anYone KnOw anyThing aBouT a Sequential Twin-Turbo SETUP>?

[spa01s2k]

What would you like to know about it?

[..:cOrNerIng ArTisT::::..]

this guy was just telling me that it would be the best setup for power without any lag like a Centrifugal supercharger or a single turbo

[gomarlins3]

Since I could actually understand what you typed this time, i will try to anwer your question. I do not believe a sequential turbo set up would work well on a four cylinder car. The turbo systems that are presently available for the S (LoveFab, Inline Pro, etc) are very good and do not show the amount of lag a typical turbo would on a V8. You do get more power sooner then the SC set-ups available for the S presently. You can also have larger gains overall with a turbo. The down sides are the up front cost as well as the tuning costs, but the upsides are SOOOO good.

what type of setup does the topfuel turbo s2000 have>?

They use a single turbo set-up (not sure which turbo). I could see a sequential set up being fairly good on the S2000, but would take up too much space. It would also be heavy, harder to tune, and way to much of a headache to plumb. I would have to agree with marlins, the turbo kits available are fairly good about lag (very little).

[..:cOrNerIng ArTisT::::..]

well its no fun havin a turbo that other ppl have a Sequential is something that i havenT sEen

[gomarlins3]

What's wrong with having one that you know will work correctly?

I agree. If you going to have a sequential turbo system, you are going to have to build the whole thing by your self. I know someone who turboed their S2000 that did all the fab himself, it takes a ton of time and patience to put together a system that works. Not to mention the amount of time it takes to tune the system. Luckily he tunes it himself so he can change things as the car needs it, not having to take it to a shop everytime something doesn't work right. But if you have the time and the money, let us know how it goes. I would love to see something different on an S2000.

[Scott]

People go turbo because they want to go fast. If you want a sequential setup just to look good, then go and waste your money doing it.

But odds are, you can't do the fabrication and tuning yourself. That means you'll be investing A LOT of money to have someone else do it. Or you can invest slightly less money (but still more than a pre-fab kit) and have someone do it half-assed. Then you'll still be unique, but make less power and have less reliability.

I'm not saying it can't be done. I'm just saying that there's no real good reason for it to be done.

[abe_fshr]

if you are going to go with a TT set up, install a small turbo then a medium or large one, you should have minimal turbo lag

[AtticusHasWon]

call me stupid but shouldn't you have at LEAST 3 exhaust ports per turbo?!? I have 240sx with a sr20det in it and i have heard people talk about twin turbo for that engine but it is only for looks realy!!! There isn't enough exhaust going through the tubes to get good results from a twin turbo setup, you'd be lagging like crazy!!! But then again i am new to s2k's so mabey it's different!!!

my .02

[MattG]

Turbos require exhaust gasses to pass through them to spin up the turbo (correct).

Turbo lag is caused by the engine not putting out enough exhaust to spin the turbo up to speed. Using a smaller turbo requires less gas to spin (due to lower roational inertia), and is suitable for smaller applications.

[AtticusHasWon]

Correct!!! But with turbos that small the only kind of power you would be getting would be in the low end!!! Which aparently is good for the s2k....but i think people might be let down by the performance "enhancement" they might think they will be getting!!!

All in all, it is possible, just depends on how you want to spend your money!!

this a twin turbo sr20det setup the forum that it is from is this: 240SX Forums .
read for yourself what a few people think of it FOR AN SR....it is gunna be different for a s2k but not much!!!

Remember when everyone wanted you kicked off of honda-tech??? Im sure it will happen here too

[abe_fshr]

why is that?

The guy is a tool. No one liked him. He asked the most dumb questions. He couldnt look any thing up, had to ask all of the time... Look up his user name

[s2000isu]

I dont think hes here anymore I dunno if he got banned or just stopped coming. I just dont like spoiled little ricers is all

i agree!!!

[gomarlins3]

I have seen him (at least I suspect it's him by the way he write) over on another forum.

[Hi_Psi]

why go with a twin turbo kit? that is retarded. you can go with a gt30 and have less lag than that of a gt35, even though i have been in a s2k with a gt35 with a slipping clutch and a exhaust leak and i was VERY inpressed. you can also get anti lag system with aem which will help spool your turbo faster than having to wait for it. its called the two-step, and when going standalone, aem offers it.

2-STEP AND ANTI-LAG ARE TWO DIFF SYSTEMS. You us the 2-step to set your rpms and the anti-lag to build boost. You can use the 2-step alone, with out the anti-lag

the two-step does help your turbo spool up though, works somewhat like a anti-lag system. i have seen a few supras with BIG turbos, gt47's mainly, who will get a 50 shot of nos until 10psi is reached, the the nos turns off and the turbo sings.....

I runover 28lbs on my car, I know about the lag also. I had a custom turbo made. Kinda like a t67 but the smashed the exhaust side into a t3 housing. I can flow alot of cfm but with little lag. The car make 460rwhp on pump and 14lbs, no head work

wow! see now you are the perfect guy i am looking for. someone with a car that has personnal experince! ok, as you can see im a newb in here but not with cars. i am in the market to buy a s2000 sometime soon, but need more research to know what to do before putting in a built motor. now i will be getting forged internals and a f22c crank to get a 2.2 displacents out of a f20c. also built the head to handle 10k rpms, and 1600cc injector to feed the cylinders with fuel. i am wanting to hit at least 550whp, but want to make 650+whp. besides clutch, what else wouold i need to work on? how much did you put down on 28 psi? you got pics of your car?

[gomarlins3]

You will also need to reinforce the diff or completely replace it with that much WHP I am guessing.

[s2000isu]

a two step doesnt really help a turbo spool as stated earlier anti lag helps turbos spool. Anti lag should change the amount of fuel youre dumping in and it adjusts your timing down alot so the turbo spools.

1600 cc injectors for 500 rwhp? You must only like running at 65% duty cycle haha.

Lastly I would hope a gt30 would spool faster then a gt35. I think a gt35 would be to laggy for a car like ours unless all you wanna do is drag it

thank you

i only want it for long runs. nothing more. in not going to the track with it or anything like that and it will also be a weekend car, a very fun one. but before all talk i need the car first. lol. and then i can decide what to go with.

1600cc not for 500whp, but will give me room for MORE. if i want to go with 600whp or even 700whp, i can just retune it for that hp.

You can click the link at the bottom of my page to see pics of the car and the last motor build. You can make 650rwhp but you will need $15-20k The only thing that is still stock in my car is the crank and trans. The gears for the s2k are $4k from PPG. You can go with the InlinePro turbo kit, I did, or get a custom one made. Inline is one of the cheaper ones but still is damn good. Heres a list


Turbo kit-$4000
diff kit-$3000
AEM-$1500
built motor-$5000
Ti retainers for the head-$500
injectors,1000cc- $400-500
FPR-$300
Labor-$2000 + or-

So thats $16700. add $4000 more when the trans goes

i figured that. a used s2000 goes for @ 15-18, plus the 17, @ 32-25k, where as my dream car(toyota supra) will run for almost that same price, stock. lol. and i would not want anyone else in the car except me and the gf on weekends.

you are not on a stock clutch are you?

cool. so your tranny was able to handle all the tq with 28psi? damn that thing can hold. lol. so is this still the 1st tranny? do you know about how much tq can a tranny handle safe? no strip remember that, just long run pulls every once in a while and weekend granny driving.

I made 300wtq on 14lbs. I have replaced 1-4th gears. They were bad from Honda and I wasnt turboed

[Hi_Psi]

well i guess i will need a fully built CAR. lol. fluuy built trany AND rear. pretty much a race car.

AS YOU CAN see in my pics my car is a race car but I still drive it on the street. The cage will be in it soon and I will be breaking this motor in. My first race is in Nj at teh end of next month

[Hi_Psi]

damn bro good luck with your race. i want my car for weekend use only, and maybe daily driver for a month every once in a while. but from what i am being told by you, 20k should make the car run good, with no problems, with 650-700whp.

awesome. i dont want to go all out like you, just wanna have a very strong car to pull crazy on vettes, mustangs and a few gt40s i have seen @ in houston. nothing too fancy.

[s2000isu]

which track in jersey? I have raced at Atco a bunch. Ive only been to englishtown and maple grove for swap meets and stuff.


edit: a 2 step helps you spool????? How does a 2 step alone help you spool. It wont make your egt rise enough to get a turbo spooling not a large turbo atleast. The timing needs to be changed as well setting a rpm limit isnt enough.
