Hi everyone, Just want opinions

d16z6 with mods in my sig, I have already bought a greddy turbo kit, I wanted to get around 225whp. Did I go with the wrong turbo? should I have gone with a t3 setup? as I speak, the shop is putting in a blockguard and srp 9:1 pistons with eagle rods. Should I resell the kit and buy a t3 and manifold? I picked the greddy for its very fast spool. Im also working on getting hondata 2b. any input would be helpful thanks.

yes..get a bigger turbo...

now wait..i knew a guy that put down 300whp with a greddy kit. although that was at really high boost, wastegate didnt hold very well, fully built motor and a standalone. But still impressive never the less.

12psi in a greddy kit with a hondata gets you around 210-220whp with a greddy kit depending on the motor setup.

ok, heres a twist for you guys,,, its auto.(but already bought the lvl 10 rebuilt kit)

also I heard the greddy turbo isnt really that effective at higher boost lvls.
also how much more boost can the car handle with a blkguard?

You want to give me details on the auto tranny build? I understood they (B and H-series anyway) were stout once the fluid pressures were tweaked and the clutches upgraded. I've always been curious about those.

The SOHC Greddy turbo is going to be pumping a lot of heat into your engine to get over 200 whp with auto tranny power loss. I would avoid going that high without a more efficient turbo. Upgrade to another Mitsu might be a good suggestion since you already have the manifold... see what the situation on T3 + mani versus upgrading Mitsu costs.

Hell, drive it around at sub-200 whp and tune it and enjoy it and upgrade on down the road... it'll be lots of fun regardless.

greddy is good for emissions, reliability and legalty but as for power its some strait ***. lol t3 is better for power, good spool, can be used for drag racing or autocross all depends on your housing.

I think the limiting factor for the greddy is the fugged up wastegate housing/downpipe...it's really pinched off. My personal opinion, that I don't believe I have shared on here, is that Honda guys (and alot of imports) tend to go with turbos that are WAAAAAY too large for their power goals. I bet the Greddy turbo doesn't fall out of it's efficiency range on your (our) engine until 15-18psi (just a guess) so, if you aren't running more than that, you are sacrificing alot of spool time for a few more ponies from the cooler charge air.
::EDIT:: As a counter-example, go look at the "small" turbos some DSM guys run and notice they have larger engines and are making GOBS of power...::/EDIT::
As far as I understand larger turbos do NOT make more power because they are larger. They do so because they heat the air less. SO, unless you have a really good intercooler and you are running out of the efficiency range, I think it is choady to get a bigger turbo. I am running a straight-up T3 and won't be going above 12psi, me thinks, so it is even to big in my book.

This is just my opinion, which differs from most (as far as I can tell) but, I believe mine is right because PV=nRT ...if someone wants me to explain this, I'll be glad to, but I'm heading off to dinner. Or, you can look it up in a chemistry or physics text under gas laws

now to what rember even with some people with what they call a Frank 3 turbo i have seen after i ran there car they stop and there manifolds are glowing red i beilieve that is not good just think of the EGT's on that run.

And the DSM's run less of a rpm then a Honda a GSR will rev over 8000 rpm stock when say a 1st or a 2nd gen to what i can recall only rev to say 7000 rpm so witch they need less CFM then compared to a Honda

The DSM's have small side mounts yes but ever drive a DSM with a stock turbo after 4500 rpm they fall right on there face but with a GSR with a Gen 3 kit pulls hard all the way to redline mine does anyway with all stock internals

Ever look at the ports on a DSM they are very small compared to a Honda ports what doesnt let the compressed air flow good in and out of the head compared to a Honda motor

Corect me if i am wrong with anything this is just what i think i have though of that long time ago

mien seems to be fine i got the greddy kit on my single... and it doesnt fall off and im pushing 10 psi sometimes it spikes to 12 i say stay with it and work with it...im pretty sure it will give you what you want...im pretty sure your set up can run with the wastegate line off
