PEZi720... the build thread

[seang]

Hi Pez, I was wondering if you are still running the clutch damper. The reason I ask is because a guy on another forum I belong to was having problems engaging 1st gear. Someone suggested that he bypass the damper, and he did. He said that it really helped.

[PEZi]

still got it... never really understood what it did and never had any reason to remove it... mine engages into 1st very easily... even if i'm moving all i gotta do is rev match it

[seang]

That's good. I remember the ---- in my old 86.5 would grind on a fast 1-2 upshift, and I think I could have fixed that by removing the damper had I known better at the time. It would also miss 3rd gear and go into 5th if I tried to shift it really fast. I used to think it was the synchros, but I'm not so sure anymore.

*Edit* According to Nismopu, naps-z used a FS5W71B, and not the FS5R30A

i had a slight issue with the 1-2 grind when i first got it... but it was because my clutch wouldn't go in all the way with all the carpet and floor mats and padding going on....

all works fine now... however i have dented my firewall from pushing the clutch in so hard

[seang]

Have you ever ran a slalom course?

[PEZi]

yeah... there's slaloms in every course we run

[pejsa s-13]

hey pezi did you go to lincoln or something?

just wondering where you got your understanding of vehicles.

[PEZi]

as in school?

i've been involved in many school related clubs like SAE and such.... ya kinda pick things up along the way

most of my knowledge relates to subies and bimmers... done a fair bit of work on both... but i also learn things from the guys i talk to like the guy in the corolla above... he's the one that gave me my suspension ideas for the future

[pejsa s-13]

fair enough im enrolled for uti next year but im coming out there to check lincoln out before i make a final descition i am deff not going to wyotech though

[PEZi]

yeah wyotech is lame.... i learned a lot at the colorado school of mines but the school blows... i go to the colorado springs campus for colorado university now... and i'm part of a baja project so i'm learning a little bit of the offroad stuff now

[lil89ram50]

hey pezi, jw how you did your power steering delete.... did you jus cut the steel hoses and crimp the ends?

[PEZi]

hey pezi, jw how you did your power steering delete.... did you jus cut the steel hoses and crimp the ends?

make sure you get most of the fluid out and just leave enough in the box to lube it... otherwise it will too hard to turn the wheel to do you ant good

but yeah... you can cut and crimp or loop them

[lil89ram50]

is there anygood tricks to getting fluid out?

[PEZi]

nah... not really...

i just unhooked the lines from the box and then went lock to lock on the wheel until no more would come out

[PEZi]

update time!

i just got my new seat installed... bought it used (if you look at the pics above of the AE86 corolla... it came from there)







and i got my hitachi off.... weber 38 DGES is in the process of being installed

[PEZi]

and...... the carb is on...... sorta

gotta find another tool to tighten the 4 bolts to the baseplate down... i got nothin smalll enough

an arsenal of tools and i still can't find one for this job

anyway

[PEZi]

and..... it runs

not tuned yet of course... and it doesn't have the air filter on it because they sent me bolts instead of nuts to tie it down

but... it already makes the hitachi look like s***

here's a vid

Dang that sounds sweet!

So you are running custom exhaust, the weber, and hi-po wires, ...what else?Is your motor bone stock internally?

I'm asking because I have a '84 720 with a Z24. I just replaced the valve guide seals with the head on the motor using compressed air. I now know there's head-gasket leak in the #4 cylinder.

Im wondering whether its worth it to fix the HG leak and try to do an inexpensive rebuild while in there or just to run it as is. The truck is a $700 210k beater that seems to run strong except for the smoke when cold.

What do you guys think? Is a KA head a reasonable swap thats do-able and worth the trouble? Do i just run it till its done and ditch the Z24 completely?

Thanks!!

[PEZi]

KA is doable... but just what i would personally do if it were mine... while you're in there doing the headgasket, do a little headwork too.

it wouldn't be too expensive... just shave it a little... then port and polish... that'll make it breathe much better with a little higher compression... overall win

since you asked... mine has the weber, custom exhaust including headers, wires, pulstar pulse plugs.... and it weighs basically nothing

its basically a go-kart

[jtbenfie]

so a z20 head is a better flowing head than say a z22 or z24 head? I assume the heads can be swapped between engines?

[marleyone]

Pezi,

WoW your motor sounds great for a free breathing stock Z24! And from the autocross videos it looks like it puts out pretty good power too!

[damn]

What is your fuel pressure at?

[PEZi]

it sticks around 3 mainly

OH... and the more i advance the timing the better... still no pinging as of yet either so i'll be advancing it more when the weather gets better and i continue tuning

[damn]

So when your dial is set at 3.5psi it read's 3psi?

Im trying to compare our trucks to see if im the only one with that wierd problem.

Doesnt the carb just love advanced timing!!

yep... it drops to about 2.5 psi at full throttle at high rpm... there are 2 reasons for this.... 1 is that the fuel kinda bypasses the gauge as it goes to the carb (because of how its tied in) and 2 is that the FPR does limit the flow a bit... i've double checked everything and it all runs good so i'm leaving mine on

and yes... it LOVES advanced timing

[damn]

Your not afraid of it running out of fuel with it being advanced like that?

[PEZi]

nah... cause its definitely not lol

[PEZi]

well... the timing is really getting up there now... i think i'm almost to the extent of what i can run but have yet to experience any pinging

runs better every time i drive it... but the idle is still a little off.... don't care tho

I was able to advance my timing until the distributor wouldnt go any farther but i starting pinging so i backed it off! Im going to buy a timing light to see where im at!

My idle is weird too i think it has something to do with the truck and the emission's.

[flinterman2000]

Advancing the timing too far with the emission set up is what is causing the idle problems you all have. Remember the engine is designed to operate with 3 degrees BTDC to about 5 degrees ATDC. Too much advance and you'll get either post ignition or the cylinder fires too early at idle.
