| :same goes for the VG, so what's your point? My point is that the VG will *always* be ahead of the SR in power production. Since the purpose of modding your car and swapping engines is to make *more* power, it would be counterproductive to swap in an engine that is already at a disadvantage. The VG will always be ahead. And since the VG is already in the Z, it's simply not a smart idea to take it out and put in a less powerful engine. :But just to shoot you little theory in the ass the SR that, signel is running T88-33D turbo with over 700 hp but it’s in drag set up, in circuit car set up it used a T78-33D but has factory backed and a stroker so I didn’t use it. This doesn't shoot down my "little theory" at all. Take a look at the money it costs to make a SR20 produce 700 hp. Now compare that to the money it costs to make a VG30 produce 700 hp. Also, take a look at the powerband of a 700 hp SR20 and compare it to the powerband of a 700 hp VG30. Which one would be more streetable? The simple fact is that with less displacement, the SR20 will never deliver as good of a powercurve as the VG30. It will always be playing catch up, and when you apply the same tricks to the VG30 it will once again come out ahead. And if you've read my posts in the past, you'd see that I'm not even much of a VG30 loyalist. The VG30 would be at the same disadvantage if you compared it to a turbocharged Q45 V8 engine. There really is no advantage in using a smaller engine when it comes to producing power. Modding an engine is always about tradeoffs, and the smaller the displacement the more driveability tradeoffs you'll have to put up with. :and parts and labor for the swap and to make the SR very high HP are cheaper then the same for the VG swap, in the HP vrs liter. Let's not adopt the riceboy mentality and start talking about power per liter. That's a mindset that they've fabricated to serve as a handicap. Power per liter doesn't propel your car, power does. The smaller the displacement of the engine, the more power per liter the engine will make. I've gone over this before. I can install a R/C car engine with 600 hp per liter, but it won't push my Z very fast. :It’s not very labor intensive, there is much more room to work with and much less would have to go in to body modding with the SR vrs any turbo kit on the VG that will require the frame to be notched and reinforced. We can make plenty of HP with the VG without messing with the frame. By the time you're using TD05-18G's, the car's streetability is already beginning to go downhill fast. :also i think you need to go back to the statement you made about the peak tq, that's what you where basing your micky mouse opinion on and that's where i proved it wrong. now you go a change it to the over all area under the peak. Make up your mind. You are trying to make it look like my statement is inconsistent. It's not. I said that the SR has BOTH less peak torque, AND less area under the torque curve. It's a lose/lose situation for the SR20. With 1/3 more displacement, the VG can afford to offer more peak torque AS WELL AS a better torque curve. This is the advantage of more displacement. :You say that about bsters having much more aggressive cams. As you can see the last SR with the larger turbo suffers from the same thing. But you ignore that fact. LOL I'm not ignoring any fact. I don't think having very aggressive cams and a sky high power band are very useful in a street car regardless of the engine used. I wouldn't put in an engine that's modded like B-ster's, and I wouldn't install an SR20 like that either. I don't see what's so surprising about that. I like streetability.
:umm are you comparing the stock turbo VG vrs the mid turbo? cuz that’s what it sounds like, so yes it would pull ahead quicker. NOW, (sense you bitch about bster`s dyno I will do a handicap comparison.
I'm comparing the VG vs. the SR that was producing roughly the same power. To compare engines objectively you should be comparing them at the same power level. Don't try to throw in handicaps. :So if you reverse the situation, Ashs big HP VG barely makes 200 rwtq at 4.4k where as the stock, but tuned, SR makes 200 rwtq at 3.1k. Pretty ironic, eh? Or BOTH larger turbos motors BOTH hit 200tq at 4.35.. want to look at tq under the curve? Think I blew that one up too. The only thing you blew up were some neurons in your brain trying to think of a clever post (you failed). Now you're comparing the driveability of a stock SR to a 700+ rwhp VG. As I've stated previously, modding a car is about tradeoffs. If you want a 700 rwhp Z, you're going to have to give up driveablity. What you are saying is that the stock SR20 delivers better driveability than a 700rwhp Z. Look what the SR20 offers you, though. The VG is putting out MUCH more horsepower. It's not as streetable but you *do* get something in return. With the heavily modded SR20, you're still at a displacement disadvantage so you'll always be at a streetability disadvantage compared to a similarly powerful VG30. :please I set them up stock turbo vrs stock. Mid sized vrs mid sized, and large vrs large. You are asking for handicaps now. As I've pointed out, the SR will *always* be at a disadvantage due to its smaller displacement. You can't begin to handicap the argument by comparing them by turbo size, etc. They are engines- you compare them by power output. Put a 400 rwhp VG30 next to a 400rwhp SR20 and compare the powerbands. Or compare a 700 rwhp VG30 to a 700rwhp SR20 and compare the powerbands. Due to its larger displacement, the VG will always deliver the better powerband. :how about you compare the liter per HP. that's a much better way to compare. The SRs used are 205 BHP versions. (There are 215 bhp SRs that are putting out 270 and 270 with bolt ons.) So the larger turbos on both motors come out to……..270RWHP per liter on the SR and 244 per liter on the the VG… LOL!!!! You've really lost it now. Resorting to "power per liter" comparisons is pretty damn low, not to mention meaningless. The smaller the displacement, the more power per liter you'll have. Find an RC car engine and look at their power per liter. They are 600+ HP per liter. But you know what? It doesn't mean a thing other than the engine is really small and revs high. It doesn't say anything about the technology of the engine, since the 600+ hp/liter RC engines use technology that's been around since the 1930's. The fact that you even bring up power per liter in an engine discussion makes me think less of your reasoning ability. I was willing to overlook the fact that your spelling is horrible, that your brain seems to lack the resolution to construct a well ordered sentence, that you can't apply logic to concepts, etc. But when the fundamental idea that you hold is just plain wrong, and you resort to lame tactics to try to "prove" your point, I can't overlook that. My final statement to sum it all up is this- The SR20 is a great small engine. But with 1/3 more displacement, the VG30 will always have the advantage in terms of power production. What you do with that advantage is up to you. You can have it produce power similar to a modded SR20 but have it deliver a much better powerband and much better streetability, or you can have the VG30 be just as streetable as the SR20, but have it produce much more power, or you can have a little bit of both and have it slightly more streetable than a SR20 and have it producing slightly more power. You just have more to work with.
