Mr posty been busy again.
Going to get the bearings in and the gearbox cleaned up.


And a friend dropped in this morning to loan me a press.

Check the height of the engine mount before fitting compared to the old/original ones.

 

The newer ones can be different in size (shorter mostly), which can cause the engine to 'sit' on the front/back mounts too much overloading those.

 

Should be a few threads on here about this issue experienced by several people.

 

Bye, Arno.

[ditonics]

Thanks for the heads up. Put a calliper across the old and new and all good.

The rest of the bits are on the floor;) Fuel filter, rear HCBs and broken engine mount done.

Bit more done on #64
-side engine mount changed
-fuel filter changed
-several sound deadening layers removed

are you planning on replacing the KKK turbo with a different manifold and turbo?

Long term looking at the gtx2867R.

[chickendippers]

Have you considered a 71HTA instead? Spools faster than a normal GTX28 and makes power similar to that of a GTX30, plenty running over 500bhp on these now and only a couple of hundred more expensive than a normal GTX28.

Has your vxr got upgraded internals?

It will all be going on a second fully forged engine. Long term project.

Still doing home work, will look into it.

holset turbos over anything else on the market

[chickendippers]

Yeah if you don't want any power until 5k rpm.

Out of interest, how come? I noted they seem to be relatively cheap compared to the Garrett turbos, and most seem to be twin scroll. I thought they were generally better for larger capacity engines.  

[chickendippers]

Holsets are mainly from large capacity diesel and tractor engines. They're well built and reliable but on a piddly 2.0L engine they're laggy as hell.

You'd get quicker spool from one of the china copy GT30 turbos from ebay.

 

[Rosssco]

Yeah that's the impression I had of them - they are physically pretty large and undoubtedly 'robust' looking..

I have to say I can't fault my GTX3071, after 7 years it's still going strong. Also my Tial MVR44 was been faultless.

 

Having said that, in your "new build position" I would still consider a variable geometry or twin scroll turbo too.

 

[ditonics]

I am leaning towards a Garrett simply because of their expected long life. They are on the gen2 since you built Nipper i believe. The modern GTX28 67R spools quicker than the gen 1 and has the output of the old gtx30. Long long way from deciding what route to take. Currently pissing about putting the gear box back together.
