Howdy,

I currently have the akuma intakes and intercooler pipes as well as a turboback catless exhaust and a cobb accessport dyno tune. The car is SST transmission. It is a daily driven car but it is raced plenty.

It ran a 12.9 @ 106mph on the track. I know it can do better in better weather but for now, the high 12's are still not where I want to be.

I have an SST transmission so I know I can't just slap a big turbo, run some E85, and call it a day. I need to keep the torque low so that the trans survives, unfortunately.

What do you guys think I should do next? I had some ideas but I'm still an Evo noob and I really don't know what would work best.

1 idea was to get a larger turbo, something like an FP Red, and have it tuned so that the torque is the same as I currently have or maybe even a bit less but to have the power come on later in the RPM band so my trans is ok but I still have nice top end power.

I also have access to E85. I'm not sure if I should just convert to E85 and keep the stock turbo and get extra power of if the E85 will not be worth it because I can't turn the torque up on the stock turbo without blowing the trans.

Maybe Meth?

I want to keep the tranny and motor stock because of costs.

Thank you so much evo brothers!

 

The old saying, how fast you wanna go? How much money you got? Here are two routes to consider...

Example 1 - Stock turbo on E85

Example 2 - FP Green on E85

Why not run a black at low boost keeps the tq down and has good top end grunt. I'd still run e85 if was possible i mean why not easy hp for just fuel.

 

Yeah I was recently thinking of using a black since the spool will be slow and maybe that will keep the transmission happy. Top end should be great and yes, maybe E85 would be good, even if I get the tune to be super conservative so that the #'s are similiar to 93 octane.

 

In regards to Example 1, I don't think the trans will hold with that power.
Example 2: that is an awesome build but I know it costs around 15-20k and I do not want to spend close to that amount.

Money? I want this to be a budget build. I was hoping to just basically slap on a turbo, keep the torque low, and gain some more power. I have access to E85 so I can use that no problems if this will work better with a turbo upgrade. How fast do I want to go?
Maybe 11.99 while being safe as a daily driven car? is that possible with stock trans and low torque? Of course money = speed and reliability, so I don't want to compromise reliability. Will compromise speed...

 

Bbx lite or bbx full would be my choices.

 

If your seriously on a budget i highly suggest just switching your fuel to e85 and see what type of gains that gets you. That's the cheapest you can do.

For 15-20k I'd just go buy the ams 2.2 fully done motor and drop in. Plus for that cash it better run 500+

 

What do you mean? It's holding that power already and if I remember correctly the car already has 30k on it.

My car has the Cobb 400s kit with the FP Green on 93 pump. It’s at 376 whp 361 ft-lb on the Cobb Mustang in Plano. I'm not going to vouch for reliability yet, since the car only has 2000 miles on it, but I can tell you this: for a street car I don't know how you can live with a bigger turbo like a Red or Black. It won't be an enjoyable every-day car with all that lag and lack of torque low down.

 

BBXL, injectors, a good pump gas tune.

 

I can't imagine having a daily driver with any more lag than stock really. For drag racing, a black or bigger is just fine, but if you have to live with it daily a green is as big as I'd go. You can make 11's on a green I would think... You're running 12.9 at probably 300 WHP, 11.9 should be doable at 400ish.

 

Don't you have the SSP clutches and all? I'd like to keep my transmission stock because I don't have $5-8k to spend on the trans, you know? If your trans is bone stock inlcuding clutches then I have to relook at this and maybe copy your build!

Thanks for the suggestion. I am new to the evo world so I will look up this turbo setup!
Same as above
This is something I did not really think about. The reason I kept thinking of a larger turbo with lag was so that the SST transmission will survive from the low torque but maybe this is not necessary huh? 11.9x is my goal with spending the least amount possible and keeping it a daily driver. All I hear about is the Red or Black but that's probably because they put up the best dyno numbers and drag numbers so that's why but you may be totally right since I'm not crazy about the stock turbo's lag at all.

 

If you think you care about lag, just do the stock turbo on E85.

One of my favorite setups so far was my stock turbo on E85. 400whp/400wtq and reliable and easy to drive.

However, I always find it funny people that think any stock frame is laggy. I have had the red and the black and rode in other stock frame cars. On the street they always feel roughly the same. All this talk about "down low torque" lost, well guess what you spool once, thats it. Downshift it if you need to or simply adjust your shift points. My FPred was seriously easy to drive every day, the black was getting a little closer to t3 type lag but still, I adjusted my shift points and it was fine.

Now with a 2.2L I am keeping a big stock frame but I am guessing it will drive almost like stock.

If you think you care about an FPreds lag, just drive one for longer than 30 seconds and get used to how you drive it...its easy.

 

My car still has the stock SST, but like I said, only 2k miles. Really the biggest bang for the buck is E85, like example 1 in my first post. Keep in mind even on a manual trans sooner or later you wil need a clutch if you often use the car hard. With the SSP packages, you can replace the clutches for about $4K, labor and parts included.

 

I don't want it to be disgusting where I hit the gas and I can't move but like you say, maybe if I just keep it in the powerband it won't be so bad. The transmission downshifts very quick so as long as it spools upon downshift maybe you are right and the Red is more of the way to go for me?

This is true. Eventually the clutches will need to be replaced so that is a good point.

I think at this point I have narrowed it down to keeping stock clutches and trans, stock motor internals but swapping to bigger injectors and pumps and going with E85 and also slapping on either a BBX, FP Green, or FP Red.

I will look over the dyno graphs, performance numbers, and prices of the 3 different turbos and figure it out from there.

My heart tells me to go for the red so I have the most power. My head tells me go for green or even stay with stock turbo and save some money and have quicker spool.

 

i would try the e85 and see if you like then from that point you can look at getting a bigger turbo btw i did a bbx light on a mr with full bolt ons and it was not worth the money or time car made 25 -30 whp tops more
