Twin 40's ona 1.6 GSi engine...

[broody]

Can anyone enlighten me about this, i know nothing of twin 40's and would like some info, or any other info about what engines are good with twin 40's.
thanks

don't bother unless you are doing other mod's. mine gave me 8 bhp on a standard engine. get a head and cam first, i think there's a B+ head on ebay

[broody]

so probably a rebore, new pistons, cam, head, something along them lines.

[-Bruce-]

yeh that would work well!! are you going to do that neil? as ben said there is no real point in carbs on standard engine!!

bruce

[benji]

it starts getting pricey though. i've priced up a new bottom end at around ?600. that's just the bottom end, no head work or cams

[broody]

yeah broos3, getting my options ready at the moment, at the mo im going to get a gsi engine, strip it, as i said before, rebored, bigger pistons, head ported, cam aswell, and twin 40's or 45's.

Got about ?1000 to play with and going to make a sleeper, only thing im going to have is alloys for traction.

What im think of so far is
Nova - ?100
Engine - ?500
Alloys - ?100
Other bits- ?300

[-Bruce-]

sounds like you got a wee plan there neil!! sounds good as well. keep it looking standard though!!

bruce

[broody]

yeah bruce deffinately keeping it standard.

Will keep you posted with how it goes.

[benji]

your gonna need more than 500 unless you buy aready built engine and get a good deal. theres a group a 1600 engine forsale on here and a well modded 1400 with t40's for ?600

[broody]

yeah well the ?500 is a rough figure.
going to do alopt of it myself.

[benji]

new cam = ?170
B+ head = ?450
carbs = ?250 - ?800
bottom end = ?200+

good luck

[broody]

um, good point ben, maybe an xe then, about ?300 for xe, then shafts ect.

[epo]

whats happening with 2.0 8v mate

[Dpnova]

my cost currently stands me at 650 and i still have a few bits left to get

[broody]

dp can u pm me a rough guide of wat uve spent money on so i can get an idea

[burgo]

neil u can have a 2l 16v eco-tec off me for ?100 nice cheap lump for ya to drop in

[Stuart]

the "proper" rebuilds for 1.6's that ive seen are in the realms of ?7-800 JUST for the bottom end, then you have to get the head P+P (bigger valves etc) another ?300 minimum, if you get the valves done yourself and then port it yourself, but you need to know what your doing.

cam + parts like new followers, recon the hydraulic lifters, recomend new springs etc

+ rebuild costs like gaskets ?100ish

then the carbs anywhere from ?200 (needs rebulids) to ?500ish

?500 simply wont cover a proper "sleeper" rebuild for the engine.

you may get a "quick" car, but it wont really be a fast car, if you get my drift

[Philsutton]

for 1000 you could get a 2lt 16v, all mine cost if that

[Stuart]

its got to the stage now where its a novelty to find a NON 2.0L nova.

they are so damn tedious lol

[Philsutton]

but if you want a fast cheap car then it seems the logical thing to go for, twin carbs are gonna cost more than the engine.

here here

[Aragorn]

lol i'll be staying with the "small block crew" for a while yet too ;)

the 16v is in the garage just now getting the head rebuilt and after thats done i should have a nice quick small block powered nova :D

was in a 2.0 16v on 45's the other day and insanely quick is an understatement

[benji]

they are so damn tedious lol

that's why i'm sticking with a 1400

[broody]

i wanna stick with a 1.4/1.6 instead of 2ltr but want mods done to engine to make it quick for the engine size.

whats 1.6 16vs like for bhp and acceleration?

[benji]

1.6 16v is the best bet, lexmaul/mantzel/velos inletmanifold and a uni chip and you will have 130 bhp. and a 15 second 1/4

[epo]

personally the only reason am stickin with a 1.4 is as i cant aford a valver :cry:

otherwise i'd have one or at least a 1.8

[Jim]

We should start charging for duplicate posts, lol. This question comes up nearly every week.

If I've said it once, I've said it 387 times. Look at Dan's feature or Russ' rally car for a well modified 1.6 with twin carbs.

Your dreaming if you think your going to get it all done for ?1000. It cost me just under ?1000 for the bottom end work. Sourcing carbs can cost you up to a few hundred, the headwork will be another few hundred. Then theres little bits and pieces, like gaskets and other ancillaries.

Then, if you dont really know what your doing you'll have to get someone to build it up for you, and not just any garage, really, you want someone who has a good knowledge of twin carbs and setting them up. Then theres the rolling road session to really get the engine running at it's best.

You need to budget over double what you originally thought.

y are u taling of 1600 engines when u have a 2.0 8v?

[Gunzi]

don't bother unless you are doing other mod's. mine gave me 8 bhp on a standard engine.

See this link http://www.novaload.net/forums/article.php?t=63460

They rolling roaded a std GTE @ 100bhp then added Weber 4-'s rolling roaded at 116.3 bhp.
its at the bottom in the results section.
BUT it does go on to say that the results will vary from car to car.

read it yourself. that engine has a B+ head and a piper cam

[m.d.]

you can do it all for less than a grand if your mechanically minded that is.
ive spent so far 150
Quid on kent cam
150 quid on 2.1 bottom end with standard head
bout 300 quid on carbs
120 quid on the manifold
100 quid on exhaust manifold (16v made to fit 8v head)
60 quid on rebuilding the head after i ported and polished it
160 quid having the flywheel crank rods and pistons lightened and ballenced.
80 quid on vernier pully
and the rest was on shells rings and gaskets.

before i had done the better flowing head bottom end and 2.1 rebore i was getting 160 bhp. ive been told that 170 to 180 bhp is on the cards when the motor is put in the car again.

you will save cash if you do things yourself. such as porting and polishing the head. and building the motor itself.

[benji]

total of ?1120
