id go with the studs and firering first. 4k springs and plate. then get ur clutch. cause just that stuff wont ad lots of power. when u get ur clutch then u dont have to worry bout burnin ur old one up with ur injectors and turbo.

I dont think you'd need a fire ring for 550? just studs, and why dont you go with twins?

 

[UndrGrndPrdcts]

Hmm that makes sense too.

 

[UndrGrndPrdcts]

I was going to go with fire rings because i would like to have around 700 in the future and i dont have money for twins

 

[crazyrunner33]

I'd recommend oringing the head instead. The 62/68 is a good turbo, I'd say keep that and it'll go really well with twins if you'd like more power someday.

 

[UndrGrndPrdcts]

Thats exactly what i was thinking with the turbo. How much would it cost to oring and stud?

 

[crazyrunner33]

It depends, to oring the head it'll cost anywhere between 200 and 400. You can oring your head and use the stock studs, there's a few people making over 600 hp with the stock studs and orings. The studs will be around 400 dollars.

See Im pretty sure my local shop will fire ring and stud it for 800 here but im not positive. I also heard of guys retorqueing their stock bolts on a stock gasket and had good luck with that. Think i could get away with retorqueing for awhile until i get my other turbo and stuff?

 

[Deanson]

no guarantee's but alot of guys do it and hold lots of power.....just dont run to much timing

 

[crazyrunner33]

I wouldn't recommend fire ringing unless if it were for competition only, quite a few people haven't had good luck with fire rings holding up to the high amount of heat cycles.

 

[KMKDIESEL]

I run stock head bolts and stock gasket, no oring or fire ring on my pull truck last year with a 63/17 turbo with no problems at all, but i did torque them down as tight as I could get them and ran 21.5* timing wouldnt run much over that anyways with stock pistons

 

[UndrGrndPrdcts]

Hmm alot of input guys keep it up. Think im going to oring it but still not sure when. What would it be like to run stock timing with 5x14 injectors for awhile? Until i can get it oringed, timed, and valve springs installed all at the same time.

 

[UndrGrndPrdcts]

Anyone know if that would be OK?

 

[CATSTACKS]

id say your fine with out fire ringing... unless your making SERIOUS power like kmk diesel said...
and last price i checked was at ATS in aurora colorado and the quote i got there was $1400! ((includes machining, rings, head gasket, everything you need...)) i didnt even pay that much for my engine haha... and <sed engine is a 2000 24v with my 180 pump and compound turbos... and i dont plan on saving money for fire ringing any time soon...

with my VGT my engine has seen the 50psi gauge pegged many a time... 248,ooo and no problems yet... only thing im leakin is black gold haha
