Guys, Just had Tullet Manifold and 200 C down pipe added to my Larini. I keep hearing that I must get a 2.4 Inlet Manifold I know nothing about the internal workings of cars - so what does it do, what will I get if I have one and how much should I be looking to pay? Please feel free to post jibes regards my inability to understand what the hell those 3 peddles are connected to in the footwell

I have one, never fitted with ECU bracket and all the other stuff needed. Was going to fit it once I've finished porting my cylinder head, but as thats been a year in the making and is only half finished, it could be 2015 before it gets used Make me an offer and I might let it go

[Kdan]

im also interested in this, not too sure where i can get hold of one though are these a pain to fit? i would most probably take it to be fitted at BOT depending on how big of a job it is

To buy from courtney CLICK

in laymans terms, it allows more air in to the engine.. search on here and u will find some who recently fitted it.. "the best mod for in its price range" so ive read.. great pull in high rev through out 3rd and 4th gear..

Also you tube it, (vx220 2.4l inlet manifold) you will see a vid of some one who has fitted it.

something ill be looking to get when i have the money..

P.S post some vids of the Tullett if you can.. im looking to get the full system too..

cheers!

In all honesty I wouldn't bother. Ruins the torque/power curve of the engine - worst modification I did.

Did you get your car remapped for it? I gained torque and a decent amount of additional power throughout the range but that was after TMS had done a _lot_ of remapping to suit it and the other mods. MartinS had a similar experience.

In isolation, I agree, the 2.4 inlet isn't worth it.

I've read many things about mapping with the 2.4 inlet manifold.
The people who seem to have had the problems with it losing torque and not doing much are the people who have had a stage 1 map of sorts to correct the torque curve on the standard engine.
People who either have a standard un-mapped car or have had the car mapped specifically for the 2.4 inlet have reported good gains.

Something I'm going to need to think about with mine, because I have a stage 1 TMS map, and when mine is done it'll need remapped due to the new cat-back exhaust and the pre-cat getting removed as well. More money!

I was one of the 1st to get the manifold - I never did get it mapped because of all the troubles others had trying.

Having dyno'd the car several times, the standard map was actually not bad (albeit slightly rich) - Tweaking the std map wouldn't gain that much. The standard map is auto learning and adjust quite well to modifications. The reason the stage 1 mapped cars struggle is because certain tuners disable the auto learning function in the ecu. Any future modifications to the car and the ecu won't adjust which basically make the car run either really rich/lean.

I have posted some videos of my car on track before and after fitting a compete Chris Tullet exhaust in this thread

Post 1 is standard car

Posts 19 and 22 is with exhaust (including manifold) and Hofmann's spec Nitrons

That would explain why people were having issues.
Do you know who the "certain tuners" were? (PM if you don't want to name&shame)

Courtenay seem to be getting pretty consistent results now mapping the 2.4 manifold (high 160 low 170 bhp) things have moved on since the first manifolds were fitted. Torque is lost over the standard manifold at certain Revs but gained at others its your choice.

But we've since established that with the 2.4 inlet and other mods fitted, that this takes things beyond the ECU's capability to automatically adjust it's fuelling tables. Mark Verboom's mate in the Netherlands seems to be having a lot of success with his customised ECU firmware and extended adjustment tables for the self-learning/tuning.

More money!

a full ecu is available from me already map from courtnay with a very nice graph
and either i am crazy but this was a very good mod on my car but prefer the itb's with all the goodies
everytime i go for a drive those itb's drive me crazy good mod but bloody xpensive ..another 2k of goodies this years are going on it

[Exmantaa]

Yeah, The custom remapped 2,4's seem to run pretty well here, but sofar I've not seen dyno results from this remap. (Preferably standard vs 2,4 vs remapped 2,4 on the same dyno.) That remap is a bit expensive though...

my dyno is on this site somewhere
shall i upload the dyno again


ps you canno't run a vx on a £5.00

Yeah, I've been keeping an eye on his thread over on z22se. Hope he get's it over here soon!

My aim is to dyno before and after the dutch remap. (to finally get some clarity)

@ the rest, here's the throttle body response fix the same guy that built the remap made:


It's now included in the remap 2.0

An oldie but a goodie of my cars evolution



Lowest to highest:-

Standard

Stage 2+ (Full Milltek system and cat, ITG, TMS Stage2+ map)

Stage Whatever (Full Milltek system and cat, ITG, 2.4 inlet, TMS 4-1 manifold, mild headwork on inlet tracts, lots of TMS mapping)

SC Stage 2 (Standard pulley, 2.5" Piper, same head)

[Crazyfrog (Fab)]

i believe it was this one
with the 2.4 added
