88 TII Modification Advice/Overview!
ok guys here goes, i know this has been covered but do to the wide range of setups people are using im not getting straight answers by search or anything, but i have gained alot of common knowledge of what to run.
Ight, i have a 88 TII, that is in stock form, Pretty much all i want to do is add a k&n style intake filter, put on a aftermarket bov, and run a new exhaust which will consist of 2.5" pipe from the manifold throught a high flow cat and into 2 high flow mufflers(New pipe all the way)
some of my questions are as followed:
I am taking my injectors off to be sent to witchhunter tomarrow for cleaning, with the setup im running can i stay with the stock size injectors or do i need lets say 720cc secondaries?
Is the stock fuel pump good enough for my setup as long as it has been rewired or do i need like a walbro 255?
Also im getting a FCD of course, and do yall think boost creep will be bad? if so then some wastegate porting will be done
Boost gauge has already been added!
The big question is what other thing do i need to do other than the ones ive mentioned above to run this car safely, and how much boost should i look for?
I want any advice you can give me!!!!! i might be completly wrong about the whole setup considering this is my first time to mod a tII...
Add anything else yall think i should do, sry for the long post, im just trying to be informative...
Thanx you

hehe, the link in his sig will take you to a plethura of info on lightly modding, and highly modding your TII.
1. You should be fine with stock injectors on that setup.
2. Shoot for 10psi MAX
3. I woud recommend a walbro since although the stocker may have been enough in its prime...its probably well past that by now with age.
4. I would definetly port the wastegate if you're doing exhaust mods. This will not hurt you at all.

You can get a walbro 255 for 99 bucks shipped off ebay.....everyday. So you could get it, and not have to worry about it.
Boost creep won't be very bad at all with just a 2.5" exhaust....I started to see my creep when I went to 3".
But seriously....visit RETed's link in his sig....it tells all.

ive already did the regrounding on the coils, pressure sensor, and chassis and its still there, and i cant take it to redline without it like cutting out or something, also I havent installed the aftermarket boost gauge yet, but the when i punch it the factory one like peggs out, it that normal???

yeah, thats pretty normal, but then again Im talking about when mine hd the boost turned up......best install the gauge when you do these mods because you'll want to be able to accurately monitor boost in case you get any creep issues.
The cutting out you're experiencing just might be fuel cut. The FCD will take care of that. It might also just be sticky injectors.

I dont think the motor was ported, the guy i bought it from said it was rebuilt, then called back and said he was wrong and it wasent, and then called back again and said it was, so i dunno, i dosnet have any paper work that proves it so who knows.... it has 133K on it, it really good, im just thinking the injectors are dirty...

And i think i have hit fuel cut before bacuase, i stomped it in 3rd gear one day and i was pulling then just like violently stoped like it hit a wall or something, but y would i be over boosting when everything is stock??? well im pretty sure everything is stock, but there is no torque down low, so im thinking that my 5th and 6th ports arent working????

nothing, the turbo acts like the extra air (and far surpasses it).
The turbo motor is a four port design.
Anyways...I guessed that you were hitting fuel cut because you said that the boost gauge was pegged....well when its pegged (if these damn things are even accurate) you're probably right aorund 8.6psi where fuel cut occours.
Now, it is possible to be getting boost creep with mostly stock components. I've had it happen before. If I were you would go out and inspect you're exhaustand intake, maybe even snap a picture. Just because it was on the car when you bought it doesn't mean its stock, lets see what you're running.

Well i know the intake is stock, and i know for sure all the piping and the mufflers are stock, but the converters have those damn welded on heat shields on them but im pretty sure there stock too, i thought it was a 4 port design but someone on here, im not gonna say names convinced me that it has the 5th and 6th ports, i just never went and looked... thanx
anything else, ill try and get some pics if you want... im gonna try and get a compression test done today too if my friend comes through with the gauge.... O and the reason i said anything about ports was because, there is no pull on the bottom end at all untill you get up over 4K rpms.....

Compression check, you should have some sort of power.. max torque comes in at 3500 i believe? I don't know why you're hitting fuel cut with ALL stock parts, doesn't make any sense. I'd get a compression check personally.
