S366 and 190?

Adamv7010 · Mar 9, 2013

Thinking of an s366 with 190/stock.

I would use CED t4 uppipes , probably wrapped

How would this setup pan out? Only thing I'm unsure of would be the stock nozzles...I'm afraid cylinder pressures would be a bit much

I rarely tow...when I do its less than 8k.

Street manners?

Elevation here is less than 500ft

With 190/100's should be very clean at wot, might have a bit of lag down low however.

I'd be afraid the stock nozzle wouldn't have enough fuel to offer up down low to spool it very well. I've often wondered how well a 190cc injector would work with a 66 though

Iv been down this road

Laggy= YES

When it lights it's worth blacking out the road

Just make sure your psi ratios are close as you can or install a waste gate.
Buying heads and doing it all over again is not cheap.

I went down this road as well. I think the overall performance depends one the setup. I ran innovative a tunes and their modded ficm and the spool up wasn't bad. From a dead stop the world got dark. But rolling into it it would clear up fairly well. The turbo setup will probably make a difference as well. I ran a Turbonetics on mine which was a 66 but it had a little bit more exhaust room. I was running a little over 1:1 backpressure.

This is one of my major concerns.

I wonder if the 364 would be better paired with 190/stock nozzles

I need to school myself and read up on backpressures...what's desired and what's not...I'm still kinda in the dark as to when a waste gate becomes necessary

I'd say the smaller the better.. 62 or 64

I ran a s366/68 bullseye bat wheel with a .70 AR t3 rcd adaptor (still have the adaptor for sale)
Injectors 190/100
Tunes custom idp

So my exhaust psi was always high do to the t3 housing

You want your ebp and mgp to be the same at peak
That's were a gate cone in to dump the ebp to keep it the same as the mgp

This crossed my mind...

I really can't decide if I want to spend the extra $ now for nozzles...

But I know I won't be satisfied with stock sizing very long...Id expect the 366& 190/stock to be a powerful setup...but as you stated be tough to get spooled. The divided up pipes would help some but how much

It depends n what u want= drivability wise
If you like street racing hittin that 60 psi of boost
Or running a consistent like 35 psi and light amount of lag.

01PSD · Mar 9, 2013

Honestly if it were me, I'd wait and go ahead and do nozzles while you have the injectors out. While it isn't that bad pulling them back out... it isn't that fun either LOL you have a lot more options turbo wise once you have larger nozzles

Dieselcraft · Mar 9, 2013

This is my now turbo it's great

This is my up pipes and manifolds

I went from 100 nozzles to 75 nozzles
I like them alot better they don't haze like 100 s do

Basically i want a potent streetable truck. I dont mind a little lag...but dont want to take a city block to spool...by then the race is lost...lol

This sounds like the better option...and for 6-700 more dollars...might as well
