Spec V, first build, about $1000

Re: Spec V, first build, about $1000
nissan should just stop ------- around and drop the vq35 in altima trim in, and toss the qr20/qr25 out the door.
needs a ------ cvt turbo, someone go build one. i wanna see what that trans will do when you hold rpms at 6500 the whole way until you let off the gas at the end of the quarter.

Re: Spec V, first build, about $1000
this is one of the funniest threads i've read in a while. JD, what do you do for a crust irl? i'm curious. when reading up on my holset purchase months ago, i came across your posts in the big honduh thread. i cant remember why i remember who you are, but i wish i could :-)
keep up the funny stuff.
my only comment on this thread is that yes, all manufacturers are making their bearings smaller and their rods weaker in more modern engines for a fore mentioned reasons of economy and emtions etc.
sr20 bearings are pathetic and you dont need a turbo or higher redline to ruin them. i have changed several sets myself.
thats probably the best part about my motor, its strong as all hell.
middle aged motors are the best around for mods. mid 80's to late 90's or so. rb30det is my next big hp project when i get back to the home land where my toy is. stuck in england for now and a while. the rb can be built strong for cheap and make big power easily. i might even swap the holset across to it and put something more sensible on the fe.

Spinning through the first three gears may be a good indicator of power to you, however it tells me maybe you need learn more about suspension setup and how weight transfer in a FWD car is a BAD thing for traction. Doing nothing to adress it is even worse. laying in to the throttle still causes the tires to chirp and fight at the top of second, if it wern't for my suspension setup it'd just light them up.
If I leave hard and shift hard I can make investing in tire company stock look like a good idea, especially because the factory LSD is a good unit, but just through 2nd. I still owe 8K on the car, so running it hard just to impress someone is stupid and childish. Running it hard so I can make changes and satisify my goals for my car is somthing else all together. My goals existied before becoming involved with Treadstone. I could just be another idiot who thinks spinning = power. After I get some dyno numbers, I think some (probably just a few) on this site will be impressed with a lowgeared 6 speed high WHP and TQ FWD car actually maintaining traction, but not by the virtue of Nissan's design, rather than... well maybe you get the idea. I've got a few more spring rate and weight distribution combinations to try as the first few changes worked like theory said they should. I still have to couple straight line traction, drivability, and cornering to work well together, because this is the goal of a well balanced car and a goal of mine.
The pulls were on a peak boost of 4 PSI, the peak comming at 5K with a jump from 2.5 PSI. It's not creep or a design issue, it's the type of boost controller used, and an inability to function well with pressure that low. At 8psi, it's fine, stable boost, 8 PSI from 2800-3000 up. 4PSI peak boost is much faster than any NA spec V, end of story.

But the 1K I dumped in came back to me by fabbing the prototype SRT-4 downpipe for Treadstone, plus the new setup (all the name brand stuff and bling) only cost me shipping on the prototype mockups I mailed Treadstone plus the time I invested. You don't even have to factor in what I sold my old parts for and I'm ahead of the game...........
There is a big diffrence between 2.5 peaking at 4 and 6 PSI, lol.
And the spinning tires thing, read my last post.

Re: Spec V, first build, about $1000
i agree that 3.5psi is a lot faster than na on mine. when i first had mine running, it was with a valve spring on the wrong side of my modified and now quite sweet chinese wastegate holding it wide open all the time. just the nice inlet mani and a gentle breeze increasing to 3.5psi by 7k. it felt quick enough and would hold wheel spin in the wet to 120kph redline in 3rd with no issue at all. from the injector duty cycles in the ms logs, i estimate about 190crank bench hp with the wastegate open and 3.5psi blowing through. for reference, the motor makes 148ps with the stock cams i have in it, so it is a lot better in the upper rev ranges with a bit of a helping ve hand.
as for giving it a bit of ----...
if its not built to handle a proper raping, then its not built right. thrashing it hard is a non issue if you have done your job right. the only question is whether to bother taking and posting vids for a web audience that will forget you soon enough. personally, i like it. but saying that its doing the car harm is not at all right.
are those engines DI ?
