I live in Michigan, and I've owned an FB since 1989. My current car is an '84 GSL that is fairly heavily modified. I like trying new ideas on my car, so it's a rolling experiment:

- 13B-RE engine
- GT35R turbo
- Toyota 8" rear axle
- Tri-Link rear geometry with horizontal Watts Link
- One-off front big brakes

I do track days with a few clubs, so my car gets some exercise.

Welcome to the forum Elwood, your car sounds like its a bit of a beast, any chance of some pics ?

Here's a link to my website. It's out of date, and some of the images disappeared, but it conveys the general updates to the car --> https://sites.google.com/site/elwoodsturbofb/Home

Hi Elwood,

Great build information, alas G Force are no longer trading, as I would love to get hold of a copy of his book.

Love the mods.

I live in the US, and I've mostly followed a certain US-based forum. It's refreshing to see all the products and methods used by enthusiasts in other countries.

I Elwood, welcome.

A few of us on here have also looked in to a certain US Forum over the years but got our noses pushed out a bit by blunt comments from moderators if we went off message in any way.

On here we like to think we're a bit more open to other views and comments.

Glad you're posting.

Cheers Codge.

Hiya, welcome over this side of the pond. Thought I recognised the username and car history from that "American forum", lol. I dunno about the moderators specifically, I think a lot of us guys from outside the U.S. found it a pretty unwelcoming place in general, which is a massive shame because there are some awesome builds and engineering on there, and it is pretty much the fount of all wisdom on RX-7s. But it's very frustrating trying to find it, and you have to grit your teeth and be willing to grow a very thick skin

Nice car and website bud!

You are running the same Injectors and Pump as me, interesting to see that you bumped the fuel pressure up and showing the corrected flow at 5bar - I thought the same thing, but the injectors match the flow of the pump at 3 bar so I couldnt see any point going higher.

The 044s are rated at 240lph @ 3 bar, which is 4l/min or 1000cc x 4 = assuming 85% duty cycle, thats 850cc fuel at that pressure (slightly less from the 1:1 fpr but ignore that for a second)

200lph @ 5bar = 3.33l/min or 830cc x4, so that would be a lower injector duty cycle (70% ish), but no pump headroom, so more likely around 750cc.

Love the fact you have detailed everything though - would be great to see some up to date pictures too!

I raised the pressure for two reasons:

1. I was an early adopter of the ID1000s. Paul Yaw is a friend of mine. He showed me the atomization at elevated pressures, and it was slightly better.

2. I'm running a fuel pump booster, so I should get more flow due to the higher voltage. BTW, I ran some free flow tests on the -044 at 13.5V, and their flow chart was right on the money. That was with a filter sock on the inlet, the Bosch check valve in place, through 4 feet of 3/8 inch hose.

Welcome.

Nice website and car mate. Thanks for sharing.

That US site is full of idiots. I'm getting the runaround on there at the moment while looking for a rare (in Euroland) part.
