ime only 15 and have had my c4 for 7 months now and haven't done **** to it. Ime not like all you guys and don't have a ton of money to do this i thought about putting a cheap lt1 in it or changing the intake to lt1. Any suggestions help full.

 

Wow, my first car was a '78 Cadillac that my dad picked up for $400! He handed me the keys on my 16th birthday. It was big and safe and UGLY!!! I totaled it 8 months later.......walked away without a scratch. That probably wouldn't have been the case if I didn't have all that metal and a huge 425 ci engine sitting in front of me.

Anyway, welcome to the forum! You really didn't say if anything was wrong with the car or if you're just looking to make more power. From your avatar it looks like a nice car. I know you're not going to want to hear this, and I'm not pretending to know your situation either, but if the car runs get used to the power it makes now before you start wanting more! The L98 is very torquey and can eaisily get you in trouble (or worse) without any mods at all.

To your question, by the time you spend the money to swap in an LT1 you've probably already surpassed what it would have taken to make the same power out of your L98. There is a lot to be had there, depending on what you're looking for. The LT1 intake conversion could be a good choice for you though. Check out the FAQ section (here: http://forums.corvetteforum.com/showthread.php?t=956100 ) for "Performance mods that do work". Some of those are fairly easy and "cheap" to do. Next search around on here. I've learned a LOT from just reading other peoples problems and responses to their questions. Forum member "Vader86" has a ton of info on the L98 and engine mods on his site. Just do a search for his user name and cick on his pic.

Bottom line, it all depends on what you're looking for. I seriously suggest that you get some driving time behind the wheel of your stock L98 before you just start modding based on other people's experiences. You may end up liking what you have already. But if the mod bug bit you already, definitely set a goal. Put a total engine plan together and then save up for that plan. Learn about what parts work well with each other. No matter what, there is going to be some $$$$ involved. How much you can do yourself will drastically cut down that amount. Also keep your eyes on the classified section here and search Ebay every once in a while. Deals come up all the time. Don't buy parts on impulse. Stay with your plan, stick what you save in a high yield savings and let it earn while you shop around and build enough up to buy your parts. Who knows, once you see your money grow, you may change your mind based on your budget at that time!

Again, welcome to the forum and good luck!! This is a great place to learn.

If it runs now leave it be
Drive it and be the coolest kid in school and as you get more seat time then you can mess with it.

C-4 and 15 = no driver License or Worst

 

It's been awhile, but I was young at one time. Back then I had a dream of having the fastest car in high school. Never happened for me, just as well. Best way to keep people thinking that your car is fast is to not street race. That way you dont lose any races. Just act sly and let them think you got a surprise under the hood. Do the cheap mods, then really lean to drive your car. My sugestion is to take up auto cross and learn how to maximize your cars strengths. You will safely learn how to handle your car in extream situations. It beats the heck out of a vidio game. Learn how to out drive your buddies, then invite them to compete in "your game". Good luck, Dave

 

First off your view of our demographic may be a tad flawed, i.e. not all of us have a "ton of $$"...

Secondly, congrats on your new C4 acquisition...

Before suggesting some cheap mods some info is needed:
-what year
-what tranny (a4 or stick)
-what rear gears
-is it now bone stock
-what is your budget

 

Me either, I rode the buses and bicylcles til I was 19. Missed

 

Good point!!

 

The best advice I can give you is if it is running well ...don' f___ with it!

No you can't just put a cheap LT1 in it...way more to it than that.

Work on freeing up the exhaust. No gimmicks.

 

91. l98 automatic. stock gears. its got some flowmaster mufflers that came on it . 500-1000$.

 

Take that $500-1000 and put it in a ING savings account. You'll get a few % interest while you wait for the inevitable breakdown. One repair and you're back to $0.

L98s are not worth putting gobs of $$ into. You can sell the C$ and add that mod $$ and buy a good C5 which will run circles around most L98s.

i as thinking the dual exaughst would be good but do u think it would be cheaper to get it made???

 

For now... Concentrate on school; especially English class.

RACE ON!!!

 

You said it, CFI!

 

OK, I agree that you should put aside some of that mod $$ for the inevitable maintenance.
There are a number of (relatively) low cost mods that will increase performance of your '91.
-remove the spare & jack for a 40-50lb weight reduction also drive with 1/4-2/3 tank of fuel (the total weight reduction here is ~100lbs==10chp gain and it's FREE)
-install a K&N air filter and cut the filter lid
-install a 160deg T-stat and switch
-cut back some stock AC Delco spark plugs, details on my site
-bump base timing to maybe 8deg BTDC
-install a 2 1/2" mandrel bent front Y and hi-flow main cat
-install an AFPR (adjustable fuel pressure regulator) and bump pressure a little to match the above mods

Would you be doing the mods, have a shop do them or have a friend help???

 

Keep it as is for now and put your $$ in the bank. If you want to do something.....clean it inside and out. Polish the wheels. Polish the aluminum suspension. This is cheap but looks great. You are only out your labor and it will take lots of it. Clean up the engine bay. DON'T spray it with degreaser and then hose it off!!! Use simple green on a rag to clean all the hoses and anything else that is dirty.

Check behind the radiator for S**t that has collected. To do this you will have to remove the top cover that fits over the radiator.

Lots of things for you to do and make her nice.

Welcome to the Forum.

 

Instead of worrying about modding it right away, take some time to detail it inside and out.

 

yea my dads mechanic hes got a 70 chevelle ls6. he dosent want to do anything tomy corvette but it dosent have alot of power it cant even burn out off the line but hes got a shop to do it at so name your suggestions.

 

If you want more power you have to know that it's all about intake and exhaust. The L98's intake is extremely restricted with the runners and manifold, so stick with the cheap mods like an airfoil, K&N filter, cut lid, and maybe a cold air intake. Save money for the big stuff later on, and try getting a job in your spare time if you don't have one already.

 

RACE ON!!!
