NeoTokyo

Whelp I am back. I took a short break because we sold the Z, then it swapped hands three more times only to come back to us with a blown motor and torn apart. Pure luck let us find her again, Love for this Z will bring her back to life. I guess I propelled a lot of this "Coyote Madness" in the beginning so I should try to at least do this swap. If I can get ahold of a crate motor I will of course make a detailed YouTube 1080p documentary with a Canon 5DII for high quality 1080p eps on how it was done and how everyone else can do it. I am going to try my best to hunt down a Boss302 engine with harness and controller but I don't know if Ford will sell one yet. With its 440hp rating, CNC'ed heads, lighter-stronger valve-train, sodium filled exhaust valves and stronger forged rods/pistons this would be a great match for a Z and tuning. Lest we not forget the more aggressive cams, tuning and short runner intake to take advantage of the CNC heads new flow. The electric power steering might be interesting to incorporate into this build as the Coyote, Boss or Not has NO prevision for a power steering pump. The 6spds hydraulic clutch ought to be a cinch to hook up to the factory Z hydraulic system with minor modifications and hardware. PST is my company of choice for carbon fiber drive shafts and that's who I will go through for the custom unit that I will need. If I can get my hands on this engine I will have Evo Perf help me with the LT's and full 3" exhaust, C&L for the CAI (Custom thanks to the Boss's new intake) and Jon Lund for tuning. Pretty much the big players in the Coyote's release. I will also try to get ahold of FRPP's roots SC for the Coyote as a coup de grâce finish to this build. Of course Suspension and brakes will be along the usual Z variety. Right now the biggest hurtle that I have to jump is getting this motor and finding more funding. Lets see what I can do. -Eric-

Abaco makes an awesome, tunable MAF. http://www.abacoperformance.com/products.htm

Well what about the 6.2L SOHC that will be in the 2011 F150 Raptor? Even the 5.4L can be sleeved and stroked to 6.0L. Granted these are wider engines, and heavier with Cast Iron blocks (aside from Aluminum 5.4L blocks) these are still great performers and are on par with most LSx engines. Now I cant say that the High CR 5.0L can take instant boost, infact I highly doubt it can take more than 4-6psi on 91oc but that has been the current trend since about 1993. Boost has varied in GT's along the years based on many variables from fuel used to stock compression. In the 94/95 GT there are people running around with Kenne Bell Blowzilla's pushing 8-10-14psi on stock internals. Pistons have been a weak link in the GT's (Among powdered cracked cap rods) since 1993. Cobra's of course get better parts. This isnt gospel as there are many exceptions in building boost on a stock engine. Octane is also a limiting factor, E85 is becoming very popular as it is 105oc and has a nice cooling affect. It does however have a downside in that it takes 40-50% more fuel to make the same power. You also need an updated system that wont be harmed by this fuel. The last 5.0L's to be used experianced core shift at 500+rwhp and started to fail, so many times it wasnt the internals that failed but the block itself. So you are right in that we just wont know how good this new engine is till people get their hot little hands on it and start pushing it to its limits. Matching this engine with forged rods and forged lower CR forged pistons will make a boost beast!

I read some good news today; Ford HAS used pressed in Cast Iron liners in the new 5.0L Coyote. This info is from a Ford Press release. For me this is great because now we can bore this engine when we stroke it. We can also sleeve it now too; before when I read that it was a sprayed in liner that left some doubt to as how much meat there was in the sleeves. If there was a sufficient amount of material it could have been sleeve, but no need to worry about that now.

Well 281ci is rather low but they do very well none the less. The new 5.0L engine is a step in the right direction. The 330ci 5.4L is the next best thing, but it is very expensive to get an aluminum version of this engine, the Ford GT (SuperCar) being the absolute best version of this engine. This is also a larger engine and I dont know how well it would swap into any Z car. Now for next year (2011) an all new 6.2L will be offered in the SVT Raptor F-150 that is said to offer at least 500hp. It will be an SOHC design but if this is a mod engine (And it is) You will be able to slap a set of Ford GT or GT500 heads on it and have the largest DOHC Ford Mod motor around. You will of course need a custom intake for this or just Supercharge it, but I am betting that the CR is going to be pretty high on it. I am also betting that the 6.2L is going to be a Cast Iron block instead of an Aluminum design, but I really hope and wish that it will be aluminum. Ford is catching us with the cube race, but they are also showing that they dont need to be the biggest as far as engines go to make similar or more horsepower. As long as we dont see some really bad stuff going down Dec. 21st 2012 I think we will end up seeing a 6.2L in a GT500 by at least 2014.

True but the Mark VIII block is the same as the 96-98 Cobra block, the 96-98 Cobra block also carries an 8 bolt forged steel crankshaft where the Mark VIII is a nodular iron 6 bolt crankshaft. These block when prepped correctly can sustain over 1200hp, but thats the catch, you need to prep and build the block correctly. This block is also 5lbs heavier than 99-04 aluminum DOHC blocks which is why it is so much stronger. The thing with Ford aluminum 4.6L's is that they need to be built on a jig fully dressed otherwise clearances change. SHM discovered this in their pursuit for perfection when building this engine. Its best to leave them in stock form if you buy a crate motor or low mile motor if you are on a budget or dont plan on going higher than what pump gas can sustain. Even the 10.65:1 CR 03/04 Mach 1 can be low boosted via either Roots SC's, Snail SC, or TT and make about 500rwhp with proper tuning. Of course this is with full bolt ons. It is best to use SNOW PERFORMANCE products when using forced induction. Even better is to run E85 as it is 105 octane. You will however use about 40% more fuel to reach the same power numbers though but you will have a detonation free (If tuned correctly) High power engine.

Where did they get 30" from for the DOHC 4.6L? Its 26 5/8" from edge of valve cover to edge of valve cover. Sulivan Performance has the specs there (Big name with Mod Motors) and I have an 03/04 Mach 1 Crate motor sitting in the garage (DOHC 4.6L) The VH45DE is just a little wider, just over 26 3/4"

You could just buy one of those custom fab kits that you press together and then send in the finished version to the header company of your choice to have them custom make it for you. Its expensive but it works.

The ECU will be just fine, you can also get the wiring harness, pigtail behind dash harness to the ECU and ECU from a 96+ Explorer 5.0 and modify it to work with your 5.0L and thats it. Now you are running a safe and easily tunable OBDII ECU instead of the 94/95 OBDI. Thats not to say the 94/95 OBDI ECU is bad, its just not tunable with a hand held tuner like a SCT or Diablo unit.

True true, 2 cams are much easier to pay for than 4 not to mention if you want to upgrade the entire valve train from Jesel rockers to valves and springs, 16 is a lot easier to pay for than 24 or 32 Head porting also is much cheaper in many cases with the 2V and 3V SOHC heads than it is with the 4V DOHC heads. Thats about where the cost differences end, the shortblock is fairly identical between the three with only minor changes such as valve reliefs in the pistons, timining components and so on.

Nah, John its ok, similar posts happen. Extra imput is always good and a forum wouldnt be a forum without people posting. The Coyote is an exciting new engine and its on most of our minds

Por-15 ftw

Does anyone have any pictures of mounts for a Z32 of any non VG30? I would like to keep a photobank of different mounts.

Idle Air control seems like, clean it out and see if it helps as it can cake up pretty badly. Make sure to get a new gasket for it. It can also just fail so you may need a new one. Also use some MAF cleaner and clean the MAS. Do your reg maint on it from plugs to fuel filters, its good practice anyways just to do it all at one time. Good luck. -Eric-
