4.6L Ford DOHC modular motor in my 240z


Recommended Posts

Yeah, Brian's pictures are a great reference. I think on mine (2->1 exhaust, muffler in stock location) there's room to make a battery box that mounts to the moustache bar/ rear diff holder bolts and to the bottom of the spare tire well (also stock gas tank). I'm hoping to finish up my exhaust this week, I'll post pictures if I get my battery mounted up thereabouts.

 

Sounds great...I am on the fence about the exhaust and the tank setup...Do you have a 75 - 76 gas tank?

 

Also I will have to wait till payday to do more...I am tacking up the motor mounts, transmount mounts, radiator brackets, and water neck/oil line adater parts (my way) and then taking them to a professional welder to be done right.

Nope, I've got a stock 78 tank. Get all your stuff together at one time, most local welders charge by the hour, 1 hr min. Cash motivates for smaller jobs though. ;) ($60/hr last time I got some aluminum stuff done a few years back). There's not a ton to gain by going dual, besides the aesthetic appeal unless you're really trying to chase down every last HP. I'm running 2.5 off the stock manifolds and down past the transmission bringing them together with a neat 45° to straight 'Y' off a Chevy truck that exits 3". If I find out exactly what it came off I'll let you know, it's got the y, a nice stainless flex and then an output flange all in about 3'. Should be dirt cheap at a wrecking yard. For a single system, 3" is generally good to 300hp based on a couple of the exhaust mfg's sites. (flowmaster, magnaflow etc)

Thanks for the information

 

I just spent the day with adjusting the motor for the steering rod (which I will be adding another joint) and the mounts...I had some angle iron that has one side wider than the other and when the (2) wide sides are butted up then appear to fit the Z's frame rails perfectly...All I need now is some flat iron...Also had to cut the water/oil adapter on the water side and remove some and reposition the water neck to clear the block and header.

 

I'm taking a brake for an hour and then I will be working on the transmount.

 

I think I will be doing the single exhaust after all. Or maybe I'll change my mind again and again and again!!! LOL

I think I have an solution to the steering and it's really cheap...you get an extra steering rod and a heim joint (~$8 to $12 on the internet or Ebay)

 

Here is the thread where I found the solution:

Glad to be of assistance :)

 

The additional U-Joint that I used was this 5/8 weld in piece from Sweet Manufacturing:

I can't wait to see the 4.6L on the road.

 

I was trying to position everything but it was'nt happening and I saw your solution...

 

Thanks for the awesome info.

I think I have resolved the clutch problem (tremec tr3650's are cable driven). I did some research and spoke with Wilwood about using a pull type slave (part# 260-1333), a clutch master (part# 260-6764), and a brake master (part# 260-8556-P) for my Z32 front calipers and hugh 1" Vented rears with big pads. See attachments (including rear brakes).

Holy Zcar Batman! What is that crazy adapter you have running from the stock shifter location back 8"?? I've never seen one of those. Also, you may want to rotate your slave, so your bleeder is on top of the cylinder (otherwise you'll trap air in the top of the cylinder, unless you fill your system from the bottom and push the fluid to the master...) And, you can remove that chunk of cast iron on the back of the clutch release arm, I dug around on the Ford forums, lots of people removed it, and didn't notice it gone, although it's original intent was to add mass to the system to reduce NVH (noise, vibration and harshness).

These (2) pictures are not mine...And I didn't even notice the shifter adater! I know that many Z swaps could use one. So here's the address (thread) http://forums.tccoa.com/showthread.php?t=119856.

 

I have a DOHC 4.6L (the one in the picture is a SOHC) with the same tranny and the shifter was off on mine by ~3" (had to notch the opening)

 

I also added another picture that is his final setup

Well it looks like I found an easier solution to the leaky fabricated shifter extention box...HURST 05-06-07 MUSTANG GT W TREMEC TKO SHIFTER 3915074 US $258.88

 

It says TKO but I am not sure that it won't fit the regular tremec T45, T5 or tr3650

I have decided to go with a VLSD and CV's...Which when I donate and get a PayPal account I will be putting these together. They are long nose R200 with Q45 joint on the inside and a Q45 or 300z z31 turbo joint on the outside and I make the shortened shafts. Please tell me what you think? I also included some cheezy orange and yellow photoshop pictures.

I think sir, that you have entirely too much time on your hands.

 

Here are some pictures of the Trans mount (will work for T5, T45 and TR4650) I cut the flat sections, the center bridge and the water/oil adapter. I had the trans mount welded today...I also had the 3" flat iron cut for the motor mounts, trans mount bolt bracket pieces cut and I will be welding tomorrow. See pictures.

 

PS the trans mount is upside down compared to the Ford Mustang setup. It'll support dual exhaust!

OOOPS I didn't flip the part in the middle were the mount bolts to. Well I will have to cut up another trans crossmember and do it again. I'll post pictures later.

I've still got my stock mustang trans xmember, let me know if you need it.

 

Thanks for the offer but I have a couple more...Also I don't know if I should post the brakes, suspension and more. Well here are some pictures...The brakes are my old setup that I never got to test I have moved to the Z32's on the fronts and vented rears.
