Outer Limits 4x4 Board

Hi all

What is the biggest turbo you can mount on a Denco exhaust manifold, before the comp. housing hitting motormounts/frame etc...

My truck is a 1-HDT factory turbo, and my plan was to use the turbo I bought some months ago, a GT3071R with ext. wastegate, and make up an adaptorflange CT26-T3, but ditched it because of limited space.

So will just buy a new Denco manifold with T3 flange and get the biggest turbo that will fit on, so that is why I ask the OL experts

it may depend to some extent which vehicle and which manufacture date - early 80 series have a big engine mount on the right to cater for different engines, and can limit turbo size.

Using a T3 flanged denco manifold and the T3/T25 two piece adapter plate i was able to fit the GT2876R which is physically quite massive.

The 4" inlet did come close to the back of the alternator but it clears just enough.

Thanks for help

My truck is manufactured late in 94.

Does this T3/T25 adaptor plate "steal" a lot of space , did you made one by yourself or can you buy it from somewhere.

Is there a 1HZ turbo manifold which allready have T25 flange do you think

Does anyone know what the T3 turbo, that comes with the denco-kit can produce regarding power/torque..

Cheers

Vn15, a t25-t3 adapter is approx 20mm in height. As far as I know there are no manifolds that have a t25 flange. You may have to relieve the engine mount a little to make a large compressor housing fit. We have fitted smaller Garrets with no issues.

The denco kit will have a Switzer turbo in it, an S2 I believe. Pm me for info on the adapter if interested.
