Turbo or Supercharger for 5AT

Looking into getting either a turbo or a SC, but not sure what would be best for the 5AT. I am kinda thinking that a SC would be better since you dont have to wait for the turbo to spool up. But I really dont know, any comments could help

I agree with him i want to get a turbo or supercharger as well! Personaly i want a turbo kit, but all the threads on this dont go into real detail on what has to be done for the 5AT coupe. I know the 5AT can be converted so the turbo can fit it, but what is EVERYTHING that needs to be done. I want a ball park figure on parts to make around a 400-475HP ...daily driver (instalation is going to very everwhere so dont include labor).

Thanks

Hey.. I have an auto TT.. if you want 400-475rwhp.. you can just get full exhaust, TT kit and kinetix SSV manifold.. tune it up.. ull be there - as for what I had to do.. nothing really that was a big deal except for have the original ECU reflashed for your AUTO car.. thats what I did, sent it to Technosquare in Cali who flashes them.. and the Greddy eManage I just kept

I think you're going to need some work done on the trans if you want to push that kind of power. At least a valve body kit from SGP, Level 10, or Stillen and a tranny cooler - 340 to 360whp is safe for stock internals and tranny - that's what I've read anyhow, could be completely wrong. I have a 5AT myself and would like to go FI, untill I find a replacement 5AT tranny cheap though, I'm not going to change anything.

Engine-Performance-wise, I'm running a Turbonectics ST, Stillen Catback, and Skunk 2 Plenum Spacer. On my Dyno (on the hottest day this summer), I put down 345 rwhp; I figure 415 hp at the crank. Outta the box, my Turbonetics ST cost me $5451 (not including install, guages, misc., etc).

FYI, by the time you realize the milli-seconds it takes the turbo to spool, you're already plaseterd to your seatback, and don't even realize the spool-time!!!! ...and that's no $#@&!

Good luck - Hope this helps!

Is it safe to use in the manual mode? As far as if your in first take it to like 4000rpm then let off the gas and shift it doesnt hurt it or anything does it?

most importantly...does the blow off sound amazing?

Because for AT's and Turbo's you get a lot of lag - sueprchargers are there from the start. Also, traction is much better on FI's cars if your AT to begin with.

We're running a Vortech GB RIGHT NOW and it ends tonight!!! Look at my FI's Beast goes FI thread in the forced induction section - you'll see my 400WHP and 325TQ dyno - from a LOADED dyno - there.

Vortech SC all the way - and cheaper than the Turbonetics posted here!!!

Every car has a lag with turbos though.....right? Unless you have them timed to spool at low RPMS. Turbos usually dont kick in though until half way through your RPM range in our case about 3500RPM they would spool....thats atleast what i thought. Supercharger since it runs with pulleys it is there for the whole RPM range.

Also, dont you get more torque with a turbo rather than a supercharger?
