87 Sun Sport Overhaul

[sybrmike]

I used a "sharp shooter" shovel to cut the foam from the stringer edges, then into ~6" square blocks, then pry the foam out in sections - kinda like carving brownies outta a pan. A 4" putty knife made a good scraper. Messy, tedious work for sure, but looks like you're making good progress.

rlhahn - the loading on the platform brackets is vertical, so you're better off making the backing plates taller instead of wider. I really like how Okie's go all the way up and capture the tow rings as well. Here's a shot from his thread that I saved cause I'd like to do the same...

Neil - Thanks for the nice words; like you said, it makes me happy to give back and help spread the Supra vibe. I wish I could work with boats more but it's a great hobby too.

Rlhahn - For the price, you will come out ahead in the long run. It sounds like you are mechanically inclined, which helps lol. We will be watching! While I wouldn't discourage you from posting here, I would encourage you to start a thread of your own about your restoration so you can get our undivided attention and get all your questions answered at length. What year and model did you get there? Oh and describe your on the water activities to us. Family or buddies? Ski or board/surf or mix?

SybMike - That is a GREAT shot! Important area to know what is going on back there.

To add some description to the picture sybr posted...

It appears as though there was a build up of plywood and glass to make it a couple layers thick, then the tinted gelcoat or bilgecoat was coated on. Finally a piece of 1/4" thick aluminum plate was adhered to the surface and that's what they used to bolt through. The swim deck and the rear transom strap hooks all use that area for support on the left and right...definitely very solid! You can see they also did that in the middle up top and toward the bottom for the tow ring and for the middle swim platform support, respectively.

I think you might have a HD 3/8 plate back there.

You're right, I'll do it like that. Thanks for the pic.

I've been wanting to start my own thread, but can't figure out how. I may be mechanically inclined, but I'm for sure not computer savvy...ha! Any help?

Pretty simple.

After clicking on Supra modifications, you'll see a button at the top left that reads "New Thread". It's a blank slate for you to call it whatever you'd like and you can start posting your work.
Good luck!

Just did a coulple of hours measuring the floor (from the cockpit back) and I came up with only 55 sq feet of flooring, which seems a bit low. How many 4x8 sheets of flooring did any of you use for you projects?
Just wonderin
Thanks

Met with the mechanic today. Although I had no plans to mess with it, looks like I'm going to have over 300hp!!

I'm also having my engine rebuilt. Just wondering what type of modifications are needed to go from 240 to over 300 HP. EFI?

[NeilMcg]

We're using a Summit package that includes a new intake,cam, lifters, rods rockers and flathead pistons which will bring compression to approx 11:1. Special ignition changes are also in the works. He's betting on 310 once on the dyno. The ft/lbs are another thing which needs to be addressed.

I looked at EFI, but it just wasn't worth it. Too much electronics, fuel return line...Had to put the brakes on at some point with this thing. As a 'footer, 44 is my max speed I need anyway. It'll just be nice to get it to 50+ for show!
