Alright I just have a few questions and I know they've been discussed before but I really don't have the answers I'm looking for.

Backstory:

1993 Civic EX
D16Z6 with 260k
ARP Headstuds
Cometic HG
Comp Cams 59300
CC Titanium retainers
CC Valve Springs
Y8 Intake manifold
Fidanza LW FW
Exedy Clutch
Rear Disk with 40/40 prop valve and 15/16th Master
Koni/GC's
Full ES Bushings
I/H/C/E

I've put together the following parts:

Spoolin Log Manifold with 3" 4bolt dp 38mm Tial Flange
Precision 525 Injectors
Hondata S300 w/boost control
3bar map sensor
Walbro 255lph fuel pump
Innovate LC-1 WB02
Intercooler
Piping
Misc. Plumbing
Scat Rods/Vitara Pistons Hastings Rings
Tial 38mm WG
Forge Diverter Valve (blow off)

SOOOOO... it's pick a turbo time...

I'm looking at the following 4 turbos from TunerToys

466159-5003 T-3-4 57X63
466159-5004 T-3-4 60X63
466159-5005 T-3-4 57X48
715583-5005 60-1 T-3 .48

Now I'm pretty heavily leaning towards the .48's and most likely the 57 trim. But I'd like some opinions from some people with experience.

Goals:

Daily driver with ~300hp low boost map and 400-425 high boost map.

The main reason I'm leaning towards the .48's as opposed to the .63's is I'm not going to be running it up to high RPM all that often and would like the have the power available at low-midrange RPM's for daily driving... a mash of the peddle i/o downshifting.

ALSO...

On the vitara's... I know that people are making great #'s with them... but how low do they really drop the compression and how badly does it affect the running of the car out of boost??

Am I better off getting stock replacement forged pistons from another company?

I am definately trying to keep the budget down on this project but I'd like to do it right and spend the money upfront for once.

Any advise/thoughts welcome.

 

Bump.

 

Now also looking at a Borg Warner T3/T04B 57 trim turbo with .55 a/r...

Really just wanna get an idea from some experienced users if/when any of these turbo's will choke up on a Mildly built D16Z6.

Any input really REALLY appreciatted.

Just looking for ~300-350 for daily driving with the option to up it to 400-450 if I want. (525's won't support that much HP will they?)

no, 550's wont support 450whp either, neither will your build, 300whp will be PUSHING it on your build!! You have a stock block dude.
for turbo selection.. i would use a t3/t4 50trim

I don't see how my build is lacking?

he has stock sleeves/crank... I've got replacement rods/pistons

Am I missing something?

**EDIT**

Log manifold going to be the limiting factor?

Here's the deal... everyone always says in all these threads GET HTE BIGGEST... and I frankly just dont' want that... but I also certainly don't want a 50 trim... that's like a stock turbo charged car turbo. I'd like to get something that will spool up decently quick and have top end capabilities w/o being rediculous.

I just don't want to end up buying another turbo later when I upgrade the manifold and injectors.

Although if that's the best decision then so be it...

**/EDIT**

 

i dont believe his car is a dd.... and also those numbers were put down on race gas. i dont see how a 400+whp stock block d series could be very reliable for a dd but then again thats just my opinion

Alright fair enough... but for DD I'm only talking 300-350...

Water/Meth injection is prob. in the near future too...

I'm going to install everything and tune it pretty modestly at low boost at first and go from there... I'm not looking to daily drive it at 400whp by any stretch. that'd be on the track or occaisionaly.

What is the current perceived max. HP for DD stock sleeve D? And is posting or block guarding an option to increase that? I could have the block posted for next to nothing...

Maybe I'll just go nuts and buy a second block and send that out for sleeving.

Any input welcome.

 

If you're shooting for over 400whp, get a larger set of injectors. Those 525cc's will max around 380-390whp.

With the turbo selection, the .48ar housing may not reach your power goal without the IAT's skyrocketing. I would go with the .63ar housing unless you'd rather sacrifice top end power for streetability.

 

The Bullseye Power 57 trim will make 300whp with no problem and with the .55 a/r turbine housing on it the spool will be very fast. 300 whp at about 12 psi.

Awesome, THANK FOR THE REPLY

That borg Warner I list above (T3/T04B 57 trim turbo with .55 a/r) seems like it would be a great balance between the two or do you really think it's neccisary to go with .63? When would that turbo spool approximately?

This is definately going to be a driver not a track car... I have another car so if it blows up I'm not stuck... but I obviously am not looking to blow it up.

Right now I enjoy driving the car just want more power... I'm thinking that even 300whp even is gunna make me cream my pants by comparison... but everyone ALWAYS says that I'll get tired of it eventually....

I'm just trying to build a setup that will function well as a daily driver but be capable at a track as well...

Upgraded injectors are def. gunna wait, same for the better manifold... I haven't even installed yet... so I'm not gunna go from (what like 120whp (AT MOST) to 400) figure I'll do it in stages...

Streetability is DEFINATELY my goal... I'd prefer to shift at like 7k i/o 8k if it means having more torque from 3-5k Peak HP isn't really what I'm concerned with. More looking for a car I can drive at 1/4-1/2 throttle at 3k and just stomp on it for power instead of having to downshift into 4-5k rpm range.

 

Well my suggestion for now since you're not planning to upgrade injectors is to get a T3/T04e 50 trim .63ar and run that around town. Once you're bored of it and ready for an upgrade, do everything at once. I did my car in stages like that and it worked out nicely. To me it just doesn't make sense to get a turbo for a goal that the rest of the setup can't maintain.

Congrats!

Alright all thanks for the input... I'm gunna look around but I think I'm gunna be picking up that BW, it seems to be the middle road on the exhaust AR and capable of my eventual goals but still safe to run under that.

Thanks for all the input guys.

Look for my build thread starting soon.
