Hello there everyone,

I have decided now to create a blog for the CRX project that I am undertaking. The car is a 1.6 16v MK2 CRX with the D16a9 (non VTEC) engine. Its going to mainly be a track car as well as a weekend toy for a bit of a hoon about in smile

Plans are to turbo charge it and I already have a full greddy turbo kit with a zdyne ECU that is already mapped for this exact engine. On the car it came off it was pulling 174 BHP and 158 Ib/FT. In a car this light its going to be fobbing quick! This is going to be fitted once my mate pulls his finger out of his behind and comes back from Majorca.

So enjoy: http://turbocrx.blogspot.com/

All comments are welcome.

P.S. I am aware that it says tt on the windscreen in the first pic, no doubt my brothers handy work.

ETA start at the bottom and read up.

just a few pointers. firstly good job sorting out a crx. i put one back on the road this year which would be in the scrappy by now if i hadnt sorted it all out. fibreglass is handy stuff, but only for cosmetic stuff. personally i would cut out or at least patch weld the sills rather than cram them with filler. much better in the long run.

Mounting the harnesses like that is Extremely dangerous. If you have a frontal impact the seat will crush and you will be forced down because of the low rear mounting point which will cause serious spinal injury. also using harnesses without a good rollcage means you are held firmly upright in your seat and if your car rolls the roof caves in on your head crushing you as you cant move down or to the side. Ideally you want a rollcage and strong bucket seat if you use harnesses. If you decide to use them, an often overlooked mounting point which is ideal is hidden behind the plastic covers on the rear inner boot roofline for mounting 3 point belts in the back. if you look closely you will see a wee dot on the plastic to tell you where to drill the hole to find it. it is a proper re-inforced belt mount point probably stronger than the rusted floor ones. it is at the same height as the seat so will illiminate the spinal injury issue. To be honest, i tracked my CRX and had absolutely no problems with standard belts as the 16v seats are very supportive and not covered in slidy leather!

Key thing i noticed on track were brakes overheating and fading. get some vtec hubs and do a rover brake conversion and/or at least get some ducting to channel air to your brakes to cool them.

Hope the build goes well.

The inner sill is fine thats only for the outer sill, I haven't filled any of the inner sills.

Thanks for pointing that out, can you explain the forcing down under a front impact a bit more, why is this?

Also thanks for the tip about the other mounting point I will take a look at this tomorrow. Is it defiantly there on CRXs?

just search the crxuk forum under harnesses for info. my 16v had the rear mount points so yeh they should be there. the spinal compression issue is caused basically because your sittin with a loop of belt over your shoulders attatched to the floor rather than at shoulder level, therfor in an impact it will force you down rather than stopping you moving forward. just use standard belts theyre much safer.

What a deathtrap. Those sills need to be cut off and replaced, doubtless the inner sill structure within them will be shagged too.

So the outer part of the sill is not structural then?

If that's the case why is it not a plastic trim?

Woah... Not the way I'd fix rust, that's for sure.

Love CRXs... please do the job properly smile
