my friend and i just boosted his gsr and popped the head gasket on 10lbs after like an hour and a half. lol.
Is there anything we can do to lower the compression or keep it from blowing again? (excluding low comp pistons etc..) thanks guys.

 

I don't know about lowering compression without changing pistons or rods or crank...
I don't think you want to go that far.

You can retard the ignition timing to help save the headgasket, colder thermostat and plugs might help as well.

 

apr head studs is another option to keep the head from lifting

 

Might as well just tear the engine down and get forged pistons, rods, bearings, etc

Key: get it tuned!

 

10lbs on stock? there's your problem, drop the boost a bit till you can build it.

 

just get a Thicker Headgasket to drop it a few tenths and ARP's and you'll be fine. Plenty of people run bone stock GSR's on higher than 10psi.

Check your timing, seafoam it and tune it even if all you can afford is a VAFC and a wideband O2 sensor.
Timing so you don't have it overly aggressive and knock.
Seafoam so you get rid of carbon buildup that could create hot spots or increase compression.

 

is the car tuned? If not get it tuned or he will be replacing more than the head gasket. Use arp headstuds oem head gasket and a good tune.

 

PSI is all dependent on the Turbo used in the application.

 

op your an idiot. your not cool. you didnt tune your car. i dont know how you blow a metal head gasket. 10psi doesnt explain anything. you need to go read.

 

Whats your fuel management? Being untuned; running too much ignition will do that to head gaskets.

 

Yeah it was fully tuned for the set up. just was a b16 ecu.
well, the next day we got a new head gasket and arp head studs. we went and took off the head and it turns out it was a little more than a blown gasket. #3 cylinder was completely blown out and cracked all the way down. ill post a pic of it later today. lol. its pretty cool lookin.

 

Bye to that GSR engine.

 

pretty much yeah. lol. its totlaly ****ed. were just lookin for a block. and the next block will be sleeved with low comp pistons and forged rods. etc. haha.
dont really feel like blowing another one up yet.

 

dang...that sux for that guy.

 

X2!!

 

can anyone spot the problem? haha

 

Bah, that's an easy fix... just slap on some JB weld and call it a day.
(that was a joke)

How much mileage on the block?

 

Fully tuned as in he gave the car a full tune up (new plugs & wires, filters, fluids, etc), and is running a stock P30 ECU? Or fully tuned as in he's running a real engine management system and got it tuned by a professional on a dyno? Because that picture of the cylinder tells me that he doesn't have any engine management, and never got the car tuned (though I could be wrong).

 

hahaha. yeah, i told him to put some jb weld on it too. hahha

lol. it did have new spark plugs etc. but i mean it was a P28 ecu tuned with hondata. just for a B16. he got it with the kit. and 550cc injectors. (a lil overkill yes.. haha)

the block had about 90,000 miles on it.

 

that is not tuned lol and if you think a sleeved, pistons and rods block is going to last any longer if you try to run that map again, gl with that.

 

it wont be run on that ecu, so yeah. were trailering it to a shop to get it dyno broken in then tuned.
anyone know exactly what the dyno break in consists of? ive heard a few diff things. lol.

 

your an idiot

 

haha. well thank you. same to u too.
