Questions..:

Suggestions feel free, smart azz comments keep to urself

1. I need a sufficient sized turbo to attain 550whp, looking at t70, gt40, gt35r/gt40 wheel

2. Who makes cams for our cars

3. are adjustable cam gears worthwile for stock cams?

1: A gt35r would be perfect for your hp goals...

2: toda, hks, trd, schnieder...

3: no... from what I've read, heard, talked about, adjustable cams arent worth the money... BUT, the main reason people have suggested I shy away from them is because Im going with an AEM, so my timing will be controlled by that...

For 1 and 2, talk to Sean at Titan...

Does boost come in slower on an automatic opposed to a stick?

Does boost come in slower on an automatic opposed to a stick?

Not with a 3000 + rpm stall :naughty:

An auto will keep the boost at peak as well...you won't lose rpm due to the shift. You can't out shift an auto...course driving ability helps a huge amount with a manual too. The 340E has to be built to take the higher HP numbers...it's expensive (in the $2500 range), so most guys go the manual route.

if the gt3540r is too expensive for ya try a nice pt67 or t70.

 

[trufanatic]

whats the perfect or close to perfect intake and exhaust AR's for my 500-600hp application.

 

[Justin727]

.68 or .81.. i personally went with the .68

 

[Reign_Maker]

Depends on the turbo you go with... You go with a GT series turbo, the wheels are different, more efficient, and cost more, but you can use a larger AR on the exhaust side and maintain a similar power curve... So if you go with a GT, get an 81, if not, then something smaller than a 70...

I've made my list and im now checking it twice, alot of this crap is STILL in the mail.

Any suggestions for my bottom end from my list above i think im pretty much done there or am I????

For fuel, im doubling up with an intank Walbro 255 and an external 255 also.

 

[Justin727]
