mantaboy89 Posted January 8, 2010 Share Posted January 8, 2010 (edited) Does anyone know what needs to be changed altogether to fit the injection system onto an older cih engine if it was running a carb. does the head have to be changed etc,, also does anyone have a 2.0ltr for sale? also does anyone know what amp fuses go where in the fuse bord? Sounds like a funny question but when i renewed the fuses i replaced them for what was in there previously but i doubt these were correct due to the previous owner not having a clue and the fuse bord is in german.lol Thanks Josh Edited January 8, 2010 by mantaboy89 Quote Link to comment Share on other sites More sharing options...
Snowy Posted January 8, 2010 Share Posted January 8, 2010 You can fit the fuel injection to your engine as it is. People will tell you that you need to change the cam but i've done several 2.0S engines and the have ran fine. look here... My 4 door cav Any questions just PM me. I have done this conversion a few times now. Quote Link to comment Share on other sites More sharing options...

However, in brief the following: Injection fuel tank (or add return to existing) Fuel lines Injection pump and filter assempbly Plenum chamber with throttle body and injectors attached. Thermostat housing Air flow meter ECU Wiring loom (injection loom has four wires that splice into car loom or add connector and a ring terminal to started motor are, plus will need to run a fused wire from this to pump at rear) Injection relay Be prepared to drill various holes in body for pipes and wiring. Standard dizzy probably suits cam profile better than the electronic one, but there is no need to fit electronic dizzy to run injection Sorry wrote too much I'm generally in favour of search beong used before providing info.

MANTAMAN Posted January 8, 2010 Share Posted January 8, 2010 the above post by Mantadoc covers it, but i have questions, The outlet pipe on a fuel injection take is a larger diameter presumably so as the pump can convert volume to pressure,so can you run injection off a carb fuel tank? The injection dizzy has wiring to provide a signal for the rev counter/injection ECU,can the wire to the points dizzy provide this signal? Has the points dizzy avance curve near enough to work properly with injection? or are they even the same? One thing you have to do is make a blanking plate to replace the mechanical fuel pump. I have one Manta lined up myself for this conversion so i have given this subject some thought but still not sure on some aspect. Quote Link to comment Share on other sites More sharing options...

High volume low pressure to lower volume high pressure. You could fit lift pumps and some people will tell you you can run the return line to the lift tank (or swirl pot if fancy)to reduce the quantity provided by from the lift pumps. Of course the lift tank really should have an over flow / return to the tank anyway as the lift pump setup shold be designed to lift more than the injection pump can eat. Plus, of course, no self respecting tuner or skyline fan wolf recirculate the return line as the fuel picke up heat on travel around the engine bay and back which is exacerbated by compressing it. Hotter fuel, less dense charge, less power ok? The injection dizzy has wiring to provide a signal for the rev counter/injection ECU,can the wire to the points dizzy provide this signal? Has the points dizzy avance curve near enough to work properly with injection? or are they even the same? The trigger runs off the rev counter wire. If you have a rev counter, you have the wire. One thing you have to do is make a blanking plate to replace the mechanical fuel pump. Or leave if free wjeeling with the pump in place. Draw around a gasket for the plate although any relatively flat piece or say 2mm or 3mm steel will do. These [plates can also be found on a fair few cars that were available as injection or carb models on the same block. Quote Link to comment Share on other sites More sharing options...
spiney_norman Posted January 8, 2010 Share Posted January 8, 2010 I'm pretty sure it's not a conversion from a carbed B to an injection engine Josh is after, but putting a 20S engine into his existing GTE which has a knackered bottom end!

mantadoc Posted January 8, 2010 Share Posted January 8, 2010 Good point, but it was an ambiguous question , although I remember he is looking for an engine now you mention it. Quote Link to comment Share on other sites More sharing options...
Snowy Posted January 9, 2010 Share Posted January 9, 2010 Like i said, my post pretty much explained all of the above. I HAVE done this several times. So if you need any info drop me a PM. Thanks Quote Link to comment Share on other sites More sharing options...
mantaboy89 Posted January 9, 2010 Author Share Posted January 9, 2010 Thanks for all the info posted by the members. This should help with finding an engine to fit in my car. josh anyone got a fuse board diagram? Quote Link to comment Share on other sites More sharing options...
mantadoc Posted January 9, 2010 Share Posted January 9, 2010 There's various fuse layouts depending on model and loom. It's also on the back of teh fuse box door, if you want to www.freetranslation.com a little german. If you haven't got one already, Get a Haynes manual off ebay, cheap as chips, defninitely cheap enough to get oily. Quote Link to comment Share on other sites More sharing options...
