SR20DET motor?

[Smurf333]

OK so I am still kinda new at this i found a SR20DET motor for pretty cheap is there anway to get this to fir into my 1986 Maxima.Obviously there will be some modifications that will have to be made if this could work what would they be ?

[Jeff92se]

Um everything?

Is it near impossible?

[Jeff92se]

For who? Me? You? Foose?

You seem to want a step by step instruction. Ask here: They know everything:

Impossible....hardly. A big project...yes. Basically, if you can get engine alignment right.....and are really good at building a wire harness...it's doable.

this guy, its not a stupid question but its a loooooooooooooooooooooooong and big project and good luck to you.

[Smurf333]

Thanks for the help.... Any advisory before I dive in would be great. Thanx!

[Big_E-Dog]

as a matter of fact I might get scolded for this but sell the max and buy a 240 sx.
much easier that way.

[Smurf333]

mmmmm.... I love my max but I admit I have been thinking of buying a newer one or going for a different Nissan

[maximase86]

SR20DET in a 240sx is really overrated if you ask me. Not saying it's bad....but everyone and thier neighbors dog have done that it. I'd look at turbo'ing the KA itself or going for the smaller RB's.

Honestly...you want some speed for your car...the VG30ET is probably going to be easier to do.....or turboing your existing motor.

well i didnt say rb25dett, rb25det, or rb26det, dett, because theyre illegal to have here in california unless you put some major dough in smog control because if it was possible i would of have saved up all cheese in a major way to do one. i just didnt think bout the other states. but i have seen a bout 2 street legal nissan skyline gtr r-34's down here. only the selected few.

[maximase86]

We actually have a rb20det up here. Though the guy doesn't have nearly enough money to do anything to the motor since he blew it on just getting the motor and putting it in the car. And that's the other thing too that makes SR20DET's so overated. People blow thier money on the motor....and they can't do anything to it. Their freaking broke. For the same money, you can turbo the KA already in the car....and potentially make more power than the SR20DET.....or at least have more torque. People always say that the SR20DET will make more power......but how many people actually have the SR20DET that makes more power? Not many because they are all broke! Sad part is a good chunk of people that do the SR20DET are fairly young, don't have great paying jobs....and will probably be paying for that motor for time to come.

ok i dont know much about 1st and 2nd gen max's, but if its a true jdm sr20det it will be rear wheel drive and will cost more to put into a front wheel drive (i dont know whether your max is FWD or RWD sorry) but if you go with a US sr20de, there are a lot of options for things that can be done to them. tilleys99 was running 12.5's at the track consistently in his 92 se-r with a turbo and stock internals.... if at all possible, get a us one and go that route. also, KA motors dont stand up to turbos as well as other nissan motors, which is why they arent done as often. also, as far as i know, the parts are harder to come by..... while i agree that rb motors are overrated, i think an sr20 would be a good swap into an early max (ultimate sleeper )

either way good luck, and if i was wrong about anything please let me know...

[maximase86]

2nd gen's are FWD. Didn't realize the KA wasn't as boost friendly as I though.....much like how the VQ35 is as well.

from personal experience, the 3.5 is really good for all motor! i much prefer it to the vq30 in all reality, the sr20 is one of the best motors on the market for turbocharging, but the ones from the 200sx se-r's are supposedly not as good as the ones from the 91-94 sentra se-r's, although the transmissions from the 91-94 have bad 5th gear pop-out problems, so the best setup would be a motor from a 91-94 and a trans from a 95-98? se-r

[maximase86]

Yup, VQ35 is an awesome n/a motor, but VQ30 is much more fun when boosted. I'm also a diehard VG and L-series fan.

lol i didnt want turbo, cause i drive at least 50 miles a day for school and i dont have a lot of faith in the reliability of turbo.... but they are awesome when turboed! gotta love nissan... did you see the post that the vq is Ward's best motor for the 11th year in a row? thats awesome, nissan knows their sh!t

[maximase86]

That's why you go S/C with like a nice 3.125 pulley. Either way, I love the VQ. I get to work on iansw boosted 97 all the time. We got that sucker pulling 339 or so at the wheels. Nissan had the 6 cylinder motor down to a science since the 60's. That's why the VQ is what it is.

I'd pop that SR20 into something classic like an early 80's 200SX hatchback. That'd be a sweet sleeper! Those old 200SX's can look pretty sweet when there done out too.

tilley is going to put a vq30 with a 350z trans into his 280z.... and then he is going to turbo it.... he is crazy lol

[turboast4]

Technically, the SR20DET is illegal in states too. As far as being overrated, it's hard to say. They are popular, and can push 300hp on stock internals. But they are expensive. An SR swap in an S13 can easily cost 4-5 grand. Since you say you can get it for cheap, you might as well try it. The KA is boost friendly, and at 2.4 you'll get some decent torque. It just doesn't rev the same way the SR and CA do, however. The Stanza is basically a Max but the KA24. It would be a nice project to boost one of them.

[Big_E-Dog]

well i guess the turbo edition is illegal because we have g20 and those have sr20de and the 200 nx interesting?

That's right - remember - it's a priviledge....don't make me angry!

i would think a CA18DET might be a little more logical because i know in other countries it was a production option and parts would be more rediably available so you wouldnt have to make so much on your own. but thats just me

like this review in the UK:

[maximase86]

This is my personaly preference....but if I want to make more power....I can't see the benefit of reducing the displacement. While both the CA18DET may be a good motor, you drop over half a liter in displacement. Mod for mod...if that same motor we're made with a larger displacement, you'd make more power with the higher displacement motor. Then again, potentially there could be a weight advantage with a smaller motor.....but I've seen smaller motors weigh more than bigger motors. Case in point, my VG30E probably weighs more than a VQ35DE. But of course I'm not telling people they shouldn't do whatever they want to thier cars.....I just don't see why one would do it.....and there could be plenty of good reasons for it.

A built 4-banger on the U11 will still be slow. The car weights a lot more than the 240, or stanza. Thats why they turbo'd the japenese version because it couldn't produce enough power to the wheels. And even with a turbo the car still was sluggish. What was it called sarin? The bluebird, or le gran or some weird name. I can't remember.

[turboast4]

200hp is 200hp no matter if it's in a Max, Stanza, or 240 (and it beats our stock 155). The CA18 is the oft-overlooked turbo 4cyl that could. Much cheaper swap than the SR, it loves to rev. It's a bit harder to come by, and there are more SR parts than CA parts. It comes to preference really. Both engines have immense potential. Good luck with whatever you decide.

[maximase86]

I dunno man...the VG20ET makes more power than a VG30E by at least 15hp. I don't think the japanese made a turbo maxima because an N/A VG20E wouldn't make enough power. Also....US spec motors trail JDM spec motors. Th
