i have a holset turbo my buddy has givin to me (brand new) model number FJR802289 (numbers on tag) and i can not find anything about it anywhere ....thought i would just ask and see if anybody knew off hand anything about it (more markings on housing a follows:H2,3H2A, 24-01-129,18.5CM,3519410(BELOW THAT IS A 5)

 

H2 is probably the turbo series. H2A/B/C/D have different options - vband, clamp plate, etc. 18.5 cm seems to be the turbine housing side. The other numbers probably have to do with casting batches so not important. Google seems to think Holsets are used on diesels a lot.

 

They are used on Cummins diesels from the factory. Cummins makes Holset. Since diesels are used in all sorts of applications (industrial machinery, farm equipment, passenger trucks, 18 wheelers, etc), there's a huge variety of Holsets.

if this turbo in question has an 18.5 cm^2 turbine housing it may be an H1E/HX40 class turbo.

A number of Rx-7's run various Holset turbos.

 

this is why i love this forum...answers every time lol....well lets hope this is a start to a great turbo set-up, next step is lookin for a good manifold and then everything else should come together around spring time

 

^^ you have determined the specs on this turbo right? you may want to consider doing that before you get premature... a poorly sized turbo can ruin an otherwise excellent kit

 

Ok..........this is a smaller turbo than a hx40....atleast the inlet side is a bit smaller than on pics i have saw ......crazy i have ben lookin for a week now and still cant find exact specs on it

 

H1C is what this holset turbo is!!!!!!!!!!!! took me weeks to find this out!!! does anybody know anything about it?


EDIT it also is comparable to the hx35

 

I just did a little poking around. Those supposedly come in a few different variations. Perhaps if you could post some pics with a measuring tape held up to the different wheels some of our Turbo gurus could offer better insight.

There are posts of pistons engines making just over 400hp on them but with very peaky power. Usually turbo numbers dont translate well between Piston engines and our rotories though. My turbo for instance is supposedly good for over 500HP on a piston engine.... but can only make a hair over 400 in a 13b with a good setup.

 

pix comin in a min....
