Hot Cam for Corolla 1.8

Sideways · 8th July 2007, 02:15

No point installing high lift cams without increasing the compression. Apexi SAFC Neo will also help to control idling issues.

the cams would run on the stock ecu ?
@sideways new pistons and rods are needed for upping the compression right?
with my current compression should i expect a 10 hp gain?

will i loose on low end torque?

Only piston needs to be changed to go higher compression, you can even shave the head to get slight increase in compression, btw whats stock c.r of corolla engine?

paras211 · 8th July 2007, 12:40

i dont intend to up the compression its 10:1 will the cams be useless at this compression? if i get 10 wheel hp i ll be happy

What cams are those ? are they "bolt on" or "regrind"? If getting bolt on make sure its for the same engine which you have here,there must be various variants for corolla engine abroad, pls reconfirm it before buying. also whats the duration & Lift of your stock Cams?

paras211 · 8th July 2007, 16:48

yea they bolt ons for my engine
Stage 1: 264/264 duration, .379/.367" Lift
Stage 2: 272/272 duration, .396/.396" Lift
still ecu will the stock one do?

Stock ecu should work, but i would like to compare the specs of your new Cam with the OEM in terms of lift & duration, the specs you posted i think are of aftermarket cams. whats the spec of OEM CAM ? dur/lift?

paras211 · 8th July 2007, 17:09

where can i find those specs?

paras211 · 8th July 2007, 17:25

are these the specs?
Celica Engine Timing and Lift Characteristics

Variable system VVT-i
VVT-i and VVT-L

1ZZ-FE
2ZZ-GE
Intake valve opening
5-48° BTDC

Intake valve closing
55-12° ABDC
Exhaust valve opening
42° BBDC
Exhaust valve closing

No man, that's a screamer. It's the 1.8 on the Celica NA and the Corolla sport or whatever. I think the Solara or something too, which a BHPian has. Puts out like 170 hp.

paras211 · 8th July 2007, 20:12

i know baba the specs i ve put are for the 1zzfe the celica is the 2zzge which is a direct fit .you know of any 2zzfe engines lying around?
the 2zzge is also used in the lotus

v1p3r · 8th July 2007, 20:14

There aren't any lying around, to the best of my knowledge. Can import them though.

paras211 · 8th July 2007, 20:22

wont be able to afford one now i ll have to get a 6 speed to use the full potential . should i get one for bout 2 lac?

v1p3r · 8th July 2007, 20:54

Why waste all that money? Just turbo your car. Corollas seem to respond well to forced induction. The catch will be finding someone who can do it.

KSMOTORSPORTS are very good in TCing i have heard.
