Heads from your orginal motor are still ok? So you'll swap them on at a later date?

@Roman made a custom sump for his 4GR, I am sure with your skills you could make your own dry sump. Annoyingly the pumps themselves seem to be the main cost, though I wonder if there is a cost effective pump option around https://www.mr2oc.com/threads/budget-dry-sump-system-brain-storming.683834/ Interesting thread that may also be of interest to Roman too Ebay dry sump pump Aliexpress pump Id probably want to pull apart, check tolerances and reassemble etc before use but they are still a chunk of change Scope creep I don't know how much a aftermarket oil pump for the 2zz goes for and maybe im just keen to see a dry sump project :p @yoeddynzever made a dry sump pump before?

Dry sump?

Sounds like good teething issues and nothing insurmountable. It's pretty much a Lotus now right? 2zz and add lightness

Have you used a timing light on it as well to make sure the timing matches to what the link is saying? I can't remember if your using wasted spark or not but if you are remember that the timing will read double with a digital timing light as its reading it twice (this caught me out in the past) All your sensors are reading and plugged in? its not something silly like the O2 sensor not being calibrated and the target AFR table trying to dump more fuel in? or your cold start enrichment table? If it was me id triple check timing, check all sensors are calibrated/plugged in/ reading as expected and see if that helps. Then if it doesn't make a difference throw a base map at it and adjust that for injectors That should remove a lot of your variables Silly question but have you done a compression test?

Do any of the other 4G9* variants have floating wrist pins? they all seem to be 81mm (minus the 4G94 81.5mm) (hmm quick googling says they are all the same dam) 4G67 pistons are 81.5mm and 21mm wrist pin (also impossible to find) so wouldn't work either Doing some more googling, seems audi/vw the 1.8 has 81mm pistons and a 19mm floating wrist pin could be worth a look? probably be some 2nd hand ones around but new from rock auto is around $250aud plus shipping for 4 and you can buy single ones for around 68aud Audi/VW rod 144x20mm 4G93T are 133.35mm

Stock CA18DET rods should be pretty easy to get yeah? What are the specs of the forged rods for the 4G93T? I am guessing they are designed to work with forged pistons?

Is this before or after its turbocharged for efficiency reasons?

Good afterble consternoon, what do you mean I have no rear licence plate? Dam petrol thief junkies stealing my plate again

I was going to say its time to find the Hybrid version for more compression and then realized the 4GR doesn't a hybrid version 5GR crank for less stroke? https://www.youngstarmotor.com/sale-42301339-steel-material-automobile-engine-crankshaft-for-toyota-5gr.html And some 5GR rods I am guessing to suit the lower stroke :p While I was having a look around, they are in development for the 2GR https://denstoj.com.au/products/2gr-toyota-engine-rocker-retainer-kit-by-denstoj?srsltid=AfmBOorA3rvKUNaD8zbd5PGwaiuHbx6VQzbMclxuEL08FcnIcIKc-o-J They already do an FA20/FB kit https://denstoj.com.au/products/fa20-fb-rocker-retainer-kit?srsltid=AfmBOoqp3gIOVdFmXS5jl8vM456uqwKgQtf4XRqkrwI0kNtDUUw1qWOz And one for the GR corolla/Yaris etc https://denstoj.com.au/products/g16e-gts-yaris-gr-rocker-retainer-kit-by-denstoj?pr_prod_strat=e5_desc&pr_rec_id=a7fc8dd21&pr_rec_pid=7004431941798&pr_ref_pid=7603717374118&pr_seq=uniform Even for the 4G63 :p Edit: Looking closer I don't think that kit solves the problem if the pin is falling out more googling required

Prime opportunity to replace the downpipe and do a cat delete :p

If you track something down in Victoria, I am happy to have stuff shipped to me and then shipped internationally if whoever you go through isn't keen etc just buy me a beer next time im in CHCH :p

There is plenty of Subaru Brumbys over here in Oz, though shipping may be hard

What version of subaru motor is it? Ive always thought a non turbo subaru motor with AVCS ie (EJ204D 140kw, EJ254 123kw but more torque) Or a later model FB25D 137kw (timing chain) or the Direct injection FA20D 153kw or FA24D 174kw along with the Subaru non turbo 6speed modified to run in reverse would be pretty sweet. I know a few of the above numbers can be improved on as well. Turbos are cool but harder to manage coolant temps, and you probably dont need the power in that light a shell
