Hell yeah, looks good. Did the Cyclone intake bolt right up?? or did you have to do some modifications?? At first I thought that was an entire engine from a Cyclone. Any significant differences??

Re: VortecFiero rebuild thread (56k friendly)
 

Not bad, got more pic's of the setup/ car?

Re: VortecFiero rebuild thread (56k friendly)
 

Yes yes, Im in for some non 56k friendly pics.....

Re: VortecFiero rebuild thread (56k friendly)
 

Nice build..... I drove the infamous shaun41178's turbo formula 2 weeks ago... the fucker boogied..I can only imagine a 4.3.


Nice to see another Fiero owner who isn't interested in car shows and polishing paint.

update
when I relocated the turbo I knew the range shifter cable bracket that
also holds the clutch slave cylinder was going to have to be massaged
I cut horizontaly then met that cut with a vertical one efectivly making
a 90* slice. I moved the cable portion bake about an inch and lowered it
about a 1/4 then rotated it clockwise a few degresss. I drilled and tapped
for a 3/8 bolt to lock it in place for mocking up. My welder guy told me
cast aluminum is a bitch to weld with out warpage and pores opening up
and made some suggestions about V grooving it for a better result.

the first few shots are "as is from the welder" the installed pics are after
I filed and sanded it a little.

Re: VortecFiero rebuild thread (56k friendly)
 

I used an adapter that mates a SBC to the fiero trans
and pretty much fabricated all the mounts etc

the engine is a '95 L35 CPI engine
base hp is 200 @ 4600
base torque is 260 @ 3500
to that i added the Syclone intake etc

the base Syclone engine makes about 170 hp (no turbo) and about 300 with turbo


i have a ton of mini projects on the go with it and will post as i start to complete each stage
most of this setup was in an 84 SE before it got too old.. and so im posting about the changes
and the install into the '87GT

Re: VortecFiero rebuild thread (56k friendly)
 

Have you used the/a, water/meth injector before? What's the controller like with that Unit. I'm using a "coolingmist vari-cool II" set-up on my rig.

Re: VortecFiero rebuild thread (56k friendly)
 

yes, its a devilsown... I have set it to start to come on at just before 5lbs and ramp up to 100% @ 10lbs
i run mostly windshield washer fluid and it dropped the iats over 75* on a hot day... i havent data logged it
but KR went from 12* to 0 and that you can feel.

redid the exhaust to a dual system
3 inch down pipe to a Magnaflow Camero style universal fit muffler
then 2.5 in pipes to the tips which came with the car. Im not real
big on the tips but they seem to look ok on the car

We need a HMT fiero club.

I have a HMT sticker on my turbo fiero, you should add one vortec.

erf

awesome build. should be one hell of a ride. is the conversion just different mounts for the vortex engine? how does the trans mount up? love these cars but now that pontiac is gone there expensive... been trying to do this to a fiero for a while..... gl on your build. cant wait to see more pics/vids.

the vortec is basically an up dated 4.3 v6
the mounts for the origonal 2.8 are nothing like it so I had to design and fabricate everything
the trans will take some punishment but the secret is not to have too much tire... id rather
lose a bit of launch than grenade clutches and transmissions.

once rolling i can hammer it and things stay together lol

intercooler mods done

I'll pass on even remotely having something in common with your halfass build.

Aaron where can i find a post on your build up...
did a quick search and came up with way too many posts to go through each one... you're a busy guy lol

thanks in advance

Sorry, here's the build thread. I was busy, I haven't done ---- for the past year but worked and bought a new car lol. I really like the upgrades to your car by the way, I'm not completely sure what all is knew, but your hotside is very well designed, amazing how similar it is to mine, puts the turbo in nearly the same place. Your wastegate feed is in a good place, wastegate is close to the turbine, and your new exhaust is really good looking! Wish you could have kept your trunk, but for people that don't need the trunk it's 15 lbs of unnecessary weight. I always liked the SyTy's, for just 285hp they pulled like freight trains, and just exploded off the line.

This is the current N* build, friend's car and build but I did the headers:
