E36 Hater's Phase 3, AKA what's a budget build?

[doktor b]

All that meat and no wheelies. :/

[E36 HateR]

No wheelies yet bro! Lol




Havebt been able to pinpoint the issue, but I have noticed on 14 and 15psi it will do it also.

Its just not as noticeable. Maybe a bad crank or cam position sensor?

Im pretty lost where to look guys.


Sometimes it pulls hard at low boost and sometimes it feels slow and that is when its missing.

Id be looking at grounds. Coil grounds, engine grounds, ect

I may replace the resistor on the coil/injector ground.

[dburt86]

Yea that mystery resistor. ive heard thats for missfire detection. I can tell you that it makes no difference at with MS. Not sure how the stock DME uses it though.

I assume youve changed coil packs and checked plugs and gaps?

Is it way rich?

[E36 HateR]

Afr is on point when it sputters, i wanna make sure my harnes is on point before i go ms plug and play.

Yes changed all new coils and plugs gapped. 015

[NOTORIOUS VR]

Boots swapped too or just coils?

[E36 HateR]

Brand new boots and coils

[E36 HateR]

The ground is broken on the harness, right where the resistor is, gonna fix it then go for a drive.

wheelie.

Car runs better and on wastegate pressure (16-17psi it doesnt misfire but on highboost it backfires LOUDLY)

Im pretty stumped and annoyed.

[jakeE36325]

Fouled plug caused by the bad coil ground? Have you checked the plugs since fixing that?

[NY98M3]

I thought the OBDI valve covers susceptible to having grounding issues? I ended up grounding every coil.

Thats pretty hopeful on an IRS car

Ill try swapping the plugs out, dont have straps to ground each coil, ill work on it this week, i just want to run the nitrous supercharged c6z's in my area lol.

It is.
but I feel like I'm helping provide motivation for Frank to really go the extra mile.

also, they don't have to be from a dig. I'm totally on board with rolling into one.

[someguy2800]

Just like this, your turn Frank!

Found the limit of the hx40 and m52 block, somewhere around 35psi and 850+whp

Stock pistons look fine, cracked the block, plugs looked perfect, popped 3 freeze plugs.

Im kind of annoyed, i took my time and did everything right, putting an sxe369 or 7175 dbb on the car and doing a low compression build on the 2.8, 8:1 so we can hit it with a 150-200 shot.

Keeping the smallest bore we can and dropping on some cams to keep the powerband happy.

At least ill be one of the first with the megasquirt pnp, ill be able to control the nitrous with it which is nice.

[rajicase]

Holy shit.

[milKt]

You popped another engine?

built?

[Bke36Is]

Sorry to read this that really sucks! Did you get the misfiring issue figured out at least?
