Making a new inlet for my budget trackday hack
Not going to get the yellow clio done till next winter as Ive got a couple of cars I have to finish before I can start it (my nova and corsa) so to allow me to use my "pikey motorsport" blue clio still this year now that I have sold off my throttle bodies (to help fund the yellow clio) I decided to knock up a new inlet for it rather than go back to a standard one.
I had a spare carb manifold lieing around, and a spare pulsar plenum that Doug (garage19) had previously modified to bend the inlet to it back to clear the ABS on my calibra which just happens to sit it ideally for what I want, and Neil Adams still had the drawings for the spacer and backing plate when we did a similar inlet on his turbo westfield, as he has been selling them to people, so he got another set made up for me as a thankyou for mapping his car.
Adam (aka dewis motorsport) is going to weld me on a flange to take a cosworth throttle body as Ive said I'll map his car as well, so fingers crossed all its going to cost me in actual money is price of a secondhand cossie throttle body for the whole job
So this inlet actually owes me nothing but a bit of time and reciprocated favours which is far more in keeping with my budget theme for this particular car than the throttle bodies ever were, lol, and its coming along nicely so far.
This is how it looks mocked up on the car to check it will all fit:



Could be ran on the standard clio management now too as it can give a map sensor signal like the standard management requires, but im not going to remove my Mtec V4 from it as Im too fond of it and I havent got an emulator to map the standard management with anyway.

Yeah I dont think power will be effected much from the swap from ITBs to this setup.
Acedemic anyway as the rings are on the way out, so i'll lose far more to that
Hopefully still give your clio a run for its money at bedford though

Got some more pics now that its finished, showing the trumpets and the work done by Adam Dewis (dewis motorsport) for me to fit up the cossie throttle body, he made up a flange, welded it on and put some steel rivnut inserts in it for the body to bolt onto 



Just need to add in a map sensor pipe somewhere now, find a filter for it and get a new gasket and it should be ready to fire up so I can remap it, so hopefully get a day free to do that in a few weeks when I have some time off work.

Fair play Chip, you clearly love working on cars and appear to be fairly talented at most things. Have you ever thought of doing it full time or are you in a pretty well paid job now so its just a hobby?
For now I have a couple of reasonably well paid jobs, main one is 4 days a week as an IT consultant for lexus and toyota and then a part-time job as a freelance motoring journalist for the rest of my time. So certainly for now it makes more sense as a hobby, maybe one day, but TBH I think that having to do what the customer wants rather than what I want to do would just piss me off

Me and a lot of my mates all help each other out though which is cool, like for example Adam who made welded up the inlet for me FOC has a corsa on DTA that he needs mapping soon which I'll do free for him etc.
A mate of mine has them made up after he used them on his Westfield.
It was his car I first suggested it for and he figured once he had gone to the expense of getting one made up he may as well flog a few off to cover the costs.
Its not just a backing plate though, if you look its a got a 12mm thicker spacer plate as well sat between the backing plate and the plenum so that the trumpets have more clearance.

hence tonights test drive lol. should have a new set of rear lights and astarter motor tomoz...
so just needs tax and the above lol.
its only 10 miles each way, but i think its pissing through fuel lol so only gonna get 50 miles to tank or something

Yup.
ST170 plastic, bit of silicon hose and your in. They don't line up 100% perfect, but not a million miles off either. Mine was fine on it, decent response, well made, pushed good power out of the engine. Ran it for over a year with one. Worthwhile cheap mod if after an inlet.
I've found that life I needed.. It's HERE!!
