well yeah I know it will work haha but do you think its enough ? Just looking for info on anything I should look out for.
You never placed an actual power number you were after. So as I said, all that above is fine and will work if that’s what you want to do.

400 is doable on a stock GE. Most will tell you not to. If you want to be safe as you said, BARE minimum would be a GTE head gasket and ARP studs.

Then some would make the argument, well if you already went that far you might as well just do rods and pistons. You can see how the rabbit hole can get deeper and deeper.

I’ve decided to do some engine work I’m looking to get some advise but I plan on getting rods, pistons , gte headgasket , bc springs and retainers with arp head studs. I believe this will make my engine handle 10-15 pounds kore safely I’m looking for opinions and advise on anything while I have the engine out!
yeah, get a good trans

400 is doable but the odds of that lasting long are slim to none. the ge is pretty reliable around the 300 mark if left unopened. pass that I noticed it has issues. and damn I feel like a cheap ass. I bought $200 gte pistons/rods and head gasket and maybe $300 to the machine shop for their labor. all in with gaskets I'm under a grand in my engine "build"

Funny thing is trans is actually broken right now just a seal somewhere but I was thinking about getting a ATF speed Stage 2 A650, cheaper than a manual swap and if it’s true then it can hold the power just fine. Some high quality forged rods and pistons with a gte headgasket held down with arp studs should hold up for a long time if you got a healthy engine. I plan on replacing bearings too while I’m in there and anything I can find that needs replaced. I plan on running stock cam unless I have some extra funds at the end.

I welded the fpr instead of plugging it with Jb-weld turned out great , got the pump installed just have to wire it up. Using the Adhesive shown below to be safe with e-85. Just waiting on the submergible hose. Got the transmission removed this weekend, I would really appreciate if anyone has info on if it’s worth to get the our stock A650e autos built or not. Been also thinking about putting in a turbo 400 with a trans brake really just trying to figure out what one is the better option as getting the stock auto built should be plug and play. Still doing research! Got the engine stand out together, just need to borrow a cherry picker and I can start disassembly.

Got the engine pulled, hardest part was the harness you definitely want to remove the intake manifold. Brought two 10 x 1.25 bolts that were used to hook the chain up to when pulling. Broke a few clips but im going to need to figure out what im doing with the harness as it is not in the greatest condition. Going to be cleaning everything and getting everything painted by professionals, I will be documenting my rebuild. I’m hoping that my cylinder walls are in good condition but if not then I will be striping the block and sending it to a machine shop.

Also Decided on a turbo and got it in the mail! VSR “62/62” looks sweet still deciding on sending it to OCD for a t51r mod would love feedback on that one. Also got my 550cc injectors from FMS they look amazing very nicely packed.

T51R mod definitely whines. Seems weird to me to spend $400 on a $600 turbo to make it noisier, but it's your money...

Any reason you chose injectors with the ''denso cushion'' gaskets that face-seal against the manifold rather than using the radium injector seats and injectors with a traditional oring?

Probably won’t do the t51 mod just thought it would be cool and I didn’t see a problem with “denso cushion “

I follow a youtuber called ''two jay'' thats got the sweetest IS300 I've seen. He bought injector dynamics injectors with the denso cushion gasket and had a hard time getting them to not leak air when he pressure tested his manifold...

... which is intuitive with the way that design is meant to create a seal. They rely on the fuel rail bolts forcing the injectors against their bungs sufficiently to seal. Versus a simple oring inside a bore as with most injector arrangements.
