A ka24 crank, stuffed into an sr20, stroked to 2.3L, with a ve system, a nice little turbo...and maybe a little nitrous to top it off. Feasible? Hmmmmmm.....maybe my mind wanders too much for my own good

Possible? Yes. Feasible? Probably not. You're talking many many thousands of dollars of work here.

How about instead of wasting your money, just give it to me. I really need an ell ess won :D

Will a ka24 crank work in an SR20DE or VE?

2.3L with stock rods and pistons?

The ka cranks fit...and who knows...all this may come true.......;)

And I may just be the one to do it!! I have an SR20VE and I am buying the parts to rebuild the bottom end and turbocharge it.

I need more information. Do you need shorter rods with the KA crank? What is the negative side?

Well, I could tell you...but then I would have to kill you...no...serious :D. My friend and i who have been pltting this evil plan have thought and rethought many angles, but much machining willb e needed...may cost upwards of a few thousand in just machine work. Upsides are...torque, torque, and more torque. The downside of course is the loss of revablity, which, come to think of it would be a bad thing combined with the VVL. Cause VVL likes to stay high-revving for it's power...and a long throw doesn't like to comply with that fact....on the other hand...if you had a short throw, but long rod length...you could have some mad power there.....hmmmm.....

Hey Chuck, I was reading over you website and was looking at your old car and new project. Was the 14.6 pass after all the modifications? No offense, but even you said it, that is slow :(. Maybe a stand alone programmable ecu system like HALTECH of something may have gotten you a lot faster. Also, I saw that you were going to have the VE's exhaust manifold Extrude Honed....I believe Hotshot makes a custom header for the VE. Just a thought, as I know how expensive Extrode Honing can cost. That is if you aren't turbo'ing the VE.

Anyways, I think my dirty thoughts of a ka24 crank stuffed into an SR should be flushed from your head. I would advise you to keep the stock crank, have it micropolished and re-nitrated, as the nitrile coating is what makes our cranks bulletproof. Then have the whole bottom-end balanced up to say about 10,000rpm...then go and rev like a mutha...thurbo or not :).

My 14.6 on my old black 200SX was with everything. I think air/fuel ratio was the culprit, but at this point I'll never know. There is a local guy here named Ralfy Lewis who bought the engine from me, but I'm not sure if he has taken some of the tuning suggestions I have reccommended.

I'm not willing to gev up top end for torque. My plan at the moment is 87mm Arias pistons, Crower rods, GTiR manifold and an HKS 2835 turbo.

I'm still researching information before I start buying everything.

Chuck,

Have you thought about talking with Rob (ClassicSE-R) about the right turbo. That will be the single most important piece. Good luck with your turbo project. Sorry to hear about your VE.

Steve

I do believe the HKS 2835 was the turbo used on the Disco Potato. Dual ball bearing, spools so fast, you'd think you just had a V-8 stuffed under the hood somehow.

why would you want a ka crank the sr20 is better and stronger. and it wouldn't even it.

The KA crank would give a longer stroke effectively giving more displacement which leads to more torque and power.

this guy was joking around about this whole thing look at his name logical retard. he probally just posted so we can all flame each others stupid ideas that nobody will ever do so why argue with everybody else and just laugh at this guys idea. he was trying to be funny not serious.

first the ka24de only produces 155 in stock form and the sr20de is 145-140 so anybody who does this is stupid. if you want a mixture of the ka24de and the sr20de then get a qr25de(new se-r motor) it'll be a hell of a lot cheaper since your getting a new car with the new car smell.:D

So you're telling me that stroking an SR20 out .3 liters is, direct quote here, "stupid" ?

NX2k, uh, not to be rude, but, you should probably shut your mouth before you keep on talking about something you apparently have no knowledge of.

Using a KA crank as the basis of a stroker kit for the SR has been seriously talked about and I believe JWT has been working on such a project. And in stock form, I'd venture to say the SR is a better motor if you're going to boost than the QR. And if you can't figure out why, go read up and do some research.

Kid, your shot. So are qr25's. That's all. I guess JUN and Toda produce 2.2L stroker kits, and JWT is working on a 2.3L stroker kit for sr's because they are "stupid" right? You are a shame to the Red Sun. Listen and learn before you speak.

Remember, Andreas has a formula for stroking the VE and VVL platforms too. I believe with his program you can have a 2.2 liter engine without modifying a KA crank or purchasing either a JUN or TODA crank. Call him.

(ka24de)
150hp-154lb ft torque
dohc 16 valve inline 4
bore x stroke 89.0 x 96.0 mm
compresion ratio 9.5:1

(sr20de)high port
140hp-132lb ft torque
dohc 16valve inline 4
bore x stroke 86.0 x 86.0 mm
compresion ratio 9.5:1

(qr25de)new se-r and se-r spec v engine
175hp-180lb ft torque(spec v model)165hp-175lb ft torque (se-r)
dohc 16valve inline 4
bore x stroke 89.0mm x 100mm
compresion ratio 9.5:1

ok the single only thing you have to look at here is that the qr25de has a compresion ratio of 9.5:1 so if you can turbo the sr20 you can also turbo it but since it has a bigger displacment it will take a turbo alot better than sr20 and ka24 the qr25 also has vvl it's called cvtc. (let me clear my throat uhm) also they may be making stroker kits because if someone makes there sr20 a 2.2 they can't use the regular crank anymore not to increase torque you want torque get a turbo thats all you'll need. no need in wasting thousands of dollars on somethiong usless you guys arn't nhra drivers your street racers right? why wast thousands of dollars to beat a hond crx you couldve beat in stock form.
