Hi All I Need Help Again

[carisma02uk]

ok i have decided to sort out my engeine so i have been to check out a pipercross viper forced air indouction kit.

as they dont make one specificaly for my car and the only specific features to each car is the fixture pipe i was wondering can i just buy a one for a 1.3yaris and fit it to my 1.3 rolla E10 with the use of thr reducers form my universal indouction kit.

ok more to come...

i want a zaust system for may car i need as much bhp as possible,

do i got for a,

new manifold if so what kind:

down pipe: what make.

and who to get it i will be emailing powerflow soon.

CAN MY ECU BE TUNED OR DO I JUST HAVE TO KEEP HAVING A CARB TUNE EVERY TWO MONTHS!!!!!

HELP ME

no offence mate but casing bhp in a 1.3 is a bit pointless.yes you could probly fit induction and manifold with full system but gains will be a few bhp for few hundred pound you spend.and all it will mainly do is anoye your neighbours ;)

if you want big bhp do an engine conversion if your after a bit more roar the an exaust and induction kit will satisfy.as for carbs thats just carbs,go injection.

hope i helped and a didnt mean to p*ss on your chips

no probs mate dont know bout the swap yet tho.

You don't say what age of Corolla you have but I do see that you say you have a Carburettor engined model, so it naturally won't be a recent model. Also if an older carburettored model there won't be an ECU.

If you want to do a bit of 'cheep' performance tuning (your first attempt perhaps) then an older (carb engined car) is ideal as there is nothing complicated like an ECU.

What I would do firstly is see if there is an alternative carburettor conversion kit for your car. Such as a Weber conversion kit, which will consit of all necessary linkage and (if necessary) a replacement inlet manifold or mounting/conversion plate. The weber carb will probabley be a 32/34 DMTL or 34 DMTR Twin-Choke. The whole kit should be less than £240. Also you may need to buy an Air Filter kit such as a K&N (Which would be the one I would recommend for a Perfomance carb set up), the same firm which now makes 57i kits for 'modern' injection systems.

Another aftermarket performance carburettor was the 'Nikki', these were also sold as a complete conversion kit, (which was marketed alot in the 1980's) these where originally rediculed when first realised but nowadays are sometimes sort after buy 'Old School tuners'. They are no longer marketed in Europe now but do sometime appear on eBay in 'boxed and unused condition'. They were Japanese in manufacturer and yes, I want one for another project I will be doing in the near future .

I don't really recommend you buying a second hand perfomance/twin choke carb of a mate of a mate etc. As you may find its worn or not 'Jetted correctly.

Also referring back to Weber you may get some 'Fantasist' at a local 'cruse' or car show telling you to stick a "pair of 'Weber '45 DCOE's' on it". Yes you could but a set up like that would cost you at least £800 and knock you fuel consumption down to about 10mpg... and eventually burn your valves out!

If you do decide to fit a 'sensible' peformance carb your fuel consumption will drop a little (3-5mpg) and dont forget to check with your insurrance company as it is a 'mechanical modification'!

Give somewhere like demon tweeks a ring to see if a carb kit is available-

Sorry twincam, but I don't think suggesting this guy spends hundreds of pounds on a carbuerttor is a good idea.

The only reason for uprating the carb, would be because the current one cannot handle the fuelling that the engine requires.

From a 1.3, with an exhaust and air filter, he's going to see a gain of maybe 5BHP. What is the point in spending money on a carb?

Maybe if he modified the head, and put in a hotter camshaft, uprated pistons etc etc then there would be a need for more fuelling, but that would be pointless.

As andy said, the only sensible option here is an engine conversion as far as I can see.

Kidkoala, I was only trying to give the chap some basic advice. I was only advicing from what I have done myself with older cars.

I thought i'd start with what friends and I did back in the 80's with oldtimers (A35, Mini, Mark1 escort, Anglia, MGB, spitfire, midget, TR7, Viva and so on). Next post i'd do would have been advice on exhausts etc.

I was trying to keep it cheap as possible hence me telling him not to waste money on sidedraaft 45DCOE's and get a an 'updraft' instead.

I did think about camshaft etc. but didn't think he would like to pull is engine apart...just yet. Hence my advice for just going down the 'slapon/bolt on performance' goodies route (I know this is sometimes ridiculed but people have to start somewhere ).

Yes, granted, exhaust and filter are fine, but theres no point in "slapping" on a carb, that won't show ANY increase in performance, waste of money.

Take minis for example, you wouldn't slap twin carbs on a 998 unless it was highly tuned.

Well actually in 1987 we stuck a Weber 38 DTML (Think it was a '38) Updraft on a standard Mini 1000. We left the standard exhaust on (had to cut the manifold inlet bits off...took ages to hacksaw through to enable the Weber supplied inlet manifold to fit). The weber was given to us for nothing so we thought what the heck go for it and it did improve acceleration ...but not fuel consumption

Also one of the official 1960's 'tuning kits' for the 1950's A35 consisted of a pair of Twin 1.1/4inch SU Carbs to replace the single Zenith carb and a 3branch manifold and 'Peco' exhaust.

Probably because it wasn't tuned properly in the first place.

As if I would be guilty of such ...err ... mistakes oops
