hey guys, i have a 93 FD and my bro wants to get a TII. we're going to go look at one tonight but i wanted to consult with you guys first. what should i look out for and what should i know before i go? it's a 87 TII for $3200. i don't know the mileage or any other info. thanks for all your help.

Get a compression check, check the turbo for shaft play, make sure it starts, runs, idles fine. Make sure their is no body rust or undercarriage rust. Open up the radiator cap when the car is cold, and start up the car, if you see bubble's the coolant O-rings are going and you should stay away. Find out what's done to it and if it was rebuilt, how long ago. Check that it boost's properly, if it's stock it should get up to about 6-7 psi. When I think of more I will let you know.

thanks for the reply rx7nub. i wrote everything down to make a checklist. i was wondering is there something "special" about the FC. i mean with the FD i know you should check for vaccum leaks, secondary turbo not working,etc. is there something i should look out for like that on the FC?

Rx7Nub

Uh.... I can't think if anything really that would be specific to FC's. Check for vac leaks... just like an FD, and uhhhhhh... I will think of more.

Rx7Nub

This should help a bit...

WOW, thanks for all the great info. the website is great. i see that you also have a 87 TII, how do you like it? do you prefer a different year TII? thanks again for all the great info.

Rx7Nub

I love it man, it was worth every penny in my eyes, I haven't ever driven any other years of the TII's, allthough I am fond of S5's and AE's. But all in all I am happy, and I am suire your bro will too.

The Kelly Blue Book pricing is fairly accurate.

BTW, there is no "secondary turbo" on the FC, but there is an actuator on the 87-88 models that lets exhaust flow to the secondary portion of the turbine at about 2500rpm, so it may feel like a twin turbo, but it is technically a single turbo.

The 87 and 88 (Series 4) TII's are nearly the same thing, with the main difference being that the 87 didn't have a spoiler while the 88 did. I'm not aware of any major differences in the Series 5 (89-92) TII's. I think the Series 4 makes a better project car because they are cheaper than the Series 5, they have a mechanical OMP, the suspension has a better feel, and they are lighter. Many people like the Series 5 better because of the round tail lights and better ducting on the front end. All of the TII's are good, so I think it's probably best to just find one that you like and not worry about the minor differences in trim. If the car is going to be used for racing, then you would probably want to make sure the car has an aluminum hood rather than a steel hood.

we picked up the car. it's a 87 tII with 131k, no leaks from the oil cooler, coolant looks good, all records, oil changed every 2500, clean inside out. the leather on the car looks great, no cracks, rips, etc. picked it up for $3000. white FC TII. i heard that these are hard to find.

Congrats
Just watch for fuel cut if you open the exhaust up!

smerkinseven

what do you mean???

ZenRXSeven

Without a fuel cut defender, the ECU (CPU, whichever...) will cut the fuel to the engine if boost reaches 8.6psi (or something like that). With stock exhaust it's not a problem because there's too much backpressure for the turbo to generate 8.6psi, but if you get larger pipes, then you'll be very likely to hit 8.6psi and beyond. Make sure to get a FCD when you get larger exhaust piping because fuel cut can be very harmful to the engine, so I am told.

Evil Aviator

The FCD is even more harmful if you don't upgrade the fuel system to prevent lean-out. Also, bypassing the fuel cut can lead to boost creep and overboost, so porting the wastegate is also a good idea. The fuel cut is there for a reason, so plan your modifications accordingly.

what mods do i need... also a 87 tii. when i say mods i mean you say upgrade you fuel system.

I bought a wolboro (sp?) today. do i need a fuel controller too? is that part the "fuel system upgrade" you refer to?

will my stock fuel pressure regulator be ok for this pump?

im a noob!

ZenRXSeven

A Walbro will be adequate fuel to run about 10psi, but without a boost controller and/or a ported wastegate, you'll get serious boost creep, so you have to be careful. A better boost gauge is pretty much necessary. If you're going to want to run more boost (and you will ), you'll need more fuel, so larger secondary fuel injectors are a good idea. And once your that far, you'll need some kind of fuel controller to tune the system. Basically, the more boost you want, the more fuel you'll need.

westcoasttuner

All I did on my 87 TII was a cone style air filter and then 2 1/2" exhaust w/no cats and straight through muffs. And damn it spools fast and unfortanly hits the fuel cut very quickly I have to be very carefull as I have no FCD yet. I am looking for alternitves because I dont like the idea of the motor not getting enough fuel. Anyone know of anyone that reprograms the ecu or other opitons? And far as a fuel controller what would I be looking for? And can I get a Walbro fuel pump @ schucks or any other parts house? And any suggestions on injectors?

Jaared

PM "FB II" ... he is making FCD's for $35.. i got a responce from him this morning and he siad they should be ready this weekend. Fuel cut is baddddd.. get a fcd until you can figure what you want to do about the gas/air thing. ill prolly endup getting a haltec... but thats another story.

i got mune off ebay for 90.00 new, thats cheaper than auto zone had a stock one listed(145.00!).

ebay it up... there is a guy named "sportcarmotion" he is sellin them and his feedback is good too. checkit out.

thanks for all the great info. ok so now we're thinking of going with a turbo timer, FCD, and a intake. is this going to be ok for now? a exhaust is next after that.

westcoasttuner

Ok stupid ? but is the walbro a universal part or do I need to look for a TII Walbro? And any sugestions on brand of injectors and where to get them?

Jaared

putting a walbro in a n/a is only for extreme apps, if im not mistaken. Thay giuy on ebay has them for for s4's and s5's .. tho I dont know how they differ.

I got the one for my year and im going to install it in the morning.
