Europeen style 3800 turbo swap - what do you think ? (Page 12/14)

What a nice build. I hope you get it up and working again.

It is working!
My car doesn't stay dormant very long, if it can be helped.
Will be going to an end of year cars-n-coffee on Sunday 29th December.

I would like to put 235/60s on the rear to fill out the wheel well a little better, but it's hard to find 15 inch track day tyres in 60 section?
Yoko used to make some but I haven't seen them in ages (available in Europe). I might cough up the import taxes one day and order Mickey Thomson drag radials for the rear….
...one day!

Pour La Fiera: pas de problème. Je suis content que ça t'avait plu!



Je l'aime!

That's tha the same tires I have on my Fiero! Bon travail!

Keep the 50's, if you get 60's the car will have a delay when you turn.

Hello everyone,
Just got back from the "contrôle technique" (inspection, MOT etc...) with a clean bill of health for the Fiero.
Photo as we picked up the car:



For those who are interested, my weights and brake readings from today:


And the same from 2 years ago, before the "Seville" rear brake upgrade:


Even though the front brakes are a little uneven (probably pads), my overall braking effeciency is up 13%! Which is good for balancing the car in harsh track conditions.
We can see that the battery relocation took 5kg off the rear also.

Anyway, enough said. I'm just happy that the Fiero passed with no problems!
For those who want to see just an ordinary day out for the Fiero, here's a link to last weeks cars-n-coffee meet up:

Best regards,

Hello....I have two questions; 1) What do people over there think of the Fiero? And 2) Which way is that deck-lid fan blowing? Up/out or down/in...?

Your car is sharp and has impressive performance...I like the color, too!

Mostly, they don't even know the Fiero. It's often called out as a gen 3 Firebird off all things!
The papers above for the "contrôle technique" state '87 Pontiac Firebird, because there isn't anything else in the data base !!

Young kids seem to like the car, but once their parents know it's a Fiero, then it's just bad comments on under powered Lambo/Fierri replicas. Only when I'm on track do I get a little, albeit begrudging respect.

For the fan, it's up-n-out. Same as the intercooler/oil cooler fan. I try to draw the air in from underneath.

Thanks for the last comment and the colour is a two tone Maserati metalic green.

Regards,
Rafe

I don't like emissions tests, but the 3.5% CO limit is pretty generous.

I wanted to say; I have for years wanted to get someone with money (Obviously not me) to build a Fiero with an LS4/400 hp and some suspension tuning to lap a couple of tracks and lay some really good times down......I also thought of adding a vacuum system; Two fans positioned under the deck vents that would only come on during braking and cornering, shutting down on the straights, run by AGM batteries that would be recharged on the straights......A Modern take on the Chaparral vacuum car....

My fans are just for air circulation/cooling.
I believe Chaperelle cars used a second engine to turn those turbines. (No longer just fans.)
As well, look at the aero: it wouldn't resemble a Fiero anymore 😲

Regards,
Rafe

PS: My car pollutes twice as much now. It must be faster! 😉@pmbrunelle

Hi all, Happy New Year!

New "old" problem:
I took the Fiero out for a New Years Day run yesterday and after 45 minutes, it threw a code/SES and started to run rough.

I pulled over and opened the engine lid and was horrified to see my headers glowing bright red!
The body of the O2 sensor was glowing red as well.

(Sorry no pictures as I was aiming the fire extinguisher at the engine while it cooled down! This is a 3800 S2 with the turbo hung on the rear manifold by the way - for those who don't want to read all my build thread.)

Anyway, this "overheating" problem is not new and I've often had the code relating to "cam sensor" and "EST line not toggling".
I even had a fire start one day because of a split driveshaft boot spewing grease onto the manifold and turbo.

For me, these codes are just secondary symtoms and maybe the real reason is the engine is running very lean while cruising? Good thing for emmissions and fuel economy but bad thing for exhaust gas temps and turbo setup slowing the exhaust flow!
The heat builds up in the manifolds.

Anyone else with a turbo setup had the exhaust glowing cherry red?
Possible fixes?

Thanks,
Rafe
