Has Anyone (Hot Rodded) a 2.7
 

I 'am curious, If I ever had to rebuild my 2.7..could you rebuild it for more power or torque using different cam's and head work Etc,like you can on most engine's ?? Thanks Frank

I can't think of anyone that has tried. As a goof I stuck a 3.4 intake and throttle body, along with a 3.8 exhaust manifold on my 2.7 rallycross boxster. I haven't gotten it on a dyno but I can tell I lost some low end torque and think I gained HP above 4500rpm. Those 2.5/2.7 heads can't flow much. I don't think you can run 3.2/3.4 heads on a 2.7 either. You'll have better luck for cheaper upgrading to a 3.2 or 3.4

There's some interesting interchangeability mentioned by Jake Raby here: https://rennlist.com/forums/996-forum/684465-is-there-a-diference-between-a-3-2-986-and-3-4-996-head.html#post9339329

Cams & head work ? Do what Porsche did increase displacement!

Sure you can. New pistons, rods, bearings, cylinder liners, etc. Lots cheaper to swap a 3.4 from the same year into it though.

Yea..if I ever had to I would go the 3.4 route I was just curious because my Cam deviation numbers are not great..Bank 1 = 8.6 and bank 2 = 3.6 or something ,..I will do tensioners and see if those numbers change but I doubt it

BYProdriver,..back with the 1979-88 with the 3.0 Ltr engines you could install the 964 cam's and get a nice Bump in power..and so Iam curious if the same could be done on these engine's not really displacement just some extra kick so to speak,..But I'am sure computer controlled engine's are most likely set at there best performing range already

Isn't it the chain ramps worn out and needed to to be changed if the deviation is getting high?

That's before Porsche was on such a tight budget & had been improving the same engine for 20 years. Installing a "bigger" cam increases high rpm power with a notable loss of low rpm torque which is what gets the car moving. Engine displacement size is the main factor that determines low rpm power to get you moving. Thus the phrase "there is no replacement for displacement!"

Pilot4fun..IDK,..I thought it was the actuators and BYProdriver Ahh ok,I like the low end grunt,.dont want to lose that..! Thanks ! frank
