Ok...let me get this straight. You asked "How much RWHP with these mods???" and got the appropriate responses to such a vague question...you didn't search then either.

Now you ask the same type question about boost. Doward gave you a very good answer in post #4 in the above thread...there's a lot of other things you need to do before you even THINK about increasing HP or boost. You might want to read this:

Not trying to be an arse here, but you need to get a clue ;)

With a ct26... about 15 lbs. But, you'll hit fuel cut @ anywhere from 9-12.. You'll need a lexus afm and 550 CC injectors, or a lexus afm and AFPR/j-tube bypass atleast... Then you can run anywhere from 18-22 lbs.. But without better IC piping/IC.. anything after 15 lbs on a stock turbo is pointless.

A little food for thought: If you go with a better, larger turbo than a CT-26, then the amount of boost you can have without blowing it up will most likely be lower than the CT-26. Boost doesn't mean shit dude, it's how much air the turbo flows at any given boost that counts. You could run your CT to 13 psi before fuel cut (theoretically). Now put on a larger turbo that's better flowing and you may only be able to push 9 psi before fuel cut, make sense?

what would be the best way to bypass fuel cut?

I'm not even answering your question (edit) :3d_frown: . You shouldn't even be doing mods to the car yet. I'll bet 2 grand that you got shit that needs to be fixed on this car or it will seriously fuck up on you, then you'll be needing that 2 grand ;).

starscream's right.

And 'boost' is just resistance to flow. Flow = power. You could run 20 psi and get smoked by someone running only 15 psi.

First, you need to seriously learn to search for yourself. If you honestly think boost = power, then you are in the wrong game, and need to learn.

If you want to learn, then you need to show a WILLINGNESS to do so. Otherwise, you're going to get precisely nowhere.

That said, there is no real answer to your first question.

Best way to bypass FC is a standalone.

Dude if you can learn to use the search button then I see a ban in your future then your stuck with ass holes from the "other forum". If you think we are being rude we are not. dude I have fully built internals and you know what I'm at stock boost. Why? because all i have is an intake on my car as far as parts. before i can put more boost in I have a clutch and exhaust to put on. so lets see I'm looking at close to $4k into my car and running STOCK boost because that's where I'm at now and intell I have the right parts that's where I stay. Fix what's wrong(and what could go wrong) first then get an intake and exhaust then think about uping boost. untel then just deal with what you have the car is fast in stock form as well so take your time and get use to it.

Take that big ugly wrinkly intake pipe off and just run open turbo... then rig your wastegate shut, and you don't even need to buy a boost controller!:icon_bigg







Disclaimer:The above post is complete sarcasm if it wasn't obvious.

Find the search button, many people have given you head starts to links to the maintenance and research that needs to be done before making ANY more power.

my advice is don't look at hp numbers look at torq. numbers because hp is only a mesure of torque at a given rpm. btw in order to get the mhg to work you will be pulling the engine and resurfacing the block and head. also just because the 2.0mm is the biggest doesn't make it the best find out what your compression ratio is going to be you wouldn't want to get a 7:1 cr and have a dog of an engine because you put the wrong mhg in. as I said earlier get an intake and exhaust first then worry about a turbo upgrade.

We'd be rich ;).

Plus, a 2.0mm MHG isn't the largest, there are 3.0mm ones out there ;).

Listen dude. the best thing to start out at once you get this car is to buy a Hose Techniques Silicone hose kit to replace your vacume hoses. Replace all old coolant hoses (there are more hoses than just the two radiator hoses). Check the wire harness for damage and have repaired where necessary. Make sure all sensors are in good operating condition. You can also rebuild your fan clutch as a cheap piece of insurance. check for rotten, dried, cracked intercooler hoses and replace where necessary. Do a compression and leakdown test. and replace ALL fluids in the car (this includes tranny fluid and differential fluid). This should eat up all the extra money you may have left ;).

You don't need a supra. 2.0mm HG lol you Don't even know how much needs to be milled. I don't think you need a Supra nor a TSRM, I think you need basic knowledge and definately a lot more knowledge of turbocharged vehicles. Buy a HONDA and quit posting silly vague ?'s here. Use the search button.

*Edit* Good info in the above post.. Where is Beaver Dam? How far is it from Lexington?
