s256 Questions?!!!!

[starscreem]

hello
Well i bought my self a s256ett the other day and had a few questions that i could not find a direct answer for. my mods are up to date in my profile also.

1. What size injectors should i run on this as i figure my denso 660cc are to small.

2 What kinda oil feed should i use, from head or filter housing. also what is the in thread size as i was noticing on web sights it looks like bullsye has its own. only kits i could find were from extreme psi that had a bullseye selection on feed and drain lines.

3. Should i run a inline filter and restrictor on the oil feed.

4. Has any one had any problems with fitment on the map recalculate mvs o2 housing.

and anything else or suggestions any one can think of would help a lot!!!


Thanks
Matt

1. What fuel are you going to be running. I have 1600cc injectors and im seeing about 80%idc on E85

2. Feed from OFH, no restrictor unless pressure higher than 100psi. I have the extremepsi feed kit it works great

3. Filter is not a bad idea I am running the earls.

4. I am using the map recirc 02 with mvs and it fits perfect. I have powersteering and everything.

I have about 1500 miles on my S256 and I love it.

well im still not sure if i wanna do the e85 swap yet. i plan on running 93 or 100 octane as i can get those both with in a few minutes from my house. i can get 110 octane but have to drive about 25 min.

 

[cyclonekid77]

For pump gas I would recommend a set of FIC 1250's.Big enough to max it out and some room to grow.

 

[starscreem]

ok just wondering how much boost could i run you think on my 660 densos tell i pick up something bigger?

 

[biglady112]

Around 20psi if you do it right. Those 660's will get you down the road and help work through your issues until you can afford a properly sized injector.

 

[starscreem]

Thanks for the info, i do think 20psi is a little high but i really don't know so ill have to see what duty cycle looks like after its on. well i got a few parts in today and just wanted to update u guys.

1. -10 oil drain line set for the s256 and mitsu oil pan.
2. -4 oil feed line from off the oil filter housing with a earls in line filter.
3. fp 4 inch intake none recirculate.
4. black tial mvs wastegate.

I have a buddy that's pretty good at welding and wants to make me a o2 housing like map and punishment make for non recirculate. Here is a link to some of his work if you wanna see what he can do. Lude Technica ».

and here is a few pics of the parts i got !!!

I am running this turbo on my 2.4 build here: http://www.dsmtuners.com/forums/cylinder-head-short-block/389989-my-2-4-build.html

I used the BEP restrictor fitting at the turbo and run a -3AN line from the oil filter housing. This was the suggested configuration from Bill at BEP. I am using a MAP 38mm recirculated housing and there are no clearance issues with anything.

The new head should be done soon so I hope to have some dyno/track results soon.

For pump gas, I would recommend a set of FIC 1250's. Big enough to max it out, and some room to grow.

When I spoke to Bill Devine, he explained the meaning of the S256ET's oiling recommendation sheet (below).
He said:
1) to use a -4 AN oil feed line, from the OFH, with a pre-turbo inline oil filter;
2) concerning the restrictor, the "if" relates to whether I choose to have FP (Forced Performance) sell me their Black Inline Oil Filter machined to 0.080" (instead of its normal 0.030") which he recommended most, or to use a 0.080" restrictor at the turbo's center section;
3) to use a -10 AN oil return line; and
4) to use an aftermarket oil pressure gauge to monitor the oil pressure.

Since you have an Earls inline oil filter already, Bill's explanation leads to using the 0.080" restrictor at the turbo's center section.

I do not know about the spring pressure of the MVS (Tial offers combinations up to 24.66 psi), yet cyclonekid77 has skills, and he could chime in to explain his wastegate setting. I imagine he added an MBC to reach enough boost to run a 11.4 sec ¼ mile. I mention this because I use a PW39 which came with springs to reach 26 psi. I have been running the 20 psi spring combination while breaking in my engine, and I am changing it to the 26 psi combination this weekend. When I added a crappy MBC to the 20 psi spring combination, I unexpectedly spiked to over 30 psi, but what a huge difference in the turbo's pull and sound. I immediately removed the crappy MBC due to the spike, and corresponding knock, yet I realized that 20 psi was not giving this S256ET any justice. I'll get a quality MBC for the future.

ok i will look in to the restrictor for the center cartridge. also i guess i forgot to add to my profile that i do have a aem tru boost so i can count the MBC covered. i do know that i put the 1 bar spring rate in the tial to start off with witch is 14.5psi. i will just turn my true boost off tell i get her dial in at the boost.

thanks for all the info guys!!!!!

 

[VETDRMS]

Just for reference, if you use a 3-port setup on the wastegate you can run much higher boost levels (stable) with a lower pressure spring. I currently have the 7lb spring in my wastegate and can run 25psi at only a 60% BCS duty cycle.

I have my MVS wastegate set for 1.4 bar (~20psi) and I am using a Buschur inline boost controller to get it up to ~32psi+ from there. This turbo really comes alive after 30psi. Rite now I am having a problem with the boost tapering off as I go threw the pull. I start out at 35psi and buy 8k its down to 30psi. I am running my vaccume line to the bottom port of the wastegate but I may move it to the top port to help hold the wastegate shut.

This turbo really is a great choice for the street today. I took it to buschur's today for there friday dyno day and here are the results. I was REALLY hoping for 500 at the wheels, but I am close and I think I may still be able to achieve that goal with the some tweaking but the setup is pretty much maxed out i'm thinking.

Anyways, here is the dyno sheet. Mods are in my profile and up to date for the most part.

I'm considering ditching my holset for one of these. Can you share some details on your timeslip. What was the date? How was the weather? How was the track? How much boost? What was your tune like? Was it the same power as your dynosheet? ect...

 

[starscreem]

no i do not work at sears!!

so the fitting i got in the kit from extreme psi did not come with the restrictor fitting i take it then, it does look just to be straight through can any one verify this and if so were can i get a restrictor for at the cartridge. i am trying to get this on by next Saturday.

 

[jnf63]

The easiest method to check your fitting is by using a 5/64" drill bit (0.078" being close to 0.080"). If the orifice is larger than the drill bit, then the fitting will not act as a restrictor. One of the Bullseye Power technicians told me that a reputable machine shop could fabricate a restrictor inside a fitting like you have by using a 5/64" drill bit. I do not remember the complete explanation of this budget (and quick) method of making a restrictor because I have the FP filter acting as my restrictor. I believe B.P. sells a restrictor that fits in their center cartridge. I suggest that you call B.P., and ask them about the best (and quickest) method to accomplish fitting a restrictor in your turbocharger, because they were helpful for me.

Coincidentally, cyclonekid77, those dyno numbers exceed what the salesman told me to fantasize for a maximum Mustang Dyno reading, he estimated a maximum of 410 AWD WHP. Your accomplishment is awesome!

Not sure of the date honestly. Early July. It was around 85-90 out and sunny. I was on crap tires and not getting good 60ft times. The boost was around 28psi because at the time I was having ignition problems. Tune was aggressive like always

The car was definitely not making the power for that pass that it is now. Im looking for a 10 second pass this weekend at the shootout I will let you guys know if it happens.

no i do not work at sears!!

Im running the same oil feed setup exactly how it came from extremepsi. 1650 HARD miles on this thing so far and she shows no signs of quitting.

Thanks Man! I was really hoping to reach my 500hp goal but I can't complain about the numbers at all. The thing I really like about this turbo is it is good for just about anything. I auto x on it no problem, its a total blast on the street, and I have no doubt in my mind that its good for a 10 second slip. In a light car this thing would be even better. Remember, my car weighs in at 2970 without me in it so in a lighter car I could see a mid to high 10 second pass no problem.

 

[starscreem]

well i just wanted to give you guys and gals a update on the turbo install. here is a few pics of it so far car is running just no boost right now due to the stock o2 housing, but im going over to my buddies tomorrow and he is welding me up my o2 housing for my mvs!!!!

 

[starscreem]

well i have a new question for you guys and gals. what clutch do u think i should run on this turbo? the reason i am asking is i just picked up a awd that im going to swap my hole set up in too after i get it running. well when i got it i was told the clutch is bad and the one in my gst is also starting to go. since im going to be putting the gst back to stock for my girl ill just get a stock disk or a act street disk. so what clutches do you guys think is reliable and will hold the full potential of this turbo? i dont want a twin disk i have driven one alot and not a big fan, i am scared of act pressure plates from all the failing posts i have seen. i had a spec stage 3 for my old prelude and loved it. so any info you guys have would help a ton.

thanks again

Matt

 

[bme91gsx]

I ran an Act 2600 when I was 5sp, on the 56.

 

[starscreem]

well here is a update again. we have finished the o2 housing but changed plans and decided to bring the dump back in on the down pipe, so we have a few more things to order but here is a few pics of it on and dumping to atmosphere.

Setup looks great, your friend's fab work is pretty good as well, his stianless work looks great (was browsing his site) Maybe uses a little too much head on some of the connections between the piping and flanges but nothing that would comprimise the integrity of the materials (i love fabbing with SS, it loves being welded with about the lowest amperage you can use)

What RPM are you seeing full boost by and what is your peak boost set at? (i saw mention of 20psi because of your injector size but didn't know if that has changed yet) I have some nice 1000's to sell (trying to get some 1600's ) if you're interested in some FIC 1k's

I'm really up in the air on turbo selection right now and it all mainly depends on what i can sell the 2 I have for in the end but the borg warner turbos are really starting to look apealing to me. I'm not so crazy about the bolt on mitsu style housings but i'm sure i can get them in about any flange i want at this point.

Update us on the progress with this turbo as you go as i'm really interested in knowing both how it performs in general and how much of a difference it makes when you re-route the wastegate. Since i can tell your fab guy is good at what he does i think i could safely trust that the results of your setup compared to mine would be very very similar in the end. I keep saying i'm gonna finish and install my down pipe every morning but always run into hangups for some reason or another, but now I might just wait on your results.

 

[VETDRMS]

Wow, I don't know how I missed this thread. I am always scanning for S256 stuff.

I've been very happy with this turbo on my 2.4, just got it on the dyno tonight:
