kane Posted January 18, 2010 Share Posted January 18, 2010 as title. i am getting a starlet sr and i eventually want to turbo it. i already have a 4efte engine in need of a re-build in my garage which i am going to take my time with. so while i am waiting i want to tune up the standard 1.3. does anyone know any good mods and would bike carbs work ok on it? i dont know much about these cars as i have owned and worked on vauxhalls all my life so any replies will be appreciated. thanks.

Kennedy Posted January 18, 2010 Share Posted January 18, 2010 Think Asad did some research into this..was a thread a bit ago..have a quick search Quote Link to post Share on other sites
micky boy Posted January 18, 2010 Share Posted January 18, 2010 Hello matey one of theys inlet manifolds off a toyota corolla bug eye should give it a bit more bhp not sure how much but it dose help it rev better through the rev range here a pic of it you can pick one up for £30/40 from a breakers yard Quote Link to post Share on other sites
mcbeal Posted January 18, 2010 Share Posted January 18, 2010 Hello matey one of theys inlet manifolds off a toyota corolla bug eye should give it a bit more bhp not sure how much but it dose help it rev better through the rev range here a pic of it you can pick one up for £30/40 from a breakers yard that would prob be the best power per pound mod compared to bike carbs as youd need a custom inlet mani made a set of carbs jetted to suit the car and no doubt management to get it all running well which would prob end up rather expensive.bogg bros do inlet manifolds for around 250carbs around 80+ then getting them setup, management 600?just to give you an idea.im sure someone had asked about this recently cant remember who tho hope this is of some help Quote Link to post Share on other sites
Asad Posted January 18, 2010 Share Posted January 18, 2010 Hey!!ITBS has never been taken on by anyone few have come close but have ditched it all for the FTE.....the gains are just not known.To get set-up you will need ITBS (750 variant seems to be the most popular)silicone joinersVelocity stacks/air filter arrangementInlet manifold to chop upManagement (to control fueling + spark)To get the best out of the air thats coming in you will need cams (this is where it gets expensive a decent set of cams will set you back £200+ i wouldnt go for the FHE ones for the 1mm lift or so there really isnt any point)Head work (port and polish)Uprated valve springs, the FE ones are made of chocolate and max out at around ~6300rpm so there not much use over a long period of time with a engine you will be reving high. The FTE ones are a cheap alternative but again you`ll have problems around ~7400 (the next option is aftermarket ones at £200 or so)After market header/exhaust system the extra air coming in has to get out quickly aswellRev gauge + shift lightIm not sure on how the fueling arrangement will hold up possible FTE fuel pump (if its bigger) and FTE injectors may be needed...that seems everything After all that theres the question of how long the bottom end will hold out along with the gearbox at such high rpms...A Quote Link to post Share on other sites
kane Posted January 18, 2010 Author Share Posted January 18, 2010 yes them comments are very helpfull thanks. so if i put one of those inlets on, a 4 branch manifold, induction kit and maybe ecu re-map what power do you reckon it would run? Quote Link to post Share on other sites
The_Notorious_C_A_T Posted January 18, 2010 Share Posted January 18, 2010 I assume when people run bike carbs they remove all the emulsion tubes or that kind of junk that comes with carbs? Quote Link to post Share on other sites
Asad Posted January 18, 2010 Share Posted January 18, 2010 possibly 90-110 mark, if the engine itself is healthy etc etcYup everything is stripped from them ^^ Quote Link to post Share on other sites
kane Posted January 18, 2010 Author Share Posted January 18, 2010 yeah all the parts do sound pritty expensive but seems nobody has done it makes me want to do it more now. lol. Quote Link to post Share on other sites
Jozinobi Posted January 18, 2010 Share Posted January 18, 2010 I'd sell my unfinished prototypes...Best 2 mani's you can buy Joz Quote Link to post Share on other sites
SiCaln Posted January 18, 2010 Share Posted January 18, 2010 wondered what u were gonna do with those man, thought it had gone quiet on that front lately Quote Link to post Share on other sites
Asad Posted January 18, 2010 Share Posted January 18, 2010 Just hit me, you asked about carbs not ITBS......as far as im aware carbs are a totally diff story Quote Link to post Share on other sites
The_Notorious_C_A_T Posted January 18, 2010 Share Posted January 18, 2010 Just hit me, you asked about carbs not ITBS......as far as im aware carbs are a totally diff story same principle if you're planning on keeping it injection.Although I am unsure on where the injectors are in these engines, the head or inlet. But still same principle, just if it's in inlet, need to make the new inlet with ports for them etc etc.If you plan on junking injection, would need to drop fuel pressure, and also get some spark only management of some form as the carbs will do the fueling.

Asad Posted January 18, 2010 Share Posted January 18, 2010 FE and FTE share the same head ^ the itb part of it is easy its the rest of the bits which cause all the ball ache Quote Link to post Share on other sites
kane Posted January 19, 2010 Author Share Posted January 19, 2010 I'd sell my unfinished prototypes...Best 2 mani's you can buy Jozhow much would you want for that lot and what carbs are they. Quote Link to post Share on other sites
Mack Posted August 8, 2016 Share Posted August 8, 2016 Sorry to butt in but would like to re ignite this thread, have been thinking of running carbs instead of spending money on expensive Ecu's. Was thinking to try mate that Corolla 4 branch with a 44 mm su carb, using a different fuel pump or fuel pressure regulator but would like ideas of what to do about ignition timing, would a distributor from a 3e engine fit on to 4e. It is possible as the grass track guys do it with k11s using k10 distributor (which I might also have a look at) anyway any ideas would be appreciated if I get round to it I'll post it up. Peace.

Sudden Posted August 12, 2016 Share Posted August 12, 2016 (edited) The "4e-f" (carburetted 4e) distributor has weights on the shaft like a traditional carb motor, with a vacuum advance and a built in igniter setup with the coil... Its basically an efi distributor but with mechanical advance instead of ecu controlled timing. The 2 pin distributor plug is the same, and the only one necessary. Bike carbs are more expensive and tedious than efi.I ran mikuni bs36 (yamaha fj1100) bike carbs on my 4e-f motor for a while, mated perfectly to a cut tubular intake manifold. Was part one of my experiment to prove the efficiency capabilities of constant velocity slides with individual throttles. But the needle that meters the fuel worr into the emulsion tubes causing them to run like garbage aftet a time, and the cost of replacement parts for the carbs came to over 80usd for each slide, and over $1000usd for a set of new/refurbished carbs. I Purchased 04 yamaha r6 itbs with injectors, tps, map sensor and harness for $19 usd. Fuel injection, retaining the constant velocity slide application to continue my project. IG @c.n.a.b. for picture documentation and any questions. Edited August 12, 2016 by Sudden Quote Link to post Share on other sites
Jamesreeveep91 Posted October 23, 2016 Share Posted October 23, 2016 Rights guys i have a 4efe and am wanting to take on changing it from efi to weber twin 40's what will i need? Also where can i but a 4efe 4 branch? Quote Link to post Share on other sites
Calum122 Posted October 23, 2016 Share Posted October 23, 2016 Why? There is nothing but performance and economy loss from switching from EFI to carbs? Quote Link to post Share on other sites
Pete_A Posted October 23, 2016 Share Posted October 23, 2016 A little unfair, theres not much better than the sound of even just a twin choke carb suckung in air through both holes and watching the petrol gauge sink as the tarmac flys by! Quote Link to post Share on other sites
Ollieh17 Posted October 23, 2016 Share Posted October 23, 2016 Agree, it's something different, adds an edge and sounds cool! Quote Link to post Share on other sites

StuDoc 72 Posted October 24, 2016 Share Posted October 24, 2016 There's a reason this has taken so long for someone to do. The build/running costs far outweigh the gains/noise. I wouldn't waste much more brain power on it. Quote Link to post Share on other sites
Jamesreeveep91 Posted October 30, 2016 Share Posted October 30, 2016 Because its different and sounds awesome its like bike carbs people've done that but not twin 40's yet Quote Link to post Share on other sites
