Re: 16g help
If you want power, stay away from MHI turbos. The turbine shaft is too small to support any real power for a long time. Reliability isnt even close to the Garret/BW realm.
I would def. avoid the 20g. or any variation of it.

Again, a larger Garrett will allow you to make the same numbers without running the **** out of it. Hell, I'd even go with a 60 trim T3 over a 16g lol. The bottom line is that Garrett>Mitsu. The sooner you realize that; the happier you and your car will be.

You can go with forced performance.

Pricey but fp is the ---- and a treat to deal with.

Re: 16g help
perhaps i can help since putting DSM turbos on D motors is what i do any way short and sweet on a SOHC no 16g will make 350 whp with out a very agressive timing map. i dont know how this pertains to the fact your a DOHC so bear with me. here is what i made on 3 different dsm tubos on the same SOHC D16z6
14b = 230 whp
big16g = 295 whp
bastard 20g from slow boy racing = 305 whp
while the bastard 20 g appears to have only made 10 more whp thats misleading that is the peak WHP gain, but at 5500 RPMs it made a whooping 50 more whp and ft-ibs of torque!!! and that is a huge gain down low.
all 3 of these tunes were safe and not aggressive and for 93 octane. I think you will make a little more since you are DOHC and also i was using a very restrictive 02 housing on the big16g, stock is only like 1 7/8s inch opening
and my exhaust on my car is also only 2.5 inch at its max. the rest of my motor is bone stock cept the pistons and rods and head studs.

Re: 16g help
niice, thanks man. yea im pretty much saying screw the 16g, too small. i know i guy (sikcrx89) whos selling his d series garrett mani bolted to the turbo, but its small.. i could swap compressor housings to make it big and run that.. but im not going to make more then 350whp with the stock head, it just wont flow. sould i go with the 16g and shoot for 300whp? or go with something bigger
ill get pics of what i did tonight when i get home. Thanks to all who are helping, does good.
the turbo and mani is "GREDDY D16 turbo manifold and GREDDY 15G turbo"
is that too small to swap compressor housings and make that 325-350whp? i know marcus is a good guy and wouldnt sell me crap, but im not sure about turbo sizes to say the least
pics of my intercooler setup, hoping to make a skidplate for it lol its 8 X 3.5 X notice i didnt cut out the grill or fog lights ha cause i got it to fit right.. its as high up as the bumper support will allow.
'
cut the plastics out so the bumper would stretch over the intercooler a little more...V
and some nice black paint in random areas and on the bottom ft or so of the engine bay...

Re: 16g help
hey bro let me ask why are you so concerned about a certain peak number? you know peak numbers are only good for bench racing. what fun is a peak number thats weak down low and then sky rockets at the end of the rpm range? first let me ask you this what are your goals with the car? will it be daily driver? drag raced on weekends? auto crossed? or just straight drag car? if your answer is the first 3 options go with the big 16g if its only for drag racing and no street use then go ahead and shoot for that big turbo set up. my CRX ran low 12s in street trim with only slicks bolted on using a big 16g and it was a blast on the street to drive, spooled very fast and gobs of torque. make sure you get a good 02 housing or port the stock one allot. dont underestimate 300 whp especially if your making a fat torque curve, it will smoke B series that are making 350 whp easily.

Re: 16g help
ha yea i was thinking the exact same thing.. i was talking to a guy i know who made 375whp with his dohc... but it only made 150whp at 5000 rpm, hah
im going to go with the big16g and shoot for 300-315whp. its going to be a street driven car, so 300 is great.
i have the 2 timer installed, so i wanna run like a 10 pound map, and then an 18 pound map, and be able to switch at the flick of a switch.. lol
im just a little power mad.. this is my first build and it all started with "im goign to boost my stock zc at 10 pounds on a 14b" and now im all the way to "wiescos, forged rods, acl bearings, .20 over, polished and balanced crank, and tons of other stuff..."
lemme know what you think, thanks
