im guessing the twin scroll 16g will out spool a standard evo3 16g.

Im wondering if any other small twin scroll turbos exist? I am looking to do a low boost application because its cheap (bandiad and wideband type build) and I dont know if i can: 1)afford megasquirt, or 2) if i can get a hang if the megasquirt thing---as i said im a greenhorn to this turbo thing

with that in mind, can anyone make an estimate of what power would be at with 8psi out of the evo8 turbo on a 1.8L

you guys do realize that the evo 3 is the only off the shelf 16g that will work for us guys running a normal 16g setup right? the evo VIII is a different inlet design
Evo VIII


Evo III flange

FWIW i made 176 mustang dyno whp(200 dynojet ) at 8-9 psi on my 1.6 with a small 16g. I make boost before 2K and make more than 100 lb/ft before 3K easy.

yeah understood for sure. i want to do the twin scroll thing if i can. if i cant find a suitable twin scroll turbo, then ill just do a 14b and sweet tubular mani

If you are low boost then a 14b or 16g will be more than enough for you to be happy. The main adavantage to the other turbo's on our smaller motors is the top end breathing. The evo series strives to have the same or similiar low end effeciency of a small 16G/14B with better high boost flow 17+ psi than the big 16g's.

another possibility - the IHI vf38 from the JDM Legacy... also twin-scroll, titanium turbine wheel, dual BB. OEM rated at 280ps, which is pretty much on the edge of the tranny danger zone. Still a somewhat oddball flangetho.

It used to be pretty cheap 'cos the WRX guys couldn't do much with it.

**** that, I would stick with something common. Put a standard mitsu flange on there, rock out with your **** out. I don't think you're going to pick up 700 rpm spool with the twin scroll.

dirtyboost

yeah, been looking on nasioc for a vf37 but its way too pricey. havent looked into a 38 but its a possibility.

if any suby guys are lurking around this thread, i bet a single turbo off a legacy b4 would be great. I bet that spool would be incredible .

now you're just being a cottonheaded-ninnymuggins

seeing as im planning on one hell of custom mani (have all necessary flanges), why not do the evo8 turbo.

tons of people run standard 16g turbos, i dont understand why i wouldnt see a signifiant reduction in lag over the standard unit...after all, thats why mitsu designed a twin scoll turbo in the first place.

fwiw, im like 70% sure ill be going with the evo 8 snail. ill be sure to bump this thread when the boosting begins this summer

maybe it's the stock manifold, but the evo 8 with the standard turbo isn't exactly a fast spooling beast.. i know a little bit about mitsu turbos.. we just got 80 grand worth of delivered today..

Dude Nester has turned quite a few Before he left KY i was always hitting him up for parts etc. The normal 16g or a 14b will do the job easily and effeciently. Ask juhanis how he likes his 14b vs the 16g he has pmed me before that the spool etc and low boost performance was quite nice for him. In a low boost app, you don't need a 600+ cfm turbo for that.

dirtyboost

can you make a few of those fall off the truck jk
if one falls off the truck, pm me. i have cash in hand.

i never said the 16g was the fastest spooling turbo (which i itself is reason enough for a twin scroll), i just stated that i figured a twin scroll 16g setup would noticeably better than an standard 16g setup.

what do you have against standard 16g setups, huh ?

(other than the later full boost and whatnot)

dirtyboost

nothing much, im partial to smaller turbo setups...i was just going to do a 14b setup. But, due to my hookup on the manifold and turbo, i figured why not.
