JDM Injectors VS stock

Matrix733 · Post by **Matrix733** » April 15th, 2006, 3:14 pm

Hello fellows, i have a JDM k8 (not klze) that am about to put in my 1993 gs. The stock engine crapped out. I have to use my stock intake manifold as the JDM intake has a straight neck.

I have the ECU for the JDM engine. Can i just use the JDM injectors on my stock intake since I have the ECU for the JDM Engine? The rails and injectors look the same but the resistance could be different. Am trying to keep everthing as JDM as possible.

Thanks.

If it`s a K8, I dont think it matters.
Never heard of a straight neck K8 before...

The K8 was also used in the Eunos 500 and Mazda MS6...., that's where the straight-neck would've come from

what makes you think the injectors are different? but yeah, you should be sweet anyways

If it's at all possible, I would try my darnest to utilize the J-Spec IM and TB. Retain the J-Spec ECU. Using the NA-Spec IM may give some different performance results based on posssible different VRIS points. Small point I know, but it would be nice to massage every HP out of it. This wouldn't be a KFZE would it?

Both a K8DE and K8ZE should have the same injectors, red tops. Check the rail and if you see a little red piece exposed towards the top of the injector, then it's the same thing.

the mx3 was called either an autozam az3 or eunos presso in japan.

one had the same k8 with 100kw..

the other had a k8 ze with 107kw.

either way the k8 sucks balls.

Ok, I have included some pics. The Stock Intake on the left, JDM on the right. I wish I could keep the JDM intake. It seems smaller and looks better for some reason.

When I flip the intakes over, (pic below) I notice the vris points are a little different. The one on the stock manifold has the left one blocked and there is a connection on the one to the right.

However on the JDM Manifold it does not even have a connection on the right one and its uses the one thats blocked on the stock manifold. I guess I need to figure out how to hook it up on the stock manifold as it is on like the JDM manifold since am using the JDM ECU?

P.S. The injectors looks the same except the fuel rail connection for the hose is a bit longer so no biggie just that I have to use a shorter hose.

What do you fellows think? Do I need to make the connections on the stock manifold just like it is on the JDM version by moving the vris connections underneath the JDM to the stock?

No. Leave it alone.
