Need Help turboing

[jdmracers]

hey guys,
i have a honda crx with a b16a1 engine and i would like to turbo it but i looked and looked at a lot of different forums and i came across a forum that said that "VTEC+Turbo = a valvetrain that needs replacing every 10,000kays due to the higher strain of forced induction on all the really clever tiny pieces that make VTEC work..." also said this "The question comes down to what the car is for. Why did Mr Honda invent VTEC? So it reduced the need for forced induction and greater fuel economy etc... Everything was done for a very well thought out reason in the Honda engines, and forcing them with air is something they weren't designed to do. better off with a ram pod and some other goodies..."
So, i just wanted to know what u guys think and if i sould sell my b16a1 and get a ZC and turbo it?

boost the b16
and the u dont need to replace ur valve train every 10,000 km....b16's can take up to 19 PSI on stock internals....besides a block gaurd and heap gap. but f ur running 7 PSI then u are okay...
i have a crx fully turbo charged on 7 PSI with a stock motor and i run [email protected] MPH...can u imagin wat a b16 with bost can do....

hey, thanx
but are u sure because a vtec engine controls the air and gas the engine puts in so if i add a turbo will it just add more air and so will the vtec be ok. If yes what turbo brand should i got with what would be the best.

[GWInquisitor14]

Ya the turbo wont effect the vtec valve train anymore. The only different thing is the addition of another lobe on the camshaft and the oil pressure vtec piston thing. Vtec is just so u can have these small 4 cylinders and put out hp of a v-6, to make more appealing to the average consumer. I guess theres a lot of ways to look at it. Id say go for a turbonetics or Garrett turbo.

19psi on stock internals ??? no way bro..it can be done..but not for long boom boom

[Tranzlogic]

more air = more fuel..a turbo kit will come with the correct size injectors for teh turbo and boost you select..so you dont have to worry about all teh extra air due to the added fuel.. and im with GW go Garrett or turbonetics ...Or go with a full kit and will more than likely be Garrett ie: a greddy kit

i really wana go with the stage 3 turbo but what do u guys think

[GWInquisitor14]

Thats great, but lemme point out a few things that aren't so good. That manifold is the crappiest one ever, get a nice stainless steel one. Mild steel will rust and crack pretty soon, especially with intense driving. Check out www.full-race.com. The fuel management on that is just a bandaid fix. You need a good fuel managment like a AEM or hondata. I personally, do not like pre programmed stuff cuz u just dont know if theyre set for ur car. On the other hand, i dont know much about MoTec. If you get that upgrade, the fuel pressure regulator is useless. Then, the injectors. Are 990cc the ones for ur engine, or are u just taking them cuz their big? Cuz theres a lot of math that goes into determining the size of the injectors to use. Last, u might not need to do this, but maybe go w/ a better brand name on the parts, Id susgest finding the best parts somewhere else, and not getting the kit

[jdmracers]

i am just going with the 990cc injectors because its what comes with the kit.

ok, ur saying that i should build my own turbo kit, ok well i want something like that stage 3 turbo but like u said better. So can u give me a list of parts that i should get to make a kit just like that or better and what type of turbo to use.

You are going to have to do some work to your block if you want to run the hypo stage 3. 15psi is way to much for a stock block. There is also no way the stock stock block can handle 19psi as mentioned above. if you want that kind power, you are going to have to get forged pistions, and rods, probably re-sleeve it and close the deck, and get a good head gasket. The most you should run is 8psi on stock block. There are people who have run 10psi on the stock block sucessfully, but they had a hella good tune. But still can be done. as far as which kit, I would say go custom since you already have a good Idea of what you want. You will see the best power outcomes that way.

[jdmracers]

i am going to put pistions with a compression ratio of 8.0.something i think its 8.0.5 so what do u think of those pistions.

What rods, head gasket, and block should i use or what is the best to use. With the hypo stage 3 kit that i am going to build.

[GWInquisitor14]

Heres my list of parts for my planned turbo build

Custom Manifold
Garrett T3/T4 TURBO
Hondata
Custom Downpipe
Tial 35mm Wastegate
HKS Blowoff Valve
Custom Intercooler Piping
Oil Lines
Silicon Hoses
Intercooler
AEM Fuel Rail
660cc fuel Injectors
Apexi Boost Controller

[GWInquisitor14]

What that premade kit is going to do is add 2 injectors right before the throttle body. I am going to get 4 new ones and use hondata to tune all the fuel curves, then there is no need for those extra injectors.

[jdmracers]

thanx
but how much power do u think it well make with my b16a1 in my crx

and

how much power do u think it will make then i do Engine Sleeving, new pistions with the CR at 8.0.5 (so i can run high boost), rods, cams, springs retainers, values so in other word do the works and will this turbo kit be good for this

[GWInquisitor14]

Well you would put the sleeves in to be able to boost higher, it wont really give u any gains if u keep it at the same psi. Same w/ the low comp pistons. All the valvetrain upgrades will make it able to rev higher and the new cam will adjust ur powerband.
