Romans 2005 Toyota Echo

Yes I believe I just said that. Also yes you can remove the valves from a lot of modern engines by hand. Far easier than mucking about with a spring compressor that usually never fits anywhere anyway

Ahh good point!

I wonder if regular 1nz ones will fit. 

Oh back on this, EGR generally isn't harmful on petrol engines and you can play around with it to improve economy if you need an excuse to make more graphs.

Minimising blowby and feeding it into a catch can will keep your pistons clean far better than ditching the EGR.

@Roman is the head still off the engine? If it is it is more cost effective to machine the clearance off the top of the valve and use the buckets you have already.

When you need more clearance that is.

Yeah the head is still off.

But im not pulling valves back out, too much of a mish with the stiff valve springs.

Will just get them measured up first, might be a non issue.

Yeah a few cam swaps I have messed with on bucket setups you bang them in and magically it all works out fine measurement wise. I don't know much about cams but I would guess that good aftermarket ones have base circles similar enough to stock that it stays in spec :scratch:

Yeah you'd hope so right! 

Cam regrinds where it's a reduced base circle are kind of in that purgatory of cost effectiveness, if you end up needing to replace every single bucket or shim.

You'd hope you dont need to do the same for a brand new cam.

Are these single piece buckets? I have a container of over shims /inserts to suit 4age/1ggte (somewhere) 

 

When I measured mine up I found that using the smallest shim to feeler gauge the clearance was easiest, it sucks when you install all buckets and there is zero clearance on some because you don't know how much smaller to go..

The next shape along (ncp91) has a non ps rack because electrically assisted steering column.

Theres no electric PS from this generation (apart from Prius).

But I think it runs the pump from the higher voltage battery not 12v.

Hmmm but maybe its worth checking.

There are poverty spec echos with non PS racks but ive never come across one before.

People have put the electric assist motors into KP starlets. Legend has it that the same steering column joints/splines have been in use for over 40 years

I've pulled the throttles off the car to mock up on here.
Then reverted Echo to standard manifold which is a bit more WOF friendly, even if it's technically legal with throttles on currently.

Also thanks to the excellent dude Matt Gill I've got some 2ZZ injectors on the way. So that's most of the puzzle pieces solved!

The main task left to figure out has been the alternator bracket, which has resulted in some head scratching and a few different attempts at finding somewhere for it to sit. 
Settled on this, which is very low down bolting onto bottom of the sump.
Ideally I didnt want to have the mounting points that far down the engine, but I think it'll be alright.

Then the worlds shittiest assortment of accessories as a tensioner. I might improve on this, but if it works probably not haha.

I dont have the skills or materials or tools to make a proper version of the bracket from aluminium, so I was hoping in someone in Waikato might be able to help?
Here's some more specific details if anyone can.
