I'm seriously looking for some 460cc injectors and the larger fuel pump to go with them. Who has the injectors that just swap out easily with no cutting or modifications? I'm now ready for them and the fuel pump to run them.

Got to have some more horsies workin' under there!

I dunno if you meant 420cc injectors, but you can use the ones out of a Mercedes 450 SEL from 1974. I've heard those work. I'm not using them (I'm messing with SVO injectors), but I think on zcar some people were also saying they used RX-7 injectors which are 450cc. Check the archives there as the post was a few months ago.

I believe those are not N/A rx-7's its the turbo ones you want

 

I went to my neighborhood O'reilly's and they have the Merc 450SEL injectors for $40 each + $4 core charge. I don't think I can beat that price anywhere so I ordered some.

Now, what about the fuel pump? What should I go with there? I'm running 17-19 lbs boost. I don't think the stock fuel pump will keep up with that even with the 420cc injectors.

Suggestions anyone?

Got my 420cc injectors today. Waiting on the fuel pump and throttlebody to arrive. I still need to locate the spacer needed to install the throttlebody.
What about the Z31 ignition swap? I saw sleeperz's posts about that on hybridz.org. Looks like something I want to try. Does anybody know about how much those parts should cost?

Are you using the 240sx tb? I got my spacer from a guy on HybridZ for like 30 shipped or so.

Yeah, I got the 240sx TB. I talked to Juan at JSKinnovations.com about the spacer. He had those cool annodized and colored spacers on eBay awhile back. He said he will make some more in the near future.

Who did you get your spacer from? I don't know if I want to wait much longer to get one.

Hey, I'm also looking for an electronic boost controller that I won't have to give one of my nuts for. If anyone sees anything or has anything, please let me know.

Thanks,

I got my spacer from Tim, he's one of the mods on the boards over there. I think his screename is tim240z or something like that. If you're looking for cheap electronic boost controllers, you can try searching for the older model ProfecB's. I've seen them selling brand new for as low as 285, they could be cheaper now since they're discountinued, but they're awesome for boost controling.
