I have a 1993 Fd with a fresh street port motor and all the supporting mods to go with it. My stock twins a starting to leak bad on 12 and 15 pounds of boost. I want a single turbo that will give me a great low end boost with quick spool up, but also want around 450-500 RWHP too. Please give me some suggestions for this set up?? Thanks Chad

 

There are alot of options out there...just search. Also what do you plan on running for boost?

 

T4 GT35R from A-spec or the GR63 from Gotham Racing. Good low end spool, certainly capable of 450 rwhp given c16-supported boost levels.

 

yes, there are a few choices out there. for the best help, i think you need to be a little more specific in the criteria you consider to define "great low end boost with quick spool up" as that's completely subjective. look at A-Spec, Rx7Store and also check with Rich (Goodfella) and Ihor (RotaryExperiment) - [i think i totally butchered their screennames, but they're not hard to find] .


EDIT: oops! there goes Rich (above). should have refreshed my screen before typing my response.

 

I've seen the GR63 kits spool up really fast and streetable.

 

gt35 or aspec 500r. maybe even a t04z

 

I'll weigh in here, 35R for sure... reasonable spool time, good power capabilities, all around great turbo if you're not looking for a dyno queen.

 

it depends, do you actually live in Evansville, or in the area surrounding it?

If you live in evansville, then the gt35r is your best bet, great for stop light to stop light especially if you pull, bebuild and port your motor (Oh and per my mantra go T4 housing only, PM me for my thoughts)

now if you lived in sullivan county where 99% of the cops are total asswipes, then I would suggest one with a little more top end to disabuse them of their ability to box you in...maybe the 500r

god I miss home sometimes....then I think about the jackass cops and just laugh about it

I would have to say that the most impressive street turbo that I have tuned recently was the T04Z. It has the most options for hotsides allowing it to be sized correctly for just about any application, and it is ball bearing .

I have lots of experience tuning both the GT35R (I currently have one on my car) and the 500R, my first choice would be the T04Z over either in this power range of smaller turbos. However the T04R is a slightly less expensive option with decent spool up and good power. There are also many more options depending on budget and this is just in the Garrett turbo family, there are many other manufacturers.

Asking "what is the best turbo?" is just the wrong question, without providing your budget, a list of your actual supporting mods, what you intend to do with the car (street, drag, auto-X, drift), and what boost level you want to run.
