360 GLT vs 1.4 340 GL

Post by Chris_C » 02 Jul 2005 01:08 pm

Right, having now been playing round with both the GLT and Kar for the last week (and around 4/500 miles ish in each, and previously around 40,000miles in the 1.4 ;)), been trying to work out what differences there are between the two. Probably not too fair are Kar is running sweet atm (as ever ;)) and the GLT really does need some tlc (e.g, no spaceman silver tubing between the manifold and airbox, which whenever it breaks on Kar makes the engine stall, teh Jetronic on teh GLT does a damn good job of keeping the engine running, but is a damn lumpy idle, and I'm not watching how much fuel it's drinking)

Most noticable differences are:

Suspension. Ok, so Kar needs new shocks, but the difference between the two is amazing. The GLT feels so comfy to ride in, and doesn't bouncy round anywhere near as much as Kar does. Maybe exagerated because Kars are on the way out, but I think the GLT suspension is well sweet (not sure if it's been replaced, I havn't had it apart yet)

Power Steering. Having a kind of love hate relationship with it -still. Apart from the fact I'm now the master of parralell parking too quickly and sticking the GLT 3 foot from the kerb, it does make putting it where you want it easier, but also means I'm dry steering a lot. On the motorway, just have to remember it's there ;). But will probably have to fit a rack into Kar now (unless in a few hours I hate it again)

Brakes. Ok, so the GLT is a lot heavier, but the brakes are no where near as sharp as Kar's (or Fake's for that matter). People who arn't used to Kar sometimes lock it up, so I could just be being picky, but it's what I'm used to still. Very nearly been in the back of a car stopping at lights in the GLT :oops:

Power. Definately not a fair comparision, as the GLT needs a service, but doesn't feel much more pokey at all, though torque is there at lower revs. Might have to be an on going test on this one.

Goodies. Definately not fair, as Kar was one of the last 300's off the production line (even though they are on G and H plates, Kar's still nigh n two years younger), and was toyed up out the box. But the GLT had everything Kar has, and fogs too, so I guess not bad ;) And theres not too much more they could have put on, other than the taxi meter (which would have come out ;)) and A/C. I think all GLT's had powersteering, which is another plus point for the goodies total whether you like it or not.

Conclusions???
Erm nope, other than my girlfriend who I originally made enquires about the GLT for, as it had power steering and she was more than interested (and those of you who met her at the BKV will agree she was adamently against getting one), ain't getting it yet. I've got a bit attached to the GLT now, dispite that fact it's going to take a bit to get it back up to scratch. Add to the fact that Kar is not going up for sale, ever, means that I might be selling a 1.7 soon.

Now then... did anyone suss out if you can fit that 2.3 head onto a 360??? If I'm keeping the GLT it's gonna have to prove its a higher power car.

Some interesting comparisons there mate! I think with the PAS you'll get used to it having not driven a PAS car for a while. I got in the 360 the other day and was steering too much being used to the 405 without PAS.

Though I also got into the 360 after the 405 and thought the brakes were pretty poo too. But there are a number of factors there, although I know it has new brake fluid, some parts of the rear brakes and pads.

Theres been a few comments about GLT's lumpy idle.. they all seem to be like that! Mine idles evenly regarding maintaining revs.. but it is definitely more lumpy than the carb 360.

Power.. no theres not enough :D Mmm... 2.3 turbo. Though mine feels pretty nippy again after a 92bhp 405, which isn't particularly slow in itself.

Goodies.. your GLT also has a 3rd brake light :P Mine doesn't :(

Lol, I really think a lot of the lumpyness is due to no spaceman tube, surely the injectors need hot air as much as a carb does?

And Kar doesn't have a 'proper' third brake either, though then again it doesn't have the correct pin stripe around the boot so that might have been changed at some point.

Kars brakes are definately better though, and poiwerwise you know what happened when we were at MK, Kar did keep up (just, didn't go that far though). I'm just hoping there will be more power after some service work, then even more power after some 'proper' work!

i'll add my comments

a service will do you good, the glt should cirtainly feel a LOT more pokey, especially above 4k rpm. not all glts had pas, grace didnt iirc, but dougle did.

i think the suspension is just your car.. the glt is heavier and feels more stable - partly due to the pas i think, so less steering feedback,

Re that silver airduct for the hot air intake, don't bother with it - just throw it away and remove the temp flap bit from your airbox.

This will ensure you engine gets only cold air which fuel injection engines love. It is only really neede on carb engines.

Your lumpiness could be due to either the temp flap being stuck in the hot air position so you are getting only warm air from the engine bay, or just that the air intake and throttle body need cleaning.

Cheers mate... was off to get some tomorrow! So how does that work then... the point of the stuff on carbs is so that the petrol isn't to cold (the whole carb icing thing again) why doesn't the injectors suffer similarly?

I like this learning by not spending money approach :)

Your 360 should be noticeably quicker than the 340 1.4. If its not then something's worn out, like fuel pressure regulator or injectors. Before spending money on those, however, just spend an afternoon taking the inlets apart and cleaning everything properly from the throttle plates to the air mass meter. If that doesn't work then you need to start thinking whats going wrong.

The brakes should feel almost as sharp as a 340. The 360s are not THAT much heavier anyway, maybe someone has put cheapo pads on. Would be worth investing in some quality items. I noticed that the new proper pads I put on mine were slightly larger than the old ones, which meant a larger contact area. It also meant rubbish brakes for a week because the new pads had to scrape all the rust off the disks where they hadn't been contacting for ever.

Also, because the 360 inj run less with less manifold vacuum you'll get slightly less help from the servo, but I've never had any trouble stopping in my 360.

I think you really need a drive in a properly working 360 to get the feel of how the engine should feel, cos it should really be a LOT more powerful, after all, it has almost double the bhp.

Oh yeah, also the hot air hose will be needed, cos you'll get icing inside the inlet manifold, but I wouldn't worry about it until the winter time. Its only a problem in cold air on motorway journeys.

When my original 360 was on the road, it had a terrible lumpy idle from cold, and actually lacked power for a good 30 seconds from cold, but once warm, not a problem. My G reg low mileage 360 GLT however is as sweet as a nut, as Pettaw heard the other day, I'd just like to know how to keep it that way, as sadly the GLT's do seem to end up sounding a bit rough from cold later in life. As I understand it, PAS was standard on GLT's from 87, possibly late 86 in the UK though I doubt it.

Volvo master tech I spoke to said it was a known problem and due to carbon build up in the heads. Needed a good de-coking and you were good to go. Of course a good de-coking is a hell of a job to do.

I would start by putting in some forte injector cleaner and also forte gas treatment. Don't use a cheaper brand they don't work. Forte stuff you pay through the nose for, don't expect less than 12 quid a bottle but if anything will work, they will.

Pete's white 360 is very smooth from first startup.

For a good de-coke try this method -

http://forums.turbobricks.com/showthread.php?t=35053

Seafoam isn't available in the Uk as far as I know so use something like 'POWER BOOST' etc according to its instructions, but the water torure treatment really does work.

Foggy tried it on his 360 before the carb and cam install and it really did make a difference, We now need to try it agin after his using the car before the carns were tuned properly as this may have coked it up again on a few pots.

Be sure to read the instructions in the thread VERY CAREFULLY as I'm sure I don't need to point out the dangers of hydrolocking an engine!!!

tried the water method, and it didn't work that well for me, although I probably was a bit conservative with the amounts, cos I didn't want to over water it!

Anyways, by the time I got the engine stripped down there was still a good bit of carbon build up on the valves/pistons. The head was put in a bath by the machine shop and I was chucking the pistons anyway cos they were worn out but maybe it would work for you. Never tried the power boost though.

Thats what you get for burning a disgusting dirty fuel(petrol) if you ran your engine on lpg you would have no carbon build up your oil will always look clean and the inside of your engine would look like a new unsed one.

I must say Dai, when I got my first GLT to run on the road, I was seriously considering the LPG conversion. Came very close, but I was put off by the fact that the Government's tax on the fuel was not set for long, and the rate could easily be jacked up once they'd found enough people had converted, making a £1000 plus conversion an expensive option, if I wasn't then going to save on fuel costs. Also there is nowhere around me to fill up. So that would have been counter productive, driving 30 miles and back just to fill the tank up. Also I couldn't bare to lose the space in the boot, as often I put the seats down for carrying things, with a tank and it's pipework around I wasn't keen. I've seen a converted 2.0 litre GLT and they were dead chuffed. Sounds like to way to go, for many reasons, if only they had some filling stations near me that stocked it and the Goverment promise not to increase the tax.

Sorry for the thread jack!

Thanks for that all, I'll have a play. Granted it does have more power (as driving Kar today definately showed) but I would have though there was a tad more, but when you lot see it, you might see why it's not as it's peak ;) Give it a while, and I'll be kicking your asses down at Mr Pod
