Collin Gyenes has been servicing and constructing quick Volkswagens with Techtonics Tuning for the reason that early Eighties. He’s very acquainted with the MkIV GTI and has some ideas for our readers.
The entire MkIV automobiles are good, however the cream of the crop are those armed with the 1.8-liter turbocharged drivetrain and the two.8-liter naturally aspirated VR6.
When you’re purchasing for a MkIV GTI, you might need to concentrate on the state of the inside. For the primary few years of that technology, the interiors are their weakest hyperlink. They don’t have a tendency to carry up properly to fixed put on and tear.
For the 1.8T automobiles, those made in 2002 and later have the extra fascinating 180-horsepower engine. Likewise, the late-2002 VR6 automobiles will include the 201-horsepower, 24-valve engine somewhat than the 12-valve engine. Each turbo and naturally aspirated engines are good. The turbo makes extra energy with modifications, however the VR6 is a really clean, high-revving engine. You may determine between the 2 merely based mostly on desire.
The 1.8T is an excellent engine, however to make sure dependability it should have common oil and timing belt modifications. The timing belt is greatest modified between 80,000 and 100,000 miles. The plastic cooling flanges must be modified and checked, too.
The VR6, whether or not 12-valve or 24-valve, wants new timing chains about each 130,000 miles. This may be an costly endeavor for a store to finish. The transmission must be pulled to get to the chains.
A few of our favourite hop-ups for the turbocharged engines embody an aftermarket down-pipe and exhaust. These two items can get you as much as 20 extra horsepower. Add an aftermarket ECU and you may see one other 40 to 60 horsepower. An aftermarket diverter valve is one other standard improve.
The VR6 engine additionally advantages from an aftermarket exhaust (7 to 10 horsepower). Cams are one other good improve. Each the 12-valve and 24-valve automobiles profit from a cam setup of both 264/260 levels or 268 levels. This improve can web a 12-valve automotive 10 to 16 horsepower, and a 24-valve automotive can see a few 17-horsepower bump. The 24-valve automobiles get essentially the most out of a 264/260 setup. A software program improve can also be good for about 11 to 16 horsepower.
If you wish to improve your suspension, contemplate A-arm bushings from an R32 in addition to new HD shocks and springs.

On the suspension aspect you’ll be able to put within the Audi TT spindle to get some higher geometry, simply flip the tie rod round. Partsgeek additionally has TT decrease management arms ($88 every!) loaded with the above talked about bushings and moog balljoints. That can achieve some camber adjustability. And if you’re doing all this, it is doubtless that altering the struts is within the plans anyway, and shock! TT struts will match, and in addition present a handy mounting level for the swaybar mount misplaced swapping to the up to date management arms. Simply add a common 18″ ball finish sway bar endlink from white line. (No have to swap to a TT sway bar). If reducing is within the plans, remember that there’s a brief and lengthy model of the bumpstops for the usual and sport automobiles. All GTI brake gear will match, and match beneath 15″ wheels. Bigger rotors will match with TT caliper bracket, however bigger wheels are wanted. The rear finish could be stiffened up on a budget with some springs from the Jetta sedan or wagon.

It introduced us a technology of paint consuming stance bro VW house owners lol.
In reply to TR7 :
Does the decrease management arm change require the TT spindle or can the VW spindle be used with the TT decrease management arm? Could be good to have some adjustment on camber. Thanks!
Unsure i perceive all the hate for the MK4 GTI. I’ve a twentieth anniversary version. I feel it’s a very good automotive. Enjoyable to drive. Much more enjoyable to drive after some OEM+ mods to suspension and engine.
I’ve ridden and pushed in a MK7 GTI. Very good automotive, for certain.

From what I keep in mind, you should use the TT decrease management arm and VW ball joint with the VW spindle. This can achieve you some camber, possibly 1 diploma on its least aggressive setting? You can’t nevertheless use a TT spindle with a TT ball joint and VW management arm. Technically I suppose you can also make it work, however its terrible. The ball joint doesnt actually match and you find yourself with quite a lot of optimistic camber.
