I've been searching for a good 5.0 TPI 5 speed car for quite a while, and they sure do seem hard to find. Am I just having bad luck. I have finally decided to restore to stock a 5 speed 1990 IROCZ that had been pretty well trashed by the previous owners. It was originally a 5 speed car but had been changed to Turbo 350/stall.

What a pain!

 

buy my car, it's 5-speed :P

 

Sellin it?? huh huh huh huh?????

 

The G92 5-speeds are even harder to find.

 

Well, I found mine sitting on a local carlot in Feb 2000. I was searching for about 1 minute before I saw the ad in the paper. I went to look at the car, saw it had a 5 speed and bought it on the spot. First time I ever drove it was to the bank to pick up the check. I think I was lucky because I have yet to see another one.

 

When I was looking for my car (in Australia), I looked at a couple of convertibles, both were 305TPI and 5 speed, and one was 305TPI and auto.

Is the 5 speed 305 TPI an unusual combination? What about in a convertible?

 

I've been looking for the car in my sig for 4 years in the NE area.

 

I've got a g92 5.0 tpi 5-speed (whew that's a mouthfull) I just kinda fell into it, am I correct in thinking this is a hard to find car? I have yet to see another like it. (It's a t-top formula btw)

 

There is a 305/5speed 1LE formula here in the classifieds, and on autotrader.com.

 

I have a 87 5 speed TPI car that I am not willing to sell, but they do seem to be rather uncommon in good condition...

It seems to me there are more 5 speeds in the V6 and the LG4/LO3 cars than in the LB9 TPI cars, I do not know why, but it only seems like I see more of them.

Is the 5 speed 305 TPI an unusual combination?

Unusual? Not really. Just not many built.


What about in a convertible?

Even rarer, simply because of the low number of convertibles built. Sorry, mine is not for sale.

 

I ordered mine to get the 5-speed, and it's got the G92--and every other performance option. There weren't many built because most cars were ordered by the dealers for their lots, so they usually had automatics to appeal to the "everyday" driver(and because it upped the sticker price). They rarely stocked the 5-speeds. So if you wanted a 5-speed, you probably had to have it ordered for you--and argue about it, lol. "I don't care that you'll knock-off the price for the auto, money's NOT the issue. I DON'T WANT AN AUTOMATIC!" For real, I'm not exaggerating, lol.

On the other hand, if you went to a Ford dealer, nearly every Mustang you'd find on the lot would have a 5-speed. And since you can still buy a new Mustang, tell me who was more in touch with its customers.

GM blames the f-body's extinction on the growing popularity of other cars and pickups, but the reality is that GM killed it all by itself. People with $25,000 to $30,000 for a car were NOT shopping for Camaros or Firebirds. The traditional "young person's car," was no longer affordable to the young person.

Sorry for going off on that tangent, lol.

 

There are many other reasons why there is no F-Body right now and for the next few years, not necessarily that reason as there's much, much more to it. (although it did help) Now, back to Third Gen only discussions.

 

 

NOw that you mentioned it, my Automatic was a dealer ordered car, and my Manual was a special order.

John

 

I got my '91 from Bruce at Hawk's Third Gen. It's hit in the front ,but easily fixed. It has the 5.0 5speed combo w/ R6p performance package.My son's '92 Z28 has a auto and it was dealer ordered. Chris

 

ive got a black on black on black formula with a 305 TPI 5-speed. from my understanding they are pretty rare cars. not sure if im sellin mine or not..

pics = http://members.cardomain.com/brynnda

 

the answer is yes, i'm selling it

 

Lucky for me, the fella that ordered my car canceled his original order when he heard the 5sp TPI was coming out. He ordered a loaded TPI 5 speed with G92. Lucky me.

 

I bought my 1988 IROC-Z convertable new in March of that year. I found it in a dealers showroom and it is a 5-spd with the G80 limited slip rearend and G92 performance axle ratio.

I am not sure if the dealer ordered it that way or it was a special order and the original buyer backed out. The original extended warrenty book has someone elses name on it whited out.

Well my 1988 IROC G92 LB9 5-speed lacks 1AZ, but it seems to be a custom ordered vehicle; very close to a A4U G92 Camaro but it doesnt have RPO A4U. No Air conditioning (C41 standard heater), hardtop (no CC1), DX3 decal and stripe delete (first year available) and of course G92 and LB9. There is a switch inside for fog lights but there doesnt appear to ever had any installed (I didnt get any with the car, no fog light wiring either). It took me forever to find a car like this and the car has seen better days but it runs great (93mph trap speed 100% bone stock) and I wouldnt trade it for anything.

 

I'm glad then that I did by my 5speed TPI convertible.

Not that it really matters - in Aus, all 3rd gens, especially convertibles turn heads. I guess I will just have to keep her for a little bit longer!

 

Vinnie,
Is your car a right hand drive?

This might sound really odd, I really would like a right hand drive F-body.

John

 

"Is the 5 speed 305 TPI an unusual combination?"

"Unusual? Not really. Just not many built."

Any way of knowing how many 87 tpi 5spd g92 were built. I understand that 87 production numbers are useless. If so, and an actual number is not known, then are quantities for 88-92 tpi 5spd g92 available? Maybe could then estimate quantity for 87.

 

Hi john

Yes, the car is right hand drive.

I have posted some pics in the convertibles board - "your convertibles" sticky with cosmedic modifications made during the right hand drive conversion.

Let me know if you want pics of specific areas.

 

there is a 89 iroc 5.0 5 speed with 40,000 miles on auto trader.com for 7995.00.

 

I have an 89 Iroc R7U 1LE 5.0 5 spd car. Ultra rare black on black. Rarest ever one of 73 and very few were black.

 

Sorry I used the word "rare" it won't happen again.

 

mines also a black on black on black..

 

unusual yes, Im so glad I changed from an auto to a 5 speed in my 87 Z/28. I get a lot of compliments on it I think just cause its a 5 speed, a lot more compliments once they found out I was the one that changed it, little do they know how easy it is!

 

5 speed convertibles were very hard to get in '88. It was too late in the model year to order one and we didn't want to wait 4 months for a car so we had the dealer search 6 states to find it, and he came up with only one...in yellow with 179 miles and never titled...we almost didn't buy it ..we didn't like yellow much, but it has really grown on us over the years, and we would not change the color for the world now. My brother had a 5 speed black IROC vert, and he let my wife drive it and that was it, she had to have one, I loved the fact that it had the same style spoiler as a '70-1/2 Z28 and I would only go for the 5 speed, so we took it in yellow.

 

Just checked the Auto Trader here in TN and I found 1..not sure if it's what you are looking for....'89 RS, Blue, 305, 5 speed, T-tops, pw,pdl,cd,spkrs, full exhaust, slight body imperfections, well maintained....$3195.00...Check www.us.trader.com or www.tradertennessee.com Good luck finding a t-5 car ...I love mine

 

Wow..there is also a '92 25th anv. RS vert ,billet wheels, for $3995.00 it's a V-6, auto though.

 

I too searched forever for an 88-89 Iroc with the LB9, T5, and the G92. Finally found one a year ago, but the body wasn't too good (doing much better now!)

 

What is the G-92 option ? My car has 5speed and t-tops..great combo...does not seem to be a popular combo or is it just me not seeing any ?

 

Try this... https://www.thirdgen.org/cgi-bin/rpo/index

I think you will find all the answers to most any questions young Padawan learner

 

I disd the math once and from what I remeber---44% of IROCs form 87-90 came with the 350.

That leaves the LB9 5 speed/automatic or LG4 (or LO3) auotmatic or 5 speed.

Looking throught ebay and my canadatrader.com site I don't see 305 TPI 5 speeds very often at all. See alot of LG4 and TBI formulas--alot more then TPI

 

Thanks...I have th 3.42 if thats what it means !

 

Performance rear axle. I'm not sure if that RPO means a specific gear ratio or not tho. I have that option and my car had a 3:08.

 

my dad's car is a black on black 91 t/a with the LB9/5 speed combo... he wasn't looking for a car at the time but he stumbled into it and couldn't take his eyes off of it... and since then we haven't seen many other cars like it...
i'm jealous of all you G92 guys, though.. this car didn't come with it ... but it does have the rpo for posi

oh, and judging by the fact that it has no options (except for rear window defrost and a cargo cover), it was probably ordered by someone and not ordered by the dealer

here's a pic

 

I am not really sure what G92 means either, my 87 Formula has the 3.42 Borg & Warner 9 bolt Performance axel, 5 Speed, and the TPI, and T-tops, it has every option for a Formula that year except the rear defog (originally a Flordia car) ... I think originally the G92 it was a Camaro only option in 87, and in either 88 or 89, the firebirds also started getting the option... I have seen a Formula with a "wonderbar" and I wonder if that is part of the G92 Options... All I know is the G92 usually came with the performance options...

John

 

I have the wonderbar, but I thought that was something that came with all the Irocs...?

 

wonder bar came with all IROCs. My former TBI IROC had one.

 

Ouch, TBI Iroc... that must've sucked!

 

Anyone know quantities of 5 speed IROCs from 85 to 90? Or know where to find this out. And, any further breakdowns by engine available?

Frankly, a TBI IROC sounds pretty cool being unusual. If it is unusual. Everybody will save the TPIs, and the TBIs will end up as rare.

 

hahha Yes---it did suck. It ran a 16.2 bone stock---I even removed the IROC decals just so people wouldn't think IROCs are slow (obviously some are though)

A long time ago I had a 5spd TPI IROC with the 3.45s---that rocked. I don't think people give enough credit to the 305 TPI 5 speed. They are often over looked in favour of that automatic (no fun!) 350 TPI cars.

 

I'd take a 305 TPI 5 speed over a 5.7 auto any day! Doesn't the LB9 T5 combo put more power to the ground anyway?

 

I had a 89 TBI IROC-Z convertible. That was a rare sight. I havent come across another one yet.

 

No.

LOL to the guy that took the IROC stickers off because he didn't want it to speak for IROC-Z's in general.

 

Yeah well I was trying to do my part to make IROCs look good

As for the hp to the ground...it might be close but the 350s torque would still be alot higher.

iroc22--how many passes have you got with your new car?

I remeber my 87 (thats the TPI 5 speed 3.45) was horrible to launch. NO weight transfer. Best 60ft was 2.2 and I think that was with the rear tires at 20psi. Keep working at it and you should be in the 14's for sure.
