so i've mentioned here and there about my brother's SR powered sentra. i just figured i'd finally shed some more spot light on it.

year:
1991
make:
nissan
model:
sentra SE
engine:
SR20VE(neo VVL, its a variable valve lift and timing version of a regular sr20)
86mm bore x 86mm stroke
10.3:1 compression(stock)
1998cc
oem cam specs
Intake cam
Low lobe: 8.4mm lift @ 220 duration
Low lobe center angle: 110deg
High lobe:10.7mm lift @ 264 duration
High lobe center angle: 104deg
Exhaust cam
Low lobe: 6.6 mm lift @ 244 duration
Low lobe center angle: 122deg
High lobe:10.34 mm lift @ 268 duration
High lobe center angle: 114 deg
mods:
custom 3" SRI
BPi velocity stack
megan racing 4-2-1 header (absolute junk on these. it only has a 48mm collector)
exhaust shop special crush bend 2.5" exhaust (crap)
nismotronics with base tune for VE
trans:
stock b13 SR20DE trans
old setup:
SR20DE
different Intake same Header/Exhaust with JWT S3 cams
out with the old
altering an obd2 b14 ser wiring harness for use on the sr20ve
engine goes in from the bottom. its actually less than a 1.5hr swap once the harness was on the engine.
in with the new
dyno results
after this session we found out that the base timing was off by about 7 degrees. just for reference on the SR20DE 5 degrees timing advance is about 6-8whp. but for now future plans are for SR16VE N1 cams, intake manifold with the oem 70mm TB and one of these headers
with a 3" mandrel bent exhaust and a real tune. it should be a solid 230-240whp. oh did i mention this thing is 2400lbs with full interior+driver and fuel. needless to say if it ever hooks up, it'll be a monster. all it does now is spins 1st-3rd, lol.
