They are “like” the 90-92 transmissions, so because of that they are stronger. But they have synchros of old transmissions, so shifting isn’t great…

Maiden voyage! Lots of small bugs to workout!

Yea… I started this project in 2001… 22 years ago! But I was determined not to be one of those guys who sit on a project for years and then just part them out without completing them ;)Yellow Durango actually came after I started this project 😂 I also owned a yellow VehiCross for a few years...

My first full custom exhaust (2.5” for quieter systems)

I have been locked out from the forum for a while, but Chris let me back in ;) Thank you.The downpipe and wastegate:

Well, it took almost six month, but got my Morrison Fabrication RWD header. I am thrilled with how it came out!Next step exhaust!

What is “GST4”? Must have been an early prototype name?And what is up with Talon wheels? 😂

I must agree with you, I am used to seeing around .600” at the slave cylinder. Perhaps that .400” number is a bit high?

I am getting 60mm and 108mm for 1.8 ratio.So if we need .400” on clutch side, we would need .720” on the slave cylinder side.

Using these numbers, I am getting the following overall ratiosDSM 8.16:1 TR7 w/.75 master. 4.95:1 <<< 😮 TR7 w/.625 master. 7.13:1No wonder I thought that current effort was ridiculous 😂5/8 master should be much softer, but still stiffer than DSM 🤷‍♂️

As I expected, DSM has much larger pedal ratio than TR7, 5.67:1 vs 4.25:1, which explains why clutch requires so much more effort.I was totally wrong about AWD DSM data (that is what I get for being lazy and getting numbers on line, instead of measuring them myself). Slave cylinder is .75”...

Thank you for the Y value!I stole that image off the net, it should be the way you measured it and not a vertical projection. But it is close enough to get the point across ;)Do you also happen to have the pedal around to get X value?

Paul, I have narrowed it down to the pedal ratio.I have Bill’s T5 bell housing with Supra slave cylinder (.81, same as DSM) and 3/4 Wilwood master cylinder (vs .81 on DSM).So I have some mechanical advantage and yet, my ACT 2600 feels much stiffer! That leaves pedal ratio ;)

Has anyone ever figured out 1G or 2G clutch pedal ratio?I am trying to figure out why ACT2600 pedal is so hard on my TR7 project.

My transmission/adaptor came from a local DSMer who was going to put 4G63 into oval track modified class tube chassis. As this often happens, he decided to abandon his project after it sat around for a few years. Sadly, I see RWD projects being part out before they are done all the time :( ...

WC T5 from 1980’s Mustang which is coupled to Bill Hincher’s bell housing. This isn't the best transmission, but I got a great deal for it and Bill's bell housing, so it will have to do for now.

After 22 years, I finally started TR7!!!

Tim, I guess I am lazy, but I ALWAYS ID transfer cases by counting the turns ;).

You can't be off by 45 degrees, I am not sure you are doing this right...

Nope! Reversing direction would be great for oil pickup, But…. It would be terrible for fuel pick up! So pick your poison 😂 I would definitely need to add a surge tank.But reversing the direction is not an option on many many tracks, because of exit design, it would not be safe to race in the...

This is SO AWESOME! Do you have any examples of T3 headers? My TR7 will be relatively low power (400-500hp), so I do not need/want T4.

This was with Kiggly HLA regulator! ;)This was a two lap race, which is unusual for spectator drags and you can see that I had enough capacity for one lap, but not for two. Looks like it too 1.5 lap to fill my head with our and reach the VC vents.

At the end of the year, I went to Hudson Speedway for some testing.The good news, Moroso oil pan is working! I didn’t run out of oil!The bad news, all that oil collecting in the head and being pushed to the right, eventually made its way to the engine VC vents, down the tubes and onto the...

Justin, plenty might think about it, but he actually did it! That is the most impressive part! ;)

I just read that it was a Smart car! That is so awesome! Do you have build thread?

You are closer than you know! ;)My old friend Gus Mahon, was a pioneer of FWD Turbo Dodges! He had the original fast minivan, back in the mid 90’s! He ran 13.3 in his minivan, long before it was considered possible! It was his van that gave me an idea to build an AWD Mitsubishi version...

I have been to many shootouts, starting with 1996, I only misses 3-4 years and that included last two years. But this year was especially special because after breaking my back in 2019, I wasn’t sure I will be able to attend again…But I made it, brought my recently painted Summit, was able to...

Mitsubishi had THE right formula back in 80’s and 90’s: turbo 4 cylinder and AWD! Now just about everyone is using this format, EXEPT for Mitsubishi….I really hope they get their act together!

Bad or poorly bled hydraulics will show up as very low clutch engagement and/or grinding gears.But a badly adjusted clutch can cause clutch to slip. It will also engage unusually high. Can you collapse your slave cylinder if you push on it with your thumb?

I can't believe that it was almost 10 years since I did upgrade. Unfortunately, I sold my Spyder in fall of 2019, but these brakes performed flawlessly during that time! I put them through numerous Autox events! I tend to do left foot braking, to keep the boost in the corner, so that is VERY...

Man, this sucks :( . Is it me or it is almost always donuts/burnouts that ruin car events?At Epping NH IFO (where they had record attendance at IFO event), they must have had 5-6 police officers. I am surprised track owner got involved...But this even usually has extensive 2-step...

Good to see people are still sticking with this turbo! Is this Colt still with FWD?

This is an awesome thread! I am trying to combine DSM/Mitsubishi alternator logic to my 1980 Triumph TR7 wiring, which actually looks VERY similar! TR7 also uses 3 wire alternator, with S line going back to the battery, WITHOUT a fuse in the system! I think I am going add 30AMP fuse to it...

This is the Build Thread for 4G63 Powered Triumph TR7. Reply below.

Bill Hitcher is an amazing resource for RWD 4G63 solutions! He makes a custom bell housing to adapt 4G63 to at least 5-6 different popular RWD transmissions.However, that excludes Nissan and Mitsubishi transmissions, which use integrated bellhousings :(. I know he was considering making an...

Did you ever find another source?

Which calipers dod you have? Do you have photos?

And those are 16x8.5!!! Too bad there are vertically no 245/45/16 tires left :(.I might reach out to Todd about those cast calipers.

Chris, I got 2G hose to work. But I didn’t like how close it got to rubbing on the axle with wheels turned all the way.However, they look awesomeI know that three calipers had a problem with flexing because power brake system created too much pressure. Do you recall what calipers they...

Stubbie that goes into the diff (and break) is also larger. So you also need to upgrade the diff.But parts are you currently using?

GRNDSM updated THE Ultimate SleeperView updates to this DSM profile...

Some new developments for the Summit, I painted it Blue By You color and took it back to the track! It ran personal best: 11.57@123!
