Newbie questions.

I just acquired a 87 t type. Always wanted one. The injectors that are on there are 009's which I just sent off to get followed and cleaned. TT chip that cam with car has #40 written on it. Shouldn't it have #42 on there? I would think it would make a difference. Pretty sure I'll have plenty of questions and I'm using the search as much as possible before asking.

Yes it should list #'s on injs and chip.

On the underside of the chip, you'll need to unseat it.

Maybe I wrote it wrong in my first post. TT chip I have that came with the is for 40lb injectors. The injectors that are on the car are 42lb. Is the chip suppose to have 42lb written on it or 40lb?

 

[gstewart]

Wouldn't it make a difference in the tune or driveability if the chip was burned for 40lb and my injectors are 42lb?

 

[Rafs-T-Type]

I would think it would be close enough. Not all 42# injectors are going to flow the same anyway...some would flow more like 40's and some like 44's. Just make sure the tune isn't leaning out on ya.

I talked to Eric last and he told me that with that 40# chip I have that it may run a little rich on top end. I'll be sending it back to him after I do couple mods anyways. Thanks everyone.

So how was the car running before you started doing "stuff"?

 

[gstewart]

Besides the overwhelming blue smoke, not that good but idled fairly decent. Leakdown showed 85% in #4 and 65% in #6. I could hear the air coming from crankcase. Both valve cover gaskets leaked heavily. Passenger side header bolts were only hand tight when I took them off and oil leaked pass the gasket into the header. Turbo shaft has a little play and looks like seals are bad. On both heads the valve stems were on the exhaust valve and none on the intake. I was like wth! Whomever worked on it last skipped a few beats.

Wow! Like somebody completely lost interest 3/4 the way through the project.

Don't know what they were thinking. Supposedly it was a shop in Mississippi or Alabama that did the work. I'm gonna try and bring my shortblock to the machine shop Saturday afternoon and discuss what needs to be done. I have a parts list written down and I'm also talking to a another machine shop that ports heads in Baton Rouge which is 3.5hrs away. It's more expensive than I anticipated but I'm intrigued about the potential of this motor. It's gonna take longer before I get it back together but I'm trying not to rush it.

 

[TurboTGuy]

These machine shops you speak of, these are shops that specialize in GN/TR's, or are they just machine shops you trust from past builds and/or hear good things about?

 

[gstewart]

They don't specialize in the GN/TR.
