Which would get the most respect at a show? -
A VTS with wild cams & tb's
or a VTS turbo running 250bhp+
A VTS with wild cams & tb's

both are good performance conversions if done correctly. Never base a performance modification on whether someone will release bodily fluids over your car in sheer exitement. Otherwse you end up with an engine hat looks nice but doesnt meet its full potential, a bodykit for your engine so to speak...
|

dont get me wrong, Love the Saxo's.
Just wouldnt mind a newer car Plus, I could cam my VTS and take absolutely everything out of it.. ...or could just buy something quicker and keep my rear seats etc. |

| think the Clios will depreciate like a beast too. |

|
okay Ryan do that bud please
Wish I got to hear gods 106 tbh.. Ive heard vtr130s when it was on 708s, didnt sound that impressive, but bare in mind, was on an industrial estate with shed loads of other cars (such as impreza's) ragging it. and Leeroy, that pic doesnt sway me, phase ones look like they're tired and unhappy. |
| josh has the same TBS as i do, theyre very quiet because of the airbox, but should give a better life to the engine |
|
They are both sexy as hell sorry man. But the blue one wins sitting on the
182 Trophy style rims. Ive been told that if the trumpets are left open, then debris that enter the trumpets can damage the valves and shite! Heard horror stories of meshed trumpets sucking the mesh into the engine! So if anyone fits TBs, an air box is soo need if thats the case. |
|
Very mild cams i think
Not much higher left then the standard ones |
|
tb'd a clio Ryan
At least the inlet is on the front, better rammage of air |
|
Man I cant beleive so many of you dont like the Mk1 Clio 172! Its pretty damn
nice imo. And in the yellow Anyways, for 180bhp out of the 1.6 16v lump Im guessing you need all new pistons and valves? Bottom end rebuild? How much would all that set you back inc the cams, TBs, exhaust system, ECU etc etc? |
|
Phoock man thats hurting my eyes. Ive always been looking at a spec like:
Full Pugsport + Supersprint Manifold Piper 285 cams Port/Polished/Gas flowed Head Jenvey 42mm ITBs Lightened and Balanced bottom end <<< required? OMEX or Emerald Management Oil Cooler + Catch Tank Lightened and Balanced Flywheel Lightened and Balanced Crank <<< dont even know what that does/worth it |
|
Nah not aiming for 180bhp mate, anything around 168bhp+ would be a result,
more the driveability though im interested in. Dont think I would want wilder cams than 708s/piper 285s. Its actually a Pugsport centre with Magnex backbox I have fitted. If I went for a full Pugsport I would have it cut to peices and hidden as I hate the look of it! So from what your saying a lightened/balanced bottom end and crank are pointless with this type of setup? Whats your advise on TBs for that kind of setup, Ive only just found out they have different diameter bodies. You mentioned 40mm being restrictive? Would 45mm be excessive? |

id personally go TBs.
booost is ghey ![]() Tbs on TU engines dont give huge power unlike on redtop engines for example. But give good throttle response, improve all over torque and sound the bollocks. the only thing a turbo does is go broom tish! which makes the macdonalds crew beat off over. lol turbos may produce more bhp but a well driven NA engine will piss on a tubby round a track |

Yeh i am seriously considering buying one of his boxes of him, if i can find a bit of spare cash
Its a Quaife 2.538, 1.765, 1.421, 1.190, 1.043 close ratio gear cluster built in to a late type Saxo MA box along with a Quaife ATB limited slip differential with a standard VTS final drive. Can you explain tht to me?? |

| This with your 9000rpm rev limit? |
|
" fancy air filter " that sounds good power gains is hardly nothing
|
|
tbh i couldnt give a shit as a 1.6 engine is bollox and if i was building a show car id have it for a while.....i dont intend to run a 1.6 for longer than i have to.
If i was going to show a car it would have a 2.0 Twin Turbo engine. No ifs/Buts. It would have a silly sized turbo with a smaller quick spooling turbo. And it would be Japanese and RWD. Its my opinion so nerrrrrrr |
|
Expand lol ???
Well i see cars that get taken to a garage, someone spends about 2 grand, and they come out with a Mahoosive bhp figure.....and run fine. Yet to get any life from a 1.6 you've gotta tweak tweak tweak. Its pap imo. |
|
Saying that, if you had a bonnet scoop to inlet air and a proper feed like JP saxo then the air would be forced sort've as it direct to the inlet
My ideal car would be 2.5 sequential Twin turbo with AWD |
|
Saying that having 700bhp of pure power inder your right foot with turbos that can take your head off at 9k rpm in every gear would make a huge difference from a 130odd bhp saxo
|
|
JC - jap crap.
Saxo forum - generally discuss tuning saxo engines for some un known reason. BHP doesnt increase your cock size. |
|
Dont be a gay just because i dont want a 1.6 all my life....no need to be a cock is there.
But it shrivles you'res..........when the only thing you see on a 1/4 mile is the back of a boosted Jap monster.... 1.6's are good, but my point is id get a better engine to start with if i was going to make a show car. I hear alot of jap owners who have and have had saxos say they havn't driven a more fun car. But i like to feel the power of boost kicking in on an engine pushing over 400bhp... than boost on a 200bhp car. Mind a VTR id say 160. Which a saxo isn't going to do..... |

A turbo car once well set up can be as fast if not faster than a n/a car, but what you find is that most cars are built to a budget and n/a people can and do spend more on suspension which is where most of your time is made. £3k on suspension is better than £3k on engine parts when you are building a circuit car.
|

Throttle bodies dont work by a forced air though, they take what air they need. the only problem you have is on TU engines the inelt valve is at the back of the head, so the air drawn in is hot, hotter inlet gasses are not so good for cimbustion. Jost doesnt have a scoop, he has an airbox with air being fed from the the slam pannel.
The maxi tb set up on the 106 has an underbonnet skin feeding the tbs which are in a 3/4 style airbox the bonnet itself being the lid to give cold ambient air to the bodies themselvess. and sicne when was this an ideal car thread??? |
|
I know but if they can be force fed clean, cold air directly would that be the same as turbo's inlets?
Maxi set up is interesting cheers for the info. How do BICS run? |
|
Yea, i know. The fastest 0-60 is a vauxhall.....
But BHP/£ seems to be best on the Jap market. And im fed up of having a 1.6 that, yes is ace around corners but i wanna feel my face mashed towards my ears tbh |

With any setup its about useable power. 700bhp is no good if you can't accelerate with your foot to the floor as you get massive wheelspin. Throttlebodies offer a far quicker throttle response over normal inlet systems and turbo/supercharger setups and are easier to drive at the limit. But take any engine, you should look at getting the most power out of it, Dry sumps, smaller alternators, small flywheels & clutches, catch tanks, straight cut gears, lightweight internals all help to remove parasitic losses and get the maximum potential out of what you have.. |

Vtec is not about big power. It was designed to enable a car to have good fuel consumption even though it had an aggressive cam profile for performance, so a jekyl/hyde engine was created. To tune the cars to race spec you will always find the vtec is the first thing to bin. A similar pug engine with a fast road cam will be similar power though it will be harder to drive at slow speeds and fuel consumption will suck in comparison
|
|
off topic, you seen sybez is thinking about going back to single TB with the charger?
|
|
BICS?
theres no such thing, BIC is a person. He has Pugsport DTH throttle bodies as far as im aware, in a modified (206 irc) longmans airbox, its got a pannel filter to clean the air, and the airbox should theoreticaly help with the ambient temperature. A Turbo is ALOT of pressure the air is compressed to, you wouldnt get anythig near this from TBs. For a start a trumpet couldnt produce anywhere near enough ram effect to compress it. |
|
Throttle bodies are all about getting the maximum air to each cylinder. With a single body one cylinder might run lean and another rich due to the poor designed airflow inside the inlet manifold. Individual tb's can be tuned to allow the correct air to go to each cylinder.
With a turbo engine the air is far denser with oxygen and the benefit of throttlebodies is negated as air is pushed into the engine. He will probably benefit from a larger single unit for engine simplicity and power... |
|
Vtecs are the engine alot of fast road users have as the engine of choice was my main comment. The Vtec engine is a masterpiece in itself. It was because Ste was saying about HUge power and haveing a jap car, which as you just said Vtec isnt about that
Personally would prefer not to junk the vtec and keep its nature and just run some bodies on it, seen a few very nice Tegs like this that were superbly set up. |
| The average jap cars are nothing great to be honest. |



|
I like cars, not just a car because its from a certain part of the world.
|
|
Ryan -
not really. The 309 has a Rallycross kevlar carbon body, spaceframe chassis, honda s2000 engine, transmittion and suspension, RWD and you get the idea. Imagine a 750kg s2000 and you get the idea of performance... |

|
The JC is a tounge in cheek joke dude dont take it so serious.
Personally i am a skyline fan, but thats not because of the engines themselves, but the handling system on them, the fact they were effecitley banned from racing in certain race series speaks for itself. Im just a bit bored of the whole people beating off over anything thats JC tbh. |

|
Just one thought that's popped into mind, if you can't decide wether you want iTB's or a Turbocharger, have both
Oh and that s15 is god damn gorgeous! |
|
It seems a few people with the SR20 engines use iTB's as well as a turbo. in my opinion you simply get teh best of both worlds.
And the noise, OH YEAH! You mean locating them in the engine bay? Or actually finding the parts? |
|
unfortunately it was found for the saxo engine, that running anything greater than 40mm t/b's let in far too much air even on very slight throttle.
of course it could probably be achieved by using smaller diameter bodies, but then you've wasted 500 quid on the bodies, then linkage, then manifold, then plenum. so its over a grand which could easily be spent on a better turbo/pistons/rods. |
