Y'a plein de bon monde qui vont pouvoir t'enligner dans la bonne direction.

Malgré que 2gn.org est dur à battre pour les infos.

No you don't need to change the crankshaft. But to change the piston/rod assemblies, the crank should be removed, so the bores can be honed, or the engine removed, to take it to a shop to bore it.

It could be honed with the crank in, but getting it cleaned properly afterwards may be difficult. You don't want the honing grit to get into the oil passages in the crank jounals. Also the journals on the crank should be inspected, to ensure the new bearings will last.

As long as the bores do not have a lot of ridge at the top, the pistons will slide out the top relatively easy. If they won't due to the rings hitting the ridge, a ridge remover would be needed to keep from damaging the pistons/rings, possibly gouging the upper bore.

can i just take all out just by the bottom(oil pan) without remove all engine or head...

i search for some piston,conectin rod , what is the place to buy that can i use srtr4 piston rods or pt cruiser srt4 ...
thankss

ps maggot jme suis incrit sur club neon thanks vieu !

nope. the rods won't come out the bottom... only thing you're gonna get is the rod caps.

Also, if you're looking for a "how to" to remove pistons.... this might indicate it's more than you can do yourself.

modernperformance.com sells forged engine rebuild kits, you cant use 2.4 srt, pt internals, only 2.0 internals.

Yes! It does not come out the bottom!

You can't use SRT-4/PT/2.4 pistons or rods in a 2.0 SOHC. Well, you can but it won't actually turn over and run.

thanks that pict say everything !there in pict is not the stock piston and rod!!

sohc and dohc as not the same block?? ithinck only the head as not the same

so i can't use srt clucht or pt clutch on my neon
i looking at exedi clutch they dont have any stage clutch for sohc neon i am looking for something stronger ....

Yes, that IS a STOCK 2.0 SOHC piston and rod and a Neon 2.0 block.

I like to post this picture when people claim they have changed pistons out the bottom. It's impossible to do it.

You can use a non-turbo PT Cruiser clutch but it won't hold as much boost as an SRT-4 clutch. You can use an SRT-4 clutch with a Neon T-350 transmission but ONLY if it is machined to fit the transmission. It will not fit into the trans housing if you do not machine it correctly. You also NEED to machine the back side so that the flexplate fits it.

All '96-'99 2.0 SOHC and DOHC blocks are the same.

i was 2003 sohc sx that change somenthing in that ...???

Hudson_Neon · Post by **Hudson_Neon** » Fri Sep 02, 2011 12:00 pm

nope. your best bet is either a non-turbo pt clutch or an aftermarket one of some sort. if you pull your oil pan, bed plate, and crank out, that's exactly what you'll see. you CAN change pistons with the engine in the car, you just need the bottom off like that and then take the top off too and the pistons come out the top

that part of the block did not change on the 03+ blocks, so no your pistons still wont come out the bottom

just to clarify for queboy, you only need to take the caps off the rods to remove the pistons and rods out the top, you dont need to remove the bedplate and crank to do that job.

sidepipe, you need to relax.

I looked at how tos and what not before I pulled my motor to rebuild it. It can't hurt to find out any tips from those who have done it before.

true, my bad for not explaining the difference... you don't even need to take the crank shaft out to pull the pistons out the top. that's just what is shown in that pic. when i did my high compression build i didn't take out the block. when i did my low compression build i did and it was a little more work at first, but far easier to do the build itself.

ok great !
how many time i could expect to spend on that jobs

i thinck i will look for a use block and rebuild it slowly

so long as the bores are clean and not scared up i'd say an evening is all you need to swap out pistons really. just make sure whatever you use is standard bore and not overbore or you are going to run into issues.

sorry but are you mean oversize piston ?

Post by **occasional demons** » Fri Sep 02, 2011 2:26 pm

Yes.

But with new pistons/rings, the bores should be at minimum de glazed, or honed to give the new rings something to re seat them. Otherwise they may not seat/seal well.

quebboy · Post by **quebboy** » Sat Sep 03, 2011 11:14 am

i cant use oversize but what about compresion ??

and what is deferance here with my stock -5cc or find +5 cc
Dodge Neon 2.0L SOHC/DOHC - 87.5mm Bore, Std Sizes,**( -5cc Dish, )**8.8 Comp Ratio

Dodge Neon 2.0L SOHC/DOHC - 87.5mm Bore, Std Size, +5cc Dish, 10.5 Comp Ratio

This is what you want with boost.

quebboy · Post by **quebboy** » Sat Sep 03, 2011 11:48 am

so i assume that lower the compression ! but what mean +5 or -5 cc
sorry !

and i look at wiseco but i love the find pakage with good price ....

can you guide where i suposse to look for that part

Hudson_Neon · Post by **Hudson_Neon** » Sat Sep 03, 2011 12:30 pm

we have 2.0L engines. that's 2000 cubic centimeters (cc). well actually they're a tiny bit less i think, but it's close to 2000. so for example sake, +5cc would make it 2005cc and -5cc would make it 1995cc. it's all the displacement of the engine. i'm not sure if you can find wiseco packages anywhere. sorry

The +/- is the size (cc) of the dome or the dish based on Wiseco's measurements changed from a flat top.

You can't change the displacement of this engine by changing the shape or size of the dome/dish. Displacement is bore x stroke x # of holes.
