Brisbane engine builder/machinist recommendations

Do a full GRB STi Spec C motor, no point using the inefficient EJ20y heads when the GRB Spec C inlet ports are the biggest ports on an EJ ever

This would be nice I know, haven't found one easily and I'm on a rough time limit by christmas. I'm more in the mindset of reliability than power at the moment, so the new engine seems a better option to me than a used grb sti. It is tempting though, i might have another look into it now. Only reason I'm using the 207 block is because it's about $1k cheaper than an ej20y/x block and cheaper than rebuilding my current block forged.

And better than both those options

Ok you've twisting my arm haha, I'll do some calculations and look into available grb motors more. Thanks for your input.

No I meant the ej207 short block is your best bet.

Pretty much set on the short block 207 now.

Just looking at turbo options now. Car has almost 200k on it now so the stock vf38 is pretty tired anyway, turbines aren't rubbing on housing but a slight to reasonable amount of side to side movement, is it true that this is acceptable and will get taken up when oil pressure is in the bearing? No end float that i can feel.

It just seems like a good time to upgrade since I will need a tune anyway and the cars power tapered off way too early in the rev range before. A little scared of slight performance loss from the lower compression of the 207 block I'm going to put in too.

It's starting to stretch the money I had aside for this impromptu engine failure but I'm pretty keen to either replace or rebuild with a vf34 core. The goal would be attempting to just go a little bigger so it's still good on the street and hopefully wouldn't require swapping injectors etc. (snowball effect starting haha)
Basically just starting to see what turbo's are available, TD04 doesn't seem like a reasonable upgrade so any other turbo I'll need the piping to suit or see if a welding shop could put new flanges on my exhaust.
Or rebuild my vf38 with a 34 core for around 2k.

2 years of no mods but unfortunately the bug is biting me again haha

Lower comp means bugger all in a 2.0 litre for off boost performance. Just allows more boost and timing safely. The timing increase you can run will make up for the static compression drop.

I personally wouldn't bother with vf34 internals on vf38. For similar money, just get a good second hand twin scroll turbo from jdm Sti and twin scroll factory headers off the same car.

There are multiple variants of the twin scroll turbos. vf36/37/43/44/49/53/55/56. Go the vf49/56 if you can. Kris from rising run Subaru is your man in this regard.

This will make 240-250kw atw on 23-24psi on 98. Closer to 280 on eflex / e85.

Will obviously need injectors and pump to do this sort of power too.
