Turbo cam ?

The question has been answered, but in an obscure way. They are telling you it is not the best combo but... why?
The specific reason is your turbo...
I would be more worried about the hot side of that turbo than I would be the cam. That turbo is smaller than what I personally run on my little 3.0 liter V6! That is why you will make boost really fast, which as stated is fun, but can be dangerous to the engine at the same time. The cam has some to do with that, but nowhere near as much as that small A/R ratio coupled with a small turbine wheel. If you can, I would try to get the biggest A/R ratio turbine housing as you can for that turbo, Or, just switch turbo's all together to one that will flow more exhaust. If neither of those is an option, then just rock it and take baby steps in the tuning.
Oh, and 9.5:1 compression is great for a turbo engine.
Oh, and with that turbo, you probably will not be turning that high of RPM's coupled with boost. Therefore your current manifold will do fine as was already stated.

all in all.... either:
buy another turbo
or order a turbo cam spec'd for your setup
I personally think that both should be done, cuz w/ that turbo your gonna make a s#%tload of torque but your hp #'s arent going to be impressive,you'll also have to shift that thing way earlier than you will want/feel to .
but its cheaper to just buy a cam
you could also probly get a 1.32 exhaust housing for it which will help out your rpm range tremendously
listen to these guys on here, they know their ****!!!

turbos to small, first fi build get a cam that leaves room for error. AND DO NOT BOOST IN 5TH/6TH.. LOL swap out the rear gears. 6 speed high torque cars only need to 4 gears on the street. with boost and 4.11 gears you will be breaking **** in no time.. have fun!

This car has 4.11 gears and a little tire and a t56 it probably wont load the engine too bad and when it does it will break the tires loose. keep the boost reasonable and timing in check (don't lug the engine) and I think it will be fine. The car looks more street/ pro touring than, drag car with the boost and timing set to kill mode.

as much as the engine will hold. It's a stock short block with ARP rod bolts, ARP main studs amd ARP head studs. I did pick up another cam, Comp 227/223 .614/.610 on a 115 LSA. The motor was basically a mule to get an LS1 in the car. I'm goin with a forged 408 when this one goes. With that said, I want to have fun with for a little while and dont want to grenade it, but if it goes then it goes. I think I've pretty much talked myself into a TC76, based on the inputs here.

I am going to forged soon and gettting a bigger turbo.

Update: I've made some progress on the FI conversion project. I decided to follow the advice of you fine fellows here and changed a few things up. The short term goal is 700 fwhp. I should be driving it by the end of the month, will be running E85:
Stock shortblock LS1 (approx 9.6:1 compression)
ARP headstuds
ARP main studs
ARP rod bolts
Hand ported #317 truck heads (basic port cleanup)
Lunati dual valve spring kit
Comp Cam off the shelf "turbo" cam 227/223 .614/.610 on a 115 LSA
LS9 headgaskets
SD 80lb injectors
TC 78 with 1.05 A/R (will run 3.5" down pipe)
Precison 39mm wastegate
truck manifold hotside
3" in/out intercooler (29"x3"12" core)
dual intank Walbro 255lph pumps (second pump on a 5psi Hobbs switch)
Aeromotive boost referenced FPR
-8 AN fuel feed
-6 AN fuel return
'65 12 bolt with 3.42 gears (recent score !)
stock T56 transmission

ARP headstuds
ARP main studs

remember to run ARP main studs you should have the block line bored to square everything up.
Try to fit a 4" intercooler if you can. Treadstone units on eBay are about $350 and lots of the Supra guys use them for 1000rwhp+ builds. They are supposedly better than the $150-200 ones for sale.
