Though it will be some time before this project is really put on to the fast track, we were able to get some development done on it while we wait for the remaining suspension parts to the 5/6 Speed Project. For those of you just joining us, the 3.4 Twin Cam Turbo in Chris West's 86 SE (Fast Red) is going on to greener pastures and it will be time to fill the gap and raise the bar on the west coast.
In its place will be a 4.0 Aurora V8 Turbo with a 6 speed transaxle. Development on the tranny is being done on another thread and though this thread will most likely be dormant until we finish the 5 speed for the current customer, we already have some pictures of the V8 and the turbo we'd like to share. Enjoy!

With the intake torn down. The starter can easily be seen.

Coming up: Mr. Turbo

Kinda a off topic question, but why was the choice of the 4.oL chosen instead of say the N* or something with more displacement? When I was @ the yard the other day, there were N*'s there, as well as the 4.oL DOHC motors, and I really didn’t notice the difference in the size of the motors.

I will admit that I didn’t walk out there w/ a tape measure, so I may be off a little, but they are both wide motors being that they are DOHC. If you are going to STUFF something into a Fiero w/ a turbo on it, that is that large already, why not see what that new trans will be able to handle?

Also, is not the support for other engines going to be easier, being that there is an aftermarket arena for said engine choices?

Either way, I'd LOVE to grab the "OH CRAP" handle when that turbo spools and look forward to the build thread.

------------------

I am curious what year is that aurora? 2000 - 2004? The aurora and the N* are the same outside diminsions as far as I can tell. It will be interesting to see how you manage to fit that combo between the frame rails.

I think they went with the Aurora to be different, and because they had the complete engine sitting there waiting to be used, IIRC.

I wonder if Chris will let me drive this one too when its done?

SWEET!!! Up for making a second set of mounts while your at it?? Heck how about an 87 cradle for a 4.0??? LOL! My poor motor is just waiting for me to get it installed.. But I have NO clue what to do... Sigh..

To answer your question mcaanda, this Aurora engine has been sitting in the shop waiting for a home for some time. We know that there are 18 miles total on it (its either a 2000 or 01 I'll have to find the paperwork) making it a prime candidate for a conversion. There will be little need for aftermarket as we intend to fabricate most if not all of what we will need just as we have in the past.
Currently, the stock intake looks like it will be replaced with a fabricated intake and the use of carbon fiber is likely.

Before the pictures of the turbos, a picture of the flywheel now making its home on the Aurora as well as the adaptor plate for the 6 speed.

The Turbo sitting next to a turbo similar to the one on Chris' current turbo on the 3.4 Twin Cam.

Ball bearings. The ID plate didn't come out well but it reads:

Type: T3
Part Number Super T70

Comparison of the exhaust side.

That turbo looks appropriate for go fast.

even that T3 looks like a pretty nice turbo for a 3.4 Pushrod or a 2.8. The ex housing is alittle small for anything bigger then that. Is it a T3 super 70 or a hybrid T3-T4?

It is a hybid t3/t4 .63/.60...

too bad no icon for jeez'ms...lol!!

Guys just wait...I think this will potentially be a high mark for the WC...as USUAL!!

Thanks nocutt, I almost forgot you were there when I was taking pictures laughing at how it looked like it could suck in the other turbo....

that lil one looks very familiar

------------------

still plays with cars..

The Aurora is a Northstar with slightly smaller pistons, same intake cams as 275 N*, smaller intake valves and a few other minor differences. It's rated at 250 hp vs 275 or 300 for the N*. Almost all parts interchange. Looks like a good project start there. Suggest you pack the injectors in something before they varnish shut. You'll probably have larger injectors anyway.

tell chris, if he wants to up the HP and TQ on the 4.0L aurora by about 25 , i have heads and cams complete, from a 2000 Northstar engine, with only 16k Miles.. they've been sitting in my garage collecting dust for the past year. I have a 4.9L caddy engine going into my fiero, and i bought the Northstar longblock from a junkyard, to get the larger, higher compression pistons out of it. It came off a freshly rear ended Seville STS. I'll sell them to him for $120 plus shipping. I live in FL, but UPS ground is fairly reasonable these days.. if he wants them, you guys can paypal me or money order me the $120, and schedule a UPS pickup. If you are interested, email me at aaronrus@earthlink.net and i'll email you pictures of the heads and the cams. I'll also consider trade offers if you have something that i'm interested in.

LOL....

Remember that the Aurora has a smaller bore... Not sure how well the larger N* valves will work in it...

Well now, sounds like a winner to me.
Looks like I need to clear out some of the old corners of my own garage, and see what I can conger up.

I actually like the thought of getting something out there that is not the "Norm."
I know here in the local area, there is a lot of development that is coming out of the Fiero world, as Ricks got the S*, the F-Body PS, and now the 4.oL Turbo by WCF. Forget the turbo part of it, I think that there is only one other 4.oL that I have heard of going into the Fiero, and then there is the addition of a FI option….just sounds like a lot of fun all the way around. Makes me want to get out there and take care of that harness that my SSEiGT needs…
Lots to see and dream about lately. Keep up the good work and remember to charge those digi cam batteries

The use of the SPEC aluminum flywheel was deemed unnecessary for the drivability and performance of the Aurora Turbo.

No kidding...
I was wondering exactly why it was deemed unecessary...

Personal choice based on past experience with aluminum flywheels. He doesn't like the way aluminum flywheels affect daily driving.

Ahh... thank you.

Hi all,

Will you need to cut into the trunk to fit the turbo???

quote Originally posted by pavo_roddy: Hi all, Will you need to cut into the trunk to fit the turbo???

my guess is probbaly, but depends.. ive seen N* installs without cutting the truck for a turbo.. so it depends on what they want to do

Considering they are going to run boost, the better flowing heads might be a good idea, but also considering they are going to run boost, they are probably not needed :-)

Hi all,

You got any pics of those North star turbos??? Assuming they are in a fiero...Sorry, for the flame I've seen N*'s in a fiero and there just doesn't look like there is room for a turbo other than the trunk area.....

i was looking at my 88 coupe with the aurora and 5speed isuzu sitting in it. because the 5 speed is so small it looks like you could run a turbo on the drivers side. it would be tight of course but what isn't in a fiero?

Hi all,

Anything new on this??

Unfortunately not at this time.

Project Aurora Turbo will be completed after the 5/6 Speed Transaxle is completed.

***Bump***

HI all,

This has been languishing too long.......WE NEED updates....Are there any???
