ok here's the deal, right now i own a 240sx...so i don't know all that much about the 200, however my girlfriend and i (who's sn i'm using) acquired one for free...it's and '85 with the CA18et, i noticed that the charge pipe from the turbo is run directly over the valve cover and thought that was kinda ineffcient but i see no way to relocate the throttle body to support an intercooler and such without runnning the pipe back over the motor, thus negating the use of the intercooler...has anyone done this or am i talking about A LOT of custom work?

Some people have put CA20 manifolds on their cars but it's a decent amount of work from what i hear. It actually isn't that bad. Most of the people with turbos just run the pipes where you need them with the stock manifold (which I actually like).

eh...i just don't like the idea of the charge pipe being near the valve cover and being exposed to that much heat....what are ya gonna do?

i'll see if i can't get my hands on a Ca20 mani (there's a couple in junkyards around here) and go from there...if it looks too difficult i'll throw in the intercooler my gf buys and make some custom pipes to fit...

It's actually very efficient. The air is being drawn into the intake manifold from the most central point, resulting in near identical air flow to each cylinder. The air flow is also in one constant direction so no loss in air velocity is noticed. The heat seen radiating from the engine into the pipe by going over the valve cover in minimal at best.

Take a look at the R33 Skyline's RB25DET. Nissan used the 'over the top' pipe design until 1997 and in one of their most expensive cars nonetheless. It was done like that for a reason.

The only real downside of the design is that it makes the engine bay look ugly. :p Meh.

i guess i could vent the hood cowl and bring some extra air in that way...keep the heat away... :laugh:

just put a large heat shield under the ic piping and that will keep alot of the heat off the pipes

lol

i always forget the heat sheild option....

Use a heat shield and get the pipes ceramic coated inside and out....this will also help with heat.......or wrap the pipe with some of that exhaust wrap stuff.

ah yes even better idea.. ceramic coating can reduce engine bay temps in the degree of 30-100degrees..
