I'm interested in the exhaust manifold. Only the exhaust manifold though. I would need to know if it could mate up to a Garrett T25 or T28 turbo with the turbo exhaust and intake openings facing the sides of the car. I would also need to know how it looks like. Pictures are worth a thousand words. The specifications would help me out as well. The injector flow rate is something I'm curious about. Why a T3/T4 turbo? That's huge, isn't it? What's the maximum boost pressure that you'll be able to run with one of those?

definately grey- all im waiting for is my tax return to get started- i wanted to use a larger turbo so as a- im not stressing a small turbo to its max and most importantly- i can run more boost easily when i get to build the lower end- also the availibility of having sramble boost- hehehe ZOOOOOOM!!!
A company called South Florida Performance makes many custom turbos and theirs should be ready anytime between now and the end of the month. they are also using the T3/T4 turbo. If you go strictly street legal in these cars you'll be all show and no "go"
The T3/4 hybrid is rated up to 200-400 horsepower (depending on compressor wheel). I don't think we need that much! If you're still thinking of using a T3/4 hybrid then check out this page: Installing the hybrid T3/T4 turbo.
A T25 is limited to around 250 horsepower, maybe a T25/28 hybrid would be better? The T28 can produce upwards of 350-375 horsepower, so again I think that's too much. I don't know all the details yet, but I think a T3/4 hybrid turbo is too big for our engines.
The returnless fuel system thing is where our cars do not have a fuel line going back into the gas tank from a pressure regulator up front. The fuel pump pumps out more than the engine needs and the fuel pressure regulator up front keeps that in check and returns excess amounts of fuel back to the gas tank. When upgrading to a turbo you can simply replace the fuel pump with one that flows more fuel and get a new fuel pressure regulator and crank up the max limit. Our cars do not have a return line, so the fuel pressure regulator is in the tank along with the fuel pump. That's what it's about, but I don't know what the exact problem is?
Im with Grey, the t3/4 hybrid is too big for a stock engine. Your are goning to have to build your bottom end to hold all that. Wait a minute, no one build stronger bottom ends for our cars!!! I think the T25 or 28 would be the best bet to go. I personally would only put a T3/4 on a DOHC powerplant, not these little single cams flower pots. And like what has beeen mentioned twice, how are you gonna get around the returnless fuel sys?????

isn't the fuel pump for 7g civics and 4g tegs in the fuel tank so we can't change them either?
I also agree with Grey and Turtle, T3/T4 are too big, you'll have a lot of lag with it, a smaller one should work better, faster spool up and more power through the entire rpm range...better for some twisties, not just drag
<< isn't the fuel pump for 7g civics and 4g tegs in the fuel tank so we can't change them either? >>
Yeah, it is in the fuel tank, but I think we can change it. Lift up your rear seat and you'll see an access port. I think you can get to it from there.
ok guys- definately very valid points- ill talk to josh- (the guy helping design) he has quite a bit of knoledge in the world of turbos- his current car is a 982 rwhp 300zx running dual t05's- the thought of the t4/t3 hybrid was the first off his lips- like i said before- i need a few more weeks to get everything stragined out- lets keep brainstorming and well see what we come up with K????????- oh btw what would be really nice is charts of diffrent turbo's outputs- i rember one site that had all the info on diffrent turbous- showing output and effecency- thanx guys- oh btw anything you guys come up with will help speed the process!!!!!!! okedoke??? good- oh and one more thing- after we all get this going WHO THE HELL WANTS A DAMN KIT!!!!!!! TURBO BABY!!!!!
well as for teh price we need to see how many people want one and we need to see how much this kit turns out to be- alsoas far as the fuel system is concerned- its seems like an easy fix- just a matter of getting a pump and getting some kind of electronic fuel management system- no biggie
