Set up:
built 370
wiseco pistons
tick stg 3 turbo cam
arp head/main studs and rod bolts
callies rods
still havent picked the exact head I want yet probably afrs or tfs
roughly 9.5:1 compression pending which heads i choose. could go as low as 9:1

6spd car with a 9" behind it and fully adjustable suspension.

goal: make as close to 1000 whp as possible run mid to low 9s, I do not want to be destined as a roll racer so it must spool and hookup well.

Stumped on which turbo i should run was leaning towards an s480 t6 but im worried about spool times but im also unsure if id be pushing it on a t4 pt88. the car has no a/c space is plentiful and weight is not a concern as i have already done a lot of weight reduction. I have always been a nitrous guy so AR, turbine size, flange size etx is all new to me. Point me in the right direction. Im on a generous budget but thats not to say the i want to go 2-3k on a turbo either

 

 

Because it impossible to get a stick shift carto hook up.

 

He's just saying you're doing it the hard way, especially with a M6 turbo car. An auto will be much easier to launch and keep that turbo loaded. A 1000hp turbo car is the weirdest thing to drive at the track with a 6-speed, I know. Ran 11s in the 150s haha.

My new car has a TH400 and it's pretty damn easy to launch and get down the track, especially with a brake. Way easier than my M6 car.

 

The car will never be an autocar period. Obviously it'll befaster as an auto but it's not what I want

 

*quicker, not faster

 

So basically you're building a redneck supra and not wanting to roll race. Got it.

It took me getting trounced by auto cars at lower power levels before I switched. I kept a manual valve body for the shifting fun and control too.

Now I just let go of the trans brake button and off I go. So easy.

 

The question is not whether or not the OP should convert to an automatic transmission...

He WANTS a manual transmission, and it's HIS, so that really should be the end of any and all debate about transmissions.

The bigger turbo will give you room to grow, at the expense of spool time. The t4 turbo would spool faster and will stay loaded more at your desired power level.

If space is plentiful, are twins an option? It would help with spool time and backpressure. Just something to consider if you haven't already bought a hotside kit.

 

or im building a street car that sees a lot of track time? maybe i want to have fun with my car? maybe i just enjoy drivng a 6 speed? have fun with your auto i couldnt care less.

mid to low 9s may have been a little over zealous but id like to see a 9 second pass which ive seen done plenty with 6 speed cars
was really planning on staying single

 

A friend of mine has a 1200hp turbo camaro with a 6 speed
It runs 10.40s at 150 ish

He also has a fox body with a stock 5.3 and big single turbo
It runs 8.90s with half the power.

6speeds are fun, but frustrating, expensive, and hard to get down the track nearly as fast as an auto


If you have the room id go twins, it'll be more fun on the street, spool faster, and usually support more power

 

i still dont know when i asked if i should swap to an auto.

 

7675, or an 7678, or a 8847.

 

In another thread they made a point that a properly sized single turbo is just as responsive as twins because 8 cylinders are driving it instead of 4 per turbo.
