chris_bramley Posted February 21, 2006 Share Posted February 21, 2006 The Engine is rebuilt! And it's been a long time coming. As usual, the simplest thing that was removed first is the only one we can't work out where to re plug it - anyone with experience of mods and EVC, please help! from the EVC system in the bay there are 3 hoses, one of which leads back into the car to a boost gauge, which splits off in a T and also connects to the throttle body. The next one come up to another T, one of which connects to the intercooler pipe on the turbos and the other is the mystery long vacuum hose which from the length and vague memory goes across the engine again to the throttle body side... but I can't find ANYWHERE it goes! from the length (1 meter or just over) it goes over the engine, and from an old pic is seems to sit down near the BOV T connection, but all of those have pipes!! So I'm a bit stumped . The last plugs into a T on the second, so the whole system is like this: *crap image deleted* Hope this makes some sense, it's from memory! anyone who can help pleeeeeease do I haven't driven this car for over 5 months now and if I don't get it fixed asap I might just go EDITED: Looks liek this diagram is wrong, wrong, wrong! argh.

chris_bramley Posted February 21, 2006 Author Share Posted February 21, 2006 hpoe this helps:) http://www.hksusa.com/faq/?ID=1647 Thanks dude, unfortunately I've checked all of those... and bizarrely they don't have one for the V! the diags they have are basic anyway. I mean, I AM presupposing that it was done correctly on the car in the first place before I got it... it seemed to work when I was driving it! Maybe I should start again :s Link to comment Share on other sites More sharing options...
Chiefgroover Posted February 21, 2006 Share Posted February 21, 2006 It goes to the balancer box. If you look at the bulkhead side of the turbos there are two metal pipes going across the rear of the head just about the top of the bell housing. Its one of those. If you cant find it you can also run a hose across and straight onto the balcer box which is directly below the intake manifold near the starter, most likely get at it best from below. They are right beside the rear rhs corner of the head. Link to comment Share on other sites More sharing options...

chris_bramley Posted February 21, 2006 Author Share Posted February 21, 2006 am I right in thinking that even with uprated twin turbos, it's still an internal actuator? Or am I looking at another setup? Link to comment Share on other sites More sharing options...
chris_bramley Posted February 21, 2006 Author Share Posted February 21, 2006 Right, here's the thing. the car starts (hurrah!) But runs a touch lumpy at the moment and is not bringing in the first turbo - it just kind of chokes and not much happens. Obviously she's just been rebuilt up from block so there are bound to be a few teethings... I am convinced I have that hosing wrong (see diagram)... does anyone kindly have an evc installed that I can BEG them to run and take pictures of so I can get my twin turbo thing to respond as she should? I just don't know enough about the assembly to interpet the HKS "manual". I would be forever grateful, car seems to be running pretty rich too. I might post a seperate topic on tuning the thing now it's actually alive again! Thanks for all the help guys Link to comment Share on other sites More sharing options...
Supraman Posted February 21, 2006 Share Posted February 21, 2006 I've got an EVC V installed. I'll try and take some pics tomorrow of the set-up and email u pics. Unfortunately I only have the camera on the mobile to hand, but hopefully it will be good enough. Link to comment Share on other sites More sharing options...

I'm in finger's breadths of being back on the road after 5 months and I'm chewing up the walls at the thought of being seperated from it all still you can chuck them at [email protected] if you like, hopefully I'll be able to solve this mystery pipe thing...

Chiefgroover Posted February 22, 2006 Share Posted February 22, 2006 DUMMYS guide to fitting an EVC 5 One large vacuum pipe goes to the Y piece, you have that sorted already. Block off the other end that used to go onto it. The other large vacuum pipe goes to the balancer box. the send and return lines are at the back rhs (yeah closest to the driver) corner of the cylinder head. The two pipe ends that are visible will be vertical before becoming rubber. Take off one of these and put your second pipe on here. They are a little difficult to get at. Your two large vacuum pipes are now correctly installed. Easy, so so easy. Just be sure you block off any pipes you take off. Link to comment Share on other sites More sharing options...

Hmm see when I looked the balancer box already has 2 hoses on it (if I found the right bit), and the EVC was hooked up differently... which either means I'm misunderstanding what you're telling me, or the guy who had the car before me had it done wrong. I think this is why I need pictures of each bit and each connection so I can copy it exactly, I still don't know which bit is called whi enough to do this off the top of my head from text!

chris_bramley Posted February 22, 2006 Author Share Posted February 22, 2006 Pictures winging their way via email! Hope it helps thanks mate, just had a look... I think that will def help! tho you seem to have a different setup to the way mine was done with the red hose etc, most of mine are still in the same place, it's a good reference. I think I need to see the throttle side as well :s I just took pics so I can post them here and see if you guys can come up with any suggestions, I'll drop them in a new post in a sec. I'm still not sure where the ones plug in on the throttle side - one is a feed to port 1 on the evc, one feeds from the balancer box to the line that connects port 2 to the wastegate under the first turbo, and the other feeds to the intercooler pipe. The third one is the mystery for me, I can't work out why there would be ANOTHER T piece for a hose that goes across the car! Post with pics to follow...

chris_bramley Posted February 22, 2006 Author Share Posted February 22, 2006 Right, here are 4 pictures to show the current setup. http://tinyurl.com/qusko ftp://[email protected]/evc1.jpg This one shows the EVC. The left hose is port 1 going to the green clip and T junction, one of which goes to feed the boost gauge in the car, and the other of whic goes across to the top hose on the T in the middle of this second picture: http://tinyurl.com/q686z ftp://[email protected]/evc4.jpg which takes care of port 1. from the first pic you can see ports 2 and 3 going off to the right, shown in more detail here: http://tinyurl.com/l7f9c ftp://[email protected]/evc2.jpg the hose from port 2 connects behind the others onto the intercooler pipe above the first turbo. Notice halfway along it there is a T bar with a smaller hose - this one is the 3' hose which I have NO idea where the other end goes, all I know from vague memory is somewhere over the other side of the engine bay around the ECTS (lack of free pipes means I'm stumped with this). the lower pipe, from port 3, connects onto the metal pipe that leads to the balancer box, and the other part of the T goes down under the intercooler pipe to the end of the wastegate actuator thing, shown from the front here: http://tinyurl.com/mkyps ftp://[email protected]/evc3.jpg So, does this help anyone know what I'm meant to do? far as I can tell they're all in the right place, but my first turbo isn't spinning up and unless the loose pipe goes to the BOV (which has a T bar that connects to the throttle body but all pipes are on that too) then I have NO CLUE where it was meant to go. Have I got any of these hoses in the wrong place? Tell me if I'm being a plum! She's running lumpy at the moment and when revved the first turbo doesn't come in at ALL, no spin noise, just a kinda of anticipatory silence. I MUST be missing something, the turbos worked fine last time she was on the road. Any help would be shiny! *EDIT: picture locations added under pictures* Link to comment Share on other sites More sharing options...

chris_bramley Posted February 22, 2006 Author Share Posted February 22, 2006 Not seeing any pics mate Odd... they show up in mozilla! I've edited the page with the ftp locations in case the images aren't showing Additional info: I remembered one of the balance box hoses was actually blocked off befire it went into the balance box, and I found a little blue valve thing under the dagnosis box that looked like it might need a hose. tried every possible way of attaching that long hose to it, blocking the top and bottom balance box hoses, also tried putting the long hose in one then tother balance box pipe. i seem to remember one of them (bottom one?) having an open pipe and being blocked off with a screw at the hose just before the box, and the long mystery hose going somewhere over the throttle control and down but who knows where (mystery blue thing closest match so far). just disheartening that no matter what I do it runs the same car still runs badly, it's idling a touch faster than normal (1k) but sounds fine, till you squeeze the throttle, and then it gets juddery and lumpy, and then the turbo doesn't kick in and the engine almost catches it's breath - compressino feedback or something? Smells like it's running rich too - everything LOOKS right now but I'm guessing it's still a major vacuum issue causing all this... Running out of ideas pretty fast at this point, hope someone can check the pics above and descriptions on this page and shed some light!

Supraman Posted February 23, 2006 Share Posted February 23, 2006 OK had a look at your pics and can see where the EVC is positioned. Mine is positioned on the other side of the engine bay. In the pics I sent you 40 has my finger pointing to the hose which comes across from EVC. I'll take more pics from around the EVC and post tomorrow.

chris_bramley Posted February 26, 2006 Author Share Posted February 26, 2006 Thanks, I think I've managed to get it puzzled out.. partially down to the pics you sent now the only thing is the fact the turbo isn't dumping. I think here the spare pipe is def meant to go to the balancer box, and then the other pipe which comes over to the metal pipes is hooked up. I wonder if it matters which pipe on the balancer box matters with which hose... but either way, I think I'm close! took her for a quick drive, not going to boot it after a) the rebuild and b) no dump valve (!) but I could feel a lot of pull so looks like compression is ok! I'm so close to driving her again, I can smell it. Link to comment Share on other sites More sharing options...
chris_bramley Posted February 27, 2006 Author Share Posted February 27, 2006 Argh! It won't be dumping cos a few months in a garage appears to have rusted my BOV shut. Damn blast and heck it all freeing it up now, if this doesn't work it's a new one. any suggestions? Bear in mind I prefer the straight "PSSH" noise to the flutter effect *Update* ok, managed to revive BOV. I'm still a little confused as to which pipe the long hose should go on on the balancer box, and which old hose (top or bottom) gets blocked off. add to this the top rad hose was getting pretty solid when the engine was hot and the fact that one of the old hoses sprung a leak, and I still have a problem. If I can get the hose order and which ones are where on the balancer box, that's that and all I need is to solve this other issue... Thanks for all the help so far guys, any more ideas on hoses etc would be shiny Link to comment Share on other sites More sharing options...
