Hello all!
my name is John, i am here because theres a wealth of information to learn about the gt40p motors here. from what ive learned stalking the threads, theres a bunch of you guys running turbos, which is awesome. Hairdryers FTW
that, and i had a black 94 4.0 5 speed. still miss that thing.
anyway...last summer i installed a 80k explorer gt40p motor in my '89 xlt...fullsize bronco...a sorta labor of love.
i hydrolocked the stock motor so badly that the rod tore through the oil pan, smacking the starter and cracking the trans bellhousing...anyway
the next day i was at the local junkyard shopping for a stock mustang 5.0, standing in a sea of motors,when i saw the odd 5.0l with coil packs. Something clicked, reminding me of the dozens of gt40p builds on corral.net and other sites, praising the motor's gobs of torque.
fast forward to august, and the bronco was back together, swapped from an automatic to a bulletproof 4 speed manual, manual t-case, and most importantly, the explorer 5.0 -bone stock with 1.7 roller rockers and a cleaned up intake. the bbk mustang headers i had in mind were unable to clear the new 4 speed bellhousing, so in a desperate situation, i used the stock explorer manifolds nevertheless the results were great.
(right after swap)
a few months later after talking to a explorer owner, he told me just how restrictive the stock manifolds were. he also told me the stock cam was garbage. So i took some of his advice to heart and threw swap meet bronco gt40p specific headers (a hard find) on and the difference was substantial. so far the best time in my 4900 lb bronco, with 33's and starting in 2nd, i got this thing to a 16.5 @84 mph averaging 5 runs with the gtech, none more than 16.7-- not bad for a off road brick with stock 3.55 gears and ultra wide shifts!
so next the stock explorer cam, truck intake, and (possibly) fi may be scrapped for a h.o cam 4 deg advanced, ported xplorer intake, maf a9l and some nitrous... i want to get your suggesions on a cam and intake for this sucker. It seems crazy, but beating a stock gt in this brick would be an awesome recipe for big grins and thats what im shooting for.
furthermore, i figure you guys would be much more helpful than mustang guys heaving around a fraction of the weight we do
anyway lemme know what u guys think and thanks in advance.
