another old itb question

[Finny]

right...i have recently been adding bits to the car (handling wise) and now starting to think about tuning the engine.

Now i know the cost of boddies is ridiculous etc but if i was to buy these http://atpowershop.co.uk/catalog/renault-throttle-bodies-assembly-direct-head-p-91.html what exactly would i need after to complete the job? and roughly how much would it cost? if its ridiculous i will probably just go down the cams route with matched inlets etc etc..

cheers,
Dan

This kit is better, more complete, and the bodies themselves (made by jenvey) are a lot nicer to work with

Fully fitted and mapped, these are are ~£2800 from me for reference

what would you charge on some 428 cams set up with a map?

 

[Dan519]

I wouldn't use 428s for a start. Rubbish

There's a thread in my traders section about cams packages, but you'll have to pay your membership to see that

Why is the preference for DTH kits these days?

Is it just easier to manufacture/fit?

 

[Finny]

yeah il get round to it next week its well overdue this year for some reason

DTH means direct to head so there's no need for an inlet manifold. Anything easier for air to get in is a big yes

more engine specific with regard to lengths and injector position so there's a small performance advantage, they are cheaper overall, and in the case of the ones I posted, easier to fit. The generic Jenvey SF kit is fine, always works, but there's a LOT of small bolts and screws, nuts and washers, and a complicated linkage.

Is there any way of retaining the factory bonnet catch mechanism with this kit? Everyone one i see has all that removed and has bonnet pins fitted which i don't like.

 

[Silent_Scone]

Can be done retaining the catch, but without measuring it'd restrict the size of the filter you'd be able to use. Function over form.

they're done like that because it's the best way. Shortening the induction length kills off torque. Mine's so long I've only just resisted cutting holes in the bonnet inner skin for the filter to have more room. Man up
