I don't know if your aiming for more power, but you can put a whipple on the 3800s. It should bolt to any intercooler according to the sight that sells it. Its much more efficient than the Eatons and can pump way more air.
Saboo 57, I have an 88 GT. I will be doing the 3800sc swap in March. I live in California. I know I can't do a whole lot to it without failing smog. Where do you live, and what are your actual 1/4 mile times? I plan on using a 3.4 pulley and a genV m90. Any track videos? If love to see them. Nice car man. I live the natural look of the Fiero. I don't understand why people turn them into Lambos and Ferarris (and not install the BMW v12). Lol
@ToothFairyExperience I'm in eastern PA, about as far away from you as possible without leaving the country, I'm afraid! I've never put the car down the 1/4 mile, mostly out of fear of grenading the stock Getrag trans. I can assure you that even with an unmodified 3800sc, you're going to have a ball with your car. If you do a search for supercharged fiero, the vid of the street racing with an eclipse is this car w/ original owner. it's picked up 50hp since then.
@sabooo57 eastern PA, huh? awesome fiero! thanks for the motivating vid. i'm cental PA and just picked up an 88 gt. I'm planning on doing the l67 swap this winter. did you do the swap yourself...any tips? do you know if the wiring "plans" on gmtuners is accurate? seems to good to be true that someone put the pinout to pinout wiring diagram, and that it's accurate. did you buy motor mounts, or fabricate? i've got the getrag in the car, but i think i'll go with a 4t65e-hd for now...
WTF are you smoking? I would put $100 it was a dynojet. If it put down 364 on a loaded dyno, then props! Get your head out of your ass dude. I have the exact same setup and mine put down 315 rwhp and 335 ft/lb torque on a loaded dyno (Mustang)
@Rare87GT@Rare87GT - yes - Dynojet for sure. The engine is a bored 3800 block from ZZP with a ZZP hot cam and ZZP intercooler, aftermarket valves springs and rockers, ported intake, 3.0" pulley, ported SC, SS Autochrome headers, custom tune, PRJ fuel rails, , northstar TB, 42.5# injectors, dual cam chain, and a few minor things beside.
These were tuning pulls, and I think there may be another 5-10HP hiding in it, but until I find it, I cant say for sure.
Hey man...I wasn't trying to be a jerk I was just wondering. The guy below me had to be kind of childish. I have the exact same mods.....only I'm running a 2.8" pulley, XP Cam, MLS Head Gaskets, Manley exhaust valves, slightly Ported Heads, 130 lbs valve springs, ZZP Pushrods, ZZP Stage II Intercooler, 42.5 lb injectors, TOG Headers w/3" exhaust, N* Throttle Body, LS1 Maf, Meizire Electric Water Pump, Walbro 255 l/hr, PRJ Fuel rails, Ported Blower/Intake. I'm running the 4t65e-HD
@Rare87GT yes and every body knows mustang dynos are shit tthey read 300 whp but on a real dyno ud get 260 maybe u aint got no ride or ud know what kinda dyno that was
ive never run my rx7 on a mustang dyno cause i know its a name and nothing more dyno jets are for broke shops with no money wow this noob watches too much hp tv now he thinks hes a car guy
hey the trim that is black that goes around the car, did you paint yours or did you order it somewhere. if so where. and love this beast, hell of a ride
I love the 85GT's - I'm thinking about swapping an LS7 into one once I recover from this project. I did 2 pulls, both were in the 365 - 370hp and 375-380tq range.
I have about 11,000 into the swap, which includes alot of extras and power adders, and misc goodies. It also includes alot of labor, as I paid someone to do the work.
How much power did you put down? And how much money do you have in the engine and swap? I have an 85 GT that I want a 3.8 in. Also; what trans did you use?
i'm not actually central PA, but i do reside there.
