Help 1310turbo issues
Turbo Mini Forums

Hello I'm new quite mechanically minded but only to a point! So bear with me.. I built a 1310 turbo about 4-5 years ago, original metro turbo engine, had all the head work and block professionally done, bored out etc, walked out with a £1800 bill without parts! they put the Pistons, cam etc in, I then bolted the head on and the box, and then she sat in the garage Until now (had a kid lol) recently started working on her again, got her on the Dyno yesterday and after setting her up 3 or 4 runs just about todo a bhp run and she does a piston ring? Smoke was coming of the breather pipes from the crank case, Could the rings have gone brittle from sitting over the years? Just got the engine out and head off tonight, on the bore you can see up and down marks, no scoring or damage, if I remember correctly they were ae Pistons and rings..

Also when removing the turbo the bottom elbow just about had a drop oil in it.. Is this right?

Another thing.. The actuator pipe that comes out the actuator into the little Union thing, then a pipe comes out the other side.. Where does this go? I thought it was just a breather pipe.. However the Dyno chap blocked it up?

Like i say I'm mechanically minded but limited on technically minded lol

Oil pressure was 60psi before rolling road
Compression was 180 on all before rolling road

Engine..
1310 ae Pistons and rings
+40 Pistons
Head is pretty much maxed out ( that's what the guy said )
Port and polished
Kent turbo updated cam
Lightened balanced fly wheel
Straight cut box
At the time was a recon turbo!
Braided oil feed to turbo

Just trying to give As much info as I can!

Thanks
Rich

boost level during the 'setup'?
ignition timing ?
compression ratio?
intercooler?

robert.

Medusa + injection = too much torque for the dyno ..https://youtu.be/qg5o0_tJxYM

All compression was at 180, now it's 180 on 1,3 and 4..

No inter cooler as yet, and unsure of boost or ignition

Too much boost and/or not enough fuel and/or too much ignition advance.

Did the rolling road guy use a wideband lambda to watch fuelling? Det cans?

Oo would that have been the turbo pipe that I though was a breather pipe? UMm unsure I know he was putting more fuel into each run and it was noticeably getting better! He was watching his screen each time during the runs etx so I presume so!
I done the timing best that I could but I don't recall hin playing with the dizzy!

Add in..

He also took the ball bearing valve thing off the top of the inlet manifold and plugged it with a bolt.. Is this correct?

whats the compression on 2 Lol

Well sadly it appears you have learned the hard way

Get it in bits and replace the piston, my guess is it will have broken the ring lands, you may even need to bore to +60 if it has marked the bore significantly.

After that I would seriously consider a better ignition system, specifically something that can retard the ignition timing on boost.

Compression on 2 is pretty much nothing lol!!

I thought that was the case.. But it's all a learning curve lol! (I'm sure I should be more annoyed than I am lol)

Well the bore is scratched or scored ( but can see up and down marks (like 2000 grit sandpaper kinda marking!?

Hmm something like mega jolt system?

Thanks Tom!

Isn't!! Scratched or scored

Also any ideas about the turbo oil return elbow being pretty much dry? I may be wrong but expected that to have oil in it!?

yup i would also say

one or omre of the following .

too high compression ratio for the boost , too much ignition advance ,too lean mixture .


what rolling road was it on ?

Medusa + injection = too much torque for the dyno ..https://youtu.be/qg5o0_tJxYM

UMm if I'm honest not a clue! I thought a rolling road was a rolling road 😂 he done all the fueling so I'd like to think that's ok! How can I lower the compression?

Piston dish and head chamber work.

Get your engine out, stripped and some pictures up.

Can someone kindly remind me how to upload photos.. Stupid I no

O here i can help with. I load my pics to photo bucket. The just click share. Copie image url and paste it here

you can do anything if you set your mind to it...
i rather blow it up winning than keep it together losing.

finish date set for project 1... march 2018

Ah found the guide lol

iphones!!

A rolling road is not just a rolling road! Unfortunately I've had to push my mini out of one.. a highly recommended one actually and he went in running. Because instead of admitting they didn't know what to do they carried on regardless. I travel 150odd miles to stick mine on the rollers now! Hopefully next time you have better luck :)

They don't die, they just get faster!

Where does that other bit of pipe go to from the union on the turbo? The other side goes to the actuator...

I was looking at mine today thinking the same thing....

Lol not a clue! But the rolling road bloke blocked it up?

Boost? how much?
