2.4 Inlet General 2.4 Inlet Manifold Questions

the 100 Amp alternator is too big and when modded has about 1 or 2mm clearance :?

the extra 5mm means it's a no go :(

even with replacing the alternator it's still a cheap 20 bhp, just not as cheap as if a 100 Amp was fitted originally :roll:

Suddenly homosexuality seems that little bit too tempting...

Erm, I mean, cars, women, guns etc

Rik over on VX forum (and possibly on here) is hopefully getting me a 100amp alternator from his local breakers. Fingers crossed theres enough for him and me!

you just need to learn to "not tell the wife" :LOL:

deny the cost, deny buying it, insist it was broke and requires replacing, claim it was in the boot when I bought the car.....the list is endless :LOL:

120 Alternator

acdn.z22se.com_userpix_1076_alternator_1.jpg

It appears i have a 120A alternator :cry: I managed to get a digital camera into the bay so at least I know for sure.

Slimvince back in the thread posted a link to a modified 2.4l manifold:
http://www.vx220.org.uk/forums/index.ph ... 5747&st=40
But as it is swedish I dont have a clue what it said, however it looks like modding the manifold is possible. Can anyone shed any light on what was done here?

TIA

Short version: On OC_Peter's Speedster he had the 120A alternator and in order to make the 2.4 manifold fit he first shortened one of the bolts on the alternator by 1 cm, but the mani still did not fit (another 15mm was needed) so he had to modify the manifold too.
Some of the pictures show that it is the circular protruding part on the mani that still hits the alternator that is shortened. This protrudes the 15mm that is needed. I believe oc_peter sawed it off and then glued back the sawn-off part as a lid.

He also writes that the hole that gets made is not as large diameter as the part he sawed off. By sawing it off a hole quite a bit smaller in diameter gets created.

OC_peter modified both alternator bolt AND manifold, I'd guess you'll have to do both, otherwise one would have removed too much from the manifold.

And - yes - he is happy with the end result!

Haven't done this myself since I have the 100A alternator.

Thanks slimvince!

Couple more questions which bolt on the alternator was shortened and was this done with the alternator still in place?

What does the lump that was cut off do?

TIA

He wrote that it was the "12 V" bolt he shortened, and I would interpret that as the one to which the 12 V feed is connected (not the one that the suppressor is connected to). This bolt (on the 100A alternator at least) is the one that protrudes the most and only has a mm or two clearance to the manifold.

It could probably be done with the alternator in place, you would have to fasten the bolt first using its nut (and also when undoing the nut again the threads on the bolt that were distorted by sawing the bolt off will hopefully be fixed again when undoing the nut (if you don't have a thread tool). It certainly would have been possible to do this on my speedster - but I have taken the rear clam off to have better access to everything - yes I am cheating. It's a matter of being able to get a saw/dremel in there or not.

I don't know what the two things on the manifold ends are...maybe some holes where the casting was removed from inside the mani and then covered by lids that were glued in place?

1. What's the purpose of being able to remove the part indicated with a red arrow?
2. One grounding lug I remembered to fit to the ECU, but the second lug - where should it go (green arrows)?

1 = ease of manufacturing, it could be glued in place dunno..

2 = the ecu, you have a similar loom as Luna_s notsure.gif

If some photos with arrows and stuff could be put up for the mods to the manifold and alternator for those of us with 120amp alternators I would really appreciate it!

Vocky, TIA :razz: cheers..

walkthedog.. <-- love this smiley for some reason

the guy who has modded the alternator is OC Peter on the swedish bit of the vx220 forum. Slimvince has been very helpful and may be able to get something from OC Peter cheers..

I think modifying the 2.4 inlet manifold will be far easier and cheaper dunno..

I must admit I came within a few seconds of cutting the plug off mine :eek:

I chickened out and modified the 100 Amp alternator :LOL:
 
Is what Muncher83 said on page previous about the 100A having a black plastic pulley and so on gospel? I have one with the metal pulley and Im thinking (but cant see to clarify) its a 120A :(
