Well im saleing my nitrous and going turbo.

I have a stage 4 CM clutch, and a F/iC

so I think I am going to go with the Dezod "make your own" signature kit

with a garrett gt3071r. I was wondering which seems to be better in the tC the .48 or the .63 A/R?

also will the 550cc injectors be enough for 8.7psi or do I need to upgrade to the 700's

 

what hp is your goal? i dont think .48 a/r is available for gt3071r, .63 is the minimum on that turbo.. 550cc is more than enough even for 10psi.. but .48 is a good setup for 250-300hp.. .63 still spools fast for the gt30 but will get you over 400hp

 

dezod has it listed in a .48

id like to hit 300-350

I was worried about spool time, but if the .63 spools pretty fast ill probably end up going with that

 

.48 is for their standard turbo.. gt30 is different from their dezod spec turbo, unless they made modifications which i doubt.. but 300-350 go for .63 a/r, you will never be worried of coming short although .48 can get to that hp but prolly on higher boost maybe at least 16psi

 

ok .63 it is then, now is 8.7 going to get me there or can i go up to the 10.15 spring on a stock internal engine and be ok

 

8.7 spring fine with boost controller.. around 14 psi will be you target boost.. 10psi spring is fine you cant just boost lower

 

ok cool, turbos are kind of new to me I get most of it, but the wastegate thing is a little confusing

so with the 8.7 spring I can boost more but I cant go below 8.7?

also whats a good boost controller, and is 14psi to much for a stock engine with 45k miles?

 

yeah you cant have a peak boost of lower than 8psi on an 8psi spring.. anything over 10psi of boost is kinda aggressive on a stock motor, you need a good tune with that.. but 350hp goal is an is aggressive, its close to the threshold where your stock internals break.. tune has to be dead on.. with 45k miles on the car i suggest being conservative

 

ok ill tune it at 9 and build a block on the side

thanks for your help man

 

350whp on stock motor and stock internals....you don't want your motor to last very long.

10psi...max of 11psi on a stock motor will last probably the life of the car on a good conservative tune.

Unless you plan on building the motor, etc. I don't see the purpose of going with the 'upgraded' turbo from a cost standpoint. The .48 a/r spools up rather quickly and holds boost very well.

With a 8.7psi spring which I believe comes with the kit you can use a MBC to adjust the boost level to 10psi or you can get the 10psi spring and use the MBC to regulate the 10psi so it doesn't overboost and you have consistent 10psi so it doesn't fluctuate between 9 and 11psi.

I traded in my nitrous kit for boost as well.

 

well eventually i plan on putting in the 2.7L stroker kit from brian crowler probably within 6months of getting the turbo system so i have big plans for the car so i figured id go ahead and get the nice turbo

 

id get a garrett 60-1 and be owning noobs on the reg.

 

make that 60-1 a 63trim .70ar

 

what do you mean by 60-1
again Im alittle new to the boost world

 

60-1 is old technology but its tried and true.

Talk to BlackKnight he is getting the stroker kit put on a shop i've been to a lot in the past few weeks.

 

ok cool

is he on here

 

Yeah i'll find a link to his thread
