Thread: 3.4 pulley too agressive with gen v swap? 2000 gtp

Ok, so I have researched alot on the e85 and gen v swap, in regaurds to pulley size and knock. I am sorry in advance if this has been posted to death, just would like some input from memebers. I would Like to thank everyone in advance. Although I dont post much this website has been more than helpful with my build! So thank you to all those who take the time to help everyone. I have a 2000 gtp, swaping to a gen v, My question is what pulley can I run and not seen knock. Everything I have read is the gen v is = to about .2 drop in pulley size. I do have a areoforce scan gauge and currently running no knock on my 3.4 setup. I also will note that I am switching to e85, and have a tune lined up shortly after getting the swap done! I will have to drive about 60 to 70 miles to tune the car. The e85 fuel will be changed during the tune, and currently running 93 octane. My cars mods are as follows.1 *Thanks again to everyone who reads this and everyone who posts to the site. Truly have enjoyed building this car, and it wouldn't have been possible without this site and the information in which it provides!*

2000 gtp 2 door coupe:

mods:

3.4 pulley currently on mps
1.9 zzp rockers
CAI
104 autolight plugs
trans go shift kit
zzp 1.0 pcm
Ported l67 zzp throttle body
L67/gen v adapter plate
aem wideband
areoforce scan gauge
gen v (getting put on now)
#60 lb injectors (getting put on now)
SD headers
180* t stat
e85 (which will be done at the time of the tune)

I also have a 3.6 pulley and belt which I could put on for the drive to my tuner, which was what I plan on doing. I will take the 3.4 pulley with me and see if I can run it. Guess my question was anyone out there running a 3.4 on this set up? Think i can? or will I need to put a intercooler on it to see no knock? My hopes are the e85 will allow me to drop to a 3.4 and add timming. just curious on anyones thoughts or experince with this, Thanks again everyone

on corn you could run a 3.0 no problem. no ic needed when using corn. ic is for 93 octane gas and sub 3.4 pulleys.

and if you need to drive to your tuner, change the injectors when you get to him, cause it wont run right with 60's untuned on gas still.

i ran my car with gen5 tog headers 60# injectors on e85 and 3.4 just fine didnt have any issues with it and the car was sold on sunday so i dunno now. i told the guy it was on e85 sent him the gas pcm also and a bigger pulley too.

yes my car was tuned for the e85 amd 60s though.

im just saying a 3.4 will be fine on e85 and those mods.

3.4 would be fine, but why short change yourself when you can go smaller safely?

oh yeah some tuned 60s absolutely id go smaller 3.0 should be doable with rockers and e85.

your mod list will put you about 300 hp, ( with the 3.0) and thats putting you right at the trannys limits. if you drive it like you stole it all day long, you will be getting a new tranny sooner then later.

you and i got the same mods pretty much, but im on gas with a ic and 3.2. once you drop under a 3.4 your never putting the 3.4 back on. a 3.0-3.2 the power level is turned up to an addicting amount of power lol

news flash, that gmr 1 inch chain might cost you 2 grand on its own. you cant find em no more. they are worth more then gold now.

id not get a higher stall for daily driving. you would need a input shaft at the min as far as upgrades go. tep is where you want to go tho. and if you do get his valve body too.

im pushing the 300 hp range myself, my tranny is a used 150,000 mile tranny i dropped in there 10,000 miles ago with a new 4 th hub and a shift kit. i squeal the tires easing into it off the line still. some times it will shift early on me, cause sadly, its not wot and spinning a bit still.

rule one is no burn outs. that will kill your tranny quick. its not the spinning, but the suddon stop of the burn out that will snap parts on you.

also the 3-1 shifts, if you hammer it and down shift into first hard a lot, bye bye input shaft. ive broke the wheels free and smoked them at 30 mph by accident passing some tool bag. i think i showed him lol never did that again either, dont want to.

oh yes you will lol you cant help it. and when your tuning it, your gonna need to do a few wot pulls.



waiting for them #'s. wish i had a dyno place near by.

run the gas real low, have a 5 gallon can of e85 at home? add that, do your pcm and injectors and what not, run that low again and fill up with e85.

Don't forget to change the fuel filter 157 times.

Fixed it....

You will like corn.... your car will like corn....

Timing is great and all but my car likes boost more than timing with corn.

Who is doing your tuning? (I only ask because you are in my area and Im curious)

I hear there is a white sedan for sale that makes turbo noises but isn't turbo but it's quick enough with a FULL interior.
