Correct. The factory ecu contols shifting so it will run parallel to the haltech and run the transmission.

I agree. That is the reason I sold the supercharger and am going turbo. The TRD supercharger kit is set for 6psi to work with the stock ecu Current plan is Borg Warner 8374 efr turbo, 6 boost twin scroll manifold, Haltech ecu, Bosch 550 cc injectors, some kind of intercooler, supra fuel pump...

I like the header. There are very few choices here in the US. I never dyno'd the truck with the supercharger on it. It was the early Kazuma case that I ported, 3" pulley, methanol injection upsream of the supercharger, the CX header and 3" exhaust, small top mount intercooler. It could...

I know they don't get much love on this forum but I have a CX racing header on my 80 and it has held up really well. I did hi temp coat it even though it is stainless just to help the low quality chinese stainless last. Also, I had to port it right at the exhaust flange because it was really...

Great info. That graph shows what a newer ECU can do for the 1FZ. I am thinking your intake is the one that is after the US spec intake used until 1997. The newer 1FZ has a higher power rating but I doubt it is from the newer intake. All of them suffer from a small-ish throttle body and...

I have a big expensive pile of parts waiting to be put to use, eventually. I had been held up on the turbo manifold decision- do my own or buy. I committed to a 6boost manifold. It will bolt to a Borg Warner 8374 EFR turbo, 550cc Bosch injectors from Five-O-Motorsports, Supra fuel pump, some...

I'd like to be able to push around 15 psi, at least on the dyno. Looking for close to 600 hp at the crank so that should be around 400 at the wheels on an 80. Not sure I'd leave it there. Perhaps run lower for a while, but not sure.

Yeah, no codes would be cool, just not sure it can be done.

In the spirit of "pics or it didn't happen " Here's the heart of the setup- 8374 efr twin scroll goodness.

I suppose that's what they mean. I wont be using the stock maf since the Haltech uses a map sensor so the ecu won't like that.

Season is over, I'm just slow. I have a spare 1fz-fe engine that has 100k less miles than mine (only 180,000) so I am going to put that on the stand, tear it open and check everything over, new head gasket (possible machine for mls gasket), reseal and move forward. I pulled the trigger on a...

As soon as the "season" for my 80 ends. That would be like October at the earliest or maybe November. When I start making real progress, I will keep updates going on my build thread for sure.

Meeeeeeeee too!

Yes, both the haltech and factory ecu

Here's the Boomslang Fab harness. I stumbled on these guys when I was searching for the AEM patch harness. As @scottryana had posted elsewhere, AEM offered a patch between the factory ecu and the factory harness plug- perfect for diy splicing. Unfortunately, they didcontinued it. Not...

I have been silent on my own thread because my project is silent- for now. I removed my supercharger (sold) and bought almost all the parts for a turbo build. I didn't want to be without my 80 this summer so I am running NA for now. This fall, I intend to kick it in gear again. I have...

Good point about their unit being locked, if indeed it is. I'm not runnung 300 miles away every time I would want to mess with the tune. I really don't believe that is the case but the conversation didn't get that far either. Not sure why the ECM can't come with at least a baseline for the...

I did Inquire to Wolf (Australian) about their standalone setup. They have a plug and play harness for the 80 and it does control the transmission, but, you must have them set it up, according to who I talked to. I had a conversation with the rep near me (Wisconsin iirc so semi close to...

Thanks, I'm not in a rush but at some point, I want to do this. I am trd supercharger/intercooler now and it seems o.k. but I would like to go more boost. Possibly to the point of putting the trd on my stocker 80 and going turbo on my new to me 80- then I'll definitely need it. I was thinking...

T That's encouraging
