24v inlet manifold onto 12v

[HAMMER_VR6 0]

24v vr6s have plastic inlet manifolds with a VSR system built into them as standard.

My question. Can they be adapted to fit the 12v engine, the fact its plastic should help to resist heat soak, and the VSR should improve torque much like a schrick. But without costing ££££

No, but the American MK4 12v manifold fits right on, and does the same job as the Schrick manifold.

OK would there be any advantage to fitting one of these?

Dont the american manifolds have the air intake on the left side of the engine bay. (AS YOU LOOK AT THE MOTOR)

[FishWick 21]

Yep, correct. They also have an electronic throttle and a different rocker cover.

To run that manifold you would need the rocker cover, the intake itself, the PCV pipework and fittings, associated plastics and an adapter for the throttle. Although if you're OBD2, your throttle might fit straight on.

Pics of the manifold etc here - http://www.gruvenparts.com/website/diys/Performing%20Compression%20Test%20on%20VR6.htm

On top of that, you will also need to remap the ECU to account for the significant torque gain in the lower rpms. The timing will need to be pulled and fuel added where the intake tuning is strongest.

By the time you've sourced and imported all those parts, you might be better off finding a s/hand schrick from the UK.

Your a knowledgeable chap,

Sounds like alot of work and expense, for not alot of gain.

Could a 24v inlet be made to fit to your knowledge???????

Well Nigel cant take my car in until after Christmas lad he must be a busy character but hey its booked in now anyway.

It's not as much work as it sounds but it's getting hold of all the bits that's tricky!

If you could get a flange made to convert the 24v's square ports to 12v ports and stud pattern, then yeah it should go on. Thinking about how much wider the 24v head is, a 2" thick adapter might bring it right. I'll have to look at in more detail. Got a 24v engine in the garage. One thing though, the intake would have to come off each time you check / change the plugs!

I guess if it was simple everyone would be doing it

I just rang him on the blower he said he has 3 restoration projects in. Don't worry about the finish fella I am not the sort that would expect you to feel bad
