Motor build! up for any local suggestions!

[Murrayspeed]

Hey guys, First time posting here! So what I have is an 07 Speed3 and I was running a GT3076R with supporting mods (FMIC, 3"catless turbo back, autotec HPFP internals, accessport, meth, cpe safe seals etc etc) and basically it went kaboom cyl rod 3 broke and I now have two nice inspection holes in my block. I have a new block, crank and other stock goodies I need and am looking for some suggestions on a good motor shop somewhere closeish to Toronto. My buddy who builds Subaru's has had good luck with Gord Bush. I figured I would ask on here and see what you guys think. I am looking for 400 WHP and I am prepared to spend the money on good parts and a good motor guy. I don't want Zoom Zoom Boom again. One of the options I am looking into is a company speedperf6rmanc3 from the states who specializes in the MZR and has a CNC set up for head porting which is very temping but has a bit of a waiting list. Let me know what you think! Any help or suggestions is appreciated!!

definitley go with Gord Bush if u can. my dad has had 2 bike engines done from him, and run great and strong to this day. the next time i get an engine built, will be by him.

not trying to put down any shops in particular.....but i would stay away from CA (Competition Automotive) in richmond hill. They have built many disi's, some have been fine. quite a few have popped within 100kms. Just something to be weary about.

Next time, I'm gonna leave my car with my boy Xzibit then come back in 2 weeks...

Why not do it yourself? its not that hard as long as you get torque spec etc

there are no local shops with any success with our motors. the one with the most experience has been hit or miss, mostly miss.

stock block can take 400 whp, who was tuning you that caused the snapped rod?

my suggestion, after going over all the possibilities, and rebuilding my motor by myself

stock bearing clearances, no machine work, h-beam rods, forged pistons (stock bore), and open the ring gap up just past the oem max spec. Although you blew a rod, most problems are caused by small ring gap cracking ring lands

as well, dont run meth.

Don't run meth? You're crazy the best thing you can do to a boosted motor is run meth...

do you have a speed 3? Is your motor direct injected? Have you cracked a ring land? Have you been on mazdaspeedforums?

[tanspeed3]

ive been fine without meth, tuned to 300 whp for 2 years. one does not "need" meth. and people arent "crazy" if they dont run it.

No I don't have a speed 3

Yes all the motor I have run meth on are direct injected
No I have not crack a ring because I run meth
Yes I have been on the mazda speed forums

I fail to see proof that running a system that allows the motor to burn colder and you to achieve the same power more reliability is a bad thing.

That's awesome 300 whp is great but we are talking about 100 more horsepower than you have. In a 2.3l 4 banger 100 is big jump.

[tanspeed3]

its not so much that meth doesnt help to keep things cool. but more so when an agressive tune is added to make more power than without meth. there arent many direct injected, boosted cars out there, and you say "all" so im guessing that is more than 1. there are 2 that i know of. 3 now, but this is the past we are talking. speed3 and cobalt ss/tc. are you thinking port injected? If you are thinking diesel, thats a whole other story

I should have been more clear by stating that I do not own these but have installed and or played a part in installing and tuning with meth

Audi r8
Mazda speed 6
Isf
Is250 and 350

Not all factory boosted cars but once you slap a big turbo on there and go try to build something that will stay alive meth was added.

[tanspeed3]

kinda jelly that you got to work on an r8 lol. but yah, all engines respond differently when adding meth. some love it, some disi's blow ring lands lol

you gonna be on the dyno this saturday to confirm this 300whp?

@tanspeed3

[tanspeed3]

ill be there. hoping i dont slip the clutch on the dyno. shooting for 300whp. but we shall see. not gonna talk to much shiz, as i dont know what the dyno will net. VD plots have had me consistently in the 310wheel range. we shall see.

i did more research into this as i never really bothered to understand the differences to adding meth into a DI motor. From that i understand that meth does not like high pressure so that being said you are right meth is not as good on DI. Now i called my friend and asked why he choose to add meth to his R8 and his reason was pretty simple.

our fuel in NB is terrible almost the worst in the country so meth served as a bandage for terrible fuel although he runs 100% none mixed.

A high percentage of speed motors with cracked ringlands, including my own, were running meth.

You now have two solvents being introduced into the combustion chamber. Speeds already have a problem with fuel dilution/shearing due to the direct injection
two solvents, dissolving the oil film on the cylinder walls, tiny ring gaps, increased friction, friction produces heat which expands the rings, the ring ends butt up against each other, displacing each other up and down, cracking the ring land


building the motor, you can open up the ring gap, you can run better oil, meth is ok, heh

[Fobio]

Just to clarify...you also have meth strategy when running meth...for example, when and where does it come on? Also, as I've alluded to in the low compression thread...if you get tuned for meth and then forget to top it up, then sure, you'll introduce a cause for overheating. So to clarify, meth itself doesn't cause overheating...improper implementation, lack of strategy and care COMBINED with meth is a dangerous combo.

[Fobio]

To specify, and I may start a thread strictly for this...a deeper nuance is that a lot of ppl adopt the strategy that they'll use meth for cleaning + plus knock prevention. Therefore, they think that if the meth comes on at 5psi, then it'll be cleaning all the time. Well...not really...and Alex alludes to this...if your meth is running all the time, and cleaning the oil film from the combustion chamber, then you're doing it wrong.

Typically, I advise clients to set it to come on around 15psi of boost.
