automatic turbo?!?!?!

orangeneon05 · Post by **orangeneon05** » Tue Jan 05, 2010 5:03 pm

i think this is where it goes its more power done by the motor.

any way i drive a 05 srt-d automatic and i was wondering if you can turbo this car it is a 2.0L. i know i would need the metal intake manifold and the turbo parts. but i guess the big question is... is it better to just man up and get a real SRT-4 or just turbo this one.

You will want to do some searching on the site for the answers you are looking for. This topic has been covered at length.

Check the forced induction section (were this topic will be moved to) and the stickies for all of the possibilities available to you.

FWIW, I'm considering a 41TE in Grrtrude. The stock 40TE should be fine to about 300hp, I would think based on the research I've been doing.

so your car is a automatic

He said he is thinking about going to an automatic.

40TE = 4 speed electronic automatic transmission used in the 2002 model year Neons (essentially the fail of the 4 speeds)

41TE = 4 speed electronic automatic used in 2003 - 2005 Neons (much stronger and better gearing than the 40TE)

oh so its possible to turbo the automatic and he is switching the transmission out

Post by **racer12306** » Tue Jan 05, 2010 9:17 pm

Yes it's possible.

would it be a reliable DD or hella no

Isn't that the other way around? My understanding is the 41te was revised to fit the 2.0/2.4 but the gearing was not compatible with the torque of the 4 cyl's, so in '03 they went to the 40te with a different 2nd gear or some BS. I haven't found any specs that back up the gear ratio difference tho.

Digs out old FSM...

Nope they are the same gears

'04 FSM wrote:40TE AUTOMATIC TRANSAXLE
DESCRIPTION SPECIFICATION
First Gear 2.84
Second Gear 1.57
Direct Gear 1.00
Overdrive Gear 0.69
Reverse Gear 2.21

From the '04 neon FSM (40te), and the 1994 AA/AP/AJ FSM LeBaron/Shadow/Spirit (41te)

Edit: I didn't know the SRT-D had an ATX. That has to really suck. The SRT-D outweighs the SXT, and has the same out put. Allegedly the MTX's used had the 3.94 ratio to compensate. If you are going to boost, I would opt for an '02, but be warned, IIRC the electrical connector to the solenoid pack was changed. IDK if the solenoid packs are interchangeable between the older/newer ATX's A better option may be to use a GT Cruiser ATX that is '03 up.

I had seen a wiring adapter a while ago, but I have not been able to find the site since.

hmmmmmmm, guess I am very wrong.

Post by **occasional demons** » Tue Jan 05, 2010 10:04 pm

Damn Knewbeez!

Edit: Meh, I never really questioned the gearing BS till now, because it made perfect sense to optimize the 4 cyl torque with ratios better suited to the engine. If they had used taller gears in the V6 41te, it would be a perfect turbo ATX.

depends entirely on the turbo build's quality and the tune... aka go to erick. my car is turbo'd and i daily drive it.. to work, school, the bank, friends houses. of course there are things you have to work out and you might have to pull over on the highway sometimes... but once you figure it all out, it's a beautiful thing. my car hasn't had 1 problem with reliability since august.

He's the guy who posted about considering using a 41TE. Esteinmaier.

And yes you can reliably tune an automatic. My car was an auto before I did the MTX swap.

It all has to do with your setup, tune, etc. Keep expectations reasonable and there is no reason you can't have a quite reliable daily driver.

Post by **occasional demons** » Wed Jan 06, 2010 9:44 am

What I'm wondering, is if the internals from a 41te will go into a 40te. Much like the big block internals for the 727 TF would go into the small block 727. Same for the V8 904 TF into the slant six 904.

If so, a Dynasty A604 could be sourced for the hard parts, put new wear items in, and you would have a relatively reliable "40te"

how hard was the MTX swap (im assuming that is a manual trans. swap) because i was thinking of doing that someday. and if i turbo the motor before would it be hard to tune the car to a MTX setup?

esteinmaier · Post by **esteinmaier** » Wed Jan 06, 2010 5:25 pm

You don't really tune the engine to the transmission, but accel enrichments are much more important in an MTX.

orangeneon05 · Post by **orangeneon05** » Wed Jan 06, 2010 5:27 pm

so i would have to change all of the fuel timing and everything that relies on the rpms of the motor? and MTX is manual trans.

yes it is an automatic but it has lots of pep and only has a CAI. atleast it accelerates faster then my friends automatic SXT she says

She just wants to make you feel good and get in your pants.

orangeneon05 · Post by **orangeneon05** » Wed Jan 06, 2010 11:36 pm

shes a senior in high school and im a second year in college and im not sure that is the case because i have known her for since i was like in 8th grade and if that is the case she has a weird way of showing it because she doesnt know cars at all.

BTW E nice turbo kit for the 2.0 motors that your selling i saved that thread just in case i decide to go that way

lmao.... dude 17 year olds are PRIMEEEE... go grab that.

hahaha we will see i told her to let me look at her car in the spring because she isnt sure if something is wrong with it or not

Post by **occasional demons** » Thu Jan 07, 2010 7:22 am

You don't need to know how cars work, to know the difference in power. If anything, it gives her a true unbiased seat of the pants feel for how it is accelerating.

Thanks for the laugh, Mr Steinmaier!

orangeneon05 · Post by **orangeneon05** » Thu Jan 07, 2010 7:26 am

yea from the way she feels her car accelerate she notices that my car accelerates faster which is good and im sure the way i drive helps too and yes that is a very needed laugh!
