Hmm i always expected it to happen with the stock internals on 0.9bar and my style of driving, really wanted to get it up to 1.2 before i moved on but it didnt quite make it there lol will be interesting to see whats given up

While your here do you have a source for low comp forged pistons? Will be looking to buy in about 3-4 months if the price is what i think it is

Have you contacted JE?

JE pistons bed in fine. Just have to make sure the bores are honed properly, and the ring gaps are correct. I;ve used loads of sets in all manor of Nissan engines.

Ok we'll that's a bit better piece of mind then, there's 2 companies near me that have good reputation but like polly I'd rather have the bores dealt with and then do the rest myself. We'll see how his bedding in gets on (which should be spot on) and ill maybe copy him on every aspect of how he gapped the rings etc.

Ed what type of headgasket do you recommend? And I'm planning for up to 1.5bar so what else should I take into consideration? I say I don't want to go all out but if I'm planning too much boost then ill obviously have to....

Drop me a message if you want to know what ring gaps to use, and you should get the bores diamond honed. As for assembly, its cheaper to DIY but you wont be as good as a good engineers, expect to pay around £600 for a bottom end assembly by someone who knows what they are doing. One of mikes headgaskets will work, but only if the block AND head is machined correctly to a suitable RA finish.

IMHO as much as I admire Polly for DIY, it has caused him nothing but problems.

If you do it right, rings will settle very quickly. Do it wrong and they never will!!

Ah that's gotta suck eh stanni, good luck with the upgrade.

What is it about these cars that keeps up hooked? if only i knew.

i aint gonna match that mate i,m very contented with my 140-150hp, and i really dont yearn for any more
and be patient, the idle will probably settle down in a day or 2, my fueling was all over the shop yesterday after the engine fitment, off the scale rich on throttle lift, and off the scale lean on wot ??, and today its all back to normal

Someone still needs to beat my 14.01... Stani was getting close... Thats not been beaten for 5? years!

I don't think we will ever see another MA series engine here from anyone else get close. No harm in opening it to all Micra owners still running Micra engines...

[will930]

would that count with a heavily modded impul k13 then? im sure it would be doable lol

Recieved the conrod im going to experiment with, if theres not much in it ill have the crank machined to suit and im getting custom pistons anyway. Need to get the ex-turbo engine apart and get started! Withinthe next 2 weeks ill hopefully know if they'll work and go from there

The piston isnt being used so im going to see if the gudgeon and micra piston will press on


And heres the forged rod ill be using if all goes well

What piston and rod is that?

gd could be where it's got extra hot and burnt away? Is that where the spark plug is closest?

 

[frank]

strange eh stani ! the pistons may have more tell ?

[pork]

What gaskets you use mate? Proper nissan head gaskets or cheap ones?

 

[pollyp]

They look like pair of genuine ones

 

[Stani1029]

[pork]

Seemed to have held up good, undecided as to get decomp plate or double up like you, spose that's a cheaper option

 

[frank]

i think the gaskets hold up better on the closed blocks neil, the cast iron and alloy cylinders in the open blocks are free to expand and contract at different rates to the rest of the block, but the closed blocks have far more restraint eh

 

[pork]

Cool, mines a closed deck so game on!

armando had some custom rods made eh stani (£100 each iirc)

 

[Noddie]

I found a place that quoted £400 a set for H bream ones. I'll dig out the email if you like. That mls quote made me laugh!

 

[pollyp]

£2.25k for a HG? wtf phaha lmao

 

[Low Rider]

The MLS quote is very reasonable when you consider the tooling and setup required.

 

[Enuo]

maybe if every turbo cg owner in the country chipped in...

[frank]

the toyota rods are about 3mm longer tho aint they stani ? 2mm shorter like armando,s would be better maybe ?
edit 3mm shorter i mean, machine a bit out of the big-end, and teflon buttons stani ?

 

[Stani1029]

.

 

[frank]

should be fine then eh as long as the bigend bolts allow, you could have it opened up that .75mm eh.
and fully floating gudgeon pin with teflon buttons (to save the circlip groove machining hassle)
