2.2 Stroke kit

Post by **SquirrelOnFire** » Wed Jul 30, 2003 8:55 am

Hi, I need some advice. I wana go big , like 400 hp big with an s14 sr20 and was wondering if its a good idea to get a 2.2 stroke kit. I really don't know much about it, except that it costs like 4 grand and seems like a nice package, but what are the advantages or disadvantages of the kit. Also down the road (if i do go ahead with the sr) when is it accualy necesary or usefull to get the kit. Also this would be a drift car for me, so would I have any adantage with this kit? Sorry for the large amount of questions, but I really dont know much about the 2.2 kit and how it does in real life. Also if installed what kind of power gains could i expect?

thx for any replys

The people you need to contact are the 2.2stroker kit manufacturers. I don't think anybody will argue that JUN is at the top notch of engine tuners. Their site has an email link, so you can contact the maker of a 2.2kit direct. http://www.junauto.co.jp/produ...t/?en

A simple google search for "2.2 stroker kit" or something similar provided me with the above link to JUN auto, as well as many discussions, articles about 2.2 stroker kits.

Most people might tell you that a stroker kit is overkill.

Damn I don't know where to flame you. Either in this thread of in the laundry parts list you posted in the Tech forum. Again I ask do you even have a 240?

man, piss of and no i dont thats why im trying to learn something before i get it.

I think what he's tryin to say is that you could have learned that all off of GOOGLE, but to answer your question the stock bottom end is good to over 500rwhp so you could leave it alone for a while and be allright.

thank you thats all i wanted to know

...for now

movingviolation........I'm not trying to argue with you, but do you have any links of sr20's with 500hp that have stock bottom ends? I know that the SR is stout, but not nearly that stout. I would love to be enlightened.

I've seen Ken from Enjuku's car (he's at 480 right now but that's only limited from his crappy T3/T4) He'll be over the magic 5 number pretty soon since he just got a new GT spec toy. Phase 2 motorsports also has a 500rwhp SR on stock bottom end. The problem is none of these guys post on NICO so they are pretty much unknown around here. I think Scott from Tampa is pretty damn close as well.

I know someone who has dyno'd 409 to the ground with a stock bottom end SR20DE....as in no T. It's turbo (ofcourse), but it has stock DE internals (9.5:1 compression, no oil squirters). If 409 to the wheels is possible on a DE, there is no doubt in my mind that 500 is possible with a DET.

if you want to do 400hp, leave the bottom end stock.build the rest and save yourself some money. the motor can handle 400hp. you may want to work on the top end however. when you are done with 400hp and want to go bigger, then do bottom end. hope you got lots of money

thx for the info, i have a lot to learn

Wayne @ phase2 : 526.5 RWHP. I think he can crack 550 before the bottom end goes.

i am not doubting the durability of the SR20DET, but yeah, they can make 500whp, but for how long. I think reliability would become an issue to worry about once you have that much HP.

Post by **SmithSR** » Wed Jul 30, 2003 8:55 am

Karter, name any car that has a reliable output of 500hp. Exotics will be at the top of the list. Next will be factory performance cars for the masses(at slightly lower power numbers, like the Z06). There really is no such thing as reliability, in the daily driving sense, at 500horsepower from a 4 cylinder Engine.

If you're worried about longevity, well, this hobby isn't cheap or easy.

I agree I dont think the sr20det can handle more than 400 consistently on stock bottom... if so enlighten me as well:oface

Making power and being able to drive that power are two totally different things.

Hell, my friends mustang made 613hp on the dyno with a 12lb blower and shaved heads. (Yeah, that is technically described as MASSIVE AMOUNTS OF FUEL being dumpend into the engine to keep from detonating). Everything was great on the dyno, but when he took it out to the strip and ran it the thing looked like the 4th of July. It was pretty sweet.

With that said, I think there is a big difference between horsepower that your engine is putting out and power that you aren't worried about driving around and/or taking out to the track for a day of spirited driving.

Sorry that I didn't specify that before.

the SR20DET will hold all the power this guy wants. you don't need 500 to drift. You don't even need 300. One of the best drift vids i've seen was of a silvia with something like 240 WHP. Most normal people (no we aren't normal) think that 250 or 300 hp isn't all that mutch at the wheels. Those are the same people that think their caddy runs 12's or their rustang is putting down a legit 450 to the wheels. HP 90% of the time is grossly exagerated.

People ask how much HP i'mg going for with my swap. I tell eveyone i'll be extatic with 300 WHP and they kinda look at me funny and say "that's it"

I hate that crap especially sence they will be running 96 WHP in their civic or 230 WHP in their GT.

Anyways, about the stroker kit ......

Because the KA is an under-square engine, it has a natural tendancy to be more of a torquey low-end engine. This is great for a "driving" car (as opposed to a drag car) but, as everyone knows, it suffers in the top end. Of course you can slap a turbo on it and port the engine. Then you would have a very decent powerband because you still retain some of that low end torque, but the upper end is increased greatly.

The SR on the other hand is an even-square engine. Meaning that it's a little more rev happy. Not as rev happy as an over-square engine like a honda, but compared to the KA it definatly has some high end.

The fact that you were talking about stroking the SR really made me chuckle because it almost completely eliminates the purpose for the SR. You are making it an under-square engine, like the KA, but it's still not as large as the KA.

The SR's purpose? I chose the SR because its lighter, smoother, factory turbo, newer, and stronger. not because its "even-square"

any of the JDM stroker kits are capable of higher rpm then the stock bottom end...more displacement is great... especially if it doesnt add weight

Post by **charlotte240** » Wed Jul 30, 2003 8:55 am

Lighter - barely ....... if I remember correctly SCC did their SR swap and the car only weighed something like 20 lbs lighter.

Smoother - that's not even a valid point because that depends on how well you take care of your engine.

Factory Turbo - If (staying on point of this post) you were to go internal, then you are already going to replace everything with stronger stuff. Also, I would imagine that if you go with a stroker kit, then you are pretty hardcore about your SR and therefore you would probably already have upgraded your turbo, exhaust manifold, and just about everything else needed for a turbo kit so you would be getting it new anyways. Not to mention the fact that stroking raises the compression, making it harder to boost.

Newer - depends (although it doesn't matter too much if we are rebuilding an engine)

Stronger - Not if you are doing a performance rebuild. The only thing that will be stock is the block.

I'm not saying that a stroked engine will not have any top end. I'm just saying that it will be more low-ranged-biased.

So, yeah, I still think that stroking an SR is not in MY best interest. Don't get me wrong, I'm no knocking the SR. Hell, I've got one in my garage that I'm dropping in my RPS13 in about a month. I'm just saying that you would probably spend less money and have a higher return by doing a KA.

I may be getting a little bold with this, but it's just a thought. Please note that I'm not stating this as fact.

I have heard that they don't use the KA engine in Jpn at all. I looked, but can neither confirm nor deny that. If this is the case, then I would imagine that would be the only reason they don't use the KA in gt300 because the only difference between the KA and SR (after doing a hellacious rebuild like would be done in gt300 where the only thing left stock might be the block) is the fact that a KA is bigger, and has a more fortified block.

I was going to mention a counterpoint to this mentioning that the SR has a higher redline, but then I got to thinking about it. Of course the SR is going to have a higher redline. It's a square engine. I thought about this because I remembered reading a post of some kid asking about raising the redline on his KA and the only definative answer was to destroke it.

Like I said before, this is just a thought that I threw out there.

Post by **RobDET** » Wed Jul 30, 2003 8:55 am

anyway

he didn't ask anything about the KA...It's been a while sence someone has said "no that idea is stupid do the KA" 'cmon man.

and the SR is smoother. It has nothing to do with engine maintenence. KA well maintained = Horrible abov 5k in the NVH departmentSR well maintained = Smooth abov 5k in the NVH department

Post by **RobDET** » Wed Jul 30, 2003 8:55 am

oah and while were at it... only the B16 is over square in hondas. All the other 4 cyl's (maybe not the S2k) are under square.

Just had to look it up to be sure... and yes you could be and are wrong.

Post by **RobDET** » Wed Jul 30, 2003 8:55 am

SOOOO it follows that you don't HAVE to have an over square engine to revv. Ask the all motor honda guys... What RPM an engine makes peak hp at is all cams and intake manafold design. Stroking a sr20 isn't goign to kill it's top end at all.
