Long overdue for an update!
Injectors twice, and new Suspension as of October 2019
Back in May I decided to swap the injectors out for a bit of safety margin. After some research, I settled on a set of stock 35 GTR injectors.
At 570cc, and a straight drop in, I pulled the trigger on a set I found on ebay. These went in and it tuned up to the same 255kw, but at much less duty cycle – happy days!
However, the next day I took a trip up to The Bend for a passenger ride day with Openpitlane.com. Cruising on the freeway, I’d get the odd pop out of the exhaust every minute or so. I figured the tune might need adjusting so I carried on.
It got worse. And after 50kms I pulled over an disconnected the O2 sensor. Seemed ok, so I continued on. After the day was finished, the car started up on 4 cylinders and then kicked onto 6 after about 10 seconds – like it had a fouled plug.
This continued for a few days and I realised it wasn’t going to fix itself. Back to Boostworx, where it was diagnosed as a leaky injector. Awesome.
The seller agreed to send me 1 replacement, however I still needed to work out which one as dodgy.
I then stumbled on video from a fellow SAU member - https://www.youtube.com/watch?v=etukUT5SPgw and this one
I had the fake ones of course! I really didn’t think it would be worth someone faking 35 GTR injectors, however I was wrong!
I presented this evidence to the seller, and was issued with a refund. Buyer beware of fake R35 GTR injectors
So fast forward, I ended up getting a set of KPM 550cc injectors with adapter plugs, and swapped them over, touched up the tune a little and was back to 255kw.
In the period between the fake injectors running and putting in the 550’s my fuel pump stopped completely also. So in went a Walbro 255 from Sleeka Spares.
Now the cars a weekender, I decided on switching to E85 as I want to do some track days and like the idea of the safety margin you get with E85.
Should have got the 1000cc injectors earlier in the year, but there is enough in the 550’s to get me to just shy of 280kw with a pretty conservative tune based around the track day usage
Also put some Bilstein suspension in, that I picked up to suit 34 GTT with coilover conversion kit already installed. These were near new, and have tightened up the handling nicely. I used some ISC strut tops to suit the shorter stroke shocks – they work great
