Sluggish D22 with Terrano 2.7TD
Hi guys! I had a '52 plate D22 from new until it blew the bottom of the motor off at 75mph! It'd done 157,000 miles and worked hard to be fair! I found that Nissan 1st were doing a Terrano 2.7TD kit and this was put in buy a garage I was contracting to. Unfortunately the debt I got in meant I had to sell the truck; I really missed it and recently bought another one...an '04...with the intercooled 2.7TD swap already done.
Ok, so it's got the required mechanical fuel pump conversion and I'm trying to identify the pump. From info/pics on here I think it's off a 2.5 and similar looking ones on eBay are Rexel manufactured. There's what looks like a square vacuum canister on the top of it with no external pipes. Would this be an atmospheric compensator?
On my previous truck we needed to tap into the top of the intercooler to take a boost pressure hose down to the pump but that is definitely not on this vehicle. I'm told that this would have been to get the pump to fuel harder under turbo boost conditions. If this is right then I don't see that it can be happening with my new truck. Oh...I forgot to mention that it's flatter than a kipper's c*ck accelerating and going up hills!
I've made sure that it's getting full throttle and wound the throttle stop out a touch but that of course wouldn't help the low and mid range. I'm yet to adjust the fuel screw which may help but will need to watch I don't get black smoke.
Any ideas chaps?
Once sorted I'm looking at raising the intercooler to mate with the bonnet scoop seal to take advantage of ram air, this in series with a large front mounted intercooler (researching pipe sizes), fitting a cotton/wire air filter in a more efficient stainless housing with a stainless argon purged, TIG welded intake tract, a bleed screw for the turbo and a mod on the fuel pump...that quite frankly I currently forget what it was!?! The exhaust cat is of course history but ultimately I'll build a freer flowing stainless system. I do fabrication in aluminium and stainless in the aircraft and motorsport industries in case you were wondering!
