PEZi720... the build thread

[Project Trucker]

interesting huh i wasnt sure and when my buds at school asked if i was gonna put a turbo on my truck i told them i didnt think i could find one or put one on a carb engine thanks for the info tho i learned something new lol

[lil89ram50]

but remember these stock z24's arent made to be turboed, and would pretty much fling apart if done so..........

[PEZi]

^ very true

I beg to differ. The club I was in turboed several types of engines with exceptional results. Because of the quality of fuel in those days we had to limit the boost to prevent detonation. The key to turboing a n/a engine if fuel regulation. Fuel pressure must be set to prevent the float chamber from drying out, so the increase in fuel pressure to the carb will prevent the forced charge of air from blowing out the fuel from the chamber. We have done - Ford Cortina 2.0, 2.3 Capri V6 2.8 - Nissan L18, L28, A15, CA16 - Mitsubishi sirus 80 (thats a 1.8) and a Chevy 350 which we installed in a 75 Escort. In most we did not drop the compression and ran a maximum of 7 lbs boost. In the Cortina 2.0 and the L28 the compression was dropped to 8:1 and the boost increased to 15lbs.

ok so i suppose you could run a turbo, but would it really be worth it? i mean after you spend the time and money? cuz ive heard its not too safe to do it to one of these motors, so i would guess no more that a few lbs to be safe.... so i think it would prolably jus be easier to switch to a ka/t.....

[PEZi]

it'd be more worth your time to do KA-T

[Project Trucker]

man i just had a simple question and now i got all these results awsome thanks for all the answers etc. i dont think i will put a turbo on my truck tho im working on getting more style and fuel efficiency if i ever do anything to my truck i might get a fuel injection engine with a 5 speed trans.

[breadbox]

wow great read, liked the carb'd turbo info.

I should be tearing into the KA24e and Z24 heads soon after I get my tools back home from my friends tomorrow.

Then I will flood you with pictures of blocks, heads, and measuring devices.

At the latest I will have them cracked and compared by the end of second weekend in November. If I wasn't going to be in two weddings in that time period I would do it sooner. Let me know what you want pictures of and which comparisons you want first. The KA should be easy being its just the long block.

[GahannaKid]

Do you still have the old interior bits from before you stripped it?

[PEZi]

i still have the passenger seat... that's it

most of it was pretty faded, cracked etc...

[flinterman2000]

The additives in the gas react with the type of material used to make the impeller. You will normally see streaking first (a groove cut in the face of the impeller as it forces the gas out of the housing. Then pits appear. Sometimes you get a white build up that looks like aluminum thats been heated and left with out using for a long time.

i still have the passenger seat... that's it

how do i get the backrest off on the back seats mines an 84 king cab and the backs atatched to the sides of the truck and the seats flip bown im sure there the same..seats out but how do i do the backrest

[PEZi]

i think i broke the backrests off... i didn't care since i wouldn't be using any of the stuff again

i think i broke the backrest off... then removed the interior plastic... then removed the bolts that held the backrest on

the backrest is attached by bolts... but from what i remember you can't get to them to save your life

[lil89ram50]

there is 2 bolts on the bottom, then you have to slide it up, the top is just clipped in! use the force!

[PEZi]

ahhh.... that's what it was.... i think i broke the clips pulling them out

[bracktheron720]

perfect thanks guys for the help!!

[bracktheron720]

any thughts on gettin rid of the fan on the motor for an electric one??i know the create drag wouldnt it help the motor spin a little easier??if you have any info on doing the change over let me know id like to do it..

[PEZi]

a few of the guys here have done the electric fan... not 100% sure what i'm gonna do with the fan yet for mine though

[bracktheron720]

a few of the guys here have done the electric fan... not 100% sure what i'm gonna do with the fan yet for mine though

do you know how the fan and clutch thing comes off and would i just wire the electric fan to come on with the ignition switch on??

[PEZi]

you can wire the fan to do what you want... you can have it turn on when the thermostat gets to a certain temp... by switch in the cab... whatever really

the old one comes off by unbolting it... if you take a look at it you'll prolly see the bolts pretty easy

[flinterman2000]

I'm doing a fan delete with the engine swap. Will post the process when I'm done.

[PEZi]

anyway... after changing classes... i no longer need to retain ANY of the stock pieces besides the subframe... so i'll be making a full custom suspension for it with some help from harbor freight

the engine build will be 13:1 compression, lots of headwork, valves etc... ITB's and some sweet FI

[bracktheron720]

Harbor freight??what from them is gunna help you do a custom suspension??just curiose...

[PEZi]

stuff to cut, weld and fabricate with... good times lolmore specifically... a welder, a press, a band saw, a chop saw, a right angle grinder, a drill press, mini lathe... that sorta stuff

[bracktheron720]

Awesome!!!sounds good to me lol gotta love the prices over at the harbor frieght!!!!cant wait to see how it turns out!!

[PEZi]

so.. i finally got some decent pics of the guy i have to keep up with in my autocross build... he took second nationally and he's local... his car is classed the same as my truck

EFI dyno tune

beastly engine

repainted and ready for action

[bracktheron720]

thats a pretty sweet ride!!i would have to say that our 720's are way cooler though!!lol

have you ever ran with this guy and if so how much different were you times???what im gettin at is how much faster is it than your truck im sure it is that things a full blown dang race car but.....its cool to know how these trucks do agenst cars like that!!

[PEZi]

well as of right now.... i got no chance in hell... he's already got his full custom suspension as well as full engine build done

he makes 150 more hp and weighs 1700 lbs... and he's on 275 width hoosier A6's

the times depend on the track cause its always different.... but until i get my build on the suspension done as well as sticky tires like his... nowhere near the same times... the last event he was 6 seconds quicker... which is a lot considering i ran 44 seconds to his 38

[bracktheron720]

oh yeah just by the pics you posted of the car you can see theres a whole hell of a lot goin on there!!!!iv had my truck for a while now and just recently stumbeld apon nicoclub and up until i did i had no idea anybody was racin a 720 and its cool!!!iv already started rippin stuff off and workin on the suspension got rid of alot of stuff under the hood with alot of help from you as well as a ton of other people on here!!i cant wait to see your truck stompen cars like that and i hope mines not far behind!!Lol are you drivin your truck daily or is it track only????

[PEZi]

well... its technically track only... here in CO it can't get around much this time of year and without lights etc it can't get around much period... but with that said... it is my only car so i try to drive it at least once a week to get everything flowing and stuff and i do drive it to the track
