some info on improving your mk2f GT, not a comprehensive post so feel free to add you tips these are the quick power gains • high lift cam 264 / 268 / 270 - the biggest gain is made here. dont forget new tappets • 4 branch manifold and exhaust system - dont go to large or it will cost you power • bigger injectors • better air filter • chipped ecu those probably account for 95% of the gain you can get from the engine the next lot help to pull a few extra horses out for those who really want to put the work in: • skimmed head / port matched with inlet / exhaust • de-wedged ported throttle body • lightened flywheel - not really power but will spin the engine up faster. be warned if the fly is to light the crank will wear its bearings in opposition to porting the inlet you can use a NZ/G40 inlet with smaller holes to fill in the gap created by the highlift cam moving the powerband higher above all refresh the electric and cooling systems to have a solid runner

Hi there I am breaking a red mk2f polo breadvan most parts available collection from Gateshead if interested Thanks Grant

For some of you this will be familiure but for most itll be new. This thread is a time line from my first polo to its end and all the polos ive had along the way and what happened to them Ive had: • black cl coupe • white cl coupe • silver breadvan • blue gt • black gt • black gt

Hey guys, im just looking for some advice really, im picking up a polo gt with the 3f engine soon, however the 5 speed box has lost the 5th gear so i am looking for a syncro ring or where i could find one. im not sure if this is the 084 or the 085 gearbox and because i haven't picked it up yet im not sure what the factory box code is. any help is much appreciated.

There are three types of multipoint injection engine, the G40 is quite easy to spot. This guide is to help you spot a NZ from a GT This is a GT engine (some light modding) This is a NZ engine The NZ is a multipoint version of the AAV engine which was later developed into the GT (3F). • The NZ has the same camshaft as the AAV and was meant to produce the same 55BHP but because of the improved air and fuelling some NZ produce 60+ • The NZ throttle body has a throttle open sensor not a position sensor like the GT • The NZ has the same gearbox as the AAV • The NZ has the same compression ratio as the AAV Electrical items that are different: • Engine loom • Ecu • Distributor • Ignition coil • Throttlebody Electrical items that are the same: • Airflow meter • Temperhature senders • Oil pressure switches • Fuel injectors • Idle stabilisation valve Visible differences: • The distributor has a vacuum hose connecting it to the throttle body • The ignition coil has a 5 pin connector on top • The coolent expansion tank doesn't have a sensor • The NZ has the AAV exhaust manifold The NZ is a capable engine and with the addition of a GT cam has almost identicle power

Got a polo gt coupe in black, really condition bar the hole in the driver sill / floorpan and the 2 inch one in the passenger sill. Interior is almost mint, driver seat has an open seem on top corner. Pretty much std with a single wiper conversion, home brew mount Not had it to long so not given it a full going over, did notice the rad is cracked and the member it sits on is bent so its tapped an curb? Waiting on photobucket to show my pics Really would be nice for it to go whole as its a hardtop gt in black and pretty good condition

I've been getting a fault code on my polo Gt (3F engine code) for the inlet air temperature sensor. Investigating in VWtool shows it reading 20 degrees C lower than ambient air temperature Yesterday, by measuring resistance between pins 1&4 I got 7000ohms, which is too high (according to autodata). Basically does it mean it's goosed? I thought I'd ask as it'll mean replacing the airflow meter, as it's part of he same unit. (attached is sensor vlues from vwtool - the yellow figure is the inlet air temperature) Cheers

Hi, I am doing a rear brake conversion on my Mk2f coupe gt conversion got mk2 golf stub axels Calipers carriers discs and pads, was informed just to use Mk2f handbrake cables wondering how I would connect cable to Calipers, also got a brake bias valve but unsure where to mount, any help would be much appreciated cheers, Ross

Hello Can anyone help me with the following. I stirred my polo from it's Winter slumber yesterday and it was a bit hesitant under acceleration. I put it on my diagnostic leads and got the following codes with VWTool: 523-- ------- Intake air temp sensor (G42) No Signal 518-- ------- Throttle position sensor (G69) No Signal I put a new throttle position sensor on it last year, so it could be the wiring? What would the intake sensor do? I have an induction kit, so does the ECU care? Which data block is it in VWTool? There is one reading -15, does this mean the intake temp sensor is dead?

ive started a swap ..mk2 polo to 3f mpi injection etc the 2 yellow wires for the diagnostics ...the diagram i have shows it going to the interior loom white wire which is heater speed 1 ? doesnt sound right to disable the heater has anyone go a working diagnostic socket on a mk2 swap ...i need pics /help
