i have a growing pile of prototypes trying to make a ppf to tranny mount.

for all yous who have been waiting for opp to point and laugh... your day has come

 

with some luck, this is mount N-1. couple of small changes and should be good to go for track season this year. I still have the transmission tunnel brace but I may get rid of that all together if the tranny <-> ppf adapter proves strong enough.

This means the swap would just consist of driveshaft, ppf adapter, motor mounts, and oil pan (turbo plumbing and exhaust notwithstanding)

I still need a measurement of ppf <-> gas tank gap from a stock NA. please somebody help me out.

 

a few in-progress pics








and a vvl head i picked up

 

Let's hear more about this NA dyno chart

 

Oh ----. I thought the same thing. That ---- is funny!

 

why is it that that the front drive guys get good parts cheap? its not fair.

the head pictured above is from a fwd sr20ve motor which nissan used starting in the late 90's ('97 iirc) to be competitive to honda b series. both companies produced a crapload of civics/sentras/etc so if you can pull parts from these, you are in a good place. going rate for imported sr20ve motors minus gearbox seems to be in the $700-800 range. i picked up just the head for $400.

nissan did introduce one evolution (p12 head) with thinner valve stems etc to try to keep up, but then honda ran away again with the k series.

if you look on the right side of the head, you will notice 2 selenoids. one actuates intake cam, the other exhaust. with some mods (oil supply) fwd head fits on a rwd sr20 block - and with some luck will become next years motor.

with stock cams i see a dyno for 183whp: The Most Powerful Engines Thread. (Dyno Thread for Powerful Cars and Tuners) - Page 4 - SR20 Community Forum - The Dash

the "N1" is the hot cam for NA applications and gives the dyno i posted in the engine swap thread: The Most Powerful Engines Thread. (Dyno Thread for Powerful Cars and Tuners) - Page 3 - SR20 Community Forum - The Dash

i am quite interested in what this 212whp head brings to the table when you strap a 3071gtx to it. i went and bought upgraded cams also, but i went with the p12 cams because they are more turbo friendly than the N1's. unfortunately, like the N1's, they cost around $400.



anyway, the point of this is, there are a number of interesting possibilities and things to try with a motor with one foot in the fwd world and one foot in the rwd world.

 

Jasoooooon!
