Question Question on upgrades

I was looking around google for some performance parts for my moms PT Cruiser. I know theres a Stage one Which went into my dads old cruiser (That thing was A LOT of fun!). The Neon SRT-4's (the turbo Neon's) have the same engine as the 2003 Pt Cruiser GT's (which my mom has). The Neon's have stage 2, and the stage 3. Is there any way the SRT-4's turbo upgrades could be used on a Cruiser? The guy where we got the stage one doesn't know, but would like to, he has a turbo with a stage one as well, and I'm not about to plunk down 1600 + labor just to find out it won't work.

Thanks guys!

It probably should work. As you said the PT Cruiser has the same albeit slightly detuned engine. What all does the stage one add to the car?

theres about ~30 horse at the wheel hp increase, and the rev limiter is lifted a bit (it doesn't mess with the fuel pump anymore when you hit the redline). Other than that, I don't know, I never drove his car. he says its quicker, but I'm not sure about it, but I do know I'm going to put a Stage 1 in.. Have to call my friend to see if I can get a break.

Are you positive its the same exact motor? And not just the smae block? I find it hard to believe that they used the same motor thats in a "high performance" car in a grocery getter.... I can understand them sharing the same block, but not the same heads and rods/heads....

If they are identical motors, then all parts should be swapable between the two. Even things like the fly wheel, which will help alot with throttle response if you install a lighter one. The only thing that may inhibit the use of the Neon's performance parts is mounting locations... The layout is surely different under the hood of the PT and the Neon, so some parts may not fit/install without modifiction(s)...

i wouldn't be surprised if the engines are almost the same, just with more mundane parts on the pt cruiser. after all, lotus uses the same type engine found in corollas & the recently killed off celicas

You cant just bolt up any old part if the engines are "almost" the same... This is something you need to find out...

The SRT-4 used an upgraded block (A855) from the similar block used in the turbocharged Chrysler PT Cruiser. Both used the same cylinder head, however the intake manifold, turbocharger plumbing and intercooler are different. The SRT4 intercooler was a front-mounted cast aluminum 8-row unit produced by Valeo. The turbocharger was a reverse rotation Mitsubishi TD04LR-16Gk with a 6 cm² turbine inlet. Tight packaging forced some creative thinking on the turbocharger. The TD04 compressor has a compressor bypass valve built right into the compressor housing. The exhaust manifold and turbine housing were cast in one piece by Mitsubishi from high-nickel Ni-Resist steel. The one-piece design improved flow, reduced size and reduced thermal mass for quicker cat light-off. The turbine discharge was also part of the manifold/turbine housing casting, and it looped back around and hit the manifold again on its way to the catalytic converter. Where they met, there was a wastegate valve; keeping the wastegate valve away from the turbine housing improved flow where it mattered most. Maximum boost in stock form was around 14 lbf/in².

Similar engines but not the same. So some of the things that come with the stage one will work. I believe the larger injectors should be okay. Though since they have different ECUs the same flash is going to be out. The blow off valve relocator is an option so just don't get it. Basically you should probably just have a garage put in some larger injectors and reflash your ECU rather than buying the stage one kit for the SRT-4.

There is a stage one for the PT that came out from Mopar, then the idea kinda.... died (they announced the stage 2 and 3 but they never came out) Where did you find that info Malaziel? you have no Idea how long I've been looking for that stuff!

I just found this in a wiki entry on chrysler engines:

Chrysler Neon engine - In 1994, Chrysler modified the 2.2 L Chrysler K engine substantially for a 2.0 L straight-4 for the new Dodge Neon compact car. This same engine was and available in SOHC and DOHC variants, the DOHC version was later expanded to 2.4 L for use in the Cirrus/Stratus/Breeze and later used in a number of Chrysler small cars and minivans. Turbocharged variants made their way into the PT Cruiser and the Dodge SRT-4.
