Interesting... kinda like learning how Lotus had a hand in the development of the Quad-4, because of the success had with their DOHC I-4 2.3L in rally racing, when it was fitted into the Vauxhall Chevette. Imagine it: A lightweight, fuel-efficient engine that produces 150-HP in a car that weighs barely more than 1-ton... THAT'S the Vauxhall Chevette 2300-HS(E). And we almost had it over here, too!
Yes, you’re right, its a Pre Family 2 engine from Opel , Im from Brazil and u can do a stroker engine using 1.8 or 2.0 crank from Family 2 , in US common on J platform like Cavalier 4cyl Saturn and others , some mods to the crank needed for the distributor and fit others rods , actually u can go to 85/86 mm pistons (3.38”)
With some mods is possible to go from 1.4 to 1.9 L , but 1.6 blocks requires less mods to do, because they’re a bit larger on crank case , possible go to 82mm stroke (3.29”)
The most difficult thing is find very low pistons to keep the R/L in good numbers, here we use to do with motorbikes pistons , but only for Natural Aspirated application
@JB-ci6bn ours are an aluminum case copy of that 4 speed so the bellhousing should work. Our 4 speed won't take much hp before it starts having issues though so I might keep my eyes out for more Isuzu T5 bellhousings. The Borg Warner t5 will only have issues with super high RPM shifts.
I believe a very curious information you may not know is that here in Brazil we have a “preparation” for the OHC (As we call it here because Chevrolet strongly advertised about the over head camshaft design) called “misto quente” It consists in mounting the F2 engine head from the 1.8 or 2.0 8 valve or even 16 valve to the original chevette’s engine block, because the oil and water channels are extremely similar it’s something feasible, tuners usually reach 120-160 hps NA, and up to 8000 rpms, before the crankshaft reaches failure because of the balance, depending on how extreme it is, excellent for a NA with factory 70-80 hps I believe the book you mentioned (Which I have and it is excellent) talks a little about it, Chevrolet engineers actually used this in rally competitions, because there were no regulations against changing the whole cylinder head! Making the chevette the winner because of its advantageous RWD layout (Most of our cars were already FWD at the time) ruclips.net/video/xzT7evfx-Ro/видео.html Here’s a good example!
Do you want to know who designed it or who casted it? It was most likely cast in at least 3 different foundry's. Different company's used different combinations of internals to meet their needs. This engine probably has some old origins and got pushed all around the corporation. Personally, I would prefer if it where Japanese over German.
Once Opel left it to the Brazilians they cast their engine there in Brazil. The North American versions were cast here stateside after they figured out what needed modified for the US market. The US 1.6s were sent to Venezuela and marketed as 1.8s as an addition note.

And u we have bell housings aftermarket to plug and play Family 2 engines
Ya I'd love to get one in my hands, I just discovered that recently
@@t-bodyperformance770 but is possible to modify the original ones to use, 2 holes already match , some welding can solve this
@@t-bodyperformance770 and I don’t know if US Chevettes use the se gear box as us here , Here is a Clark CL 2505 D

Yes the Family II Opel head! I love that swap
I'm actually going to be outlining that swap here very soon, probably over the summer. I'm working on collecting the parts as we speak

Didn’t that wiki list the Omni as being a T body?
It's listed a LOT of bad info over the years
Omni is an L body
@@mikeallmon1
And a whole nother brand not related to GM in any way shape or form
@@Project_Low_Expectations oh, I know! I've had a T-1000 and now an 84 dodge rampage. its an L body too!
@@mikeallmon1 I had a 1980 horizon in high school, then I had an 84 Omni for parts, and now as you can tell by my avatar… I have a 1980 Chevette
