Ok so I have a 100% stock 06 evo mr. I am planning out the build and saving up for all the parts and labor. I'm planning on putting in a stage 2 2.3 stroker kit (not sure which brand is best), maybe 272 or 276 cams, bigger innercooler with lower and upper pipes. New turbo manifold (long tubes). 3" exausht with test pipe(don't want anything too loud so cops don't constantly pull me over) 1200cc injectors, 255 walbero pump and sd conversion. I really want to get 650whp on e85. I am unsure of the turbo I should get and if I need a new block or if the stock one can handle it, I'm also completely clueless about the transmission and diffs. Any input on my build plan would be appritiated.

 

First thing you need to do is sell it and buy a GSR, or start planning out your 5 speed swap.

Those injectors won't be big enough for 650whp on e85, nor will that fuel pump. You'll need twin 255's or a 450 and a 255 setup on a pump controller.

 

If your gonna have a shop build you a 10 second car, its probably a good idea to work with the shop and have them help you form the strategy for how you are going to get there. There is a ton of nuance that goes into building a race car that most people just don't factor in when taking on a project like this. Safety equipment and regulations probably being one of the most overlooked factors. Maybe you aren't looking to compete, but im sure you aren't looking to die in a fire either.

 

I feel like you should do a lot more research before going to a 10 second car. What does "stage 2 2.3" mean?

If you change the fuel line feed to bigger tubing, you should be able to get 600 to 650 whp on E85 with a hardwired 450 pump. You'll need at least 1650cc FIC or 1700 ID injectors for the job, and you'll need to drill the return on the fuel pump assembly with a 9/64" bit.

I would say if you've never modified a car before to go with simple bolt ons and learn more before just going full bore on a 10-second build.

 

Anything involved in drags racing should not be running a 2.3L or any 100mm crank motor.

 

Wouldn't you want to run a 2.0LR or a 2.2 for a better R/S ratio for a drag car? I was under the impression that 2.3's were generally better street motors. Of course this is just a generalisation as I realize there are a few different ways to achieve that displacement.

If I ever grenade my current 2 liter I was always interested in getting more displacement, but I wanted to keep a decent R/S ratio to keep the piston speeds down. I'm never sure what the best all around set up is. Kinda leaning towards the 2.2.

 

10 sec car and 650 hp is to different things. You can build high 10 sec car with stock 9 turbo on E85 and slicks.

 

See edit. I left out a word...lol.

 

there are many ways to get to that 10 second e.t. and the approach will greatly depend on the constraints you have going into it. If you are going to be competing in a class then you have rules to worry about. If you want to drive this thing on the streets then you have laws you need to obey etc. Also obviously the easiest way to make the car accelerate faster, handle better, and brake faster is to drop weight, but what are you willing to give up to achieve those goals? Another thing to consider is the cost of driving the car. If you build a race car, you need to maintain it like a race car.

 

You are in Cali just remember smog and state ref. The cops are ****'s out here.

max out the stock turbo first. You should be able to make 420-450whp on e85. Run that while you plan your upgrade. You might find that the stock turbo is plenty fast.

 

Or even an HTA71. THat little turbo is awesome.

And yeah on the refs. My car looks as stock-ish as it can with my engine build.
