306 Diesel as a trackday car/sleeper???

Hi all-got a theoretical question for you all..........how do you think a 1993 306 XRD would do as a trackday vehicle/sleeper? I would tune the engine but keep the exterior pretty much standard.....or should I just lock it away in the garage and work on keeping it completly standard??,bearing in mind this idea formed in the pub it may never even get off the ground!!.....ideas/insiration/criticisms all greatfully accepted!!

It's possible. Some have tuned an XUD to give silly power outputs (albeit for a while) so it can be done.

Have a look on the 205GTI Drivers forum. Long ago there was someone with a 1.9TD in a 205 that he'd tuned to the max and it was quite a performer...

I like sleepers.

Else that, transplant a 3.0 V6 into the 306. It can be done. Now that would be a sleeper

ohhhh 3.0V6?? I like.......I like a lot!!!!! really like the idea of a bog-standard 306 XRD complete with steel wheels with a tuned or large engine under the bonnet!

Your best bet for a track slag in the first instance is always weight reduction. Strip it out until it's a tin can with a steering wheel. Weight is the enemy, it ruins performance, handling and braking.

Then look at tyres, some R888's would be nice. Then brakes and suspension. Usually more power is last on the list!

I suspect you might have to address the problem of heat soak, particuarly if you upped the boost. Turbo diesels often don't do well on track after the first few laps. My 405 runs 18psi boost and about 110bhp. If I beat on it for a prolonged period I do notice a performance drop off. A front mount intercooler will probably be a must, but that should see you good for 130bhp. Of course, with a 3.0L V6 you wouldn't have problems with heat soak

Thanks for that evilally-the above has given me lots to think about-obviously a seasonsed trackday pro?

Can't claim to be an expert, but I do like my trackdays

It's amazing how fast a low powered car can go stripped out with some decent tyres. If you don't lose the speed in the first place, you don't need a lot of power to make it up. Making your car a second a lap faster by increasing the power will cost a fortune, but you can do a lot of weight reduction for free. Possibly even profit by flogging the bits you don't need on ebay.

I missed one thing off the list, tuition! My Clio is my track bitch, but I've left it practically standard. I've spent any spare money on tuition and it's made all the difference, plus it makes you a better driver on the road. It's hilarious getting past something like an M3 because the bloke driving it will happily spend £30,000 on a car, but won't fork out £30 for a session with an instructor. The added benefit is that your skills are transferable between cars, so it's a lifetime investment

Once agin,you have made some really good points!! instructor session is definatly worth it for £30 and I wouldnt have even thought about!! so,thanks once again!!
