2g Go Faster
Recipe
Intermission
At this point in the mod
process you have a choice. You can continue to make modification
with the stock turbo in an effort to squeeze every last ounce of
power out of it. Or, you can go the route of a new turbo. By
adding all the other usually goodies, sans turbo, it is possible
to get your car going as fast as 13.4 in the 1/4 mile. But the
cost to get there will be much more than just getting the turbo.
That isn't to say there aren't advantages to doing it this way,
and if you do, then when you do get a new turbo the gains will be
tremendous. But just understand that it will take a lot to get a
T25 into mid 13's, some great driving, and you will be really
pushing the turbo to its limits of both power and reliability.<
I am going to assume you choose
a new turbo for purposes of this build up, BUT, you may perform
any of the following mods with the stock turbo and see gains.
They just won't be as dramatic since we are now nearing the flow
capacity of the stock Garrett T-25 turbo. Obviously if you get a
new turbo and it isn't a stock looking one like the Super60/T28
you will have some issues with warranty work. Of course nothing
says you can't swap the stock turbo back in :)
The other option is to go all
out and get a 20g turbo and try for mid to low 11 second 1/4
miles times. However, if you are going that route you need to
consider that a lot of other supports mods really need to be done
at the same time rather than incrementally. The focus of this
build up is around the Super60 or the 16g. The basics are the
same even for the 20g but the order and grouping become
different. Please consider calling one of the many DSM speed
shops to get more advice on this subject.
Also note that up to this point
the 1/4 mile times have been based on my very own experience and
have all been full weight and PUMP gas. Once we move into the
realm of the turbo charger I am making some educated guesses. At
least until I take my new turbo to the track. Also the times are
more geared for use of Race Gas but we shall see if I am able to
do them with pump gas as well.
