Very respectable man, good job. Should be a fun season this year when i run mine as well (=

02-06-2009, 09:31 PM
thanks. I think I might be able to hit the 12s but who knows.

I am also working on doing an s13 silvia front end. I got sick and tired of the pop-ups.

02-07-2009, 11:25 AM
very nice build man... you have alot of the same stuff I have on my build. What are you running for ECU?

02-07-2009, 11:30 AM
currently a tuned factory ECU. but will be going to stand-alone

leaning towards a Link Storm

02-08-2009, 10:56 PM
how much:confused:

02-08-2009, 11:01 PM
Its not for sale n00b

02-08-2009, 11:07 PM
are you keeping current wheels or looking for something alittle more baller?

02-09-2009, 07:47 AM
I will be going something a little more baller eventualy. but what I have isnt so bad for now. but my main concern now is the power-terain all go no show is better than all show and no go

03-01-2009, 03:06 PM
well after pondering for a week on why it wasnt starting found that the starter needed a better ground. so a made one.

therefore I have a Running built SR20det


And a coupe pics of the new front end.


now just need to sort out the idle and get fuel managment and its all good.

and put the hood on and miscelanious things.

03-01-2009, 03:12 PM
If you're gonna rock that bumper, Please get skirts, rear and better fitting wheels, Otherwise it looks awkward, IMO anyway..

03-01-2009, 03:15 PM
I plan to. when I get out of school and get it tuned.

bumper came with the front end. I dont plan on keeping it.

03-01-2009, 03:58 PM
Lookin good man. You planning on any sort of tuck for the wires? looks like a rats nest under the hood :nut:

03-01-2009, 04:24 PM
That intake gives me a boner, nice choice....just curious how those factory brakes are holdin up:rofl:

Very nice build thus far!

The way it's supposed to :thumbsup: Good stuff Ben

03-01-2009, 06:18 PM
give me a break I havent had a chance to wrap up the wires. it will look better when thet are all tied up but for now it was just there.

as for the brakes they are stoping me but I do plan on upgrading this year.

the catch can still needs to be plummed in.

thanks Mike when I said I was gonna get it to run this weekend I wasnt kidding.

03-01-2009, 06:19 PM
holy.. nice ride.

03-01-2009, 06:21 PM
You going to get matching skirts and rear bumper. Seems kinda like the front drops way lower to the ground than the sides and back...Looks awesome though despite that hehe.

Read the whole thread before you post. He already said he was.

03-16-2009, 05:21 PM
Dude that is sick,
Your doing exactly what i want to do if i get a 240sx coupe.
Looks like alot of fun,
Why the rebuild?

03-16-2009, 06:47 PM

I did the rebuild because in July 08 I was running into quite a few issues with the motor)

Such as: 1. Blown exhaust seals (I couldnt see out my rear window since there was so much smoke.
2. Extreme case of blow by/crank presure (was shooting dipstick out of tube and every tube off the valve cover)
3. Head Gasket

and I figured if I have to take it out I might as well do it right the first time. and not waste my time with shit parts.

Thus as you see it there.

06-02-2009, 10:04 PM
Update: New Fuel managment. Power FC. and dyno tune. 260whp. still need to work out a few bugs but time for update. and car drives way more reliably. for those of you who know how bad it was.

and new pics of the car. I can use that bumper I have before due to certain reasons. so I have a stock one on the car for now.


this one is my favourite.


06-02-2009, 10:46 PM
Nice ride, although i think you need a new set of rims. Sportmax 962's? :D

06-03-2009, 03:45 PM
only 260WHP ben? i thought you said you were gonna make alot more than this..:confused:

06-03-2009, 04:20 PM
Pretty weak numbers for what uve done. Sounds like u did something wrong. Stock sr20det with that turbo would do more.

06-03-2009, 04:39 PM

i'll bet its the boost pressure, what is it set at OP? you should be seeing almost bang on 300whp at around 20 psi even at our elevation.

06-03-2009, 04:41 PM
Check your timing and your fuel ratios.
I'd expect around 400.

06-03-2009, 05:12 PM
It's not the boost pressure. That motor wasn't built right. Afaik he was boosting 17 psi

06-03-2009, 05:31 PM
yeah something isnt right. I might have to talk to the machine shop about this. with the amount thats in this 260whp is not acceptable. it felt more powerful before the re-build

06-03-2009, 06:28 PM
What is your boost pressure? Its a 2871 right? should be seeing more than what you are. Ayman made 360 to the wheels at 16 psi with his gt3082. Pretty much same build as yours, minus the different turbo thing. What are your compression numbers like? Who tuned it?

06-03-2009, 06:43 PM
its a gt2871 .82a/r currently running 17psi.

I have just finished a compresion test
1- 139psi
2- 142psi
3- 140psi
4- 150psi

The tune was done at auto-dream.

06-03-2009, 07:16 PM
Maybe the shop pocketed your goodies ben!! haha jk...
yeah Ben I was expecting something alot more wild than
what I had previously experienced..gl with what seems to be a never
ending list of problems you run into..

06-03-2009, 07:23 PM
trust me I am not about to give up. I was expecting something way more wild. I will have to figure whats going on.

engine was up to normal operating temp?

Most say once there isn't a large percentage disparity between cylinders you're good.

the FSM should have what is the acceptable psi range.

06-03-2009, 07:29 PM
yeah I did check the FSM and brand new spec is 156psi. so I am withing the ball park. I figured as much that since the numbers arnt to far apart. They are in an acceptable range acording to the FSM.

06-03-2009, 07:32 PM
wow only 260 ben!? :(
I put 247, and i need new tune and clutch haha.
fix this shit!

06-03-2009, 10:11 PM
Your compression numbers are fine. You have a powerFC? Talk to Toma, see when he has time to dyno you. jesus...i got 240 horsepower to the wheels out of my stock block with 13 psi from my gt2860......so something isnt right.

Are you sure your CAS is set 100% correctly?

06-03-2009, 10:22 PM
how much did autodream charge you?

06-03-2009, 11:01 PM
who built your motor?

06-03-2009, 11:27 PM
New fuel management?
Other than pfc, was there anything else? New adj FPR?

I have a almost the same setup, but no block and head work, 2871 and I'm running 366whp, 140across 4 pistons.

the adj fpr is the only thing I see I have over you.
Check your timing, (cas/ chain) and make sure the crank
turns properly and not too tight. Cams should be at 8lbs
of torque.

MAke sure your fuel is what it should be, at approx 60psi
when at power, 45psi when idling.

You should be in the 400s

06-03-2009, 11:39 PM
just so everyone knows autodream did not build this car, the op did it himself. before anyone starts pointing fingers

962 kid
06-03-2009, 11:39 PM
I imagine it's all in the tune, the car pulled much harder before the PowerFC was installed and tuned. The chipped ECU and 14psi was making much more power.

06-04-2009, 12:37 AM
its not the tune, its the motor, clearly he didnt build it properly/up to spec

962 kid
06-04-2009, 07:18 AM
You're right, the car magically lost power when the chipped ECU was replaced with the PowerFC. As soon as that happened, the engine came out of spec. The tune obviously has nothing to do with it

06-04-2009, 07:49 AM
some cliff notes.

OP was running chipped ecu.
OP built own motor after toasting his.
OP broke in the motor.
OP bought power fc for tuning.
OP got his car tuned.
Car pulled harder before motor was rebuilt.

its nothing to do with the tune.

Precise built the motor...

Is Win a certified Apexi tuner?

You can't write cliff's notes if you haven't read and understood what happened first. The car pulled hardest after precise rebuilt it, before the PowerFC tune.

06-07-2009, 01:57 PM
I'm curious to see what the end results will be. Not cool of autodream to charge a substantial amount for the tuning with such poor results then not even offer any feedback as to what the issues might be. if it's a case with the engine however then there is nothing more autodream could have done.

06-16-2009, 04:27 PM
i was told nguyen at autodream had to fix a lot of shit before he deemed it ok for the dyno.

06-26-2009, 09:10 AM
Any update on this thing? I'm suspecting a tune issue as well. PowerFC is a fantastic device when you know exactly what you're doing...

06-26-2009, 10:05 PM
well currently I have replaced the CAS as recomended my auto-dream and I am currently pulling the engine this weekend to fix that dam oil leak. then once I get the funds i will arranged to go back to the dyno .

06-28-2009, 05:20 PM
Very nice. I like the pics and poses. Wish i could find a clean one like that around here, with all the goodies lol

08-02-2009, 11:07 AM
Update. I have finnaly got a chance to get some fun out of this car. So I took it down to the 1/4 mile just for the hell of it and the best I could get was a [email protected]


and I was getting anoyed with the paint on my valve cover looking quite ugly so I repainted it.


08-02-2009, 11:21 AM
Ah this was the 240 that smoked my stupid cobalt ss!

08-02-2009, 12:03 PM
atleast now you dont feel so bad. knowing what I have into it.

11-28-2009, 03:23 PM
finnaly got some new parts to improve and repair

my nice cracked oil pump


a few new parts Power fc boost controler, DIF fan controler, AEM Wideband, Autometer EGT gauge, and a replacement transmision.


plans for the car more boost and better fan controler setup. better monitoring equipment and being able to use 4th gear for driving.

01-07-2010, 02:34 PM
i've had many problems with autodream, i brought my car there 4 times to get it fixed apparently, paying atleast $400 a time, one of the repairs was $750 and they still didnt fix it, i paid them over $2000 :banghead: then losing hope in them i brought my car to alvin automotive paid $290 to fix it and they found out it was a wireing harness problem after i paid autodream $350 to wire my wireing harness while the swap was being done.

none the less, they gave me $300 back from the 2 grand i paid them

shadyyyyyy work, i wouldnt not recommend going to them, i would not buy parts from them, i would not talk to them, find someone else to work on your nissan.

btw it was a rb25det c33

my car would break down the day or 2 after i got it back from autodream every time

03-22-2010, 06:01 PM
its not winter if you dont do something to the car so i made some minor improvements. next on the list would be a new tune among other things maybe a low 12 in the 1/4

new brakes, suspension wheels and stance


and a pic of my two cars together.


03-22-2010, 08:51 PM
Looks hawt and sounds even better in person! Nice fitment and fender roll :rolleyes:

Big Update

well i had my exhaust system crack on me. so i had to replace it.

finnaly got the car retuned. it did 324hp at the wheels safely but was able to get a run in a 350whp but was nocking to much. So i may need to run higher octance than 91. I am considering methanol or race gas. The important thing is that it runs much better than it has recently.


now i have to go out and enjoy driving this thing.

Upgrade on the way: Spitfire coilpacks

07-06-2010, 09:14 PM
how about you change the pic in your sig?
still, sexy as always = )
the car not you.

07-06-2010, 10:01 PM
Cars looking great ben, that bumper fit great that you sold me. Cant wait to see this thing at the track. My parents took their RX350 in and did that washer thing you were talking about..for free :D

-Keep us updated!

02-15-2011, 06:56 PM
I decided to to a 5-lug conversion and I found some wheels that I like

I also am upgrading almost all my control arms and sway bars.
new motor lower profile motor mounts to my throttle body doesnt hit my hood. When I had it out to a track day I was having a few issues with my tachometer so I thought I should change that.


I developed a decent parts pile.

After I detroyed 3 sr20 transmisions I got fed up so decided to make a little change to a 300zx transmision which is good for about 1000 hp. when I chose to do that I needed a new clutch too so I figured I would get one that would be amazing.


I got a Spec twin plate clutch good for approx 1200 ft-lbs

Since I am adding a better transmision to handle my current power level I thought I would give it a little more.


02-15-2011, 07:37 PM

06-14-2011, 08:26 PM
finnaly a bit of update. Some good and some bad news.

bad news I blew up my gt2871. but I decided to do a small upgrade since the upgrade was cheaper than a strait across replacement. However I did get a few laps before the turbo blew up at race city.


and this it what happen to the turbo


and this is the new turbo in its box.


Since everything was apart I figured it was a good time to put the meth kit in.


and my new wheels for the track



Then once I got everything all back together I went to dyno to get everything all tuned up. And the result was 380whp on pump gas no meth. We ran out of time to tune the car on the meth. I am happy with the result. definetly a bit of an increase from 323 whp. The dyno tune was done by Toma who was great and very helpful. highly recomend him to anyone else who needs a tune.

06-28-2011, 11:57 AM
Sick build dude, are cars look sick in that pic :p

I should be able to give you a run for your money after my minor upgrades :D

02-18-2012, 04:55 PM
well the last track day back in september i have a problem develop with my water meth system. and it melted a corner right off my piston.

oldy enough it still made 90psi when I did a compresion test.

so I decided to do a re-build again but this time I am going to do a little bit more. I managed to find a stroker sr that had a spun rod bearing and just needed to get repaired. so the stroker is at the machine shop getting everything repaied.

I decided to install line lock for when I do the odd drag racing. I do have to Mickey Thompson Slicks sittingin my garage too.


The fender harness on this car just kept anoying me getting hit by the tire even with it relocated above the pinch weld. I went and did the over kill way.

this is the passenger side found most of the wire had to do with abs and automatic trans. which both of these no longer are in my car.

Here is approxx 75 relocated to the engine bay.


All bundled up

And I started mounting a few new parts


I aquired a new hood and started installing new hood pins


And that should be everything up to date

02-19-2012, 12:13 PM
Wicked build, subscribed. :thumbsup:

08-09-2012, 09:51 PM
new tires for the rear

a decent shot of the front end

driveshaft loop

Engine shot

gauge setup for now


Dyno Time had loads of issues with fuel starvation and ended up replacing all fuel lines, pump and new regulator. I tried a brand new tomei fpr and I have that fail after a week and now I have a Aeromotive fpr in there now and seems to do the trick.

The car has been off and on the dyno over the past 4 months sorting these issues out and finnaly got satisfactory results

here is a pick just before it got towed to the dyno the first time.

shots on the dyno


The good stuff

08-30-2012, 01:17 PM
Mmm I like that dyno sheet :thumbsup:

before I parked it for the winter I had to confirm line lock worked properly so I left this on the side road.

Then I came across a change to make a huge change to the interior so I did.

well I finished building my custom fuel system and finally have a single color on the car.

Here is the car as it sits as of a week ago. when i took it for its first drive this year.
