i am looking too install my new runners this week,so i was wandering if anyone had any troubles putting them in or if the directions were pretty straight forwad and how long it took you .i `d appiciate any info on your jobns, thanks

 

http://www.slponline.com/inst/20004.pdf

there are the instructions for the install off of the slp site.

basically as far as i known its a bolt off the old ones and bolt on the new ones. the hardest part some would say is getting to the bolts that go across the underside of the plenum to the other runner.

I had my stockers off and didnt have any problems as long as i had an extension and swivel.

 

did you feel a difference when you put them on?
did you use the stock bottom and just changed the runners?

just wondering if i should do this since i am doing work on her car now

where did you feel the power increase, bottom end, mid, top?

thanks

 

i have thiu instuctions ,but was wandering.thanks for the info,and i should be installing them this weekend.my little honda`s been down so i havent got around to work on the z

 

I dont have them, I still have the stock tpi. I had my tpi off to delete the egr.

 

I put them on my 90 5.7 GTA back in 00, pretty straightforward install, just make sure you align the runner bolts correctly and tighten, took a few hours, but I also installed an AFPR and ported my plenum also.(don't forget to do that if you haven't already) I noticed a tiny decrease in off the line throttle response, but a slight gain when I stabbed it out on the highway. My motor was all stock with just SLP catback,chip, and freemods at the time.

 

You won't gain any torque, but the idea of the runners move your power curve up a few hundred rpm. More revs, better for racing because you can build the motor with larger cams and have more gear later on. Ported tpi kicks ****.

 

I hope you at least port matched the runners. The runners I got brand new from SLP didn't line up with the plenum correctly and would've caused some major turbulence.

 

i got some slps with port work done to them...i did more work myself....also did more work on a ported plenum i got....i hope this will give me a good boost in power over my stock tpi setup with a 52mmtb....i hope to also install my parts in a week or so!! parts are all port matched i have done more work to them since these pics....made them more smooth and get back down in the runners more...also did work on the base side of the runners...hope it makes a good diff in power!

355tpipickup,

Let us know how much of a sifference your runners make.

 

Having had my slp's on and off several times recently, here's my two cents worth of advice.

Check for interference in a few places, and keep your Dremel grinder handy. The bottom of the SLP's might rub on the base, misaligning the screw holes, particulary that little round lumpy spot. If you are using dressy allen head bolts check for clearance at the two center manifold bolts. They usually smack the bottom of the runner. I'd grind the manifold rather than the face of the runner.

I had to place the runners in position, catching two bolts slightly, then get the fuel rail in place. Otherwise the runner flange hung up on the rail. The valve covers may need to come off to reach the bottom runner bolts. I have taller Edelbrock's on and they were in the way.

Check for clearance for the injector harness clips at cyl 2 & 7. They are hidden behind the curve of the runner, and can be tough in install without clearancing the back of the runner. YOU DON'T WANT TO HAVE A SIDE LOAD PUSHING AGAINST THE INJECTOR!


Did you remember to connect the sensor under the plenum? Run the vacuum hoses under there too while you can. The brake boost hose is easier to attach to the the back of the plenum BEFORE rather than after the plenum is mounted. Hand space under is cowl is at a minimum.

Time wise, it's two to three beers and several new vocabulary phrases.

 

how did you like the gain? was it worth the trouble?

 

Nice and clean job on the aluminum,

Ive seen some pretty hacked-up jobs.. your's seem
to be gone about the right way.

The real secret to a good port job is attention to detail
and most importantly .. PATIENCE !!
