I cant say. All i know is that there was no noticable change after installation, however with the air scoop i actually felt better throttle response. I was sure i wasnt going to notice, but i did.

EDIT: Throttlebody spacer has now been removed from the car, no point in keeping it installed. One more thing that can brake, I felt.

Reviving this thread just for opinions and posterity lol.
So I recently suffered timing chain failure, which took the engine along with it. Ive since decided to go fully forged, CP Carrillo pistons and rods, heavy duty wrist pins and calico coated bearings, simply because Im a masochist and I like being the underdog lol. The car is currently at the engine builders shop, getting ready for the rebuild. Ive purchased an MHI big turbo, VRSF catless down pipe, FTP charge and boost pipes, FTP intake inlet pipe, injen intake and VRSF intercooler. Planning on going with a Cary Jordan custom BM3 tune as well to bring it all together. Assuming I have enough fuel, what do you guys think Ill see rwhp wise with this setup? Will I have enough fuel to max out the MHI turbo? I havent upgraded the fuel system at all, but the LPFP is brand new since the car had a recent LPFP failure and was replaced. Additionally, for those that have gone this route, is there anything else you guys would recommend to do now that the engine is being rebuilt? Goal is around 350-375rwhp, I dont really want to dive into upgrading the fuel system, just want something quick and fun but RELIABLE as well as this will still be my daily driver! |

https://navardituned.com/collections/bmwn20parts also, if you are going balls to the wall, you'll want to have these installed for a bit more lift. A set og 6 for the n55 fit the n20, but you'll only use 4 obviously: https://www.bimmermilvs.com

https://www.bimmerpost.com/forums/sh...php?p=27467237 Car sits the same, but with a TTE400 turbo (specs are the same as pure stage 2) + s63tu injectors. Car can't handle these larger (flow 40% more than stock) injectors with the stock hpfp thus a b58tu HPFP is being installed next week Tuesday. Should be fun to see what's possible on 93 octane. Will post up a dyno for comparison before dabbling with ethanol. Fueling wise I'm not too sure but at 22-24 pounds of boost with the bigger turbo it held, however I'm sure you'll want to max it out at 30 if possible due to forged internals and the rating from Mitsubishi. This should be good information for you: https://www.notion.so/N2x-B4x-HPFP-I...f2cd8b2c0b1038 Navardi has been awesome with everything, he has been doing very good with tuning my car as well. I'd give him a shout and get the car tuned by him from my experience.

Ive heard that going with ARP head studs after 25psi is probably a good idea to avoid head gasket problems as well? Also, did you go with colder plugs or are you still on stock plugs? And so Navardi was the one who tuned the car when it made 330-340rwhp? He does seem to know his stuff and know it well, especially when it comes to forged N20 builds Last edited by FinnF30; 10-02-2021 at 02:11 PM.. |

Tte400 is the same as a pure stage 2. Induser and excuser (spelling and fighting autocorrect lol). You can reach 330-340 on the mhi I'm sure with the higher boost level, but just to be on the safe side the upgrade for the HPFP makes sense. Also if you plan on running e85, you have to run the stock injectors at a higher psi than normal, to flow enough. You might want to upgrade injectors to s63tu ones so you don't have to or you'll have to use meth/port injection. It's up to you, but I went this direction. Stock 97605 or whatever it is plugs at .022 ARP head studs are a good thing, but I'm not too sure when the stock head bolts will lift and cause issues. Might as well upgrade as you'll most likely go to 30psi if possible and don't want to cuss yourself for skipping them only to open the block again. How to accept the block for evo ARP head studs. 330-340whp at 21psi with Navardi. We stopped there as my fuel injectors showed clogging/dirty on logs, and with the s63tu injectors install, it has been working and tuning little by little to get power back. Last week found out the stock hpfp cannot handle these injectors over 18psi, thus the b58tu HPFP install is happening asap to continue. Previous person was able to run 27psi on this turbo with port injection (meth), so let's see what happens there with e85 down the road.

I would have gone with 3.5", you got some backpressure and could probably get a 30-40hp more with 3.5" exhaust |

Some progress!
Rotating assembly in new head, oil pump, counterbalance shaft, timing chain/guides etc. Excitement is mounting! |

I have also tested numerous intakes and stock intake box with a drop in filter works best thus far for b48 applications. |

If you really wanted to test that theory, it would be the standard downpipe into a 4" -> 3.5" burns reverse megaphone into a custom 3.5" exhaust all the way back. CTS turbo in my option does this the best for the price, but they go from 4 -> 3.5 -> 3 -> 2.8 or whatever it is (not 2.75" but not 3" either it seems). A thread way back in the past talked about this and to get rid of the bottle neck was to cut off a part of the downpipe and weld a 3" v band to ensure you were 3" all the way through. This is something I'll do as I want to replace my stock midpipe section to angle the exhaust just right. https://f30.bimmerpost.com/forums///....php?t=1589618

My 320D xdrive is fully loaded and finding a 320i with same specs and milage will cost me 10K USD more for that price I might as well get a F10 535i. I've done this on a Saab, and the results were great gained around 40hp with bigger exhaust, same boost and higher igniton! For example this guy did 370whp on a stock TD04-15T, while people before only did 300-320hp on the crank with a similar setup. This due to back pressure |
