i know this isnt a new topic...but i cant decide sr or ka.  I got 222k miles on my ka right now so im gonna do a swap in less than a year anyway.  I just cant decide because of the legality of the sr swap...but then again, how many times have you been pulled over and been asked to see what you have under the hood.  Also theres emissions...will i pass if i turn off the boost, or lower it to like 1 or 2 psi?  In any case...im selling my other car right now so ill have some spare cash lying around.  I was thinking of the following mods.  Clutchmasters stage IV kit, apexi exhaust, eibach springs, new plugs and wires, intake and an erebuni shogun style body kit.  Do you think these mods would be wise (with the exception of the plugs and wires) if im going to do an sr swap?  or should i concentrate on the bigger things, like a BOV, i/c kit, clutch (already on the list) and fuel pump.  The exhaust im gonna need anyway, so thats a given.  what do you guys think?

xhdriver · 07-26-2002, 01:15 AM

uh just fyi, you cant lower boost below the stock setting, and the clutch and intake will be non transferable.

MasterOFDrift · 07-26-2002, 02:10 AM

most of the mods you just listed aren't transferable from the KA to the SR. The Sr20det will pass the sniffer so you don't have to worry too much about the boost. What it doesn't pass is the visual test. Also I suggests no erebuni kit...... But that is just my opinion.

Nerfdude · 07-26-2002, 04:06 AM

what is this visual test i keep hearing about? are you just talking about the state inspection? because if that's all it is, my mechanic/inspector is a good friend first, mechanic second.

I've kinda been wondering along these same lines. I've read alot about the SR and other than the turbo are there that many advantages over the KA? If you turbo or even super charge the KA wont it be better? After all, you are dropping 400cc DOWN to an SR.
Just wondering

One advantage over the KA is that the pistons and rods are stronger. The SR is made for a turbo therefore can handle more boost on stock internals than a KA. This is debatable however.

It's getting to be harder and harder to decide whether to go KA+T or SR. Sr's arne't as uncommon as they used to be.

Here's a good rule of thumb to follow. If your KA has tons of miles swap motors, if it's still new go turbo.

They are however completely different engines. It's amazing how much the car changes with a swap. Once you go SR you'll never go back!!

newbie's try'n to start another ka vs sr again.. all I gotta say is both swap will cost around the same in the end..  it's all preference.

fuel pump, intake, gauges, and down pipe are def. needed for a swap in my opinion.  Unless you use side mount...  clutch can wait until you go to a higher hp.  (I think you're doin those mods to sr, not ka if I'm right)  Do the issentials first.

Foxcolt · 07-26-2002, 09:30 AM

I disagree about the clutch. better to do a clutch job when motor is out of the car the a clutch job when motor is in the car. Plus with a used motor you have no idea what the other person did to there clutch. For all you know it coulda been some 16-18 year old learning how to drive in japan with legs too short to push the clutch pedal down all the way causing it to constantly slip <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/biggrin.gif" border="0" valign="absmiddle" alt='

I wasn't trying to start a debate, just asking as simple question.

Completely agreed. In your case it's clearly the sr choice, unless you want a really torque engine and have extra $2-3000 lying around to get forged internals.

The clutch... i'd rather save up. If it's really dead, than buy a new one. If it's still good, keep using it till it dies.

Exhaust... i'd not be getting one till like 1-2 weeks before the turbo goes on. Got a couple of personal reasons for that: a. i want big piping for the turbo but don't wonna scare my neighbors while i odn't have the turbo. b. if you were going n/a, than yeah, get it now and be happy. but since it's turbo, the exhaust will give you miserable hp compared to turbo. so why would you put it on right now and throw a completely fine stock system away?

Body kit.... i don't see how that has ANYTHING to do with a swap. If you really want it, get it. If you can live w/o it, save up for something that actually makes your car go faster.

Finally on the KA vs SR debate.... i'd say if you build em up, they are both going to run you about the same. So money isn't sorta an issue.... But the way i see it... SR is a 'racing' engine. Something to go to the track with. KA... i'd say more of a drag/daily driver engine. I'm going turbo ka for the second reason yet i'll still run at the track/autox stuff. Hope that helped...
