4020 turbo

marcusoverholtzer · Sep 27, 2016

Hi guys I need to know if i can put a 4430 turbo and intake and mw exhaust manifold on my 68
4020? Thanks

Use a 4430 manifold set, and a 4320 elbow with a home mad adapter between the elbow and the turbo,, here are some pics of how I do them.. Mail me if you want to know more about it..

Will the turbo fit under the hood? How much hp will i get out of that setup? So i just need a 4430 turbo intake and exhaust mans and thats it? Besides some plumbing of course... Thanks

Put a heat insulator between the turbo and the hood. I did a similar project and the turbo burnt a small spot in the paint on my hood. I used a complete 4430 engine, but I am sure what you propose will work. Like Tim said the 4320 elbow will let you use the stock hole in the hood.

Ok thanks a lot.So my freind with a 4430 says you cant put the 4430 turbo on a 4020 because the 4430 has a 466 and the 4020 a 404 is this right? And tim is that a 4020 in the pictures you sent?

can someone get me correct part numbers for the manifolds for the project? Thanks

The 4430 has the 404 also. The 4440 has the 466.

I believe the 4430 had the 404 not the 466. That is a 4020 in Tim's pic and I think he has done a couple setups that way.

Yes tractordata says its a 404 engine so my freind must not know.

You will burn the hood with 4430 stuff.I ended up using a M@W exhaust manifold,elbow and tubeing and inlet stuff and used the 4430 intake and made a pipe from blower to manifold.If I can get my son to take a pic and put on here it will show what Y did.

Did you use the4430 turbo? Do i need a bigger oilpan?

marcusoverholtzer · Sep 28, 2016

Should I use 4430 manifolds all the way or and mw exhaust and 4430 intake?

Not butting in but published data I found said that my 1960's 4020 engine was 3xx cu in putting out 96 hp. Other data said that my 1979 4230 had a 404 cu in engine and put out 100 hp. The 4430 was just a turbo sitting on a 4230 and it put out 125 hp.

Mean anything to you?
