Since you have been doing intake pipe work you may be leaking boost. Do a pressure check that would be the first thing I would check. Make sure all your seals are tight.
You are correct. For that price you only get the shortblock; the head is sold separately. Look into getting the Long rod option. I have done some research on them and may be worth the extra $200.
Doesn't Road Race sell test pipes with the cat heat shield welded on? You cant tell that you are not using a cat from a visual inspection.Check out this thread about 2/3 way down.http://www.dsmtuners.com/forums/showthread.php?t=115996&highlight=rre+cat

I just bought a townhome in Philly. And it has a small one car garage. There is only about 3 1/2 feet in front of my car when it is parked in there and a couple feet on each side.Is it going to be a bi*** to do any modifications to my car in this small of an area? I currently work in my...

They cut the housing to create turbulance after the turbo thus reducing the effeciency of the turbine and reducing boost creep. Thats why people can turn the boost down and not creep with this internal gated turbo. You will reduce the creep but loose flow capacity and a little top end.
THe PTE exhaust housing only comes with one A/R option even though they say .48 or .63. The PTE housing comes out to A/R = .55. Do a search I think that is right though.
That test was only done with a small 16g turbo which does not have a lot of top end anyways. So the top end is not that different between the set ups. It would be nice if they did a test with a larger turbo to see if the 264/272 and 272/272 combos fair better.Also the link says that the...
Are there any losses when upgrading to stiffer springs. Like more resistance to cranking due to the spring resistance? It would make sense. Any thoughts?

Would you expect to see similar timing for both the standard 2.4L and the long rod 2.4L or are those increases just because of the slightly better rod ratio?
Going to answer my own question because I found the answer here:http://www.swordfishgsx.8m.com/photo4.html"A longer rod reduces peak piston speeds slightly and delays peak piston velocity until the piston is further down the bore, which gives the intake valve more time to open more...
Euphoric is right. Nanokpsi and GSXJEFF, you guys are forgetting about the hot side of the turbo.You would be right if you just changed compressor wheels, the only difference would be the efficiency of the compressor wheels.But most big turbos have bigger turbines and exhaust housings...
Pardon my ignorance, but what is the tongue of the housing? And when you say it is symmetric do you mean that the center of the volute is centered with the turbine's inducer width or the whole turbine width? And why would this be a benifit since the turbine is not symetrical itself (ie. the...
A/R ratio is just a ratio and can have different flow rates and spool with the same ratio.My question is how does the full garrett 4 bolt 0.48 A/R housings compare to the mitsu 7 cm housing? Both have pretty much the same A/R. But, what is the Area (A) and what is the radius (r) of both...

Damn, your still not getting it!To extrapolate on your example: Take your two liter bottle but this bottle is different it has 2 necks and the water travels from the bottle to the first neck (engine restriction) then to the second neck (turbo restriction) then outside. The first one has a...
I was looking through Maximum boost by Corkey Bell and he talks about a reduction in throttle response when the air meter is further from the throttle body. So in this case the blow through may have better throttle response because the low pressure air pulse when opening the throttle passes...
My pipe/straw analogy was just to help 14.5 visualize the difference between flow with more and less restriction. I was not talking about just the turbine housing. Re-read what I said in context with his questions.I still dont see how you can say this. There is a significant difference...
Most turbines speeds are limited to the tip speed hitting the choke barrior which is about the speed of sound 1100 ft/sec. But the speed of sound changes with air density so it may be a little higher than that inside the compressor housing.
Try thinking of it this way. If you blow through a straw (small turbine) it will be hard to flow a lot of air because it is small. Air molecules build up and create pressure. Your lungs will strain due to the psi in you mouth (exhaust manifold).Now if you blow though a 3" pipe (big...
You are thinking of psi and flow as the same thing. The exhaust manifold may have less psi but be flowing more, more energy to spin the turbine but less psi.To continue your example, say you blow through the T88 it will take more breath because it is less of a restriction. Just imagine...
Maybe if I explain it this way it will help:Say you have a 16G turboIf you look at the turbo map you will see that it takes a shaft speed of about 115,000 rpms maintain a PR of 2.0. And say at 4500 rpm (engine speed) you are moving 250 cfm...
No, the smaller turbo is MORE restrictive. You have to think in terms of flow. Once the bigger turbo is spooled up it will take less exhaust manifold pressure to create the same intake psi.
