275bhp
I have some extra money coming in soon so i'm most likely going to use it to to some engine mod's on my e90. Dynos and everything. The buget i'm working with is about 4grand. I have a list of mods in mind and the goal is 275bhp. What do you guy's think? Feel free to comment what I should add exchange or remove from the list...
Mods: AA stage 2 tune ---------------------------$500 BMS PBX (throttle mode only) --------------$200 3 Stage intake manifold --------------------$300 (used) Injen Short Ram intake + Cyba Scoops ------$60 (already have intake) Dinan throttle body ------------------------$300 Pulstar Performance Spark Plugs ------------$90 MMW catless headers ----------------------$1000 Remus Powersound Muffler -----------------$700 ---UPDATE--- So, I've taken all your advice into consideration. This is what the final mod list is looking like: AA Stage 2 off road tune 3 Stage Intake Manifold Eurobox W/ Scoops MMW Headers (gavin swears theyre gonna be done at the end of this week) BMS Patch fix ( As a double tap to make sure I don't get a CEL light ) I still can't figure out what exhaust I want, its kinda hard to pick with out hearing it in person. I'm kind of debating on doing a dyno with out it and if I'm hella close, throw a PE on the car. It keeps getting cheaper as the days go by. Should Come out to be around $2800. Cheaper than I thought... Last edited by RazRokz.!; 04-12-2012 at 11:50 AM.. |

I'd scratch a few items from your list, starting first with the BMS PBX. There shouldn't be any need to double stack the AA tune and the PBX since the AA already has really good throttle re-mapping.
I haven't tried the Injen intake, but from what I gather, that intake is not a completely sealed box. Your money would be better spent on a charcoal delete + K&N drop in. If you're looking for more options, you could buy the Euro Air Box + K&N, OEM PI, or AFE Magnum intake. Also, 86 the spark plugs and cyba scoops. I haven't seen any real evidence of HP gains from those items. |

here is my take for your 275hp machine, it would have to be perfect on all the part to get there. dynoject u need hit atleast 235hp - 240hp.
AA stage 2 tune - do it BMS PBX (throttle mode only) - do this after everything, non hp related 3 stage intake maniflod - definitly Injen Short Ram intake + Cyba Scoops - highest dyno'd gain i think is with gruppe M Dinan throttle body - dont think its available anymo Pulstar Performance Spark Plugs - dont waste your time and money MMW catless headers - do it if its ever available or ebay header but its not perfect fit. Remus Powersound Muffler - dont, its muffler only, do a full cat-back system with secondary cat removal.

Also, if you're looking to do the 3-stage intake manifold, get one from a salvage yard or search www.car-part.com. The manifold can be had for less than $300. If you get lucky, it will still have the two DISA actuators bolted on. |

Thats how much they run for used on line from your average junkyard. Forum member jntar gave me the name of a website a while back and $300 seemed like the average price for a manifold. I have it written down somewhere, but you should probably ask him to see if he still remembers.

I have access to a lift and tools on fort riley where im stationed at. I talked to gavin and he said headers soon for $1000ish so I'm hoping they get released soon. I want to do this all before I have to ship my car to Germany.

best one u can get for exhaust probably is the supersprint full setup, but thats gonna cost u over 4-5k. come with everything, header mid pipe to rear muffler. also the "detailaddicted" system looks very nice with mandrel bend pipes welded together. No official PE dyno, but it does sounds good, also Magnaflow i dont think anyone but Magnaflow dyno'd it. it sounds more mellow and deep. cat back wont give you much without changing the header though.

Skip the PBX you wont need it. Skip the intake and either do the K&N on stock or something sealed. (BMW performance or the new AFE stage 2 intake) I can't comment on the Dinan throttle body. You wont gain any power from spark plugs. If your car isnt high mileage, dont mess with them. Catless headers should be good for 15-20hp Muffler wont gain much if any power. 2-5hp at best. Pick which ever makes the sound you like. |

I wish somebody would buy the cheap ebay headers and see how much a shop would charge them to modify to fit. I'd really like to try going this route if MMW's are going to be a $1000, I can't justify that much for exhaust when I'll also need to pair it with a new muffler to get a desired sound.

i think main things would be tune, manifold, intake, headers, catless full exhaust.
