Soooooooooo.. I recently learned today that my good old NPI intake manifold has cracked and its leaking coolant. And then I also noticed it has an aluminum crossover..

Does this mean that it is car already has a replacement manifold? I know that crossoever is suppose to be plastic.. But it isn't. Fantastic. Anyways i was looking at what options i had like the PI intake swap onto NPI heads which seemed a little risky considering this is a daily driver in the summer. Should i just get an OEM replacement? I don't even know if they make NPI replacement manifolds and there seems to be no aftermarket options... Is the PI intake swap reliable? I could do it properly people seem to be skeptical about it. Or should i save up and do the entire H/C/I swap, could i do it for under a grand? I am pretty new to these mod motors (385 series FTW!!) so i really dont know what im getting myself into.

I THINK if you have an alm crossover you have PI heads as well.

No there are NPI replacement manifolds with aluminum crossovers. Its not that fast ahaha. Im just ticked off that its gone through 2 manifolds already.. What was ford thinking. Why isn't the whole damn thing aluminum...

Gotcha.

I just bought a alm manifold for my 00 and leaking under gasket

If i am going to all the effort of taking this stuff off. Should i go ahead and throw in the PI cams? Ive researched this so called Anderson Tool and i looks like a piece of cake. Its just im not too familiar with lash adjusters.

there are a few aftermarket setups you could buy and some others. theres PI intake, the bullit intake is really nice but for the whole thing it will cost 600-800. theres also ones like trick flow, edelbrock, and professional products. I would just throw a PI manifold on there. its not any less reliable than npi manifolds and does let the npi motor breath a little more.

So i have heard. Are there any issues getting it to line up with the stock heads? I havent really seen a good explanation of what gaskets to use. Most say use the PI gasket and place silicone on the water ports. And i was thinking since i have alot of the top of the motor apart. How much more would it take to throw in the PI cams. I read the article on the Anderson tool and it looks really easy. Just the fun of taking the timing cover off. Do the lash adjusters pop right in and the rockers torque right on to them?
EDIT: oh apparently i don't even have to take the timing cover off! Im just not familiar with lash adjusters thats all haha.

There is also the Zeus / svo intake but they are hard to find. If you do an www.allofcraigs.com search you may be able to find one that way. You could also look for an svo supercharger to use. Both the svo/zeus and svo supercharger bolt directly to either the stock npi head or the aftermarket svo head.

ya ya ya. try to find the svo supercharger to bolt to your heads. that would be a sick set up. also ya you could use the pi intake gaskets. also it wouldnt be difficult with everything off to do the pi cam swap. the lash adjuster(lifters) just slide right into pockets in the head and the rockers sit underneath the cam lobes and then on top of the lifters. there not bolted. its a pretty easy setup.the cam swap you would just need to pop off the valve covers. unbolt the cams and swap em out but ofcourse keeping the timing by either swapping over the cam sprockets or timing it. but as far as intakes do some searching and find the svo supercharger.

go for a typhoon manifold if you can..i love mine and its all aluminum so its pretty durable plus you can use all your stock hardware on it..

I dont think im going to find one lmao they seem pretty rare. I think im going to go with just a PI intake. Will there be any difference in stage one comp cams over the regular PI cams? Because im thinking i shouldn't bother shelling out the cash for the comps if i can just get PI mustang cams for dirt cheap.

[MustGT98allday]

there is a difference in comp 1s over pi's. a pretty good upgrade and with the comp 1's (262's or whatnot you can get away without changing the springs and retainers too. if you go bigger you will definitely need to upgrade your valve springs/retainers. if you do cams and the pi intake you will definitely not be disappointed. and youll still have the low compression to throw boost at it. dont forget if you do the pi intake you will also need the pi heater crossover tube that runs from the back of the water pump through the valley of the block to the back to one of your heater hoses. the pi runs off to the side allowing room for the larger intake.

Yeah i have read many writeups on the issue and it seems pretty straightforward. Those comp cams are a little pricey though aren't they? And i would need to get that special ford cam gear tensioner as well. If you have that it seems like a walk in the park.
