A couple of questions for 240sx LS1 guys...

[wajouba]

Hey everyone, Im about to finish my LS1 240sx build, and Im missing on a few points...

What did u use to cool down ur transmission? cause my radiator has a cooling place fore the transmission (BMW Radiator) but I've heard bad things about it, and an external one should be done, but my problem, non are exsitant in my country I should get one from abraod, should I wait, or can I use the one on the radiator for a while? (I have a 4l60e on my S13)

About the oxygen sensors, I have no cats and nothing on my car, what should I do? what sensors did u use? Simulators? and from where did u buy them? any DIY thread on these? (is anyone running without them?)

I only use the front O2 sensors. Origionally I had a mail tuned ECU and had them ellimiated. So the sire are just capped off at the ECU. But your need to tune the ECU anyhow to ellimate the VATS system so do it then. And then have them clear whatever else you dont use.

TCSAC relaysFuel tank pressure maybe

I had a lot of them elliminated. Its all about what you use and dont.

I also use an auto trans but I use an old school TH but I use a transmission cooler external to the radiator. And its mounted to the front of the center rad support beam. I got mine cheap like 50 US but its rated for a dielsel thay can tow up to 30,000 lbs. You'll have to pay shipping but its worth it. Cooling through the radiator will cool the fluid to very warm at best.

You could always ruturn from the trans to the radiator, then to an external cooler, and then back to feed.
