Building Up My 4K, Need Help

[goose101]

hey guys, I'm pretty new to rollaclub, i just got myself a ke70 corolla and I'm lovin it, but i want to get a bit more power out of it without doing an engine conversion, so far I'm getting some 10:1 compression pistons, 277 degree cam, twin barrel webber carby and some extractors and exhaust system, but someone suggested to me to get a 3k bigport head and shave it down a bit, but i don't really know much about it, just wandering if anyone else here has done it? and if so how much can i shave off? and basically i want to get as much power as i can out of the 4k without turboing it so any other suggestions on how to make it faster would be appreciated, and also i havent bought any of this stuff yet and am still looking for it, so if anyone has any and wants to sell i may be interested, cheers.

Side-draught carbs will do better if you really are after every bit of cheapish power. A single DCOE or a pair of them, twin SUs, Dellortos...

 

Don't forget to lighten the flywheel and get the whole thing balanced.

 

How big in bore do you want to go? You could hunt down some piston that will make it 1450cc or anything out to the 5K 1500cc.

 

The head you will need to measure, both chamber volumes and area, to calculate how much to skim off to get your desired compression.

 

Same as I did, but you're after more grunt I think.

Best to keep compression on a N/A motor 10:1 or less, todays fuel is ssssssshhhhhhhhiiiiiiiittttttteeeeeeeeeee! :(
