K&S Posted August 12, 2011 Report Share Posted August 12, 2011 So I'm thinking of a 7k into my ke70, I wanna know any shit fights with this conversion, all I know of so far is I have to use the 4k sump, is there anything else? Does anyone know anyone who has done this? Sorry if this is in the wrong section, just asked here first before the ball gets rolling Any help appreciated :) Quote Link to comment Share on other sites More sharing options...
SLO-030 Posted August 12, 2011 Report Share Posted August 12, 2011 4K sump wont fit on the 7K block. 7K is about 11mm wider than a 4K block Quote Link to comment Share on other sites More sharing options...

K&S Posted August 12, 2011 Author Report Share Posted August 12, 2011 Well the sump seems to be the only problemo I'll call a few wreckers n c if they got one Any of you guys know of a 7k sitting around?? Quote Link to comment Share on other sites More sharing options...
altezzaclub Posted August 12, 2011 Report Share Posted August 12, 2011 Whats the power per cc like in the 7K?? Will you end up with a large torquey motor suitable for a van or a forkhoist, but no fun in a car at all?? Quote Link to comment Share on other sites More sharing options...

Will you end up with a large torquey motor suitable for a van or a forkhoist, but no fun in a car at all?? I gotta say, why does everyone come to this assumption? Has anyone ever been in or driven a 7K powered KE? I've had the opportunity to go for a few extended rides in KEturbo25's 7K 25. Yes, its turbo, BUT the thing is a complete power house OFF BOOST! On boost is a completely different story. Quote Link to comment Share on other sites More sharing options...
B.L.Z.BUB Posted August 12, 2011 Report Share Posted August 12, 2011 I suppose you just gotta build it right. Quote Link to comment Share on other sites More sharing options...
SLO-030 Posted August 12, 2011 Report Share Posted August 12, 2011 That's it. But really, everyone seems to want to shut the 7K down before it gets its chance to prove its worth. Look at Gavclassic's KE17 with the 7K. Tuned set of sidedraughts and a decent set of pipe and its making 103rwhp. Name another K engine you can do the same to and get similar results, without spending heaps on a massive cam, super high comp and super high octane fuel while keeping it N/A?

I've got one. Pulls through third like a 4k in second! I think mr. altezza was making an unfounded assumption. Quote Link to comment Share on other sites More sharing options...

Sorry if this is in the wrong section, just asked here first before the ball gets rolling Any help appreciated :) hi i have been running a 7K for the last 5 yrs in my 69 KE15 sprinter. Fitted the engine myself without any great drama. You must run the original 7K sump modified to go over the cross member(the sump is a lot wider than 3or4K). Also being a stroker motor it is slightly taller.for a standard engine mine has the sprinter twin carbs. port size is the same. as we drive to sydney every year for motorfest I installed a taller diff (3.55 to 1) which gives me exceptional economy. hope this is of some help Cheers Lou Quote Link to comment Share on other sites More sharing options...
Taz_Rx Posted August 13, 2011 Report Share Posted August 13, 2011 Ah, that worth a mention - the port sizes (both in & ex) are quite different between 7ke and 7kc! Quote Link to comment Share on other sites More sharing options...
altezzaclub Posted August 13, 2011 Report Share Posted August 13, 2011 Well, the stories are cute, but I haven't seen any figures on bhp/L. I'll look it up. A bigger motor does produce more power, but they tend to be less and less efficient. It's this sort of curve- 7K, 1.78L, 80bhp, 45bhp/L. Wiki 5K-U, 1.49L, 70bhp 47bhp/L Townace, englishauto.vl 4K, 1.29L, 65bhp, 50bhp/L Wiki 3k, 1.17L, 60bhp, 51bhp/L Wiki Quote Link to comment Share on other sites More sharing options...
Jono.C Posted August 13, 2011 Report Share Posted August 13, 2011 (edited) I don't really tend to care about figures to see how an engine goes. I'd rather actually get in and drive it! I've driven a ke36 with a 7kc with a 32/36 and an exhaust and that thing hauled. I don't really care what it's bhp/l is because the torque when you plant it just makes it worth it.
