whenever you go to a bigger turbo you will always get more lag. slides turbos are bush bearing so you get a touch more lag than a ball bearing, but once they are spooling there is pretty much no difference.
it isn't really much trouble since there are nice people like slide who do the hard work for you. you just have to unbolt the old turbo and bolt up the new turbo.
cost wise slides are about half the price of a new turbo that will deliver similar results.
then there is the problem of having to alter dump pipes, oil and water lines for different turbos.
i agree that it is all about driver skill and tyres. my mechanic has a stock sr20 powered sigma (weighs about the same as a silvia). it just has a cooler, exhaust and 15psi on the stock turbo. he ran a 12.56 @ 106mph, and a 12.9 with a broken axle. his 60ft times are usually in the 1.6 to 1.8 range.
i'd be looking at the window motor. i had to change 1 in a mates 180sx. it sort of worked when he got the car. then it stopped working. then it started again. then it just stopped. put a new motor in and all was good.
be worth checking the wiring first to make sure that it hasn't just had the power wire come off.
does that mean that you've given jmac a copy? if not then you should change your post to say that you will share with anyone that hasn't made you teary eyed.
and just because yours makes the heater in the mirrors work, it may have had some wiring changed to make it do it.
my mate has a jasma muffler that was on his car (so i don't know the exact brand since jasma doesn't seem to be one) and it splits into 2 sections in the rear muffler. flows well and is super quiet.
i have another mate with a straight through jasma muffler and it is quiet but not as quiet as the split one.
they class the rb26 as a 2.6L (2600cc) but it is more like 2597cc or something like that. it isn't the full 2600cc. no engine is as much as the quoted size.
the old 4.0L patrols are actually only a 3695cc.
i think someone needs a cookie, dude. you seem to be acting all high and mighty in these 2 posts, dude.
see now if you weren't such a stuck up dude, dude, you would've posted up the translation so all us other dudes could view it.
dude.
when i got my car the gauge didn't work and it was just due to the hose being split. i just cut some of the hose off and stuck it back on. that lasted a few days before it did it again, so i spent 40 cents and got a new bit of hose.
i have a hybrid fmic, turbo back exhaust (ebay dump pipe, 3.5" cat back), pod, stock turbo with turbotech boost controller and i hit 14psi in 4th at 2700rpm.
it is an insulation foam. designed to reduce temps. but since the stock airbox is plastic, and plastic doesn't conduct heat that well, it is of little use other than to keep induction noise down.
i'd remove it. it is probably also slowing air speed down.
when you change gears quickly the bov doesn't have much time to dump air, so there isn't much of a pressure loss in the piping.
i'd possible point the finger at the boost controller. the air between the controller and the wastegate isn't able to escape fast enough, so the wastegate is still partly open when you get on the gas again, so you have less boost until the wastegate is fully shut.
i also use a turbotech controller and i prefer it to the turbosmart one i had.
where you have the wastegate reading from can cause some spiking. if you have a fmic that didn't use the stock cooler piping then you should have a nipple inserted into the pipe from the turbo to the cooler. this will stop a bit of spiking.
all we were saying is that the mirrors weren't the only thing it controlled, as the picture looks like a windscreen.
but then you go and read through other posts peolpe have made and act all high and might about it, and act like the mirrors are the only thing it controls.
what r33silvers2 is saying is that when he gets on the gas after selecting the next gear the boost sits at 0 for a bit before it starts building again, instead of going pretty much straight up to the boost it is set at.
on gear changes the gauge should go into vacuum.
