se-r 2.5 into s13

[jak89]

Are you serious? it does bolt up? If i go buy a QR and it dont bolt I'm gonna be pissed.

[safin]

The interesting this is the QR25DE bolts right up to the KA 5 speed transmission. It has been done before a few times, the 510 guys are doing it.

I am trying to get a local friend to do it. The intake inlet is an issue, but can be worked around. But out of the box they are great engines depending on the year and trim they offer a solid 175-185 HP/TQ and are very boost friendly.

I've heard that beforeany swap would be cool in a 510.

12sec sentra? I'm not impressed.just turbo the KA..............or....SSSSSRRRRRRRRRRRRRRRRR it

lol apart from the originality, those numbers are kinda pathetic and definately dont justify a custom (headache) swap of this magnitude. maybe thats just me tho...

[Hooked on 240]

why?

This.

I believe what he is saying is that the transmission will bolt to the engine WITHOUT modification, but the engines mounts WILL REQUIRE Custom modification to work in a 240sx chassis.

True.

I think its a the KA 5 speed, Frontier flywheel starter and I am not sure what clutch. Pathetic swap no, motor revs good, make 175hp, and likes boost. Plus you can snag them for like 400 bones. So if you can fab and weld up mounts and wire it up you are golden.

[J14cm7]

I still think this is a project that could easily get out of control cost wise with the result still being not all that impressive.

[OutToWinPAHC]

Yeah, thats why you need to know what your doing. But its a new current motor (Sentra, Altima, Frontier, Rogue, ETC). You can get them dirt cheap with low low miles. Sometimes even under 15K for 500 bucks.

It's a very proven engine, used in FWD and RWD Nissans, and with some time, welder, steel stock, solder iron, and line tools you can pull the swap off for under 1500-2000K all day long. It's hard finding a good KA with under 120K miles anymore. A lot of the 2.5 pull are coming from crashed CVT altimas that some woman crashed on her way to soccer practice.

[biggie]

Did they ever upgrade the stock QR rods? Those things were tiny.

[OutToWinPAHC]

Intake issue solved.....

Frontier 2.5 intake faces crank side, unlike the FWD car side. The truck variant is a lower HP motor but the intake can be swapped.

So KA or frontier trans, flywheel, starterQR25DESR radiatorCustom motor mounst, plumbing and wiring.

This is all good info, outtowin is the man as usual, but why not just go sr for less? Are the internals really that much stronger than a KA? Is the reasoning behind doing this swap just to be different or because the end result will be better?

[OutToWinPAHC]

I like the idea because it is outside of the box. Redtops, blacktops and KA's are high mileage and for the most part pretty beat up on.

So I like the QR swap because you can get a great motor, proven with low miles for cheap, boot it to a relable 300 HP. Parts are also available, it just another option.

[jak89]

Hell ya I think I'm gonna start on this in a few months As far as fab goes I am a welder/ Fabber just new to it i have like 8 months experience i think the mounts n s*** will be fairly easy. the transmission stuff is what I WAS worried about.

The main reason I am thinking of doing this is the age and availability of parts also the spec v motor is a good boost motor

if I get this done i'm goona be doing better than 12's

From what I understand now the wiring could be the hardest part?

[J14cm7]

12s? How much boost are you planning on running on a stock block? You say the QR can handle boost but dammit man how much are you planning on running?

[slow40]

Turbonetics made great power out of their turbo kit for the spec-V. That's what I would look into getting if I were to do this swap.

[locoluna825]

Do the QR ecu's run on CAN?

...and giving up. Havent seen a successfull qr swap in a 510 swap yet..and I'm a 510 guy lol. Most of the attempts are being made for an all motor setup using the jdm qr20de's hi comp pistons (qr9.5-1, jdm qr 12 to 1 the bore is the same). Most are just opting for all motor sr20/sr20ve's bcuz its cheaper and easier. Not that I wouldnt mind seeing a rwd qr...in a car that is

Just Between the significant weight difference and being rwd instead of fwd should make a surprising improvent and I'm not sure but i thinkthe KA gearing could be better for the accelaration

Whats a CAN?

^^ I usually dont quit something until its done so hopefully this wont break me.

[locoluna825]

CAN is the new system that came after OBD2 diagnostics systems. I looked it up and these motors are CAN.

I dont mean to be negative or a hater but i think under 12 is a little unrealistic for a 240 thats only putting out 300HP. I think if you got into the the high 12s you should be extrememly happy with the results.
