more power out of the b15 style

hey im new to the sentra boards i just bought an 01 sentra se, and im looking for a new engine for it preferably turbo that will fit in and run properly, anyone have any input please respond

QR25DE , You will need engine harness and ecm. Turbo kits are available for them. You will also need some of the other components mounts and such. I am not sure if any one has done this swap yet if not you may be the pioneer for it.

is that the engine out of the 03 and newer SER spec v?

Post by **NISTECH** » Wed Mar 03, 2004 6:43 am

02 and newer

Post by **NISTECH** » Wed Mar 03, 2004 6:43 am

the sr20DE you have also has turbo kits available.

Post by **01sentrasr20** » Wed Mar 03, 2004 6:43 am

yes but i was looking at a bluebird engine which has a turbo and is cheaper than a turbo kit for the sr20de

Post by **spec-u-later** » Wed Mar 03, 2004 6:43 am

Wouln't it be cheaper just to go with the bluebird sr20det. The QR25DE has kits now but they are a bit costly.

Post by **NISTECH** » Wed Mar 03, 2004 6:43 am

I'm not familier with the sr20det sorry.

Post by **01sentrasr20** » Wed Mar 03, 2004 6:43 am

i am looking for engine mod parts for now with the sr20de engine till i get enough money and time to do the swap, and mabey if it pulls the way i want afte the stock engine mods i might just break down and buyh the turbo kit for it even tho it is a bit pricy

SR20DET is becoming highly demanded. At least $1700 for the motor not to include shipping. Then you need a clutch, Downpipe, spark plugs BKR7E's, motor mounts(recommended), boost/oil pressure/a/f gauges, oil(mobil 15w-50recommended), tranny fluid(shock proof heayweight(recommended), fabrication to your hood for TMIC or FMIC, catback exhaust(3" recommended), water pump, all belts, antifreeze, other small accesories and S-AFC since JWT hasn't cracked the code for the B15 yet. It becomes a pretty expensive swap if done properly.

Might as well get an SR20VE for 1900$.

There is also some other costs involved, but I thinkthis will be a nice setup.

Also JWT is currently developping wicked cams for itsomething in the amount of 30-40whp over stock.

And they are newer engines, more reliable, N/A.

Turbo what you have, if you can't afford an SR20DET from Japan. In fact, I'd rather turbo what's already there anyway, simply because you know at least some of what the engine has been through, and thus the condition it is in.

VE would be nice, but N/A is limited when you have 2 litres.

I think it should all depend on what you really want to do... are you just looking for a fast daily driver, or something that's quick on the strip or can tear up the track?

If you are looking for the track, you probably don't want the SR20DET.. too much power, and you really won't get the full potential of that engine anytime while on that track.. n/a usually works best.. so I'd stick with a SR20VE. The SR20 block is more reliable than the newer QR25, which if you wanted to swap, you'd need some new parts. The QR also has a few issues of it's own, and while the QR itself can be cheap... it's more expensive to turbo it... and without shelling out thousands more for stronger internals, you won't be able to boost more than 7-8 psi unless you plan on replacing the engine.

However, if you're looking for 1/4 speed, you'll want the SR20DET.. the SR20DET comes pretty much ready for more boost.. it's more safer to incease the boost to a turbocharged engine than to add boost and increase it on an engine that wasn't designed for it. There are tons of 11-second SR20DET equiped B15 SE's floating around..

SR16VE , SR20VE and QR25DE for N/A applications.

SR20DE,SR20DET and QR25DET(See Fi-R.com) for forced induction applications.

I personally reccomend the B13 SR20DE High-port engine with a G20, or JWT ECU

If you are looking for a quick track car (as in, road coarse) then just do bolt-ons to your SR20DE that you have. If you really want to swap a motor, go for the SR20VE.

If you want a fast drag car, then I recommend turboing the motor you have. You can make better power by turboing the SR20DE than swapping in an SR20DET. The SR20DE has been out for long enough that turbokits for it have been developed to perfection. I know of multiple people who have broken 400 whp on a stock bottom-end SR20DE. No point in getting the DET.

I would like some names and websites or dynos, just out of curiosity. I was under the impression that the SR20DE was much weaker internally than SR20DET. 400whp on stock block? multiple people? daily drivers? sounds... too good.

There are all the exact differences. I would say that the 400+ is a myth, or I have "reliable info", but that's not the case. I have first hand info. As in...my friend John is one of the people who have put down over 400 to the ground. He has a '90 Sentra with a turbo'd SR20DE under the hood. Also, Jay Hassinger posted dyno charts to the se-r mailing list way back when showing 409@wheels on a stock internal DE. If we were to drop down to the 300+ range, I can find 10X the people easily.

YouTube · Post by **EZcheese15** » Wed Mar 03, 2004 6:43 am

Anyway, I can't find any websites with that info you want....but keep this in mind. Sentra guys know SR20DE's inside and out. They've been out since 91 and we've been researching and developing them since then for power. 02 was the last year the engine saw a USDM car, so most "new school" sentra guys don't really know what has gone on in the past. 240 guys don't have a clue either, because who cares about the SR20DE when the SR20DET is just as easy of swap (if not easier).

Basically, if you would have been part of the Sentra following 3+ years ago, you would have known about this stuff. Unfortunatly 240 guys usually give the DE a bad rep because it's not turbo'd from the factory. But take my word for it, the DE is bad a**.

Oh, and as for names. If you can find anything, Jay Hassinger and John Abbott are the names that come to mind for over 400@wheels. There are more though...I'm sure John knows pretty much everyone at that level. BTW... John is "nismodriver" on AIM.

Post by **sil80drifter** » Wed Mar 03, 2004 6:43 am

EZ, cool.I was just wondering, I'm not one to doubt an NA engine's capabilities, what with trying to turbo the KA and stuff. Just wanted to know. Thanks, and WOW. I wonder if lots of the 400+ guys are running standalones and etc. Also, if it's done on a daily basis or not. The thing is that when an engine is not designed for a turbo/high power (like no piston oil squirters, smaller oil pumps/boost oriented cams etc) you CAN safely bring it to a high HP level but the question is how long will it last, before the unusually high stresses of the forced induction will start eatign away at it's shortenign life span. And yes, any engine will go eventually, but all things equal, if two of the same engines run the same tuning, and one has forged internals and the other doesn't, I would bet that the one that doesn't will have a shorter life span. This is off topic, I know. Thanks for the info though, and more power to those guys.

Don't know about other people, but John is running a JWT ECU I'm pretty sure.

Post by **sil80drifter** » Wed Mar 03, 2004 6:43 am

that make me give jwt one browniepoint. still dislike them for their pricing and inflexibility of ecu mods though.

Oh, and I just remembered....for what it's worth, I remember that Jay was also running a JWT ECU. I think he had some serious problems that he couldn't get his car to run right, and it turned out to be a bad ECU. But if I remember right, it was a JWT and he finally got it reprogrammed and it worked wonderfly.
