Well, I've been contemplating replacing my Celica for years. I could sort of put a child seat in the front passenger seat, but because of how the convertible is made (starts as a coupe in Japan, and modified in California), there are no upper child seat anchors. I wasn't really OK with that, and I wanted something....more. Lots of cars have come across my list for the first few years. I wanted 2WD with decent handling, 4 seats, modern enough for automatic locking retractors and upper anchors, a manual transmission and at least 200 hp. I was watching for Jetta GLXs, Maximas, Contour SVTs, IS300s, and even some BMWs occasionally popped up in my price range (i.e. CHEAP). One car would pop up frequently, and it ticked most of those boxes. But the engine was a can of worms I didn't want to deal with. I've pretty much decided about a year ago, that this would be the replacement. But what engine? So I've been researching, and bench-building (like bench-racing...but....yea). Finally, one came up for exceptionally cheap a few weeks ago. Engine/transmission (and more) were already removed. I had to bring my own wheels. and it's got some rust. But, at the very least, I can start testing things in real life, and the purchase price was worth the headlights alone...And it's got a title, and a sunroof, so it might be worth saving. So, Tall Dan and I went for a drive... 2022-03-16_07-29-48 by Numbchux, on Flickr I've never realized how small these cars are. It really is similar dimensions to the Celica. And somehow, similar interior/trunk space, and a much bigger engine bay. Back seat isn't much bigger than the Celica, but with modern child seat anchors, and the goofy suicide extra-cab doors make them fairly accessible. It's not a family road trip car, but at least I can take the kids with me (specifically, I can drive the fun car when I have to bring the kids. I've drove my Celica once in 2020, and not at all last year). So then comes the engine question. LS is the obvious answer. That's been done hundreds of times, there are several companies making kits to do it. But, my focus is on a light engine, and I don't need the power that an LS is capable of. I had an aluminum 5.3 truck engine second on my list, but I wanted something more interesting. 2022-04-06_10-37-36 by Numbchux, on Flickr Here is a 2GRFSE oil pan mocked up in the RX8 engine bay. This is the longitudinal RWD version of the Toyota 3.5l V6. I can use this oil pan on the transverse version of this engine (2GRFE), and with some factory parts use an R series 5-speed RWD transmission behind it. Likely an R150 or R155 truck unit, with a few R154 Supra parts for better gearing. This engine was insanely common in Camrys, Highlanders, Rav4s, Siennas, RX350s and ES350s, as well as the Lotus Evora. My plan is to get an AWD donor vehicle from Copart... This engine is a fairly common swap candidate into MR2s, so there is some performance support (Toyota offered a TRD supercharger for awhile). And with headers, an intake and a tune, they regularly make 300rwhp. I plan to run it on an ECUMaster EMU Black, which can use the DBW, and VVT, and output the CAN information for the power steering and gauge cluster on the RX8. This is a very long term project. If things go well, I hope to buy a donor car next winter and can really work on it next summer.
