What turbo do I want for these situations?

Situation 1:
I want a turbo that will spool faster than stock but still move the same CFM or more.

Situation 2:
I want a turbo that will spool as little as possible slower than stock but give a noticeable bump in CFM.

Situaton 3:
I want a turbo that flows a significant increase in CFM at a sacrifice in spool up time.

Situation 4:
I want a turbo that makes mad high RPM power with no regard for spool up.


All situations hold the motor to the stock 2 liter displacement. It is recognized that a stroker kit will spool anything faster. Please hold "all else equal."

 

What HP goals do you have in mind? The bigger the turbo = greater the lag. Ya, there are few exceptions that off set the lag a bit.

 

BR440 seems like a good choice for #2. solid 40-50hp bump over stock turbo with very very small increase in spoolup. Figuring an "all else equal" situation where this turbo is put on on top of a well tuned stock turbo, I feel this turbo should be worth about half a second at the dragstrip.

I would also like see this "all else equal" car has basicly all the bolt-on parts.
Full exhuast
fuel pump, injectors
ecu tuning or standalone
FMIC, piping , bov upgrade
Clutch
Camshafts

Doing a turbo upgrade before those parts is not cost efficient.

 

Right, I agree that the bolt ons should be in place.

Bahamut, I am not asking this for my purchase needs. I am putting this out there to get a discussion going regarding different turbos and what they do. I, along with a lot of other people, know how to create more airflow and understand the basic principles of making power. That is not what this thread is about. It's about turbo differences hopefully relating to the above situations.

Also, I would prefer to stay away from tuner packages as much as just concentrating on discussion regarding strictly the turbo, ie. housings, wheels, etc. T3/T4, Garret, hybrids, etc etc. Thanks!

 

1. Don't know which turbo can give you quicker spool. Perhaps 10.5 hotside and cams, which you already have.

2. Possibly Buschur Racing's upcoming 20G which wil probaly replace or improve upon the BR440 at less cost.

3. GT30 and all it's variants

4. GT35R, but the spool problems can be somewhat negated with an equal length header
Lastly, I've got to believe Malibu Jack and others can provide better solutions and better options to #1.

 

# 1 10.5 hotside with TI wheel - ever so slight gain over stock

#2 BR440

#3 GT 3037 S or GT 2835

#4 GT35 R

 

AMS GT35R. Period.

How else can you get spool up nearly identical to stock, and over 400whp (Dyno Dynamics) on pump gas?

 

The spool upon a GT35 is far from stock and without the proper supporting mods you would have a very narrow power band

 

A GT30R/3052 with equal length manifold is a nice set up for a more stock like spool.

 

I'm a little perplexed as to how you feel like this is the answer to all four questions. Go to the Garrett catalogue and it clearly shows that what you are stating is quite far from accurate. There is not a tuner in the country that has published stock like (or better) spool with the GT35R, or for that matter with the GT30.

 

For Situations 1 AND 2 I would suggest the Evo400 set up that they rave about on the MLR. Too bad the USD is rather weak against the British Pound.

 

I've just seen a video of the FQ400 against a Lamborgini that at the end of the video in top gear at 30mph the Evo gets rolled by a 1.6L N/A Fiat. So I doubt that turbo is the answer.

 

That's largely due to the fact they were attempting that acceleration run in 6th gear.

 

Situlation 1:
TME turbo with TD06 intake side.

Situlation 2:
HKS GT 2835 or Kansai GT2835 Pro S/Normal version

Situlation 3:
HKS GT 3037S,T67 25G,HKS Kansai GT3240,GT 3040S/GT 3037S,Apex'i RX6

Situlation 4:
HKS T04Z,AMS/RNR GT35R

 

Yes, you are right and I stated that in my post(a.k.a. top gear). I was responding to an earlier post where they thought that it would be a great turbo for the first two scenarios. Besides, even if it was in 6th gear, they ran for over 1.5 miles and still could not catch the Fiat. I think it's a great car with super power, but it does not fit the bill as a "spool better than stock" turbo.
