long story short got mr2 couple weeks back,got radiator replaced and its pretty much standard car,and i would like to learn do drift or at least to control the car if its sliding and so as winter is here.Just my main concern is ,is there any extras needed for the standard mr2 for drifting as car is 98y and nothing has been done under it to support the main axle or the engine.So is it safe to try learning drifting in a car park in a 1-2 gear on wet surface,without buckling wheels or doing any damage to joints bearings etc.As today i tried to do couple spins in a pretty big car park on slippery surface in 1 gear and got a bit of a slide other then that the car just spins and straightens out straight away.Asking this because dont want to ruin the engine or the gear box or other underneath parts,as ive no money at the moment to do any modifications might sounds stupid questions but im pretty new to the sports cars,and the mr2 that i have is now my only main car that i got to get by around.

If your looking to learn how to drift, tbh the mr2 isn't the best car to learn in.
I'm not saying you can't drift an mr2, you can... but its mid engine layout makes it more difficult to master than something that has the engine up front and is rwd.

If your determined to drift in an mr2 then there are a few things you would need to consider, mainly your engine, gear box and whether or not your car has an lsd.
Is your car turbo or n/a?
A turbo mr2 would make a much better base car for drifting than an n/a as almost all turbo 2's come equipped with an lsd and the extra power makes it easier to kick the tail out.
I believe some of the later n/a's did come equipped with an lsd but not all, so its definitely something you should check out in your own car.
Ideally you should ensure your car is serviced well and regularly if your drifting in it as it can take its toll on your car quite quickly, it'll also cost you a lot in tyres.

Those are the main things I'd recommend looking at when starting off, if you were to take it further then you may wish to look at uprated suspension set ups, increasing power, uprated differentials etc.
If you would like to get more info on drifting in general, you should look at the online communities, there are a lot of knowledgeable guys on there that can help you out, I'd recommend the forums on...

Hope this is of some help.

Any idea which later NA models came with lsd infamous ? Just the stuff out of Japan id imagine

From what I've read online, I believe it was an optional extra on UK REV 5's, I've seen a number of UK Rev5 N/A's for sale stating that they did infact have this option installed from factory.

best way to test it is to do a wheel spin and if both wheels spin u have an lsd if not its an open diff
