"Injecting" more power? - Page 2

Blackie · 26-09-10, 11:29 PM

Friends with a stick? I like a bit more finesse than that tbh, but good to know about the 8v.

Which engine is more tuneable though, 8v or 16v?

Both tunable but 16V more expensive thanks to extra valves involved and needs revving to get the best performance from it.
Head work on the 8V tends to release most noticable power, changing cam will get more power but if it's like the 2.0 I had in my old passat it will then need revving more as the torque curve is pushed further up the rev range.
Just chuck the 4 pot and fit a 2.3 5 pot instead, job sorted

Now that would involve a lot more work and parts. I'd defo need a gearbox for that engine, and god knows what else!?!

Why damage 4 pot engined car with 5 pot engine?

In absolute terms, 16v, of course. Racers get out from that engine more than 100 bhp/litre. Nut in reality - what's that "tuning mania"?! What's the reason to do something with daily car's engine to get a few horses more? Ok, that will probably add a couple of miles to top speed - but to enjoy that without fine u have to go to germany anyway. Or to say to other [if u would choose ABK] ABK engined B4 owner "my ABK has 5 horses more than yours, I pone u, mwahaha!"?

There is no practical reason to do anything to such engine, except, for example, if u have it disassembled and u have spare time, so u can polish manifold etc. Engine as it is in stock is built to be cheap enough [so polish can help someting a bit], to don't steal sales from more expensive engines [as in case of 1.8 20vt] and also to be driveable. And that's all. Only tuning, that is worth big investments is turbocharging that engine - if u know what u are doing or if it's done by someone who does know what to do.
Ok, in case of EFI fueled engines I dunno about so called "performance chips" - if it's worth, then not because of few horses, but for better throttle response - if it helps in that way.

The point is irrelevant to be honest, you could open a can of worms and say,why do anything to a car this old? why do anything to a car other than drive it, service and basic maintainance?

Why fit a better sound system, bigger/nicer wheels, lower suspension, different seats. . . . . .

I could go on, but the thing is, and to get back to the main part of the topic, I asked a question, I want an answer not a debate of the reasons why......

you already have the answer...

the injectors probably will fit...but without more air it is pointless

Ok, thank you folks, that is the answer I was after, the air part will be easy but thank you.

i have a 1.3 16v dihatsu charade.....

.......85 bhp!...

years ago i priced pushing it to the edge!

larger cc injectors, billet grind cam, ram-pod induction kit, aftermarket ecu, port & polish, brakes, lowering, blah, blah, ...mostly only avaliable from a company in australia.

result...

pointless...

priced a charade de'tomaso....(130 bhp)

.....and..

it cost less... and you got recaros thrown in.

i found that there are many companies out there selling 'promise' 'hope' of getting more out of your car.. but they also get more out of your wallet than if you just buy a faster car.

the charade...still has 85 bhp

CHRIST! What part of "I didn't ask for a debate" do you folk have a problem with? What does the rhyme or reason matter?

What may be rubbish to one man is another mans gold! Or, what may be pointless to one person, isn't Yo another.

Please end of conversation!!

i dont think there has been a debate

i think we are trying to give you advice that you dont want to hear

i was trying to help

get some injectors and try them. as part of a bigger project.

you sound like you know that it will be a bigger project if you have already thought of a new camshaft.
