Future Turbo Set Up *opinions*

the turbos good for about 480 reliably anymore than that its going to be pushing it a little to much dropping the lifespan of the turbo itself. 330hp+/- is just a top of my head number, ive never owned a high horsepower car so i thought id start with that. I know ill get power hungry and up the boost the longer i drive the car after its done. i want to get to know the power of the car before i start rolling around with 450 hp at my foot daily. Im just trying to keep my options open with the gt30 . The full build is so i can go high boost when i want to and not have to worry about it, it gives me self assurance. Reliability and response is my main goal with this build. What do you guys think about me overboring the block, worth it? or should i just stay with the stock bore?
Just get a boost controler have it tuned high and just drive on low boost. also keep the stock bore for now

oh maybe i was misinformed then
They are good to around 525hp or so depending on which one you get. The Garrett GT3076R is sold with a 56 trim .60 A/R compressor with a choice of like 3 different A/R's on the turbine housings with an 84 trim turbine wheel.

The HKS GT3037 Pro S has the same 56 trim .60 A/R compressor but comes with a 84 trim .87 A/R turbine which is on the larger side of the choices from Garrett. Plus mine is still slightly different since both housings are extrude honed.

The stock bore is just fine for what you need. Boring only will change torque about 20ft/lbs. The only way to do it correctly is BORE & STROKE. This raises it about 60ft/lbs, a much more worthwhile set.

The one thing unfortunately about your setup is the N1 Crank pulley. For a street car like this, this is really an unnecessary risk. I've run some of the CTR crank pulleys for several years, and for what you're trying to do, it really would be best to go to the OEM pulley. There's no use in the so-called weight savings like you think in an NA car, even if you don't have A/C or P/S.

I'm running an HKS GT3037 Pro S with extrude honed housings at around 500awhp a touch above 70% compressor efficiency.


I would stick with the GT3037R if you plan on working up to the 450 range
True, though there are other turbos that can do similar power w/o the price tag. He may need to ride in some Hondas BEFORE he purchases
