K8ZE - Colt Cams
-
ah crap nothing too serious I hope?!
-
Thought it was the appendix but apparently not! All tests back clear, very mysterious!
-
Weirdness indeed!
Have you seen how rear mount Turbos work? no need for expensive exhaust manifolds and good for where space is at a premium..
-
No man I don't, reckon I'll do some research while I'm laid up!
-
Hmm not sure how an air filter set up like one on a rear mount would hold up in Ireland. Lag would be a killer on a k8 too I'd say.
-
I've pondered rear mount turbos thought about chopping out tyre well and sheeting to make space.
No need for intercooler either.
But you need to rig up a remote oil feeder tank and pump.
But I couldn't work out where to get the feed back to the engine bay.
Would make for good weight distribution

So, picked up the KF01s today and got my caliper to 'em. I can't remember for sure which is intake and which is exhaust (anyone know the visual differences?) they measure
Exhaust - 43.45mm max height and a base circle of 35.21mm
Intake - 43.55 max height and a base circle of 35.20mm
Anyone know how to calculate the lift off of that?

Hi guys! I couldn't help but think this is a bit like the discussions in the US about KLDE and KLZE. Here, you can get a used KLDE for $3-400 and have 165 bhp immediately, with excellent mid-range, which is what street driving is about anyway. The turbo guys talk about 250-300hp with otherwise stock KLDEs. You might give some thought to this, as a 170 hp 1.8 is going to be a revver, with very little low end power. The KLDE has at least 10 ft/lb of torque more at 2500rpm than the 1.8 has at a peak of 4500. It makes a huge difference.
BTW, Lift = Height-Base Circle. That doesn't tell you much about overall specs, but it's a start.

I agree finding a KLZE is more difficult these days.
But KLDE's are easily available and often quite cheap.
–-----------
One thing I have found is that alot of engine importers are not clued up on what a KLZE is.
So I normally just go and have a poke around, the last time I went to Nippon who "Had no KLZE's in stock" I found 3 of them!! they thought they were just standard Millenia engines...
Some times places don't like you looking round so you have to talk your way in. The reason they don't like it is because they generally treat engines like crap while they are waiting to be sorted and they don't want you to see that!! often left open to the elements, often in a pile, yes a pile!! and often covered in all kinds of crap.
When they sort them they steam clean them and make them look nice before they give them to you.
The more you look like a dirty mechanic the easier it is to get a look round. Ask to look at all their millenia and MX-6 engines and just check for the right intake manifold and head codes, then pop out a sparkplug and check with a torch that the pistons are flat topped and your in.
I've got a pair of overalls that I keep for occasions like this, never washed em in about 5 years. They just assume your a mechanic and it keeps the prices cheap.
If your only after 200 ish bhp and don't really want a turbo i'd keep trying to find a KLZE.
or if you really can't wait i'd stick in a KLDE and turbo that. It would be easier and cheaper than trying to get a K8 up to the same bhp as a DE then fitting a small turbo.
or just fit a bigger turbo to the K8.
The cheapest / easiest route to 200 ish is still to fit a KLZE though.

you guys are so lucky to get the K8ZE. When I had my presso the "butt dyno" felt that the car could run laps around my MX3 (K8DE) and my MX6 (KLDE)
I just swapped in a KLZE in to the MX3 and the "butt dyno" was wondering why i didnt ditch the K8DE a LOOOOONG time ago..
The car even feels faster than the presso did…...
Ditch the K8ZE and get a KL anything!
Or just wait and see if you can find a KLZE. Your Rx7 will hold you over till then lol.
Its cheaper and more bang for your buck!
Im speaking from experience of years of wasting my time with the K8 power plant...
and just take logic into consideration. If it was beneficial to squeeze more power from the K8 people would have done it by now.......
Just my 2 cents :rofl:
