not sure of the exact specs denham

but its got a pretty huge ex wheel and housing on it

on my mates sr20 he runs 26psi but his has a smaller housing and wheel on the back - makes bout 300rwkw

i know that there r other turbos out there that can make that power at lower boost levels - but when ur paying 900 for a brand new t04 what am i to whinge :P

  • 2 weeks later...

no its chromed its all a bit dirty at the moment and not quite finished but its working out well so far boost response is alot stronger and im having heaps of fun with the external wastegate pipe and pedestrians. the gf rekons it sounds like its goin to hurt someone or sumthing

here she is all bolted back in place.. car goes as well now as it did before on 13psi now only using 9psi so im happy tune up will be soon ill keep you all posted.

Did u manage to hook the 2 springs onto the clips with your xtr thermal blanket?

I am having a bit of a problem getting my to clip on

Hi guys, a lot of people look at the other upgrades (cams, porting, manifold etc), on a turbo car, as a way of increasing the maximum power at one particular rpm point. That's not what I do it for, I actually use these other items to increase the average power over the used rpm range. I also use them to reduce the amount of boost I run to achieve the same maximum power, this increases the responsiveness of the engine as well.

A comparison;

1. I have an RB engine that needs 1.6 bar to achieve 600 bhp with standard cams, ports, lowered compression ratio (thick head gasket) and a combined dump. It has 360 bhp average power (4,000 rpm to 7,500 rpm).

2. The same RB engine that only needs 1.3 bar to achieve 600 bhp with 264 cams, ported, manifolds matched, standard compression ratio and a split dump. It has 440 bhp average power (4,000 rpm to 7,500 rpm).

Some people would say that I wasted my money on the cams, porting, split dump etc since I still only have 600 bhp. I would of course reply yes, but I have a 22% increase in average power, so the car will be substantially faster. Plus the response will be also dramatically improved by the enhanced breathing, with better off boost performance and faster to build boost.

Hope that makes sense.

sure does

ur peak power stays the same but ur power over the rev range to acheive that peak power increases

torque would increase over that rev range to achieve a faster car lower down, resulting in a faster car at higher speeds

correct?

    • Robertson was a Canadian inventor, and it absolutely reigns supreme here. 95% of our screws are Roberston. It's literally the only option you can buy off store shelves. What would it have lost out too? I believe it's also very popular in the US.  My reference to imperial was pointed to both NPT and BSP. 
    • No. BSP lost to the cultural/technical imperialism of living next to Trumpistan. Face it, Robertson screws were better and still pretty much lost out to the yank stuff. The Europeans hate the Brits and they don't use NPT. NPT is just as "imperial" as BSP is, being based on those useless inch thingos. Just done differently. 
    • I live in Quebec. Our license plate slogan is "Je me souviens" Translated is "We will remember" as a reminder to when England conquered us and that we must never forget what they did. Long story short, BSP is unheard of here due to being an English design. I'm surprised our nazi anti english government office the OQLF hasn't kicked in my door yet just talking about it, yet alone imperial anything.       
    • Thanks for that! I did a quick Google search looked up some of hydaulic stores and didn't see it listed on the website, I'll give them a ring. Also found out later that I can buy 2 oem bleeder bolts for 10 bux and come with the washer which I might do so I don't waste the money it costs in petrol to find 2 washers (already did that lol). The old copper washes look in good nick, I drove it after taking it off and putting it back on and didn't see any  Part number here for reference if anyone needs: 14053-42L0A
