My hard pipe kit is the same as what was used by jamsport when they first developed the kit, there has been many alterations to it, its a very tight fit squeezing it behind the headlight and around past the foglight to the intercooler. I have no idea how much it would cost but i imagine it would take a while for anyone to work out etc. Yes the filter is very low but is pretty well covered by the plastic undertray, am actually looking to replace the filter soon as its pretty badly worn on one side where it rubs against the radiator. Yh spare a few hours to get through his thread but its basically what allowed me to fit the kit. and in terms of maintenance, yh check oil regular and also oil filter will need replacing when serviced.
Also where are you from? if you ever need measurements etc i could bring the car to you if its a reasonable distance,
cheers

Didn't know there was another option that had been tried mate, any idea where i could find one from? All the other stuff i want to get for the car is making me feel like Forging is a lil ambitous for this year atleast. Paul reckons I'm looking at 4K for a forged block that will be worthwhile with uprated clutch and stuff also. Rather have the rest of the car in Mint condition before i spend more than half the value of the car on the engine.
I'm a million miles away in scotland lol ! So do jamsport still do the kit.....? Couldn't see it on their website, not that I can afford a new one atm , but would be good for the likes of pipes and pulleys etc ! I take It your intercooler came with the kit ? Yeah I'll get on that thread , I'm sure a lot of questions will be answered ! This is all making me excited now haha, need to start saving the pennys !!!!

You will need to save plenty, and dont think there was any more than 2/3 ever made as far as i know. i only know of one other that is still supercharged. thats why i managed to get it all for under 2k as i found one of the few kits that exist. and yh the intercooler came with but just been looking at cazan racing site and sure there would be a intercooler that would work on there

I'm on it right now ! Looking forward to hearing more from yours and some videos ! Cant what to see what's planned for it !!!
What ever you do don't get one from there!! You may as well burn your money! Trust me! I've wasted thousands! 6k forged engine dead in no more than 12/15k miles!! There mapping is awful! Only this kit and another exist. Both from JS on both mapped elsewhere because they messed them up.
To do this conversion properly they need forging. That's why no one bothers with it. To buy this kit in and out is about 5-5.5k, the. Forging is 4k. Fuel system 1k. That's over 10 already before you've considered Coilovers, a diff which is essential, brakes etc. You could turbo it for cheaper and it would wipe the floor with it. This is unfortunately why it's not a popular option.
The intercooler needs to be small as the charger is placed next to it. My advice is find somewhere else to mount the charger and then get a bigger intercooler. U won't be able to fit anything bigger otherwise. My intercooler for my turbo is a good 3rd bigger and twice as thick because now I have more room. Ktec have mounted there charger in a much better position. I'd call them and sort a kit out with them. Then get RS tuning to map it on a standard ECU to save money. Either way it won't be cheap for you.
Also I wouldn't worry about the clutch, your not getting a huge spike of torque like a turbo, mine lasted ages. Had about 20k miles of turbo and s/charged hammerings and about 6/7 track days.
Engine is where u need to look at 1st, and updating the fuel system. You'll get nothing past where u are now without it.

totally agree with mike and im taking a huge risk which will probably result in me going insane. If im honest you would 100% be better off buying a megane engine or even a full car and breaking if you have room.
plan was always to eventually forge my block even if i went down the turbo route, and if i need a block doing cos this has blown up, i have the funds in other assets if i ever need them urgently

May I ask, can't you just run the supercharger with lower boost or something and have around 240-250bhp? In that case you won't have to worry about forging it or any other reliability issues and the car would still be strong. When I went out for a spin in Ktecs charged one (running at the time around 240bhp) I was impressed with how quick it felt, yes not 300bhp turbo quick but still seriously quick. Spending £4k+ on our engines just to forge it and make it reliable is madness!
Also, why is this route so expensive on our cars? I met a guy in Brands the other day who had his speedster 2.2 NA supercharged for £2.5k all in.

from what i can tell its not as simple as turning down the boost, you can put it in a restrictor plate which is looking like the best option atm which stops as much airflow and you can also change the pully size but you cant change how fast the aux belt runs the charger.
trouble is the compression is high in the standard engine and is always going to limit it unless engine work is carried out.
and considering that the charger retails for 15/1600 pound its already a huge price without intercooler, piping, oil cooler, mapping and labour of course

It's ALOT to go down the forge route, I had thought Of a Meg conversion but the keeping the n/a like Rev range/drivability on a supercharged car just appeals to me , I wonder if 240-250 would be reliable on a standard engine , as Id be happy with that! Not looking to go mega on power ....,! 4.5k for forging , **** me , how much are the parts? The labour must be the big cost! Thanks for all the advice so far guys ! Tomd197 what route do you think you'll go down in the end ?

Can see me going for the restrictor seeing as though it would give me a more reliable power rate at least for the time being. Will be looking to build a new block later this year and in to the next so maybe this time next year I can drop a new block in but its all speculative. If a good opportunity comes to drop in a 250 engine and have it running for around 4k then that may tempt me. Brakes, suspension and tyres are next on the agenda I think, probably around may when I need to service the car. Will be seeing how much it would cost for a restrictor sorting by Paul and that may happen this month :thumbup:
Forging isn't cheap mate, it's not just Pistons and rods. When supercharging you 100% want to uprated the valves, I found out the hard way, with Fernandez as a passenger, a **** map didn't help but you don't wanna pay 2k like I did when it could be done for less than half with a forge build.
