Need a better cam man. Those cams are junk if you are only making 325 at 16psi. With a similar setup on crower 404s Im making 370 on 15psi

Yeah but the crane and crower turbo cams idle really well, they move the powerband up about 800-1000 rpm . the smaller exhaust housing wont help with power IMO

Re: Time to Upgrade. Input needed
true but on a 2L motor that .48 turbine housing imo is probably choking the potential of the motor. the larger the turbine housing and turbine wheel you can get more hp at lower boost. for example the 6262 nad 6265. the 6265 has larger turbine wheel and can only come in a .82 housing or larger and you can obtain the same hp and lower boost leves at the staright 6262

Yeah ditch that .48 man. It's killin you. At least a .63 or even an .82 if you decide to move the powerband up a little with cams. Good news is it's an inexpensive upgrade.

Re: Time to Upgrade. Input needed
Definitely will need bigger injectors, and bigger turbo. Do u already have an aftermarket fuel pump? Surprised no ones mentioned that if not u will def need one

Re: Time to Upgrade. Input needed
I just copied and pasted from the sale add I bought the car from. I have an aftermarket pump in already. So looking like I should look into some 1000cc injectors and a larger housing maybe some cams? Where is a good place to buy a a larger housing. There are a million sites to buy parts from, I just dont know who is best to deal with.

This is the dyno of the car. It even says its a .48. So i am confused because I searched and could not find that spec? Any one know where I can get an upgrade kit for this turbo online?

Re: Time to Upgrade. Input needed
You're definitely choking with the housing, but like Shodan said there is something fishy about that turbo.
Post pics? Either way, that's your problem. And as for making 500 on an LS, all you really need a VTEC head and a bigger AR, probably a .82 for best results.

I will get some pics of it or even try to find a part number. As far as vtec heads go do they have any weak points in them or is it as simple as bolting one on and your good to go to XXX amount of power.

Re: Time to Upgrade. Input needed
700382-5012 are the numbers i could get. I think it a .60 then? I am lost at this point. Any logical and useful input is welcomed.

Re: Time to Upgrade. Input needed
I know the housing is small but i built the engine so it would be a street beast...that's evidenced by the fact that full boost is reached very early and spool is pretty much on demand.
If he wants to upgrade, a larger trim is necessary, i agree.
Also, ditching the recirculated dump wouldn't be a bad idea. I put that in to keep the car streetable and livable - read: quieter. Ditching that would free up some power.
Other than that, you're looking at a VTEC head. I wouldn't do it. I'd get the larger trimmed turbo and ditch the recirculated dump and see where that gets you. That head doesn't have many miles on it and it's completely rebuilt and upgraded. No need to throw it out.
The head is not ported, however. It was just "refreshed" since the original OEM head had 150k on it.

Re: Time to Upgrade. Input needed
Yes, that's a GT3076R. Yes that uses a .60A/R compressor cover. No, it does not use a .48A/R turbine housing. Sounds like a typo. Either way, you won't do 500whp on pump gas with it, as it is only 52lbs/min. You need to go up to about 58lbs/min or slightly higher to do it.

I believe that's it, but I am not positive. I've never looked into that and now I don't have a turbo, haha.
