6 port turbo kit
 
Is there any one who makes a 6 port turbo kit?

Before I get flamed I have searched everywhere.

Cartech. It's old like saggy balls, impossible to find. You're better off doing it DIY by results from searching here.

DNA motoring has a manifold. I can get you one for a discount too

beachFC 07-20-13 09:43 PM

t3/t4 btw.

How much Beach? I don't have money yet, but trying to do my research before buying.

I am not aware of any currently-produced kit. Most people piece together their own kit, which typically includes a turbo (the most common are a 60-1, TS04, T04E "60", or GT35R), wastegate, manifold, front-mount intercooler, downpipe, water and oil lines and fittings, downpipe (or an entire exhaust system), cone air filter and custom air box, standalone EMS, upgraded fuel pump and injectors, Aeromotive or SX fuel pressure regulator, boost gauge, Turbo II transmission, starter, flywheel, driveshaft, differential, and halfshafts. Optional mods are lower-compression rotors, engine rebuild, porting and doweling. Plan on spending about $10,000.

If you don't want to spend a lot of time and/or money, then the cheapest and easiest way to go turbo is to sell your car and buy a Turbo II car.

Sounds about right, aside from the $10,000 part. A few more items could have been added to the optional list :x including: T2 tranny(and all the other t2 shit), standalone ems, and front mount(port matched stock t2 lim/uim can be used along with intercooler)

That being said, Evil Aviator described the RIGHT way to do it hahaha. Do/get everything he said for a proper set-up. But if you plan on blowing up the motor/tranny in a month, expect to spend about $2-3k

Yes, if he wants to keep it below 200bhp then he could forego the TII drivetrain, and ghetto-rig the stock EMS and air box. However, the OP did not state his budget, performance goals, tools, or skill set, so I listed the more common path to the conversion.

No one makes them because:

1. There is a factory turbo RX-7, the TII.
2. Most owners are way too cheap to afford the cost of a commercially produced turbo kit.

I have again and again looked at bringing one to the market but always, I come to the conclusion that there are precious few people who would be willing to pay the $4500 for a 300HP bolt on NA-turbo kit. It's important to remember that such a kit touches every system of the car and if comercially produced and sold, must be reliable and as close to bolt-on as possible.

$4500 isn't even really that expensive. Look up some of the prices for the bolt on supercharger kits for the popular new muscle cars and prepare for some sticker shock.

That all said, if you use the TII lower intake manifold, then you can use any turbo kit or parts designed for the TII.

Well, looks like I'm buying a TII because that seems way more expensive than I had imagined. Thanks for the info any ways. So now on to the TII, HP goals are around 250-300rwhp. Is that feasible without boat loads if cash?

wthdidusay82 07-21-13 11:18 AM

close to 250whp can be done on the stock Turbo and supporting mods , 300whp who you'll need to upgrade your Turbo to at least a bnr stage 1 hybrid

Fast. Reliable. Cheap.

Pick two...

I just made 340 whp with my 6 port turbo on 12 psi with a bnr stage 2

Yes, with a Turbo II you can get an Rtek chip, BNR turbo upgrade, Walbro 255 fuel pump, and appropriate fuel injectors. Optional components are a front-mount intercooler, upgraded radiator, and aftermarket exhaust. No tuning is required for these bolt-on mods, and they do not require a great deal of mechanical skill or expensive tools to install them.

all it really takes is a modified turbo lower intake and a drilled front cover for the turbo oil drain.

it's far too difficult to bother with the 6 port intake system, the actual simplest way is to just weld and port match the turbo lower to fit the 6 port block and then just transfer all the turbo parts to the n/a engine. most of the parts can be found for about $500 off a turbo engine shell, a welding shop would probably charge about $100-200 to modify the lower manifold.

Thanks for the info, seems all relatively simple. I don't lack tools or knowledge as a buddy of mine owns a shop and has extensive knowledge with rotaries and I've been learning loads from him. But I am getting mega squirt for my car, so I don't think I would go for the Rtek.

I swear I'm not trying to thread-jack, but, speaking of the Cartech kit, would that be one of these?
Yet another project convertible followed me home on Friday and it had this bolted on to it:

I've been trying to identify what I have. From the bit of info I can find, all signs point to it.
Air pump is still in place, turbo fits under the manifold, radiator for the air to water is up at the front and it's got the metal hockey puck looking fuel pressure regulator.

I know a thing or two about finance. Please to not waste money on unnecessary sports car accessories when you are a broke college student. Rather, wait until you are established in a good job, have paid off your college loans, and are funding your retirement through an IRA and/or 401(k).

Cartech made several different kits. I do not recognize yours as one of them, but it does seem to have some similar properties.

It certainly does. I also noticed that the Fuel Pressure Regulator actually says Cartech on it. Although, it's possible somebody sourced one of those to go with some other kit.

Yeah you are probably right, but I have my school paid for by the gov't and I basically work for my car, insurance and gas. By "broke" I mean I don't make a lot.

Looks like the cartech water-to-air intercooler. Here's a couple pics of the booklet I have. It's made to fit the '86, so it works around all the 6-port stuff and used a T4 turbo.

Wow. That's awesome. Looks a lot like it. Would there be any way I could beg/borrow/steal an actual scan of that booklet?

Anyway, I'll stop thread jacking and back to the original question.

Ah, so that is what the 2Gen version of the Hy-Therm looks like. The 1Gen version had a smooth top and the hoses were on the passenger side.

That is a very short-sided viewpoint. Unfortunately, this is typical of Americans because our elementary school education system sucks. Hopefully you will take a personal finance class in college so that you can learn about compounding interest, credit ratings, and how to plan for emergencies and retirement. I'm not sure why you are going to college, but hopefully one of your goals is to not live paycheck to paycheck for the rest of your life.

If you spend $1,000 on your car, it is gone. If you rather put that $1,000 into an investment that averages 7% APR, it would grow into about $15,000 40 years from now. In a similar example, if you spend $500/month on new car payments and keep replacing your car with a new one, in 40 years you will have a pretty good used car. Were you to put that same amount of money into a 7% APR investment, you would have over $1.2 million dollars after 40 years, and it would generate an average of nearly $87,000 per year for the rest of your life.

In the near term, you should watch your spending because it is typical of new college grads to spend an unexpectedly large amount of money obtaining a job in their new career. Most college students should have a stash of $8,000 to $12,000 to cover the costs of moving, new clothes/uniforms, office equipment/tools, housing and utility deposits, and maybe even additional training costs, depending on the situation. Additionally, those who have had their parents pay for their living expenses will have a rude awakening to how much the "little things" cost. These costs kick in immediately upon graduation if you are not still living at home, regardless of whether you have found a job yet.
