New Build advice (be gentle ;-)

Changing 3&4 is less expensive than 1&2. Otherwise, you won't feel much difference between the two. Necessary strength would depend on how much power you intend to push and how easy with the clutch you are.

You might find this thread interesting. This was my journey. I'n hindsight, the only advice that I wish I wouldn't have ignored was the short throw shifter. That's going in next winter.https://www.speedsterowners.com/forum/readmsg.asp?t=17759

Tom - Great link. It sounds as though you did very well for yourself. I

I'm building my car from the ground up. If your building from the ground up then consider the Porsche 901 5-speed transmission. It does involve a bit of fabricating but its not that difficult. I think Intermecanna use them with a 2110 engine. Tires - I spent a long time earlier this year looking at everytype of tire out there. Ended up with the Falken 912 as the Bridgestone 960's which are better have been discontinued for a couple of years (I think there are one or two places with old stock of the 185/65/15), Ebay had some new ones on line. I have 185/65/15 on 5.5" rims the front, 215/50/15 on 7" rims on the rear. The profile is slightly lower on the rear, hardly noticeable. The amount the tires sticks out from the rim is equal front and back (the tire size is well suited to the rim size, it dosent protrude out).

Option 1: Your Ring-n-Pinion is 350.00 and 400.00 for the 3rd and 4th. Gear

Option 2: That mainshaft is 750.00 so the price is the same.

I

David-

I too prefer Option 1. The steps between gears are just a little more evenly spaced. I have heard a lot of grumbling about the cost of replacing the mainshaft, first, and second gears, but I

Get a 901 5 Speed box. I had a 4 speed 901 box that I just rebuilt into a 5 speed. The shifting is amazing and I am really excited to see how the 5 speed works. Next xmas I want to get one of these

If you throw 914 gears in the box they are only about $35 each.

Mat,

Email me when you get a chance - I ended up buying Wolfgang's 914 5-speed and he said you have a part or two I will need for my speedie.

Thanks

Mat,


Howard Borlow and I have this Wevo Shifter on our 915's and they are great.

Marty, your 5 speed shifter looks neat...but your drivers seat looks uncomfortable!!

I know the wevo is awesome as well. I keep hoping I find a deal on either one but it has not happened yet and it sounds like once you go wevo you never go back.

I am going to start another post asking for reviews instead of hijacking this one.

that seat is perfect if u have hemmers.

Don

yep I do. I didn't know I had a 'P*ssy Point though. I went 2007 stroker as well so I guess our PP's might be similar

Actually Luke the main reason is that the 914 gearsets A,N,V,ZD go for about 30 bucks each while the 911 gearsets fetch a pretty penny. It was my cheapness that had me settle on those gears. If I hate it I will switch it up.

Mat-

By the way- I have been witness to the (natural) birth of both of my children and I can say without equivocation that my wife has a P.P. far greater than I will ever have. I am in awe of her fortitude.

Luke you can't stop. Power breeds power. You can't deny that. It's human nature. Case in point my next build is already in the works..and is going to be a solid 200 ponies and will have a top speed of 150..limited...and get close to 40 mpg..(that's right I said it 40 mpg)

.and who am I to say anyone is fulla' bs. I thought PP was refering to something else altogether...sic..

All I know is I ordered a 2007 from Chico and he said it was going to be a torque monster. I used to know all the specifics..but alas too many drugs at an early age have limited my memory banks.

I could access that imformation with a simple phone call/email/text but I promised Chico I would not under any circumstances 'bug' him during the build. I paid cash outright for the combo to speed the up process so i'm not going to rock the boat now.

My gearbox is a lowly type 1 on with a 3.89 gear..and a .82 4th..supposedly bulletproof according to the man'. Once again the specifics have faded away...

Back on topic. I would consider a GENE BERG 5 speed but stay away from a 3.44 (they are around no matter what folks say). Go with a 3.89 and make sure all your gears are evenly spaced..with the exception of 5th for croooozing..OR go with the 3.44 and get evenly spaced gears in all 5. Hopefully that 2007 will pull that 5th to your satisfaction

OR if dinero is not a limiting factor go with the above mentioned boxes from Porsche. More work..but great stuff and resale is alot better

OR better yet go turnkey and call someone like THUNDER Ranch..or Beck and get a real nice car with a steel tube frame. Skip the headaches and have them design the car of your dreams. Paint it red and call it Bloody Mary....lootenant'

PS. Lucky for me my kind was never meant to breed so I'll never have to witness that miracle. Your braver than I'll ever be

O.K. For the sake of clarity and decorum, I will henceforth refer to the moment when fear and self preservation take over as the

just to clarify the next build is a mid engine subie based car..subie gearbox..BIG subie' discs designed for 3200 lb car. I won't be going much past 100 if at all but I'll be gettin' there rapidly.

AND yes I've got all kinds of free time. I'm a free time millionaire so to speak..well except for running the landscape deal.

Basically I go out early to a few jobs, do estimates/billing/payroll...then come home mid day (to no kids/spouse/dog) and f'off working on my latest garage queen. That's it..no kids, no mortage, no outstanding credit, no picket fence of any color...nada. Just me and the cars.

Funny thing about cars they don't complain, need braces, watch too much tele'..

Hopefully the house is full of girls.

Moose - you've earned that big gold star that's right smack in the middle of your Man Card!! NICE!

Mat-
you're cute. If the house were full of GIRLS our man wouldn't have all of that wonderful free time, now would he? No, he wouldn't. He would have CHILDREN, like the rest of us wonderfully blessed slobs.

Keep on rockin' in the free world! (If that's your idea of a good time...)

What Jim said X2^2 (that

Back On Topic:

Type 1. 90.5 mm bore x 78 mm stroke = 2007 cc

Damn right Jim. Man Club forever. It's a bad habit I can't break

Oh yeah I just got an email from Burt Reynolds..says your doin a good job keepin up the MAN Club tradition... even though you don't drink Miller Lite.

Actually no woman can tolerate my auto hobbies and my f' it "I'm goin to races this weekend you comin'?" attitude. The Porsche is an attempt to persuade some of them to ride along

Mat I wish the house was full of girls. However adjacent LAKE TAHOE is... and my other passion is wake surfing. That's a relatively new sport and everyone I take out on the boat can't get enough. That's where the girls are. Every summer I teach plenty of them to surf. Drop by and I'll take ya'all out. We fish too. Trout..Mackinaw and Big Brownies

Sorry Nord' carry on...

Dude, screw the 90.5s, that is old school. Put in 94mm Mahles and call it a day. 78 stroke is the same as mine, then it will be a 2165. 44 IDF, 42 x 37.5 valves, Webcam 86B, 1.5:1 rockers, 9.8:1 compression. Bulletproof, 6500 limit. Torque curve flat as a pancake, she LOVES to rev, but you don't have to. I'll show you at Carlisle. Oh yeah, and my gearing is 3.44 final and stock gears.

Humphrey Bogart was, among other things, an avid sailor. He once said,

love that quote..and i agree with 94mm

Yes, Luke, cooling on the 94mm cylinders is a non-issue. The 92s were the problem. Anyway, if you're paying machining cost for the smaller ones, it's the same price for the larger ones anyway.

Talk to you next week, over a beer. Love that Bogie quote!

Oops, my valves are 44 X 37, my bad!

Build what Daniel suggested; I would keep the compression a bit lower (9 1/4- 9 1/2); then you won't have to be so spot on with the tune all the time and a bit of bad gas won't be such a problem. And the power you give up will be negligible. The original 92's had thinner cylinder walls and were prone to warping if overheated; the 94's are thicker and almost as thick as the 90.5's. Go for the 94's- displacement is everything!!

When I moved from New Orleans to Brooklyn, I sold off my firearms. Within the 5 boroughs handguns are verboten, and I thought I better not risk it. As an aside: If you were to spend some time in both cities you might conclude that one is quite easy-going and friendly, while the other can be downright rude. That

I know nothing about guns (except they go boom and don't be in front of one when it does; I'm Canadian, eh) but I do know a little about motors. BIGGER IS BETTER!!! You can get 130hp out of a 1600 and 130hp out of a 2 liter. Guess which one is easier to drive and take care of??

Allen - like the illustrious Angela once said "Aerodynamics is for those without enough horsepower'!

Alan-

It sounds as though you know just about all you need to know about guns. They are machines, tools, just like any other, that ideally no one would ever need to use. Personally I try not to be anywhere (not in front, behind, beside, I mean nowhere) near one when it goes boom, except under very tightly controlled conditions. But since America is the most heavily armed nation in the world, with 90 guns for every 100 citizens (Reuters, 2007), their ubiquity can make them unavoidable, especially South of the Mason-Dixon.

I understand and agree with the notion that the easiest way to produce more power is with a larger motor. If we accept that as true, it would follow that the easiest way to produce a specific amount of power would be with a properly sized motor. So, before we can answer

I stayed at a Holiday Inn Express last night, and I still don't understand this thread...
