Honesty, by watching various other boards with other applications I've been seeing more oiling problems and they've been Precision units. :?

OBD2 is more that able to be tuned with a suitable piggyback ECU.
The AEM F/IC works on all KAs and has the ability to modify the factory O2 sensors, directly tune the injectors, etc. etc. The FIC can handle some huge injectors with all the options.

Going back to OBD1 isn't needed.

If your concerned about bolts backing out you should look into ones with drilled heads that can be safety wired together. Old t3s used to come with locking tabs from bolt to bolt.

I agree with JGS on this one, if a customer tries to modify a unit and it fails then it's not the manufactures fault. go buy a cheepie or borrow a wastegate for the dyno day and send in your wastegate to get properly serviced.

There is more than one T3 turbine housing and that will be the deciding factor.

The clutch pedal is really soggy... It has one of those clutch dampeners which tend to wear out and leak, so I'm going to replace that first. Then I'll adjust the pedal.

Clutch drag from needing to bypass the dampener? I run a ACT extreme 240SX clutch.

I'd like to see roll speed vs. engine speed :shock: Then again the torque still isn't above 400ft/lbs... torque is what kills.

3rd will take alot of power but I doubt you can hold more than 250WHP in 1st/2nd.
Is your auto box truly "STOCK" ? Regular ATF, std line pressure, etc etc. ?
