D.P.N.S the other mk3

[d.p.n.s]

another picture less update sorry..

we had another play with things on Saturday.. wasn't getting anywhere again... we stopped went through it all again and again.... and then Simon said ...what about the plugs ?

I told him they were new last weekend..so we thought fuck it ... I grabbed a set of old shitty plugs (pretty sure they came out of the motor in the old rusty wagon).... we slapped them in and she fired up.... only for a few seconds but she fired up...

I can't tell you the feelings I had when she started..... just gave me instant hope that I had done things right ....was like a massive weight of my shoulders....

still heaps to do but I know now it will work..

massive thanks to @Stufor the basic tune to make it run.... 

 

cheers.

[d.p.n.s]

had a wee play today..

moved the trigger 2 wheel around a bit so it's not to close to the crank trigger missing tooth.

put some new plugs in gapped to 25tho.  change a setting on the injector fuel main from sequential to batch fired...(after reading up a bit more the 36-1 on trigger 2 is a bad fay of doing it.. it just needs to be 1 tooth and that will help it sync better) ..so ill pull the pulley off and cut all the teeth off apart from one and put it all back together and try and get sequential injection to work.....

 

but hay in the mean time this happened 

 

[d.p.n.s]

pulled the crank and cam triggers  off..
from what I've read and other have confirmed the 36-1 trigger is really hard to sync with a 36-1 crank trigger...
so the car runs and even if I unplug the cam sensor it still runs as the injectors are being group fired.. but I want sequential so the answer is to have just 1 tooth on the cam trigger ....
so I'm just going to cut another 34 teeth of yhe wheel and go with that..

once I have the rigger sorted and the intercooler piping (ordered today) in place then I'll be able to start tuning it properly...

but she runs.... huge weight of my shoulders.

 

[d.p.n.s]

well I cut all the bar 1 tooth of the cam sensor..changed trigger 2 sync mode to CAM PULSE WINDOW  and then just set that to 50°
and she's now running both DRIECT SPARK and SEQUENTIAL INJECTION.

she basically a modern engine now with classic pinto oil leeks.. haha

not much else I can do till I make intercooler piping  (and our postal service dictates when I get the stuff)...

but even at idle the air coming out of the turbo is pretty significant.

also set the water pump temp to 70° ..
engine temp got up to 68° water pump kicked in...temp got to 71° fan kicked in and bought temp down to 65° in no time....
so I'm happy with the coolant system. RX2 70mm thick radiator,  14" fan in shroud ,electric waterpimp...

on a side note ... heater was awesome within minutes.

cheers

had bits turn up for the intercooler piping.. just had to male a flange and weld the piping where I needed it from the turbo outlet.

so apart from the speedo cable and hose for overflow tank that's everything that needs to go in the engine bay......its bloody busy in there now.

was doing a wee bit of tuning today and getting the motor upto temp ..

then when I shut it off and had lunch.. come back in the garage and found this

so it looks like the motor is coming before tuning now..

I'm not sure if it's anything major or just some leaks... the motor is an unknown and didn't cost me much $$$$$ it was only to get it all set up and tuned ..

put I'll pull it and see what's what and go from there.

[d.p.n.s]

took a couple of hours ...but the motor  ame out.. not all that hard and mostly complete.

there are a few things...leaking.
*both sump and rocker gaskets are weeping ..(rear of the sump seems pretty bad)( left rear of the rocker cover is pretty bad.)...may be another reason for the sump gasket ....get to that later.
I did put a full gasket set through it in October 2020 but it's sat dry till about a month ago.
*the clamp on the oil return had had slipped down and so had the hose and kinked it a bit (not sure if it's enough to stop oil flowing..maybe another reason for that ...) also might need a restrictor in the oil feed line
*oil on the block from the crank breather (may be another issue causing that )
..
* the main thing is I lost about a litre + on the floor..the oil cool and lines were full... and I only put 4l in.... and drained 5 out...that smelt a lot like fuel... so I think the 1st few days of fucking around with ecu setup ..it pumped so much fuel into it that it filled the sump... enough for the gasket to leak....the turbo drain to be blocked ..

so replace a few gaskets and try again...

there are a few things I wanted to do anyway and would have been easier the motor out... so 2 birds 1 stone.

 

[d.p.n.s]

pulled the sump off ...found
*gasket was fucked ..
*sump was full of crap (petrol must have cleaned the motor as I cleaned the sump last time I had it apart).
*motor is clean...oil pick up is clean .
*sump.must have been full as there was what looks like airated oil up the front of the sump (not bowl) from where it was churned up by the crank...  4x800cc injectors  may have filled the bores on a few occasions.
*pulled a main cap (didn't get a pic ) pulled a couple of big end caps and they seem ok.

also found oil in the bellhousing  and you can see a stain on the steering shaft and oil on that side ... so I'm going to say 90% of it came from seal letting go at the rear and oil coming out the turbo drain.

so on conclusion.....slap a new sump gasket in ,, a new rocker cover gasket and go again...  lol

got a few other things to do while it's out ..

 

[d.p.n.s]

few .ore bits done..
*battary box mounted ,factory jack and a wheel brace and boot cleaned.
*passenger door on , door card cleaned and also put on door (need to find a set of oldschool-ish speaker covers to cover the holes).

*sump back on motor with new gasket..
*new oil Drain from turbo done.
*tightened all the bolts around the turbo I struggling get up with motor in the car.
*made the block breather fit better and now it sealed
*put a bracket on for the dipstick tube.

*pulled the coolant temp sensor out of the ba k of the head and put a new frost plug in...   it was a good idea but a pain in the arse ti get to and when I pulled it out you could see it was starting to weep any way....
Could find anywhere to put the temp sensore other than where tha bung is at the rear of the exhaust side of the block..(will need a small heat shel).. I no its not ideal to have ut in the ocean and head is best ... but it's not really doing much ..the electric water pump has its own temp sensor in the top rad hose and that controls pump and fan (takes care of all the cooling ).

 

[d.p.n.s]

git a few bits done while engine was out... new rocker cover gasket .. some P clips to hold oil feed for turbo out the way

small heat sheld to help keep the heat away from the coolant temp sensor I moved to the black.

made a small sheld to keep heater hoses out the way and tucked back on the firewall

has a small vibration in the steering system.. turnout being the Bush that sit in the fire wall and the column slides through  it..  ended up being a ass of a job.

got the motor all back in.. nice to know she comes out and in ....with little hassle 

extended the temp sensor wires 

moved the mountings on the heat sheld... gave me a wee bit more room around the manifold 

hoses tucked out the way

back on the wheels.. now.

I also removed the oilcooler setup as the oil light would flicker so I wonder if it was low on pressure because of the cooler..

I'll grab some new oil and filter this week and then hopefully get back to tuning on Saturday....if the motor holds up.

.I dug the drivers door out and ut seems in bloody good condition.. just missing chrome surrounds (think I have a set ).

and missing door handle ..found the one from the rusty old wagon but uts broke.. (might have ti steel it from the white mk3 for now)

on a side note ... about 5 months ago I ordered some LS1 coil boots and terminals.... but actually gave up on them ever getting here.. and just made them out of the  ones I had ..

but they arrived today.. so may about better terminals. 

 

[d.p.n.s]

well that might be the end of that ... for a weee while .
put new filter and oil in today... topped up the coolant..... fired her up and she is KNOCKING  her poor brains out.....

I can continue putting things together ...
and maybe see what the other motors are like under the bench..... but I don't really have the funds to build a motor at this point....

[d.p.n.s]

hi everybody. 

just to let you know where I'm at...

I've looked at the motors I have here..

and I have a plan so cunning...you could put a tail on it and call it a weasel .

just waiting on part

[d.p.n.s]

so things have slowed down a bit now.

was trying to get it all drivable for end of October but I was also hoping the motor I was using to set it all up ......would last ..

so wasn't factoring in a motor build . I could have found another running motor but I would have had swap the head over anyway (this one is matched to adapter plate for inlet).. and it would probably need a gasket set ... so I may as well build one....... and then I thought if I'm building one I may aswell build the one I want..

I wanted one with standard bore to start with.. and out of the other 3 motors I have I have 1x 2.1 bottom end 1x .50 over bottom end and 1 that will need crank ground as run bearing had fucked it ....

so the last motor was the one in the car ......out it came

pulled it apart and pulled the head off...so far so good .. original size SOHC pistons . (what a great sight).

so at the moment I'm just doing a whole bunch of waiting ...for funds and parts.

but in the mean time I have stripped and cleaned the block and it looks good (gave it a paint ) but all in all damage was only to big end bearings.

gave the block a quick hone and it looks good ..will give it a better one once the postions arrive and I can put a rod and piston together and see if I need the block decked.

I'm also going to have a go at porting a head myself ... I have a few heads and it turns out the best casting and condition is the head off that motor .. so I stripped it and bolted it to a mates stand (just waiting on some carbide burrs and I'll get into it).

so the plan is standard bore and stroke bottom end ,forged rods,YB cosworth pistions ,under pistion oil squiters (still researching that).higher pressure oil pump, cosworth 1.3mm head gasket , ported polished head ,bigger valves, and I'll have a talk to mate PK at kennelly cams to see if he can work some magic for me...

so just waiting on parts , money and researching 

[d.p.n.s]

bits and pieces have arrived for the motor (still bits to come) but most importantly the pistons have ..so I can putva rod and pistion together and check the compression ratio to see if I need to deck the block..

turns out it's 8.263 -1 .. I'm pretty happy happy with that to run boost..

also huge thanks to nismo-Capri for rods... and info on porting heads... that will be next on the list . while I wait for some bit to turn up.

 

[d.p.n.s]

I made a start on the head today ( bit of work ).

the exhaust ports are going to be opened up being a turbo so I started with that side .. might just do a bit in the evenings after work..

this is a standard pinto exhaust port.

the manifold is allready matched to the gasket so I just put the gasket on the head and painted it to give me some guide lines.

and here's what I've done so far ... I'm paranoid about going through in one side where it is thin so I didn't do that much that side ... just opened it all up.. still only roughed at this point.
