Well, it has been over a year when I finished my TPI build in my red car so I needed another winter project. That car had a nice Grooms 3.4 engine with many mods that was putting around 146rwHP/190rwTQ so it needed a new home. What better patient than my stock 2.8 yellow car! This car I bought it back around 2001 as a white Formula. I was going to convert it to a GT but after seeing it as an SE I fell in love with that shape and that way it stayed. Main difference is that it has round trims as an 88 SE would have I guess. It has a totally stock 2.8 with a NX kit.
The plan is to add some proven performance upgrades to the 3.4 and see how it responds. It is not my intent to document a full 3.4 swap. The True Point Four name comes because I will use the Trueleo intake, which seems to be the hottest item around for 2.8-3.4 cars. After all mods I will dyno the car and show here the results, as I always like to bring real factual data and no talk The original output of that engine was mainly a result of these mods:
- Ported TB and intake (last I used was J. Striker's proto)
- Custom CAI
- Under drive pulley
- FOCOA headers
- No cat
- Borla exhaust
- Jacobs ignition computer and wires with NGK UR5 plugs and Accel coil
- Wester's custom PROM
- Minor porting of middle and lower manifolds

Cam and rockers were stock 3.4, heads were stock, regular timing chain, exhaust pipe diameter was stock and tranny for the dyno pull was a 5 speed Getrag. The mods that I will add on top of that are;
- Trueleo intake
- H272 cam and valve train
- Shaved heads
- 2.5" exhaust from down pipe to single entry/exit Magnaflow muffler
- 1.52 roller tip rockers
- Roller timing chain
- PROM tuning with WBO2

Tranny will be stock automatic. I hope I can bump up some ponies with that and have more fun with it. Also this car will keep the wet nitrous kit that I will add on top of that for track use. Ok, enough talk. Here is the subject to be operated;

The subject to be extirpated;

And my operating room ready for it

This is the 3.4 as it came out of the other car. Just like any other ugly and dirty Fiero engine..

And this is the center piece of all

Looks kinda like a big 'ol Anteater !!! LOL. Just joking. Waiting for more pictures.

Alex , was wondering how big of a shot of nitrous your using? Have you used it and results? Any track times? It should run pretty good when you get done. Good luck

With a Trueleo/3.4 swap.
You're also doing a lot of the same mods that I have planned for mine, when I do the 5 speed.

I am so watching this thread.

Best of luck!

Thanks. Have many pics pending. Today I had our local Fiero club members at home (8) so I didn't have more time. More to come tomorrow

Lilchief; I ran a 75hp shot on it. Don't have track times but 0-60 in a G-Tech dropped from 8.5s to 6.3s.

I love your 2 cars, simply amazing, the yellow notchy is definetley on my top 3 list for notchbacks, Good Job! One question I had though is which plenum is that on the 3.4 motor, looks cool, post more pics of it if possible.

Thanks

This car has always been one of my favorites ! It looks good in the pics, but sooooooo much better in person.

Can't wait to watch the progress on this one !

Hey Alex i know you like both of your cars, but do you have a preference for one or the other ??

Let me continue. olaf_fiero27; That's the Trueleo intake. Tony, I have no major preference. I like the color and sleekness of the yellow plust it easy to use automatic and the simplicity of the red with the big rumble and 5 speed to shift. Here are some more pictures of the intake. This thing is a work of art...

I cannot forget about my #1 fan

I powder coated some parts. These are the valve covers after coming from the hot tank and being masked;

And these is how they came out after some cooking;

Sorry, I meant the intake manifold that is on the 3.4 when it is on your garage floor, not the truleo one.

Oh that one. Look at the history of that one on these;

So my engine is back from the machine shop. Sent it there to shave the heads, clean up the valves and assemble the cam, chain and valvetrain as I didn't want to mess with that at this time. Hopefully this weekend I can drop my old engine and swap parts.

Yeah the gasket was taken care off...
Roller tip rockers (1.53)

and roller chain;

Curious why you powdercoated the middle intake plenum when you've got a Trueleo...?

Looks great Alex. I would start with a 35hp shot of N20 and even go with a richer fuel jet just to see where your A/F is on the wideband before going with the full 75hp shot, especially since the new intake flows so much better at higher rpm.........Paul

Be careful with the 272 cam and shaved heads, i hear that it starts getting real close to the valves hitting the pistons.

also, i hope you didnt use 1.6 rockers, cause im told with that cam and those rockers it WILL hit the head.

i may not know what im talking about, but thats just what i heard from other posts.

if those are 1.52 rockers, im sure this motor will be a beast, one horse of a 3.4L motor.

matthew

Fastback 86; When I powder coated those I wasn't sure I was going to buy it at this time but I just did. That will be for sale soon.

Paul Prince; I'll have an Inovative WB hooked up to it. A 35hp shot is nothing. I did it in the 2.8 and couldn't even feel it. On the fuel jet I'll be cautious and go bigger and then tune it down.

m0sh_man; The machine shop took care to measure everything. The lower intake needed to be shaved too. And the rockers are not the 1.6

Couldn't drop my engine this weekend. I wonder why... But here is the powder coated intake. What a difference. Should I put a "Fiero" label on top? Any other idea?

Looks like it's coming along nicely...

Did you contemplate grinding down the welds on the intake before powdercoating?

Always impressed with your work man!! Keep it up.

Are you doing the powder coating yourself ??

If so, good job.

Did you keep the stock valve springs? Pushrods?
Did you have any head porting done? Gasket matching?

Looking good!

quote Originally posted by Scott-Wa: Did you contemplate grinding down the welds on the intake before powdercoating?

I did but I was lazy and let it that way. Also didn't want to compromise the strenght of them

Thanks Amir. Your cars are awesome too. I guess we are in the same waveband

quote Originally posted by exoticse: Are you doing the powder coating yourself ??

Yes. Harbor Freight gun and oven with Pendry powder. Very easy and works great.

quote Originally posted by Raydar: Did you keep the stock valve springs? Pushrods? Did you have any head porting done? Gasket matching? Looking good!

No. I upgraded both of them. No head porting. Only shaved. Intakes are gasket matched.

You could have coated it gray and made some kind of wierd Star Wars walker out of it.

LOL! It really looks weird at some angles. I bet Monster Garage could make a wild SciFi motive car with it

Tranny was freshened up. I was going to paint it black but I think this will match better with the other silver brackets.

Before..

After

So here are some steps re-assembling the engine...

Tming chain;

Water pump & balancer;

Pulleys, intake and valve covers

Looks Badass with those headers and the intake. the tubular look will never get old.

YOWZA!
That looks great.

looks pretty good - look forward to seeing a dyno

the mysterious 12 legged octopus... wait.... that doesnt make sense

Very nice. The intake and headers should really wake the engine up.

Edit to add

If you plan on running nitrous, I recomend using a dry shot only. If you use a wet shot before the TB like you did on your previous engine on this one there could be trouble. Looks like the intake is prone to have fuel puddle in the upper section. You could have a nitrous backfire and a significant explosion.

If you want to run a wet shot, go multiport in the intake runners. Only way to ensure you don't encounter a nitrous backfire.

This is a nitrous backfire, not pretty.
Some bad language so might not be work safe

Wow! What a video! Why they took so long to use that fire extinguisher?? I was expecting the import to blow up and was the Z06! That was a very bad tune man. To be honest I'm a little worry about those velocity stacks inside and the effect they may have with the wet kit. Will see later on how I handle it.

[This message has been edited by Alex4mula (edited 01-06-2006).]

The nitrous backfire really has nothing to do with the tune. The intake manifold was full of nitrous and fuel, some combustion gasses could get passed an intake valve and boom.

I want to run a multiport nitrous system on my N*, going to put the injectors as close to the intake valves as possible. My N* intake would also be prone to have fuel puddle in the lower part of the intake, and the fact its a composite intake makes it even worse if I had a backfire.

N*s intake is similar to an LS1, air enters the bottom of the intake and goes 270* around the top of the intake to the head. A single fogger in front of the TB would be a bad idea, fuel would puddle in the bottom of the intake.

I'll get out of your thread now

quote Originally posted by crzyone: The nitrous backfire really has nothing to do with the tune. ...

I would not bet on that. Many people are using different setups of nitrous succesfully on LSx engines. But some get crazy and don't do their homework. I don't disagree that the intake may be prone to that but each case like that must have a root cause. Now those plastic intakes are bad for backfires. There is a new aluminum LSx intake and one of the selling points is that. Too bad there is none for N* market.

MRJ has a intake that doesnt have velocity stacks in it, maybe you could trade him.

matthew

Is there any way you could post a clearer pic of the velocity stacks inside? I can't really see anything in that pic you posted
