140dB said:not to forget, one of the garett bb turbos from the rb26dett will be a good choice too. they are on the large side, but is perfect for 1.3-1.5 i think......
i have tried the garett bb turbo from sr20det on a lancer 1.6 4g18. spooling by 2krpm,full 0.5bar by about 3.5krpm. this is also a good bb turbine for those on the cheap. another good one would be from the ca18det. this is also garett ball bearing.
Getting the best turbo for your needs can be a challenge.
Being a development Engineer in the past and having a diesel background you start looking for other turbo’s that are normally used for tuning cars.
Maybe this sounds stance to many but over the past 10 years we were looking to make the turbo’s as small as possible and still gaining horsepower.
The first turbo we used was a DT-4 from a 10 year old Volvo giving us power from 2000Rpm on wards and giving us 280 290Nm of torque @ 4100 RPM on a good day when the clutch is up to it and it a cold winter day. This DT-4 is a LP turbo standing for low pressure (5PSI) so getting 16PSI boost out of it the summer. Better not! Very good hear dryer.
Some years ago when I was still working on Swift Race cars they also run a racing team in the same workshop that used the 1.9 liter TDI engines from VW.
Slowly they went up to 200Hp with this original 130Hp engine and run a 24 hour race with it and ges what no problems.
I had a look at the data sheets and did some calculations and it turned out that this must be a very good turbo for a G13B engine.
On our latest turbo engines we use the GT1549 turbo having no turbo lag at all due to the fast spool up from these diesel turbo’s.
You would say this turbo does not produce top end power. Lucky for us it does that as well hitting the 170 Hp @ 10 PSI.
We like to puss it up to 17 PSI hoping to get 200 or more Hp out of the engine.
Still we have to overcome a clutch problem. @ 12 PSI the race clutch gives up.
Most manufactures say that they can handle 300Nm on the race clutch. I think most of them give way to 270Nm and not more. So we are still looking for a stronger one.
So if you want to have low end torque and still have a lots of power on the top end find your self a modern diesel turbo of a 1.9L to 2 liter engine that’s producing 100 up to 150Hp.
It’s like running a supercharger. Power when you want it.

140dB said:bro, t28 way too big for 1.3cc. unless u wan boost start at 5.5krpm. no fun.
