Has anyone ever rebuilt a T2 successfully at home or in there garage and does a T28 turbo bolt up to the T2 exhaust manifold.

[RS EDDIE]

Wouldnt advise rebuilding a turbo at home mate, they are balanced to 120,000 rpm, so unless you have got a tool that can do it and measure it microscopically to that tolerance then ....NO NO!!!

Not 100% but i think a T28 does bolt straight in....

[MK4 Rick]

Im sure some one told me a T28 bolts straight on but i carnt remember who

[andymac]

T2 / T25 / T28 all use a t2 flange and will, compressor housings allowing, bolt on.

Be aware some variants requires an oil feed restrictor.

That's handy to no mate I have a T2 exhaust manifold and T2 turbo for my 2 litre blacktop but im thinking I might need something a bit bigger like a T28.How much bhp are the T28s good for im talking about a turbo that's just std and not modify in anyway.This is all to bolt into my mk4 From what I can gather I can use a 1.8mm head gasket on the blacktop to lower compression.i think its a triple layer metal gasket.

I've heard of T25's pushing over 250hp - but it's about efficiency gains at the top end with a T28 (better static pressure and lower temps owing to larger compressor wheel). I don't think approaching 300hp is out of the question, but I also think it's likely an uphill struggle given the size of the flange on the hot side.

More depends on the spec of the engine, how effective your intercooler is and how well the engine will be allowed to breathe on both inlet and exhaust (note the t2 flange is quite a bit smaller than a t3 flange).

EDIT : See http://www.capa.com.au/turbo_garrett.htm for more info

EDIT 2 : T2 will run out of puff quickly on a 2.0, t25's can be had new (recon from turbo technics) for in region of £180 (they had one or two on a special at that price recently, normally aorund £450)

Im not after setting the world alight.Ive got to be practical on this there is no point in the tyres spinning if im going no where. I was given the manifold for nothing so I carnt grumble.The 2 litre is giving me problems with torque steer now and that's just n/a

[andymac]

Really? Do the lower arms match, bushes in good condition? I wouldn't expect much in the way of torque steer from a 130hp nasp engine.

To be honest ive not had time to check them Andy I only put the engine in the other bank holiday week.

[andymac]

Fair enough!

I'd have a poke round if it's pulling about a lot, and check you have matching lower arms (I've known some cars have mismatched pattern arms due to previous owners being a bit skint, tight or lazy).

[MK4 Rick]

Think I might have found why it goes in another direction I was staring at the wheels today and noticed that the rear tyres and drivers front are 185/55/14 and the passenger front is 185/60/14 think I might go from there

[andymac]

Oops! LOL!

Having said that, when I bought the Rover, it woudl pull to one side on accelleration without fail. Correct size tyres, same type.... but the tread patterns were slightly different - one odd tyre on nsf (despite being "same" as others). Guess the pattern had been revised at some point and it'd had one new tyre on, screwing it up.

I'm coming in late on this and haven't ready the replays but I have rebuilt a couple of T2s at home, and my best advice to you is don't waste your time and money.
The worst bit about the T2 is the oil seal groove wears and although you can get over size seals if its worn too much the shaft is no good and needs replacing, which means it needs balancing to the compressor wheel, which 99.9% of people
Can't do at home.
As a engineer, as well as my dad being a engineer we do have a engineers table and knife edges etc but that's basic balancing and I wouldn't even trust it spinning up to the rpm they do.

Leave it to the pro's fella

[andymac]

.Leave it to the pro's fella

Couldn't agree more. Static balance is quite different to the dynamic balance a turbo specialist will do, a few people advocate the "mark and torque" method of getting the turbo back in balance, but in truth even a few mg out of balance would could undesirable results at 10k rpm...

[MK4 Rick]

Ive changed the wheels from the std si wheels to a set of mondeo wheels 195/45/16 and it does drive better.I took it for mot today and it passed with just a advisory on the bushes in the wishbones.Ive bought some new wishbones and drop links today and im gonna fit them tomorrow

[andymac]

Top job!

I've spent the day resealing my inlet, replacing a burst hose, torque control arm and some missing bolts. All kicked off because of a vac leak that now appears to be a poorly sealing injector o-ring.

Is it sorted now Andy

[andymac]

Nope, I need to order the rings in; not paying £3.50 each though that Xpart want.
