yeti132 Posted June 25, 2017 Share Posted June 25, 2017 Can anyone give me advice does 2.2 inlet fit a 2.4 frontera because I no the 2.4 inlet sits to high to shut the bonnet Quote Link to comment Share on other sites More sharing options...
mantadoc Posted June 25, 2017 Share Posted June 25, 2017 It does because the 2.4 Frontera lump I bought in 1999 has one I put on it, on it for the last 18 years. One day I'll use the engine Quote Link to comment Share on other sites More sharing options...
nickincrete Posted June 26, 2017 Share Posted June 26, 2017 yes but it ,2.2, actually has very narrow castings. smaller than every fi manifold fitted to an opel, the 2.0 one is better and can be made to fit, for my opel gt i have used a 3.0 6 cylinder manifold cut down and welded and this gives the highest flow.

Which is ok depending on what injection you are using, and throttle and airflow meter, and if tuned appropriately If the narrow runners can feed the 2.2 which IIRC has bigger valves then it may be a better design, depends on the CFM it can shift and if matched to the head. Additionally if narrower runners can supply the CFM, then they are adequate and come with the benefit of higher airspeed at low RPM which gives better torque and pickup Quote Link to comment Share on other sites More sharing options...
lamchop77 Posted June 27, 2017 Share Posted June 27, 2017 It does but i would use a modded 2.0 unit. Guy i used to know use a 2.2 with injection for oval racing. He had his own rolling road so could play around with settings/etc. He reckoned using the 2.0 injection bit gained about 7 bhp over the 2.2 setup. You have to remember the 2.2 was setup as an economy engine, not a power motor! HTH Chris 1 Quote Link to comment Share on other sites More sharing options...
mantadoc Posted June 27, 2017 Share Posted June 27, 2017 With 2.2 hard to get and 2.0 as common as door stops these days the 2.0 looks more convenient for just drilling the dowel holes Quote Link to comment Share on other sites More sharing options...
lamchop77 Posted June 27, 2017 Share Posted June 27, 2017 Agree Mantadoc, plus the 2.0 is a much simpler system and you can use a 2.0 modded distributor if you want a decent cam in. Std 2.2 dizzy has no advance/retard inside, it was all done electronically via a little black box! Quote Link to comment Share on other sites More sharing options...
mantadoc Posted June 27, 2017 Share Posted June 27, 2017 My intention was use the Motronic 1.5, way better than the analogue clockwork Jetronic Quote Link to comment Share on other sites More sharing options...
