ok so i have a couple questions...... please help

mattern248 · Post by **mattern248** » Fri Nov 21, 2008 10:05 pm

ok so i am about to buy a spare motor for 200 bucks and i am going to build the hell out of it so heres my questions, so i am going with the srt turbo setup for now i have the stock turbo and mani stock waste gatet and mopar bov but i will be getting the hks ssq bov now i will be boosting a minimum of 15 psi and all stock srt-4 parts even intercooler just because i don't rally want to spend thousands on that my questions are,

to go 15 psi i will be needing get a better waste gate or not??

i want a extremly realiable motor so i will be doing everything i can to make it this way so there comes in the ignition part
can i use all of thee in conjuction with each other and if so do i need all of them to make great numbers and to be reliable
AEM Fuel/Ignition Controller
MSD Ignition System (DIS-2)
MSD Tach Adapter
MSD Coil Wiring Harness

now for the fuels situation i have already ordered a walbro pump and i might be getting an agp return fuel line but what size injectors should i run stock srt-4 or bigger?

and so i don't just start another thread i have a question about the drivtrain, i know that you can use srt cluches in the t-350, but what about the axles?? i want to get these DSS Axles for the srt 4 so any and all info is greatly appreciated and so you all know i am building the spare motor with everything and i will be getting the valves done so i cab get 1mm over sized ones but i read some were that the dohc were 2mm bigger then the stock sohc's valves so the 1mm bigger dohc are a total of 3mm bigger then mine. can i make then that big????? ok start answering

ok so first are you talking about building a 2.0 neon motor. well there really arent alot of peolpe who are doing that as you wont get the results u are probably wanting. like if you read on the srt-4 swap section then u know what im talking about.but in reality its like u can do a whole lots to a 2.0 motor and probably still never be faster than a stock srt-4. and if i remember correctly a 2.0 neon can only run like 7psi with stock internals but if upgraded i still doubt it can run at 15 even. but just try to read around on lots of forums cause since most people havent built a 2.0 motor i doubt there wilkl be lots of responds.

haha... That's funny. Gunmetal's motor that I (and he) built is on it's way to 500hp. Mine's on it's way to about 675. Both 2.0l motors. My last setup was reliable up to 28psi when the stock intake manifold popped. The motor was plenty sturdy though. Len Ayala ran 9.27 in the Hahn 2.0l.
My stock motor ran 12.682 ET at around 10psi. Find me a stock SRT doing that.

ok well what i was trying to say i guess is u have to spend more on a 2.0 motor to make it run at that power than say just fixing up a 2.4 turbo engine.

but its cool i mean he can do that if he has the money but i guess i would just rather fix up a 2.4 engine than a 2.0.

I hear what everyone's trying to say.

The 2.4 will make more power in the long run as you start with more displacement, power, and a better aftermarket selection.

The 2.0 you have to spend a little more money as it is a smaller less powerful engine and to get to the stock srt-4 power levels you have to first invest a bit of money.

You're talking about "building the hell" out of this engine. If this is the case, sit down before you do anything and figure out what you want the end result to be. 15 psi of boost eh? Do you want to spray? if so, how big a shot? You may want to lower the compression to be on the safe side.

I would recommend forged internals if you want it to be reliable. If you live somewhere where it is cold however, it will be scary when you start your car if you haven't run it for... a day or two and suddenly it sounds as if you have piston slap. Forged pistons expand when hot, and contract when cold. Just be gentle when it's cold.

Since the 2.0 has less stroke, it has a higher redline, not that it is as important with FI. The power can be made at a lower rpm, but it is an option. Of course there is the 2.2 stroker option, which will help narrow the displacement gap. The 2.0/t-350 also weighs a bit less, also helping the power to weight ratio. And handling, as there will be less weight on the steering tires than with a full SRT-4 set up. So there are more things to consider than the intial advantage of the 2.4

The aftermarket alone justifies the 2.4L over a 2.0.

However, if you're going to build it up and don't mind spending the cash...when who cares. Good luck with it and try not to blow too much money.

I personally think it'll be 10x easier to just build up the 2.0 then dealing with the shit of a swap.

250-300 horses is enough regardless of being on a 2.0 or SRT-4

Of course OP never mentioned that he was using a 2.0 or 2.4
From what I can tell he is eluding to using a 2.4 DOHC/ SRT clutch on the T-350 MTX. But since the 2.0 started getting ripped on I figured I would point out the few advantages it does have.

As far as stock valve sizes I thought/think they are all the same diameter. I haven't read anything on the DOHC valves being larger.
I'm not sure how large the center spacing/seat area will accomodate.

Here is how it breaks down...

SRT-4
Head Diameter - Intake 34.67 - 34.93 mm 1.364 - 1.375 in.
Head Diameter - Exhaust 28.32 - 28.52 mm 1.114 - 1.122 in.

2.0
Head Diameter-Intake 32.12-33.37 mm 1.303-1.313 in.
Head Diameter-Exhaust 28.57-28.83 mm 1.124-1.135 in.

Yep, the 2.4 has a valve size advantage on the intake side, the 2.0 on the exhaust side.

MP sells oversized vales for the 2.0...34.00mm for the intake, 29.30 for the exhaust.

Sweet! Is that for all DOHC heads, or just the 2.4 or SRT 2.4?

Danteneon · Post by **Danteneon** » Sat Nov 22, 2008 3:52 pm

Should be for all 2.4s. The bare head part # on a SRT is the same # for all non SRT 2.4s (after 2001, and the 2004 2.0 DOHC Stratus) so the valves should also be the same.

Why are you going to use the MSD ignition and the AEM controller?

mattern248 · Post by **mattern248** » Sat Nov 22, 2008 7:54 pm

well wow i didn't know so many were prone to swap i like my little motor lol i will be building the entire motor that inckudes rods and piston i was planning and droping the compression a little also and there is a very good shop a few miles from my place that does great port and polish work. now to answer questions

i was planning on spraying but i don't want to over do it with it( never used it before so i might do a very little bit at first till i get enough knowlegde about the stuff,
and i live in az so the cold isn't a problem plus the garage is heated.
i was thinking about the 2.2 stroker but i don't know were to start to get that off the ground.

money is not a problem it when it comes to this build i may not have it all at once r anywere close but i will make a steady approach towards my goal, remember it's a spare motor i am builing so i will still have a dd
so Danteneon would i be able to use the 1mm bigger valves for the 2.4 in the 2.0 with enough head work???
]and for th msd and aem i didn't know they were basiclally the same. and can i run the aem controller on the ngc????

INVUJerry · Post by **INVUJerry** » Sat Nov 22, 2008 8:02 pm

Well, I think you can run the AEM controller on an NGC, don't hold me to that though. Are you doing a 2.0 or a 2.4? Modern has the 2.0 valves that you need. Are you boosting, spraying, or both? If you're boosting with the srt turbo, to get to 15PSI, you'll need a wastegate controller, like teh AGP, it's only $160 or so.

yes i am using the 2.0 motor it doesn't have as much power to begin with but by the time i a done building it it will i am shooting for 350 hp but i might go further then that and i did want to know if i needec the agp thin so cool thanks. i will be spraying and boosting. thanks occasional demons for the links i will be reading them in a minute

Just make sure you have plenty of meth...

what do you mean?? like methenol injection??? i actually already ordered one lol

Adionik · Post by **Adionik** » Sun Nov 23, 2008 1:49 am

Yeah...you ordered a kit or what? I'm probably going to piece together one and tap into my washerfluid resovoir.

IMO, you can't have enough protection like that. I could care less about making huge HP until my engine is running COLD and solid.

yep i ordered one already i started to make my own but kinda forgot about it when i moved.
