Gt14
Turbo Mini Forums

Axel found a turbo in a skip yesterday (along with 3 Mini Special/Exaction wheels, but that's another story :) )



Looked it up and found that it is a GT14 of a Fiat 1.9 JTD. Looks ideal for Axel's 998 that I built for low boost 100hp.

Odd thing is that all these years turboing 998s and never heard of a GT14. Anyone else heard of it?

Ups. What is the bolt patern ?

Flanges are odd. Turbine inlet that you can see is not T2/GT20 but similar. Turbine outlet looks like a GT1544 but need to check if they're the same.

Just to calrify, it came with the spare core and broken shaft but appears to have been rebuilt on a spare core as there's no play on the shaft and wheels look OK.

Nice skip find! I’m surprised that you can get conventional flange small Turbo units, many I’ve seen these days have the turbine housing as part of the exh manifold.

This could be very interresting. Some of the 1,9 jtd turbos are listed as gt1544 aswell.
I can´t find the turbine inlet bolt pattern though.

I think that this is effectively an early version of the GT1544. Similar compressor but with a higher A/R on the turbine side 0.40 instead of 0.34. Turbine outlet looks very much like the GT1544.

I've always avoided the GT1544 because of the restrictive turbine but this looks ideal for a modest 998 turbo like Axel's.

IIRC all the 1.9 jtd turbochargers from the pre-common rail 8v wastegated tiny things to the largest gt17v on the later common rail 8v engines are the same turbine inlet bolt pattern, was the 16v engine that had the manifolds and turbine housings cast as one piece.

EDIT some earlyier 16v engines may have came with split housing/manifold too. but i have never seen an 8v witha one piece manifold/turbo.

Obviously too small for a 1275 but still of interest.

I have a gtb1449 on my focus derv, turbo will give a max of 200bhp, would work well on a small bore I think.

Update, measured the turbine. Smaller diameter than the GT1544, so that would explain the higher A/R. Trim is 67 ish.

Not so sure that it is that much better than the GT1544 now but will still use it.... probably.
