how much more $ is needed to the bbdet to make as much horsepower as the stage 2 fmax. the reason that i am asking is because i bought my nx2k at 109,000 miles and i may need a new motor (weird noise comeing from engine). is there any place to go to get the motor check. to make sure it can take the boosted duty? i want 300 plus but i want to spend the money wisely, so if it calls for a new motor i may go with the bb motor AND 1 MORE THING what features the bbdet have over the US sr20de? SO if i go far a new motor i know i can find a us sr20 cheaper than a bbdet i just want to know if the bb is all that over the fmax stage 2 kit any links and comments would help

and keep in mind that a bbdet with some type of warrantie http://www.heavythrottle.com/ is about $1900 and god know how much to install it and on top of that it needs pipes hoses thig of mig jigs. it will be more than the stage 2 fmax kit. so why do you guys swap out the motors? a fmax kit would produce more power per dollar? so why do it? is the bbdet all that over the sr20de?:confused:

In matters of reliability, I'd absolutely choose a real SR20DET over turbocharging a DE. The DET has lower compression and cooling features like oil squirters in the pistons that make it that much more reliable under high levels of boost than a DE. Don't get me wrong, the DE is a fine motor, but given the choice, I'd settle for lower initial power levels knowing that I can go higher at will with no fear whatsoever. How much is your paranoia worth to you? :)

On top of that, many DETs have less than 40k miles on them, many of those less than 30k, so you're doing a significant upgrade from a pure wear standpoint. Replace the rod bearings, notch some web off of the block, drop it in, and go. Call Hot Shot or somebody about a downpipe and an FMIC setup, and you're ready to roll in a serious way. Add a GTi-R manifold and a T28 for more power, or even use your DET as a basis for F-Max parts in the future. The sky's the limit (well, aside from your wallet).

thank you for the info but how do you know that the engine will have that kind of mileage that you mention. and how much power can the bbdet can hold without going inside the motor. sr20de can hold 400 without intenals. but the piston colling and lower compression does sound very good. can any of those options that the bb have could be used on the sr20de?

jgy sometimes has bb motor with out the turbo setup for cheap (like 900)buy it with out the turbo and look for a gtir t-28 kit (andrea mlinko has one one the for sale borad )or put one to gether your self. but the cow boy is right get a det:cool:

YEAH I MAY GO with the bbdet. the fmax kit stage 2 is about 4500 dollars dam!!!!! it wasn't so bad but that does not include the jim wolf ecu witch is about $595. so i go with the det for now and upgrade the turbo later on i will hate to buy a fmax then my motor dies good looking guys!! i didn't know that the bbdet came with such features i guess its worth ripping out your motor.

I didn't know the BB came with oil squirters for each piston I thought that was for the GTIR motor only

All DETs have oil squirters, all DETs have lower compression ratios, some are lower than others. A DE can handle 400 HP without going inside, and a DET can probably hold a little bit more, but is basically the same stuff inside, so at least 400 as well. Any good engine importer will certifiy the mileage on the engine to be "Less than 30k miles" or something to that affect.

An F-Max definitely makes more power out of the box, but costs lots of money, too, which is why I wondered why this thread was ever started. Have you ever driven an SE-R with "only" 200 wheel horsepower? It's a blast in and of itself; IMNSHO, F-Max systems are a lot of turbo; a lot more than most people considering a turbo swap/kit will ever need.

actually, the main thing holding both the DE and DET back are the cast pistons. both will realize about the same amount of horsepower.

And an FMAX stage 2 will, as frank found out, put down 380 whp on stock ignition. my T25 put down 250whp, and that was pretty much all she wrote.

250 whp is no longer enough for me. just watch, the HP bug will bite. my car now feels just as fast as it did before the turbo, you get used to a certain power level, and it will no longer feel fast, just normal.

i plan on upgrading to the DP turbo. hopefully it will last me longer. :D

You could rebuild your de as a det or maybe even better. Upgrade your rods to crower-they are much stronger than the det (pulsar) ones. Get the jwt pistons(which require bore work to the cylinder).
Or you could find a person who has already done this stuff to their det and get their parts from them.
Dollar for dollar you can't beat the blue bird det -as long as you get the entire engine/turbo/ic/wiring/ecu as a package. Soko was selling this for about 1400 including ecu! To me that is one hell of a deal.
I've spent probably twice that so far on my pulsar motor just to get a few extra ponies and some bragging rights. Screw the bragging rights and save some monie!
