Hey all i am new. I am Abe I have a 89 Iroc 350 tpi. The question is this. Will the lt1 intake work on my car, and is it worth it. Will gain gooh HP or should i just port the old one

 

No there is too much butchered modifications, Its not worth it you are better off going with a Miniram.
Page: Jmatlock he did it on his

 

Go to www.lt1intake.com. John Millican has intakes already modified or you can send one to him to have it modified.

no its not to much trouble i jus installed it i bought it from john m and its pretty easy ill have pics shortly i love the looks i have it ready to but it snowed next day after i finished so im holding off for it to melt i would encourage anyone to install it lots easier than the stock tpi and super ram from what ive heard later

 

I can't reply, I'm a little partial.

 

Someone with a large wallet obviously.

 

I'm think I wanna do the LT1 intake also, but I am curious if it will have any interference with aftermarket heads.

 

If drilling out the distributor hole and mounting hole, filling the old bolt holes and drilling new ones, and redesigning the cooling system is not much trouble, then please tell me what is much trouble? :hail:


And if your car needs an EGR valve (smog check) you are SOL.

BTW there are dudes running 11's with the LTR (no power adder), go here and see

Thankyou. It was a lot more difficult swapping from TBI to TPI and adding the DFI then it was going to the LT1. That was a peice of cake in comparison.

 

LT1 Intake Question:

What will the loss in torque and the gain in horsepower
( on a percentage basis) be from switching from a run
of the mill modified TPI compared to switching to the
basically stock sized LT1 intake that would replace it?

Does John Millican @ www.lt1intake.com do any
modifications to the LT1 Intake besides what
is necessary to convert from TPI, ie. enlarge the ports?

.

 

He enlarges the intake port to take up to a 58mm. throttle body, which is a pretty nice feature! I plan on ordering one of his manifolda very soon, as soon as money permits!

 

whats up abe this is Luke, mikes friend. Nice car (since you have the exact same car as me). Yes a TPI intake will work on your car all you have to do is modify the LT1 intake. goto www.lt1intake.com for all the info. You can buy a lt1 intake for $100-150 off ebay and then modify it yourself or send it off to someone that will do it for you. If you want I can help you out with that (since you only like 5 min away).

 

LoL RCR

thats what i wanna do, 305TBI -> 350TPI->Start Moddding!!


what are the benefits of lt1 intake? what about LT4?

thanx

 

BLUEIROC5.7, back to your original question. Yes the intake will work on your car, but as far as a huge hp gain, you need to swap heads and cam, to take advantage of the intake design. If you plan on modding the motor extensively it does make sense to buy the intake you will ultimately need. Remember, each time you swap out a component that is restricting airflow, look for next most restrictive all the way to the combustion chamber. With more air you also need more fuel, so that has to be included in the plan. Also, more mods dictate a change to chip parameters. Setting a goal for the car and balancing the mods is important to making you car fast.

 

To the guy who asked, yes you can mod the LT1 to fit aftermarket heads.
