Welcome, Heres my advice don't crash it!!!!! :biglaugh:

Do you got pics????

 

[Furyian]

lol I seriously hope it never blows up or crashes. I will post the pictures when I get home. There is A LOT of work done to this car. I spent 1200 in just gauges alone. It's also a 5spd and a targa top. I hope all of my engine mods makes the car last A LONG time.

if you want it to last, i think most everyone wil say drop the fuel cut defender.

what boost you running? and why NA cams have you tried both?

i assume you mean OEM afm, stock ECU and what not too?

 

[Scruggs86.5T]

are you sure this is an 86.5, they didnt have the targa option till 87? it would be a lot of work to make it a targa, there are a lot of structural pieces that would need to be added.

I'm pretty sure they did lol.

I look to run 12psi ... waiting to get insurance on it so I can really get it on the road. But I meant stock AFM and ECU but I am running a piggyback via the HKS FCon w/ graphics controller ... any particular reason to advise against the fuel cut defender?

I decided on the NA cams because I heard some people say it gives you a bit more torque and helps the turbo spool a little quicker

 

[Scruggs86.5T]

dont know where i heard or read that but i just found something saying they did. oops, sorry.

Negative, sir. On a GTE or even N/A->T car it's a waste:

If you're turbo, stick with the GTE cams. (and really, the it's the intake cam that makes the difference)

 

[dumbo]

yah thats why i was asking you about your cams, i'm a na-t and shortly switching to gte cams

theres a few threads on them, basically they bypass a major 'safety' that the ecu has. search it and that'll explain better

People reomend not runing hks FCD because MOST people do it to get ride of fiul cut without doing the nesscary fuel mods to go around or above 13 psi. Hks also designed it to go with there piggy back package. I assume your fcon has a 440 chip in it? Maybe look into a 550 chip and ditch the fcd. You said you spent a lot on gauges ao I assume you purchessed an A/F gauge. Make sure you pay attention to it. It will tell you if that FCD is hurting you engine.

I have eagle rods, weisco pistons, ported head, oversized valves, a 60 trim ct26. And I haven't ventured past fuel cut because besides my walbro I have not touched my fuel system....until next month

Here are some pictures of my Supra

rice lol

 

[Furyian]

I see what you mean about the NA cams ... They are already installed but in the next few months I really considering making the valve train stronger [s/s valves, titanium retainers etc ...] I will just switch back to the turbo cams. I just want to get a few miles on the engine before anymore major work. As it stands, the engine has less then 250 miles on it but after I break it in, I will take the advice and swap back over to turbo cams.

 

[Furyian]

I bought the car pretty much as it for 2000 so rice or not it was a better deal for me then the 87 Thunderbird Turbo Coupe project I had

 

[super.secret.supra.club]

wow?! $2000 huh. so what else did you trade for the car?

ed.d.

 

[gtsfirefighter]

Wheels are too small, I hate the bumpers but the motor alone is worth more than what you paid for it so good deal!
