Hey guys,
Ive got an 88 st165 celica, which ive replaced the turbo and exhaust with an st185 twin entry ct-26, with 3inch down pipe. Also using 10pound 38mm external wastegate.
Front mount air to air intercooler with bov up by throttlebody, with the topmount water to air and pump all removed.
Got quite a few issues of where to run everything to, any help would be much appreciated.
Right so im pretty sure before the turbo swap, the water pipe by the radiator cap, ran into the turbo housing, then from another pipe off the housing into the waterpipes runing behind the rockercover. now that ive got the 185 turbo and have removed the water to air intercooler, do i need to blank those two jackets in the housing off, and then just run a hose straight from the radiator water pipe, to the pipes behind the rockercover? If not could someone please tell me whats needed to be done.
Secondly, on the turbo itself its got a small vacuum line for the pressure signal, do i run that to the bottom banjo on my external, or somewhere, or blank that off?
Thirdly, i need to connect up a boost gauge, and also a manual boost controller, and would like to remove the t-vsv. where would i run the boost gauge, boost controller to and from? also do i need to run hoses from the bov or top banjo of my external to anywhere, or just leave them to atmosphere?
Anyhelp would be good and if you need any more info, id be happy to provide.
I am just in an apprenticeship as automotive technician, but unfortunately, when bought the gt4, most of it was disconnected. once i can get all my hoses sorted, and all my plugs that seem to be leading to nowhere, with no other plug to connect to, figured out, i will then be replacing all fluids, plugs leads etc as with the pipework its gonna be a b*** to carry out maintence once its all together, so might aswell do most/all of it now, then just take apart when needing repairs.
I will upload pictures of all areas im referring to, also if i need, ive got the water pipes entering and exiting the turbo housing if I need to refit them. and alot of other spares, including st165 ct-26 and 3 st185 ct-26 and all factory wastegate actuators etc.
Thanks again.
