Em1 b16a2 turbo options???
I just bought a em1 with a b16a2 still in it. Skunk2 stage 1 cam ls 5th gear, are the only mods the car has right now. I want to go turbo just like my other cars but this time I am on a budget. Here's what I want.
Budget:$3000
Looking for 350hp
Will be a almost daily driver on freeway to work (3 days or so)
I want a nice responsive car to rip and run in.
1.Trying to decide on if I should do
-A. quality turbo on the stock block,
-B. build the block and cheap turbo,
I do have a machine shop that will build the block for $1600. Weisco pistons & scat rods. That is one option.
2. What size turbo
-A. Gt30
-B. Gt35
-C. Gt25
-D. T3/4e
-E..50 trim
-F..57 trim
-G..63 trim
No to familiar with turbos, but I want a responsive turbocharged will do the 350 hp mark and not be leggy.
Thanks for all the help.

You can safely push the stock block to 300 with a GT2860R/RS, and get good response out of it. If you want 350 safely, have your machine shop do the building, save your pennies, and toss a disco potato on there. After the turbo, fuel system, and other related parts (plus the tune that you'll definitely need), and barring any freebies or great deals, $1400 won't go far enough to get it done.

Do yourself a favor and just get a Garrett t3/t4 57 trim you will have a blast with the STOCK b16a and this turbo....At least I did!! Plenty of room to make more power in the future.

Re: Em1 b16a2 turbo options???
what kind of fuel do you plan to use for 350whp?
Although the GTX2860R can be used, at just over 40lbs/min , will require at least 18-20psi at over 8000rpms to reach that level with the 54mm turbine wheel at 22lbs/min Exhaust turbine gas flow. At that point, he would need higher knock resistant fuel. which is why I asked the question of what he is going to use.
GTX2860R
Compressor Map
Turbine Map
The same goes for GTX2863R--GTX2867R.
The new GTX2871R, however, CAN do what he needs, with a little less boost pressure than the GTX2860R, as even though the turbine gas flow capability is the same as the rest of the GT28R & GTX28R series, it can flow over 55lbs/min. It'll struggle to maintain it without some drop in the higher rpm levels. but not as much. Its a beautiful mechanism for Roadracing on the 1.8 Litre and 2.0 litre VTEC engines.
GTX2871R
Compressor Map
Turbine Map
The GTX2871R that was released uses the same compressor wheel profile as the GTX3071R. The difference of course is in the name. The GTX30R series uses the 60mm N32 turbine wheel profile with better exhaust turbine gas flow at the same boost pressure.
91-93octane - 45lbs/min - 55lbs/min
This includes:
GTX2871R- Fastest responder
GTX2867R - Might need over 19psi or so
GT3251B
GT3000R
Hunter
GTX3067R
GT3071R
GTX3071R
EFR7163 -based upon staying with efficiency level no lower than 72%
Turbonetics - 54/F157 series
Higher knock resistant fuel ( C16/E85/Methanol) -
GTX2860R
GTX2863R - Similar to an 18G
EFR6758 - based upon staying with efficiency level no lower than 72%
Turbonetics - 54/F154 series.

Re: Em1 b16a2 turbo options???
I wished I bought a B20 block (I mean I still can)
OP I've been DD-ing a boosted B16a2 EM1 for about 4 years now\
$3k MIGHT be a stretch. How much are the GT28/30 going for 1-1400? That's half
Manifold, IC, piping, etc, is probably another $1000
ECU/tune/hondata and injectors are another $1000

Re: Em1 b16a2 turbo options???
I guess I'm really trying to keep the stock motor stock everything look going. Other than the turbo everything on the car is stock. Weird but that's what I'm going for.

Now hats a lot to take in. I'm going to be on 91 gas. After reading what you wrote the GTX2871R is what you recommend. Whay would I loose if I just went one step up to the gt30. Then would I get better efficiency and need a little less boost pressure to reach my goal??

Re: Em1 b16a2 turbo options???
I think I can work with slightly lol. So can if I go gt30 is that only made by Garrett and are they journal or ballbearing. And should really spend the extra money to go ballbearing. I will also be running a Ac compatible log manifold not the cast iron one.

2.5" cold side piping/3" hot side
PTE 5431b (do NOT get this turbo, I was stupid and impatient, to this day I cant find what the **** the CFM rating for this thing is lol, somehow it has not blown an oil seal)
RC 550s,Greddy Bov, Tial 38mm WG
P28/EC Tune
Pretty simple setup on a 99.9% stock b16a2 minus ITR cams, made about 280 at 10lbs
Would love to hear 1/4 times as well but the car's a little bitch and I've been having electrical issues so yea...lol

How do we know? You go through enough turbochargers you get an idea of what the wheel combinations can ultimately do.

I didn't quite say that... It was more to the effect of... IF you're on 91-93octane only,and attempting 350whp+ , you have to go up to the 60mm wheel of the GT30R series (That's why there's a list, because they ALL use that exhaust wheel).
Also... If you're planning on higher-knock resistant fuel over the 91octane fuel, and you want maximum responsiveness for 350whp-400whp only then can you use the GTX2871R as your option for the B16.... That uses a smaller exhaust wheel.
So, yes, in your case, you need to "step up" to one of the GT30R series question is, which one...

Re: Em1 b16a2 turbo options???
To a degree, yes. But he has to get the right combination, to get the least laggy effect. Its been done... done a lot. People tend to forget the efficiency factor of the VTEC B-series heads compared to others, even with a slightly larger exhaust wheel, a lot of lag doesn't come into effect for a while. If the compressor side is too large on the other hand, then yes, it can show MUCH less responsiveness.
