RT Posted June 3, 2005 Share Posted June 3, 2005 extractors, cold-air induction, side-gap your sparkplugs um.. MSD Blaster coil, new silicon plug leads, electric radiator fan, clean out your water system.. thats about it for cheap thrills. Quote Link to comment Share on other sites More sharing options...
DavidTheCreator Posted June 3, 2005 Share Posted June 3, 2005 extractors, they go pretty cheap. if your brave bore it out yourself with a dremel Quote Link to comment Share on other sites More sharing options...

MAD626 Posted June 4, 2005 Share Posted June 4, 2005 Make sure its serviced and tuned right to start with. Check spark plugs/leads/points/air filter etc are ok first then after that i would go with the extractors, electric radiator fan, elec distributor?

Defective Posted June 5, 2005 Share Posted June 5, 2005 if its in a corolla put it in a starlet. if its in a starlet alrready then throw away your interior, spare wheel, jack etc etc. join a local rally club, and buy some old lexan windows, basically make it as light as poss.... not quite what your asking though....

AE25 Posted June 12, 2005 Share Posted June 12, 2005 from factory specs a 5k have more torque.. not power. which is better for acceleration in normal rpm range. so yeah a 5k would be a nice upgrade. i believe 3k-b has the most factory power. no 3k-b are not the only big port! alot of ke20 3k have a single carb bigport head. my factory 3k-b ('75 ke25) is a smallport twin carb... many variations aye. also swapping heads round willy nilly can bugger things up. there're many differences in the chamber design and piston dish. sometimes ya can end up with 13:1 compression or something stupidly low. later jdm 4k like after '83 have a twin squish head and dished pistons.. early ones have flat pistons and more cc in the head chamber... different pushrod heights.. yada ya. unless you know what ur doing.. then better off skimming the std head or getting a thinner gasket etc to up compression and maybe do some mild porting to get er flowing. imo first thing after a tune up (plugs, fluids, filters, cap, rotor, points, timing, blah, is replace the peeshooter exhaust with 1.3/4 - 2". put a foam or oiled filter on it and some cold air ducting from the front wouldnt hurt. electric fan. cams and heavier valve springs make some good gains after exhaust and intake done. and yeah raise compression. can upgrade carb to something slightly bigger. could lighten flywheel for some better acceleration.... the usual shit. speed cost money, how fast you wanna go?
