ømëga engine options could use some second opinions

[Festiver]

So ømëga will be my daily no crazy horsepower no mind blowing cornering abilities just present beautiful and practical and economical also it will tow another festiva on a small trailer build for a festiva
Fuel efficiency
Torque
Decent power (no reason to aim to be slow as a dog)
And reliability is key

Mazda b series engines have really proved to be some of the best in my opinion and the torque of a bp is just amazing after 35mph I just leave her in fifth and can easily cruise up most hills at 1700 rpm at light throttle fuel efficiency hasn't been fantastic even though I'm a pretty decent ecodriver, usually get 22 mpg where as the ol b3 usually got 45mpg.

Anyway here's what I'm thinking as far as options again aiming for
fuel efficiency (would prefer 35+ with very light highway driving)
towing
also I live in a very hilly area "if its not uphill it's down hill"

B3+T ehh maybe towing itd probably do it but how much stress

Zjve 1.3 dohc jdm only basically 2nd gen b3 but I'd need to do a ms ecu as parts are a pain to get engine is cheap though

B6d I'd need to see in action they seem decent though

B6t great engine but I'd feel like the economy would be trash towing

B8 Charlie suggested and I'm debating it but torque compared to bp? Also economy vs the bp?

Bp major possibility just i feel fuel efficiency isn't too great with this engine

Bpt ehh idk POWAAA but that's what other cars are for festivas don't need all the power

Vw TDI? This has been bouncing around in my thoughts for some time I mean itd do everything I want well I just have to research the reliability more

Vw Awp 1.8t nope not dealing with 20 bent valves (which is inconvenient because there's a good engine in my garage now for sale)

Also I have been looking around for this info I have been trying to choose for a while Charlie suggested the b8me in the other thread and I trust his choice and am definitely debating it I just want to know others thoughts and opinions to me this is kinda like a tattoo where if its going in its staying in unless major issues

B8/BP is the best option if you want to regularly tow 2000+ pounds.

The problem I see is the current 22mpg you're getting now. That's way below the average i see on here with that swap. Better check the o2 sensor voltage and cam timing.

My o2 was showing .3v a little on the lean side and I 95% sure I got the cam timing right also the voltage was at idle I'd like to get a lc1 wideband to know what's really going on all across the rev range also my wot has less power then my 3/4

The stock ecu has some weird fueling. According to my wideband at WOT it runs leaner than at 50-75% throttle. If I'm running on the stock b3 injectors full throttle runs 17:1 afr or leaner. 50-75% throttle is around 15-16:1 and it pulls harder. If I put larger injectors in it does the same thing just way richer. Get a wideband in there narrow bands are almost useless for tuning IMO.

Exactly its like a guess and that is odd maybe run bigger injectors and dial back your vaf

I've got the vaf leaned out like 15 clicks. Need to go with smaller injectors and bump fuel pressure.

[Advancedynamix]

You should NEVER need 15 clicks on a VAF adjustment. Something is wrong there. 4 clicks is huuuge.

Also, check into the ZMDE 1.6 DOHC engines that came in early 2000s Protege. With the complete obd2 system, you'd have a car with excellent mileage, great TQ and parts availability too. The JDM version is 1.5L and the engines go cheap when they come up on eBay. Nobody wants them for anything.

I have 20 bent valves in my garage as well!

Lol that sucks mine hasnt grenaded yet but a few guys on here told me to look into the timing belt reliability and it was less than impressive

:dontknow: 220cc ish injectors with a b3 ecu. Brings my midrange down to around 13-14:1 Its around 9-10:1 at high rpms and full throttle.

[bhazard]

This mix and match injectors and vaf and ecu crap sounds like way more hassle than it's worth.

[shorestiva]

Oh it is. I have a plug n play megasquirt sitting here that would make life much easier. My plan was to get it running as good as possible on the stock ecu, dyno it, then drop in the megasquirt and see how much power I gain. I think if I was running a normal b6d it wouldn't be as bad.

I forgot about that lil guy ok so b8 bp zjve zmde and I'm still kicking TDI around idk

I'm planning on a B6d on B3 fuel injection later this month. This will be an auto b6d with Capri manifolds, so it wont be totally comparable to what Joe is running, but it should help me to give better tuning advice. Right now all I have is what I've seen with Dragonhealers car. That car fueled fine with b3 injectors at WOT.
