Real Fiero Tech

Sorry meant 3.27 rear gears

The engine builder also offers a similar setup with vortec heads. I might go that route and get the vortec HSR

87 IROC. Orginally L98 700R4 373 gears

Well I tried that and all I heard was "put in an LSx"

I am 100% aware of the existence of dynos....just trying to get input before I spend thousands on an engine.
HP guesses on this engine with a Stealth Ram?

Cam: 218/224`@.050" with .500" lift on 112`LSA
ported L98 heads
383 stroker
30# bosch injectors
255lph fuel pump
52mm throttle body
SLP intake runners

Power guesses?
Thanks

While I understand where you're coming from, have you priced LS engines? I already have the heads too

I have the chance to buy back my IROC from high school.
I am thinking about a rebuild with stock vortec heads, a Stealth Ram and a cam.

What cam would you recommend and will this be a decent performer?

The size of a 4.9 is the only concern I would have. It's fairly lightweight though. I;d definitely have to figure out some gear solutions then

The automatics had 4.62 gears if I am not mistaken

I have a 1997 Tracker with a barn-burning 96hp 16 valve 1.6. I'd love to put a more powerful 4cyl (ecotech or ka24) or a 3400 while still using the stock 5 speed transmission. If you fab up an adapter plate to mount the engine to the trans, how do you handle the input shaft and other trans issues? A...

If you asked me to describe a very shitty early 3rd gen TA, my description would be JUST like this.

I am pretty surprised to hear this. I felt like the 3500 and 3900 were going to be the "new" Fiero swap.

He does that to screw with you, but I guess it goes over your head.

Can we please ban this tool too?

Injectors are the stock 2000 3100 injectors which I believe are Multec 2 22.5 lbers at 55psi.

Can any of your files control the 4t60e with the multec 2, higher pressure injectors? Or can your 99 grand prix bin be changed to match those injectors? Edited to add: Found low-mileage 4t60e from a Buick Century. $250 Shipped to my place of business. Let me know if you think I should go ahead and j...

My 3100 is the large-port 3100 with the 22.5 lb 55psi injectors. I want to pull the wiring, computer and trans from a 2000+ Malibu, so those files should work. 440t4 is what I meant when I said 4t40. I have seen them called that on other forums (incorrectly). What axles would be needed for the 4t40/...

I am considering using the 4t45e with my large-port 3100 swap.
I believe it will mount similarly to the 4t40 swaps.
My question is about the computer. Can I use the wiring harness and computer from the donor car instead of trying to find a non-electric 4t40 and tuning a '7730?

Does anyone have any pictures/plans of exhaust setups for 3x00 engines, using auto trans and the 3x00 manifolds, not the Fiero ones?

Thanks

So using the BURN2 and TunerPro RT, would that be all I need? For now the car isn't going turbo, but I will be using the DIS. I am using the 3100 heads and intake. Would the turbo gran prix map be close enough to get the car running? Engine is a large port 3100 170ish hp and 195 tq from a 2000 Lumin...
