MASSEY 290 Turbo choice.

[shumungus]

Rebuilding an MF 290 and going to put a turbo on to give it a slight lift as it is just a little underpowered for slurry mixing. Don't want to get into the whole to turbo or not 4.236 better suited thing, just trying to figure out what turbo to use. Have sorted oil cooler and filterhead and exhaust and manifold will be straight forward but want to get turbo sizing and type right. Anyone out there know what turbos were used successfully back in the day?
TIA.

I think a lot of them used opico turbos

Holset turbos were the ones we had from Tb turbos [long gone now] ,590,690 and the 6160 were all turboed. The 290 here was a relay good one punched way above its weight ,when we put the turbo on the 590 with 1200 hrs on the clock the service manager nearly had kittens ,"thats like asking yer granny to run a marathon" he said ,it was just over 9000 hrs and still a powerhouse when it was sold. Their should be specs available as to the optimum size of turbo for a 248 engine.

Any idea where I would look for specs? Plenty for 236 engine as it was commonly turboed but can"t find any for 248. Even sent an email to Garrett, no reply yet.

On the Jcb parts that comes up as the 4236 engine using the Mitsubishi turbo which has no wastegate or regulation, but I will give them a shout as they are only 10 miles down the road from me.

I'd go for a turbo with a Westgate valve on it. That would give you boost at lower rpm, and not overboost the engine at full load. Without looking it up, your engine is around 4 to 4.5 ltr capacity? A westgated turbo for a Perkins 4 cyl 1000 series should be fine, just get an adapter to Fit it on to the exhaust manifold. And plum the oil inlet etc

 

[john432]

Yes 248 cubic inch is 4000cc near enough.

Was thinking on the Garrett turbo from the 398/390T as it has wastegate and roughly same engine size.

It might worth a phone call to P V Dobson at Kendal they would be knowledgeable on Perkins engines.

Search 2674A200 it's the Perkins part no for a turbo for a 1000 series, I've one here to fit onto a Renault when I get around to it. Bought it cheap off eBay brand new. But a copy is on there now for £265

Garrett gt2052s from the 4l perkins 1000series with the 0.48 ex housing be a very good choice. As used on the 'hi torque' spec engines.

 

[john432]

Put the part no into Google, are you in the UK or the Republic? Might make a difference?

How do you know when buying if it has a 0.48x housing and what does that mean?

0.48 is the aspect ratio or a/r and its stamped on the ex
housing

 

[john432]

The one I have is 0.52, is that ok?
