As far as dependability, power (especially torque), and insurance rates... are there any pluses to buying a low pressure turbo, and chipping it, as opposed to buying a T5? Im looking at the 98's or a 00.<br>Thanks!<br>

While I can't claim the same level of experience as JRL, I have to agree with his comments about the LPT low-end torque boost -- I have heard the LPT's have lighter turbines which "spin up" sooner, and I've read Volvo marketing literature that discusses the LPT engines being designed to give more power without shifting the sweet spot too far towards the higher revs. <p>This follows my experience w/ my modded GLT, where I get pretty decent performance at higher revs, but the car is VERY responsive in the quick get-up-to-speed situations. A modded T5 will give you a higher overall horsepower figure, but I love the behavior of my GLT for when I have to avoid idiots that don't understand that physics rule about two objects and the same space. This is purely subjective, but I think my modded 98 GLT has better acceleration than my mother's stock 97 850 T5 -- but hers may end up being more reliable since it's not being pushed as hard. As far as insurance is concerned, I can confirm that rates on both cars are verrrry reasonable. Volvo! <IMG NAME="icon" SRC="http://********************/smile/emthup.gif" BORDER="0"> <p>Might want to consider budgeting for other upgrades. If you care more about handling than raw power, maybe saving a bit of money on a GLT vs a T5 will leave you some extra cash for suspension tweaks. If you're chipping the ECU, IPD recommends upgrading the exhaust as well, to avoid damaging the turbo under heavy boost. (I don't have the technical knowledge to verify that myself, but it sure makes sense)<p>Personally, I'd base your decision on what you find available. Take whichever you can find in the best condition for a good price and go from there. I wager that you'll be happiest upgrading and driving a car in the best starting condition you can find, whichever model it is.<p>One last thought, be forewarned that there is a software update for the later model cars that may wipe the flashed ECU data if it is installed.. my car's too early for it but I remember seeing posts from other users on here regarding the subject. Worth being aware of.
Agree wih everything except the comment about the exhaust.<br>I asked Scott at ipd about an exhaust for the GLT, he said in chipped mod only, he said the stock exhaust was fine, don't waste my money for power alone.<br>If I wanted more sound <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/eek.gif" BORDER="0"> that would be different

I <IMG NAME="icon" SRC="http://********************/smile/emlove.gif" BORDER="0"> the GLT engine. <p>The lag is a fraction of a second at most, and then BOOM, you get peak torque before the torque converter even catches up ... unless you do a brake stand, that is. It kicks in so suddenly you can make your passenger's head go <i>thwap</i> on the headrest. (Tip: most people don't enjoy that)<p>So here's a question. How much more top-end can you wring out of the LPT without spoiling the early boost characteristics, and that swelling bungee-cord-to-the-horizon feeling? And what about sound? (I could listen to a CD of an Audi S1 quattro all day.) <p>I mostly ask because, unlikely as it is (and apologies for going a little off-topic here), I just found out it's possible for me to do something like this to my car...<p><A HREF="http://volvo1800pictures.com/a_ES_73_105/Volvo_1800ES_ES73_105_id_2219.htm" TARGET="_blank">http://volvo1800pictures.com/a...9.htm</A><p>According to the sheet, that's the GLT engine, but it looks like he's claiming 330hp from it.<p> <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/eek.gif" BORDER="0">
Not much, pretty well poops out at about 5300 rpm. You could add a larger turbo but you're stessing the internals (the cylinders to be exact and perhaps the bottom end).<br>Enjoy it with a chip. It's a fun car to drive that way, real fun around town and at lower speeds, under 80 mph. (hint: real time driving most of the time in the US).<br>Look, I'm sure big HP LPT's have been built, but I have no first hand knowledge of them or their longevity, (Ask on Volvospeed <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/rolleyes.gif" BORDER="0"> ).
Oh, wow. I didn't know the GLT Motronic+ chip was (claimed) good for 230hp and 260lb/ft. Not worth doing much more to it than that, is there?<p>Out of curiosity, how much does the 5-cyl turbo weigh?<p>

People have put 15g or 16t turbos into GLT cars with no problem. You just have to have the ECU correctly tuned. There is at least one guy who put an 18t in there on an AWD (which has the internals of a GLT) and he hasn't had problems but he added aquamist, a better intercooler and some other goodies to keep temps down. Bigger than that it seems you need to build up the engine, trans etc etc.<br>Much more info on VS as JRL said.
