Which turbo is best?
 

Hey, I've got an 87 turbo and I'm looking to do a couple mods. I am wondering what turbo is best suited for it. I am looking for 12-18 lbs of boost. I'm also going to do a couple other mods, exhaust, filter, possibly bigger injectors and intercooler. Thanks

depends on what you want to spend.
driftmotion 57 trim fits my needs.. MP 67 may fit yours. its about who wants to spend the most and has an engine capable of handling that many lbs.

Set a horsepower goal and I can try and help you out with that.

These shouldn't be optional for 18psi. Make sure engine health and maintenance are current first to be sure the engine (and car) is up to handling the upgrades. You really need a target HP number for anyone to suggest any upgrades.

A target horsepower just helps select a proper turbo that wouldn't produce too much lag. You also have to pick one that can handle that amount of power.

And I completely agree with you, Supracabras. If you're running that much boost, you need to upgrade your injectors and intercooler.

I would like to get about 300hp to start with. Could I also get some recomindation on a bov. I like the classic, pshhh, not the wistel kind. I like the greddy rs. Anyone have. Any recomendations?

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 :wtc: ) 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.

Any suggestios on turbos now? Also id like it to be a fairly direct bolt on.
