Non turbo to turbo conversion.

[pentictontalon]

I have a 97 talon esi fwd 5 speed. Would anyone have any idea how difficult and expensive it would be to turbocharge my engine. I have a rough idea of what i need, but more need to know how much it would cost. Would you recommend just turboing the stock engine or getting an engine that has turbo and modding it. If anyone could give me some advice that would be great, cheers.

Sell it and buy a TSi/GS/GSX. ;)

Just my .02

^^ I second that.

But if you are REALLY interested in placing a turbo in your esi, you are going to need a lot of stuff..

In the long run, it will cost more money than the turbo motor because you are going to be doing modifications that the esi motor was not built for.

My .02$, go buy a turbo and mod it.

And then you wont have to consider the FWD to AWD conversion next :)

Are there still turbo kits out there for NT DSMs? I remember Doug's Dynopower developing a pretty good kit a few years ago.

I got a ride in a "turboed" 2g a few years back. The owner spent 3-4 thousand dollars in the conversion.

It was probably still slower than a turbo car with just a boost controller.

So...

+6 on the conversion idea....

IIRC or perhaps heard correctly - the Eclipse in the F&F was a NA to Turbo conversion. Ran 15's in CA. Perhaps someone knows for sure?

Hahn Racecraft sells NT conversion kits. Here's a link (http://www.hahnracecraft.com/auto/eclipse/eclipse.htm) to their Eclipse page.

"This street sleeper runs 13.70's @ over 100 MPH is the quarter on street tires! Yet it has been daily driven for over a year, from 100 degree summer days to 25 degree below zero winter madness! True real-world performance, to be sure, and aided by the fact that the RS is about 400 pounds lighter than a GSX!"

So probably high 14's here?

The green Eclipse in F&F was still a NA 420A with just a header and cat-back for sure. All that stuff they mentioned in the movie was just "fluff".

You can turbo a 2g non-turbo with either the Hahn or Star turbo kits. Slowboy also has a kit out now. You can figure about $2K-$3K to have an intercooled kit at 6-8 psi. Any more boost than that and you will have to build the bottom end with forged pistons and rods.
Others have gone the "custom" route with either a stock 1g 14B or 2g T25. It's more of a headache but cheaper in the end.
There are always turbo kits for sale plus loads of info over at 2gnt.com. We bought a Star kit plus extras but without an intercooler for $700, then found a nice intercooler for $200. That was almost everything minus piping, couplers, and clamps for just under $1K.
Having said that, I would still rather spend the money on a 4g63. We just wanted to make our non-turbo a little faster, but I still prefer our 4g63 DSMs and of course AWD.

I'm a 420a dumbass, so what's the reason you can't drop a 4G63 into a NT chassis? Are the motor mounts different? I'm sure you'd need the tranny, too.

As far as I know there were only a few successful swaps. The mounts are different, but it's a huge hassle and is cheaper to just get a GST or GSX in the long run. Besides, once you build the bottom end to hold boost on the 420A it's not much different than the GST.
Once you've gotten the 420A built for boost, then the only drawback compared to the 4g is the ECU. The 4g ECU has the aftermarket support for lots of power, where the 420A ECU will leave you dead in the water around 15 psi. But now lots of people have successfully MegaSquirted the 420A with lots of boost, so that's not much of an excuse either.
Lots of 4g guys will say that you still have the extra money spent on strengthening the bottom end on a 420A, but the 4g guys will end up doing the same down the road.
Oh yeah, there are also stroker kits for the 420A.
I'd still rather have an AWD 4g63, but the 420A is no slouch with the proper support.

Funny how the person who started this thread isn't around anymore.

Yeah, that's what I was thinking too. Oh well, maybe he'll get back around.
