All or Nothing: My 3L Turbo Install

I know they are different UIMs all together but since the new one flows more as far as i can tell its worth the look

now that youre getting into boost how useable is the car?

not sure what you are asking me about the UIM. did you mean to type growl?

boosting on side-streets is still quite a rush. i wouldn't say there's a lot of torque steer, but i'm wary of the reduction in reaction time available. i'd say the boost is quite usable, although right now it's not coming on strong until 4000 RPM. i think that's likely due to an exhaust leak i developed.

nope i meant grow. when i rev my motor the middle of the UIM gets 1/4" taller b/c the incress in air pressure is making it expand

thats good to hear, how useable for say autox?

where are the pics Gary? you promised pics........

are you thinking of competing with a turbo? i was thinking today about whether i could compete in your class if i locked open my wastegate so that no boost was achieved. ha! how about that then, the car could compete on a road course as well as a drag strip!

well, my cat must be female, because i haven't noticed any swelling under the hood! seriously, though, I'll look for a swelling next time. a mechanic warned me that the composite upper would not handle more than 14 psi or so. anyone with forced induction had a problem with this yet?

Driving around town today, I found two more things to tweak. First, my A/C has been rendered useless by the air-to-air intercooler. Hopefully the Fall will usher in cooler temperatures here in Hot-lanta. I wonder if there's some way to help the A/C be more effective. Anybody? Secondly, my dash buzzes whenever my engine is hard at work. I think I can reduce such vibrations by firming up my roll restrictors (a.k.a. motor mounts), which are currently stock. I took a trip out to McMaster-Carr to pick up "solid" urethane that should cure in under two hours and withstand 9000 psi. I hope 85D is not too harsh. Pole120 from the CEG used 94A "flexible" urethane.

So, my To Do List now contains a mere seven items:
* Replace MAF and capture data
* Remove, fill, and reinstall roll restrictors
* Install Nautilus rear brake kit
* Install wideband oxygen sensor
* Install gauge pod and gauges
* Install aluminum pedals
* Replace driver's seat leather
* Replace e-brake cable

Pics requested will be posted tonight.

94A is hard as a rock ... 85D should be a good compromise with more flex.

Guys, guys! I just got a wideband! I also ordered that mini-DIN cable to connect the wideband to the Xcal2. Am I now cool enough to join your club?!?

The boost doesn't build until ~3000 RPM and isn't full on until ~4000 RPM. I would think you would want it sooner for autocross. i was given a .60/.63 turbo.

Gary,

All a matter of a simple turbo change....but you'd lose the smooth progressive onset of boost and probably deal with wheelspin like crazy.
If you have a good boost controller then you can run low boost with a different turbo for the lower gears then kick it up when you hit the straights.

Don't get me wrong, Tom. Although Joey told me I was getting a 57 trim, the one I got is probably better for my setup for two reasons. First, I won't get into boost when driving around the city. Second, I can actualize more of the untapped potential of my Buckshot-built motor. I'm just afraid this turbo is gonna have me craving more top end, meaning I'll be upgrading cams, LIM, UIM, TB, and MAF this Spring.

EDIT: I couldn't wait until Spring. MAF upgraded to 90mm!

57 trim and 60 trim are almost the same in terms of spoolup if the exhaust housing is the same. THe 60 trim gives the same low end response with better top end. We've been trying to move away from the 57 trim for this reason.
For faster spool we size the exhaust housing but the 60trim compressor is the best of the T3/4 series.
I assume you have the .63 exhaust?
That should be quite good once you start boosting to 10-12psi. You won't want any more power down low. lol
