turbo/supercharging - 318d4n - 06-08-2012
Would anyone be able to tell me what would be involved in turbo/supercharging a 1.6 and the budget needed, I know I could get a gti6 if I just wanted more power but I want it to eventually be a weekend toy
RE: turbo/supercharging - ginge191 - 06-08-2012
a lot of research and reading my friend!

RE: turbo/supercharging - Matt - 06-08-2012
most wont divulge information on the subject. personally id got to 106moaners or saxperience and look at the turbo charged vtr/s and 106 gtis. pretty much the same engine.
give the guys there a couple of pms.

In all honesty, no, he's gave a few "pointers", for example there was no one to tell me where to get some uprated valves? but most has come from:

which has been collated over the past 4 months'ish now

out of the entire tab you find the lube
but yeh, on topic, plenty of people willing to answer questions and point you in the right direction, but not many will write you a guide.

Go steal a Eaton m45 :-) then employ kernow's tactic
RE: turbo/supercharging - Dave - 06-08-2012
depends how long you want your motor to last too... my friend bolted a T25 onto his VTR, and it would eat anything, and he just upped his fuel pressure to compensate... the block only lasted about 6 months because of 10lb of boost though... the pistons and top end seemed to hold up well against the varied AFR surprisingly, it was the bottom end that shat itself purely due to the power he was running. It may be running today if he was stuck with 5 or 7 lb. Dont be afraid of trying things
1.6 blocks can be picked up off the bay for peanuts!
RE: turbo/supercharging - Ruan - 07-08-2012
Just quickly, Ginge, why are you uprating valves.... A standard J4RS head will do 500hp with the correct timing
But anyway, yeah, depending on how you want to do it and what lengths you want to go to... It can be done uber cheap, old T25 welded to the standard manifold... Rising rate FPR, cheap power...
I'd personally go down the 5th injector route, you can get a 5th injector controller for literally naff all, in honesty, if you sat down you could make one yourself, it's proper easy... Either get a standard throttle body and shove it in there, or bolt it into the manifold.... I do wonder if you could bodge an SPI throttle body to fit and get something to control that...
Can be done proper cheap, but you'll usually find that people don't want to do it on the pikey, it ends up costing thousands because they can't be bothered to fix it every 30 seconds, because it was done on the uber bodge.

Becuase the head i'm getting hold off has a couple of bent valves; and the cost for uprated pieces are near identicle to new one's from pug. Seems a safe bet, that's all
RE: turbo/supercharging - Ruan - 07-08-2012
It's just the ballache with having to have extra piston protrusion, make sure they aren't going to contact with overlap...
IMHO anyway.

Probably, it's got the regulator built in ready too, only issue is they're only ~36/38mm bore and the injector is very low impedance for driving.
RE: turbo/supercharging - Toms306 - 07-08-2012
Not sure on the actual 'charging side of things myself....but I do know you're gonna have to uprate a lot of other things, mainly clutch, gearbox, headgasket (the usual weak TU parts) plus brakes and stuff too. Just something to bear in mind if you're trying to work out the budget.

interesting... my turbo project im not upgrading the box, clutch OR headgasket (as such) and using standard brake setup.
...lets see what happens ey
RE: turbo/supercharging - Toms306 - 07-08-2012
You're using a 1.8 aren't you Ginge?
If not.....then the TU's can barely handle their standard power, let alone shoving more through them! Unless you're Ripp and can make lots of strong shiny bits anyway.
RE: turbo/supercharging - Midnightclub - 07-08-2012
The TU boxes are completely different to the 1.8 boxes though IIRC, they do a conversion kit to BE boxes though
RE: turbo/supercharging - mechsman - 07-08-2012
^ yup, MA box on the 106's and saxos. Pretty sure it's the same on the 306 1.6 and below as well. The MA boxes will take a reasonable amount of punishment as long as they aren't subjected to wheelspinning or ridiculous torque loadings. The clutch will probably need uprating though. I also know of someone who turbo'd the 1.5D (TUD5 lump). Apparently it went very well but it would ra*e the clutch in higher gears.
RE: turbo/supercharging - Toms306 - 07-08-2012
Yep you're right, 1.4/1.6 306 also use the MA 'box..........can't even handle 70k's worth of 75bhp in my experience so wouldn't like to be using one on anything with more power lol. The diff seems to be especailly weak on them tbh.
As for the clutch, the standard TU one has really thin/weak spring bits (cant remember thier name) on the clutch cover which definitely don't take take well to full throttle starts, know a few people that have snapped these, even on 1.1s!
RE: turbo/supercharging - Ruan - 07-08-2012
106GTis seem to be OK with standard power... It's only when you put 1.1 boxes on GTis that they have an issue - the "sport" boxes are usually fine... Just use a 106 GTi box.

Yeah, I did that with the last gearbox, then the diff exploded and took it all out....

I did wonder if a GTi/VTS 'box would've been a better option when I was changing mine, as they seem to be stronger, ratios are very different though apparently which is why I kept to the standard lol, kinda wish I'd tried out a different one now though.

Oh dear!
Should've made a shiny diff too......

Be warned, the 106 GTI box has unbelievably low ratios, 4200rpm at 70mph :o
RE: turbo/supercharging - Midnightclub - 07-08-2012
WUT
i thought the 6' was bad
turbo/supercharging - THE_Liam - 07-08-2012
Weirdly enough though on the way to Cornwall I still managed 47mpg....
RE: turbo/supercharging - Ruan - 07-08-2012
You SURE that was an original GTi box and not a 1.1 box? I know the 1.1 box is a really common "upgrade" or mod done to them, 4200rpm is excessively high at 70!!!
VTR box is stupidly long, I know that...

Yeah mate, been in a few and they've all been like that...
RE: turbo/supercharging - kierangent - 31-01-2013
my saxo has done 140000 miles on her original gearbox and that runs with no problems
