Ok, so I have my series 1 stag sitting in the driveway and the mind wonders, how do I get more power, cheap and fast, then I settle for a minute and remember the car has to last more than a week. So I guess my question would be how much boost can I put throught the rb25det in it's stock form RELIABLY. Then my next question is, what do I have to do to the externals ie. turbo, fuel pump, blow off etc to get the most boost into my un modified block and head. Any thoughts for a person who's planning ahead? (For once).

i suggest you do some more reading in this forum mate , before getting flamed.

buuuuut , theres so many variables you cant really ask those questions. theres a general rule of thumb that stock internal rb25 don't like going too far past 300rwk and being reliable :ermm: if thats what you wanted to know?

mmm.. i have heard that rule as well.. seems to be a decent guide to go by...

stagstock, judging by ur name you have a stock stag and if 100psi/10 = 10 psi then my year 4 maths has paid off... what else have you got on the car or is it completly stock? I have to ask because for most people stock means bov, exhaust, pod...

if it is really stock then a full exhaust (turbo to tip) will definetly get you more power and allow for alot more in the future...

Ok, well I mean completely stock...... original exhaust, filter plumbed bov all original... not a thing on the car wasn't there when it came out of the factory... except maybe the dust and age

But the first post was more of what I was asking as most people start talking bout pistons n all sort when modding so It rules most of their mods out for me. so I could aim for 300rwkw realisticly in the long run.

Your first port of call should be the RB25 dyno thread, have a browse and see what power people are making with what modifications.

In your post some key words are "most boost" "stock" "RB25", type those in the search engine and see what comes up.

      Post up a showing a a wide RPM range, wastegate duty, timing, TPS, MAP Use 2x rows if you can, easier to read the data. Or just send it to me

      This issue has been there between twins and singles… it ain’t the hot side.

      This actually makes more sense than what I'm suggesting, which would make me feel happier anyway. I just reached for an idea on the cold side because the tests on the hot side theoretically ruled out WG problems. But now that you mention it, it did bother me that a 12 psi spring on what is supposed to be a good WG setup is on able to get down to 20 psi. That's bullshit. Read that way, that WG is not doing what it is supposed to.

      If you have a valve, set to 12PSi, and when it ramps up, it goes out to 23PSi, and then settles for a consistent 20PSi and thats the lowest it will go, then I'd be suspecting you have an issue getting enough air to flow AROUND the turbo on the hot side. Now, this could directly flow into what GTSBoy is saying, and that's effectively that your skinny ports aren't able to get enough of the air through the head. Remember, boost isn't a measure of air flow, it's a measure of restriction. And if the turbo at max bypass around it is still able to deliver more air than the head can ingest, your boost will be up.   In the NEO Head, being NA, you said it's stock, are you on stock cams, and stock springs in it?   Have you tried doing a run with the wastegate held fully open start to finish?
