Idaho Tuner's 240/|SR Build thread

[sbird1]

That was a sucky update. At least make something better up. Put some effort into this thread for god sakes.

[White Comet]

^ lamo, yeah just tell us lies for updates. we'll still listen

[idahotuner]

lol.

well i am watching a couple of ebay auctions right now as well for HKS BOV and hot pipe. so if i can get those that will be sweet. save me about 200 dollars too.

so keep your fingers crossed. and dont go out bid me now lol.

and and the deal with the ECU is real not a lie.i emailed scott and he said to run the tuned ecu how it is until i get it dynoed. and then take the a/f chart and dyno chart and mail the ecu in with that for a reflash.

so looking like i might be able to start my car sooner then i thought. we will see

[redtop91]

Do you have any............POTATOES?!?!?!?!?!?!?

[idahotuner]

haha no potatoes

but mashed potatoes and gravy and elk steak sounds good right now

sweet man thats awsome

[idahotuner]

well guys i gota good up date today.

no i didnt work on my car lol.

but i wo na HKS hot pipe with HKS BOV SSQ for 137 dollars off ebay.

and i got approved for an 800 credit line. so once i get my card i will order a greddy intercooler from ask me for parts .

and then i will get my intake and cold pipe from piping pro.

it will be bad ***.

oh and i am gettign my ecu on monday. well going to buy it.

so after that i will only need injectors and radiator. and i can start this mutherfvcker up

[Didderson]

Wohoo! Nice man. I'm glad you updated it lol. I was getting fidgety not knowing what build threads to check.Great price on that hks stuff. My hks bov hasn't let me down yet, after I figured out how to install the sucker that is lawl.

[codyace]

Credit Card build never!

Don't do it man, it will just become addicting! You've come this far, you can wait it off just a bit more and pay for it normally....heck it's still mid winter! Save that credit card for emergencies, and you'll be set!

Now make sure you get the recirculating bung for the BOV and you'll be good to go

Oh and PS: Speaking of intakes, you'll only need a 45 degree silicone fitting from the turbo to the pipe, and then to buy a 45" bend from Kteller or similar and you'll be set Look at my gallery to see how I did mine.

true, a lot of what u say is correct, but ur very condescending. i dont feel like arguing anymore about the spool time of the t25 and the gt2871r, maybe later

Has this been enough time? There's nothign to argue. The 2871r spools no where near a t25. Never ever ever, unless you'r running like, wacky timing on a 2871r car, and even then it won't.

And condescending is all in the eyes of the beholder. If you don't like un sugar coated advice, I dunno what to tell you.

[Hijacker]

sounds like youre doing every thing right. just make sure your tune is right. over 20lbs of boost can destroy internals. hence A/F, and timingbelieve me, i learned the hard way. stock pistons have weak ring lands

Tell me about it....This was the #1 piston in the blown block I picked up for a rebuild.



That was probably the worst looking piston I've pulled out of a blown SR

i dont nderstand then how a ball bearing turbo wont spool as quickly as a stock t25. ball bearing is just aobut the closest to frictionless as u can get. less friction = faster spooling.

[Automato]

well in the end, i think it comes down to compressor/turbine combination. the smaller compressor on the t25 will make up for the journal bearings when compared to a bb t28. if you compare the journal bearing GTIR t28 to the s14/s15 bb t28's then you will see a difference in spool time. i also think that the spool time between two identical, journal bearing vs bb, turbos will be a small enough difference that it wouldn't matter. where the ball bearing shines is throttle response.

While the above post hits a few points, I'll continue with a few:

1. The most important (again as above) aspects in determining spool time (in regard to the turbo itself) are wheel design/weight, and housing a/r. This is why a .64 housing 2871r spools much quicker than a .86. Same can be said with T3/t4s when you compare a car with a .48 to a .63 (or larger)....

2. Ball bearings do speed up spool, but it doesn't make it instant by any stretch. With your 'frictionless' example, you could then say that a gt35r would outspool a t25, which is never ever ever ever going to happen. Heck most t25's run out of steam by the time a 35r is even full spool heh. Even with a frictionless (which it isn't) you're still goign to fight some drag, and some resistance.

3. You also fight boost onset, which is commonly IMO confused with lag. Some cars simply feal sluggish in response, even with a fast 'rpm' spool time, and vice versa....some cars just ramp up very slowly into boost...drive a stock wrx and you'll see what I mean. Granted you can tune some of the onset out of a setup, but not to much

4. Have you been in a t25 and or in a gt28 car? You'd certainly see what I mean.

[idahotuner]

Credit Card build never!

i have the money. the reason for this is to build credit. so when i graduate from college i can buy a house.i pay it off at the end of every month to get the benefits and none of the disadvantages

1. hmm ,thats something i hadnt considered, good point2. reread my post, i never said it was frictionless, i said its CLOSE to frictionless. unless something has been discovered or invented that i miss (doubt it) ball bearing are as close to frictionless as u can get3. yeah i aware of the difference between teh 2, ive driven multiple turbo cars4. never experienced a gt28 but i have a t25

[idahotuner]

so we know that if there gt2871r was non BB and we compared its spool up time to a bb gt2871 the bb one would spool up quite a bit faster correct.?

[mrgreeneyes]

why does all this actually matter? he has his turbo of choice, so this means nothing NOW

[idahotuner]

thanks buddy^ true that. it will hit boost plenty early and give me more then enough power to get in loads of trouble.

[2LO4URHO]

Good to see your making good progress. I haven't done much lately haven't had much time and it's been cold as sh*t. Plus gotta spend some money on the bike to get it back in shape. Maybe, one day we'll meet and race. With me on my bike that is. Cause you're building a beast!Im also working on a getting a classic right now so my hands are tied but keep it up man.

[sbird1]

This thread are teach Scott 'bout turbo, durrrr...

No, seriously. I R learning.

[idahotuner]

Cause you're building a beast!

Thanks.

I ordered my LS greddy intercooler from askme4parts. and hope fully i will get the ecu in a couple of days. i just have to call and remind the guy for pictures.

This thread are teach Scott 'bout turbo, durrrr...

No, seriously. I R learning.

LOL yea we learn something new every day. but this is my build thread so we need to keep it as a that lol.

[idahotuner]

Ok guys here is a real up date with pictures.

so we rolled both fenders on the passenger side and my dad fixed the front fender. frotn me sliding int oa bank before i parked the car to work on it.

I got the shifter installed the correct way finally. but when i did that the damn camera batteries were dead and i didnt feel like finding new one right then.my shifter installed with new shift knob my sis got me for xmas. sitting on itwe are shaving this body line to give the car a smoother affect and to help with the paint.here my dad is welding spots on the rolled front fender to make it srtongerhere you can see the roll.and here is the back fender rolled. we need to do it a little more still.here is some shots wit the fenders on and some body work done.i like this picture for some reason.ok here is a pic of the rust cut out on the rear deckhere is an interior shot.here are some shop picssome extra car parts i got for my nissan. and left over parts from my integra.

and some out door shots

the shop right nowour storage shed and my accordmy accord. see how high the snow is compared to itand our housethis would be our trampoline. which is normally 3 feet above ground, but as you can see the snow is 2 feet above it. do the mathtake a guess where this pic was taken. ok i will tell you that is me one our roof saturday morning doing what i did all day long. shoveling snow away fro m sky lights and vents.

[Didderson]

Holy crap man that's a ton of snow. I hope your house is strong enough to support all that snow on the roof. We've had warehouses roofs collapse over here sometimes. Then again you don't live in a warehouse.Build looks good so far. Quite a bit of body work going on. I'm jealous of ur insulated garage. Ours isn't insulated even tho my parents room is right above it.

[idahotuner]

the shop isnt that insulated that well. so it sucks especially with high ceilings. but that is why we have a wood stove.

yea we got alot of the body work nocked out. but we have alot more to do. i should say my dad got alot of body work nocked out. i dont do much of that. it is his thing and he likes doing it. i like doing little installs like the shifter. and stuff like that. lol. doesn't mean i dont help though it is my car.

as soon as my intercooler gets here we can get the front bumper set up. and then my dad and i are going to make some kind of diffuser/scrape guard for the front. custom made. lol. my dad lieks figuring out fancy little ways to make stuff work so it will be cool.

[Automato]

nice info. yes i was a little wrong on my info. i thought the 35% was just a ratio comparing the side wall to side wall to the heigth of the side wall.

you seem to be alot smarter on this. so i got a question. for 17X9 wheel. if i run a 235/45 would that be a good size for 9 inches wide?

/sorry tom for the thread jack/

hey, just wanted to answer your question. but i'll do it here so we don't clutter up tom's build thread. 235/45 will be fine on the 9" wide rims. it will be slightly stretched but thats how most ppl like it anyway right? but it also depends on the end result setup that you are looking for. i'm not sure if you have coilovers, but if you just want it to look nice and drop the car as low as possible, then the 235 would probably be ideal for you. but if you want your car to be more performance oriented, then i'd suggest going as wide as you can on those 9" rims.

with your current engine setup, i think you can make anywhere between 350-400whp on high boost. i have read about several ppl with about 350whp that can't get traction until half way through 3rd gear and these guys run on some 265's. i am running a stock t25 and dynoed at 277whp. i have 225/45/17 tires and on colder nights, first and second gear are useless. if you are looking to get as much power to the ground as possible, i'd shoot for at least 255/40/17 tires on the rear of the car. these tires should fit fine on the 9" wide rims and should still fit under the stock fenders with a roll and pull.

[tramp_drift240]

255's on a 9" will fit under rolled and pulled fenders?

mental note.

[brizanden]

daM lots of snow i love snow but we got like none in ohio this year. i wanna go snowboarding in ur snow lol

[codyace]

255's on a 9" will fit under rolled and pulled fenders?

mental note.

255's on a 9 shoudl fit with maybe just a roll with the proper wheel offset.

[homeslicej2]

Wow. That's a bunch of snow.

[tramp_drift240]

255's on a 9 shoudl fit with maybe just a roll with the proper wheel offset.

i know stuff about width and offset, just not so much about proper tires.

and when it comes time, im WANTING to have to roll & pull the fenders. ill have proper width/offset/tires for that though.

mmm.
