The cross drilled head is a swirl port head. I have many "G" heads, but they should be cross drilled for turbo use. The turbo is a MHI TE04H. The reason for the Bosch alternator is that the Bosch MPI system requires their alternator. You may have the correct one on your engine. The regulater is inside the engine control computer. The computer was made at Chrysler Engineering before Mopar performance had them. (Thats where I used to work). So you could say it is custom programed.It was the the only modification on the 2.5L turbo in my Sundance. The Sundance was natorious for kicking 5.0 Rustang butt. The quarter mile runs were always in the low 14's with street set up. Drove it to work all week and drove it to the track and raced it. Dan

I think I may wait awhile on swapping to a turbo engine, maybe next winter. I still think a N/A MPI swap would be nice. I just don't know about using a turbo computer. I think the spark and fuel curves would be all wrong and I would get worse mpg with a little more power. I have been looking into mega squirt ECU they seem simple and cheep enough and on the Turbo Dodge forum a guy converted from a carb to mpi on his charger and claims to get 40mpg.
I also found another guy who converted to MPI using his stock '94 tbi ecu in his Daytona ( http://www.cardomain.com/memberpage/256160/4 ) batch firing all the injectors out of a ford 5.0 together. I don't see much benefit in his conversion though.
I am thinking of just using a Mega Squirt ecu with a modified turbo ported intake manifold, a header, ported head, raise the compression and a better cam to make 150 hp. If that is not enough I could give it a shot of nitrous. How does that sound? I really can't decide if I want to build it N/A or turbo. Both have there advantages and disadvantages for street driving.

So your sundance ran low 14's non intercooled? Wow that is pretty good. Was that computer was not avalable to the every day person? A bosch altenator will not work without the computer to control it then? and vice versa?

The computer was a one of a kind. It has a removable EPROM so we could tweek it. We also made one for a 3.8L V6 with a turbo. That ran good too. The Bosch alternator will work if it had a seperate regulator. It is just that Bosch included the regulator in the computer curcuit.I don't know if they still do it like that now. When Chrysler was developing the turbo engine, they were dealing with Bosch for the MPI system that was used on the Porche. Bosch said it was manditory to use their alternator because the Chrysler unit was too "noisy" for the sofisticated electronics in their computer. GAG,GAG. I personally think they are full of sh!t.
We,at Chrysler, made up a MPI system and demonstrated it using a 318 engine, but Chrysler management said they were already comitted to the Bosch system. What does "kick back" mean? Dan

You can go to 4x4dakota.org and see the Sundance in my photo gallary. Just click on my title (DAHEMIKOTA) and then click on the gallery icon. The pics are during the chore of putting a 360 in it. Also got a 69 Dodge van that I moved the engine back 30". That one would surprise people. The engine is a 370 inch small block Chrysler. The engine picture is looking in the side door behind the front seats. It would get about an inch of air under the front tires on a hole shot. Dan

Holy crap 360 in a sundance? That little thing has got to fly. Looks like it fits alright. Is that the same sundance that had a 2.5 turbo? So have you gave up on the four bangers then? That van kind of reminds me of the Little Red Wagon wheel stander.
Did you drive your turbo Dakota on the street at all? I was wondering what kind of street manners a 2.5 turbo would have in a dakota and how it would handle towing a covered 2 place snowmobile trailer. Right now my dakota is lucky to do 55 on a windy day with a open 2 place.

That was the turbo car. I went to change the fuel filter one day and found so much rust under the rear end, I was going to junk it. Instead I tubbed it and put 2x3" frame rails from the firewall to the rear. Then put an 8 3/4" narrowed axle with four link and coil overs. I made a cross member like the one Direct Connection made for the Daytona V8 swap. I used a Dakota rack and pinion and swapped the spindles side for side to get a front steer system. I made a 1/2" aluminum motor plate to mount the front and made a cross member for the 727 TF mount. A little trans hump work and a drive shaft tunnel made it all done. I took it for a run on the street with expired plates. I got caught. The cop didn't give me a ticket. He bought the car on the spot. I don't know what it would do in the quarter mile, but I think it would kick the vans' butt. The Dakota with the VNT Turbo was like driving on wet pavment. I had to be carefull. At 40 MPH,in fourth gear,pushing the pedal to the metal would bring the rear end around. After some practice,you could keep it going kinda straight. With the standard 2.5L mitsy turbo it's not so aggresive. The mitsy takes more time to spool up. When the boost comes in, you suddenly have a V8 in a little truck. If you drove it sensibly you shouldn't have any problems pulling a trailor.I would say it would be like pulling your trailor with a Dakota R/T if you don't go nuts with the boost. Dan

I thought the mitsy turbos spooled quicker becouse they were small they just didn't have the top end like the earlier garets. Wow a VNT those are rare arn't they? Does a VNT spool even faster then a mitsy? Maybe I could set up one of those granger valves like a friend of mine has in is '88 Lebaron convertable with a 2.5 turbo. He has wired to a switch where he can run 15 lbs or switch it back to stock. How much boost would be nuts? What did you do for traction in your dakota? I was thinking caltrak bars and the 17" by 9" rims and tires off the R/T dakotas.

The VNT stands for Variable Nozzle Turbine. The nozzles direct the exhaust gas into the turbine to eliminate most of the turbo lag. Trouble is when the boost gets up, the exhaust volume increases to a point that the nozzles backing off can not slow down the turbo. It just keeps increasing speed untill something bad happens. That is why Chrysler discontinued the system (Turbo IV). The cure would be to install an after market waste gate or an air dump on the intake side. It would cost too much. A boost of 15# is kind of pushing it on a stock motor. My motor had "O" ringed cylinders and head studs. I also had forged pistons. The traction system I used was a copy of the Mopar super stock rear suspension.I added half leafs to the front of the springs. A little more spring rate on the right side. You have to play with it to get it working good. The vehicle weight and wheel base have an effect on body roll. Also I put 90/10 shocks in the front to get the front end up fast for weight transfer.Sorry I took so long getting back to you. I just got back from Tennessee. I am moving down there. Sick of Mich.

Yeah I knew what VNT stood for. Chrysler was the first to put one in a production car I belive. I didn't know the VNTs had any problems though. Well my friends lebaron also has a intercooler installed so it is not completly stock.
What about traction bars do they help at all on a dakota? I have heard Caltracks were good and was thinking about those. Oh and have you checked on what the price building a header might be for my dakota?
Moving to tennessee? Must have a good job or friends and family down there.

If you run stock springs, traction bars are a must. The Mopar super stock setup stiffens the front of the spring so it can't bend. The header price is for steel header $250, For 304 stainless steel $450. They would be 1 1/2"
primary tubes X 30" long with a 2 1/2" collector X 6" long. I am moving my shop down South. I have a friend that lives there but he is about 40 miles away from my new place. Dan

Oh so the super stock springs don't sound too good for the street then. The header sounds perfect. That is just the specs I was thinking of but dang stainless is expensive. Maybe steel would work just fine. I just need to decide what I want to with the intake manifold and ecu. Go the easy way and port the stock TBI intake. Swap in a modified turbo intake and turbo MPI injection system, or an aftermarket ECU like megasquirt. Sense I am a beginner I think maybe I should just stick with a ported TBI intake. Do you do any porting work or know of anybody in Michigan that does a professional job.

They are OK for the street. The ride is just stiff compared to stock springs. I also replaced the bushings with bronze to eliminate any side movement. You could feel it if you ran over a dime. Just the way I like it. I can do the port work but I don't know when this place is going to sell. Did you want to do a "G" head? I may have one that is done with the cross drill for turbo use. It would also have the turbo valves in it. That way you would not have to change the head if you did put a turbo on it. Just the pistons and rods. I am taking my machine shop down South with me. Dan

Yeah way to stiff for me I already have no traction in the snow and mud stiff springs would not help any. I was considering the polyurathane bushings for my pickup. No I don't think I want a G head I will stick with the stock swirl port. Do you know if the tall deck 2.5s were put in the '87 and '88 dakotas? Or was it just 2.2s?
