Hey guys! After 15+ years of wanting to turbo my '00 Civic Si, I'm finally acting on it. Im an older Honda Tech member and a lot has changed since I frequented the forums 10+ years ago. My car hit 90k miles and I need to do the timing belt, and so I figured lets put some piston and rods in while Im at it. So for the most part, it will be a stock head, eagle rods, arias 9:1 pistons, arp head studs, ACL main and rod bearings. I will be running Hondata s300, walboro 255lph pump, AEM fuel rail, still not sure on what size injectors....I really need help finding the right turbo. Last time I check, the t3/t04e was all the rage....but it looks obsolete now, or at least turbonetics is. My goals are realistically 350 to 400hp+ if thats attainable on stock cylinders. Otherwise whatever I can safely push with the hardware I have. Ive been doing a lot of research, but it looks like no one does a "basic" build anymore, especially with a B16a2.
Thanks!

 

That turbo will get you there, as for injectors they all work. Obviously some better then others, but would go with at least 800cc injectors.

Comp turbo has some really nice turbos, good prices also.

 

I wouldn't push it too much with stock internals.

You'll make 300whp reliably on 93. Anymore and you'll need forged pistons and rods.
The t3/t04e will get you there like mentioned above, but there are better and more expensive alternatives out there.

If I had an EM1 I wouldn't do more than lower it and some nice wheels.

 

like i said, i WILL have forged pistons and rods.

 

They would hold up to that power level on all stock internals, its been done before, but not recommended. It's all in the tune.

 

Thank you for all the replies guys are there any other suggestions on what turbo I should get or should I just stick with the Old Reliable T3/to4e?

 

This turbo is an excellent option. I'll be running the bb variant myself.

Hunter Turbocharger

What fuel is it being tuned on? This will dictate what size injectors you will need. Also if you plan on running e85 stick with ~10-1 compression, it will help the midrange on that little 1.6

 

This is what i came to suggest

Also, if you haven't bought pistons or assembled the bottom end, do yourself a favor and go 10-11:1, not 9:1

Injector sizing depends on fuel. If gasoline, then 720-880cc will be fine. If E85, then 1000s

 

hunter wont do 400 on pump gas

 

I will be running 93 octane.

 

Holset if you want cheap

 

at this point you may want to get a bit more specific in your goals. not knocking shodans turbos but if you want 400+ you will need to step up to a silver surfer or a similar size from another company and also accept slower response time. I was in the same boat I wanted 400+ otherwise I would have gone Hunter, quite a few builds just this week are using the hunter hopefully those users will share the results sometime soon.

from what I have seen 350-380 HP is kinda of a breaking point for the smaller turbos, quite a few out there that do 350-380 and then theres other units that will give you 400-450 or so. Ive been wondering about the turbonetics 5454 but havent seen any figures on a b series as they dont seem to be very popular. (turbonetics in general)

400+ silver surfer/Gt3076R comes to mind

You should probally have a look at lsjokers thread as he also uses a b16 he has quite a bit of data on different turbos and his journey to 400+

 

Im running the journal bearing Hunter from STC and i made 400hp on 93 (b18c) on a dynapac at 11-12psi. Currently running 375 at 9-10psi.

 

good info, of course theres alot of variation between different dynos. I would think you have more headroom since your only at 12 PSI

 

Wow, great information guys. I have to look at the silver surfer!!! I think that I have changed my goals and want 400+hp.

 

Run E85 and you can use the hunter to hit 400hp while maintaining response. Just throwing that out there.

 

Build specs?

When do you really get into the meat of the powerband?

 

stock b18c-r
peakboost manifold
3 inch exhaust
STC Hunter

 

Stock OEM headstuds too?

I took a quick look through your build thread, very nice build btw

 

Nope, i had some head lifting/coolant pressurization issues so i recently swapped them out for ARP studs and a new oem honda head gasket. All seems well now.

Thank you.

 

makes me glad I went ahead with a new hg and ARP'S. I was second guessing myself the whole time wondering if it was wasted effort.
Graph looks great btw.

 

I plan to do the same arp headstuds and new OEM head gasket as I plan to push my stock GSR pretty good too. Thanks for the info.

 

Good idea. What's another $200 at this point anyways? lol

 

Lol no kidding man. It's a slippery slope, I think we'll if I'm already taking the head off maybe I should just go ahead and do Pistons and rods, oh the heads off so I need valve springs and retainer, all this stuff is already going to the machine shop maybe I should just send it off to get sleeved... Haha it's never ending. Just gotta know how far you wanna or need to take it for your goals I guess.

 

Glad to hear I'm not the only one who has to have internal debates with themselves on a regular basis when looking at their engine bay haha. Throw in that new gasket and studs and I bet you'll do just fine for your goals man.
