Like I said, check out V8archies.com They have alot of info on this subject that you need to read, and a lot of links. here is a link http://www.v8archie.com/v8fiero.htm Just thought I'd help b4 you try to re-invent the wheel and all. enjoy

people are talking lots of ---- on this one. first of all there are sevral stock GM ecm's that can run that n* DIS system and control fueling. a tiny bit of wiring but nothing to drastic. as for the engine itself. its fiarly robost but id use a 94 up block there better quality using a squezze molding process that removes porosity.

pistons etc might be high compression but its a very good pentaroof style chambe and is known for easily resisting knck with proper spark/fuel tunning.

i wouldnt anticiate much trouble in running 8-10 psi of boost on it. however a turbo charged quad 4 would offer better power lighter wieght and les effort to fit and would keep the car from understerring. for that matter you could also turbo the existing 2.5 ohv engine and make good power unless you have a 60*v6 in there and those 2 can easily make some obnixous power as well if you know WTF your doing.

I agree with the quad four comment. Awesome motor. 180 hp stock (w41 was 190), and with low compression pistons, better headgasket, 8psi, youll have a blast!

OR, go with a 2.4 LD9 Same as above, with more reliability but 150hp, 155 ft lbs. There are a few cavies on here with that motor boosted and many on jbody.org. There's just something about the 2.4 that i love.

btw, WTF are you tryin to do, tear the pavement off the road!? 500 hp isnt good enough>?

I like the "quad 4" it powered a 1990ish cutless sumpreme to a 150+ mph top speed in an old *** motortrend mag.

The 3.8L would be my choice. The Buick grand national engine can hold almost 600hp STOCK... STOCK !!!! ( the turbo trans-am that was powered by a GN motor is not only the fastest prodution transam ever built, but it had shorter cylinder heads to fit between the strut towers, but of course it was a pretty limited prodution )

And just to clarify the Cyclone S10 was powered by a 4.3L chevy motor, not a 3.8L buick motor. The 4.3L in the cyclone was far weaker than the Buick. Noless the cyclone still holds the recond for the fastest prodution truck built. ( lick my turbo powered ***** dodge SRT-10 Ram!! )

The bad news is that GN motors aren't cheap or common. I was going to pay $1000 for a 80K mile one that was set to be installed in a mustang.

SSOOOO in the case of the ferio I'd say a GN motor with a VERY large turbo ( lag = power delay = tranny lives ).

The LS-1 is a sick bitch too, but its big $$$ too... How come GM comes up with great motors and kills them b/c they are greater then the vette.... I'd like to see a turbo6 in a vette, but the Z06 seems to be doing fine, haha .

well for all out show and go an aluminum ecotec would be a better choice. and Mother GM has blessed this engine with light wieght a decent block and plenty of after market hp up parts. woo woo. either way id stick with a 4cylinder a v6-v8 = feiro not sterring worth shiit.

Well this is gonna be my looooong term project, I want to make it look like a Porsche GT1 with my own customazations. Actually a V6 fiero can come stock, and a V8 only adds about 85lbs extra on average. So even if I was like 300 lbs it would stear the same almost. I will upgrade the brakes and the suspension so no real worry there. Well how much HP can i get a LT1 with mostly stock internals i would upgrade if i can find a nice price, but for now this is gonna be on the cheaper side. What about a nice tri-turbo, like two T-25's and maybe one quite large turbo for some nice top end. I know lag is also an issue but i as alot of HMT'ers say "You call it turbo lag, I call it burnout control." All I am saying is once i get moving i will be moving. Quadnie, where did u get you LT1's and any one where would be a nice place to find them. Any one have any suggestions to me, like where to get parts, any other things like that.

Thanks,
Tom

a gt1 body kit, now you're talking.

I personally would go with v8 power, with some nice trick flow aluminum heads and weight saving here and there you should be alright.. you could always thow a fuel cell towards the very front of the car for weight distrobution (well maybe not in the very front, don't make it a Pento.. but I'm sure you'll figure it out).

The motors we found were the Gen2 LT1 blocks found in 94-96 caprice's with the police package (also the pimp impala SS's). My best friend's dad owned a good sized salvage yard and used to goto the state auto auctions every week in orlando and pick up wrecked police cruisers for a couple grand, strip the motor + tranny for personal use and let the heathans take whatever small parts they wanted from the lot. He then would throw those bad boys in full size (mid 90s) chevy trucks that would scream. I remember the hardest part of the conversion was the ------- wiring harness which had to be custom ordered/made from a place in texas (or CA i forget) then on top of that they were ALWAYS ON BACKORDER. The projects did take some time, but the man knew his ---- (used to race nascar back in the day) and would make one mean machine for us to play with.

The hard thing now would be finding a virgin (un canabalized) wrecked 94-96 police cruiser (or impala SS) to be a donor. Yes you can always go all out aftermarket for controlling the thing and other options but it was nice having the donor right there to pull parts off of.

My long term dream was to equip my sleeper volvo with an LT1, but the hassle of the electronics conversion, availability of the block, limitations on creativity has just shoved me into finding an ideal sbc block.. an all steel block would be fun to handle some high boost - They mostly came in the 327s but also a few were in the 350s.

I would seriously consider just picking a nice high nickel content (or find an all steel) sbc and just working that motor, make it a stroker or whatever you want. You can always add fuel injection management for about a grand that is data logging capable and very programmable for boost.. just might be cheaper to get a complete stand alone aftermarket setup versus messing with finding OEM (or cloned) corvette parts.

You can yeild as much HP as you want from any motor, ---- many "crate" specials roll with 500HP on pump gas.

Whatever route you want to do, let me know what motor you would like to pick, I will tell ya what I think about it.

I supose i will look for a LT1 from 93-98(i think) trans-am's, camaro's, and Impala's. The first thing is the engine, then suspension (which kinda happends the same time as the engine, then i will start making the fiberglass body work. Latly i have been using Rhino3D to design parts of the car. I haven't gotten to figure out the program that well but i am trying to teach my self with what little spare time i have. I also just picked up a book for fiberglass working. I guess for now i have to just look for different car's in my area and such for parts. Any comments would be appriciated.

Thanks,
Tom

Hey, just looked around a bit, found some usefull info if you decide to hunt down an LT1..

First off, find a car that is pre LS1 (pre 97) Some LT1s surfaced in the early 90s, but that would mostly be in corvette bodys. Check for 94-96 Caddilac Fleetwood, Buick Roadmaster and of course your F-body cars in that year range.. We had like a '96 Trans Am in the shop with a six speed, it definately had the LT1 in it (I would assume they only mated the T-56 tranny to the LT1 block). I think the police edition cars just had a beefed up 4L60-E (computer controlled 700r4) auto transmision, but then again every light truck/passenger v8 automatic chevy since 1987 had the 700r4 (4L60) variant in it. I could go on and on about the 700r4 but that would have to be on a different thread

There was also a 92-96 LT1 aluminum flavored block, but my guess is that would be under the vette hoods.

Think about this info, let me know.. like I said, if you aren't going to go with the LT1/LS1 block then we can talk about some good alternatives (which would be my choice in the matter).

I would not pay more then a grand for a running lower milage (under 100k) LT1, that's just what I've heard the guys who buy them on all those F-Body forums say.
