For the pros and all Evo tuners, I ask for you help! I have a 14 GSR stock block internals and head, I have bolt ons, such as Ets titanium exhaust, Tomie expreem test pipe, AMS wide mouth down pipe,hks intake hks bov, and ams upper and lower intercooler pipes with a 4inch perrin intercooler. I got it tuned by Sean Ivey back in march and made 350awhp with 346trq.....It was fun till now and I just want more.... So i've been looking into the MHI18k vs atp3076r. I want that quick spool up and still be able to reach my goal of 440-450 hp without doing E-85. I hear the MHI is good for 400hp and want more than just that so ive been leaning towards 3076r


I did purchase
map manifold
a fuel pump 300cc I believe
1200cc injectors
ams fuel rail.

Thinking of buying stage 1 cams as well.

Any consideration would help

 

3071 gen 2 will get you what you want.

 

Ill look into 3071, thank you

 

Not to "hijack" your thread but I am in the same boat as you. I have similar stock engine/mods as you (listed below) but looking for guidance on which direction to go. I would rather do it right the first time instead of paying extra for it later down the road. Looking to hit around 500whp

I have been doing some research and have been looking in to the ATP Kits for the GTX3576R and GTX3582R. I have also been trying to find out some numbers/pros/cons on the ETS V3 Twin Scroll Kit if anyone has gone with that and of the turbos you can select if there was 1 better than the other. I was also looking in to the GSC S2 Cams/ Kelford S2 Cams. I know you need to upgrade the Valves and Retainers as well but was wondering if they make a Steel Retainer or are they all Titanium? I heard the Titanium would be a "wear item" that you would have to check every so many miles.

Any help/guidance/recommendations for me and the OP would be greatly appreciated.
