I'm thinking an 05 for body style (just preference), 04 gear shifter (lighter feel), 07 tranny / diffs (superior gears), VF-48 turbo (I think they fit?), stage 2, water meth, aggressive protune and a FMIC? Just until it blows up...
..and the real motor goes in

 

Only thing I disagree with is the VF-48. They make more midrange torque than the 39/43 when at stage 2+, but have inferior top end. The 07 gears will only exaggerate this. Need proof? The 08-09 STI has a lower redline than the 04-07 STI. Just a thought.

Maybe just a ported/polished 43? If you want to have a stock turbo STI...

 

id say go with an EWG instead of spending money on meth. Like ugm said, get it ported/polished. Definitely helps. I also don't see why you need an "aggressive" protune. You will only be making like 5-10whp more than a safe tune and you will be running a much higher risk of blowing it up. Like in my car I had about 15whp on the table but snowman knew what I was using the car for and made sure that it ran 100% without blowing anything up. Car had 30k HARD DRIVEN miles on the engine and it never skipped a beat or burned a drop of oil.

....until the fire burned through the external oil cooler hose, then it burned a lot of oil

 

horrible.... why would you say vf series and perfect in the same sentence

 

I dont know about a VF turbo, unless it were twin scroll. I'd rather run a 44lb/min turbo for an around the town monster.

 

This.....

I would go the meth route if your not afraid of the consequences. Spraying 100% meth would be almost like running c16 every time you got on it.

Can you say a lot of timing, and stupid boost. Trick is finding a tuner that's meth savvy and knows how to really manipulate the timing/fuel map accordingly.

(I've seen a lot of tunes with standard timing when meth is at full volume, and rich afrs as it were on pump)

 

its all about adding secondary injectors and spraying e100 when you get into boost

 

the VF series has superior spool, Andrew I think you're right about the 48...

I will most definitely be going with a much larger turbo and setup for the built motor, but I kinda want to run a stock ej25/vf series until it explodes... I dunno, maybe I'll do a G series on that stock block

secondary injectors is an interesting idea for the real motor.........

 

so youre actually gonna go waste money and throw an 07 tranny in an 05? for some reason im gonna call bs because thats just retarded for a few more mph on a few gears and if you have a good tune you can run a 35r on a stock block.... just be careful with picking that person... unlike what i did

 

aggressive tune for the win because if your gonna build why not go full on and its not all about the extra 5 to 10 whp it also has to do with the better response, aggressiveness of the motor, better powerband, there are too many things to be gained with an aggressive tune over a conservative tune. and lol to blacksti on the vf comment lol so true though...
