My personal choice for this same HP goal for my Del Sol is using the typical Vitara build (but bored to 76mm due to a previous 75.5mm build with oiling issues) and a t3/to4e 50 trim... It will be slightly laggy but should spool up around 34 -3600 rpm and pull to redline... That being said, I have alot of work to do for traction issues below 3rd gear... Fortunately I actually know how to "Drive" a car instead of just slamming the gas to the floor and hanging on as so many of the younger generation tend to do... They just dont realize that the throttle is not an on/off switch... I have tentatively named them "togglers"... LOL... Either way, the lower HP car can actually be faster because of the traction issues with FWD...
To the OP... Good luck with your build... Take care of it and enjoy it and keep up good maintenance and it will last you for quite sometime... Anythings less than that and we will be reading about your next build very soon...

Though, maybe I'm not looking at the same turbo...?How much extra displacement do you get from the 76mm bore?
We're running a mitsu TD04 13T (stock turbo from an impreza WRX) on a MK1 87 MR2 (built for autocross and road course) with a 4agze converted to NA manifold with a water to air intercooler and megasquirt standalone. With that turbo on that 1.6L, peak boost hits like a brick wall at 3000rpm and holds all the way to the limiter at 7500. Right now we're running about 13psi boost and making about 240hp. It's unbelievable how an engine performs when you match it to the right turbo so that it runs in it's most efficient range... 70% at 3000rpm, 76% at 5000rpm and still above 70% at 7500rpm (limiter).
A properly, well thought-out setup will not only net you the numbers you're after but it will also net you more usable, safe power and a car that's very fun to drive.

Meth injection is an option. But don't you think it would be less of a hassle to simply run a slightly larger turbo vs a meth injection setup?

I have everything for the meth injection and i dont have a slightly larger turbo.
The 76mm is .40 or 1mm over bore. and i dont think you are lookin up his turbo. Hit is the t3/to4e 50 trim hybrid.

MPR... Here is the Link to squirrel performances calculator showing my intended application... You likely looked at hte standard "50" trim... i am using the Super 50... Horsepower goals are the same 325 - 350 ish on moderate boost with pump gas and 400 ish on more boost on race gas...

Yep. I was looking at the standard 50-trim before. I also use squirrel performance turbo calculator quite often to check maps. It's fairly accurate. It's bang-on for our MR2 with the TD04 13T.
This map shows your engine on that turbo at 350hp:
(map might be a little off... forgot to change the target AFR, so it's at 12:1 for this map)

^It's up to you. They recommend replacing the belt every 100k or so. Not a bad idea to install a new timing belt and water pump while it's apart. Peace of mind and a little added insurance. Use a belt and water pump from honda, not some aftermarket brand. Tensioner should be fine.

It is a Honda belt thats on it. Also have a new Honda water pump already. Got the head off and found a burnt valve. Can I clean the carbon off all the other valves with a wire brush on a angle grinder or a cup wire brush on a drill?
Not the slightest ring lip on the cylinders. So should be able to do just a slight hone and put all the forged internals in.
