more response they you have already? I think disco has been posting up bigger turbos as the first post didnt really say which way you wanted to go. If you want more response why would you choose a 2871 or bigger? My understanding is the GT2530 is closest to a GT2860RS.

I didnt think cops bothered pulling people over for less than 10 over anyway. Its more the fixed speed cameras that will get your for 3-10 over and the radar detector wont help for those. You are better off getting a list of the fixed cameras and memorising or loading them as points of interest into a sat nav.

Another great result, geeze VCT makes a huge difference in response! VCT on would be my choice

As others have already said. Geeze your game doing an engine conversion yourself on your first turbo vehicle!

At least try a turbotech bleed valve, they are excellent and cost around $30! Dont worry about the multiple boost settings etc, just get it right and leave it.

Very interesting point, makes sense.

Garrett engineers on their website clearly state that the less restriction after the turbo the better. Sure this needs to be weighed up with physical limitations and noise levels etc. But a greater flowing exhaust can only improve response and top end power. Obviously, whether its even noticeable depends on your power levels but at 400rwkw I think it would be very noticeable. Just because some cars manage to get 400rwkw through a 3" exhaust doesnt mean they couldnt be a heap better with a larger exhaust. Min 3.5" IMO

What has changed since? QLD is still the most leanient state in Australia regarding car modifications. I have heard of people with turbos on commodores paying $50 for a mod plate as opposed to a 3k adventure down here in Vic. Not to mention the RB30 conversion is legal in QLD and not in VIC. etc etc

Find a successful engine builder in your area, tell them your requirements and let them put together a proven package. If the engine builder hasnt used your combo before he wont have had the experience on how to set them up to be the most reliable. Building a reliable engine with moderately low power is not about using the best of every part but getting a proven package that works well together. The best example of this is a factory engine.

+1 Remember that is just one engine builders advice. Whats to say he didnt setup the engine with the Tomei pistons differently and blame the cheaper pistons?? At least have a chat to a few other engine builders and get their opinions. But if you have already decided and willing to go against everyone here then just do it.

Get a list of what they want to fix and post it up here. That way we can help you out to see if its urgent or maybe you dont have to do it all right now.
