Hello all, the names Mike!

im taking the plunge and having a fresh, 46xxx mile '92 gts25 sedan brought over seas for me.

Theres a few things id like to have clarified as I've done a fair bit of searching and either find vague answers, deleted posts, or opposing answers.

First off, the rb25 and re5r that is coming in my car, same engine trans as the r33 or an earlier rendition of the two?

is it possible to do a simple r33 lsd swap into the 32 assuming the trans is the same?

I've also come across a couple threads of some seriously modified auto's to handle massive power. Will a stock trans with an upgraded converter hold on to 300 or so whp?

What does everyone do about tuning when having an auto? I assume in these the ecu/TCU are one unit? Guessing that kills the possibility of using a haltech or some standalone?

last Q! Yes or no, the gtr front bumper fits right up? I've seen both yes and no answers. Some say you need the fenders others say it fits right on the gts.

Firstly Mike, welcome to the SOC you can do certain things to mod your auto to make it handle more power but I'll get a couple of the guys with big power auto's on here involved with your question. There's not much info on big power auto's but I have an auto and is soon to be nicely modded. The first thing to think about before upping the power is as you've asked, the box. Get an additional transmission cooler fitted and look at getting a shift kit fitted.
As said, welcome aboard mate, always good to have another auto owner on the forum

Hello.
welcome to the forum,
The Re5 trans was fitted to the RB25de so i am going to assume you have go the NA version of the engine if its already mated to the trans.

To tune the auto is basic bolt on items (exhaust, de-cat, panel filter) and then use piggy back items for the airflow/fuel and ignition mapping.

I have the 94' rb25det with the re4 trans pulling around the 13.3 mark on the 1/4 mile with no problem and driven daily etc..
