Ok so as I build my stroker(actually I've coped out and decided to buy from Golen) I am ever searching to pinch as many ponies and upgrades to the motor. One of the more hands on upgrades is my 4.7L Dodge Dakota 68mm throttle body conversion.
I have a 97 tj with the 4.0. I've read on the net that if you go with the newer 99+ intake manifold that it will afford you as much as 10 hp stock and as much as 25 hp w/a stroker.. NO BRAINER!.. so i got onto www.car-parts.com and sourced myself a intake manifold from a 03 rubi for 120.00 shipped. perfect... I striped it, ported the runners a little bit (key word: a little bit), and then painted it up with a high temp engine aluminum color paint. turned out very very nice.
Next on the list was my intake.. That was a 81.00 delivered to my door BRAND SPANKING NEW (quality) 68mm TB. SCORE!.. Now the hard part... Mating the TB to the intake..
I went down to my local Patton's metal supply yard and bought a 8"x8" 1/2" thick plate of aluminum for about 8.00. I didnt have to have them cut it down so that saved me a few frogskins.
Then I went home, made a paper template of the mounting surface of the TB, and cut it out. I then made a paper template of my intake manifold's mounting points. I then fused the two together and made one master template. I then copied that template to the aluminum and began my die grinder, air grinder, port kit (left over from an aborted ported head project). i also used a hacksaw to get it to its basic dimensions.. I then bought a holesaw and cut out the center section of the spacer. I then milled out the intake's tb entry hole to match. I then drilled, tapped, and countersunk all that needed to be done..
I then went to the local pick a part and pulled a tb linkage off of a 93 xj(they just bolt right off). cost, 2.00. I got home and hacksawed the nipple off of the linkage and welded it to my 68mm tb. As long as you have a manuel tranny its fine. auto, you'll have to weld the whole linkage to the 68mm linkage.. all of the IAC and electricals swap over.. easy breezy.
with the 99+ intake and the 68mm tb, i can expect to pinch a good 35hp out of the stroker. I'll be putting on some ford motorsport cobra injectors as well. extra fuel in, extra air in, extra exhaust out.. Thats another story(3" exhaust with a fabbed up banks header..
And heres a few pics thus far!. enjoy!
You gotta love the nice lines.. HARD WORK PAID OFF
Picture of the linkage before welding.
It doesnt much smoother than this!
