Thread: Well... here was the culprit

Another thing, im a newbie when it comes to turbos but I was looking at some website and it said something that the w11's had different turbo's than traditional sr's. They have t25bb's? I read about those and supposedly theyre more durable and better than the regular t25 turbo. Is this true? I'm thinking about just using my old t25 for the next build for the first few months then upgrade to t28 when i get the money.

I would just go with a GTiR T28. It will fit the same manifold, though IIRC some people say you need to shave the block a little bit, unless you use a GTiR manifold.

or go with a 2871 or my bb37 and have almost the same spool as a t28 and the possiblity of 400whp later down the road.

I got a GTiR t28 and GTiR manifold I don't need, hit me up if you need it

By the way, a T25 can be happy at 14 psi on a motor that doesn't flow well for what ever reason (crappy cams, crappy intercooler and charge pipes, etc.) but absolutely overworked on a motor that flows well. It's nothing to pressurize a glass jar to 14 psi with a pin hole in the bottom, it's another thing entirely to pressurize a glass jar with a large hole in the bottom.

yeah 14psi on a good setup shouldn't do that. Something is amiss

I think ben is referring to his setup, since it blew at only 9 psi. You are misunderstanding ben's post.

It was obviously very bad detonation, maybe something went wrong before it happened. Failing fuel pump, or bad fpr or something. Make sure to test everything, so something doesn't happen with the new engine.

Yeah, I am probably getting a new fuel pump, injectors, fpr, and alot of the electrical stuff for the new motor. I am stripping this car down and restoring everything in it. Hopefully have it done by Julyish.

Oh sorry I was just making a general statement,to subscribe and get back to this.I see how it looks like it was a reply to benfenner :o I should have read the whole page

Ben does seem to be trying to make a good point. If the system has boost leaks just for example the motor isn't seeing all of the boost made, so it is under less stress. It is seeing 14lbs for a split second instead of right after the turbo gets going. Also the leaks are going to make the engine run richer and cooler with all the extra fuel, preventing the detonation. I disagree about the right intercooler contributing to detonation though, that is what it is there to prevent. It is also where some ebay cores hurt flow and why it sucks to have high pressure drop. I don't really see how cams are going to hurt much either unless he is talking about exhaust reversion. If that is the case I haven't heard of the stock cams being that bad.

Care to explain more on your thoughts ben?

What fuel where you using?
