What output/ power levels could be achieved by moving up to the t4?
This is going in a 84mm 10:1 compression B18c1 motor. 600 HP is the goal.
Is a t4 necessary?
Going to use a custom equal length manifold. Will lag be a problem?

 

is this going to be a street car? I don't know if anyone has made 600whp yet with an sc61, you may want to consider an SC63 or PT67 depending on the car's usage.

 

Going to start off as a street car. Needs to have a/c and p/s. Will definitely end up as a race car. That's why I am considering a t4 based turbo setup. The manifold will be $$$$. I don't want to have to get another one. Bought and sold too many cars. This one will be a keeper.

 

This is going to start off as a street car with a/c and p/s. It will definitely end up as a race car. I will be getting a custom ss equal length manifold done. That's why I am contemplating a t4. I don't want to spend a lot of money on a manifold twice. Been through this too many times with other cars. I want a platform that will satisfy me for time to come. The car will probably be driven 3-4 days a week, but not exclusively. I have another car.

 

I think you need something bigger than the SC61.
I'd say T4, but contact motormatrix, he can help you out.

 

PM Arturbo, he can point you in the right direction

 

When's the completion date?

 

The most whp Ive seen on the sC61 with a 76 trim T350 is 530whp by hybrid 901. Brian Ballard ran a 146mph with his SC61 turbo'd CRX T4. I dont know what turbine wheel he is using.

if you have anymore questions either me or Motormatrix can help you out.

I will be trying to make 600+ here very shortly on my T4 SC61 .70 A/R T04S compressor .81 A/R T housing P trim...my setup is similiar except I am running 83mm bore and my block is stroked.

I think to make 600whp in a SC61 you'll need about 32-35psi, which I intend to run but I dont think I'll get 600whp.

Now, I dont know how much power Brian Ballard is making, but the most Ive seen on a T3 SC61 with T04E housing is 530whp at 24psi. Same exact turbo but with a T04S and slightly lower displacement made 520whp at 24psi but with a T04S.

I would really like to see 600whp out of it but I dont think its possible.

We'll isn't that turbo efficient up to 30 something pounds? Also what's the diference between the S housing and the E housing? I was told with an E housing I could still use my intake pipe off my DRAG kit, where an S housing would be too big. If that's true, how much gain is there between the two?
