Turbo fit L13A1 engine iDsi 250hp
hello guys
i have a buggy with the same engine as fit,
i did setup AEM fic , and tunning on stock engine seems running well, after modify the filter and header,
but that was test to my ability in tunning without dyno ( i compare to another buggy with stock setup)
Now which is the important part, and interesting also
i want the biggest turbo that will spool@ 3000 rpm and hitting the max psi,
the engine life time doesnt matter becouse this buggy isnt daily use , season to season
so whats ur recommendation for turbo ,,
i think i will go for this
TurboByGarrett.com - Catalog
i know its more expansive than the engine, but lets see whats max power from 1.3 8v honda
also the buggy is half weight of honda fitt and jazz

Well if your buggy is half the weight of the Fit anything you put on the 1.3L is going to spool slower due to less load in a given gear.
It's hard to say what your spool time will be because you will need a 28-34lb/min turbo or larger and a lot of boost.
The Garrett GT3071R you provided a link for is a 45-47lb/min turbo with a big T3 turbine side.
Now you could obviously do it, but not without using the big 1.06 A/R housing at only about 5-8psi boost (at sea level) but thats gonna be a long wait which means no torque and a crappy power curve. Plus as you note it's an expensive turbo.
Because you have an 8v, and its only 1.3L so your VEmax (if your lucky) is probably only going to be in the high 70's low 80% VE, which means you don't have a lot of exhaust energy available to push on the turbine wheel.
You might be able to use a GT2554R or a small-medium sized T28, like the GT2860RS. I normally try to steer L15A owners towards a GT28, but a "large" GT25 might be about perfect for your setup.
This should easily see you to 250HP at the crank and high boost 15-18psi at sea level. The nice part is on a good tune with some bolts on like intake, cams, exhaust you could see some astounding torque figures. There are GT2560R users on several platforms making 200whp and 225lb-ft with really wide flat torque curves. This would be a lot more fun than making the same horse power and less torque on the big laggy 3071R, just look at this map and notice that they can both move that much air just as efficiently on a smaller engine, but one requires more boost, which means more torque.
The turbine map for the GT2560R shows you it will spool pretty quickly as well. This is probably going to be anywhere between 3-4k rpm on a 80% VE 1.3L. Where the 3071R I would be surprised if you could make 5 psi on the 1.06A/R turbine before 4.5k rpm
You might be pushing it to get 250HP at the wheels as GT25s start to get inefficient and spit out really hot air at even as low as 15psi.. Race Gas, Ethanol or Methanol + Pump gas is gonna be required as charge temps will be high if you manage to squeeze that much air through a GT25. A good intercooler will go a long way to help this, at least a 3" thick core.
Another option I would consider would be a Mitsubishi TDO4 5cm2 or 6cm2 turbine housing attached to a "13G" compressor wheel. Or a Borg Warner K04 turbo from an Audi.
13G compressor map:
http://www.stealth316.com/images/td04-13g-cfm.gif
That dot at 360cfm is 29lbs/min @ 14.7psi boost at sea level. 2.0 is the pressure ratio, which at sea level is 29.4psi or 2bar absolute pressure. But since not everyone is at sea level some times just using pressure ratios is more convenient

so the GT2560R is ideal for me ,also consider the ignition system have dual spark per piston VE%%?
(here in saudi we dont have alternatives for the turbo from junk yard) so i cant choose td04 option
also will consider very big intercooler
most of the buggy driving will be in dunes which will provide more load in the engine,
