Total Engine Redo?

curt · Post by **curt** » October 10th, 2007, 9:47 pm

Hey, I'm thinkin about swapping out my K8 and throwing in a KLZE. I've been searching the forums and the internet, but haven't been able to find certain performance parts for the KLZE. The main thing I'm looking for are headers. I've noticed many people have got Pacesetter headers, however when I look they are not made for the MX3. Which ones would fit the KLZE, and what mods (if any) would have to be done to get them to fit. I was looking at these headers (eBay Item number: 260167582371). Please check them out and let me know what you think of them. Also, I plan on getting the KLZE a bit before I'll install it and I'm planning on doing some work to it. If you were in my position, what would you mainly focus on doing? I plan on powder coating the valve cover (will this hold up to the heat), port & polish and possibly camshafts (anyone know of good cams?), and most likely the gaskets. Again, any input is greatly appreciated, and sorry if I missed something that was posted on the forum. THANKS!!!

Any headers for the klze will fit the k8 and vice versa. All K series motors have the same bolt pattern. Pacesetters will work, and alot of people like ssautochrome headers. Check the faq there is a good post on headers in there.

As for the engine rebuild, colt cams are sopposed to be a good upgrade. You can find more information on probetalk.com. Do some research over there and you will find endless amounts of info. The probe guys are doing alot more with kl motors than alot of the guys here.

Pacesetter headers are suppose to give the most power, but require some modifications. The Y pipe on them is a pivot design which is crap!, if you do get these headers get the shop to weld on a flex pipe. Probe/MX-6 V6 are the ones you should get.

For the KLZE, mainly do as much as your wallet can handle. GO on Probetalk.com and search on there for building up the KLZE.

Apparrently a flex pipe can have quite a negative effect on your exhaust flow. With a small engine like a B6, it shouldn't make much difference, but with the KLZE your N/A power is getting up there and exhaust flow will play a larger role. Yoda posted on this recently.

I believe a ball & socket flange would be a better option. It allows the flexibility that your exhaust system needs, without interfering too much with the flow.

I am doing this as we speak.. I already have the headers.. I got the ssautochrome 3 or 4 years ago.. install was a little tricky with the motor in the bay.. but sence you are going to get the klze it will be much easier.. I would got with the ssautochrome...but its up to you... as far as the cams... If you have a curved neck klze then just get some kl31 cams off the fourm here or probetalk.com.. sometimes ebay.... if the straight neck ze then just keep the cams that you have.. as far as port and pollish you can knife edge the intake and clean as much junk out of the manifold as you can... you might look into meriatic acid.. there is a nice write up on probetalk about it... for upgrades on the motor.. replace as much as you can.. .. water pump, belts, oil pump, plumbing, timing belt, plugs and wires.. .. as much as you can.. it will save you in the long run.. also pull you oil pan and clean that too.. It might be full of junk.. and replace all your gaskets if you take anything apart!!

Awesome guys. Thanks for the input. Also, would a better rad be a good idea?

Ah not necessarily, if yours is wrecked in anyway ( fins are all bent and leaks) then yeah replace it.

Okay, what would be better? Get a KLDE engine and turbo it, get a KLZE and no turbo or get a KLZE and turbo it (how much boost could you put in). How many HP could you get each up? Thanks!

Okay...now you're starting to ask questions that have been covered millions of times. V6 FAQ and search feature.

People here will start to get really annoyed with this. Laziness is not taken kindly to. A genuine need for help, when one has made attempts to help themself is taken kindly to.

After looking and searching the FAQ for about an hour, I haven't been able to find something that really answers what I want. I found that you can put 14psi on your DE. I'm just guessing that you'd be able to put around 8 or 9 on a ZE. Is that 14psi boost without replacing the pistons and rods? How much HP can you get each up to? And also, in your opinion, is a ATX to MTX swap hard? Yes, I know theres a FAQ on it, and I read half of it. But what do you think? And if these have been answered in the FAQ and I missed it, Im sorry. If you think an hour worth of searchin is lazy, I dont quite know what motivated means to you.
