A few bits done this evening.

All boost hoses on.

Gear cables back on, (don't know why but for some reason I hate this part!)

Whilst I wait for my for gauge to turn up, I primed the pump and tested for leaks none...few!

So ID1050x injectors can fit on a standard loom with a 2zz.

I need to think about modifying the fuel pump cover as with the return line in now it doesn't fit back on properly.

Depending how it goes tomorrow with other jobs I might go for a start.

Awesome progress, I have a question on the cross member massaging. I did something stupid, purchased Borg Warner 6758 turbo and have equal length tubular manifold that sits rly low so I think ill have to mod the cross member. How did you do it?

Thanks, I heated mine up with some plus gas (plumbers gas) and then hit it with a big hammer a few times!

Soooooo....

Had some time this evening.

1st things first:

Checked injectors were firing. Tick.

Checked coils were firing. Tick.

It's got oil in. Tick.

It's got coolant in. Tick.

Quick once over with the 10mm, 12mm and 14mm. Done.

Crank for oil pressure. Tick.

Go for start....nothing just cranking.....

Try again.....nothing....

Have I set the new injectors up properly in the ECU? Quick check. Yes.

Scratching my head thinking which way would be best to set the thing on fire....

Look behind the drivers seat....

I'd not plugged the loom back into the fuel pump. Knob head!

Plugged it back in.

Went for a start, boom and we're away and a much smoother idle than before.


Let it run for a few minutes giving it some different loads.

Now to get the driveshafts back in and we're away again!

So my spare fuel pressure regulator gauge turned up to today, as I'd broken the other when I put the engine.

So wound the gauge in to see where we were sitting....

60psi...wow that's a little on the high side, went to turn the screw down and it wouldn't go any lower....

Some Head scratching later and after dismantling the fpr, I'd determined that the spring was too stiff above the bladder.

So I took it out and tried to manipulate it a little and it was having non of it.

So thinking back to some YouTube videos I'd been watching recently of material properties and heat treatment and what it can do to metals. +(I've also studied material properties at Uni a long time ago!)

I decides to heat up the spring until cherry red, compress it a little and let it cool slowly.

Once cooled I popped it back in and tightened everything back up, prime the pump, boom 40psi and adjustability, we're back in the game!

I would replace that regulator something isnt right, heating the spring like that may of got you by but could also weaken it and you really dont need that on such a critical item.

Good work so far though looks like wont be long until its making power :D

Yeah talking it through with guys today at work we were discussing it's viability and how it would react to boost pressure.

I've ordered another regulator to be on the safe side anyway.

Some systems run at 58psi,maybe just the wrong one purchased?
...neutiquam erro.

So I've been a busy boy the last couple of days out getting some miles on it.

1st today properly leaning into it, still don't have the big cam set up on the ECU yet.

But feck me! I saw 25 psi a few times today. Absolutely terrifying!

Dropping the oil today for a check, gapping the plugs a little closer and a general check out and all seems good.

A few actually, but if I'm to hit my goal of 400-500hp it'll need to see that and more 😁

So getting some miles on the car is/was going well.

I was having an issue with a random miss fire and whilst trying to diagnose I took the cam cover off and cams out to check the valve springs.

I then set the timing up again and went out again.

It still wasn't right but me being me still gave it no mechanical sympathy whatsoever.

End of a pull and an enormous backfire and then the car running dog rough, so I limped it home.

Back at home checked the compression, 50psi......on all cylinders.

Something isn't right here.

Left it for the weekend and considered my options.

Pull it out and full rebuild to see what wrong?

Buy another motor in the short term?

I ended up doing a bit of both.

Set of brand new coils from RRR.

New plugs.

Found out I was running half a millisecond short of dwell timing. So that should be the misfire issue.

So back home tonight, cam cover off to see if I could see anything.

Engine at TDC, cam lobes weren't lining up properly.

Looks like it's skipped a tooth or two, hence the poor compression on all cylinders.

So chain off, cams timed up again and back in with the chain tensioner.

I think the tensioner may not have released properly first time round and pottering about with light throttle may not have been noticeable.

Quick test of compression and we're back at 175psi on all cylinders.

And started sweet as a nit first turn of the key.

Phew!!

Chain and cam hears are less than 1500miles old an in good condition so I'm just going to keep an eye on it.

Still going to pick up a new engine tomorrow night as I've committed and don't want to let the guy down by messing him about.

Second engine picked up.

Quick 4 hour round trip after work.... :o

You cannot view this attachment.

Little bit of tinkering tonight, had a weep from a coolant hose on the intake side of the engine.

I was hoping it was one of the ones going into the oil cooler.

It was, but it was from the block side so had to remove the starter motor to get to it.

I'd even said to myself when putting the new hose kit on, "why are you removing hoses that aren't leaking?"

That should be that sorted now.

Just got a slight weep from one of the oil pan bolts now, but I'll sort that when I next drop the oil.

So managed to get the car running brilliantly.

However, I think it's previous overheating issue before I got it may have warped the head and I'm kicking myself for not checking it.

Car runs brilliantly, but has a slight weep of oil from the head near cylinder 1 and after taking the cam cover off the oil breather is showing signs of mayonnaise.

I'm going to bite the bullet and chuck my new engine in on a smaller frame turbo.

Small set back.

But should be hopefully be a quick turn around.

Only had a few hours this afternoon as I'd been out in the morning, but long enough to get it on two mounts.

I have the same manifold and will be fitting the turbo with the cold side pointing left. I hope my turbo is a bit smaller than your holset as it is the small frame efr.

How do you like the manifold? Arent the runners too small? I am thinking to mock the turbo with the engine in the car and if I dont like it to go custom. I hope it fits okay otherwise I will flood the private sales with parts 😁

So we are fully in, connected up etc went for the 1st start ....I've used the starter of the 2nd hand engine I got..... solenoid fires but starter doesn't spin.

I just laughed called it a stubborn tw@t and got a beer.

I'll double check all grounds this weekend and if not bung my old 1zz starter back in as that's a known working one.




Old exhaust is back on after making a new downpipe with a spare 2.5" mild steel 90 I had laying around and a spare o2 bung, which then mates back up to the old system.

I'm contemplating what money I've got in the built 2zz in parts, plus spares etc and seriously considering K24 turbo instead of building my other motor up.

Stock block good for 450hp, better aftermarket support etc.

Just weighing up my options for the moment.

Home tonight after a couple of days working away.

Starter swapped over.

Key turned, started 1st time.

This engine is sooo smooth compared to the one that has come out so will be interesting to see what's going on internally.

I'm leaning towards the head being bad as it's the only thing I didn't rebuild. Or it's the bottom end, because that's the thing I did rebuild 🤣

Anyway small oil leak from the oil cooler pipe (looks like it got kinked and damaged with all the in and out)

But other than that I at least know the issue is mechanical and not in the map or harness etc.

I might just bung the oil cooler ports up to start with rather than faffing with a new hose.

How much power do you want in an Mr2?
My V6 was putting down at least 250 whp and torque and was frankly dangerous in the wet. More power doesn't always make a car more fun.
First they came for the socialists, and I did not speak out—because I was not a socialist.
Then they came for the Jews, and I did not speak out—because I was not a Jew.
Then they came for me—and there was no one left to speak for me.

Did the car have an LSD? Throwing a 200bhp tune MR2 around a wet track at 10/10th, I've never found it too unpredictable (although harder to be fast relative to the FWD competition)

Although an interesting question where is the max range for power whilst keeping the balance and usability.

Depends what you want from the car though, I love projects where people do it because they can.

What UK mr2 doesn't?
Mine had an S51/54 box out of a Mk2 with the standard Lsd. Broke one drive shaft probably on the dyno.
I know nothing about driving on track
My favourite Mr2 was my V6 before supercharging. 200 ish NA hp more torque.
Whatever you do I hope it puts a smile on your face.
