This is how I squeezed everything I could out of my audi 80 1.9 TD 55kw turbocharged engine. First I removed rubber hoses from my actuator and blinded them shut with screws to get as high pressure with everything else stock. with this I went from 0.5 bar to 1.1 bar, what gave me some more...

Just curious if anyone has tried any of the following Inlet Manifolds to improve the flow when tuning their 1.9TD. It looks as if there's quite a large choice of manifolds that will fit the ABL head with slight modifications....e.g. blanking the EGR, and tapping to include a take-off for a boost...

Well, after a six month rebuild she's nearly ready to hit the road... It's Niagara Blue over Pastel White - a tribute to the 71/72 era Microbus, the Transporter's heyday (and my favourite colour scheme)

Here's some 1.9TD data I've collated comparing the performance of the "economy" Caravelle gearbox with the close ratio "van" gearbox (which happens to be what I'm running)... 1.9TD Caravelle and Transporter from August 1992 to 2003 with manual transmission (to keep things "simple" I've only...

Hi, I have now fitted a boost gauge which says that my turbo is giving a reasonable 10PSI but I would like to boost it a bit with the fuel pump/actuator arm mods. I have a recon fuel pump and I'm not sure if it has the security seal thing on the adjuster screw - here is a pic. I tried...

Just bought a 03 plate 2.5 tdi 102 BHP,, and was expecting a big difference in power.to my 1.9 td..this van has been modded with intercooler and fuel pump maxed and turbo maxed..and 5th gear higher ratio conversion.. Yes the 2.5 goes well but it just shows how good you can make a 1.9 go for next...

Just come up against my first (of many probably... ) problems in my 1.9TDi conversion. I have a set of ABL intake and exhaust manifolds to fit to my TDi engine. So as it's raining out I decided to fit them to the TDi engine in preparation for fitting next week. The turbocharger on the ABL...

I hope this isn't an obvious question, being a noob. I just bought an 800-special which is 1.9TD. The engine's been modded to 85bhp but i'm finding it's running out of gearing at the top end. Would like a taller 5th or even taller across all gears. Is there a "kit" i can buy for either...

Hi, I am looking to fit a top mount intercooler to my 1.9TD and it will be easier if I can ditch the EGR valve so I can rotate the inlet pipe through 180 degrees to make the pipe work fit better I know it can be blanked off, so can't see why it just can't be removed altogether with 2 x blanking...

Can anyone throw some light on this? I've studied T4Trick's tech post on this and then my engine and It doesn't look the same. Probably a 2.5/1.9 variation. I have a copper pipe which feeds into a kinda manifold but it looks very different and there is also no square inlet onto the head. Am...

Hi peeps ive been reading abit on fitting a IC on the above & folk on here say it dont seem to make much diffrence,,i should have a new one in post any day now off a Range Rover Sport:cool:,,my question is iam not sure about fitting it now due to "Not Much Difference" the mods ive done have...

How to on how to fit the LDA setup from a 1.9 AAZ or a 1.6 GTD diesel pump onto the bottom end from either an ABL or a 1.9 N/A diesel pump. 1st you need either a 2nd ABL pump, or a 1.9 N/A pump or similar?Along with a GTD pump or late spec AAZ pump. I used a 1.9 N/a pump from a mk3 golf...

Hi folks, Took my van for mot today i was in 2 minds whether to back the fuel off a bit, but decided not to... to see if it would pass the smoke test with it fuelled up.... IT DIDNT... :(... Also failed on ball joint and rack end.... and advisories on rear discs and tinted front...

The idea of the tall top gear is not a new one. Indeed, most VW's in time have had a top gear that goes beyond direct one to one (1:1) drive to the wheels - that is, for every turn of the engine the gearbox turns the final drive once. These higher top gears are known as overdrive ratios. The...

As per the title really - if there isn't one, would someone mind doing one? Along with some explanations on how to make adjustments, what can go wrong, when the 'best' setting is reached, etc......... Sure would be helpful.... I'd do it myself, only I'd be guessing and for tech articles, it...

Just wondering about the tuning advise on here, i.e. the max fuel screw and psi increase on the turbo. Sound like a good idea to me, but my friends all say i'm going to blow the engine up if i fiddle with the turbo. So my question is, i have a P reg (1997) 800 special. It has 125000 on the...

Non Standard Tyre And Wheel Sizes... The following list is of non standard wheel and tyre sizes that some owners have found to work best on their T4’s. Some have reported that bodywork modifications are required with some of the wider combinations (marked*) if the van is lowered - the...

The 02B Gearbox is a beefed up 5-speed gearbox derived from the new cable operated 02A gearbox first found in the '89 Corrado, '88 Passat and Mk2 Golf G60 and grew into the 02Z gearbox found in the 4-cylinder T5 models. Gear selection in the Transporter is relayed by heavy duty rods rather...

Has anyone fitted a front mounted intercooler to their short nose T4, and had it situated behind the grille?? I have seen people mount them below the bumper (especially when they have fitted an aftermarket bumper), but I have seen an intercooler that would fit lovely behind the radiator/lower...
