My name is Rob and I am the Owner/builder of a custom carbureted Vortec V6 powered FIAT 124 Spider.

The engine features a comp cams 280° duration .525" lift hydraulic roller cam with retrofit hydraulic roller lifters and true roller rockers in an 85 block bored .030 over. The heads are Vortec fitted with screw in studs and pocketed for the taller springs to accommodate the higher lift. The 4bbl intake is an Edelbrock 2114 topped with a Carter 625 cfm AFB.





The body and taillights have been customized.. Currently the car is painted satin black. When I'm done building the car and testing it I'm painting it house of kolor organic green Kandy. For more pics of what I have done go to http://www.v6spider.com
This is my second build of this car. The first one was crudely put together. This version I'm doing as best I can to build it right. There are many other things I did to accommodate the v6 in the spider Customized front suspension and cross-member plus many other modifications were necessary in order to make this happen.. Anyway. Hope you guys like it.. :cool:

Cheers!
Rob

Here's a shot of it on it's side in my garage. I re-enforced the subframe and converted the rear suspension from a 4 link to a 3-link to accomodate the dual exhaust out the back. The rear -end is a limited slip unit out of an 84 RX-7 GSL.


Cheers!

Not much hookup... But lots of fun all the same.. The transmission is a Borg warner t5 5 speed from a camaro. The bell housing is from a Chevy Monza spyder.. Cable pull.. :evil:

Happy Halloween!

Nice, I like it. :thumbup:
Looks like it was made for that V6, nicely done!
Love the tail lights also.
Thanks! I removed the sheet metal around the bellhousing area and fabbed in new sheet metal to make room for the trans. I also built my own steering using a 72 mustang II rack the shocks are retrofit mustang II coil-overs for a mustang II made by QA-1. They are 12 way adjustable damping. The brakes are from the same RX7 donor that the rear end came from. Steering arms are custom made and lower control arms are modified FIAT.




The taillights are 2 1/2" Truck Marker lights that were modified to work with 1157 two filament bulbs.
The tailights holes are 2 1/2" exhaust pipe..

Cheers!

Cool, sounds great :D I want to see it done and on the road. :drool:

If you can find a different air filter that fits, do it....those foam things are known for catching on fire easily if the engine ever backfires.....they are also a very poor flowing filter.

Thanks guys. BTW I have to build a custom air cleaner so the foam one is out.. Not much hood clearance at all.. Like the spitfire... I'm in Washington state.. :)

V6,

I think your V6 Spider build is exceptional!

Looks like a lot of hard work went into building it.

The wheels...not a fan of them but they do give a stock/sporty appearance.

The wheels are enkei RP01's 15"x 8" with p225/50r15's in the rear and p205/50r15's in front. I was looking for a modern Ferrari like appearance so hence my choice. Stock wheel size is 13". I also changed the track on this by changing the offset as well as using a wider rearend. the change added 2" to the width both front and rear.

Took the beast for a spin.. Still some refining to do.. But on the whole the engine runs great! Squirrelly as hell but that is part of the fun. I'm waiting on a master cylinder and muffler and I should be good to go after that..




It's a diamond in the rough.. 8)

So over the past couple of weeks I've been driving and tuning my 4.3L Vortec V6 powered spider. For a quick reminder..
The cam is a hydraulic roller cam from COMP Cams.
225° duration @.050 lift .. .525" valve lift with 1.5:1 ratio true roller rockers. I've discovered that it likes no more than 34° total advance @WOT. Whether it's a v6 with a roller valve train or a 4 cylinder with dual over head cams the tuning principles are the same I think. Also having the fuel/air ratio gauge really helped with my tuning efforts.. I had to swap to a couple sizes larger jets in the primary to richen the mixture as it was running too lean. But I also discovered I had the timing too far advanced which was showing on the gauge as too rich. The overlap of the big cam was tricking me into thinking it was necessary to advance the ignition timing further than it was supposed to be.
