200sx Web - Wide Body Nissan S14a

well got some bad news today.... The street wheels i have been using have been sold and i am going to have to return them. I knew it would happen soon and it was nice whilst it lasted but instead of planning and getting a set in advance i haven't so am stuck with just my track wheels now. Now the choice of wheels and price is astounding, i am lost in a sea of choices ATM and looking at champagne tastes on a beer budget.

Ordered new lifters today as a pre-caution to the miss fire issue, thought whilst the head is being worked on it is best to replace the lifters as they have not been replaced ever. Picked them up for $49.95ea from Frsport.com, $57.97 del and also grabbed a new apexi filter whilst i was at it. I thought about doing the rocker arms as well but it was just getting to much money. As it stands i am up for $440 for the valve springs (unigroup ones), the Lifters and also labour of $400 so is an expensive exercise. I really hope this fixes the issue as from here i am about to shove these cams in the bin and go back to what i had before.

Went to eastern creek on friday having taken the day off work to try and solve the alisusive miss fire issue. The hopes were high that we have fixed it with Unigroup having checked over the car and tweaked the tune and it not miss firing on the dyno. I have left late from home and dropped michele off to work but mid way to the track i get a call from James saying it was packed. Said i needed to get here ASAP or fear missing a spot, luckly that was not the case and james picked up the last two garages so we were set. Unpacking i had already set my tyres pressures the night before and all i needed to do was tweak the dampner settings and drive. Unigroup was coming out to work on another customers car and we had organised to book two garages together, he was running late so was not able to hook up the gear before the first session. We were first up and i was last out in the pack, feeling pretty good i took it easy the first lap then started to get stuck into it on the second. Co...

Andrew came around on Monday whilst i have been home sick and installed the sensors, i need to set up the logger to register them now and i can start seeing them.

since fixing the EGR valve the boost pressure has spiked as far as 25psi, i had the boost cut at 25psi so it din't go higher but it looks like the leak has made a difference to the boost pressure and hopefully will make a difference to the miss fire. Planning on going to the eastern creek open day on the 20th May with Unigroup and test it out, need to get some new rear tyres as i have smashed them at the last EC open day.

Ever since changing the fuel pressure from cold i have had to crank it 3 times to get it started. This never happened previously even with the E85. Also you can't put to much throttle in as it will start to stall when cold, even when warm from low down it stutters a little and i think it is because the cold tune and start up has not been fixed since we changed the fuel pressure. Here is a short video showing the start up

After the suggestion from Unigroup that the miss fire problem might be because of a leak in the EGR valve i pulled it all out this weekend. I quickly found the problem and it was in the top section, i could have just plugged this up but i thought even though it has been a big pain to get out that i would take the whole thing out and make up a blanking plate to cover the outlet. It looks to me that this was damaged either when the injectors were installed or when the engine came out as it has severed the hose.  You can see how tight it is in behind and i managed to remove it without taking off the plenum which i was pretty happy about. A little bit of weight removed as well.  Bit messy but i can't actually see the face of the thing and just put heaps of silicone on it to make sure it was sealed up tight.
