List Of Mods to do

[Beech36]

right i want performance mods. i thought it wud take me a while to do what i planned but funds are looking good so could have it all done in next 4 months. so need more suggestions. just baught enclosed air filter, buying an exhaust friday. 4-2-1 supersprint manifold waiting to be baught (may go for a 4-1 so i dont have to piss about moving oil filter back for MOT) and cams can be baught in next few months.
also going to buy either a 1.1 gearbox 1.4 furio gearbox or vts gearbox so need opinions on that. cheerz peeps

depends on what you want to use the car for everyday? weekend? track car? this will govern all your mods!

Fast economical road setup typically consists of the parts you've named although i've noticed your car is a VTR and im assuming its running on the standard 8v 1.6 engine! Like all modifying it's all about power vs weight! so lose the pounds and you'll see quickier acceleration times, bolt in a 1.1 box and you'll also improve acceleration.

Currently my VTS runs on the standard VTS gearbox and tbh the gearbox seems fine, i think the 1.4s and VTR have the same gear set however the crown on a VTR gives a slightly lower ratio improving acceleration - although correct me if im wrong might have that the wrong way can't remember! but if your using the car everyday you're never going to drive at over 100mph all the time so acceleration is the route you'll want to take up

also most peeps will suggest starting with the VTS engine although you may have insurance issues, the VTS engine is a good base to start with. Regarding modifying engines is all about reducing pumping losses and improving work output as this lil PV graph shows:

All engine modifying is governed by this, the bigger the work area the more work output/power you'll get from your engine. Like i said if you want more power you must reduce your pumping losses for example, by putting on a 4-2-1 you'll improve exhaust gas flow reducing back pressure and thus reducing a pumping loss in the exhaust stage (points 4 to 1 on graph)

In my opinion one of the crucial things to reduce is frictional losses, this includes inertia forces created by rotational parts for example the flywheel, a very reliable part of the engine (as i've rarely come across faulty one's) but OEM flywheels are heavy producing high inertia forces, lighten the flywheel and you'll notice you'll get an improved acceleration (we're not talking massively but it all adds up), crankshaft, ligthening, strengthening and rebalancing the crankshaft and you'll notice you can push the engine harder and improve throttle response as less energy is required to move it.

If you reduce these internal frictional losses you'll notice good performance increases however its all about budget and what you can and can't do! Obviously breathing mods are the first stages the majority of people take when it comes to modifying as their cheap and easy to do yourself. By even little things like having the correct oil viscosity for your engine, ensuring the engine has good cooling supply as you can push the engine harder without it overheating!

You can take this further internally into the engine combustion chamber design, valve ports and piston configurations! This is where the big performances are gained! How do you think F1 engines that run on naturally aspirated technology can achieve 700-800bhp! One critical area is the tolerance between the cylinder wall and piston the tighter the tolerance gap the more bang you'll get for your buck as more energy is used to push the piston down the cylinder rather than wasted in sound and heat energy or worse escaping around the piston rings to the sump! I won;t go into too much detail about this as im sure you know a fair abit and im boring you already lol!

All im really saying if you want a good performing engine you must consider reducing pumping losses! Hope this helps!

Is go for a vts box over a 1.1 pretty much the same but have a bigger diff, the vtr box is the slowest accelerating box

And what are you on about moving the oil filter for mot times?? You don't have to move it lol
