i have a 99 ex coupe. just caged it real nice tucked everythinggg the whole 9 yards. im trying to go fast this year lol i have a z6 and a ls both mint both complete mint trannys. which would you build? i noticed everyone always drag races eg hatches. am i gonna loose out on this ek coupe shell? should i get a 5th gen hatch? vitara the single cam for the price and numbers ppl ahve been doin or forge a ls?

 

With a turbo setup, good tune, and the proper fuel, these are the 'safe' ranges for the given engines. People have made more power than what I've listed, but realistically, i think these would be the goal numbers to shoot for.

Stock D - 220whp
Stock LS - 300-350whp

Vitara D - 400whp
Piston/rod LS - 450whp

The D series is going to be cheaper all around, but it will make less power and have a different powerband than the LS. That's not to say it can't be fast, but all other things equal, the larger displacement LS (and the fact that its a dual cam) will ultimately allow it to make more power.

Your best bet is to search the Forced Induction forum. There is a 100+ page Turbo LS thread floating around...it would give you ideas for the setup as well as realistic goals for the setup

 

mainly worried about the shell. will there be a significant difference between ek coupe and eg hatch in 1/4 mile / street

 

My buddy's 93 hatch pulls my 97 coupe and there both stock, bout a car length n a quarter

 

Compare weights of the hatch and coupe you are talking about OP and then go from there. I am sure the hatch will weigh less than the coupe.

 

If you use the LS, get a different transmission.
