    Engine conversions which to pick?

    I'm really thinking about changing my c1j for either the Renault 19 or the Williams but I'm very stuck as to which ones best and easiest.. Come on guys which should I go for? Seen some nice whole cars on eBay for about £1000 I recon I could make the money back after breaking the cars.. Talk to me

    dont do it. Unless your going to turbo one of the 16'v's, a non turbo engine in an r5 to me is just dull.

    Re: Engine conversions which to pick?

    If I wanted an engine conversion and wanted to stick to turbo I'd probably be looking at dropping a Megane 225 lump in. I'm sure there's quite a lot of work involved in that but It'd be worth it!

    Re: Engine conversions which to pick?

    Project reports would be best to look for ideas. Looks at Robbies F7P if going down that route, or a lot of the norwich lot and ipswich done the conversion, mines in the process of being changed over to silly power. Or even look at Penfolds F7P running bike carbs. Got Ashy F4R turbo conversion, Scoffs conversion are all great to read

    Re: Engine conversions which to pick?

    How much power are you after? Anything over 230 imo an engine conversion is a good way to go, anything upto that and you may aswell stick with the C1J.

    1.5 Bar from a decent sized t25 or a t28 if you can deal with the lag, with the right spec engine should see over 200hp relaibly

    My conversion is a cheap conversion... Not a Powerful machine, i am not interested in 200+bhp

    I will be lucky to get over 160... But its the way it drives.... And the sound oh and its cheap... I think my car owes me around £1200 (including buying the car, carbs, cage, buckets etc)

    Well as much as I can get for as easy as I can get really I do t want to spend 1000s on fabbricating I really want it to be a backstreet build. I will take on all your guys knowledge as you are my experts.. I already have the t25 tomcat but i just find its pushing the little 1.4 a bit too much I haven't been disappointed yet by it but we always want more bhp for our £££
    I will get reading and see which way to go.. Looking on eBay there's plenty of choices of cars to pick from its just which fits best for me todo in my limited garage

    Cheers guys

    engine wise you can go for the 1.8 16v out of the early clio or the 2.0 16v out of the clio williams and of course the clio 172/182 engines, all these are ripe for some forced induction, im defo no expert with these engines but id imagine you will need to go forged for bigger power though

    I haven't as such I just want to do things myself here at home and I wouldn't know we're to start efi wise? All pointers would be great.. I'm going to read up for a while and see what's possible.. Basically I would have a bag of sand to spend.. Not a huge budget I know but it's we're I'm at.. Thanks again

    If you have only £1000 to spend on doing a turbo 16v engine then your best of staying with the C1J, to do it properly your need abit more than that i recon mate.

    If it was me i'd have £2000 spare, there are alot of little bit that you never think of that always put the bill up
    Just off top of my head you'll need to machine the pistons or fit new ones so the comp ratio is right, poss full gasket set once you pulled it apart to do that, new exhaust manifold, a suitable turbo, downpipe, new oil feeds, mod block for oil return, ecu, injectors, pipework for water and boost, intercooler, etc

    If you got a £1000 you could spend it on the current engine giving it a freshen up and tweek here and there, it'll still be a strong engine mate and easily keep up with mordern motors

    Re: Engine conversions which to pick?

    The B18FT is a much more realiable and better built engine plus it has the bonus of having fuel injection.
    To get them around the 200bhp mark it doesn't take too much to do, a case of bolting on some new items of other cars and then setting it up to make sure it fuels right. The basics will be a different camshaft (one from a Clio RSI works), T28 off 200SX, some Volvo T5 orange injectors, nice free flowing exhaust and better intercooler, de-limited ecu and your be getting close to the 200bhp with a it of boost too.

    To explain how the carb work will take an age, there's alot to write and also how to tune them does take while to explain too. The knack is drilling or reducing the size of the right jets and not just increase the size of the main jet, it would take alittle while to do as you'll have to keep taking car for drive to see how it fuels and then mod it again.
    I've been doing carbs for pretty much 10yrs mate and they finally have done my nut in, for me fuel injection is only way.....

    This seems more my capabilities and good power and gears??

    Re: Engine conversions which to pick?

    I think what I should of done was ask for a passenger ride in the different engined 5s before making my mind up... I'm not diving into anything I will keep reading and keep watching.. It's Definatley coming off the road after pod so I have plenty of time.. Who has what conversions on here? I'm not going to be selling the 5 it's here to stay just Fancie something different.. Can't beet the comments I get off passes by the best one so far was today when I guy in his late 40s pulled up at the side is his family wagon both windows down and I heard him say " Renault 5 gt turbo you don't see them anymore.. So I looked over smiled and he said there like popping a cork" I smiled and said yep I love em.. That's when I thought need more power

    Marts correct, after 200hp c1j's are completly bonkers, I honastly don't know how people get on with circa 400hp in a five fifth gear must just about be usable........


    I have said it a few times now, since all these engine conversions 400hp is the new 200hp......

    For me, stick with the c1j and spend that grand wisely and 200hp will be yours.

    and even after i lent you my 5

    imo, volvo. best value per £ compared to other conversions unless you want 250bhp. most people who've done the conversion sell their setup for more than the cost of the whole volvo car! (usually less than £500) it has efi, extra 300cc, already turbo'd, no liners, no push rods and will run 175bhp in std from just by upping the boost and a scoff mod for less than £50. takes alot of abuse and will do all day long (unless you trap the ecu vac pipe behind the dash!)
    valvers and williams engine would be the next step, requiring alot more bolt on bits to make it turbo'd, prob double the cost of the volvo but prob still less than making a gtt efi to the same power. then next up is the 172 which wants harder to find or more custom bits but offers more gains in the long run. think you want to figure out what to use it for then go for a few passenger rides.

    thats right im sure he will sort you a good deal as well , id start with your cam, no real need for headwork, i only had it done as the engine was in bits for ages so it was rude not to lol

    a good set up and run around 20-22psi should see you break the 200bhp barrier.

    what mart says was true re 230bhp mine is just over that mark now and its bonkers my little neice loves it haha.

    [quote=Haz;287144]and even after i lent you my 5 /[quote]

    I have to admit looking back when you lent my your five it was the Volvo lump with over 200hp, it was actually quite delightfull, efi made off boost driving much smoother. As an "out of the box" efi'd turbo'd lump it is probably the best way to go engine conversion wise on a limited budget.

    I just can't help but love the c1j and now I have experienced one with similar power to your old Volvo lump I think it keeps the character of a GT turbo. I love the old c1j burble and when you hear one on full chat, well, they just sound awesome

    I do however remember you absolutly used to kick your Volvo lumps head in day in day out, did loads and loads of pod runs with it and it never missed a beat. Weather or not I would do that with my c1j I'm not sure

    but surley the gears dont match the power? the little gearbox struggles now so what would it be like with another 50 horses?
