what internals for 2.3l stroker?

[jayiszraw]

so i was wondering what internals would make a decent 2.3l stroker also since i will be replacing the crank and all bearings will that eliminate the chance of crankwalk on a 7bolt? would i be better off stroking a 6bolt? i have done some searching but it gets a bit confusing. would i be best off just buying a stroker kit or the internals seperately? any input would be appreciated

To build a stroker you need a 2.4 block.
What type of power are you going for?
Also are you going to be doing autocross or 1/4 mile?
E85, pump, or race fuel?
And there are a bunch of other questions that will determine what exactly you need. I personally bought a stroker kit from slowboy and am very pleased with what I got.

NO! You do NOT need a 2.4 block! A 2.3 is built using a 2.4 crank with special pistons.(and I think rods too) Just build it with a 2.0 block 6 bolt or 7 bolt your choice. Buy a stroker rod and piston kit and then find a good 2.4 crank. Most guys use Eagle rods and Weisco pistons. This combo typically handles 500+ hp.

would it be possible to use a aftermarket forged crank? 100mm?

 

[tenn-gsx]

Yes Eagle makes them as well as some other venders. The thing is that unless your going for huge numbers its not really needed to use an aftermarket crank that will cost you $700+ when you can get a good stock crank for a couple hundred or less.

 

[stroked_AWD]

You can use a stock 2.4 liter crank from a spyder in a 7 bolt block and that will make it a stroker. I went with wisco pistons and eagle rods and it worked out for me pretty good.

 

[jayiszraw]

is it true i have to buy shorter rods or something like that? or the typical 7-bolt eagle rods are fine?

 

[tenn-gsx]

I believe they are special rods. If you shop arround you can get a stroker kit which includes the pistons rings rods and maby the bearings for arround $700. The kit that includes the forged crank is arround $1500.

 

[jayiszraw]

as for the bore on the pstions? what bore would be good? .020 over, .040 over? which compression is better 8.3:1 or 9:1 i know lower comp theres less chance of detonation but higher comp is more power on less boost?

Rods for the 2.3L stroker are the same length as stock 2.0L and 2.4L.

Caution, caution, this thread has a high level of disinformation for so few posts.

If you want to learn about the differences between the 2.0L and 2.3L versions of the 4G63 please read http://www.kidzuku.com/StrokeOrNot.pdf. If you don't want to learn more, a lot more, then the best choice is to buy a complete stroker kit.

 

[tenn-gsx]

I stated both times that I THINK the rods were special. However I was sure about the pistons and crank. And I am also sure about the rough pricing on the components if you buy them in a package.

The only stated mis info is needing a 2.4 block.

Maby I should have said I was not sure but I THINK they are different.

You just need a longer stroke crankshaft (most use 100mm stroke) and stroker pistons to stroke our engine. You use the same length rods. If you want, I have a complete build list for a 6 bolt stroker engine swap into a 2G I can send you.

 

[Wicked_Sick]

Blazebolt, mind sending me that list? Thanks.

 

[blazebolt]

If anyone is interested in my build list, PM me with your email address and I'll send you the excel file.

Sorry for me being incorrect. I had to have a 2.4 block to build my 2.1 de stroker just figured that if you had the longer stroke crank you needed the extra deck height. My mistake.

 

[jayiszraw]

would i be better off with a 8.3:1 compression or a 9:1 compression? will the bore effect my build much? .020? .040?

 

[nkosi]

Heres a good shop for a good price stroker kit ...i deal with theses guys and their stroker kits are top ...here the link https://www.jacksonautomachine.com/html/shopping/list_section.cfm?sectionId=27 take a look

 

[woooop]

I love how people just add ther 2 cents when thay dont know shit ! Use the search botton it works wonders.

 

[Ahsieh2]

Here's a very interesting website I found that sells crankshafts. 88mm and 100mm stroke. Worth a peek especially for $450. I would buy one if I hadn't just bought an Eagle crank.
Weightless Crankshaft

Ok, first off for compression you think about it. If you go to the higher 9:1 compression you can have more power in the low where you dont have boost, and maybe in the higher and a faster spooling turbo, but a higher chance of knock. If you go 8.3:1 you might make a little less power but you can make up for it by turning up the boost and make even more power, but because you can turn up the boost and have less of a chance of seeing knock... you might also have a slower spooling turbo.

Second for the stroker. There are many ways you can do this. You can do a full on 2.4 block swap but technically this isnt a stroker. You can also keep the 2.0 block and swap in the 2.4 crank and to build get some STANDARD rods, but you have to get STROKER pistons(which move wrist pin location). There are other strokers for the 2.0 but the 2.4 in a 2.0(2.3) is the most common. Another popular option is the 2.4 de-stroker where it uses the 2.0 crank in a 2.4 block but whats needed is longer rods(which alows to rev higher).

Last all this info could have been found by a click on the search button.

ok im building a 2.4 stroker for my 91 talon and im using a 6 bolt j14 block with a 6 bolt 2.4 liter crank from a galant then you use any chioce of rods that you want and stroker pistons....the wrist pin is higher on the stroker pistons...and that is the basics of a stroker motor.

 

[DSMified92]

and for your compression question 8.3 you can use alot of boost with the right tune and fuel....thats what im doing cause i love boost and the pssssss ...and 9.1 you will have alot more low end but can not use as much boost as the 8.3.......to simplify factory turbo motor is 8.3 factory n/t is 9.1

 

[jayiszraw]

thanks guys that makes much more sense now, i did lots of searching but i couldnt find anything as simply put as what was said.

 

[blazebolt]

There are a lot of threads out there regarding piston compression ratio. In short, if you want to run high boost go with lower compression. If you want lowend torque, you go with higher compression pistons, but you can't boost as high. Higher compression pistons are harder to tune for as you will need to reduce timing a lot. Also, remember the higher final compression ratio you have, the higher octane fuel (or use meth/alchy/water injecton) you will need to keep knock down.

Final Compression Ratio = (Boost/14.7+1)*PistonCR

Thanks for posting info like this, its very helpful
