sr20det in maxima
hey ive heard of sr20det's in sentras but what about a maxima a 94 , if not the sr20det then what a v series motor maybe ? a rb26dett ? what swaps are possible , im trying 2 make the ultimate sleeper car , thanx for the help guys

you could do a vg30et but you can't do vg30de, vg30dett, any rb series engines, or basically anything that is bigger than the ve30de. the sr could fit but would take a lot of fabrication to get it in there. you could probably get the bluebird opr pulsar engine and get a 5 speed tranny from a sentra se-r that has the sr20de in it. from there, you would need to fabricate all of the mounts and do all of the wiring to make it all work.
it would be an interesting swap to do since the sr's can be very potent engines. they are easier to mod than the stock engines in the maxima but they wouldn't pull as much torque. it would still be fast as hell though

Forget the RB series engines - they're longer than the VG (inline 6 as opposed to V6) and all use rwd trannies - no fwd tranny will fit as the bolt patterns are completely different between the engine & the bell housing.
The SR20DET is gonna have the power but not the low down torque that you need for takeoff. Better to find a used Japanese Domestic Model SR24DE, bore it out to 2.5 liters, turbo it, get a 5spd tranny to suit (from JDM Pulsar GTiR), turbo hubs & driveshafts ('cause the maxima axles are not gonna fit the tranny and the other axles aren't gonna fit the max hubs...), fabricate engine mounts, tranny mount and wire in the computer to run said engine.
Ultimate sleeper, maybe... Ultimate money pit more likely!
Me, I'd rather get a VG33E & turbo it - although not sure how much stress the VG33 can take...

jdm sr24de?!? never heard of such a thing. are you talking about the usdm ka24de? its a strong engine that has tons of potential but the sr would still be better than that just due to how much aftermarket support it has.
for the axles you could just have some custom ones made that would fit whatever tranny you used along with the maxima hubs plus they would be stronger.

Not sure using lighter KA engine would give you any real advantage over a VG30ET setup though & much more work involved...

Just get a vg30et custom it out to a twin turbo or put int a hybrid t3/t4 turbo in there. All you need is a freaking turbo 84-89 300zx to do it. The only fabrication problem is one single engine mount. That's it.

i don't know the maximum numbers yet but i do know that terribly tuned it made 16x hp at 4100 rpm and 20x ft. lb. of torque at 4000 rpm on a mustang dyno. my intake pipe popped off during that run which didn't allow it to go any higher. on one of the test runs my friends and i are pretty sure we say the computer read over 200 whp though. i just recently bought a plx devices m-500 so i'll finally be able to tune the thing to get more power as it was definitely running too rich.
and i'm almost positive there was never a SR24DE in production. the only SR with a different displacement is the SR16VE. also, there might have been a 1.8 liter version but i'm not finding it yet.

MT is pushng soo much power that the intake isn't sucking anymore that thing is flying everywhere. 200whp at 4000rpm can't wait to see it around 6k rpm. Are you using the stock turbo. Good work. BTW MT do you think that 1700 for a rebuilt 300zx turbo engine is too much. I'm saving up for it.

yup, using the stock turbo non-intercooled.
1700 seems a bit high for one, even rebuilt. they can be found for much less and still last for a long time. i personally bought mine for 500 dollars and it was in pretty good condition. being jdm they usually say it has around 60k miles or so which isn't much at all. a plus with the jdm engines is these were in a more of a luxury car that only came with an auto tranny so most likely they weren't driven on very hard. that still doesn't mean that it was taken care of (oil changes and such) but it helps in assuring it wasn't beat on and such.
ebay has a few jdm engines floating around every once in a while. www.z31.com classifieds is a good place to check and probably the best place to check would be www.car-part.com they seems to always have engines listed. i've not searched for any importers that carry the jdm engines yet but i'm sure there are some out there.

another newbie ?
alrigth guys sry for teh dumb ?'s but i just got turned on 2 maxima's before this i was a 240sx guy , i dunno what it is but sumthin about the 3rd gen maxima appealed 2 me but alright here i go the vg30et is from the 88-90 300 zx right and how much should i pay for it? what about the v series motor form the 350z or the g35 ? what kinda fabrication would i need for the sr20det swap which is what im thinkin of doin? im sry for all these ?'s but im really interested in what i can do thanx alot guys

your best bet would be the vg30et swap from the 87-89 300zx. its almost a direct drop in. you either have to make a custom motor mount (i'm working on getting one made that should work well with this swap) or relocate the turbo.
the sr20det would require quite a bit of fabrication (motor mounts, tranny mounts, and tons of wiring).
if you want some more info on the vg30et swap you can check out my cardomain site http://members.cardomain.com/mtcookson

Quite frankly, $1700 is a little low for a rebuilt VG30ET. Im rebuilding one right now, and Ive spent more than $1300 on internal parts alone. (That doesnt include injectors, which some of you already know is close to $1k for the 6) Unless you are planning on putting out more than 300hp, a used low mileage VG30ET is the way to go.
As for an SR20DET not having enough torque for a maxima........ maybe if you took the turbo off. A stock SR makes more torque than the VG or VE. Not to mention the severe weight loss over one of our iron block V6s would only help the maxima that much more. Not that I think putting a 4 banger in your max is a good idea.....

I don't know of any engine swaps in a 3rd gen yet, but I've heard about someone converting one to rear wheel drive and dropping in the VG30ETT, but who knows. Post pics when you are done with your project philmax1, and good luck.

If you convert a Maxima to RWD you know what you end up with........an Infinity J30. Its basically the same car except one is FWD and one is RWD. I've seen a J30 with a 300Z Twin-Turbo swap with trans and all which is simple since the non turbo 300Z has the same engine as the J30. That is a total sleeper since the car still has the stock rims on it and a quiet exhaust.

SR18DE's are easy to find - standard engine on NZ & Aussie NX's (known as NX Coupe in Australasia & Japan) and standard on JDM U12 & later Bluebird SSS's.
Whilst the net is a great research tool, it ain't perfect - I've never heard of a SR16VE or SR16DE for that matter, because it wasn't fitted to any Japanese or NZ Nissans we get here (we get the GA16DE engines instead). Doesn't mean to say it don't exist, though...
Also, be careful when buying used JDM engines - some "quoted" mileages are much lower than reality - sometimes up to half the true mileage! We have had plenty of used japanese imports with "only 60k" on the clock that really had double the mileage.
Fitting a SR20DE to a max is like fitting a 2.4 liter turbo engine from a PT cruiser to a 300m - the engine may be lighter & develop as much torque, but it's got a heavier body to haul around and you know it's gonna develop most of it's torque high up in the rev range.

i definitely plan on putting a bigger turbo on in the future. i'm hoping to do a frount mount intercooler setup with a T3/60-1 turbo. if i can get the tranny to hold a lot of power, i'm going to push as much power as i can out of it.
