t25 for a project car

[Hitmachine101]

got a question about the t25 in general, im thinking about making a rear turbo system for a 89 honda prelude 4ws just to say that ive been there and done that

the car is gutless and an extra 40hsp will help it actually move in 3rd and 4th gears

so my question is does the orientation of the turbo matter for the oil feed and oil return lines?? the way the turbo sits in the dsms is with the return line right above the oil pan

im worried that if its on its side or just has a long line to get back to the oil pan, that the back pressure will hurt the seal in it

again im looking to make a rear system turbo to keep the engine temperatures down and eliminate the need for a intercooler because honestly i dont have any freaking room in that car with bumper orientation to slap an intercooler in there

thanks guys for the help

most rear mount turbo kits have a oil pump to pump the return oil back to the engine. on my friends trans am with the squires kit it ran to a special oil cap so you did not have to tap the pan.

ok didnt know about the oil pump, ill look into that, how did he set up the intake for the turbo,, did he route it through the trunk? im worried about water sucking up in this thing on a rainy day
