Contact Tjolley on facebook for more details

You'll need the front F23 trans mount, axles, shifter, cables, and shifter console/cup holder.

Requires you machine some martial off on the housing where it makes contact with the thermostat housing.

Awesome dude! Super happy for ya. Saw the vid yesterday and hooly **** buddy!

Minus the block of course it doesnt even seem like all too crazy of a build! Shows what you can really do without a 3 inch catback and all the cooling mods. Would it have yielded lower #s on a 3rd or 4th gear pull?
Anyway as one of the few to get 'close' to 400whp (380 here) all i can say is congrats!

I did about 7 pulls, some relatively close together

The griffin holds so much water

from 3000-8000 it only rises 15-20*; then it starts climbing quickly after that.
Hits about 136-140 by 9000+. Not bad for a stock endplate

You're a moron.

Look at the torque curve.... its flat all the way through the pull.

Doesn't peak and drop like most turbo cars. Go troll somewhere else.....

I dont think he understands what a torque curve is, he just looks at peak numbers and talks about his daddy's super fast scion

Look who the real trolls are having a fat peak number is awesome and it is funny to have all that power and still not too high over stage 2 #s torque, that really is a nice graph. And who needs torque when youre pinning...

S2 torque is like 220-225 ft-lbs at best.... You to miss the point of how well that torque curve & powerband will make that car move.

All the kiddies that just look at peak numbers miss what's really going on.

VW's are making your brain shrink. Ha.
