Hey everyone. I've given this some thought and I'm strongly leaning towards dropping a turbo into my 850. I was thinking about a T3/T4, but I have a few questions. My main concern is that I'm at around 141K now, and I wanted to know what I will need to do to my motor before I can install a turbo, meaning if I need to rebuild it, along with any other precautions? Also, does anyone have any suggestions for any good FULL turbo kits, preferably T3/T4? Thanks <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/smile.gif" BORDER="0">

Re: Thinking about getting a turbo/ what will need to be done? (steve s)

I figured it would be easier to sell it and get a turbo from the factory, however I've invested a decent amount into this vehicle just for maintenance, and it holds a sentimental value to me, so I'm not much up for selling it. Based on your statement about the rods, I'm assuming a full engine rebuild is my best option?

If you're committed, find a T5 that's wrecked or has a blown tranny, and rebuild THAT motor, and then swap in all the wiring and hardware. That way you're not hacking the wiring and custom fabbing on every single piece of the job. Do a manual swap while you're at it.<p>That way you can still drive your car while you do most of the work, plus then you have a parts car with glass, window motors, switches, interior clips, and all that other little crap that is reeeeeeeally handy to have around.

i understand the sentiment, i've had this car for almost 15 years.<p><TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD><i>Quote, originally posted by <b>LloydDobler</b> »</i></TD></TR><TR><TD CLASS="quote">If you're committed, find a T5 that's wrecked or has a blown tranny, and rebuild THAT motor, and then swap in all the wiring and hardware.

Re: (steve s)

the thing is, my 850 is already a 5-speed so I don't need any tranny swaps or anything. It's a 96 5-speed with 141k, as I mentioned earlier. And I'm glad you understand where I'm coming from with my sentimental atachment. Would it really be that difficult to drop a turbo into my motor? And rods are part of a motor rebuild right? Thanks.

Re: (eurotuner)

Look at it this way. Would you rather swap a tranny or tear apart an engine and rebuild it with new internals with lower compression and stronger rods, buy a new intake mani, exhaust mani, exhaust downpipe, turbo (fab up all the oil lines), intercooler, piping, tuning etc?<p>You can't just drop in a turbo, it's not like a K&N airfilter. <p>Even if you "drop one in", you'll need to replace the clutch, build up the engine if you want to run a T3/T4, custom tune, larger injectors etc etc etc. <p>I'd hate to be one of "them", but just get a T5 and go from there.

We all actually do it every weekend and don't want other people to find out how fun and easy it is.<p><br>Seriously, it's really hard. You need all the engine management and everything, or the car won't know how much fuel to give it, the stock injectors can't give it enough fuel anyway, and it'll constantly be retarding timing to control knock because you have no active boost control. Etc, etc, etc. Unless you're up for custom engine management, which is very cool, but vastly more difficult than the swap I'm talking about.<p>Volvo already did all that engineering for you, it's just waiting for you in the form of a donor car. And when you're done you'd have a very rare '96 T5 Manual.

Doesn't matter you really can't do this without an bottom end rebuild with different pistons and liners.<br>To do it right that you won't blow up your engine, you will be spengding 4-6 grand!<br>(at least)
