Hey all, back again for some advice from the wizards of shoptalk. Lots of changes in store for the upcoming season. Theres a couple major things id like to get done but im not sure what should take priority. :?:

With the plans of stepping everything up i know the transmission is gonna need to be looked at, currently is is completely unknown but i can guess its a dual side cover IRS from a beetle w/ a 3.88? Never checked the fluid and ran it all fall driving it like a pissed off teenager :mrgreen: all shifts are smooth and the seams started to leak at the end of the year, I definitley need to build a whole motor and transmission cradle because its on stock arms and i believe the irs housing is cracked on the lower motor housing bolts. Ive been looking at a bunch of options for the driveline but i think the cheapest and most efficient would be to trade in my core for a built rancho or similar setup. Other ideas were a porsche 901/911 5 speed or a bus transmission, or getting an old housing ang building my own?
What would you all suggest for the bug(1500lbs) street and strip use, i want something i can beat the dog snot out of and still have a decent time driving on the street; also i heard long gears are good on a turbo car. what do the drag people usually run? im still a bit unsure about transmission stuff but id love to learn more!
Another thing im looking at is to replace my General xp2000 set to something a little lighter and road worthy :twisted: Im really not sure how they made it through tech: (image)
Looking at a street radial like . MT or similar but would also be comfortable with a performance street tire and not just an all out drag wheel. the current rear wheels are 275/50r15 and i'd like to retain the look of the big back tires and smaller up front, if theres a similar set to the General xp2000 i would also be interested in something like that.

Manifold! Im planning on building a new exhaust manifold properly this winter and im pretty excited for that. 1.5" primaries and 44mm wastegate, Think we're going to get a t3 collector flange and build our runners up to that, but we have a couple ideas and im sure we wont decide until the materials are in front of us. Have any of you turbo guys tried building a header that merge the two cylinders off each head together before they go to the turbo collector or should i stick to the 4-1 collector right at the turbo?

Speaking of turbo, im planning on getting a new snail but i've been very indecisive. Looking at staying with the t3 family and using the same .36ar housing on exhaust but on a 50 trim or a super 60. I want to splurge on a ball bearing and a fancy billet wheel but theres still a lot of tweaking and learning before im ready to step up to an investment like that on a little project like this. Im also willing to switch completely over to a k04 or something like that or a tiny borg warner twinscroll. Ive spent quite a lot of time putting in combinations on RB racing calculator. looks like its gonna want to flow 20lbs/min for the power I'd like @12psi. Which leaves room for me to grow to hopefully 15-20 psi with the cooling power or methanol...

Methanol setup is inbound for the build as well hopefully by the end of the 2018 season, Ive picked up a couple things to build my own system, probably get a jet from devils own and make some ghetto system, but being how important it is i would like to use some components from a legit system, the pump and maybe a progressive controller if i can find something used and cheap. Using this and the BTM timing retard i think i can make some pretty good numbers on this old lawn mower engine.

What else do you guys recommend I should do for the buggy to get ready? Im definitley doing a couple safety measures also, Disc brakes up front (with a portioning valve for line lock and tire smoke :twisted: ) The windshield and roof is getting lifted 3" and better seat mounts are in store. I have a whole list of other little things that need to get done and i feel like im building a whole other car again! Distributors, fuel filters, carb jetting, exhaust flanges, suspension bushings, and axel seals, along with 30 other maintenance items. Oh yeah, and put a break away in the javelin-like steering shaft! :wink:

Well were starting to get into spring here and were all running about prepping for the season. Parts have been rolling in and glad to announce all the turbo problems have been solved :mrgreen: Send it out the G-Pop shop and had it rebuilt and assembled with a .42 garrett compressor housing and proper wheels fitted in the exhaust. Bolted up the turbo and couldn't resist going out in the 40 degree weather to see if spool problems were resolved. Its perfect, had to rejet the dellorto substantially and still need to dial in the new Turbonetics boost controller. Wastegate spring is at 3psi, waiting for the sun to peek out to do some higher boost pulls. still looking for a methanol setup to adapt to the intake to hit even higher pressures later this season. Here some pics from the first day out this year, nothing changed except turbo and an oil thermostat (actually still having trouble warming up, engine is cold!)

also have a bunch more parts piling up, waiting for weather to break to be able to bring it to the shop and put in a serious week of fab/suspension work. wanted to do disc brakes this year and found an old set of drop spindles (CB performance) with kingpins installed, recently cleaned and painted those and pieced together the rest of the brake components. Along with disc brakes and the "lowered shocks" it will be getting new tie rods and a steering damper put in for stability with all the new power. Also need to find something to put in steering shaft to act as break-a-way.

Other things id like to get done at the shop is re-work all engine and transmission mounts and make something a lot beefier to hold the motor down. theres hardly anything in right now to keep it in except one of those hoop conversion plates and the tabs at the end of the horns. Also throttle cable routing and some new bracketry is required on the carb, mainly miscellaneous drivability things.

A few other goodies this year are a boss 300w motorcycle stereo with bullet speakers, an old MSD two-step controller to play around with, and a 25psi VDO gauge with vacuum now! I planned to keep this updated throughout the summer if this forum is still active/ people show interest.
