RedM Posted February 28, 2008 Share Posted February 28, 2008 Not on a Supra of course but for the Pug 306. Apparently When Peugeot designed the 1.9 litre turbo diesel engine, they detuned the performance to build in some 'slack' to allow the engine to have long life if servicing wasnt adhered to. Hence the stock performance was 92 bhp. However, the engine can have the main fuelling upped, the boost pressure upped and the boost fueling upped to increase performance. The turbo's wastegate can also be modified to allow the turbo to kick in sooner improving pickup around 2000 revs. By doing this, the engine can use more fuel decreasing economy but if this increase is not taken advantage of then the economy remains unchanged. and according to people who've had this done they can get about 126bhp from it! You gotta love budget motoring. Link to comment Share on other sites More sharing options...
kieren1234 Posted February 28, 2008 Share Posted February 28, 2008 Wow, if only it was like that with the supra :) Good find. Link to comment Share on other sites More sharing options...
RobSheffield Posted February 28, 2008 Share Posted February 28, 2008 TBH I'm not interested in doing it up or making if faster. It's purpose is to get us to work and wherever we feel like going without costing a fortune in fuel. Most journies that we do aren't at times suitable for speediness.

RedM Posted February 28, 2008 Author Share Posted February 28, 2008 Its a slippery slope son Yeah! I'm going for alloys and under-car neons first! Link to comment Share on other sites More sharing options...
bignum Posted February 28, 2008 Share Posted February 28, 2008 It`ll still be very slow though, dont waste your money, Link to comment Share on other sites More sharing options...
RedM Posted February 28, 2008 Author Share Posted February 28, 2008 It`ll still be very slow though, dont waste your money, All cars are the same speed when there's a speed limit. It's plenty fast enough to handle the daily commute. Link to comment Share on other sites More sharing options...

RobSheffield Posted February 28, 2008 Share Posted February 28, 2008 Way ahead of you, good buddy. Then probably neon washer jets....then undercar neons...you need to make sure that the suspension and brakes can cope with the neons a bit at a time, dont want too much extra power at once. Dont forget to lie the back seat down, that makes them weigh less Link to comment Share on other sites More sharing options...
RedM Posted February 28, 2008 Author Share Posted February 28, 2008 I need the back seat otherwise I'd have no way of carrying my three mates around all the time. Link to comment Share on other sites More sharing options...
RobSheffield Posted February 28, 2008 Share Posted February 28, 2008 I need the back seat otherwise I'd have no way of carrying my three mates around all the time. Thats a tough one, perhaps if they wear baseball caps they wont weigh as much? Link to comment Share on other sites More sharing options...
mplavery Posted February 28, 2008 Share Posted February 28, 2008 i known about it for years, used to work for pug 6 years agao, non of the mechanics recommended it when i found out about it...if you do it the car wont last long ... Link to comment Share on other sites More sharing options...

Matt H Posted February 28, 2008 Share Posted February 28, 2008 Indeed, its always easier to tune normal cars to get that ickle bit more because they are set up for economy rather than performance, swapping economy parts for performance parts always works with them to get that 20bhp more (air filters an exhausts always seem to kick the power up on them) but thats it, once you have tweeked them a little bit thats all your gona get. Tunning a highly tunned car like the supra is different, because your changing performance parts for performance parts... always costs for to get more Link to comment Share on other sites More sharing options...

Tunning a highly tunned car like the supra is different, because your changing performance parts for performance parts... always costs for to get more With all due respect, that's completely the wrong way to look at it. All cars are engineered for a given durability level at a given level of performance. There are no such things as "normal parts" and "performance parts" in OEM-world. There are merely parts that do the job for as long as they are required to do so. It is very rare indeed to find an engine that has been deliberately de-tuned below the performance level that the parts can withstand. That appears to be what happened to the Pug 3.6 1.9tD - it was deliberately de-tuned to allow for durability even when the service schedule was abused, so as long as you look after it you can safely up the power output to what the internals were really designed to take. I agree that the difference in cost to make a change on an engine that is already highly stressed will be greater than on an engine that isn't - i.e. if youalready have sodium cooled valves then uprating those is going to cost a pretty penny, whereas normal valves can be uprated fairly cheaply, but that has little to do with whether the base engine was designed to be economical or sporty. These days, engines tend to be pared down as much as possible to reduce mass and cost, so even a "cooking" engine is relatively highly loaded these days. The statement that economical engines are easier to tune probably applies more and more the older then engine gets. Link to comment Share on other sites More sharing options...
