I'm searching an info (more specificly any problem or side effect) on putting GTi6 manifold (together with injectors and butterfly valve) on a XU10J4R engine.
I did go through the topics and FAQ, but I found only one comment that the low-rev may go crazy.
It was actually done in Thailand as well.
XU10J4R (called 406-D8 engine in Thailand) was put in 405 body, with XU10J4RS manifold, header and cams.
He got 150 hp atw.
You can see some photos here.

I did talk to the owner and he said that..
on the low-rev (or idle), sometime the rev just jump up without warning, especially if temperature in not up to operating condition yet.
So, he warned me if I want to put this manifold on my 306 cab (just put XU10J4R with AL4 in; replaced original XU10J2 with 4HP14). I might face the same problem; but it will worse because mine is auto-transmission which can't put the clutch to cut off engine if it goes crazy.
He thinks the (old) ECU can't handle the new setup in some condition, probably.
Are you facing this problem or any other side effects which I should be careful about?
Any ideas to prevent that low-rev crazy?
