bought these a few weeks ago for my new engine build for the xr2, finally got em so ive started getting them sorted to go on! let me know what you think
started having a play with them today, here they are as they arrived:
soon had them stripped down!
they come with electronicly controlled 'chokes' which the ecu opens by a servo depending on TPS and revs to give optimum torque. itd be an absolute bastard to map it into the megasquirt so im not bothering with it, so all thats gone! then i took the fuel rail and injectors off. ive got to space them out to get equal length inlet runners, so obviously the fuel rail is no good and is now in the bin.
ive been out today and spent a small fortune on bits and bobs to get them all uptogether. samco hoses, a huge pile of jubilee clips, fuel hose and T pieces to make the fuel rail etc etc. was gonna get some thin ally tube to use as spacers but couldnt get hold of any so ive just packed the gap with washers on a longer bolt, bit cowboy but will do the job perfect for now. gonna make up a fuel rail in a few mins, weld the linkage to reach now ive spaced them out by 35mm, plumb in the vacume hoses etc etc and will start drawing up the dimensions for the manifold later, thats gonna be the shit part :blub:
one thing im not sure on is the head side of the throttles where theyre gonna go into the manifold, not happy with the huge step up theres going to be, ive a feeling it might cause a turbulent area round the edges and fuck up the flow, gonna do a bit of research and see what other people have done. ideally id like to open it all out so its a smoother trasition but will see.....
linkage is not gonna need any messing about with, the std for cable will work on the spindle, then just needs the sheath clamping into the little eyes! can see the cold start lever on the left hand side, will run another cable to that as a choke cable for cold days, will raise the idle speed a touch!
and a random one of the TPS
cameras fucking about now so cant take any more pics, will try and get some tomorow though, hopefully by then ill have it all together and sorted!
