I orderded the cooling mist kit, they ask, "Tell us your horsepower or receive the standard 380 CC injector." What injector are you running?

My injector would be close to their 90cc injector.

I think I'm getting close to starting my turbo build. I have been gathering parts for close to a month and should be pretty close to jumping off. Here is my list so far, if I have missed something please let me know.

1) airesearch T3 from '81 benz
2) manuel boost controller
3) blow off valve
4) methanol / water injection
5) boost gauge
6) oil supply and return lines
7) psc1-002

Items that I plan to get or I'm working on:
1) AFR
2) injectors
3) piping
4) heat wrap
5) turbo mount

Did you get the PM I sent you regarding the water/meth injector?
You can add - adjustable fuel pressure regulator (talk to Sharpxmen)
Air filter,colder plugs

he did, got a couple in the works, should have it shipped out to him this week

Air filter,colder plugs

plugs 2 levels colder

I did get your message and had them send me the 90cc injector. So other than a few minor things I should be about ready to go. What size pipe are you running on the iduction side?

Thank you both for all the knowledge you have shared with me thus far!

What size pipe are you running on the iduction side?

i am using 3'' to the filter and 2.5'' after that (although i want to upgrade to a larger ID from the filter to the t/b since my t/b is 64mm and the 2.5'' pipe is a hair below 60)

In your case i would at a minimum match whatever your turbo inlet is (at the tip, not at he turbine). You should be good with 2.5'' and at the most 3'', anything over  would result in negligible gains for the CFM you would pull with 6psi of boost (or even for the size of the motor. 

[st.chevrolet]

On the filter side I matched the pipe to the turbo inlet size and then had the pipe expanded to match a K&N I already had. For the turbo outlet pipe I matched the pipe to the TB size ( I have the 4.0 TB) and used a silicone reducer right at the turbo to step it down to the turbo outlet size. You can see the pics in my thread.

This may seem like a stupid question but, how do I go about getting a colder spark plug?

This may seem like a stupid question but, how do I go about getting a colder spark plug?

I bought NGK ZFR7F which have the same specs as the stock ones other than being 2 numbers colder, stock ones are 5 these are 7, they go backwards - the lower the number the hotter the plug - the colder the plug the faster it removes heat from the chamber.

$2.50 each on ebay + about $4 for shipping

Ok I am new to this site and have spent the last 2 days searching about turbo's and I want to know what you guys think about this turbo kit http://cgi.ebay.com/ebaymotors/Jeep-TJ-T3T4-Turbo-Charger-Kit-_W0QQcmdZViewItemQQhashZitem3efb5a0355QQitemZ270504952661QQptZMotorsQ5fCarQ5fTruckQ5fPartsQ5fAccessories
Sorry if this has been covered before but I couldn't find it.  It seems like a pretty complete kit to me.  Thanks for the help

far from complete and probably with parts that you don't need or never use - not sure why they call it TJ kit as there is nothing in there for TJ - just a bunch of parts (made in China most likely) that a street tuner would use put together in one package.

I've helped build several turbo cars. If you want success, lack of issues, and a decent running engine, start with a name brand stand alone engine management kit, then the turbo....

i think MSD has some standalone MPFI systems (ECU and harness only) that work for 4/6/8 cylinders and they range from $1,200 to about $1,600 - not sure how well they work and if you can use the stock sensors (like crank, cam, tps, IAT, CTS - map will work but for forced induction you'll need one that matches the boost most likely 2bar in this case).

and there's always Megasquirt and the piggybacks for a cheaper alternative.

Ok. Jeep is at the dyno shop and is getting tuned tomorrow. I'm so excited. I'll get you guys some numbers on what its running. For those of you who missed it, i'm having the ftc1 installed to be able to tune the motor. I'll take some pics and stuff for you guys too.
