I'm going to boost my H22 in my 92 civic. I dont know a great deal about turbo's but I'm having it tuned I just need to know the gear to buy to make it possible, I have the idea and concept underway. Looking for around 340-380whp and 270-310wtq. It's been dyno proven to be able to on stock internals. Just looking for some pointers on what to buy. What size intercooler would be best fit Size wise and inlet /outlet sizes?, What size charge piping would I want to go with from turbo to intercooler and intercooler to intake manifold? What type of WasteGate?, Bov?, And the size of the Down pipe. I have a rough idea, just like to see what u folks think.

Thanks

Kyle

Heres a setup I did on my ex-gf's civic, The JRC and CCA 6-8in intercoolers both work pretty good on 92+ civics, I'd go with 2.5in Charge piping, and you dont have to do a ball bearing turbo (like shown above) For 350whp on a stock internal'd motor, I'd definatly go with a SC61, downpipe can be 2.5 or 3.0 just make sure it has a flex section in it.

Do some reading through the turbo projects, do a couple of searchs and you will find what you are looking for,

Wow, Fast replies here, not too offen u see that, Glad to be here. Great site and useful information. I was just sorta in a bit of a hurry to find it out. Thanks for the pointers.

 

Do not skimp on tuning, Highly suggest using either Hondata, Uberdata or Crome(find a good tuner local, use what he uses)
You'll probably need 550cc injectors if not bigger. Good luck, I'm working on a H22 turbo build myself.

 

Using 750cc RC injectors, Walbro 255 fuel pump. I have a P28 with Uberdata program now, and that is what they will be tuning it with. I've spoken with the local tuner and they seem to think it is possible. They have tuned a Stock H22a motor up to 380 whp. I have the quote for it to be tuned, just a matter of getting the right gear to make it possible. I'm getting the specs on a t3/t4 hybred Garret turbo tomorrow, I just couldn't get in contact with him today. I have to find out what that turbo is capiable of doing tomorrow.

So using 2 1/2" mandrel bent charge pipe is fine on both sides of the intercooler, 3" down pipe and full exhaust straight threw is fine?.

Now my question is Can I go to big on an intercooler in dimention wise, too think, long, and tall? or is it just more cool air, more power?

For this amount of power, is there a curtain level of a BOV I will have to purchase, I've read upgrading to a bigger BOV. Or will any Greddy or reg. BOV do the trick?

AS for the Wastegate, Is there a type sold that is adjustable rather then changing out the springs each time I want to up the level of boost?

What Size turbo have you chosen ?

 

The only downside to a large intercooler is pressure drop, as long as you get one that fits in your car I don't think you will have a whole lot of problems.

BOV are for preferance, I don't think you even really need one, but for the sound I'm getting a HKS SSQV(I'm a ricer). but you can get a bypass valve for practicly nothing.

For controlling boost, you want a spring that is below the lowest amount you wannago , but you don't really want to run twice the amount of load on the spring, and a boost controller(manual or electronic) will controll the amount of boost above the predetermined amount of the spring.

I'm will be using a T3/T4 .63ar cold/.82ar hot




I must admit though, 380 is pushin it, can be done but be ready if it goes out, have some cash on the side for a engine rebuild, best of luck to you though, post up soem dyno #'s when you get it done.

 

So lets just throw an example up,

30" x 10" x 3" vs 30" x 6" x 3"

Any large down fall using either sized intercooler?

The People that will be Tuning it have inpressed me, otherwise I wouldn't be so convicenced in boosting my h22 hatch. I don't think I know anyone else around my location that can tune aswell. Right now untuned with 1.8 GSR fuel maps up 5% with the p28 with Uberdata running my H22 in the hatch puts down 180whp and 154wtq. However I do know a motor doesn't last for ever and the amount of power increase turboing it with their tune makes me wounderwhy build. Building a motor just don't seem like the thing I would want to do with the power that can be made. New H22 $1000, proper motor build top to bottom anywhere from $2000-8000 could be endless.

 

*previous post edited*

I don't think the pressure drop will be that big of a deal between those two.

 

What is your turbo able to handle up to ?

And sounds like any intercooler I find that is best fit for my vehicle is fine with 2 1/2" inlet/outlet ?

 

My turbo can handle a little over 500hpr

Ya 2.5" will work just fine.
