GT1852V on 1.6?

[GTD_MK2]

Hi!
I've got a 91 1,6 ECODiesel , and want to change the turbo from k14 to k24.
The engine has the following Modifications:
Stock GTD intercooler, LDA Inj. Pump, governor mod, 10mm Plunger, 2,5" Downpipe and exhaust without Cat. , 30psi boost, Fuel turned up to get a light haze.
AAZ head gasket, 12.9 grade head bolts, head and manifolds light ported.

Now, i've got a Garret gt1852V from a Mercedes Sprinter van, 2.2 cdi and thought about putting it on my eco, because the k24 and still need more power...
I know that i need a control for the vnt turbo , but it should not be the problem to build one with the informations on this forum.
Has anyone ever put a gt1852v on a 1.6 before? Will it increase the power a lot? are there some flow maps for it? how much boost will it make? and how much power can i expect?

my main goal is not the faster spool of the vnts, i just want it to pull harder ^^
my k24 spools at a bit over 2100 rpm, what is ok for me, but i think with a proper control, the gt1852v should also spool faster/produce more low end boost as the old k24.

Thanks

No one ever used a vnt18?

I donŽt think you get more max hp with that turbo, it doesnŽt sound that big. But youŽll get much nicer torque with vnt than k24.

[GTD_MK2]

so you think its worth the work?

I have to build a vane control , a adapter flange and new oil feed and drain lines... only the hose from the air filter for the k24 is a direct fit

i thought it would be a upgrade on both, max hp and spool/ torque , because its got the compressor size of the vnt 20 52 and the turbine size of a vnt 22 as far as i know....
but, in the end , who cares , i got it for about 45 euro on ebay.de, and it is in a rellay good condition, but i don't want to decrease my max hp at all.

i bet its more like got the turbine of a smaller size turbo like a VNT17. and a gt20 compressor.

usually they dont take a VNT20 and a VNT23, hybrid them and call it a VNT 18.. i bet its just a touch bigger than the VNT 17. the bigger the number, generally the bigger the turbo. and ive never seen a VNT 18 be bigger or the same as a vnt20.

but either way, its gonna work alot better than a conventional turbo. if you hook the vanes up, its gonna work even better. my VNT is set up with the vanes just open all the time. it spools at about 15-1700 or so, would spool sooner with the vanes functioning..

just go ahead and throw it on there, and report back with results! i think its worth a shot for sure. nobody else seems to have much info for or against using that turbo, so i say dive on in, and report back with results!

I took some measurements on it today...
Its got a turbine exducer diameter of 40.5mm (1,6"), what is the size of the GT2356V, and the compressor inducer is 37mm (1,456") , whats the size of the gt1749VB.
But the Compressor has got an 52mm exducer instead of the 49mm of the GT1749VB.

The Turbine a/r is 0,61, the compressor a/r is .45

I think i will give it a try on the 1.6 when i got my vane control and the adapter flange done and managed to get some oil lines for it.
For now, i don#t know when i get the time to do it, but i have a spare engine, where i can prepare it ready for install and then just bolt it up to the engine in the car, as its my daily driver, and can't be longer than a weekend off the road.
Then we will see if it is an increase in HP and / or torque.
I liked the upgrade from the kkk14 to the kkk24 very much, and i only got the vnt18 to test if a vnt does what everybody speaks of . I think that its of a much more modern design, so it should get a better efficiency in its operation range.
Do you think its capable of 30 psi boost?

[honda_is_the_best]

its capable of 30 psi, but its not an efficient 30 psi at all...

[GTD_MK2]

So, if its not effective at 30psi, what boost pressure should i run in its effective range?

[honda_is_the_best]

probably 20 or so. maybe 25 if you feel like it. but an intercooler is gonna be pretty much mandatory on anything over 15 psi..
