How much have you stripped off it?
Front end so far... I've pulled apart the bumper mounting brackets. The chassis rails then crumbled in my hand as I fiddled with more, rad's out and the carb/ inlet assembly will be off by the weekend (when I get time). So I haven't delved too far into stripping it. But I'm going to have to pull the engine to get a decent idea of what the front end really looks like.

The more I look at it the better it seems.

Has anyone boxed off the front end and welded/ mounted a crash bar holding the bumper assembly? Is it MOT legal fro experience? What I've read on the net suggests that it's all ok as long as it's mounted properly, but then is it over modifying the vehicle?

Cheers

I guess this all boils down to personal preference as well as driving style...? How does it reflect against fuelling... Is jetting the carb a cheaper option?

bridgeport is just a compromise for racing where peripheral ports aren't allowed. A peripheral port makes more power and torque low down and smoother running. My half bridge 12A is not a good set up for road use. If I wanted to build a good road engine I'd just do a large street port, or semi PP.
Just to clarify, is peripheral porting based around the inlet ports? Like siamese ports on Mini's? Or is it much the same as bridgeporting and the like?

yes it comes down to preference, some people think bridgeports are a good idea, some people think its a good idea on the street. For me bridge porting is just overkill for street, in the real world by the time a bridgy has finally got to the revs where it starts working, a street port would be already up the road. I have a half bridgeport and it would be fine on the track but on the road its not the best idea.

rejetting a nikki is probably cheaper, but harder, than getting a standalone ecu, efi and mapping. the other option is changing to a more easily tuned carb like a weber 48IDA.

peripheral porting is sealing up the stock side intake ports altogether and cutting a new hole in the housing, like how the exhaust port is. It works much better than a bridge port, but takes more work. bridges can be done cheap.

After a couple of months of avoiding rain and cold weather. I decided to roll Homer out of the garage to create room for what’s coming off ready for sandblasting and welding. Especially while I ‘work from home’.

Safe to say, I didn’t expect to find as much damp in the needle felt under the carpet as I received... but that might be down to sitting outside for 5+ years with a boot that didn’t latch.

Pictures attached for your enjoyment folks... some of the rust has displayed itself in places I didn’t think possible, like the driver seat mount. Both rear tubs have been patched too, but for some reason, they just plated over the rust??

On a side note, where do people go for replacement nuts and bolts? No amount of WD40 is saving some of the bolts I’m taking out, 3 of which were from the 4 holding the rear bench in :thumbdown:

More to come over the next coming days! Stay safe everyone!

These bolts are no problem to get on mainland Europ. DIN 6921, Mertic M5, M6 and M8 are standard threats, M10 and M12 are fine threaded.

Yes RX7 forum is a good starting point... KevinBTZ has a good write up on doing the rew/cosmo swap... he built my REW engine and I did everything else in my resto/build.. see my thread about 2 down from this one... (or click - http://rx7fb.com/viewtopic.php?f=4&t=4049 )

Also DreaminRotary on the RX7 forums has some extensive write up somewhere on the s4/5 swap... He is local to me and one of my mates.. small circle here in MN, USA...

as far as the rust, if you are going to pay out your butt for someone to weld it, I would say spend a little of that cash and buy a semi decent wire feed with a gas tank and learn to weld... maybe buy a small metal brake that can handle sheet metal at the thinner gauge.. practice practice practice... in the end it will be rewarding and a learning experience...

then you can sell your services to fellow people who are in your position and pay for it all hahah

good luck mate..
