why??? the more boost you run the smaller the gate you need,

im running a 42mm gate on my car and have no problems at all,

I would get upgraded plugs, spark plug wires, and an ignition amplifier so you don't misfire at higher boost

Werd, I'd like a little explanation on the turbo as well.

1) Im around 10k with motor and everything, but im doin all the labor myself

2) I have all the plugs and plug wires of course, and with the haltec the stock coils should be fine... but im not positive need to do more research (opinions welcome)

3) The T-88 is originally off a unamed pro drag civic (hint: Miles). The turbo isn't avaliable to the public it's a greddy sponsership turbo. I got it for about $1200 and had it rebuilt and balanced by a local disel shop. The bearings took forever to get.

Keep the opinions coming though....

they are also too big internally, and will yield slow spool times due to low velocity.

Yes. they suck ***.

I bet that high internal volume means lots of top end flow. The most important thing about your engine/turbo combo is your engine. What exactly is "built"? Is it race clearanced? Are you running the 8.5:1 comp pistons? Is your engine BRIDGEPORTED because you'll be needing to rev to at least 9k to make use of this turbo and run 22+ psi to really be in the compressors efficiency range (CFM wise).

More info!

Couple things. Your wrong about the wastegate and more boost. Don't know where you got that info. Your going to need atleast a 50mm wastegate if you plan on running more than one bar of boost. And if you don't, you should sell the turbo because its meant for alot more than one bar and under.
As far as ignition goes. Up to 20psi on a Haltech and stock coils is fine. I've run up to 28lbs with stock coils and no DLI. Not saying a DLI wouldn't help though.

whoops i meant the rotors. The ones from TII FCs. Why would you need a bigger wastegate to run more boost? More is asked of a wastegate to be able to maintain low boost pressure on a high revving engine because more exhaust gas has to flow through it. Is there something youre not telling us ernieT?

If you have a small wastegate and a larger turbo you can overboost big time. Seen it happen on the dyno with Demetrios. You'll need a larger wastegate to compensate for more airflow. Your thinking is backwards on the subject. Bigger turbo=bigger wastegate.
And I'll ask Miles when I see him at MIR for the Battle of the Imports race, about this BB turbo because if they don't offer it to the public they arn't going to make a one off. They would only short change themselves.

Only if your turbine housing/wheel combo is sized this way. IE: small for the flow range offered by the compressor side.

Which on most turbos, is the case !

If on the other hand it's balanced to the top end then 45mm gate is more than enough

Ask Miles about the turbo he sold it to my friend Dominic about a year ago for his drag GSX and he bolted it on for a few weeks and then took it off. I doubt highly that there is only one turbo like this one. I imagine that most greddy sponsored cars have this option in the T-88 or T-78 and greddy would do it for the increased flow rates and when thier car makes massive power they say its the same turbo that they sell. Which would make sense right?

Also Dave at KD has two motors of mine. One that was is the REW version with TII FC rotors and rotor housings and a stock 94. The both had busted seals I told Dave to build the one motor out of both of them so im not sure if he used the rotors out of the TII motor or not. But it's your basic build: oil and coolant porting along with a large street port and 3mm seals other then that i havent talked to him to see what other little things he might have done to the motor. I just told him my setup and said built it.

I think you will have to be running methanol or water injection or C16 to take advantage of the T88.

I don't think so i've read up on many setups and it seems with most T-88 setups you can accomplish full boost before 4,500rpm (depending on the amount of boost of course) if it's tuned correctly. The only way to find out is the process of trial and error unfortunatly. We'll see how the setup works and if it doesnt have everything i need for anyother setup so ill just sell the turbo and buy a different one.

Running methanol or water injection has nothing to do with boost threshold. I was saying that if you want to be in the efficiency range of the compressor wheel for the T88, you will need to run high boost (hence the methanol or water injection) or rev very high (bridgeport!)

woah, what is the compressor efficiency range of a t78? Duh the same as a t88.
turbine / compressor
t78 = tdo7 / tdo8
t88 = tdo8 / tdo8

Think before you speak! especially when you don't have a clue what you are talking about!

Its not like I'm ignorant about turbos in general. So I assumed that the T88 had a larger compressor AND turbine than the T78. It doesnt mean I dont have a clue what I'm talking about.

Come on we're all learning here.

I wasnt making inflammatory comments so perhaps i couldve been shown a bit more leniency?
