Hi Guys

Bought a Ibiza Gti 1.8 16v a couple of months ago. It seems to be lacking power now and i need to find out the best way to get more oomph out of it.

I know I can get full exhaust system, air filter, chip etc, etc, but which combination is going to give me the best performance increase?

TIA

It depends a great deal on your available budget.

First things you have already mentioned.

Beyond that, a good gas flowed head and some mild(sih) cams would give the 1.8 16v some more mid range punch and a bit more top end. (rough prices as a guide: cams £300-£400 the pair, gas flowed head £550, plus fitting and misc gaskets etc etc)

A rechip/remap to the new spec would be strongly advised to make the most of what you've got.

You should expect to see around 160-170bhp from these mods maybe more if the engine is a good one.

Plenty of people know this engine well in the VW scene if not SEAT. If you have'nt already done so, buy a VW mag like Performance VW and look through the advertisers.

Bill

HELLO! I ALSO HAVE A 1.816V IBIZA
i felt so lonely on me own in here,welcome
i have a 2ltr16v induction kit and samco hose(you need the breather pipes too)i used to run a de cat exhaust but having just put it back on for mot found that little bit more torque lower down and less peak power,you wanna try it?its sat in me shed, may never fit it back on.
robT has a 1.816v but it has been played with and is now a 2ltr on throttle bodies,if you can find one a 9A bottom end from a passat or corrado fits in and gives a great increase in torque,these go for around 3-400 quid,as i said if you can find one.
the 3,4,5th gears on the 1.8 are not very close(this info from robT)and changing these to the same as a mk2 golf gti gives good excellaration i presume without revving the tats of the engine.

mines just covered the 100k mark this weekend and has been far better than any car i've had,its still running very well,but as you say it needs that little bit more,have you altered the brakes /suspension yet?always a good starting piont before any power increase.enuff waffling ,hi and welcom:cheers:

Dont you believe it...........

Best mod on this engine IMO is a 2L conversion and the gearbox mods - then exhaust/filter, head, cams, etc.

Cheers

I know how ya feel Jason! I was starting to feel that way mysel, and thanks for the warm welcome. Thanks to all of u for the info, that should get me started. But what you have to remember is im a girl, I dont know that much about cars! (or im not supposed to!)

"the 3,4,5th gears on the 1.8 are not very close(this info from robT)and changing these to the same as a mk2 golf gti gives good excellaration..."

Good info but what do you mean??? :confused:

The ratios are widely spread which means it takes longer for the engine to accelerate the car through them. ie slower acceleration.

Its an Ok g'box for cruising and being a Grand Tourer, but for best acceleration between gears, it leaves a lot to be desired.

All depends on what you are looking for, and how you want your car to drive etc.

I want more acceleration!!!

So do I get the gearbox modified or do I have to replace it??

RobT had his rebuilt with the different ratios I think. (added a quaife too for good measure :))

Hi

The cheap option is a 16V 020 box from a Mk2 golf GTI - it will be better as it is than the Seat one.Cost perhaps £200-300 fitted.

Further options then involve a gearbox rebuild and at this point you can do what you want, mix and match ratios from VW boxes - I went for a 3.9 CWP and a quaife ATB diff as well. Cost £1200 fitted.

Cheers

Rob

Interestingly, I was pricing up gearboxes for mk2 Golf GTi 16v's a few months ago and they seem to be quite hard to come by - as with so many VAG gearboxes, the diff is the weak link when the retaining rivets making a bid for freedom. I had indicative quotes of around £300 supply only on a box in reasonable condition with a 3 month warranty. Labour quotes for fitting were typically around the £100 mark.

I started doing a bit of ground work on alternative boxes and the 1.3 mk2 Golf 4+E was suggested as an option - four fairly close ratios for good acceleration, with a tall 5th for comfortable cruising. As these boxes typically come out of comparatively underpowered cars, they should typically be in better condition. May be an option worth considering?

8v one will have smaller 20mm input shaft so new clutch will be required

mike at golfnutz said a deisel box is mental in a 16v but tops out at 100mph.probably qute strong too.

so come on new gal,giss a bit of info on yer car(year,miles,colour,spec,):cheers:

couldnt you replace the last couple of gears for longer gearing, say from the 1.8 box or 2.0? makes 100+ acc a bit slower but still achieveable.... just my wee brain going into overdrive!!
also, isnt a diesel box geared for low to mid rpm (where all diesels perform) ummm im gettin lost now!! :eek:

This gearbox stuff sounds too complicated for me!! Think i'll go for the easy stuff (exhaust, induction kit, piper cam etc...)

Stats for my Ibiza Gti 1.8 16v

Red
1996 (N Reg)
59,000 miles
Only modifications (not made by me)
Beesting aerial
additional (shopping trolley) spoiler!

I just bought the car about 8 weeks ago and my first priority is bigger wheels and lowerin it!

59,000 miles !!!i remember it well ,years ago.
can recomend bilstein suspension handles really well,but drops a little more than the staed forty mill on the front,its closer to 60mmm:cheers:

Crikey, a red 1.8 GTi.....that's only the second i know about...has it got the traccy control (i.e. electric pack)?

My freinds has a few mods which seems to make a little difference..

Personally, i thought the stock suspension on the N reg big bumber 1.8 Gti's was pretty damn good for a factory car.

Thanks Jason, bought bilstein lowerin kit (also recommended by guy in shop) at weekend, gets fitted middle of week.

Dormouse, no, no traccy control. And I've not seen many red ones either. The new suspension is more a 'look' and 'feel' enhancement, as in looks good and doesn't feel like im drivin a bus! (and im sure the handlin will improve, corners here I come!!) :D

new gal,springs only or dampers too,i used just springs at first ,then within 12 mths my dampers were shagged,then had to buy new ones and fit them.just wouldn't recommend just springs as you'll end up stripping the suspension in a while and replacing the dampers.

just a thought ,speaking from experiance fit once and forget it:cheers:

Hey Jase, just a note to say my m8 had his fuel filter changed the other day....made quite a bit of difference apparently...seeing as you are up into the 100,000's, wondered if you had changed yours?

NewGal? how many miles on your baby?
