Its Time To Convert To 16V Management - Parts Needed

[m_john_m 4]

Hi all,

 

i posted a while a go about finally gettting my 205 MI16 running on 16v management. I bought the car last year which was running on 8v.

 

I contacted spoox to see what parts would be required and the list is as so:

 

Mi16 engine harness

Mi16ecu

Mi16 air flow meter

Mi16 injectors

Link loom between the car & the engine harness

Potentially a flywheel and crank sensor

Cam adaptor

Rotor arm

Dizzy Cap

Ignition leads

Coilpack

 

Does anyone have any of these parts that i can buy?

 

ill stick an ad in the wanted section just in case.

 

I am looking to get the car ready for march. She will e my track slag! Didn't get to use her last year as some idiot decided to rear end me at 70mph on the motorway!

 

All advise welcome.

Why mi16 injectors my mi16 cabbie runs 16v management and uses 1.9 yellow injectors with no probs

[Anthony 1,003]

1.9 Mi16 and GTi spec 1.9 8v injectors are the same thing - typically Bosch part number 0280150762

[m_john_m 4]

ahhhh thanks. so they were just trying to sell me something i didnt need?

 

Is there any upgraded injectors i can use? i think i remember being told 306GTI green injectors (off the top of my head)

[Anthony 1,003]

Not if you're running with standard management, no - all that "uprated" injectors will achieve is making it run excessively rich and drink fuel.

 

The standard injectors are fine for up to around 175-180hp on standard management, so will be fine for a typical mild cam upgrade, 4-2-1 manifold or whatever.

Just get a wasted spark set up.

Mi16 afms will be really old.

You'll save yourself money and time and make it very reliable in the long run.

[m_john_m 4]

What's a wasted spark set up?

[Simes 248 2 Cars]

it bins all the crappy Motronic junk or in your case jetronic junk. Ignition amp, afm, cap, rotor arm, tired wiring etc....

You just need.

 

3rd party ECU

Coilpack

HT leads

GTI-6 inlet (can be done with other stuff but this is what I have had previous experience of)

Loom

Engine mapping.

Possibly more expensive than I remembered but no moving parts except for throttle pot.

Gains you about 8-10bhp too.

 

Check my rebuild thread.

 

 

and then in time you can get some throttle bodies as you'll have everything else.

[m_john_m 4]

what 3rd party ECU. something like OMEX?

 

as last year didnt go to plan i just want the car running properly so i can actually get some use out of it. next year im thinking throttle bodies or maybe even a different track car!

If your thinking of going TB's at a later date you may as well get after market management now rather than using 20+yr old motronic stuff. Emerald, DTA, Omex etc. You will get improved driveability, reliability and obviously you can optimise performance. The only downside is the initial out lay in cost, but well worth it in my opinion.

[Anthony 1,003]

I can certainly see the argument for going straight to aftermarket management if you're planning a future conversion to throttle bodies.

 

However, if you're not planning that or you're on a budget, it is a massive expense for not much gain over a decent standard Motronic setup - by the time you've got it all installed and mapped you're talking £1000-1500 depending on how much of the work you can do yourself, particularly things like building the wiring loom. That's money that would be better spent elsewhere in terms of improving a track car IMO.

 

It's certainly true that some of the original Mi16 stuff is getting a bit ropey now, wiring looms, AFM's and throttle body assembles in particular, but equally there's still plenty of good ones out there and most bits can be rebuilt or reconditioned. I can't begin to state how much better Mi16's are on proper Mi16 management compared to running on a lashed up 8v Jetronic setup, not necessarily from an outright power point of view but in terms of drivability, manners and refinement.

[m_john_m 4]

i would love to get TBs for it but at the moment i cant justify the cost as im probably only going to be using it every now and again. will only be for track use.

 

what is wrong with looms? have most of them been cut up?

 

the car has already got a cage, bucket seats and is lowered. i know not the most refined track car but its a good base to work from. i have recently resprayed it yellow.... for a laugh!

 

the only downfall i could see with the 8v management was the car didnt have much power until about 4k, then it had plenty of power. i am hoping with it running on 16v this would help.

[Anthony 1,003]

Looms are just typically a bit tired and grotty in places, and like 205 looms they're prone to corrosion as well thanks to Peugeot's penny pinching not using sealed connectors.

 

Oddly, they seem to fair much worse in a 205 engine bay than a 405 one.

 

In addition, anything that's been converted for 205 use already needs checking properly as there's plenty of people (even so called "professionals") that are completely inept when it comes to wiring and as such the looms have often been converted to an extremely poor standard.

[m_john_m 4]

Ah right ok. Is it much work in converting the loom?

 

Should any mechanic be able to do it or should it be done by an auto electrician

[m_john_m 4]

is it just a standard MI16 flywheel i need like in the below link?

if not can someone point me in the right direction of one?

 

Would it be sensible to change the clutch when the flywheel is getting changed?

[Anthony 1,003]

Might be worth checking to see if you already have an Mi16 flywheel fitted.

 

Even when bodged onto 8v Jetronic, typically the original Mi16 flywheel is still used which makes converting that bit easier.

 

Easiest was is to look to see if you have the timing teeth next to the starter ring gear - Jetronic flywheels don't have them.

If you can source known good parts that have come off a working car, this is a grand idea, if however you end up with a ropey loom, or some other component showing it's age through temporary hard to spot faults, you could be chasing your tail for ages tracking down the problem. It's a risk, just source your parts carefully to minimise this. Additionally...

 

If you've got the time, and the inclination, getting a wiring diagram, going to electrical wiring products, and building yourself a new loom (probably for about a hundred quid and many hours) would minimise the main and hardest risk of option 1, intermittent loom faults, and resistance from corrosion on the loom / poor connectors.

 

if you're going to after market, you may as well save up, get a new loom built (sandy does them, and their spot on), and a good set of ITBS (jenvey or similar), that way you map it once, and the loom is built to support the sensors that the ITBS will use, not the sensors on the Mi loom. This will most likely be throttle pot, air temp, and possibly wide band lambda for closed loop running.

 

Hope this helps.

[m_john_m 4]

thanks for the advise.

 

I bought the loom off a fella on facebook. he had quite a few parts so sort of an all in one buy. he said the loom is in good condition and will convert it to suit a 205.

 

Im hoping it will be ok.....

 

i would ideally like a set of bodies but at the moment cant justify the cost, i just want to get some use out of it this year. i may get something else next year as a track slag. who knows

[kyepan 291]

you can pull the wrapping off the loom and clean / inspect it, then re wrap it using correct stuff.
