Just like the title says, is it worth getting? What are the limitations with it only being a t4? Can I just cut the t4 off and put a t6 on or would it be easier to just put on an adapter plate?

What I am worried about is if I decide to make some big power with a big motor will I be limited on turbo size and end up needing a t6 flange.

"only being a T4" how much power you plan on making?

Yes. I think a better question is "What is the fastest LSx on a T4 flanged turbo?". Unfortunately I don't have the answer but I am also curious.

im pretty sure mighty mouse is on a t-4 88 and he runs high 8's with a heavy car.
id do a t-6 if i was building it from scratch but you can still get it done on a t-4 flange. how fast you want to go like everyone else has been saying will really be your deciding factor

should be able to do high 8's with a t4 and an automatic.

The plan is to put this in a 72 nova with a 434 lsx block and it will be mostly a race car. Very limited street use. 90% of the time it will see track duty but make the very occasional street cruise.

The car weighs 3150 with driver with an iron headed smallblock now. The goal is to run mid to low 8's with the car. Can it be done on a t4 flange turbo with that size of a motor? If so what size turbo on that flange would you recommend?

I believe MightyMouse is the fastest LSX car on a T4 flange 88mm turbo. He has gone 8.7's in a full weight streetcar!

if you have the room, which it sounds like you do, go with a t-6. its not going to be much of a difference in price, so why not? then if you decide to go faster your not re-working the whole kit.
i have a tendence to overbuild but thats also because i do things right lol

That's too much cubes for a t4 flange unless you are going to have more than one. On another note, you can achieve your low 8 sec goal at that race weight with a 6.0 and a T4 turbo for considerably less money.

See, that's my thinking right there. I want to make sure I have what I need to make the goal.

The kit is for sale right now by a member on here. Can't I just redo the crossover pipe and weld on a t6 flange?

That was a thought, but when we want to get wild with it we are limited on turbo and motor size. Eventually we are going to want to go faster and then we would have to redo everything.

Off topic: Did you do anymore to your car and run any faster? I have been watching your build since the beginning.

of course. for the right price, it may make more sense to do it this way since you know everything else fits. it depends on your skills, equipment, etc.
of course, you could always try it on the t-4 setup, then if you dont hit it its time to change to a t-6. lots of ways to skin a cat, i just prefer a chainsaw

If the crossover pipe is atleast 2.5" on each side, you should be able to redo the merge and weld on a T6 provided that it ends up putting the turbo in the right place for ya.

If your goal is to go REALLY fast and use a 6 bolt LSX setup, I would still recommend you rethink the 434. I would use a shorter stroke for reliability and RPMs. Then hang a big thumper out front and look out.

I have been plagued by little bullshit issues that have kept me from improving on my last best time. I accidently bumped my transbrake while grabbing the cigarette lighter the other night while going down the road at 40 MPH. I was under the impression that the Tbrake wasn't supposed to work in 3rd gear. It does. Later that night, I hit it one time and the input shaft ripped out all the splines in the main drum. My buddy had another Th350 laying around and I got the shaft and drum out of that just in time to go to the track. Went out there and now the tbrake doesn't want to hold the car until I get up on the 2 step. I made one bad pass as a result of this and then an 18 yr old kid in a C6 vette decided to go off the end of the track without hitting the brakes. That shut the track down for the night. The following Friday got rained out and now this week, the Alanabi race team rented out the track for the entire week to test their top fuel dragster. Maybe next week.

So maybe I should stick with a 4.00" stroke and a 4.125 bore and go 427 and hang a big turbo out front.

I saw Hunter02ss just went 9.6 in his car with a soft launch and he has a 427 with a 94mm turbo. Is he on a t4 or t6 setup?
