Eagle was just blowing out their stock of long-rod 420A stuff on eBay - they certainly are different than stock and will require custom pistons to work properly. If you’re going through the trouble of building an engine with forged rods, spend...
I just checked CAPS for Evo 123 intermediate shaft info, here's what I found:Evo 1 RS: MD742768
Evo 1 GSR: MD738952, superseded to MD748830Evo 2 RS: MD742768
Evo 2 GSR: MD738952, superseded to MD748830Evo 3 RS: MD748831
Evo 3 GSR: MD748830...
Good question on the Evo 2/3 input shaft, the tooth counts seem to be the same as the DSM between 1st and 2nd (heck, 2nd gear is the same ratio). The Evo 1 (with its 2.571 1st gear) has a 14/36 tooth arrangement, so it's different. I'd defer to...
Check out jafromobile's channel on YouTube. It's almost entirely 4G63-centric how-to videos on building engines, and this is something that gets covered (among a hundred of other incredibly valuable videos).
I like King Bearings, they're incredibly consistent. There were some reported issues with ACL a few years back that I just couldn't ignore, but I'm sure they're just fine for you. The only issue is whether the King MB5209XP main bearing is...
Received hub/sliders. They're so shiny I don't want to put them in a box where I can't see them. Measurements taken with my no name brand cheap verniers. They matched the matched an old factory set I compared them to within 0.2mm or less.
1/2 pics.
It was just dirty, it’s not thaaat bad. Here are updated photos, it looks awfully close to the ring. This head absolutely needs to be saved though, Curt Brown isn’t around to make another.
I saw some super old information saying a RR car had an Albins dogbox that floated around a bit. The Albins kit was either a 5 or 6 speed helical dogbox at the time with super close ratios, but I heard of a custom made rally kit that even Albins...
I just unpacked a CBR head and found these flaws in the deck. I’m not sure how this damage could have happened (likely on the bench?), but I’m not sure the best way to deal with it. The head will obviously need a mill to correct the deck, but...
It may be counter-intuitive, but it’s cheaper to buy the best example possible than to buy a mediocre example and restore it back to garage queen level. Kicking myself for not buying a mint Evo 1 years ago for $10,000 in Japan, when a paint job...
My downpipe isn’t friendly to stock OFHs, and I wanted to keep the provision for the air/air oil cooler and add the temp sensor port. Evo VIII/IX was the only solution that would have worked. The filter and ports for the oil cooler lines...
I sent him a pan and three pickup tubes a year ago and was in a bad spot with my build, so I let it sit. Lately I asked him to build it for use with an Evo IX oil filter housing - it looks really tricky to do but he said he’ll find a way to do...
Just an FYI. Racefab is still doing these. I just ordered a new pan and pickup and will be sending them to Rob for modifications. The price did go up a bit though.
Holinger did a run of 6 speeds for Ralliart’s Group A cars in the 90s, which was the only pure sequential W5M33-platform transmission. It used a GTO transfer case and could be adapted to a variety of final drive ratios. There were other suppliers...
FYI - a sequential has been released. I haven’t looked to see if it’s the same group, but they’re based in Central Europe and the overall design looks to be the same.
Congratulations to the crew at Boostin Performance for breaking down the 6.99 barrier in the new Red Demon, the first AWD 4-cylinder car to do so. Amazing persistence, determination and talent from the team to make it happen! Well done!
Yup. A CARB certification costs $10,000+ to conduct, they would be lucky to get $10,000 in sales from the 420A crowd. And it's unlikely that a full turbo kit would end up passing CARB without costing an absolute fortune to tune it properly.
Boostin’ Performance is probably the best head builder that fits your description, and Magnus is likely a good candidate, as well. I sure miss Curt Brown..
