relpacement turbos and low end peformance

I see how replacement turbos and such perform on the drags and all out wideopen performance .. but how do they perform on everyday driving.

say the daily commute empty in 35~50 mph suburbia.
how does the garret , h2e and tn do ?

seems like most of my driving is open cruising etc.I assume almost any turbo with a chip will have superior takeoff etc..but then I read complaints about slow spool , low end lag etc. are these worse then stock turbos, or just not as peppy as others.

Re: relpacement turbos and low end peformance

The Garrett is awesome on spoolup and driveability.

I'd say the new Turbonetics will be too.

H2E is probably a little big to expect it to light right up in town.

In my experience the current TN drop in with the 1.0 housing is a tad laggy, never driven one with the .84

Hope that helps

My .84 lit hard with relative ease. Once it was at a pound or 2 and you stepped on it, boost was instant. The new BB should be much better. It should spool much faster.

I'll also add that my stock turbo with 1.0 housing is Turd with a capital T.

Seems like it takes forever to spool.

I can't wait for a ball bearing (of some sort )

Re: relpacement turbos and low end peformance

best bet for quick spool up is a ball bearing of some sort. right now my TN lights quickly, but there is some lag when compared to the stocker..

Re: relpacement turbos and low end peformance

My stock turbo with 1.0 housing spooled pretty darn quick, just slightly slower than the .84 housing. My ATS BB spooled really quick, off idle it was a little lagy, but nothing to cry over. I would look at the new Turbonetics BB or the Garrett BB, they are both better than the factory turbo.

Mike,
You are going to need to judge the reviews, driving history and altitude then compare for your needs.

Myself I love the H2E. The stock turbo spooled faster on the bottom but no one turbo will spool fast yet provide great top end performance and efficiency for every application.

Re: relpacement turbos and low end peformance

I like my Turbonetics .84 too. Mine is an everyday driver and tow's on weekends. It spools quick and works well with my mods. A 1.0 might be better with big sticks, but ask Gregrob about that.. I'm gonna do the BB upgrade when it is available.

Re: relpacement turbos and low end peformance

A big factor in this subject is the level of performance you are actually after. If you are looking for sub 500rwhp, then without a shadow of a doubt, the Garrett GTP38R will do a very good job and is one of the absolute TOUGHEST little bastards around.

Lag......what lag? It does NOT exist with the GTP38R, never has, never will.

I have never had mine to surge on me (when intercooled) and I have run so many different injector combos, you can just take my word, that little guy will not surge, not the one I've got. I don't care what you've got for fuel. Everything between bone stock AD's to BD's and BI's, and I do mean Everything in between.

Once I ran out of air....I simply added another of the GT family, the GT4718.

I am sure that Holset, Turbonetics, HTT, as well as some others make wonderful chargers as well.

My experience in the less than or equal to 500rwhp zone with the GTP38R is somewhat extensive, and has always been extremely positive with regard to that charger.

JHMO.

Good Luck.
