Good size turbo?
 

Alright guys i got a garrett with these stats 3" inlet, 2" outlet, .5AR (cold side) 3" v-band and T3 divided flange .83AR (hot side).....is there gonna be too much lag on a stock ls motor? or will this be perfect? I could do the math but i like the opinions from here better

Re: Good size turbo?
 

I think its gonna be laggy, its a straight t4

Re: Good size turbo?
 

what rpm you think it would kick in

Re: Good size turbo?
 

I am no expert on this turbo, I never used one but I can guess about 5500rpm which I not bad in my opinion, cause I usually launched higher than that.

Re: Good size turbo?
 

even with the smaller cold side, i know the hot side is pretty big though....thats gonna be pretty late for it to kick in on a stock ls with a rev limit of 7200 dont ya think.....well maybe i can be ok with it, do ya think it will hit pretty hard?

Re: Good size turbo?
 

sell it and buy a smaller one, the cold side dont affect spool that much, its mainly the hot side, I am running a sc61 on a built ls/vtec and its a 63 a/r hot side, and its very laggy in normal driving condition, but it kicks in about 4300rpms and hit hard, but I havent put any raping into it yet since the motor havent broke,or tuned yet. just testing its also a brand new turbo so it needs some break in time.
so your turbo will feel like ---- untill it spools

Re: Good size turbo?
 

So you think its gonna hit full boost at 5500 or just start?

Re: Good size turbo?
 

maybe, I never used that turbo before, a turbo like that is not practical for a street car, you would hate life, and if you ever driven a car with a smaller turbo the lag will feel even worst.

Re: Good size turbo?
 

No i havent this is my first turbo project, man i thought it was a good one too, i mean i thought it was a little big, but that I would be able to work with it dang :P

Re: Good size turbo?
 

Does anyone else have any opinion about this turbos stats?

Re: Good size turbo?
 

I would have to agree with its lagginess. It wouldnt be worth it get a smaller t3t4 with like a 48ar or 63 that way youll start boost at like 2,500-3k much funner to drive.

Re: Good size turbo?
 

there so damn expensive though, everyone that I see is over 300 and im not trying to spend that much on a turbo

Re: Good size turbo?
 

you can sell that turbo you have that amount if its in good shape, check abay, I know where a saab turbo is but its gonna cost you, they will charge me $120 for it and I will charge you $200 because I have to remove it from the car, and ship it. its too small anyway 48/42

Re: Good size turbo?
 

well supposedly its a brand new turbo, and it looks perfect to me so who would be interested in something with those ars?>

Re: Good size turbo?
 

K how about the stats on this turbo? Garrett t3/t4 turbo, intake AR.50 exhaust side AR.60.....is this more like it?

Re: Good size turbo?
 

just get a smaller turbine. the compressor side is a good size.
