That one looks fine. Just dont go with any thing cheap and you will be fine. Fuel lab and aeromotive seem to be the most popular. Now for installing it on a 4g63 I have no idea. Im guessing its going to be pretty hard on your car seeing how your fuel pump was so rusted/corroded and Im sure you probably have screw line connections like the 420a does, goog luck.

On the 4g63 it's not too bad. You just run the rubber fuel lines to the unit which is a piece of cake and then run the SS line from the unit to the fuel rail. Then of course a vacuum line. Ideally, should be piece of cake.

[ned032002]

Would I reuse the same vacuum line thats already on the stock FPR?

[SilvrEclipse]

You can as long as its still good.

[ned032002]

Well the stock fpr seemed to work fine so I could only assume that the vacuum line works fine.

So looking into a EGT setup. Not sure what temp range I'm looking for, the ones I'm looking at are some Glow shift brand ones. Here's what I mean by temp range.

and also a wideband from them too, but concerned of reliability? any thoughts

I have one of the Glowshift EGTs. Never had a problem with it. I was only seeing like 1200* tops on where it was at on the n/t setup. It's not installed on my new DP because I couldn't find a bung for it. But never had any issues with it. I would go with the 2400* one.

Never heard anything about the WB from them.

[SilvrEclipse]

Yea I would get a different WB. Something that you know works good and is accurate. I have never heard of anyone using this WB and I would be concerned with the accuracy of the unit. Also its not even that much cheaper, other WB are only a couple dollars more.

As for the EGT gauge, I would try to find one around 2000F. I hit about 1600F under high boost so you will want one to go to atleast 1600F.

[ned032002]

This may sound dumb but doesn't a EGT just help with finding the right AFR by watching the temp under certain conditions? Won't it just be redundant if I'm getting a WBO2 cause that will tell me exactly what AFR I'm at? Pardon my ignorance but learning as I go!

[david-b]

Ya nowadays EGTs are kinda useless. Still good to know what's going on when it comes to heat, but you really don't need one these days. Before WBs, EGTs were basically the way to tune.

[ned032002]

The reason I asked is because I have a 2 spaces as of right now for gauges. One is being used by the boost/vac gauge and the other is being used by a narrow band AFR gauge. So what I'm going to do is replace the narrow band w/ the wideband gauge, but was considering a EGT but I don't see the reason in spending the money if it's not necessary. I haven't read much about installing the w/b into Link but how involved is that? I'm going to do it but what all needs to be done to install it?

[david-b]

Nearly all Widebands have an output on the units that you hook up to some logger or device. On MegaSquirt, that output goes to the unit and reads it there. I want to say DSMLink is probably the same way.

[vanilla gorilla]

+1 just run the wideband, forget EGT.

[ned032002]

I mean when it comes to wiring it in, is it difficult to tap into the ecu wiring?

[ned032002]

Here's another dummy question, ebay oil catch cans? any thoughts?
