This is the start of my build thread. So lil back story. Bought this car a year and a half ago to be a fun daily that can get through the winter easily. Kept the car stock, changed my oil regularly with 5w-40, got vvt/timing chain done. Was going to do minor upgrades, nothing to major since this was my daily. Then the incident happened. Like most build stories it all starts with motor blowing up. So originally was going to have my warranty company repair it but they are shit and the claim got denied. So i did what any self respecting car guy would do. Got another daily and this will be a project car. My goals at the end of the day is to get between 400-500whp (or least to make sure the block can handle that much) This will be my first build and im more of a rotary guy. (currently have an rx8 that also need a rebuild but thats another story) Since my engine is shot anyway might as well build it up properly while it is apart. Im currently assembling a part list and could use any advice. Like do i have to bore out to 88mm or can i jsut get forged 87.5mm pistons to hold up to 500 whp. Which connecting rods are best., etc Most likely my block and head are shot. Would have to get the opinoin of a good machine shop. Using this also as reference:https://mazdaspeeds.org/index.php?threads/rebuild-parts-list.2519/ Parts list so far New Short block or old block bored to 88mm replaced/head 4032 forged pistons arp studs bsd kit edge stage 3 rebuild kit. I'm in no hurry to finish this and the car can sit for a while. I appreciate any and all advice. Im from south new jersey. So if anyone has a good machince shop/ good shop that can get advice from in the area, Would be appreciated Bonus pic (The carnage of cylindar 2, pistons 1/2/3 all shot)
Ok so been a while since last update and rebuilding the speed 6 got put to the back burner for while cuz of irl stuff. New build will be a built 2.5L bottom end swap instead of just a general swap still looking for about 450whp on 93 as a first goal with options of going to 600+ down the line. Parts list for the block atm 2.5L Ford Fusions Block 2.3 Mazdaspeed head Maxspeed 2.5L Connecting rods Wiseco 89mm Forged Pistons Kings Tri Metal bearings Oem Main Bolts Arp Head Studs Stock 2.5 Crankshaft Im looking at also doing a upgraded cams piper bp285 with springs but as this is my first build not sure completely what i need and am doing as much research as i can but still a bit lost. Shall take pics later once im at the garage.
