Turbo Specs

Oil cooled and water cooled

Compressor Specs :
1.70" Compressor Inlet
1.685" or 42.81mm inducer
2.362" or 60.00mm Major
Compressor .80 A.R.
M24 T2 Compressor Housing

Turbine Specs :
1.850" Exducer
Turbine .86 A.R.
2.090" or 53.10mm Major
1.820" or 46.25mm Minor

Aside from that, I been getting the peices I need to actually do the install and the fmu/megasquirt is up on my list and is pretty much the last thing I need to actually install the turbo.

Not only that but I have been doing major work elswhere on the car, new shocks, new paint job, new brakes and the autokonexion widebody kit which I also molded and left it as primer over winter to test for cracks so I can paint this summer. I got some mroe bodywork to do as well as finish with the tranny + turbo.
Thats just some of the larger things I have done.

At some point I plan on throwing in a brand new motor, and that would also be the point where I would do a more exspensive turbo setup.

Please go to the Meet and Greet section and make an intro post and post about your car and put up where you are located.

Yet again, DO NOT INSTALL A TURBO until you have installed MS and a wideband 02 sensor and spent some time learning how to use it.

Next you have not mentioned what manifold or downpipe you are planning on using. Also what you are actually doing with the transmission?

Well the clutch thats in my car its pretty obvious the throwout bearing is going bad so I just decided that because I have plans to turbo, that I would also put in a new clutch/bearing and the lighter flywheel. The tranny is out and my car is jacked, I just need to go out there and actually take off the flywheel. Maybe this weekend coming up.

Ill go do the meet and greet post here in a few, just got done watching lost and now im watching V.

I am assuming that you bought the FM1 clutch correct?

Yep that would be it.

If you gotta use a rising rate regulator, mine is the best one. Goes w/o saying, of course. It doesn't hold a match stick to a meagersquirt, but a band aid don't add fuel....

If you buy a used begi it can be updated easily.

I'd urge not using some fixed rate dude, and not 10 to 1 either.

Autokonexion widebody 1200... Sell it, and get stuff to keep it on the road. Such as a megasquirt and a wideband, and hell, some injectors too.

^This.

Wideband first or you will likely blow your engine. That seems to be a point of consensus among all of us. Or you can ignore us because we are all wrong and you know better.

I put the "go" before the "show" in my car so I don't understand the logic in putting a body kit on a slow car. I believe that adding to the substance of the vehicle should be a higher priority than shiny bits stapled on the outside. If you don't get the fuel/spark management right before you add the turbo you will have a shiny car to sit in and listen to the radio on sunny afternoons that won't run. How many excited noobs blow up their engines after trying to force a bad situation and do things half-assed before they are ready? Most of them. We are only trying to help prevent strife in your life with these suggestions. You may still choose to invite strife into your life if you desire, but remember our efforts on your behalf. Look around here at the build threads. We are mostly poor and are trying to build on a budget, too. Many of us have made these mistakes and have stories and advice to give. Study the build threads and learn form the mistakes of others that you may avoid them.

BTW, your turbo specs out to be a gt2560 equivalent. You should refer to it as a Chinese 2560 whenever discussing it on this forum so that others won't have to figure out what size you are talking about. Good luck.

Sometimes you just have to be patient with things, save your money and do it right the first time and have a reliable DD. I am assuming your car runs good now. Take it to some track events and learn to drive the car too it's max, now that way when you add all your goodies you will be able to handle to power. All my friend that are broke, are some of the best drivers because they take there under powered car and drive the shit out of them and keep up with people that dump tons of money in there car. One of my friends bought a 91 eunos (miata) for a $100 and saved it from seeing the crusher man. He drove the living shit out of that car. I seen him completely leave a R32 GTR on night in the mountains til the point you couldn't see the guys headlight and the GTR had suspension and power mods. Point in my story is if you don't have all the money in the world you still can enjoy these cars even in stock form.

I would love to have seen the look on the GTR guy's face!
