Ok.... i tried searcing, didnt help..... so dont flame too bad...

Can you twin turbo an sr20?..... im sort of a noob to turbos and im just not sure.... thanks and please dont flame too much

P.S. i even googled it and that didnt help... thanks again

Ok this is what we have learned about it,

Yes you can and it works, it is kind of expensive fabricating a manifold, This company Japancraft make the manifolds and sell tht turbo kits, I gave them a call and priced the manifold it is close to $2500 not too bad but little expensive for most, You can make your own if you can weld and have a good plan.

Ultimately it is not cost effective but if you set it up right the car will haul *** this japan craft car can boost 2.5bar and achives 880hp at max boost.

i had the same thought but with a KA motor... will it work the same for that?

silviasichigo

Yeah But with the KA you will have to do or have all of the fabrication done, it will take a lot more money to build the KA for that kind of set up. There has been so much R&D put into the SR the KA needs more time.

Personally I think it would be a waste of money unless your into uber jdm brownie points

silviasichigo

Hmmmm Yeah I think so too I can't see paying $5500 for a manifold and two turbos on a 4cyl engine to achive something you can achieve with a medium to large turbo it is something that BIG COMPANY had money to spend on and they are selling like hotcakes in japan nothing like a twin GT3037 SR pumping out 880hp to the wheels...................wait yes there is it is a single T88H 34GK turboed SR pumping out 1100hp to the wheels. Oh well people love to change, be different, do different things so I am not going to bash it, just not my style

This is all besides the fatc that it'll take all day for a TT 4 cyl. car to make boost.

silviasichigo

Not really with small compressor housing, good cam setup you will probably start boosting aroung the same time as a larger turbo the car in the pic above starts boosting at4400 and is into full boost at 7300, When I went to The TAS I talked with the owner of the car and company and he said it is very resopnsive. It IS hard to say (Guess) what will happen until you do it.

g3bio

it was just a theory im not personally going for 880 wheel hp or anything funky enough to push me faster than what im getting for the track in the summer maybe a single turbo just because but there are other upgrades before that. I dont want to die with 880 hp i wouldnt be sure if i could handle that much and where i live its no point anyway.

Badazz_240

good input thanks guys.....

so let me get this right.... the TT wont spool up any faster than a large turbo?..... if thats the case then ill just go with a built single turbo

for some reason i was thinking that a TT would spool up faster

soldierdude262

To kinda sum it up, if you're goin for a real high hp figure, like 880, a TT setup will be more responsive than one giant *** turbo pumping as much air as the two turbos in the car shown above. As usual the answer to a queston like yours comes down to what you want the car to be, a car like the one above would really be a ***** to drive around town. So if youre doin an sr20 swap and the stock turbo aint enough you can go ahead and get a different turbo to make your car beastly yet still bearable to drive.

Badazz_240

im looking for like 400 hp on a s15 sr20......

i found out from a friend that what i was thinking of was a sequential turbo setup, not a twin turbo setup..... any input on sequential turbos?.... if not then a mod can go ahead and close the thread

soldierdude262

I've been put under the impression that sequential setups are complicated and expensive, if your looking for 400hp an sr20 with a singel turbo can make that, however I'm little limited on sr's so if anyone who knows more about'em than me they should speak up.

Badazz_240

i really dnt know much about sequential turbos either, but for some reason i was always put under the impression that they were boosting lower and stronger than a single turbo, but he said something about the small turbo restricting the big one at some point in the high rpms which makes sense

look at the FD RX-7 it has a sequential set-up, the small one boost up untill like 4 grand then the big one takes over , but all the people that want high HP go for one big one, not to mention all the vacums you have to have to make it switch from the small to the large, the call it the rat nest on the FD, so you can imagine what it looks like.
