Matt the Womble Posted January 22, 2022 Share Posted January 22, 2022 I've got a 2007 k series 1.8, 140 BHP, I was just wondering if anyone knows how much it costs to get jenvey throttle bodies fitted, ball park figure is fine and also if it's worth it or not ?? Ta ever so ! Link to comment Share on other sites More sharing options...
David Brown Posted January 22, 2022 Share Posted January 22, 2022 Have a look at DVA's site. Jenvey's are just the start! You'd need Emerald and airbox, at least but wasted without cams, verniers and new exhaust. Link to comment Share on other sites More sharing options...
oilyhands Posted January 22, 2022 Share Posted January 22, 2022 This^^, without trading up the cams, results will be disappointing for the outlay. As a guide.. Jenveys are around £730, Airbox kit £599, ECU £715, adaptor £159, then there is fitting of the TBs, airbox and ECU and calibration of the ECU. Cams are £595, Verniers £268, then there is fitting of the cams and verniers and cam timing. it's a slippery slope.Oily Link to comment Share on other sites More sharing options...

Area Representative Nick Bassett Posted January 24, 2022 Area Representative Share Posted January 24, 2022 ... and if you haven't got forged pistons, with all the aforementioned mods, you'll be needing a set of those too! Link to comment Share on other sites More sharing options...
pkw2704 Posted January 24, 2022 Share Posted January 24, 2022 if he has 140 already has he not got the cams in ? supersport? I fancy this route eventually and am running a 1.8K with 140,just fitted the 421 exhaust system to free it up a bit.I would be hoping for 160bhp with this and throttle bodies,would this be so? Do you have to do the pistons if your not bouncing of the limiter all the time,could it be set up to give better pull lower down the rev range?

oilyhands Posted January 24, 2022 Share Posted January 24, 2022 The cams in the 140 are very tame compared to the supersport cams with a lot less duration. You may get to 160BHP but it's a pricey way to do it, probably around £2800-£3200 by the time the TBs and ECU are installed , cams timed and ECU mapped. If you going to spend that much, cough up a little more for a decent set of cams and you would have a far more exciting engine.On a 140, a decent set of cams, properly timed, a match of the inlet manifold to the head and a Kmaps remap would probably get you to around a true 145-150. The '140' engines are the same as the Trophy 135 which makes around 130 in the MGF and Elise both of which have a superior exhaust manifold. They don't make 140BHP.Oily Link to comment Share on other sites More sharing options...
pkw2704 Posted January 24, 2022 Share Posted January 24, 2022 What do you reckon my 140 with the K maps and 421 full system is at now then ,approximately? Link to comment Share on other sites More sharing options...
oilyhands Posted January 24, 2022 Share Posted January 24, 2022 My guess would be a true 145BHP , a touch more if you are lucky.Oily Link to comment Share on other sites More sharing options...
