So... I've been thinking... I've owned my NA 87 MK3 for a solid two years... and Im wanting more power.

I know the easiest route would be to do a 7MGTE swap, but my dads a Nazi, and wont let me (i just barely hit 18, and due to california smog.. he wont help me swap it in... :aigo: )

so i've been thinking... the 7MGE is rated at 210 at the crank? whats that RWHP..? 150?

I want around 220 RWHP, 200 at the least. And I've been doing research, I just want to hear some opinions on what steps I can take.

Im not too sure about milling my head wafer thin, and custom high-comp pistons sound expensive...

so what can I do...? Cams? Tuning? 2.5" exhaust? (i currently have 2.25" magnaflow catback)

my car is completely stock. I mean, all I have is a filter cone, and a mandrel bent 2.25" exhaust. I mean, I dont even have a MHG, just a toyota OEM HG and 20 year old head bolts (im pretty sure my 7M would have blown another HG, if it didnt throw its rod first)

thanks everyone for their input!

#1. Stock is 200 HP. If the drivetrain loss is 15%, then the power to the wheels would be 165 RWHP. If it was 25%, it would be 150 RWHP. It depends if you're using a manual or automatic transmission, but even then, the whole 15% or 25% figures are just guesses as to how much power the car loses and even then, there are theories which say that even the whoel concept of it is incorrect and that there is no way cars with low horsepower such as our N/As could lose the same amount as a car with 1000 horsepower, etc. but we'll leave that for another day :)

#2. 200+ RWHP = too much work for an N/A. Just go turbo. An Intake/Header/Exhaust setup won't net you THAT much power. To get over 200 RWHP, expect to do some major work. The stock design of the 7MGE is already good....other than the catback exhaust.

#3. Next time read the stickied thread that says "N/A Upgrade FAQ" or use the search button (which is also in the N/A Upgrade FAQ at the bottom of the first post). I'm tired of having to say this...

I've been down this road in my 86.5. I'll tell you, RWHP was (for me at least) about 147 with intake, exhaust, and advanced timing. The best thing for you right now is to just enjoy driving the car as is. Unless you a really dead set on having a 200 RWHP N/A, just leave it as it is.

Getting the 7M-GE to 200 is going to take quite a bit. Intake, full exhaust, porting and polishing, full balancing, higher compression (via pistons, not head shaving), fuel, etc. You could spend thousands of dollars building an N/A screamer, only to have your ass handed to you by a lightly modified (Intake and exhaust only) turbo Supra.

Don't waste you money, you'll thank me later.

Don't say that like it's a fact...some guys have more beat up engines than others. I saw a guy with a 7MGE in an MK2 run 169 RWHP or something like that, and he only had intake/exhaust...maybe headers, I don't know, but either way, it's more than 147

Kyle dynoed like 136 HP on his old NA he did have like 163 TQ though. that was all to the wheels. All he had was a mental bent intake pipe.

Would be easier to turbo it and retard the timing. I wouldn't worry about changing over to the coil pack for now if you just want a little over 200. N/A->T. Just leave the distibutor in for a while untill you can swap harnesses, and get all the other turbo goodies.

Rebuild the 7M - 11:1 compression pistons, a set of Crower 272 cams, port/polish the head, and a 150shot of nitrous on top of that to make for fun times against turbos :D

Do a basic rebuild maybe intake header and a catback and spray a nice wet shot,150 shot would be sweet on a NA. But you can always just look around for a cheap turbo car and get it smog ready.

lawlz @ the n/a haters.

For those of you bagging on a 7M getting 200+rwhp, just think of the couple 5MGEs running around with 189whp. Food for thought huh?

Those of you running around with 130-140whp, something is very wrong with that. VERY. My previous 5M was 132hp stock and then got 144whp after my 2.25" exhaust upgrade. That's a 12whp gain from a "shitty 2.8 liter 12 valve head". Healthy 7MGEs should be running anywhere from 160-170 STOCK. 200rwhp shouldn't be that big of a deal, just make sure you're not starting with an already flogged out, beat down 7M. Pull that bitch out, rebuild it. Hell, even bore it over .020 for an extra kick in the pants. Get a CAI, 2.5" exhaust, header, advance the timing a couple degrees, get some adjustable cam gears and start fucking around with those.

After my rebuild, my N/A feels like a monster :)(compared to it's previous state atleast :D), though I only have ported head and ummm....restrictive Audi muffler...
This header and exhaust thing looks too expensive for what it is...
