Looking for MTM Intake Manifold Pics

[mcandmar]

Another thing I had to do was file of a corner of the hydraulic pump bracket, to give about an extra 10mm of belt adjustment.

Is that a 3B pump bracket? You also seem to have a lot more clearance between the tensioner bracket and manifold. I wonder if a 3B uses a shorter belt and mounts the pump lower down

Yes. It's a 3B bracket.

How did you get on with this, Mark?

I have plenty of room above the alternator for the ISV. But I would still be interested to know what MTM did.

Hey Stu,

The way i got around it was with three 90 degree samco hoses, basically routed the pipework from the intake hose down under the intake pipe to the front side and into the ISV. It seemed the easiest solution as the wagner IC hose and MTM manifold ISV connections were on the opposite sides. Hard to explain really so i will try and snap a pic or two from the owner.

As for the alternator a 900mm belt did the trick, and just cleared the intake manifold. 920mm was too big so as close to 900 as you can get is ideal. That was for an ABY ribbed pulley so not sure about 3B as the pulleys are different sizes.

Cheers,

Mark

Thanks Mark. That has given me an idea.

Using a 90° bend to get from the inlet on the manifold, back under the throttle body to the ISV seems like a good idea. I think it will look a lot neater with the ISV hidden behind the TB.
Finding somewhere to hang the ISV from isn't obvious at the moment. But I am thinking about making a spacer to go between the TB and the manifold. I am still not happy with the clearance between the throttle cam and the underside of the bonnet. I could make it so that I have a point to hang the ISV on.

The only thing that bugs me is why didn't MTM move the TB mount further down in the first place?

Funny you should mention it i discovered when attempting the first test drive i couldn't move the throttle pedal as it was stuck against the bonnet

As you say if only the throttle body was further down it would have cleared fine, but instead we had to remove the plastic trim from the underside of the bonnet.

From memory i opted to place the ISV on the front side due to clearance issues with the AC radiator, there was just enough room to route the plumbing on that side into the wagner intake hose. ISV is basically self supporting but with more time i would have liked to use the original rubber mount for it supported off one of the throttle body bolts, a spacer dosent sound like a bad idea at all as it would resolve both issues.

Also check the plastic injector mounts in the manifold, with this one they were really lose in the threads and leaked. Were unsure if it was a genuine MTM manifold or a copy as it also required a bit of a massage to fit around the water manifold on the head. Really wasn't impressed with it at all.

I thought there was enough room underneath the TB, but I will try the AC condenser in place to make sure, rather than just by measuring.

I think I remember the plastic injector sleeves nut being tight. The casting on the manifold was a little rough in places, but I think it fit ok.

I think Tom had trouble with a leak, at the join on the ISV bend.
IIRC Bo had trouble with bolt threads leaking. There are always sneaky little things that catch you out on a mapping session.

Thanks for making me Check, Mark. I didn't realise the condenser was spaced off of the radiator so much. So there is my clearance on the ISV gone. I think there is just enough room underneath the TPS. With the orientation of the ISV connector, inlet and outlet, it doesn't lend itself to tight spaces.
