i dont expect to hit 250 hp while in 4wd lol id just like to have 250 at the crank and yeah thats what im hopeing for is lots of low end power and i just talk to the guys in our shop here at work and they said they may know of a buddy of theirs that could do it ill talk more with them at lunch but if so then im on the right path

O I wasnt referring to ""in 4wd"" and crank means nothing, its what makes it to the ground.a transfer case EATS hp especially if its a a4ld trans.your hit 250 at crank but no way for you to know that unless you dyno the engine alone, but you wont hit 250 to the ground.

You will have good power though and it will seem wayy more which is more important than a number in my book.ask your buddy or shop if they tune the sct elimnator chip for obd1, if they dont know what that is they dont tune it..best places to start is places that tune old fox body mustang, they use same chip and tuning is VERY similar to the ohv.my base tune was based off a old mustang and was very close.

What kind of m90 or kit is it?

All of them are eaton m90 but they make a bunch of different models. The one in your picture looks to be a rpcaster kit(ford thunderbird m90)you can use photobucket to upload pictures.

I did post links, you most have missed them ;)

Chip, where I got mine but you need to request that it come blank with no tunes!!!!then you need to have a dyno shop write you a base tune to get the truck to the dyno, then have it dyno tuned

yeah i believe its very similar to that kit but this is meant for the OHV idk but if you can see under the intake that piece on the bottom is the fuel rail and oh yes i much have missed those links so those three are more than likely what ill need for this and a good tune of course

He makes a kit for the ohv.member DONO that posted in this thread runs it.problem comes when you start building alot of boost, basically over 5lbs your need a intercooler or water meth..rp does make a intercooler and """"belive"""" someone on here has one for sale or not in use..

Those are the most used and common parts.your also need a wideband O2 and injectors, obviously. But again I would ask you tuner for injectors size.DONO and I both run 36 and have good idle/cruise. I was running 10lbs, will be running 16

well, i have dono's intercooler from his setup, and i wont be using it when i change blowers. i have promised someone first crack at my setup with the intercooler, but his plans may have changed drastically and i am not 100% sure if he is going to be buying it at the moment.

^^ it says under your name that you live in Selkirk, Manitoba which is one hell of a drive for pick up or a pre decent cost for shipping as i am assuming its a fair size being a intercooler

What kit/mount are you using?? Should come with a custom intake manifold or a tb that has one built in like the early mustangs...
