aiming for 400+ whp

[MKIII TURBO60-1]

ok, i have a 7mgte with 560cc injectors, lexus afm, 3in turbo back exhaust, 1.2mm head gasket, front mount, spec stage 2 clutch, with a map ecu to tune, not tuned yet thats y i still have lexus afm still on, just wondering if i will hit 400whp or am i going to have to run 100 octane or higher grade fuel, i also took 60-1 off for a 70a/r intake with a .68 exhaust, didnt like the spool of the 60-1

 

[turbodriz]

what was wrong with the spool from the 60-1. That is the turbo that I would use for 400 hp if that was my goal.

 

[MKIII TURBO60-1]

i would keep the 60-1 if i had cams to spool it faster

 

[suprafanatic]

does the map ecu alow you to remove the afm? also what 60-1 turbo are you refering to?

 

[MKIII TURBO60-1]

it does but u have to be tuned by someone that is trained to tune map ecu, its an ebay 60-1, its my lil beater motor, got another build je pistons, crower rods, main caps, cams, gt37r going for 700whp

 

[frontierguy25]

Good luck with that Map ECU, I have seen several of them blow up 7M motors!! If you are going big power go with a standalone!!

 

[MKIII TURBO60-1]

i plan on it, this is just temp, im going aem when the other motor is done

ebay turbo ftl

gt37 can not get you in the 700rwhp, more like a gt42 at like 30+ psi, definitly standalone

But dude it's a 37 that's bigger than a 35!!
(or so he seems to think)

Pretty ordinary comment! i've seen stingers wreck motors cause they weren't tuned right, can't blame the ecu just the tuner or the engine.The map ecu is great if it's used for the correct purpose, For example my latest car was previously tuned with a map ecu and ran great got good fuel economy and made an easy 375 rwhp with just a 60-1 and 550 injectors stock bottom end with 1.2mm m/head gasket .The combination is cheap and tuned properly had great results for money spent. The car then had the map ecu removed and had a stinger 6860 installed with a stinger ignitor by so called professionals who actually made less hp on the dyno and also screwed the motor in the process.
The moral to the story is get a good tuner not a wannabe otherwise the end result no matter the brand ecu will be the same.
I would never recommend a standalone to someone only chasing 400 rwhp when a properly tuned safc or map ecu will do the trick and be relatively safe as long as it's kept within safe timing limits.

lol i love how someone can tell me that a 37r wont make 700rwhp but on a lil old 4g63 in an evo can lay down 700whp with a 37r, i want a drag car not a dyno queen

Show me a 7m that makes more power then a 4g63 on the same turbo (similarly equipped). I firmly believe the 4g63 is a better engine then the 7m. There countless evos making 650+whp through a 35r. I doubt your car will make 700 wheel on a 37r, but I would love to be proven wrong! On an evo, yes, on an undersquare 7m, good luck.
That being said, there is a lot more people *properly* equipping evos, and a whole lot of teenagers with hackjob 7m turbo kits expecting similar numbers. I don't believe the limits of the 7m have been tested due to improperly tuned and equipped setups.
As for the map ecu, I really liked it. Lots of tuning points, uber easy to use, and there are enough people out there with it to troubleshoot. I had no problem using mine. My motor gernaded tuned by a map ecu, but it wasn't because of the tuning. Most motors don't like it when the fuel pump goes out during a 4th gear pull! The biggest downfall of the map ecu is lack of timing control.
For example, if you are running 720cc injectors (that's what I ran with no probs). Under WOT the map ecu tricks the ecu to use the 61.1% (440/720=61.111%) throttle input. Ideally, you would want a 100% throttle timing map, and 61% throttle fuel map, but the map ecu doesn't differentiate between the two. The map ecu leaves more horsepower on the table with bigger injectors. It also has less and less control over timing maps making it easier for your motor motor to go boom boom.

heck na man no replacement for displacement:evil2:

Why did i wrote 700rwhp? was it on the post?

I was referring to MVP and Powerhouse, two of the biggest Supra tunners out there. Call either one of them and they'll tell you Not to run the Map ECU on a 7M! Trent that worked at MVP and had everything for his car built by Powerhouse, his car did great at the 400rwhp mark but at the 500rwhp mark the timing was everywhere! They couldn't control it and it blew up the motor finally! I have seen other Supras as well at a local guys shop that only works on 7M's and seen 4 cars come into his shop with the Map ECU with blown up #1 Cylinders.

I like how the Map ECU works, especially the Map ECU 2. The map ecu 2 has timing control but it can't control our ECU and Timing. The biggest downfall of the 7M is the ECU! Once you get away from it people have done great power! Like Xman with 750rwhp on a stock motor!

And for the comment on the 7M vs the 4G, there are so many more options out there for power mods for the 4G motor. So many people spend the money correctly on the 4G and build it. The 4G is a square motor, with a better flowing head, it is going to perform better. If you look at all the big power 4G guys they are running 35+psi on their motors to get to that big number. There is a guy on here that posted up a 1J motor with a 35r with 30psi and had 600 rwhp! So with a little more displacement and some head work I bet you can make 600rwhp with a 35r on a 7M. It's all money.

Honestly I kinda think of the 4G motor like the 4 cylinder version of the 2J.

Like i said, if it is used for it's correct purpose then it's a great little fuel computer, if you are after more than 500 hp obviously you'll be needing timing control at some point but there's a lot of people that are happy at 300-400hp for a daily and for that purpose it works great once tuned properly.

No, its not good for anything. Map ecu on 7m is notorious for blowing the motor on I think the #5 piston, I know my friends shop had 2 cars in at the SAME TIME for the SAME PROBLEM, both caused by using map ecu 1 on a 7m. Do not do it. Its not a matter of tuning, it is a hardware glitch.

Thanks for the back up Jon! I've seen 4 #1 cylinders blown up because of the Map ECU and they were all tuned by great tuners, just they don't do very well with the 7M. Like I said before, the only way to unlock the power of the 7M is to replace it with a 1J or 2J or go standalone!! Myself included!
