I ordered two Option Racing 60mm BBTBs from SeoulfulRacing about a week ago.

One is for my wifes 2000 Tiburon with an automatic transmission and CAI, 4-2-1 header, 2.5-inch high flow catalytic converter, 2.25-inch mandrel bent exhaust, 2.25-inch Flowmaster muffler, Air Ram, phenolic spacers, NGK premium wires, NGK iridium plugs, underdrive lightweight crank pulley, lightweight, water pump & power steering pulleys, 5w30 synthetic oil, and weight reduction. This car also has lighweight 16-inch wheels (16 lbs. Motegi FF6) with 205/45ZR-16 Toyo Proxes 4 tires.

The second is for my 2000 Tiburon 5-speed with CAI, 4-2-1 header, test pipe, mandrel bent exhaust,, Air Ram, phenolic spacers, lightweight flywheel, MSD super conductor wires, NGK iridium plugs, underdrive lightweight crank pulley, lightweight, water pump & power steering pulleys, 5w30 synthetic oil, synthetic transmission lube, and weight reduction. This car has Motegi Trak_Lite 14 lbs. forged 17-inch wheels. I am undecided on whether to go 205/40ZR-17 or 215/40ZR-17's.

This car will be daily driven and I prefer not lose any bottom end if at all possible. Difficult task when trying to gain HP, I know. The car will see the track on occasion.

My question is this: Should I have ordered the 65mm BBTB for my 5-speed car?

 

I think you should have, but how many more modifications do you plan on doing? For right now it would be fine with a 60mm, but if you plan on doing some aggressive cams or headwork, you may want to swap out for the 65mm. ESPECIALLY if you want to do a turbo setup.

But you should be okay with the 60mm anyway. It's unlikely even with big cams and headwork that you would see a big gain with an extra 5mm.

 

Post some pics and reviews of those TB's.

 

When they get here I will.
I just ordered them (along with my clear corners for the silver RD2) about a week ago. I spent alot of money ordering all of the upgrades in my signature for my Tibby to make it above and beyond my wifes Tibby. When I ordered the VIS carbon fiber hood I got a better deal for two, so I ordered an extra for my wifes car. Ditto on the Goodridge stainless steel braided hoses from NOPI. I got two sets shipped for $163.50. The BBTB's was the last thing my wifes Tibby needed so I figured if she was getting one, so was I. wink1.gif
Anyways the items are just now starting to trickle in, so I'll keep everyone posted...

 

i think the 60mm TBs will be fine.. unless you do some aggressive head work and valve train work, you wouldn't seem much of a difference. when i was N/A and i put my air ram and my 61mm TB on it was amazing..

i went back to the stock TB to see the difference and it was such crap compared to the 61mm tb.

i think you should buy one 65mm also, and see which one you like better, and if the 60mm is better, just give me the 65mm.

 

I would like to do some headwork, but it is hard for me to trust anyone with my engines. It's have to be someone with a flowbench, and I am not sure I want to spend that much money on this car. We'll see what happens...


I will probably end up getting the 65mm also and see which one performs better, then sell the 'leftover' one. This will not be for some time though.

I am moving from Michigan to Arizona sometime around the end of May so I am not going to be spending much more money on the cars until after I get settled in down there.

 

Youll be fine with the 60, and if you ever get more extreme N/A mods or boost you can easily sell the 60 and buy the 65

 

Moving down here? Congrats man, we'll have to meet up.

Option Racing?

 

lol, good catch!

System Upgrade is what they are. I have no idea what I was thinking.

As for meeting up, I am pretty sure that there will be a Hyundai meet, big race, or import show / classic car show / Mopar show where I'll be out your way.
