I like this kit, but I want to know if it will work for my car since it's a 1992! I know the site says it's only for 1987-1989, but is there really any difference from 1989-1992 on an L03 motor?!? If this can't work, can someone point me in the right direction for a intake manifold swap for a 1992 L03 motor? Thanks, here's my link....

that kit is misleading. the holley throttle body has an adjustable fuel pressure regulator in it already. then they give you another one. so your buying two parts. you have to run an adapter to fit that throttle body on that manifold. it looks like it comes with it, its a spacer/adapter. But most people say that is too much throttle body for a l03 and your better off doing the ultimate tbi mods in the sticky thead above. Focus on headers and exhaust first. This stuff is really unneccesary until you have higher flowing heads to where you'll need a higher flowing throttle body...and to make it run right you'll need to do chip tuning...which they dont tell you there either.

OMG - for $1000 you can replace the entire car!

You need to pass on that bigtime! You'll get nothing but headache out of that.

Do you have a particular problem your trying to solve, or do you just have a need for more speed?

Well, I be done headers and exhaust cutback, I want to still see my car reform better. I thought intake manifold was the next best step! I'm not for certain I want to get the whole kit anyways, maybe just theintake manifold. BUT, would the intake kit work on a 1992 L03?!?

Until you get heads, and then tune a custom chip - your wasting your time. And, for the cost of new heads, you could swap entire motor. I'd be saving my cash for a LSx swap - you can swap an LS1 now for under $2k if you snag a used LS1 motor.

Ok, but would the kit work on my engine or not?

I'm guessing not, since it doesn't state your year. I think the reason is the heads/intake bolts pattern. Some year heads have a different angle on the 4 center bolt holes for the intake. I'm guessing this intake uses different bolt hole angle on those 4.

This kit seems to be for those 305's that were carbed, and thus had different heads with different angles on those 4 center bolt holes. Especially since it's the entire kit - it looks like it's meant for someone that wants to switch from older carb system to TBI system (since it's the whole kit - because it would be silly for someone that already had a TBI unit to buy the kit and thus pay for another TBI they didn't need.

If your dying to get a different intake, look at Weiand - they have several nice carbed intakes that flow decent and are less expensive than an Edelbrock brand, but just as nice. Then, you can use a TBI adapter to mount your TBI unit on a Weiand square bore carb intake. But again, I'm telling you - changing intake will net you nothing but less cash in your wallet - you will not get any better performance - your still dealing with the super restrictive swirl-port junk TBI heads.

It will work on your car but is a waste.

Thanks guys, you were a big help! I'll look at Weiand intakes, and look into new heads too. I want to keep my L03 for now, so I'm not worried about putting money into it to make it perform decent. Do you have any particular heads to suggest for the L03? Thanks

Also camaronewbie, could you give me a good idea of a Weiand intake to look at with a part number please!

Ok it it not for a carb conversion. 100% sure of that. Why? Its a edelbrock tbi manifold, tbi etc. thier is no computer there no wiring harness and it does not say that. It is a tbi top end kit. It only say to 89 because the holley tbi that comes in the kit is for up to 89. it also states for a truck. the truck switched to a dual stud air cleaner in 91-92 I believe. so therefore thier is a different throttle body # for that. that is why the kit is specific.

In the end the kit is worthless to you. your one paying for a adjustable regulator, when one comes with the new tbi unit. 2, a tbi unit you do not need. and 3 an intake that is going ot make minimal gains. as well as any other intake you put on (carb intakes will require a carb to tbi adapter plate). Therefore take your TBI do the ultimate tbi mods to it, buy or modify to an adjustable regulator. and be done with it.

BigRog thier are a ton of threads on what heads people recomend on here. Do a search and you'll find them.
