Update: Trans cooler and cold side are now on. It’s been a fun process. I need a heater in my garage though that’s for sure. I feel like I am starting to see a light at the end of the tunnel. Need to make my fuel lines next.

 

Keep up the good work I’m doing a similar build with allot of the same parts

 

Awesome truck.

 

Good looking build!! I am starting on a similar and less thought out build lol.

 

Curious why you went with the 1.25 ar? I am part of the Huron group purchase for my NNBS 5.3 RCSB which will be mostly street driven with occasional tracking (once or twice a year.)

At this point, I went with the Huron speed 78/75 with.96 ar because that’s what I was told by a friend to choose.
I have 3:73s and BTR stage 2 cam setup also.

Im new to the turbo world, so I’m looking for recommendations- is there a reason for me to switch to the 1.25ar? Should I change turbos?

I appreciate any input, please educate me so I don’t make a several hundred dollar mistake.

 

depends your power goal. Personally I would do the 1.25, the .96 would be a good option for twins.

 

Would I lose anything by going with the larger 1.25 as opposed to .96 or is there no difference in spool time?

 

we heat my cousins two car garage with propane heaters the type that clamp on the propane bottles one is a dual head other single his garage is not to drafty after a few hours we usually turn off one of the heads on the dual one and work in t shirts with your garage one single head probably all you need single one will run for 10 or 12 hours per tank, every few hours we crack the garage door open for a couple minutes just to make sure we get fresh air in just to be safe

have worked over 9 hours straight with no problems

 

I can only assume there will be a difference in the spool time on the 1.25 vs. the .96. just dont know how much.

You'll need a 4" downpipe with the 1.25 a/r. I want to be in the 700ish hp range. I know the .96 a/r is capable of that I just wanted to try something different. Honestly at the time I bought my turbo, close to 9 months ago, it was very new and not many had ran it yet,

If I was to start over though I think I would run the VS 80mm.

 

there is always going to be a difference. How much is the question. The bigger the ar the more rpm to spool and the more potential it has on topend. Think of AR like fine tuning the turbine wheel size.
