no matter how many mods you put on that 2.5 slow it wont matter the only mod that will make that 2.5 go is turbo so if you want power sell that 2.5 and pick up a 3.5 you will lose 2-4mpg's but will gain some nice hp sounds good to me

isn't that backwards? a high pressure turbo would need time to spool up, while a supercharger is constantly spun by the crank. there would be a parasitic loss due to this. however, a low pressure turbo wouldn't have a terrible lag.

there use to be Supercharge kits made for the QR25DE. seem to range range from 4.5 to 9 psi. although treadstone performance makes a turbo kit that has a range of 5-9 psi for $3200+.

in the history of this forum has anyone that has inquired about turboing a 2.5 actually done it rather then fantasize about it?

thats a dumb bet to make. If you run a small turbo and a decent size supercharger I bet you the supercharger will win. Supercharger is instant power and turbo you can make more power. At the stock engine levels though both of them will be about the same if not the supercharger making more.

keep thinking that son i have done many turbo and sc builds on same cars and turbo is allways faster and makes more power there are turbo's out there that make full boost fast. turbo will always be better than sc its fact son turbo is less stress on the motor than a sc your using exhausr gases to make he turbo go

High pressure turbos with lag are virtually a thing of the past....to a point. Done right, and with a turbo sized for the motor it is being mounted to, turbo is THE way to go imho also. I have owned turbo cars my whole life. IF lag is truly a concern for anyone, be smart and read, read ALL you can about the things you can do with bumping compression for that low end power, and high pressure turbo for that ultimate insane mid to top end power. If done correctly, you will have nearly the best of both worlds. Or phuck it and just go Borg Warner's extended tip turbos.

they make a higher peak power? Thats great if you built so many motors and cars you should know that its the area under the curve. Sure you can have a turbo that spools quick but then it also dies out fast. On these motors stock internals you wont see it being able to hold more then 10psi max before it blows. So if its up to me and I am building a car that is great to drive everyday and will go from light to light I will stick with a supercharger. A fully built motor I will stick a turbo on since I will build the motor to be in the rev range of the turbo I want.

I highly doubt that this kid will be buying a twinscroll turbo or a ball bearing turbo for his car.

No one comes on here, with 20 or less posts and starts talking about a turbo or supercharger and then actually does it. Most people come on here, already having it done, or half way through the process; not going to happen!!

At least the thread got some activity

True and true. This build won't happen. As soon as he realizes it's going to cost more than the combined cost of an air intake and oil change, the project will be put on terminal hold.

There's a better chance of me turboing my car and that's in my "Things To Do Within the Next 20 Years" list.

If, by chance it does happen and I end up eating my words, then I will eat grapes in retribution. Yes...Grapes!
