Large framed turbo options for 650whp-750whp B16A2 power plant?
Going into a 1990 CRX HF. b16a2 SRP Pistons, Eagle H Beams, ARP head studs, Walbro 255 FP, Precision 1000cc injectors, stock intake, stock TB, 2.5" exhaust, Y1 LSD trans. I previously had a stock block b20 making 220whp on 8psi with this kit. It's a Go Auto Works street b series kit with a Turbonetics Super 60 .48AR turbo, cast iron manifold FMIC, Tial WG and BOV. I'm told this turbo is only good up to 320ish HP, what would my best option be? I don't have a set HP goal in mind I don't want to push it I just want safe HP I was thinking I'd like around 400. I'd like a "plug and play" turbo, I have the t3 flange and downpipe already as well as the oil lines so I'd like something that will bolt up exactly the same. Or should I just use what I have?
re: Large framed turbo options for 650whp-750whp B16A2 power plant?
I'd leave what you have, up the boost to 15-16PSI and just see where it gets you (nowhere close to 320, but you'd have a lot of other hurdles to cross before going anywhere beyond 350).

Can you further explain? What are my limiting factors? And what hp do you think I'd be making at 15psi?
re: Large framed turbo options for 650whp-750whp B16A2 power plant?
I’m in the same position as you. I’m really trying to figure out what would be the right turbo for my new build. Something like a gt35 seems to be a popular pick but it seems to have its limits if your really wanting to go big (600+). I’m going to try to go precision turbo but they are so damn expensive, but you get what you pay for in the long run, I just don’t know what size. I’m hoping AZ will help guide me on this one. If your staying under 400hp I think a (good quality ) t3/t4 could do that but it would push its limits, that’s what I’m currently running and I was told by the place that build mine that 400hp would be the limit before being complete non effective..... side note, are you till on stock sleeves? If so I would think 4-450 would be the most you would ever try for anyway

pick your goal, find an appropriate turbo and build your motor, "t3/t4" is very general that could be anywhere between 200 - 800 hp and literally hundreds of turbos
It all starts with a goal we cant help much with that you need to tell us. plenty of examples and build threads for 400 HP, which would not require anywhere near a 356 More like a Gt 3076
honestly with precision you definitely dont get what you pay for at all IMO stick with garret turbonetics or maybe even holset

the turbo I have now was built 100% as a turbonetics without they’re logo, I had a custom turbo builder build this turbo years back. I’m very aware it’s not going to handle my new needs. My new setup will have a CSS block, wiseco pistons Skunk2 h beam rods, ferrea valves / springs / retainers , unsure about which cam at this point, arp head studs , je pro seal head gasket. Then whatever fuel delivery required to match the hp goal. I’m building it to handle 850 but will tune it to 650-750 range which will make a fun weekend track car. There isn’t enough support for imports in the area I live in to takes take any further.

If you are looking for a pretty good priced turbo that could make some power, see below. I had this on my car and utilized a ram horn with the turbo below which was the Garrett t3/t61 stage5 .82AR. It claims 600 but I made 715whp with that turbo and it got me in the 9's. I ran that thing for thousands of miles and never once had an issue with it at all.
It utilizes the GT35R compressor wheel with your choice of turbine wheel in a journal bearing CHRA. The good thing about this turbo is the cost, I mean it was a little over $800 bucks to get a turbo capable of 9's is good to me anyway.

I am guessing OP isn't in the market for 650-750 whp anymore LOL. Below are a couple turbos to choose from that are around the 400whp plus area and brand new are a bit over $600 dollars. However if you only have a $300 dollar budget maybe go with an ebay turbo.

Re: Large framed turbo options for 650whp-750whp B16A2 power plant?
Ok awesome! The thread got kind of derailed so I want to start over with my goals. I'm trying to make around 400whp on my car. Details:
1990 CRX HF
b16a2
Stock Sleeves
SRP Pistons
Eagle H Beams
ARP Rod Bolts
Precision 1000cc Injectors
Walbro 255
Y1 LSD Trans
Competition Stage 5 Clutch
Stock Intake/TB (willing to buy new if it would make a difference)
Cast Iron t3 manifold
Go Auto Works street kit (Tial BOV and WG 2.5" piping FMIC)
I currently have a Turbonetics Super 60 but I need something bigger. My budget is around $500 so I'm guessing I'll have to buy used. Are my goals reasonable? Sounds like maybe a used name brand 57 trim would be the way to go? Also on that precision why would it make my car slow? It would just take a long time to spool because the turbo is so large?

I would say the 57trim would be a solid turbo, it was my first turbo I ever ran back in the day and made 480whp with it and daily drove everyday with that thing. If you can find a used one you should be able to find one for 500 or less or just save the extra 150 bucks and buy a brand new one with no problems.

is the engine already assembled? If not the only thing I would recommend would be something like the JE pro seal head gasket. That’s what I keep getting told works the best with a non sleeved block. Stock sleeves can move at higher HP which is why head gaskets go. Apparently the JE Pro seal gasket has seal ring for each cylinder which allows some extra forgiveness

‘I plan on making it out to a larger event on the west coast next year, I’d love to see yourcar run if we could arrange a event your going to. As for turbos, I started off using the GReddy kit for the Civic , I think it was only like a t25? Or something like that? It got me down to a 13.05 on a stock SOHC though.
Re: Large framed turbo options for 650whp-750whp B16A2 power plant?
Personally wouldn't go used u never know for sure what condition it will be in just wasted money imo. You can get brand new journal bearing for 500 or 600 from go auto
as far as spool yes it makes your car slower on the street as your out of boost more often then not with a larger turbo. At the track your always at upper rpm so bigger is better in that case for the most part
Re: Large framed turbo options for 650whp-750whp B16A2 power plant?
Ok I know the Precision ptb300-6162 .60AR is good would it be stupid to buy it? I was thinking maybe later on I'd want to try for 450ish but if it's gonna spool too slow I'll spend the extra $ on the new garrett
Re: Large framed turbo options for 650whp-750whp B16A2 power plant?
Everyone here hates precision so you won't get many friendly responses they have a tendency to fail prematurely. Like I said I recommend turbonetics or Garrett both are good and availible thru gaw
6162 is rather large especially since it's going on a b16 smaller motors have a tougher time spoiling the turbo. I'd be looking at a 57 trim or a turbonetics 5857. Turbonetics seem to work quite well they have a newer blade technology then the garrett
here check this out, this is from a member on here with a b16, beleive there was a cam change between the garrett and two turbonetics turbos so part of the gains were in the cam not the turbo

How do these look? Is the only difference the 90 for the IC piping? These are a bit cheaper and within my budget, I could stretch it that far and grab one of these. Unless the 57 trim Garrett from go auto works is 100% worth the extra cash
Re: Large framed turbo options for 650whp-750whp B16A2 power plant?
do you already have a 5 bolt dowbpipe or is it 4 bolt? The one with the 90* can be compensated with IC piping only if you have the space, with our engine bays usually not depending on placement
Those are a bit smaller 50mm inducer wont make the power your looking for
those might be clones at that price, id stick to somewhere reliable real st perfomance,if shopping on ebay. Greg might be able to spot the real from the fake Im not sure I can.
its a bit hard to beat Go autoworks prices However if you shop arround enough you can find them a bit cheaper just make sure your shopping reputable vendors
