4Banger

[1FST2M6]

i've run nitrous on everything from Suzuki swift GTIs, jeep wranglers, countless corvettes, an eldorado and an automatic geo metro.. i'm sure putting a 42 jet on a 4.9 would put you over the 350lbft mark at the ground safely!

WOW! I din't know it would do that much. I'm really interested. We had a 75 shot ZEX kit for the CRX that we never got to put on because the motor (SOHC vtec civic Engine) supposedly has some 'High mileage' rings and everyone we spoke to suggested, even though not mandatory, that we swap those out before installation.

1st question would be if I can use this same kit and convert it over to the Four-Nine? Other question being, what exactly else do I need? I'm sure you reccomend some sort of fuel management to go along with this as well as maybe other misc. hardware?

Basically, I'm trying to politely ask you to spill an 'ingredients' list for what I need to put the nitrous kit on.

(BTW, I know not much about this subject) Thanks in advance, John.

You gave up on this forum???

Why? In my opinion, with the internet booming (useage is at least, not stocks), Fiero's are more popular than ever. In fact, get the July 2002 issue of Sport Compact Car Magazine, and vote for the 3 Fieros that are listed in the USCC Ballot. One of them is owned by V8 Archie himself. It's the yellow chop top with the suicide doors and the Z06 Vette engine in it.

Also in that issue, is the guide to junkyard turbos. I know which vehicles to get a T3 off of now. And so what if it needs rebuilding, I'm getting it ceramic coated anyway, and rebuilding a used one is cheaper than buying a new one, but the ceramic coating makes up the price difference, I'm sure.

WOW factor is right. If I'm gonna beat people in the USCC, I want it to be with a 4 Cylinder, not a clunky heavy V8.

And word of advice with the 3.4 swap, go with the Buick 3.8. There are more street legal parts for it (since it's been around since the 60's), and it has more torque with the same horsepower as the 3.4. The 3.8 has power at your command across the powerband, and it's made for boost, wether it's turbo, super, or NOS, it can take it, and it can take ALOT of it. More than the 3.4. The 3.4 is OK for lots of power, but reliability with Chevy's heads is the problem with the V6/60 blocks (2.8, 3.1, 3.4). Now if you go to spoperformance.com (GM's performance site), you'll see some beautiful heads, but none are street legal, all meant for NASCAR and off road stuff.

Ahh, the sound of these motors in fieros is unbelievable. Rev that thing out to 8k and listen to that F1 sound that hums behind your head. What a rush!

The 4 banger sounds like an angry hornet at 8K, rather than an F1 car, but still impressive. I wonder bout the 2.2 EcoTec and the 2.4 Quad though.

i've run nitrous on everything from Suzuki swift

Bout' freakin' time someone put performance parts on those things (Geo Metro clones). They weigh 1600LBs, and are asking for power. Makes me almost want to buy one.... almost.

you'll need engine management like a Tec3 or Holley commander

I've been looking at the Venom stuff for a few months now, and the one for S-10's should work, along with Venom's NOS stuff. Cheap, but still gets the job done.

I've been thinking about a small 50 or 75 shot on the 4.9. I've heard no opinions on what it would do for the block though.

Ceramic coat the piston tops, the chamber celings, and the valves. It'll reduce the heat by more than 100deg. and it'll add about 10-18% HP. $$$$$$$$$

--------

Basically, I know I want a turbo, just which one is the question. And since I know nothing about the science behind oiling systems, I may have someone else do the job. I can do the rest, but the oiling stuff leaves me clueless.

So any advice on that is helpful.
Thanks.

P.S. You guys kick ass!

[JohnnyFiero]

About the Rev thing, I was talking about a 3.4 TDC motor... But, you get your point across well on everything else.

About the ceramic coating thing, where can I find this kind of service? (I don't really know much about engine rebuilding places) Should I look towards a coatings place that does like powder coatings and such, or at the engine shops?

[fieroturbo]

E-mail me bout the ceramic, or look at every other forum I've typed in, cause this is the 10th forum so far with me discussing ceramic coatings.

Also, anyone who has tips on turbocharger oiling system design and hookup, and science, PLEASE let me tap into your brain....

with a Q-tip if necessary.

The easy way to do a turbo job if you don't feel like tapping into your block or oil pan, is to put an adapter between the oil filter and the block, or if you have an oil cooler, just interrupt it.

There are a few big things to look for in a turbo.

There are water cooled turbos, and there are oil cooled turbos. Water cooled turbos still oil for the bearings, and it does cool too, but it keeps your turbo cooler, and works as a secondary oil cooler. It will place a bigger load on you rad though. There is an internal water jacket around the bearing housing, which carries through coolant.

There are mechanical wastegates, and electronic wastegates. A mechanical wastegate is operated by a spring, with a preset pressure rating(1 bar spring opens at 1 bar manifold air pressure[MAP]).

An electronically controlled wastegate is opened by a signal. The signal is given either by the ECU, which reads it from a MAP sensor, or directly from the MAP sensor.

The best bet is to get a water cooled electronically controlled turbo. If you don't feel like paying for an electronic boost controller or a stand alone ECU, you can always just use a MAP sensor to trigger the wastegate to close. Of course, if you do ever want electronic boost control, you already have the turbo and sensor in place....

As I recall, Suzuki did make some turbo Swifts, they had some potential(turbo sprints too).

I like the 3400 TDC for it's Ferrari like power, it really flies in the top end. I am getting a Audi 5 cylinder for the 924, that make 260 lbft at 1950 rpm, so I already have a car with low end grunt.

My plans for a Fiero are a 3400TDC with the F355 front facia, but only the front facia. I don't quite know what I'm going to do for brakes yet, or the suspension for that matter.

I have an interesting project going on, and it kinda ties in closely with some of yours. I was looking at different heads that with some machine work could fit on a 2.5, like a quad four head. I was also looking to pimp out the iron duke in my 84 se, but I didn't want to go head on into it like alot of others had, and waste money. I caught my father looking the other way and ripped off his mercruiser engine out of his boat, ok, so he gavee it to me. I know it's a 153, and not a 151, but the block is very similar, and it's rated for 120 hp without a single performance part. I have a few things I am going to do to it before I install it, mainly a few valvetrain mods, swapping pistons and connecting rods, to handle thee turbo from a 6.5l diesel I got for it. I'm just sick of the Honda guys being the only ones running big turbos. I have future pans for a wet nitrous setup, but not untill I get the turbo dialed in. Keep the messagees coming, guys, it's good to hear from others trying to build up 4cyl performance in fieros, not taking the easy way out and bolting in a 350.

Check out V-8 Archies, He installs small block Chevy V-8s for about $3000 or less depending on what you want.

I would suggest Nitrous Kit or a MPFI swap if I remember right my 84 fiero had a TBI setup and those dont work as well when running a turbo or super charger set up. A good turbo kit could be made for under a 1 grand using junkyard setups (dont expect it to be perfect). My question is where would the intercooler go on a fiero? For cheap 4 banger ohv speed Id just suggest some sort of nitrous set up. Best bet would be to find a DOHC 4cyl that will fit in for cheap. Im all about handling and good gas mileage thats why I own a CRX. From my expierience my fiero understeered really bad. For suspension what are you running? Id suggest if they make it for your car some H&R springs and Koni adjustable struts. What brakes? Brembo??? Just curious cause could never find much aftermarket parts for my old fiero.
