Ef2 will make your goal, ef3 will put you into the 500s with proper mods easily.

 

sent u a pm btw your power numbers what type of dyno will you be tuning on mustang numbers are diffrent then dyno jet numbers

 

You don't need a built motor for 450 hp wtf you been smokeing. A good tuner who knows what the hell he is doing will make that easily on a red or an ef series turbo with no issues on a stock block and it be safe.

 

If you want those kinda #'s pm me I will guide you in the right direction and where to get it tuned. Built motors, trannys etc aren't necessary in the least. Reguardless of you turbo selection you let me know when your serious I'll set you straight.

 

so is it safe to have EF4 with the stock block?
i will send you a PM

 

yea just keep tq down

 

crusedsm is running a map ef4

 

I have seen this done exactly twice with the Evolution X. One took 2 years to explode with a JB FP Black (the guy was easily the best driver I know, period). The other took just over 12 months with a JB FP Red (again, really good driver). Sure, it can be done. However, they all eventually go. A lot of it isn't the tuner. A great deal of it is just knowing when to let off, take it easy, do this, do that, etc. By your standards, a "good tuner" would just play it ultra safe with the timing and baby the hell out of the torque. What is the fun in that?

Do it right. Build the motor. Get a new clutch and CMC (those should be the first two mods done on ANY X GSR). Get the supporting mods straightened out, and then let your tuner give it hell. Why worry? You can browse for hours on end around in the technical forums and read countless threads about blown motors (mostly, it is the rods going completely). It can happen, some at lower power levels than others. I would not recommend to anyone else to push for 450 without at least dropping in a new set of pistons and rods. Again, why worry about it?

 

That is all an opinion, by the way.

 

I realize the x is a totally different monster then the 8 and 9. But the the thing is Tom knows how to tune. He knows whats safe and whats not. I don't want to see a guy take it somewhere and have the thing go up in flames like I have seen alot of times. I mean people I know want to make the car safe, reliable yadda yadda but I do know that the x motor is a bit more efficent then the 8 and 9. With this said it should be easier to make that goal and make it reliable if the proper steps are taken. I by no means have any ill will or anything twards anyone for making suggestions, but at the same time I don't want the guy to spend a **** ton of cash when it can be avoided. 450 whp isn't really a ton of power for these motors at all. Tq wise I am sure it may be a little less then what I have in my 8, but I will say Tom knows how to keep it together, and make it fun.

I do run an ef4 on a completely stock 2 liter. My valve train is the only thing that is upgraded along with cams on my head, and my car will make a ton more power, but the thing is I want it to be reliable enough to hold together till I want to build it. Fuel as I think I had said before or maybe it was someone else I forget will play a good roll in this. Reguardless I trust the way I have built my evo and I trust my turner to make it safe and so far no regrets.

 

It can be yes. There are plenty of guys who make higher hp #'s on there cars with really good results but as I said it all goes back to the tuner. I can get away with the #'s I have being I do run e85, and keeping my tq down and make it spool a little later in the rpm band. I have good transition throughout my rpm band and some people say it is a little laggy, but for what it is making the kinda power I am and feel comfortable to beat on it and not worry is a pretty good feeling. Now with the x it is a bit different. I can help but it is a new monster. Chris Carey from map may be able to answer that question a bit better. I can help with upgrade advice and what nots, but he I'm sure can help with turbo tech questions. The ef2 is a really nice turbo. I rode in a car that was a 9 and it was damn nice. Good spool made nice power and was alot of fun to be in. Getsideways runs and ef3 and he loves it. Again totally different animals. Tscompusa probabily help you with your tuning questions and goals and he is pretty good at helping out with your setup and how to get you there. Hope this helps some.

 

just in case anyone is looking for a map ef4 turbo im selling mine it has less than 1500 miles on it. its ported and heat coated its like new still, only drive car 30-50 miles a week send me a pm if intrested. upgraded to a ets kit 6266 bb

 

I will quote you a second time being I missed it origionally. Reguardless of what engine being the 4b11 or the 4g63 the stock rods are tiny. A good tuner who understands this is a stock motor will keep the tq down as you said and stretch the powerband slightly to keep it in tact. What is the fun of that you asked? Drive a car with upper 550's hp even with only 438ft lbs of tq and I beat on my car all the time and it is fun. With eboost and say an ef2 you can still have a pretty fat powerband being the ef2 will not flow as much and or make as much power as an ef4 which will make the car a bit more exciteing to drive. I hope some of the x guys who run eboost on stock blocks will chime in and give some examples of how there cars are on turbos close to this. The whole point if stretching out the tq and makeing the powerband a little less then all out is to keep the motor alive. I agree about doing things right, but if its something that can be avoided for only 450 whp and if he doesn't want to go above that or anything I don't see the point.

 

I'll bump you for a good turbo.

 

I am happy with my tuner, as well. Although some have bad things to say, I would put Jestr up against anyone. If you want a safe tune, he can do that. I told him to give my car hell, and he made some sick power. I am just afraid that the OP might need a little wiggle-room. If he were to try and drive my car, it would explode. No question about it. It is a ***** to drive, which is why I have so much fun with it.
