Guys,

still desperately trying to find a GT1752 I ran into a GT1749. Is this any good on a 1000-engine with 8-valve bimmer head?

Strange btw that you cannot find any specs of the GT1752 nor the GT1749 on the Garrett-site.

Here's a nice shiney one! :)

no, unfortunately not, the guy just gave me 1749 but does not seem to have the intelligence to supply me with more details.

Ik looked it up and it seems to be the turbocharger which is used in all the 1.9 VAG-diesels.

I do not have "the knowledege" (yet!) off all this turbo-stuff but on the Garrett-site it says;

can you put an 8 valve bimmer head on a thou?

i was of the impression this wasnt possible?

"Turbo's make torque, and torque makes fun"

"did you know you can toast potato waffles?"

i think that may be a vnt turbo ,thats a technical challenge to get running right and may not be what you want .do a google on vnt.

Slightly irrelevant....

But I measured up a Subaru TD04 the other day.

Minor 40.6mm
Major 56mm
and 20.9mm tall compressor wheel.

Dinky little thing. But good for 250bhp or so on a Subaru..maybe a tad more at a push.

9.85 @ 145mph
202mph standing mile
speed didn't kill me, but taxation probably will

Fastest 998 mini in the world? 13.05 1/4 mile 106mph

Its ALOT of effort to put an 8 Valve head on nd TBH if your going for big power surely you'd be better off using a 1275 block to start with?

I beleive the 8V heads have 24cc chambers as opposed to the 18cc of the 16V so CR shouldn't be a problem if your using an 8V head and a "reasonable" bore size.

My CR is 8.8:1 on +20 bore and there is a few CC's left to be taken out the head and pistons if need be

Got a serial-number from the GT1749;

9654919580

more numbers; 753556-2 HI200391F

Reason I'm going for the bimmer on a 1000 is that I allways wanted to restore my original engine but then add some grunt.

I could go for a 16v on my 1310 engine, but if it ain't broke then don't try to fix it. First upgrade the 1000, put in in the car and then we'll see if we have enough spirit to do a 16v conversion on the 1310 also.

Anybody got any clue with the serial numbers?

The identity tag also states "made in France" that gives me the shizzles.
In Holland we always say; France is a nice country, to bad French people live in it

yep thats a vnt off a peugoet or citroen , perhaps not the best choice at the moment

Just managed to get hold of a gt1752 brand new for £50 dont know if its of use but was cheap and worth the punt The numbers on the casing are 55560913 j1303027 can anybody shed any light?

if its a 1752 it shpuld be good.

its a saab one, a nice find at that price!

Dam you guys, I was going to say it was useless and offer to buy it of Star Mag for the £50 he paid.

Well it hasnt gone on the mini yet i have put it on my r5 as my t2 hybrid thing was smoking badly! It seems to be a stonking little turbo! Currently running at 18 psi it boosts from just over 2000rpm and boost hard until about 6500rpm its very similar to my old T2 that had a slighty bigger compressor wheel but with lots more grunt! cant wait to try it on the mini!

Re succumbed to the hairdryer thingie...

and been huntin' for a suitable one
so after a few odd ones volvo, diesel gt1544v..


i seemed to have found a saab 9.3 gt1752, petrol one.. but not for 50 quid.. more like 100. have to haggle a bit..looks mint btw.

how do i find out if surge is a problem at alpine alititude ?

i know Paul has estimated a map.. i guess that is my best bet then?

That sir, is not rust, it is the progressive mass reduction system

http://aseriesmodifications.wordpress.com/

bit more info on this turbo ,

the car ran 104mph terminal at avon ,14 psi across the line ,and a momentary glitch at 17 psi ,

substantial surge of power going from 12 to 17 psi ,even though it was at 14.7 to air fuel ratio... which is not safe at all ...
very promising ,estimate power from that terminal at 185/190 . :)

Did you have to rebuild or replace the turbo at any time this year?

There seems to be a consensus of opinion that the Gt17 is not as robust as the T2/3 or is it just people having trouble with rebuilding them. Maybe just my imagination.

Hi,
From what I read, people on here seem to think balancing is essential after rebuild as the core assy is lighter and therefore more suseptable (sp?) to out of balance problems...
Cheers,
Gavin :)

I would say balancing is a must, and the fitment of a dump valve aswell!

Ok chaps, I am officialy a lazy twat and can't be arsed reading through 9 pages of technofobia.

How the fuck to you seperate the exhaust housing from the cartridge? Is there anything else to be removed other than the four bolts and the clamp plates? I am currently soaking the join in PlusGas, but its not going to budge.

Just asking before I put my elbow behind it and give it some force. I dont think there is, but want to be sure before I break it any more than it already is.

My goosed GT17 simply came apart when I removed the four bolts, the decent one is a real pig and after weeks of abuse & cans of plus gas I still can't get the dam housing off.

I had to give mine a hefty thump with the BFH to get it off.

Hit the lumpy bit on the flange to get it to rotate first.

Then file the damaged flange flat afters :$
