Im sure a lot of people have thought of this and im wondering if its actually possible.....and if it is, does anyone know of any boosted maximas?....i just thought since you see mostly 240s getting the swaps so they can be more Silvia-like i figured it would be a little different to swap one in a maxima......

 

I'll be the first to call you a nOOb, tell you to read the STICKIES, stop asking dumb questions, and first to say IBTL.

 

anything can be done with lots of money, but realistically No it cant be done, why would you want to swap a turbo 4 cylinder into the max? by the time you manage to get everything working you could have just bought a turbo kit for the max and saved a lot of headache.

Yea I gotta admit its not a dumb question but damn it feels like it. if you think about it, it would be far too much trouble just to get it to work.

 

maybe im new to the forum, and new to nissans all together, if you think its stupid to swap a sr20 into a maxima then why dont you go tell Motorex that it was stupid of them to put an SR20 into their 350Z?? im not trying to start trouble or anything, but if you can do it to a 350 and no one talks **** about it, then why not a maxima??? i took some pictures of the article cause i didnt have a scanner....

Engine swaps in a Maxima aren't quite as easy as a civic, considering they have only been done by maybe 4 people. But yeah, by the time you bye the SR20 and everything you need to do the swap, you could have turbocharged the VQ30 and have twice the torque as a SR20

 

not to mention youd be hard pressed to find room for a turbo in the 350z's engine bay, so the swap was out of necessity to have a turbo

 

actually, they blew the VQ35DE that was in there originally and they decided to save weight and throw in the Sr20....hate to say, but theres a twin turbo kit from Greddy for 350s so i dont think its too hard to find room for a single turbo, much less two of em....

 

its easier to swap the sr20 into the Z, their both rear wheel drive cars, the Max is FWD so you'll have to convert that as well.

I think I know the Z your talking about, and if you saw it on Redline then they did that so that they could drift the Z easier and lighten the car up since it was so heavy in the front, lighter front heavier back makes it much easier to swing the tail out. thats why they did that.

but a Max with an sr20 would be far too much work since you'd have to make drive shafts, redo the rear completely, its just not worth it.

not starting nothing either just emphasizing my point.

 

well, if youre that set on doing it, go ahead, have fun, do a write-up on it. the only problem i'd think you'd have is that, unless im wrong, most of the SR20 cars are RWD and I dont think the VQ tranny would bolt up too easily.

EDIT: damn you beat me to it by a minute!

 

lol

yea I keep checking to see what everyone else is saying too

 

I have seen a Max with an supercharged SR20 and ecu swap. Speed TV? It was strictly for drifting. Not for speed. It took about 200 lbs of weight off of the front wheels. They also stripped everything else possible off the car and lightened up by 700 lbs. Looked like ****.

An easier and cheaper way would be to import a vq20 engine.

 

I wonder why they supercharged it instead of keeping the turbo??

thats odd, I'd figure the 240 would be better for drifing? maybe the long wheel base of the Max makes it better and more stable to control?

there was a vq20?? what car had that?

 

theres a guy in town that has an older Sentra with a SR20 setup for FWD......i didnt mean i would swap a SR20 and hope to have the fastest Maxima, i just thought since it was an uncommon swap it would be interesting to see one.....i guess ive got more of the mentality that if it hasnt been done before then ill ****in try it

 

dont get all touchy, were all here discussing this with you you just came to the forums.

I dont think it the "mentality" issue as it is more of a money and time issue, I know I'm not saying it cant be done, anything can be done, it would just take a lot of custom work, and trial an error.

As much as I would love a RWD Max, as as much as I love customizing and creating new parts, that would be to big of a project for me, I'd rather just buy a 240 and do the swap, but thats just me.

 

Lets say your going to keep the FWD layout... why would you go to a torqueless 4 cylinder rather than just boost the VQ, you'll be making more power anyway

 

They do make SR20DET motors for FWD applications. They also make em for AWD. There are 10x the number of modifications for the SR over the VQ. Not to mention you can build one up out of books. It's easy to get cheap, reliable power out of the SR. Not so easy on the VQ. Nonetheless, as the old saying goes, "There's no replacement for displacement." It's all a matter of choice.

Well, I think it was a supercharger. I prefer them since they are lighter and you have a less restrictive exhaust. IMHO

I think the idea is like 4thGenGXE's. Something different. Like Jesse James putting a vq35 into an old HoneyBee (Datsun B10 ?) Monster!

See UK maximas and commonwealth sites for the vq20 and vq25 motors.

 

They may have put an sr20 in a 350z but IIRC quite a few racing 350z's have the vq30. It simply take boost a lot better then the vq35.

 

SR20DET in an A32 chassis has been done, it's definitely possible. The VQ30DE is proving to be just as strong, if not stronger under boost.

 

..... Why would you swap a much smaller and much older (in design, if not in years and mileage) engine into your car? The VVL ones are nice but you could do so much with a bigger and better engine i.e. the VQ. You had might as well swap in an RB26DETT. Right now the VQ30DE-k and the VQ35DE are the only engines I can see being swapped in. The -k gains are mostly from the manifold and that could just be swapped in alone. The VQ35 is great and has a lot of potential but you would have to use hybrid parts or set up the VVT and the Drive by wire. I can't see it being worth it unless you are after crazy big hp. I would also recommend building a VQ35 if turboed since they don't seem to handle boost as well as the VQ30 which just adds to the cost of this swap.

H22 swapped Accords are fast, but honda focuses 4 cylinder engines. GM, Ford, and Chrystler focus more on huge V8s. Nissan for the most part is known for their good 6 cylinder engines. The L, RB, VG, VE, and VQ are all known to be fast. The SR is the only one that is really known as fast. Some would argue the QR and KA possibly, but none of them are in the really fast cars. The Silvia/240sx and Sentra SE-R/Sunny/Bluebird are all almost considered 2nd tier sports cars. The Maxima and Z have always been faster much less the Skyline GT-R. The Sentra SE-R was in some ways to compete with Honda over the 4 cylinder tuner market. The 240sx is more designed for drifting.

There are plenty of FWD SR20s. Look at any older SE-R. For the SR20DET most people use come out of JDM cars that are AWD and just use a FWD tranny. The FWD/AWD SR20DETs are actually cheaper than the RWD. The 240sx and sentra were designed to be able to have that engine in it. It is a relatively easy swap. The Maxima is designed for a VQ. In japan and other places they have the VQ20DD and VQ25DD. I have never heard of any 95+ maxima with any engine besides a VQ of some sort. I don't doubt that they could exist. I am saying they are few and far between.

The swap for the SR20DET into a Maxima may not be that hard. Smaller engine means a lot of room to play around with. The motor mounts may line up who knows. The tranny and axles are questionable. You would have to have a new wiring harness and ecu. There are a lot of things to consider in order to get this swap working. For a turboed maxima you get the turbo kit or have one built custom. You get lots of power. You may have to build engine eventually and it really isn't that simple but throwing an engine swap complicates things more.

There may be more modifications for the SR20 but it would have to be modded pretty well to get to the 450-600 tq range and have the area under the curve that a turbo VQ has. There are also a lot of different engine rebuild kits out there for the SR20 but by the time you spend the money on the engine and then even more to build it, put in a new turbo, and get everything fabricated and set up right you have spent just as much if not more just to get it to where people have gotten the VQ30 turboed on stock internals. Hey you have done something no one has done before, great, but that is because most people figured it probably wasn't worth it.

Our cars come with a really good engine stock. Why are we trying so desperately to change it out? We don't drive hondas where are cars have 8 different engine options and trim levels. Nissan has a lot of cars with the VQ in it. They must really believe in this engine.

If you really want to try the swap, then do it. I would be more than happy to see more pioneering and experimentation for the maxima community. I suggest you do a lot of research in the subject of engine swaps, turbocharging, and engine mechanics.

Wow thats a long post

 

The ONLY reason to do this would be to be "different" and IMHO it would also be retarded from a performance standpoint. You'd be taking a step backwards in performance from stock not to mention the unknown complication factor. The SR offers no advantages over the VQ except that there are more parts available for it. It is not lighter, it won't hold any more power than a stock VQ, and as there are folks pushing upwards of 500hp on stock VQs and none of them has yet blown, it's very likely it has less power potential without opening it up. Wiring, who knows how easy or nightmarish that might be. Engine mounts, who knows. So basically if you swap in a stock SR20DET and you are as slow or slower than your stock VQ was, but you just spent upwards of probably $3000 for it... not a brilliant idea in my mind. Unless you have some strange desire to take it to car shows and show off a pointless swap that the drift bois can drool over.

 

the top secret supra in japan runs ona mr2 motor granted it is the japanese mr2 version motor. and running 700 horses. it was more of a thing to get a weight balance of 50/50 but swaping a 4 banger in a max that doesn't make sence to me why did you buy the max should have bought a 240.

 

Top Secret and companies like that do it mostly for the Wow factor, supra motors in skylines, skyline motors in supras, etc. The cars they do that to are big rolling billboards for their shop so they need to get people looking. The reason they put an MR2 motor into their 240 was because the MR2 motor behaves better at 9000+ RPM and that car was a car they were trying to beat a top speed record with. That's what some article I read said, it's not like I asked them myself heh.

 

Why not. Ive seen it done to a G20.

 

240sx people do a exterior conversion to be more like a silvia. They swap motors to be faster.

A G20 comes with a SR20DE stock. It is better to swap a FWD SR20DET to it than to turbo the NA version.

Is it possible? Yes
Is it worth doing unless you just want to do an original motor swap? No

 

in september 2001 issue of super street which did an article on the top secret supra said it was for a 50/50 weight balance and alowed them to push the mr2 motor closer to the firewall

but yes mostly for wow factor

 

You can fin BB-Det and Avenir-DET in FWD really easy.

I know my old motor pretty well and most the arguments are valid...If they made a reliable kit for SR20VE maybe it would be a diffrent story, but I doubt it.

I would stay with the VQ your gonna lose alot of tourge and the VQ series seems to be as supported (aftermarket) as the SR series.

Dyno from a FWD G20 with GTiR swap, T3/T4, Tial 35mm, Custom header, 3" turbo back, S3M Cams, and a blown clutch.

 

What other motor can handle over 3X times the amount of torque all stock?
(VQ30DE) is one of few or any that I know of.
AND Reliable too






I would do AWD SKYLINE conversion on a maxima. That would be the
****

 

well, whats the point of having the look if you havent got the motor? the first step i would ever take in trying to go from 240 to s13/14 would be to get the motor.....**** all the headlights and tail lights and grills and ****....that comes last

Ok... I have one question, why did you buy a maxima? Most of us here baught it not to make it a racing machine, but to take the clean, and nice lines it already has, and make it so much more... Im not saying there arent any incredibly fast maximas, but i am saying that it was never ment to be a race car. I baught my maxima because it was a perfect balance of speed, and luxury. I will mod it engine wise because i would like to have 200fwhp, but i would never make a race car out of it... If i wanted to, i would have baught a 93 300zx... Much quicker car, and much more potential to be a racer IMO. You should do the swap if you really want to... It would be pretty cool to watch. But i dont really see the advantage it would give you...

 

Why not instead try to put in the T, In your VQ30DE, sr's arent all that as everyone puts em out to be, I mean yeah sure there known for getting all those damn parts for everytthing. It aint worth it, unleass you want to be unique so they say. Yeah Peace out!

 

SR in A32 in my opinion is pointless......torque factor for one.......to get the nice powerband (torque curve) that the VQ has out of the SR would be lots of money....more money than it would to be FI the VQ motor and still have a reliable car.....the SR is known for its high numbers on stock internals mainly the bottom end.....but if ur spending the kind of money to do SR in A32 ur better off doing Skyline AWD set up or just completely going all custom shi.ts with the VQ power plant

 

not true, they have twin turbo 350z's

 

not all SR20's are RWD, sentra ser's come with a fwd sr stock.

edit: i need to read better.

 

If you could stick a SR20VET in the sucker...that would be a project!

GTiR swap is sweet...thats the real deal.

One thing I will say that some other people have said is you can mod the crap out of the SR20 block...its BEEFY...including the internals.

But as far as getting rid of the VQ30? I'd rather have a blown VQ30 than a SR block in an A32.

 

Are you kidding? Hal is making 530 HP at the wheels and 605 pounds of torque with his Turbo 3.0. Getting that much torque out of an SR would be muuuuuuuch harder. Supercharged maximas make can make over 300hp easily, the only weak link is the tranny, and it's still stronger than an SR20 tranny. I know someone with a FWD turbo 2.0 in his Sentra. Had to rebuild his tranny... 4 times.

I have to disagree on this one. There is a guy I know who has a 600hp Turbo 350z and the only real weak link is the tranny. It's just that the VQ30 had 7 more years to get its FI choices perfectioned.
