faster 4k

[bigm]

your 4k because ur 4agze doesnt run??

[ke_70]

i was thinking a 3k head, gemini carb, advance the timing as much as you can or mabey bolt a turbo on

[Rice86]

so after all this, the best bang for buck to get that extra kick in the K motors is 98 octane fuel...everything else is a complete waste of time and money

[ke70dave]

the only real advantage that 4k's have is that they are very easy to work on, and you can get a complete replacement engine for $100.

which i guess is half the reason they are so popular to mod. they are essentially indestructible if you keep the oil and water up to them, which is prolly the other half.

rollaclub.com is where you wanna head for all your 4k needs

specifically this link for starters

[squish_m8]

just advance the timing as much as you can and run premium.

at the moment the 4k in my wagon pulls alot harder and smoother than the 4ac in my pano. so 4ac's aren't always better

[ae71]

4ac's have a habbit of running badly.

stock carb is poo.

while we are on the subject of junk motors, a 3tc are a top motor. lots of toque, quite tough, reasonably good head/ports for a poo motor.

guessing your on P's or something so a conversion of any kind is out of the question?

did you buy josh mcsides old one ???

[adm86]

i was thinkin a 5k in a ksev too but i was wondering if i went a 4ac would it bolt straight in like the 5k? cause if it didnt it would be harder to find another one if it blows as opposed to gettin ur hands on a 4k/5k
thanx adam

4AC will NOT bolt in like a 4k/5k in a ke70. 4k/5k is a straight swap because everything is already there. If you want a 4AC you'll need:

AE71 pedal box
4a crossmember either AE86 or AE71
T50 G/box crossmember
T50 gearbox
4a engine mounts/t50 gearbox mount (rubber)
4a engine
T series front half tailshaft onto your rear half

That's off the top of my head. I know I have forgotten things, but did you even try a search on this? 30 seconds gone from my time and I found you this.
