its not about max boost it can handle you gotta make shure anything about the factory boost you have the fuel to upkeep like a fuelpump/fuel pressure regulator/injectors or something to control it like an APexi SAFC but after i had fuel mods i ran about 14 pounds on stock turbo

Read the stickied threads on top of the 2nd gen part of the forum. FAQ for FC, What did the fc come with....Those have all the info you need and more. Also, use the search button on the top right. Research before you ask please. A lot of people will give you **** if you ask a common, simple question without searching.

It is a Hitachi HT-18-S, it has a water cooled center section. It has a unique footprint, not compatible with t3/t4 style. Has an internal wastegate, and it should be heavily ported if you are planning on using it at more than the stock boost level. It can be hybridized (sp?)to a 60-1 with different wheels and housings.
Hope this helps,
Vince

Just remember a stock 87 turbo 2 can only handle around 7.5 psi without going into fuelcut,stock intercooler is only rated to 11.50 psi before possiably rupturing.
Stock fuel system is only good for 10 psi(pump,injectors,ect,ect)
And last but not least,your stock ECU will only adjust fuel mix upto 12 psi effectively.
87 turbo was a T 1 7 I believe 5psi to 17 psi MAX
The car stock will handle 10 psi easily with the aid of a fuelcut defense,but I recommend you study up on your car first

intercooler is rated at 11.5psi... where did you get that from?
it ruptures over 11.5psi... where did you get that from?
stock turbo is a T17 and boosts from 5psi to 17 psi... where did you get that from?
ECU would NOT adjust fuel to 12psi IF THE FUEL CUT TELLS THE ECU ITS BOOSTING 7.5PSI ALL THE TIME
i suggest YOU study up on your car first

In his defense... even if you install an FCD... the AFM signal will tell the ECU thats its getting more air, and thus the ECU will adjust with more fuel... but.. IMO its not safe over 10 PSI...

The boost sensor does NOTHING to fuel delivery after the engine goes into + boost.
This is the same BS replies that a LOT of people used to tout when we first found out (by experimentation) that the stock ECU does jack to fuel delivery with the boost sensor.
Henrik (guys at RTEK) confirmed that there is NO FUEL ADJUSTMENT when the boost sensor goes over ~1.5psi.
So I'd suggest you should also study before making false claims.

yes the afm coudl compensate for it... but there IS a reason why people blow their motors by putting a FCD on there and expect it to work!
Get it right - you're already wrong about the fuel delivery and boost sensor relationship.
I theorize that it's low voltage to the fuel pump that's causing most of the blown engines, NOT the FCD...
Ask the people who have killed their motors - the majority will tell you it was during nighttime with the headlights on...

YOU were one of the ones that have said you cant expect to bolt a FCD and expect everything to be fine. I got that information from YOU.
Feel free to look thru some of your 17.2k posts.
if you want to say i am wrong, I suggest you correcting some of your older posts before you start barking at me.

I think YOU should go reread my previous posts.
I've always defended the use of the FCD, against the majority of people who are against it.

I have TRIED searching for it to prove you wrong. But when you post what seems like a few hundred post a day, it is NEARLY IMPOSSIBLE to find something you have said years - or even months ago. I am sure you know that.
I did spot an error here or there on your part... such as...

The stock ECU will prevent the car from revving that high when it's cold.

And you are going to call them out for giving mis-information and claim you never said anything of such?

AFM signal also controls timing - the AFM is the primary load sensor on the vehicle.
