EJ22 N/A block getting boosted

[94 Leone]

Sounds just like any budget of mine

[ReubenH]

Yeah, if I squeezed any harder on this budget, I'd be popping out diamonds.

[94 Leone]

Could you not take the stronger rods and crank from a turbo ej20 and just use the 2.2 pistons? Being they are the same stroke?

[ReubenH]

Are the crank and rods any different? I didn't think they were...

[94 Leone]

Not sure to be honest, just thinking that maybe the turbo ones may have been a stronger design.

[DacerX]

V7 rods would be the go id say someome was selling a set cheap

[hijacka]

Rods and cranks get better as the years go on.. im not just talking about p1 vs p2 being centre vs rear thrust but more in p1 only with the machining side of things (the drilling of the cranks gets better as the years go on.). also the rods get slightly stronger/thicker.

ej22 block turbo'd will require aftermarket pistons anyway so why stop there?

[ReubenH]

I'm not so sure it would need aftermarket, cast turbo pistons can actually handle a fair bit, only STis run forged, and even then they are only half forged. No, compression is the only issue, and with old legacy 20G heads's I'm under 8.5:1, which is low as ****. Lower than a stock ej20g, and they are good for the ammount of power I want out of this engine (less than an STi)

I must stress again this is a cheap as chips daily driver build, nothing fancy to see here. Just EJ22 because why not, and I've always wanted to see what one would go like.

[hijacka]

ej22 cast turbo piston? Dont the factory ej22 cast piston protrude above deck and are high comp?.. if your going to use factory ej22 pistons then you risk cracking ring land not to mention the older design slaps like hell.. end of the day its your money your wasting(keeping in mind you have to get everything machined and pay for gaskets and seals, bearing and rings, oil pump is good idea.. theres at least 2g in all that alone.

[ReubenH]

Staff discounts are awesome, and I have a spare block lined up.

CHUR.

dahahahaha

[Marky]

I reckon just run it as it stands now, see how it goes

If it goes bang then worry about rebuilding it and trying to make something of it, it might go fast enough in "plus T" format as it is anyway. Since you can't exactly lean on a low comp build with stock everything else, higher comp would give a better driving car for the low power daily lols you're after

But then it's not my money or time involved I guess

[scoobygt]

The ej22e with the 9:7:1 CR has the pistons that protrude out the top of the block ever so slightly so what size thickness HG were you planning on running so the valves don't come into contact with the pistons? People run 18psi all day on the P1 blocks so your not going to have an issue strength wise, If you aimed for a final CR of 9:1 or 8:5:1 i'd say coupled with a TD05 running 1 bar or more you'd have a very fast Blighter

[ReubenH]

Yeah that's the plan. I whipped the heads off quickly after work today, and ****ing what a manky engine! I could have picked better TBH, but it's slim pickings these days. bores look alright, but I didn't measure anything, piston crowns are literally flaking with carbon build up, damn nana cars... The pistons are dished, and have valve recesses, but I forgot to see if they come up proud of the deck. Block is orangy brown in all the water galleries, I'm now seriously thinking of getting it acid dipped when the block is split, and sending all the bolts away to get cleaned up and coated too.

Tomorrow I'll see what I can achieve, I have a feeling it will be useless for me to measure the piston cc's as is, def need to do that when re-assembled.

STP oil flush, Prestone radiator flush, and boost will clean that engine right up!

[ReubenH]

Heck yeah, just lean it out with extra boost to burn out that crap.

Does that stuff really work?

[ReubenH]

Probably not, but sarcasm works a treat.

Ha. ha. I get it now.

Back to the cave I go.

[ReubenH]

Here's the promised pics of the block. Ew. Dunno why cyl2 looks mint, and all the others are messed.

Maybe it had slight hg leakage and water vapour cleaned it up haha

We demand updates, what are we paying for

[94 Leone]

That reminds me. Membership is up for renewal soon.

and I want to follow this build because I have an N/A ej22 block i have plans for. Like swap out crank and rods from a turbo engine kind of ideas.

[DacerX]

Yes renewals reminders will be out in the next week for members that are over due or getting close.

[pawan]

Been reading this thread with interest has there been any updates?
