i am looking at buying a 1988 corvette L98 for my gta its 1600.00 remanufactured and delivered to me. the ? i have is will my sensors all be the same? i have an L98 in their now but i want to know if their is anything i will need to change? please help i dont want any problems to pop up when i have the engine shop put it in.thanks for any help.

 

just wonderin.. why do you want to swap in a L98 from a vette if you have an L98 in there already? If its L98 to L98 all the sensors would be the same and itd be straight foward but whats wrong with yours? lol

 

the reason i want the vette L98 is it has the lighter aluminum heads. thanks for info about the sensors.

 

if the heads are all your lookin for, then if i were you id just get some used vette aluminum heads on ebay or something and clean em up, or buy rebuilt aluminum heads somewhere, and put em on what you have... then youll have money left to put into a bigger cam and the TPI to get that car up to par, as opposed to swapping in another L98 just for the gain in heads, somethin to think about. its all your choice though, good luckwith whatever you choose!

 

In his first post he said it was remanufactured. Since he didn't tell us, maybe his L98 is tired...

 

well you are correct i didnt tell you my engine is tired it has 114,000 miles and i need more power. i have changed my mind though im going with a engine builder in my area he is going to build my engine im going with aluminum heads and a holly intake the ? i have is what cam to go with? i want to use a stall thats about 500 over stock maybe a corvette stall.

 

The Corvette motors have a little hotter cam don't they? I could swear they do...

 

So do you mean you are going carbed? If so the Comp cams XE268 may be something to think about. It should work well with a slight stall. What rear gears do you have?

well looks like things have changed im not gonna have the money to do the engine now im soooo dissapointed.do you guys have any ideas how to make it faster im gonna have to buy 1 part at a time i allready have alot of bolt ons and mods but im only getting 7.1 0-60,15.3@93 not to fast.thats with one bald rear tire on the driver side though.maybe i need better traction its spins alot.

 

all L98 vette engines come with aluminum heads unlike the camaro L98...not sure what they come with

 

Get some better tires and get a N2O kit and I am sure you will be happier with the speed.

Brian

 

thanks dude but i really dont wanna kill my engine with N2o anyways.how the hell are you running 14.3s in the 1/4 mile i have alot more mods than you and im running 15s whats up with that???? i dont get it.

 

What mods do you have?

Ben

 

1. You wont blow up your engine if you install the kit correctly. They wouldnt be in business if all engines blew up with N2O.
2. 89s are tad stronger than 87s, a tad.
3. My car has 60k miles and has been babied for all 60k of them.
4. I dont know all of the mods that I might have. For all I know I could have a nice cam in there.

Brian

 

i didnt say it would blow the engine but i dont believe its good for your engine im just not into the N2o thing i want my power to come from the enigne. you are right though it is a cheap way to go.the only system i like is the zex system. maybe your right maybe i should get the boost.for now anyways.what kinda times would i get you think?

 

I am guessing low 14s high 13s.

Brian

 

what i wanna know is how all these other people with the same car and L98 are running low 14s and im running low 15s ? maybe its mt bald tire? maybe i will be running mid 14s with good tires? unless people are not telling the truth?

 

I dont know about the maf cars but the specs I have seen on the 91 and 92 cars list them as being supposed to run low 14's stock. You also have to remember that these cars were not all manufactured to very exact tolerances so some cars seem a lot faster than others. The tire and those 60 fts should help you out a bit. What rear end gear do you have. Do you know your altitude?

Ben

 

im not sure what the alltitude is im in new york.i have 3:27 gears,shift kit,ported plenum,afpr,under drive pulleys,180 thermostat,160 fan switch,8*timing,air foil,flowmaster exhaust 2 1/2 inch,gutted cat,400hp fuel pump,a.i.r. removed,spare tire and jack removed,kyb struts and shocks.i going this week and put corvette servos in and maybe a home made induction of some sorts.

 

So you dont have headers and you have 2.5 inch exhaust. If you change the exhaust and get a high flow cat or put a pipe through one instead of being gutted it should help you out a lot. Most of your mods arent stuff that will help you much speed wise. Some cars had those gears stock, but they are decent. Does it still spin both tires or is the posi worn out? Ported plenum can help a little, pulleys people usually dont gain much, the fan switch and thermostat wont do much, timing can help a little, 2.5 inch exhaust(a lot of 350's had 2.75 stock) need something bigger, fuel pump wont do much, air pump removed wont do much, removed some weight(100 lbs equals about 1/10th, shocks and struts wont do much and shift kit may help a little also. It looks like you have a decdent setup, but you are choking it with that exhaust, and if you get new rear tires that should definately help, especially since they say every tenth you gain in your launch should be 2 on your quarter. Tires and exhuast should see you a good improvement. Maybe some rear suspension upgrades.

Ben

 

how do you launch? I hard launched before and only mustered between 14.9-15.1, but I did free mods and learned not to really punch it until about 2200 rpm and pulled a 14.6! if you're tires are balding and you hammer it from a dead stop, you are going to spin for quite a while. I've got 108xxx miles on my engine and it runs as if it were brand new
