Well, I reckon youve answered your own question.
Youve tackled a job of this magnitude and complexity and you DONT have a 10 dollar timing light to check things out???????
What would happen if you got the timing too far the "other" way and its detonated itself to death???
All that work, for nothing.. possibly.
This goes for all, not just you dude but it might pay handsomely to have the appropriate tools and equipment at hand BEFORE tackling the big jobs.

You can hear pinging quite easily, But if you don't know what pinging is then your simply fucked!..On the other note, Cars that run coil packs & no dizzy, You can't check the timing unless you have a computer hooked upto it, So basically what I did what my r32, 180, s13 etc was to advance the timing bit by bit until I heard pinging, Then backed it off the slightest

lol dont do that, thats friggin stupid, i have checked timing before in my old ca18 and it involved using a magnetic field timing light, may cost a bit more but the use has been great.baz wrote:You can hear pinging quite easily, But if you don't know what pinging is then your simply fucked!..On the other note, Cars that run coil packs & no dizzy, You can't check the timing unless you have a computer hooked upto it, So basically what I did what my r32, 180, s13 etc was to advance the timing bit by bit until I heard pinging, Then backed it off the slightest

Exactly right.
Its a seriously ghetto method of setting timing that came out of the dark ages. You could get away with this method back in the old lower compression, higher octane fuel, points/coil pushrod carby days and achieve acceptable results but should NEVER be relied upon other than to get the engine running initially on a modern high BMEP engine and particularly a forced induction engine.
Thing with detonation is its occuring well BEFORE you can actually hear it! Is why so many engines are lunched even tho the driver did not report hearing any pinging at all!!
Any half arsed dyno tuner will use a dedicated knock "sensor" (microphone) attached to the engine with sophisticated acoustic filtering and listening thru cans (headphone) to block out outside noises.
THIS, is the only method of listening to detonation that can be trusted in any way in the longer term.
Also, different engines transmit pinging sounds differently, some are very obvious and others, like my VG30det are very subtle.
A decent inductive style timing light will work by simply clamping the pickup around the coil wires from the ignitor.
There is enough of a pulse there to read off.
For those who are really cheap arsed and only spring for those 2 bob inline type timing lights, just unbolt and lay the coilpack on top of the motor and using an old plug lead or 2 connected up and read away. How hard is that?

Not so much the big bang m8, Just a slow and painful death.
Just ensure your timing is correct BEFORE driving the shit out of it.
There could be a crapload of things causing ur strange running M8.
Look hard for air leaks in the intake, any pipes and hoses left off letting air in.
The list is endless.

car now burns burns a fair bit of oil FML!!Hello ladies and the gentlemen...update on my pulsar...
I know its been a while...since last time i posted something....but i only bring good news...
my car runs like a champ now...smooth like jaguar...so no more issues with the engine...
stuff i had done ever since last time?
-wire tuck
-painted engine bay
-battery relocated in trunk..because all the kewl kids do it..
-new stiffer rear suspension..still to do the fronts
-no more taped fenders..now just no tape..welding them together as soon as the front suspension is done.
new wheels...14x7 supra celicas..
-roof rack =)...just because...more downforce...because i totally need it...because i go so fast...lol...anyways...
-repainted bumpers and grille with plasti dip...good stuff...
-removed all uneccessary emmissions control bullshits..
-new full custom made exhaust piping..
-tinted headlights and tail lights..
-new shifter..not major..but wat the heck..
-brand new and poly utherane or urethane somthing filled motor mounts..lol..
man...now that i look back..thats quite a lot...and its almost at its peak..i'm happy with the power..even thought its stock..
why...because it's faster than most 80's cars..faster than a shit load of 90's cars..and some 00's cars..offcourse 00's cars rape me on straight aways...and civics cant touch me...
anyboo...i think i'm at the point in which i wanna get a new car...so i'm thinking...
The E30 BMW..drift the sheeet out of it.. =)
and now for the best part...some pictures!!!
ENJOI!
