7MGTE Build up suggestions 350hp - 400hp

Cre, thanks for the input. Ummm, well the shop around here gets a lot of biz, but how do I get a good tune? I mean.. I have 0 knowledge of the tuning aspect of things. What I mean is it sounds like a bunch of computer and math stuff. Where can I get some knowledge on tuning it. I mean, you guys here do an awesome job doing your cars on your own. I been doing more and more on my own and saving TONS of $$. How would I get the tune knowledge in my head..

(I was thinking tuning had to do with the ecu + all your mods that can equate into the HP/TQ Performance factor)

What bottom end mods would you call good to keep my engine going at 350hp - 400hp for a long while? Also, what top end mods would you suggest if any?

I want power and reliability.. I don't want to keep having to crack her open due to other failures. I would like to get it done right so she runs the marathon hard and long!

Your car can only perform as well as the software tells it to... shitty tuning equals shitty performance no matter how good the hardware you've put in is.

How you tune varies a bit from one system to the next but the overall target values remail the same... when you get past the basic "get it running" level the tuning becomes very specific to that one engine... every little unique thing and all of the end desires require someone who car really feel it out more than just rust read the numbers and press buttons. I can't really recommend any one good source for reading up on tuning... haven't found any really. You just need to learn the theory and start doing it. I did read a bit and I started tuning my old N/A then I tuned a friend's car (retuned both of these MANY times) tuned a built Supra out here.. then another... and so on. Start with some "seat of the pants" tuning with an old Honda and then try tuning on a couple dyno runs... THEN work on the Supra.

This isn't one of those things I recommend that people do themselves... a couple digits off and next hard run you've melted a piston. It's a good thing to learn, but a lot of care must be taken.

You're really fine with a stock build (maybe some slightly more aggressive cams). I'd rebuild the bottom end (by the book), replace oil squirters, oil pump, pistons and rods would be excellent; and then I'd aim for the upper 300's.

Just one thing I'd add on the spark plug side of things, I don't know what anyone else's experiences have been over the last year or so but I felt that NGK plugs had lost that certain "something" (had endless fouling/misfire issues on other vehicles & not a few open-circuits in the resistor type plugs on my bike).

That said, the platinum jobbies in my supra when I got it have been just fine and are back in it now!...

I hear that all around, but I see a battle going on with believers and non believers. I am sticking to the NGK side and replacing them with the stock replacements of NGK Laser Platinum. Well at least all the computers at the shops keep coming up with it as recommended, some even say it was stock.

NGK is what the car came with... regular NGK platinums. They're what you'll get when you buy "Toyota" boxed spark plugs.

Fouling is due to either running excessively rich or running the wrong temp. If you haven't changed anything on your car and are running the same temp plugs as always you've most likely got a fuel management problem somewhere (usually the AFM).

If you want to use a different brand make sure the insulator on the wire side is the same length as the NGKs. They're not made to the ISO spec which is shorter.... people have had a lot of trouble with fouling using ISO spec plugs if the boots don't seal very firmly (see: unless the wires are pretty much NEW).

Ya, I will be going with NGK laser plats... <---Love this one
