the 2.0 gti is 180bhp but i dont kniow about the 1.6 gti. a remap would add up to 40bhp. if you also include a magnex backbox and a good induction kit you would have even more.

About a second to 60, and about 8mph top speed, depending on who you believe.

Engine, trim, body trim, wheels, brakes, suspension, interior etc all different.

Getting to 150BHP from a standard 2.0 GTi, which is 137, is not an easy task, simply because the engine doesen't have much more to give. Some headwork, cams, natched inlet and exhaust and a remap may do it, but will cost more than chopping it in against a 180 anyway. A remap alone won't get you 12BHP I'm afraid, though Superchips claim they can give 11 (I'm a little suspicious of that figure).

The standard GTi is to my mind very underrated, with a good strong midrange. I'd give it a top-to-bottom service with top quality lubricants, iridium plugs, and maybe a panel filter. I'd then beef up the front brakes with new standard (or Brembo) discs and the performance pads of your choice, some quality rubber and you'll have a sweeeeeeet little machine with nothing to upset the insurers

A remap would not get your 40bhp extra so dont know where that came from :nono:

The 180's only produce around 165-170bhp anyway, they are quite cheap too from 3.5k upwards which isnt too bad. Cheaper to get that then spend alot on getting the gti138 to 150bhp.

Superchips reckon it's not safe to go beyond another 10ish bHP without some other mods - the OBD management won't trim beyond its mapped fuel/air range, making it liable to run lean and cause damage at high loads if the remapping is taken beyond the extreme. It's already in a fairly high state of tune compared to the original base design, and going for big figures also loses the meaty mid range - you don't get more area under the graph, just different peaks. These guys know their stuff, having extracted 31 BHP from my own engine (although mine as standard is in a lazy state of tune) so I wouldn't disbelieve them. That said, several GTi's in the PSOOC made significantly beyond 180BHP at the wheels in a barometrically corrected dyno, so the 180 claim can be considered pretty fair.

In detail it's a very different engine from the 180 unit, and if it were that easy I'm sure pug would've done that for the 180 and saved themselves a heap of development costs. By the time one has fannied about getting a safe and flexible 150 BHP (a peaky and nasty 150 BHP probably isn't so hard) one could've bought a 180 anyway, and benefitted from the interior, exterior kit and alloys.

As aformentioned, I reckon they're great cars but people just see the headline figures of the 180 and don't give the standard GTi a chance, a bit like the old 1.6 205 GTi. The biggest performance gains for a sensible price are in the tyres and brakes. Good rubber, decent brakes, a tip-top motor fully serviced and on song make these a deceptively swift machine, but a nastily tuned motor on bolloxed tyres and shot brakes is as much fun as a night in the cells with Bubba.
