T Montague's 2zr swap - '08 m/t sedan some extra info

[ern-diz]

Sooo cool

Yeah, kind of a bummer. If I had the 1.5L it would be just over 2000. Not sure if the loss of HP is worth the lower competition weight. Makes it all the more interesting though to look at higher redline or different cam profiles for the 2ZR, so I'm very interested to see what you come up with on yours.

To stay in the 1.5L bracket, have you ever thought of Frankesteining a 1NZ with FXE internals, to increase the compression ratio to 13:1 and having forged rods. Also the FTE's redline is 8K, with that information, you can safely get the rev limit moved to maybe 7500 in the 1NZ, and put that in you HB? And then use the xB1's transmission, which has a final drive ratio of 4.31 vice the Yaris' 3.72. The gear ratio for 1st to 5th and reverse are all the same.

There's some restrictions on internals and compression ratios that I haven't delved too deeply into, mostly because that's outside the scope of the build for now. It has a C60 gearbox in it now, not sure what final drive offhand. My DD hatch has the 4.3 final drive in it (and a custom configuration of OEM gear sets) and it's a real detriment on long tracks because I lose a LOT of top end speed.

Wait, wasn't this thread about someone else's car? =P

OOPS! I had to look at who the OP is, sorry I got you two top notchers confused...

Restriction on internal swap to change compression ratio? Where's can I look for the handbook for these kinds of events? How much do you guys invest into this? I might dive deeper into this hobby once I retire from the military.

I'll start a thread about my other questions.

On with the weight reduction thread.

MWR was supposed to have the header ready to ship as of April 12th...unfortunately there will now be a third delayd/t Covid with an approx update of two months. No idea if this will even happen in time for this season but my fingers are crossed.

I was going to instead, pull the trigger on a EMU Black standalone ECU as this will lead to more hp gains than virtually any other bolt on. After sitting on it for a day or so I have decided to wait on the ECU until late October once this track season is wrapped up. The issue is there is no plug and play harness for our application so I have to wire in the ECU myself and then create a base map to allow me to drive my car to a tuner and have a proper tune made.

I am not confident that I can have this completed in 4-6 weeks so that my car is running properly to be taken to the track. I don't have hours on end where I can work on this and I already have a new concrete porch and stairs I need form and pour this month. Long story short, it won't be enjoyable if I have crazy pressure to get this done and the last thing I want is for my car to not run and miss out on a whole track season. I need time to pour over the EWG's and pin outs for the Xd ECU and make a spreadsheet of what wires I need. This in itself is a lot of work and wiring in an ECU is not something I want to do half assed.

I really hope the header becomes available soon for 2021 but at least my car should be making some good power for 2022 and I'll have an awesome winter project to keep me busy.

I did try and purchase the extended BJ's today but I heard back that those are 2-3 months out. I may be able to pay a bit more and have them here in 3-4 weeks but the reality is a ton of parts are backordered.

It is what it is, but I'll be happy if I'm still able to turn some hot laps this year.

No worries, just didn't want to completely derail his thread. =)

I'm building mine for SCCA Road Racing. https://www.scca.com/pages/club-racing

glad you're still working on this bucket, Trevor!

I'm about 2h from MWR if you ever get stuck....i know they only ship UPS/fedex so you get hosed coming into CAN

[tmontague]

Thanks Barber, I appreciate the offer. I will eventually find out what it costs to ship a header once they eventually get stock back in.

I hope you and the family are doing well!
