Some good feedback guys...
So as a summary so far...
GT28RS rated 320hp .64 rear .rated 350hp .86 rear
GT2871R rated 440hp .86 rear or 390hp .64 rear
GT2876R rated 480hp part NO. GT2876R - 705330-2 with a .86 rear
TD05 small 16G might make 300rwhp
TD05 big 16G will make 300rwhp
TD05 18G (Rear 070) ??? will make ?rwhp
TD05 20G (Rear 080) too much lag ??
KKR430 (T3 flange) 430hp $850 + 150 for matching dump pipe
makes 276rwhp on redzones at 20 psi with standard cam...
Note: For 300rwhp, need approx 36lb per minute and 3lb of fuel per minute (12:1 AFR)
What turbo to use on a SOHC 2L to make 300rwhp ?

TD05H-20G is guaranteed to make you the power because it is more forgiving for Non-Optimal Engine setups, I'm pretty certain MRB1s' version is still 070 Exhaust Housing. Even if its 080, its the ratio between the TD05H wheel to the TD05H Exhaust Housing, so still A LOT more responsive then the TC06 080 combination. 
You should be able to make the power on a small 16G but then you would need a full proper Custom Inlet manifold and the Head ported somewhere between mild-extreme or just a Stage 3-4 Cam with sufficient clearance in the Pistons around TDC.
From the Garrett range, the price difference isn't much between the low-end models, so something in the 20G range would be the go.
Garrett 0.64 A/R with the 53mm Turbine Wheel would be comparable to the TD05H with a 8cm^2 Housing. So with that in mind >
GT2871R with the 53.1mm Inducer (475Hp) would be the pick in that range due to the Surge line being a bit better then the 460Hp version.
The GT30 Range gets onto bigger Exhaust wheels so that's out of the question. :beer

not trying to be picky but a garrett gt2871r is only rated to 350hp and would be running in choke to make 300 rwhp(excess compressor/turbine rpm) same with a 16g.
secondly on turbo engines with aftermarket cams it rare that more than .600 thou lift is used.plus to have a reliable 300 rwhp the standard head gasket should be replace with either a metal or copper item. this alone is going to space the head off the block another 20thou so valve to piston clearance isn't going to be an issue.
They simply shape the lobes to give a longer duration. The cam shaft i had made has .576 thou lift and 274 degree inlet and 558 thou lift and 271 exhaust this cam was used on John whittikas JA track car which was making around 530 hp at the flywheel.
The gt2876r is rated to 480 i would be going along these lines. As far as running a GT30R its no out of the question. DD phil is running one on his JB with a stock motor. for what i've heard he is seeing full boost by early 3000rpm and with a bigger cam and head work this should give you about a 4000 rpm power band. nice mid range torque for normal driving and but with a potent top end. the only prob is having an external gate mean more money

The GT2871R with the 53mm Inducer Comp Wheel is rated to flow 45lbs/min @ 65% efficiency...... and flows the same as a 20G @ 72% efficiency, only 3% away from Max efficiency possible.....igottasicjb wrote:not trying to be picky but a garrett gt2871r is only rated to 350hp and would be running in choke to make 300 rwhp(excess compressor/turbine rpm) same with a 16g.
GT30 Exhaust Wheel is in between the TD05H and TD06 sizes, so yeah it's not soo bad, but isn't essential.
SOHC setups require very efficient complete Exhaust systems, which probably explains why Mitsubishi went so large on the Hot-side originally.

Some 2.6s on SQC have made 3-400hp using cheap FIP ecu with the supplied map! ...little or no tweaking.
Chinese intercoolers/piping found on many fast powerful street cars.
Ball bearing turbos don't come close to eliminating the age old compromises, as many would like to believe - size 'em wrong, they stink like any plain bushing.
Even a journal bearing t28 spins up quick, enhance your tq peak & pull away strongly.
Are bb rebuildable over your way or are you screwed with replacement chra$$$$ ?
Ongoing debates on the silvia forums; Trust(mitsu) turbos vs garret gt bb.... hint.
At half the price, an evo III 16g will peel a disco potatoe. They have moved heavy 3000+ pound 2L street cars into the hi/mid 11sec zone.
After all this time, the fastest 2.6s I know of ran old inexpensive T04Bs or a 20G. They work.
mitsu turbos are available with a t3 inlet pattern. For eg. the HRC 16/20/25g series. GMC Syclone td06/17C-8cm oe turbo is a popular g54 upgrade on SQC, thats another.
With the boost cranked up in the 25-30psi range (where they seem to make exceptional torque), mitsu turbos have created monsters of various makes.
A good tune and a motor that seals up well @20+psi, the e3 16g should easily go 300+, since its already done 400 on several DSMs.
For lower boost, I'd chase 300+ with a 46trim or so t3/t4 (similar to KKR430 in size).

GT30R's are available with an internal gate .I have one :D & it comes on strong 3800 ---7000 rpm :D

The price I've got on the GT2871R with the 53mm Wheel is $1700 and that's not including the usual 5-10% discount or Postage, but make sure the Flanges on them still match the ones you already have by checking the Garrett catalog and measuring your's up.

thanks toys... horsepowerinabox.com are also doing the GT2871R for $1694 inc gst
To bolt upto my dump pipe I need the RB housing option which is $1980 inc GST (still need to change intercooler piping)
I think I'll try and save some money and go the kkr430 $850 with their dump pipe $150 ($1000)
I'll keep it simple on the SOHC.
Later I might go to a DOHC and I'll look at the bigger GT range and TD's them...

That lift must be at the valve not cam lift. Even then it's big!
Assuming those durations you have quoted are at .050" it is a HUGE cam. Camtech don't even make a cam that big. It would be equivalent to Stage 7 and have an rpm range of 5,000 to 9,000 rpm's. And good luck trying to get a decent idle..
Did you get those cam specs off toysrus?
What are you going to be using your car for? Drag racing or circuit?

It’s not a camtech cam. It was developed by Nissan motor sport Specifically for John Whitakers track car due to him no being able to make enough power on any of the available camshafts or regrinds for the 4g63t sohc. The expected power band for my engine is between 3800 ish to around 7500 rpm.
As for the specs I went through my folder of receipts for my car specifically for this post and read them straight from the print out.
The original cam had to have a spray metal treatment to built up enough material on it to machine the new lobe shape. It was suppose to cost around the $1300 but due to being screwed around for 6 months I payed less than cost...
As far as getting information off toyrus it’s not going to happen. I’m a believer in facts with supporting evidence not dreams and aspirations
the plan for my JB is to show it at first then use it for drag once i'm bored with car shows...

The reason for huge lift is for obvious Head airflow issues.......
Duration sets your RPM range.
Huge lift and low durations means extremely High ramp rates.

You need to drive a car with an EVO3 turbo. Absolutely NO COMPARISON to the stock TC06 setup, spool is insane.JD_Stazza_Brendan wrote: But i like how daves car come onto boost STRAIGHT AWAY and pulls harder then a freight train all the way to redline.
Nothing wrong with BB turbo's but MHI turbo's work well with the right bits inside
