cologne 2.9 V6 turbo questions

Hi! Some time later I want to build a 2.9 12V sierra turbo. But now I dont have enough money. I have a few questions
about Your 2.9 turbos like: Did you modified anything in the engine like crankshaft, pistons, cilynderhead, oil pump, camshaft or anything like this? Or this engine is
strong enough basically to this boost? Thank you for the ansvers!

Nope, no modification where done

Thank you

What air-fuel ratio you use at full boost? I mean that you inject more fuel what need to cool the pistons. How many percent this overdose?
Excuse me for my english. Thanks!

12.0-12.5 afr. No meaning to overdose

Thanks again you are really helpful

i have a stupid question which items do I need to build an 2.9Turbo engine? I know that turbo is most important and engine too but about other things I dont know very much....so BOV?, Wastegate? or what?

BOV, wg, some pipes, two rightside headers. and some more stuf..

and definately a book named maximum boost

Mikael are you using E85 as kryckan does? Or you lowered the compression and using petrol?

Standard compression and regular gasolin

Don't forget a decent engine-managment like Megasquirt or Haltech.

The stock ecu will not support boosted engines...

exactly

Yes I know.
I downloaded the megasquirt software for pc just to see the options.
I think I need some help when I get to that phase in building.
Maybe the end of the next year.

Hi guys,
i've been reading this forum /mostly watching the pics but it's very helpful too/ for longer time and i'm very impressed of job you're doing with pintos and colognes it's hard to believe that stock 2,9 V6 is so strong that you can boost ~1 bar. I've got sierra 2ltrs DOHC, but i've already bought 2,9V6 engine and it will be soon working in sierra the next step is trying to mount a turbo. but the worst for me is managing the engine. i have no idea how to istall megasquirt or something like that. the qustion to MIKAEL: does megasquirt in your V6 steer only injection or ignition too? is it hard to istall something like that? is the stock V6 strong enough to give it a boost ~1bar and drive it for a logner time? don't you have any problems with stock boosted engine? forgive me my english, thanks in advance for reply and big big respect for what you're doing guys!

My Megasquirt steers both ignition & injection. I use whats called TFI ignition. It´s a Ford standard and very easy to use with Megasquirt. The Megasquirt needs modificatin for that but you can order the Megasquirt with it.

It´s really easy to install to, you just cut away the original connector ant replace it with the Megasquirt connector. And replace the airtemp/watertemp sensors with bosch

Watertemp:
Bosch number: 0 280 130 026

Airtemp:
Bosch number: 0 280 130 039

And some pin translation

Original connector -> MS connector

Pin 22 (Blue/Red) -> MS37 (earth fuelpump relay)
Pin 59 (Brown) -> MS34-MS35 (Injectors)
Pin 58 (Brown) -> MS32-MS33 (Injectors)
Pin 25 (Brown/yellow) -> MS20 (Airtemp)
Pin 47 (Brown/Green) -> MS22 (TPS signal)
Pin 26 (Brown/black) -> MS26 (TPS Vref)
Pin 7 (Brown/Green) -> MS21 (Watertemp)
Pin 36 (Blue/red) -> MS36 (SPOUT)
Pin 56 (Blue/yellow) -> MS24 (PIP)
Pin 21 (Brown/yellow) -> MS30 (idle soloniod)
Pin 37 (black) -> MS28 (+12v)
Pin 57 (Black) -> MS28 (+12v)
Pin 29 (uncertain) -> MS23 (Lambda)
Pin 16 (Brown) -> earth
Pin 40 (Brown)) -> earth
Pin 46 (Brown) -> earth
Pin 60 (Brown) -> earth


I have run over 7000km with the car at 1.1 bar of boost, works to well and it´s still complety standard engine/compression

0-200 in 14 seconds


I have wrote a guide in swedish, you can copy the settings at least. It will work with 350cc injectors and a turbo thats near Garrett GT40 in size, remember to strob the ignition så it resembles the degress in Megasquirt (turn the distributor to match)

https://skogenracing.editboard.com/teknik-f1/megasquirt-traden-samlar-alla-fragor-om-detta-har-t2679.htm

ok, i've almost understood, but there is a few things. first of all...it seems that your pin translator concerns connecting MS to Pinto engine, not V6, because there is only one connection to lambda and two connections to injectors /if i get it well, injectors work in pairs - always two injectors inject gasoline in the same time/ so your translation is for engine with four injectors and one lambda...is it right?
i don't understand this:

"remember to strob the ignition så it resembles the degress in Megasquirt (turn the distributor to match)"


however, in first sight it seems to be pretty simple to mount a turbo to V6..but i'm affraid it's not so nice in reality...first of all i have to put the V6 into the place of DOHC and then i'll start real thinking about boost one of the main problems is finding proper turbine, i don't have much money, so i will have to search some used turbine...i have no idea from which stock boosted car should i search. it's really bad that i don't understand anything in swedish but i'm happy that at least you upload many photos which are very helpful,

Daniel

one other thing...what do we do with standard ECU - EEC IV..we're throwing it away?

what are "SPOUT" and "PIP"

in your "pin translator" there is no mention about ignition...you wrote it's controled by MS...but i can't see it from connections below

No it´s for V6, actually it´s the same on pinto & V6, and you only need one lambda.
Almost every injection system exept new ones injects at the same time
You must use an ignition timing light to check the timing so it matches megasquirt, simpliest is to temporary lock the timing to 10degrees and adjust the distributor with a timing light.

On a such big engine as a Ford 2.9 you will need a big turbo, check some lorry scrapheaps for large turbo. Measure the inlet impeller and output impeller. To match my setup you will need around 55mm on the inlet and 62-65 on the outlet


My english are not so good but keep asking questions and i will try to answer them. But not to many at the same time

yes, it´s useless piece of junk

Spout and PIP it for ignition controll. Actually you don´t need to understand why, just connect the cables and it will work.

OK, thank you, those information are very helpful!
if i put the V6 i'll start completing parts for turbo. it's good that you gave me dimensions of inlet and exhaust impellers, now searching will be simplier. does it make any difference if turbine is from diesel or petrol engine?

could you write me where did you buy your MS? how much does it cost?

AND OF COURSE: HAPPY NEW YEAR!!

Almost all lorrys have diesel engine so it´s a turbo from a big diesel you will need.

I bought my megasquirt here in sweden from this guy
http://www.blocket.se/vi/11141795.htm?ca=5_s
Perhaps he can sell you one (around 300 euro or something near)

But here you can order one to

Good questions Danielrad The answers helped me a lot too. Thank you Mikael for the Megasquirt help .
Does somabody have an autocad file for this part of the manifold what connects to the cylinder head?(I find this in Grey's project forum)

I have a friend who can cut this with laser machine and it will be simple if I had a cad file. Thank you for your help and a big respect for all of your pinto and V6 projects and any other
And Happy New year for you all!

Try asking grey in his project thread, not sure he is reading this thread

My friend an I don't want that much horsepower you have at the first time. around 250 HP is enough for us. What size or type of turbo do you suggest Mikael? And about megasquirt. Can I leave my air conditioner in the scorpio? I mean Megasquirt will also raise the idle when I turn on the A/C?
I want the car as comfortable like before I fit a turbo in. Thanks for your patience.

Why?

If you want lesser power just use lesser boost. I don´t recomend much smaller turbo. Perhaps a Holset HX40 or a Garrett GT30.

It should work with A/C if you have a idle soloniod
