Guest Anonymous Posted July 16, 2002 Share Posted July 16, 2002 I have a stock 78 Z. I was looking at boring out to a 60mm throttle body with the lathe and laser at work. I would like to make around 225-250hp. Maybe not the smartest thing but I would like to see it do the 160 on the speedo.I thought about 75-76 intake(no egr) and sending it to extrudehone. I have never worked with them or heard of an aftermarket intake. Headers,cams,valves,etc.- I'm starting out slow so any specfic advice is more than welcome.

z-ya Posted August 19, 2002 Share Posted August 19, 2002 Just buy a 240SX TB from a junkyard. It will bolt u to the stock manifold. You will need to port match it to the manifold though. If you want to use the stock throttle linkage, you need to make 1" spacer too. Pete Quote Link to comment Share on other sites More sharing options...
Lockjaw Posted August 19, 2002 Share Posted August 19, 2002 I have not heard of anyone sending an intake off to extrude hone, so I can't say good or bad. I would think it would be pricey for the HP gain, but that is just my opinion. The 240SX tb is a good cheap mod. You should be able to get a machine shop to fab up a 1 inch spacer out of aluminum if you give him a gasket or the TB to use for a template. I think I paid 25 bucks or something like that.
