Its a five step process, with the last step being a 150 ft-lb (35, 70, 105, 150 and 150 again).

We have followed these:
https://www.iagperformance.com/v/vspfiles/downloadables/instructions/IAG/CLOSED-DECK/IAG-Closed-Deck-Install-Guide-14-v.14.pdf

Shortblock was brand new IAG Stage 4, heads were resurfaced/machined.

I have the IAG Extreme short block with all the options, and also a built head with +1 intake/exhaust Ferrea valves and BC Stage 3...

By IAG suggestion i used the Cooper fire version with the 14mm IAG studs torqued to the spec described in the manual.

I run a GTX3582R and i feed the car E100 using 8x 1700 ID injectors.

All fine and good, except the gasket hasnt lasted one lap on the Interlagos circuit (Brazil) at 2 bar. It even started leaking at 1.7 bar.
Water did not get past 100c...oil did
not go past 110c. All logged and checked using Motec.
Then the car spit water in the windshield and started spittinf liters.

This is my second gasked attemp, first was a Cosworth gasket on the Cosworth shortblock.

I contacted IAG and they said my current shortblock would not work with the new fire lock because of distortions when it is torqued for the gaskest.

Adam is helping me with information, but i think it is a bit confusing. Could you explain better here?
Can i use the current shortblock to install this new gasket? Is it expected to be much better than cooper version? Or even double oringing?
Im trying to build a race STI, got everything else working (sequential gearbox, dry sump etc)...but cant get an engine to run a full hot lap at 600 whp! Please advice on the gasket situation!
The only way to use the new Fire-lock version is to have machining done to your block. If the block was 14mm from the start AND was shipped after 4/19/2018, then we can machine the groove for you to accept the Fire-lock ring. If this is a block that was shipped before that date, it will require honing to the next size piston. I hope that helps.

Makes more sense now, understood.
Block was 14mm from the start, but shipped november/17.
I dont want to do this honing and replacing pistons, therefore i think i will proceed to JE proseal + double oring.

Is that something that can be safely raced up to how much boost/hp?
By raced i dont mean just a hot lap, but many laps in sequence!

That is weird.
IAG considers these options as the best:

#1 IAG Fire Lock
#2 JE + double oring
#3 IAG Cooper Fire

I got that on an email from them. It was not specified which JE, though i only see one model for sale.

About the gaskets vs 2 bar, i find it very odd too, however i am not the only one.
I was fine with 2 bar on the dyno runs (some 6 runs, generating 600 whp)...but on the track, real test, hasnt lasted ONE lap...thats why im questionong racing. Many proven setups here or everywhere do not last a single lap when the car is really demanded. I need something to last dozens of laps, so i have no problem lowering to some 430whp, i just need something reliable and i am finding out 600whp at the track on the 2.5 is anything but reliable!

If you are intending on double o-rings, I strongly suggest stainless wire not copper. If you have any additional questions, shoot me an email.

Not too go off topic. Are you sure your not cramming too much ignition timing
in it? The excessive cylinder pressure spikes "could", will deff
lift heads. Im not saying that is your sole issue is that, but its something to just look into imo. Your deff not running big boost, some something else is up.

Now spitting about 3 liters of water per lap on the interlagos circuit. 2 laps, 7 liters, plus overheating from the gases going to the radiator/temp sensor.

I think 22 degrees at most! Other engines will usually see up to 26 in same conditions, so i wouldnt consider it too much!

22* where? 22* at peak load in mid rpm. Say 4krpm. Quite different then 22* at wot in the up top rpm, say 7000+rpm. So that info is sort of useless for us to be helpful.

Not to come off like a dick...

If you buy the right Adaptronic...it could run more injectors than any Subaru would ever need.

As with most brands of ecu, they sell different models with different abilities.

What do you mean "where do you put the 2nd stage at ?"

Do you mean where do you install the other injectors ? Wherever you want to install them.

Adapt and overcome...it isnt that difficult.

8 injectors? Pfft:

https://www.ebay.com/itm/Haltech-Eli...QSP2:rk:2:pf:0

Maybe check with Aluminati for multiple injector setups:
