gt2871r .64




ARP head stud kit



Cosworth metal headgasket




N62 maf




still waiting on the turbo lines and injectors

[Speckid4]

Nice job, Is this your DD? I do like the interior. Making that brown disappear im sure is alot worse then the gray in my 95 was. I hope you used lots of spray on the carpet cuz if its a DD like mine then some of it will rub off no matter what.

Keep up the good work!

thanks, and no its definatly not my DD

and yeah the carpet does slightly rub out, but not bad at all... hardly noticable, but i plan on buy brand new carpet after this little build im doing now

[badbob2121]

well i got my deatschwerks 740cc injectors in

and im still waiting on my turbo lines... i guess some distributors dont believe its important to mention their parts are on back order

but they should be delivered on tuesday, and im bringing my car to my buddies shop next week and the tear down begins

the injectors

[S13AL]

I feel your frustration with those back orders. I've ordered turn signals at least three times to have them back ordered.

[badbob2121]

so the turbo lines are in...





so ill have some build pics and atleast a dyno sheet or video from the tune here in the next week or two..

let the build begin

[badbob2121]

well the build is finished and tuned, very happy with the turnout... im still in the process of gathering pictures and the dyno videos, but it will all be posted here soon... crazy top end!!

Very nice. How much you putting down @ what PSI??

I made 280 @ 15psi so far. Need a return line with correct fitting and we will dial in a little better. Very conservative tune right now.

[badbob2121]

Well ive been really lazy with this update

tuning went pretty well, the guys at specialty Z did a great job. Had to put in a new 02 sensor and ended up buying a new turbo outlet also

the car put down 291 whp and 267 ft.lbs/t @ 15psi on 91 octane

i had him alter the tune for 93 octance since i am moving back home to st. louis, mo next week and can stop running the sh*tty CA 91... i will turn up the boost to 17-18psi and should push another 15-25 whp out it

dyno sheet



and a dyno video of a 271whp pull

the car pulls so much harder, especially on the top end...

[Midwest_240sx]

Badbob, I'm in st.louis. Hit me up, I would like to check out ur car, my number is on the side. Where in the lou will you be staying?

[badbob2121]

alright sounds good, im going to be staying in west county (kirkwood) temporarly...

i have alot of buddies that are s chasis owners there, we could get a meet going

[S13AL]

290 is a very nice amount of power. The car looks clean in the video too.

[badbob2121]

290 is a very nice amount of power. The car looks clean in the video too.

definatly, esspecially with stock cams.. there is plently of more power to be made.. but this is plenty for now

next i am gonna focus on brakes

[badbob2121]

Well i am offically a free man and moved back home to St. Louis. Its great being out of CA and back in a state with no required emissions

Ive been going over and cleaning up the car. I encountered a problem since i changed out my ecu. The ignition start wire wasnt getting the full 12v, so the car was having really bad cold starting problems...

it was an easy fix, i just picked up a 3 wire on/off switch and spliced into another power wire and wired it to the ingition start wire and bam...just flip the switch before a cold start and she fires right up

i also picked up a Covercraft NOAH cover for when my car is ever stored outdoors which is a great cover that has great protection in all weather conditions.. i picked it up from summit for around $200

a few random pics for the other day

I'm still waiting for my coils after two months, thanks intensepower! (I did save a good penny though but still)

[badbob2121]

Another Update coming soon...



still hunting the ups man...

[badbob2121]

Well i got in my Hawk HPS brake pads and everything went well with installing the rear brakes, but when i got to my fronts i found that the company i ordered my brakes through sent me the wrong brake pads... so im in the process of an exchange..

but the rears are finished...

Heres the old setup


here the new




old compared to new



the rears feel noticably better

[Midwest_240sx]

Hit me up tomorrow(later today) Still wanna check out ur car.

[badbob2121]

Hit me up tomorrow(later today) Still wanna check out ur car.

there is actually a meet every thursday night my buddy just told me about, apprently there are over 60 cars and was around 10 s chasis's there

if the weather isnt crap, ill probably go if you wanna join?

[badbob2121]

well yesterday the CORRECT hawk hps pads came in, so this morning i did the install. everything was a breeze and i actually barely broke a sweat doing them... the rears were a different story

but everything came out great, the new rotors and pads feel great and made a very noticable improvement actually





i actually just ordered a Godspeed catback to change things up a bit, straight pipes are nasty and i will surely be keeping them... just something to change out when i get bored

ill post up pics and maybe a sound clip of each catback

[badbob2121]

the new catback came in. the quality isnt bad at all, i was actually impressed.

i bolted the axle back pipe to the isis mid pipe (no resonator) and it sounds very nice, deep and has a nice tone

the mid pipe that came with the new exhaust has a resonator, which is what im going to use with the isis straight pipe to keep down the raspy tone straight pipes have

its nice having a choice...

[xiaphin]

Nice numbers. You find out what the numbers were with 18psi? I have similar setup and hit 303whp and 287tq at 18 psi. Running stock manifolds, intake and exhaust. Link to build in my sig.

ive been following your build for a long time, nice work

i have not put it on the dyno since the ive been in st. louis and been running 18psi on 93oct, but it pulls noticably harder than it did on 15psi and 91oct

but im sure its a little over 300whp, similar numbers to yours, and thats with stock manifolds, block and head... so theres plenty more power to be made if i want it

[Lobo240sx]

Both of you have very nice setups. Good numbers for a stock block

What is the turbo efficiency for the 2871R? Can you go past like 20+ psi?? You can make plenty more power with some head work.

My T70 is rated at 29.6psi.

[xiaphin]

What is the turbo efficiency for the 2871R?

Was wondering the same thing. My turbo, the FP Big 28, has been pushed to 22psi by DSM owners but most run 18-20. There is no compressor map for mine all i know is that it flows 550cfm. Any idea what the GT2871 flows?

[badbob2121]

heres the gt2871 .64 compressor map i found on garret's site



i know the gt2871 can be pushed well over 20psi

[badbob2121]

the car has been running great, so i took it out and snapped a few pictures








im thinking about getting a whole nrg setup (QR 2.0, short hub and wheel)

well see

[420sxWETDREAMS]

looks really good BADBOB
