I bought 2 new turbos several years ago and now I want to put them on a 4900cc flat 12Ferrari engine , will
they do the job?

I'd need to see what these are before I could answer that question. Is the number in the topic the serial number of one of them?

I am out of town and can only give you numbers that I wrote down before I left town, I will be back on the weekend. Here are the numbers:
T3-ST4E-SB-S50-D-C 1425360650
T3-ST4E-SB-S50-D-C 55-STD0-82
S/N T-21426
MO M240620

Looks like a T04E Super 50 with a T3 F1-55 trim turbine wheel .82 A/R. They MIGHT be a little on the small side turbine wise but they should do ok.

How about recommendation for turbo size and brand

I'm confused. Are you asking if there is a different turbo we would recommend for this application? Are you looking for single or twin? How much power are you looking to make?

Correction on the poor english, not what brand but what model, Turbonetics T series, Thumper etc,
The Norwood site has a 450hp at the wheels system (a stage 1 is what they call it) for a stock motor with no internal modifications done to it. (8-10lbs of boost)

Stock the Ferrari 5 litre has 390hp at the flywheel, from your ealier comment the turbos that I have are a little on the small side, so if I need to I willl sell those and get a larger set (twin system) for the motor.

THe Bosch CIS mechanical fuel injection is getting replaced with an electronic fuel injection system with custom billet intakes fabricated for the engine (see photo)

I have twin air to air intercoolers similar in size to the Ferrari F40 and stainless plate for turbo flanges and pipe for the exhaust

Whats the total power you are looking to make with this set up?

[mouser57]

I am looking for the same, around 450 t therear wheels. Thw only difference from thr Norwood setup id not using thr origial mechanical fuel njection with a tunable EFI system to enhance metering and response. The rev limiter will be raised from 6800 to 7500 after heads redone with a new set of springs and retainers.

In a twin turbo set up for 450 at the wheels with that A/R the turbos you have should be ok. If you try to get much beyond that you might need to start looking at a larger turbine
