So, as reported on the Grin thread this little beasty passed an MOT on Monday😄😄
I spent Saturday afternoon generally fettling it for its MOT. We fitted the road wheels to it (Not gold. Boo) and at the same time I checked over everything. I was also trying to work out why the ABS light was on. Turns out I'd nicked a sensor wire whilst grinding off a recalcitrant drop link. It wasn't cut right the way through so I nearly missed it. I've connected it together and put heatshrink over it to keep it clean.
I also took the exhaust back off to chase a few holes that became apparent in the manifold once I'd made up the system. It's a lot better, and good enough to pass a test but there's still some wee holes I'd like to fix. I'd also like to clean up my frankly terrible welding from modifying the manifold especially.
It was running rough, idling with a slight misfire when cold and missing on initial throttle application. i chased air leaks and then put some fresh fuel in it, this seemed to cure it.
Back together and dropped off on Sunday night after a very brief test drive with no EMLs so I was happy.
After a nervous Monday spent mostly checking the MOT checker online i was eventually greeted with this
That'll do me!
Off to pick it up and here she is.
It's tatty but presentable and doesn't hint at being non standard, just the way I like them!
The idle from cold was still an issue but I'd managed to find one potential cause. The MAF housing I'd fitted was a larger diameter than the stock one and this can cause a false reading of how much air is going through it. I had some reducer rings which came with the cone filter so chopped up the smallest one and fitted it, this seems to have cured it.
So, I guess you all want to know if all the hassle was worth it?
Imagine your small sports car which had 140bhp at 6000rpm suddenly had an extra 2000rpm and 50bhp to play with? Well that's exactly what we have here.
The 2zz feels a bit more urgent at lower revs than the 1zz, probably down to the exhaust/filter. Put the foot down and it goes well with the lift kicking in around 6krpm with a noticeable shove and change in exhaust/induction noise and pulling strongly all the way to the 8200rpm redline. It's addictive!
The exhaust isn't too loud for normal driving but put the foot down though and it makes a great noise. Then it hits lift and sounds like an old Escort rallycar with a BDA😲 Having the air filter jammed in the side vent adds to the fun, just open the passenger window for full effect!
Here's a video recorded from the passenger seat. It doesn't do it justice but you get the idea.
It's only done about 40 miles or so between Duncan and I but we're both smitten. Although both have commented that we seem to be arriving at corners a lot quicker than we used to 😁
So, next up is tidy up the exhaust and make sure it's well hung. Also I'll need to refit the heatshield as with the cat in the bay it gets fooking hot in there. There's a couple of EML codes now, this being a Toyota at least one of these is for lambda heater wiring. I'd like to bleed the brakes before we go on track, the rear caliper and discs/pads all round were new about 4 years ago before it was laid up but he feel isn't great. I did forget to try and bed the pads in though which might not have helped...
