srt-4 vs. Gts which is best buy?

how da hell did you get a T25 to flow that much air to get up to 250whp? you did this on a AWD dyno? can i see some dyno sheets? can i see what psi your running? i mean T25's can only physically spool up to 19psi anything higher and wheel compressor wheel will shatter. at 16psi your already hitting the max efficiency of the turbo. so by boosting any higher then that your not really doin much. even SR20DET's running stock T25's have a very hard time gettin past 210whp. in fact, i have yet to see one go that high yet. and they are both 2.0 liter but the SR has a more efficient drive train compared to the GSX. ( not the GST though )

When was the last time you shattered a compressor wheel? LMAO. I ran well over 20 psi. No problems. 117 octane race fuel took care of the knock. I would never waste 100 bucks or more to dyno a POS t25. See below.

at 16psi your already hitting the max efficiency of the turbo. so by boosting any higher then that your not really doin much.

This is true. On pump gas. Anything over 16 psi on a 2 liter motor (never leave displacement out when quoting boost numbers ) is making a lot of heat. You need race gas to allow safe operation over that level.

even SR20DET's running stock T25's have a very hard time gettin past 210whp. in fact, i have yet to see one go that high yet. and they are both 2.0 liter but the SR has a more efficient drive train compared to the GSX. ( not the GST though )

I dont know much about the nissan motors, so I wont discus much here. I ran up to 100 mph on the t25 in the quarter, in a car that weighs 3350 with me in it. That wont be possible wih much less than 250 whp. I didnt have to dyno the car. Other people that ran the same times with the same weight have already paid that bill. I'm not the only person to have done this. some people claim to have gone even faster, though I have never seen it myself. Also consider that the DSms make ~170 whp stock. To go from 15 flat at 90 to 13.7 at 100 takes more than a 40 whp increase In my personal experience (the math says the same thing too) it takes about 10 whp to gain 1mph and .1 seconds at 3350 pounds. That rule of thumb easily backs up the 250 whp claim.

But hey, its all bench racing after all. Most people upgrade that shyte turbo long before they even attempt to max it out anyway. Its a lost cause Dynoing on the T25 is a waste of cash, so thankfully other poeple have done it, not me.

Another way to look at a turbos potential is the 1 pound per minute equals 10 HP rule. A t25 will flow up to 25 lns/min if you push it. I used to datalog it. In comparison a 14b is good to 31 or so, 16g to 38. My turbo, 65

If you donthave personal experience with the turbo, it doenst make sense to spread rumors about how weak it is or how it "shatters" over 19 psi, etc.

yes because those evo's run only on race gas...since they run 19 psi from the factory and have a 2.0 engine

Not FWDs, thats for sure The occasional fast RWD rx7 or supra, the rest of the field is dominated by AWD dsms. The slight power loss you get from the rear drivetrain is overcompensated for by the massive launch advantage. Find me a SRT4 pulling 1.5 second short times. I do it on all season street tires. When I was running mid 13s short times were 1.7s. The whole comment about losing traction on hte front wheels is retarded.

While I will admit that FWD isn't good for drag racing I will also say that AWD isn't that great either. With the added weight, drive-train loss, and durability issues it makes it a far cry from being ideal for drag racing. And there isn't a "slight" power-train loss with AWD either. I just don't like people touting AWD as the best drive-train for drag racing when it is a far cry from it.

Who cares if people are getting SRT4s in the 12s for 1500 bucks, DSMers have been doing that for the last 10 years. I did it on my 2g.

And who cares that DSMs have been doing it for the last ten years? Dodge has been doing it since the early 80s.

The turbo on the SRT4 has a TDO4 exhaust side last I heard. Thats going to become a major limiter especially with higher displacement of the 2.4.

I would highly doubt that since the SRT-4 turbo is capable of well over what a TD04 could produce. It is a Mitsubishi turbo but the exhaust side of the turbo is cast into the exhaust manifold. So that would make me doubt even more that the turbo is a TDO4.

I highly doubt the stock bottem end will do 1000 HP. Sounds like more misinformed misguided ricer magazine BS to me.

Go ahead and doubt it, there are guys that are running 9s in the 1/4 mile with the SRT-4 on the stock bottom end.

If the SRT4 has more potential than the DSMs why are DSMs still smoking them. Oh yeah, theyre "new." When my DSM has a 2.4 in it in about 2 weeks we'll see what the potential difference is

Sorry but stock for stock the SRT-4 has you beat.

210 whp on a stock t25 is absurd. I made 250.

Bullshit! You had better have some dyno sheets to back that up. With the small amount of airflow and the fact that you are AWD I am calling bullshit. Your car only puts 210HP to the crank stock.

I'm sure everyone will now say that my car is heavily modded, or whatever, but I still have spent less than one would on a SRT4. Including car, upgrades, and all breakages/repairs and other so called AWD disadvantages. Dont get me wrong, I think the SRT4 is an awesome car, especially after riding in SBRs car. But lets not get caught up in the hype here. Give the car time to prove itself. Until then, there is still more potential from a DSM, more aftermarket, turbo options, etc. Not to mention spare parts are partcially free for these things. A local guy just gave away 4 0r 5 good 6 bolt blocks to make more space. Transfer cases, trannys, etc are dirt cheap. Maintenance is cheap on a DSM unless youre one of those tools that goes to the dealer for every squeaky belt that comes up. In that case, like I have said before, go with the warranty. Do us all a favor and do not buy a powerful car that actually has traction.

1. Yeah, the SRT-4 will cost more because it is brand new! Your car is used. You can't compare price for mods here including the car. I would say mod for mod they would be about the same price.

2. Give the car time to prove itself? Why, when Chrysler has been reliably turbo-charging cars for ages and with a good amount of power. They know what they're doing. Also, aftermarket, you have a damn good aftermarket for the SRT-4 and even better since the staged upgrade kits keep you covered under your factory warranty, sorry, but you can't do that wit your DSM.
