Talking Additional Necessary "Fiddly-Bits" for Hybrid Swap?

I'm about to get cracking on my 2.5 SB hybrid/264 Cams/TD06-20G swap into my '02. What additional "fiddly-bits" will I need to pick up? So far, I've accounted for the following:

Shortblock
2.0L heads
Cams/ valvetrain
Turbo
Wallbro FP (installed)
Stock injectors (modded, cleaned and flow tested)
Head Gaskets, Studs
New Turbo gaskets
New manifold/TGV gaskets (?)
STi Oil pan
STi Oil pump? (different?)
intake/exhaust/bigger TMIC (installed)

Any other parts that I may as well change while I have the engine in pieces?

I was considering fuel rails, but have heard that they're somewhat of a "snake oil" upgrade.

Sorry if this question's been asked before. If anyone remembers a good detailed build link (which covers these parts/this question), that would be cool.

Thanks in advance,
Tony

how about stuff like cam seals, valve cover gaskets, all those other random gaskets you'll have to replace? new oil pump, new water pump... this stuff couldn't hurt. Stronger timing belt (PE). Do tgv deletes while they're off the car anyway?

The pumps will be fine, they are the same. Keep in mind these are still reletively new cars.

I would just change the cam seals and valve cover gaskets. Stock timing belt works great.

Thanks for the input, guys. I was going to do the tgv delete while i was there; doesn't seem very difficult. Cam seals and valve cover gaskets...check!

Thanks,
Tony

seal for the oil pump to block
seal for the oil pick up tube
seal for the oil pan to block
rear main seal
new coolant log o-rings
oil cooler o-ring

Did you figure out what you're going to do about the extra crank vent tube on the top of the block?

flywheel resurfaced?
do you have a clutch alignment tool?
oil
coolant
feeler guages
you'll need some teflon sealant
paint pen(white)

You'll wanna make sure your idlers and pulleys are still in good condition and replace those if necessary.

After looking through my Subaru repair manual, I've circled a bunch of the gaskets to replace. I am not going to swap my oil pan, but will change out my oil pump to an upgraded one. Someone said something about the damage that's done to an oil pump when your bearings are going and I can't help but to agree.

Have parts coming from Gruppe-S in aout 3 weeks. I'm going to strat dismantling the car this weekend. Take everything apart and checked and cleaned (idlers, pulleys included). I have a feeling that I'm going to replace a few things under the hood "while I'm there". The motor has about 85K on it and I could see myself putting in a new water pump, etc.

I need to get started on my TGV splitter removal and may do a (slight) amount of porting on my exhaust manifold... possibly the throttle body as well.

No need for the STi oil pan (so i've heard).

As for tyhe crank vent, I'll probably attach a small tube with a filter on the end to still allow for breathing whille not getting oil everywhere. I've heard of people just capping it with no problems as well.

thanks guys,
Tony
