My KLZE Festiva Build Thread

[Gforcefd]

IF this isn't already, it should be stickied! Great thread, and a festiva pioneer in my book. Can we buy advance tickets for rides?

^^Thanks for the info! i'll have to do some playing around with it, i'll try to get them working properly at first then worst case senario i'll tie them open :lol:

This is good info for me to know before i buy an ECU, which ECU woud be best for the stock KL-ZE set-up?

It depends on which intake manifold you use. The curved neck manifolds have different VRIS points than the straight neck manifolds. The rest of the information I have stolen from mx-3.com

kl31/36 - straightneck VRIS
k8 - k8 intake VRIS
k8 with millenia probinator chip - curved/millenia intake VRIS
kl01 - klde intake manifold VRIS

Curved neck Vris is;
ON OFF
Vris 1 3750 6200
Vris 2 4250 6200

Straight Neck Vris is;
ON OFF
Vris 1 3800 6600
Vris 2 4800 6600

To get the proper vris points, you would need to do 4 dyno runs.

One with both VRIS closed
One with both VRIS open
One with VRIS 1 open
One with VRIS 2 open.

You need to manually keep them closed/open.. and also disconnect and plug the vac lines running to the actuators.

Overlay the torque curves so that you can see where they intersect, and those will be the optimal vris points.

It would be beneficial to do the dyno runs if you modify the engine and would like as much torque as possible out of the motor throughout the whole rpm range. Open VRIS is good if you plan to stay in the High rpm range all the time. If you plan on using the rest of the rpm range I would suggest keeping VRIS and getting the opening and closing points set properly.

You should totally get a Lexan hood made... This engine needs to be seen by everyone!

"That vacuum piece" is for your VRIS. The KLZE has VRIS it just opens at different RPMs and that is what provides you the extra power in the different rpm range. It also what gives people headaches when they swap the KLZE and don't have the right ECU. I think you are right about it being in a different spot on the KLZE intake, but there are two of them on each intake, so one might move but the other might end up in the way. In my mx-3 with the KLDE they are right up near the firewall, It was a bear hooking up the connector because I had to do it from below the car, but had to reach to almost the top of the engine with virtually no space between the engine and the firewall.

I wouldn't worry too much about the vris stuff if you plan to boost. I would remove it and tie the butterflies open. My dd probe and my turbo probe are this way. Plus in your situation it will free up room and you won't really notice a difference in power especially in a festiva

This is a good idea and i may do this even before i boost it just to free up space at the firewall :lol:

Cool. I was looking at the clearance pics. Do you think you will need a FMS hood to actually clear the engine since it has the raised center part? That would be sweet. Funtional hood bulge, not just for show.

It actually looks like it would clear a stock hood which is cool!!



I made up two brackets today to re-attach the rad support, if i get to it today i post pics

[Maxtiva]

He allready have a FMS fiberglass hood and he just bought a carbon fiber one from festivaWES

^^I'm not sure about that seam on the firewall, i don't think the KL-ZE has that vacuum piece on the intake to get in the way (I hope) so until i get the KL-ZE home and in my festiva, i'm not going to worry about that part yet

I'll 2nd that!

God this is gonna be boss when it's done! perhaps, the ultimate sleeper??

[Lmcclure]

that is a beautifull site, you have changed my mind yet again on what kind of swap i want to do...how much would you have to have to make some custom mounts? also is that pinch weld on the firewall structeral or can that be takin back a bit?

[Damkid]

Yes they are :lol: i'm considering knotching the frame if its too tight
