Decat Disappointment but SDI Success!
So yesterday I thought I'd have a go at fitting a decat pipe I bought from ebay and some SDI injectors I'd got from a local scrappy (more on these later).
The first task pretty soon became a no-no. I put the car up on axle stands, sprayed the bolts with PlusGas, and then had at them. After a while of lying on my back, cursing and banging away with a long spanner and a hammer, I had got absolutely nowhere :irked:. I dug out my trusty impact wrench, but due to the access around the exhaust (particularly the way the exhaust bends straight after the cat), I could only really get this on one of the nuts. I undid it anyway, just to prove I could, but came to the conclusion that I wasn't going to get anywhere, so thought I'd move on to the injectors...
I'd looked into buying some SDIs off of ebay, but thought first I'd take a trip to my local scrapyard a few weeks ago. I probably found half a dozen bubble Rovers in total, but only one was a diesel. Amazingly the charge pipe had already been removed, so I just undid the fuel lines and the clamps and...bugger, the injectors were stuck in there, rock solid. After wiggling with a spanner for ages, I managed to get ONE out. The others didn't even want to wiggle. So I gave up and went home. This did however convince me to buy a slide hammer/injector puller in case I had similar issues with my own injectors...
By the time I'd got around to buying an injector puller (this one), a few weeks had passed, so I headed over to the scrappy again, hoping some more diesels had turned up. They hadn't, but imagine my delight when I saw the car I'd originally tried to scavenge was still there, and the injector I'd managed to get out was still lying on top of the engine where I'd left it! :D A whole FIVE minutes later my new injector puller had proved its worth and I had 4 somewhat rusty SDI injectors in my hands.
Fitting them yesterday was a breeze. I didn't need the puller to get mine out, they slid out beautifully by hand, and everything went back together without a hitch. I've only got a large torque wrench which doesn't go down below 40Nm, so I guess-timated how tight to do the clamps, and must've been ok because she fired up without any signs of leakage. A little rough for 30 seconds or so, and then settled down fine. A quick spin showed boost was at 17.2psi, so I tweaked the actuator (easier said than done, engine bay was a tad warm and the knurled adjuster was bloomin' stiff) and checked the boost again: 18.5psi. Time restraints meant I left it there, and after the 40-mile drive to work this morning I can safely say there is a noticeable improvement! A little smoke at times under acceleration, but not too much.
So yeah, a little disappointed I couldn't get the cat off, but definitely a success story for the SDIs!
Oh, and I left out the best bit, how much the scrappy charged me for the injectors...£5.:smug_git:
Wouldn't have known about this upgrade or how to do it without the guides and advice on here, so thanks!
