This May be a stupid question but, I'm getting a avenir sr20det with the ecu and the complete wiring harness. This will be installed in a 98 sentra 1.6. What I want to know is can I use the avenir ecu or do I have to get a us sr ecu?....I'm also getting the avenir maf.

If I were you, I'd pull out the entire engine harness when you junk your old DE, and drop in the Avenir engine as a complete unit with harness attached. Then, when everything else is positioned, just plug in your Av ECU and go. It seems silly to me to leave the harness in the engine bay anyway. :rolleyes:

I'd be junking be ga16de.

So just take all the crap out and keep all the avenir sensors?

so I don't have to change all the sensors over to a us sr20?

If I do change all the sensors over from jdm to us would I have to change the ecu and have jwt fiddle with it?

As I understand it, the only sensor you have to change is the temp sender that goes to the gauge cluster (not the one that goes to the ECU). As far as I know, the other sensors are the same, which is a nill issue if you're using the Avenir ECU to start with. When you have an ECU reprogrammed by JWT make sure they understand your block setup and they can guide you appropriately.

I have a 200SX SE-R and I want to go Turbo. I was going for the BB Engine but now i see there is a Avenir sr20det on the market now. TEll me about this new engine and what makes it better then the BB engine and what do it cost?

As I understand it the avenir ecu is obdI and My car is OBDII, which causes a complete headache if I want to use the avenir ecu,...Rewiring..:eek:.

So you have to use a 95+ wiring harness and ecu, send the ecu to jwt and get the det program in a few months or weeks as I hear.

To conclude my half-assed post does anyone know the price to the JUN products preferebly the strengthed head bolts...:D

if you end up sending your de ecu to JWT then I will more than likely buy your DET ECU from you as I am assembling parts for my Turbo next year. decadent01@hotmail.com Holla at a playa

What makes the Avenir a better than the Bluebird.

1) The Bluebird U12 202hp was produced from 89-91 U13 207hp was produced from 92-95. (The U12 is quite old).
2) Both BB and Avenir are interchangeable with USDM SR20DE
3) Both easy to get parts for.
4) Both have a T25 but the Avenir T25 is newer.

Avenir W10/W11
1) They are newer 96-present.
2) They haven't been sitting around for as many years.
3) They are easy to get parts for.
4) They are interchangeable with USDM SR20DE.
5) They are made with better technology, they are newer.
6) There turbos, manifolds, injectors have all been revised.
7) It makes the same horse power as the GTi-R 226 (stock).
8) It comes with 8:5:1 compression which means it's a little less laggy when off boost. (There is no need for 8:3:1 unless you plan on making a huge amount of boost).
9) It cost less than the GTi-R and about the same as a U12/U13 BB engine. I got mine for $1500.

:eek:

OK! easy.... now.

Disconnect your wiring harness from your ECU., pull out your ECU. Disconnect fuel and vacuum lines et cetera from the engine. LEAVE THE ENGINE HARNESS ON THE ENGINE. Snake the ECU connector back out into the engine bay, pull engine as usual. LEAVE THE ENGINE HARNESS ON THE AVENIR ENGINE. Install Avenir engine, reconnect vac/fuel hoses etc. Snake harness connector back to ECU location, feed back into passenger compartment (or wherever it goes) Reconnect Avenir ECU to Avenir harness.Oh Be Dee Who? Besides, if the idea of OBD systems compatibility really scares you, you're clearly not ready for a turbo installation.

:confused: Eveyone I talked to says your crazy.

I was gonna go this route buy I was told I could not,it would be stupid, why?, I don't know.:confused:

THEN, I was told I should swap out the harness for a sr20 harness and a 97 se-r ecu and get the jwt det program on it.

JWT says I should swap it out also..................for their program..:rolleyes:

I just want the damn thing to run RIGHT!

If I were to Buy that Engine what year and how much miles would be on it? And for $1500, I'm VERY interested in the buy. So please inform me on obtaining that engine.

Mndgy: Why am I the crazy one? It doesn't make sense to do anything else. You can either use a pre-'97 engine harness and a pre-'97 ECU, or you can modify your existing harness to use a pre-'97 ECU's sensors and use a pre-'97 ECU. I say, leave the Avenir stuff on the Avenir engine and plug the Avenir ECU into the car when you have the hard lines hooked up. Either way you go, you're going to have to gank or modify a harness; cope with it or go home.

I don't understand why everybody goes through all of these "disconnect injectors, sensors blah blah, label everything blah" when it really is as simple as leaving the harness on the engine and pulling the whole thing. The ECU harness is a seperate entity from the rest of the car's wiring harness, and there's no reason to divorce it from the engine just to do a swap.

SE R Madness: This really isn't appropriate for this thread. I'd advise that you use the "search" feature on this board and use (brace yourself!) "Avenir" as the search criteria. Any importer that can get Bluebird engines can get Avenir engines, it's just a matter of identifying them and negotiating a reasonable price. Go ye forth and make more turbo SE-Rs.

This is what I was initially going to do BUT if you look at the technical corner of the forum I was told it would not work by "chris @ sr20" and to do the 97 ecu and 97 harness by "MauiBlueGride", and ben at jwt. :confused: :confused: :confused:

If you can do a '97 harness, why can't you do an Avenir harness?
