What does it matter? As if you're going to take what someone says on here is a "safe" boost level, adjust the boost up to that level and just drive away, believing that the injectors are not maxxed out and the mixtures are fine.

For a start, you do not fit any sort of "upgrade" turbo to an R33 RB25 without looking into the engine managemane problem. The problem? That the original engine management sucks balls. You simply must install some sort of aftermarket computer in order to be able to fix that. Otherwise you install your 2510 and then you make sure you do not boost it (assuming it has a decently high wastegate actuator installed on it). And you drive it around with a thumbtack in your right sock to remind you not to boost it.

If you wind the boost up to anything over about 10 psi (plus or minus the various uncertainty factors) the car will start misbehaving and go into R&R. And the injectors will be maxxed out because the mixture settings in the stock fuel tables are well over 100% duty cycle up in R&R territory. This won't matter, because it will drive like a piece of shit and you'll be on here asking why it's farting and spitting and blowing black smoke.

i do have an aftermarket ecu, i have a tuned greddy e- manage i am aware that the stock r33 ECU are very sensitive, if it only makes 10 to 15kw thats still better than the stock turbo and i wont have to worry about bout my stock turbo shitting itself, i did get that turbo for a cheap price.

Just sell it for a profit and buy something that better matches the rb25 then. http://www.skylinesaustralia.com/forums/topic/437073-hks-gt2835-kai-kit-for-ecr33/

Sell it and get a 2530 at least or a hypergear high flow, will make 230-240kw with stock response and save money as you'll just end up doing that eventually anyway, no point getting two tunes when you could just get one and get the power you want straight up

Johnny's right ^^^

Ive still got my 2535. There worthless nowadays. I can barely give it away. My b rother took my spare and the one on the r33 will probably sit in the shed when I upgrade the whole hot side.

SELL 2510 BUY HYPERGEAR = WIN

I've been in a 2510 powered R33, made a little bit more than stock but really wouldn't hold over 1bar-1.1bar to redline. Unless its cheap/free or already came on the car i wouldn't bother.

      RB26DETT Sketchy boost mod?

      By djr81 · Posted

      Bit difficult to follow. Have a look below and see what the standard R32 layout was like. Note there was a restrictor in place immediately before "turbocharged pressure control solenoid" that, if removed, magically got you 1 bar boost.

      I might be way off the mark here.. there must be a T junction under the manifold. That takes manifold pressure through a check valve prior to the T, one side splits out to this bleed off orifice, the other straight to the wastegate actuators.

      RB26DETT Sketchy boost mod?

      By ARB26 · Posted

      Carrying out some engine due diligence before my first drive in a 260RS that has been in storage for 10+ years, and found two lines that are susposed to be plumbed into the boost control solenoid. One of the lines (the wastegate boost supply line) to actuate the gates, had a bolt in one end blocking it. The other line (main boost signal line) from the very rear of the intake manifold (RB26DETT) and runs up to the boost controller had this pill in the end of it as seen in photos. Other than the obvious (T28 Ceramic turbos might well be cooked)  Can anyone shed any light on if there is any validity at all with this mod, bleeding a constant fixed rate of manifold boost pressure off through this 3mm hole?  Is it deliberate?  Was this a 90s Jap mod done to RB26's? Or has someone just fitted this without any idea of what happens to ceramic T28s if they are not gate controlled?

      This looks great! Awesome to have the 5 speed with an LSD in this. The Recaro's look like SR2's or SR3's. It's a shame they've been retrimmed as they would have looked sweet in their original colours. I think I'd want my agent to be a little more up front and informative too. I've never imported but I reckon it would make me a little nervous, so the more info the better.
