Good meeting you Bryan, good to meet Mike and John face to face. Mike thanx for letting me use your space, tools, knowledge.
Bryan maybe that scanner will come in handy for me too. if i cant find why i'm running raggy.

86 IROC

Yep, works on TBI too. I used to find it helpful on my old 88' 1500.

Well Im currently watchin I think 4 or 5 scanners on ebay so we'll see. My mom talked to a guy who owns a video game store and they need some part time so I think I might have a job finally. Then I can start doing some nice stuff to the car which you will appreciate Mike. I see runners, intake manifold and cam in our future lol. Its the distant future but still.

What you were saying about sticking with the 9bolt Bryan, so I should just keep it and put the 3.42 gears in? I have no problem doing that. Down time on the car would be a lot shorter.

3rdGenWillie

looking into oil press. sending unit. should be above oil filter. intermittent low oil pressure. makes the car run like crap. yeah, i know it's an lo3.
scanner cant see that though.

86 IROC

Yup, you can buy a set of 3.45's and have them installed. If you saw the difference in size between the axles on a 9 bolt vs. a 10 bolt - that would be enough alone to convivce you. Plus, you have a very clean low mile car that hasn't been abused. You never know what you might get buying another used rear.

For right now, until you get more mod money - get a TPI manifold gasket set, some carbide dremel bits, diferent grit sanding barrels, etc. Then port your stock plenum & base. Hell, you can even pick up a spare base manifold cheap and work on it in your spare time. I'm going to do mine next month. With patience, you can really lean on a stock manifold and make it work until you buy an aftermarket piece. I have a Edelbrock Vortec base, but no heads yet - hence why I'm going to port my stocker for now. I'm going to leave the internals of my car alone and remind some people how fast a bolt on car can go. My old cam only IROC used to run consistent 13.00's, it was a heavy pig compared to the 91'. I'm confident I can go just as fast or faster without a cam in this car.

Oh ok kool stuff. I will most definetly have to to go that route. I thought about getting a new intake manifold and having the plenum ported. It would be kool to do it myself jsut need to get all the stuff to do it with. I need to start working on me intake box. Just need a heat gun.

3rdGenWillie

Called Hawks Today. They have everything I need. Dr. side fender, dr side 1/4 spoiler. and they'll use my UPS acct#. $220.00 shipped

ewwewwnotme

Good stuff Will. You going to get the car repainted or just paint the fender and spoiler piece?

3rdGenWillie

well, trying to get rid of dents. paint later. need to fix driveway.

ewwewwnotme

Just bought a UMI strut tower brace from the group purchase. 15% off so I got it for 150.

3rdGenWillie

nice! ur car have wonderbar stock? which is lower brace.
you order online or ph#, what did they tell you on ship date for that new stb?
these things tend to take awhile so i will watch it and order wonderbar later.

86 IROC

Wow, I didn't realize they were so exspensive. I think the one I used to have on my LS1 car was like $99 new - not on sale. Is it a 2 or 3 point brace?

I need to dig through my crap, I think I might have a wonderbar I saved off of one of my old cars. For some reason GM stopped putting them on these cars after 88' or 89'.

ewwewwnotme

I dont believe it has a stock wonderbrace. They said shipping would be a few weeks due to it being a brand new product which Im not minding its no big deal. I ordered it online. Its a 2 point for TPI.

Kwiksilverz28

I got mine from BMR too. It was like $100. BMR is in tampa area and gives cash discounts....

theimpaler68

all this talk is making me jealous so many things to do and no time or money to do it... at the moment! i am thinking suspension first though. make the tires stick better first then give them an excuse to let go.

3rdGenWillie

it's an adjustable 3 piece 2 point stb. they just got onboard w/ this item. they dont have a brace for carb/tbi yet. every company has diff. prices, umi has so lower prices on 1 item bmr another.
looks like if i cant find whats wrong with my oil pressure, me and wifie will be having the "my car needs new motor talk" always an excuse.

ewwewwnotme

An excuse will always do it for ya. A lot of TPI stb's arent real attractive to me but when is saw this one I had to have it lol. The bmr one just doesnt look good imo.

theimpaler68

the hotchkis one looks good but way too over priced i think and Will, have you looked at edelbrocks stb for your tbi i think they have one?

86 IROC

I had an Edelbrock on my old 86', and MAC used to make a 2 point - they were like $69 new. I have access to a tubing bender, I may just fab up brackets and make my own. I used to build all my own suspension & chassis stuff back in the day. I need to get back to that and start saving some of my hard earned greenbacks.

ewwewwnotme

UMI just called me saying my card was accidentally charged today instead of when the group purchase ends. So what they said is mine will be the first one out and if the group purchase doesnt meet the quota I still get the discount. Either way it works out in my favor due to them charging me early. Im not complaining lol.

3rdGenWillie

the last umi gp, the same thing happened. it's not bad for them to make accidents, cause they have ur money and maybe a new happy customer!

car is sucking down gas like a pig. how to install mech. oil gauge ? there is plug for it where?

86 IROC

No plug, you're going to have to find a spot where you can tap in with the line for the mechanical guage, no wiring required. See if there is a brass T on the back of the block behind the distributor.

Kwiksilverz28

Check obvious stuff. Last plug change? Check engine light work/on? Bad o2 sensor?

I don't like mechanical oil guages. That little plastic line is a time bomb waiting to happen. Get an electric one....

86 IROC

I suggested the mechanical guage just to test the accuracy of his stock guage, not as something permanent. Plus they make copper line kits. It will rule out a bad sender or inaccurate guage. For his sake, I hope I'm wrong, but it sounds like worn cam bearings.

Kwiksilverz28

I was thinking main bearings as a worst case....

Good idea with the cheaper guage

3rdGenWillie

no t on back of motor. sensor comes out above filter.
last plug change, late feb 08. check engine light good, throws good code. o2 sensor dont know.
yeah plastic line is easy to melt if routed wrong.
gm gauges are 2nd rate new. approx 114k mi on motor.
on this car i read that fuel pump is wired into oil press sender for some reason( cheap gm)
let car idle 5 min maybe more. ran it up as high as 3500rpm to see what gauge would read. car idled right, press. was at 30-31psi at idle, normal. sounded right.
pulled air filter base, looked at tbi injectors, at idle, constant "spray" is that right? my truck seemed to have much less fuel at idle. never had problem. at 200k mi.
shut car off loaded kids up, drove down the block 2 blocks away, same ****, low idle. car ran bad.
can i hook up mech. oil gauge between block and sensor and keep it under hood?
also read, i said car has been sucking fuel like a pig.

ewwewwnotme

On my car I have the fuel pump oil switch or some mess like that that cuts off the fuel pump when the oil level drop below the sensor to avoid engine damage. That might be what that is. Oil was coming right out of the plug on mine when I had that crazy oil leak back in february. That might be what that is.

3rdGenWillie

now low oil after warm up, all the time.
