hello Dodge talk, I am new to this site, been messing with Hondas for a little while
but have seen the light!! I am going back to a V8 RWD platform
need more tourque!!
heres the plan, put a 402 Crate motor in my dads old 1990 2wd 2.5L
Dakota, the thing is I want more than 435hp, and would like to use
a multi port FI setup with forced induction, centrifical supercharger
most likely, so the question is... who makes such things, I need a good
MPFI system, the electronics to run it (obviously) and some direction
on a supercharger setup, if It is in your opinions better to just stick with
a carb, then please enlighten me, and if I do use a carb, what kind of
super am I limited to?? (screw type manifold I assume)?? I know theses
are prolly some general type questions, but like I said I have been
playing with a Turbo 1.6l honda, (wich is for sale BTW) any suggestions and
advice is much apreciated.... Thanks in advance

I may be a little out of date with current Crate Motors...wasn't aware of a Dodge 402 version.
Well, sounds like you have a pretty ambitious project ahead of you! 435hp should be doable (how the heck did you come up with an odd-ball number like that anyway?) with 402cid.
I would start with talking to Dodge themselves and see if you can get any contacts for those people how have bought that motor before and what they have done to it. Even if they did something different, they would have been in contact with people who supplied them parts for the motor which would be of great help to you :)
Good luck! ANd keep us informed!

Welcome to the site DAcrate A!
That crate motor is based off of a 360 block correct? If this is the case does it still have 360 magnum heads on it? If this is also the car you can go with any 360 magnum topend(intake fuel rails, TB etc etc...). You could also upgrade to a stuff(IE:M-1 intake, bigger TB bigger fule rails etc etc...). Then if you do go this route you can use just about any S/C setup from Paxton to Vortech, to a Kenne-bell if you would like. ATI is the only one out right now that is producing a kit with an intercooler. Just some thoughts! I hope that helps!

itisbasedon the 360, its a 4.00"bore x 4.00" stroke I belive. It comes with the RT heads, 2.02" intake and 1.6x exhaust (I for get the ex # exactly) bassically my concern is if the standard 360 MPFI setup is enough for what Iwant to do, even with a bigger TB, are the plenum and runners big enough? and will they work with the RT spec heads? I am going to call Mopar performance and ask, but just wanted to see what I could learn before I do so. so they do make an M1 intake for MPFI applications?? also... is it possible to run the distributorless Ignition system in this app.? Iknow I wouldhave to install a crank sensor and the electronics, but I figure that would increase the tunability. (is that aword??) thanks for the replies...keep em coming if you have something to add...

Yes they make the a MPI M-1 for the MPFI setups and it should be able to handle what you want it to do.(alot of Dakota R/T guys run the same setup you want on there 360's and 408 storkers) I dont think the basic "beer barrel" MPFI will work but the M-1 with some FMS 24 or 30lb injectors and maybe some holley fuel rails will work! You will also want to run a nice aftermarket TB. I am running a Magnum Performance TB on my truck and I am very pleased with it(55mm)! It totally changed the performance level of my truck! The only down side to MP is the customer service and the poor management. I say if you can get a good second hand MP TB like I got go for it other wise you might waht to look into F&B TB's as well as Fastman TB's. The M-1 will bolt up to the R/T heads.
I dont knw about switchin to a dstributorless setup....I personally like distributor setups and I think they are easy to tune but that is just me.
As for S/C setups you may want to go with a centrifugal s/c for the tuning. I have heard horror stories about the kenne-bell system and its tuning.
