Sidewinder turbo kit

[jwindbigler]

I am in the middle of rebuilding my 89 F250, and I wanted to know if I needed to lower the CR to run higher boost like normal cars. I plan on boring out the cylinders .030" over, and I wanted to buy the sidewinder turbo kit, put on a custom innercooler and raise the boost a little bit more for better hauling capability. Any help will be appreciated. Thanks

dont know what good it is to you? but there is an 85 with a 90's 7.3 diesel with the sidewinder already on it for sale in colorado. not sure where you are at tho.

I think the CR on the IDI is around 20:1. The sidewinder is designed to run with that ratio. If you want more pressure out of it, you need to talk to Banks to see if the turbo will supply it. If you want high boost numbers, I would lower the CR, but you made need a bigger turbo and a modified injector pump to supply enough fuel to make the combo work.

Check with these guys, they may be able to help.IDI Products

Do you know if you can innercool it though?? Also is there anything that I would have to do to tune it after I put on the turbo, or is it just bolt and go?

I still am pretty new to the diesel world, so I just want to make sure that I do things right. Thanks for the advice...and no, I really dont have a use for another truck with one already in it. Thanks.

An intercooler would be great. All you have to do is bolt everything on. You don't have to tune the engine like a gasser. The diesel will love the extra air, and you will be able to add more fuel for more power. Just make sure the intake and exhaust are adequate.

[jwindbigler]

Make sure intake and exhaust are adequate...what exactly do you mean by that?? Do you mean that I need to have a good exhaust system to handle the intake system?? Make sure that I dont put in too much air? Just not really sure what you mean.

How does the hypermax turbo compare with the likes of the banks turbo?? Do you get the same or about the same power and fuel economy?

Here's another question...if and when I do innercool it, should I expect to see a raise in fuel economy??

I have the Banks kit on my '94 IDI. It is a very complete and easy to install kit. With the banks kit, you are not able to intercool it due to the cast housing on the turbo. The techs at Banks claim it does not need an intercooler but I don't know if I agree with that. I don't know anyone who has the Hypermax on a truck so I can't comment about that product. The Banks turbo does make good power, although there are some tweaks that need to be done to really turn the wick up. In regards to the intake and exhaust, both need to be very free flowing. The intake air should be as dense/cool as possible. An engine is nothing more than an air pump, the more air you can get in and out of it, the more power you will make. My truck with the Banks kit would outrun my friend's '97 PSD when it was stock. He upgraded his turbo, chip, ect., and I added propane and I can still keep up with him. There is alot of potential in the old IDI trucks.

I understood how the engine is basically an air pump...breathes the air in and spits it back out. I just wasnt really sure what he was saying.

I definately want to innercool it. It just doesnt make sense to me not to. I guess that I will have to be the first guy that you know with the hypermax kit. Assuming that it will allow for an innercooler. Thanks for the help.
