Since he will be running E85 blend, meth will not be needed since E85 offers cooling properties.

I'm currently running E30 with a custom tune and have zero issues with IAT's

So a stage 1 hpfp or stage 2 should be sufficient for my goals? It'll be a ps2 with some e85 mixture, not going full if I need all the extra fueling upgrades and bits when ~500 is plenty of power for my means. I was mostly confused about why others ran PI or meth often so I had assumed I needed that as well to get the whole thing to run properly.

Yeah, there are some threads specifically on making around 500whp. In summary i believe you will need (and others can chime in).

1. FBO - intercooler (appropriately sized), downpipe, charge pipe, consider TIC also at this point.
2. PS2, also get the inlet (or another turbo option, if desired)
3. Consider an intake, although may not be required (more benefit with upgraded turbo).
4. Stock exhaust should be fine, but similar to intake, might be some small gains once you are on PS2 with higher boost (better flowing exhaust).
5. Stage 2 HPFP to leave yourself some room for fueling if you want to go to higher Emix. Stock LPFP should be fine. No PI or meth "needed". Both add complexity to the setup.
6. DV, such as GFB or turbosmart
7. Custom tune
8. LSD if you want to put down the power. Along with good, sticky tires.
9. Clutch if you are not 8AT. XHP flash if you are 8AT.

Thank you, that breaks it down perfectly, so far that will all be added to my build sheet, only thing I'm curious about is that XHP trans flash. Is it actually more beneficial compared to what Bm3 has for a transmission flash? Also, anything about a TMAP upgrade to read higher boost? Or is stock one sufficient on that as well.

Good question. BM3 will remove torque limits, but XHP is generally regarded as more refined. There are some threads on this and you can read for yourself. In terms of actual performance and longevity, I don't think there is any quantitative data on that, but XHP has been around a lot longer and if you are doing a build of this caliber i would do XHP...

TMAP is another good point. I think you need that if you are going to 21+ psi.

Bigboost 3.3 kit. Throw a fat PTE 6262 on it. Less torque, more whp. Less stress on the bottom end. More spooly noises too.

First I've heard of that kit mentioned, I'll look it up and see what it's about

If I remember correctly its about $3000 for the kit. Everyone on here is big on the PS2 upgrade. While that's great I feel a bigger turbo would be so much better. You want to remove some of the torque, so less cylinder pressure, less heat, less torque, happy bottom end. Not to mention it would pull hard well into the redline and not fall off.

Really just depends on what you want. If you are going for big numbers, highway pulls, runway racing, etc, then yeah, probably go bigger than PS2.

If its a daily where you want it to be responsive and not have to rev it out all the time, you want something like a PS2. The PS2 generally speaking has the longest track record for reliability as well.

Torque is what makes the car "feel" fast usually, while HP wins races. Personally, i would much rather sacrifice some HP to get the torque and responsiveness. But it's personal preference.
