The 7

My 87 na can not go any faster than
100mph

its gets there pretty quick but then i
shift into 5th and it just freezes at
4 grand and 100 mph
thats fast enough for me but
this is a problem right?

What is wrong with my car is it
something major or is this just
how it is.????


Thanks for your help

Don't put it in 5th. Redline it in 4th first.

Cats and/or stuck 6-ports..

Open up the exhaust (gut cats - new exaust), open up the intake.. I get 120+ out of mine pretty easy, and that's all I've done to it.

I've hit 120+ in 4th gear @ 6500 RPMs. She was still pulling HARD. I bet I coulda taken it to redline (8k), shifted into 5th and hit 140 .

..... but I pussed out

I've once had a similar problem with my 90 GXL. The problem was caused by the cat partially restricting the exhaust flow. If the cats are still on your car, than this is one of the first places that I would look.

Write down what your tire sizes are and the rpm you were at when at 100mph. Theres something elso going on here.

I can hit 120 with the top down on my 'vert.

If you're redlining 4th gear you should be @122mph...
