...Try a replacement panel filter.

17th October 2007, 14:39

Full exhaust system?

fit some uprated spark plugs

Weight loss - everything bar the drivers seat & steering wheel!

Good advice that.

17th October 2007, 15:01

what about the gear stick mate ? lol

17th October 2007, 15:11

think Sayer said a panel filter improved it loads.

Whats he gonna do with sparkplugs like?

Weightloss = free untill you star buying composite parts
I remember ads bagering on about a panel filter too

Dont forget things like a proper suspension setup & some decent brakes!

17th October 2007, 15:21

VTS engine?

Sorry ill go now lol

17th October 2007, 15:30

you can increase the fuelling on the fuel injector dude.

another 10-20% more jungle juice in theory... but that should be backed up with an upgrade in breathing mods

ps... i have no idea how to mess around with the fuel injector on the car lol

Lol very helpful

They use Glowplugs, not conventional spark plugs.

Try a Green filter but speed will not overall be increased.

17th October 2007, 16:25

isnt there like a little knob you can turn to add a bit more power?

17th October 2007, 16:33

Get a sporty engine to start with..

17th October 2007, 16:42

Are they turbo diesels?

Nope just a 1.5D no turbo or supercharger (or much performace!!!)

17th October 2007, 23:30

have a look on google for angel tuning im sure they can whack a good amount of bhp on the 1.5d even though its not turbo'd

could be wrong

19th October 2007, 13:00

Strip it

19th October 2007, 13:08

Put an open filter on like a K&N. The exhuast manifolds at the back of the engine so it wont suffer from such a bad heatsoak problem as the petrl burners

19th October 2007, 13:13

...and the engines are thermally more efficient so there is less heat radiated by the engine too

19th October 2007, 20:15

vtr/s engine ? lol

1st July 2010, 00:49

what i woud do since i have a saxo vts model ( not engine ) my engine is also the 1.5d but i'v been looking on various website's for diffrent ways of performance change's.
In holland you have specialisted garage's that custom rebuild your 1.5d to a 1.5td, so basicly adding a turbo, ofc other stuff is required to change aswel since most of your engine isn't build to take the power of a turbo.

also they do it at a fair price's in my eyes

1st July 2010, 00:53

you can't

1st July 2010, 01:32

up the fuelling
uprated fuel pump
panel filter with good cold air feed
decat ?
strip unnecassary weight.

and as i think your foreign im sure theres nutters in your country who can do something with it.
maybe use the turbo off the 306 TD,FMIC, Derv tuning box/remap with all of the above would maybe see you 90-100hp

1st July 2010, 08:19

Turbo. You can use a Bosch turbo type fuel pump.

7th July 2010, 09:34

I'vo got a saxo 1.5D mate and i asked this question about 6 months back when i first got it.

In the end i've put a k&n induction kit with cold air intake feed and a sportex performance exhaust and id sayy it's on par with the 1.1s easy, but tbh i can never seeing it getting the performance of a VTR whatever you do to it.

justtt enjoy the cheapp mpg!! I DO!

7th July 2010, 10:55

Lol, i can't imagine the noise it make with an open cone. It's already atrocious as it is. And indeed, people buy them for low MPG, not speed

Heheh, is it one of those fake VTS' from Belgium ? No point in doing that and going from 55 to 70 BHP (if you're lucky), just buy a real VTS.

7th July 2010, 12:48

I've always wondered if you could fit a HDI engine into a Saxo. Running a HDI 16v engine tuned and mapped to about 190bhp and over 300lb/ft torque would be impressive.

7th July 2010, 12:55

the noise from the open cone aint that impressive tbh lol but it sounds alot better than the stock air box

the exhaust however makes it sound a lot meaner

lol nice 3 year bump!

We fitted B4 Bilstein Dampers and a CG-Lock to our 106 Work Van. These seem an upgrade on the standard van suspension which must be quite soft. The only way to go fast is to not use the brake.
Other than that I really would not bother. Maybe an airfilter will gain a couple of horses. Maybe i'll have an experiment, but I prefer to gain speed slowly to keep the mpg high.

CG-Lock

B4 Damper Kit

7th July 2010, 13:36

make it into a td with a low boost turbo? also a airfilter maybe? apart from that i dont have a clue. drop a rangerover v6 lump in it

7th July 2010, 14:40

Engine remap/chip always works better on diesels

7th July 2010, 15:29

Strip it out completley, remove doors bonnet wings etc, scrap it then buy a VT.

Or strip it, air filter, exhaust system and maybe fiddle with the injection should give you a few extra horses. then maybe if you are willing to put the funds in, change suspension and tyres so it will be quick through the corners as it will never be a rocket in a straight line.

these sound like they will be handy to you

turn a slow car into a slow car with abit more torque

7th July 2010, 15:58

because your car is fuel infection you cannot mess with the amount of fuel sprayed into each cylinder (I dont think anyway).

these tuning boxes will programme the ecu to pump more fluid into a cylinder when its on the combustion stroke just like a ecu remap. if used on a turbo diesel they up the turbo aswell.

The mods I would do are :
tuning box or remap
some stiffer dampers and lowering springs
pipercross panel filter
straight through pipe (if it aint already got one) including de cat
straight through back box with no deadening stuff into it
strip of all un-neccesary weight depending wether you need back seats

then it should walk over a standard 1.1 but if you did this to a 1.1 it will walk over a 1.5d so its your choice

7th July 2010, 16:15

full exhuast strip it ecu remap!

7th July 2010, 17:40

check my saxo 1.5D out

7th July 2010, 18:11

before anything mate, give it a good service! then start to strip it....

Its the other way round. There is no ECU but its just on a reg fuel pump. You can not get it mapped and those boxes will do nothing.

He says its fuel infection so it will need a ecu to know how much fuel to be sprayed into the cylinder based on the amount of air inducted and the amount of throttle you apply so I thought it had to have a ecu I know my freinds has but his is a phase 1

i thought tunning a furio to keep up with vtr's was bad but tuning a diesel to keep up with 1.1's is a new low haha

"how low can you goooo" lol

i tried to get my moped to keep up with ANYTHING else on the road lol

I did get my moped to go quick gilera storm 70cc 25mm carb gianelli exhaust boost bottle oh yes the lot and then I felt like the big dog

went out with my mate in his car and I knew his car would p*ss on my moped I was talkin to him while stopped by the side of him. My moped sounded like a loud fart and I liked it and just revved it for the sound then a aprilla rsv1000 touno pulled up behind give a quick bounce off the rev limiter and started pi*sing himself at this point my balls had shrivvled thats how I learnt my lesson.

The lesson is somethings always quicker so dont show off you stupid cunt lol

18th July 2010, 15:32

then your moped was slow, cuz when i was 16 we modded a watercooled yamaha aerox engine with a 80cc Malossi MHR team, vario and clutch also malossi MHR team, exhaust yasuni c30 and a inner roter also Malossi MHR team.

stripped it and then took it out to the testbench did a nice 23.2 horsepower and the thing was only like 40 - 48kg heavy.

my old car a mazda 1.6 16v coudn't even keep up and we dragged next to a Yamaha R1 in germany and won the sprint. 0-100km/u in 2.5secs

top speed of 165km/u and he got there just over 6.5secs

and btw i have spoken to a garage that dus customs turbo's and shit for the plain diesel. He said it woud be easy to add a turbo to my car, but also sayed i had to change allot more then that, injectors etc, maybe less mpg but more torque

19th July 2010, 10:42

I am ROFL at the people saying remap/chip.

its all totally mechanical, bar the stop solenoid having a 12v ignition live, and needing the glow plugs for a lot of heat to fire up, these engines need no battery juice to run.

its totally mechanical.

I would love to see more detail about any turbo conversions though.
