KRAYZ Posted March 3, 2007 Share Posted March 3, 2007 Just a update for those looking to do this swap. 1.you want the 99-04 SPI motor from a mustang(or for more cubes a 4.2L from a E or F series) 2.If you have a older 3.8 the intake and heads interchange. 3.the head gasket issues were fixed by the factory by useing MLS gaskets on the SPI motors starting in 1996. 4.In the Mustang the hp was rated@190,but get this the Windstar minivan was rated @200(it has a different intake) 5.The mounts,trans.choices and assy. are the same as a 5.0L,Moderate aftermarket following(cams,ported heads&intakes,headers,turbo kits,superchargers,pistons,rods,rollerrockers,ect.) 6.You get even better engine setbackand you lose 80 lbs. from a stock 5.0L 7.There is a stock interenals TT3.8l making 450rwhp!! here are some links:http://www.vmptuning.com/store/index.php? http://www.supersixmotorsports.com/ http://rpm-mustangs.com/cart/home.php http://www.moranav6racing.com/category.html?CategoryID=16 http://www.3.8mustang.com/forum/ http://www.v6power.net/vb/index.php ****Please keep in mind That other vender links most of the of the banter on the forums is"will this work or how many horses will this get me...But if you look there are some veterens with proven combos.
