To be honest I think the CT26 as stock is pretty much up to handling 300bhp, anyone correct me if i'm wrong?

An upgrade of injectors is pretty much essential once you start to up the boost more, I got away with 11lbs on the CT26 and stock injectors (although see my other thread for what happened the other day ) and only very occasionally hit fuel cut when really giving it some boot. I believe (again anyone correct if I'm wrong) that Lexus LS400 V8 injectors are a bolt in & allow 100cc extra flow?

300 is my base goal. I'm fine with hitting more. I would like a turbo, that I can turn down to about 10-12 at the start of my build and increase to about 18 as I continue to mod. Oh and how much can a stock headgasket handle?

The stock turbo can do 300bhp all day long. 18psi, however, I doubt it. I'd try and find a slightly bigger one, but that's just me. The headgasket on the 7m can be a wee-bit of a problem, though. I would certainly replace mine if I were going to be running anything past stock boost. As stated before, if you're going to be running higher boost, you need to make sure your engine is up to handling it and you need to upgrade your injectors/intercooler. I extremely recommend getting a new headgasket if you're going to be running that high boost. As to BOVs... I really can't tell you much about them... I'll look around YouTube and see if I can't find something that sounds epic for you. Though, to be honest, a wastegate is safer for your engine. The BOV is more to save your turbo.

Just my two cents here, but I'd try to find one with about a .7-.8 A/R, ball bearing and (external) wastegate. Ball bearing turbos are more durable than journal bearings. That turbo is a fairly good size for street driving, though. It should spool up nice and quick. The only thing that's stopping me from liking it is the internal wastegate and not knowing who makes it.

- Other than that, for the horsepower you're wanting, it should do just fine.

I don't want to sound stupid, but what's the differenct between internal and external wastegate? I see a wastegate on both of them. Is the boost still adjustable? Thanks very. Much

That's the only one that I could find that I actually liked.
Here's hoping?

300WHP can be done with ease, but probably not as easy as you like. It's a commonly repeated recipe but you have to do things right or you might lose the engine.
If you plan to hit 18psi you might as well do a metal gasket now.
Follow this order:
fresh fluids, fix ALL leaks, check/replace all hoses (oil cooler too), check/replace head gasket, check/replace spark plugs & wires, check/replace timing belt, check/replace clutch, check/repair any codes. Then....
3" dp, 3" cat, 3" catback, air filter,
fuel pump, 1UZ KVAFM+ 550's+AFPR,
boost controller+ wideband gauge+ SAFC or something to trim with, intercooler and hard pipe kit,
57Trim Ct-26
stir, tune and serve. Serves 6 cylinders.
Should get you to the target. Although at 18psi you might be a bit higher.

That is asking alot from a stock ct26 don't you think?
Lexus 1UZ injectors are smaller almost 100cc's (remember no turbo). The boosted 1UZ guys are always looking for stock 7MGTE injectors if you want to sell your stockers. I would either get your stock injectors cleaned and re sized or suck it up and get the RC's.
