110bhp out of a VTR

kent 285 cam=£200
uprated valve spring=£80
adjustable pulley=£90


and then id stick on a bike carb set up which if you buy most of it yourself can be had and put together for under £400


asuming the above cant all be found cheaper 2nd hand or as part of a deal that all comes to £1240 in total


and once its all on a running ya will be pushing around 140bhp(might not seem much) but you will have a highly modded engine and car that will go like stink and sound fucking awesome




other alternative is to spend around 1k maybe more on getting a 16v dropped in it and them camming that which will cost around about the same but will need a remap to get the best out of the cam which will produce 150bhp


and to 110mph my money would be on a carb and cammed 8v cos the torque from the 8v will be just stupid


at high speeds then yeah the 16v will win but who cares its all about the bottom end for me



its mainly down to what YOU want your car for and what you want from it


bhp figures win arguments
torque wins races

I've got the 98bhp silver top leeds.

Won't it need a remap with the cams?

I'm just trying to weigh up the options really. If I spend that much on a VTS i'd be looking at 6.5-6 seconds to 60 and around 155-160bhp?

Has anyone on the board actually done those mods leeds? I'm interested to here their results.

[leeds106]

not yet but im about to hehe


ive got the carb set up i just need to put together an inlet manifold and then put them on and see how it goes with the 266 cam in it


at the moment i can pretty much keep with most 16v's till around 80 when they creep and i meen creep away


with the carbs and the 266cam i recon ill be a touch quicker till 100 tbh


once i get a 285 in it and set it up on carbs i recon ill be raping them hehe

[leeds106]

with a 285 in your engine without carbs you will need to remap it asame as i will if i dont run bike carbs and fit a 285



all you will need is

285 cam
uprated valve springs
adjustable pulley


fit it all then take it to nearest tuners for a RR set up

with manifold,exhaust etc you should on injection be making around 130bhp and plenty of torque to keep you happy

[leeds106]

here ya go the very 1st time a 98bhp vtr engine has been ran on bike carbs all caught on vid

it was only a mock up though as i used a standard plastic inlet to make up an inlet so it was never intended for driving purposes
only bad thing is noone makes inlets for the 98bhp engine as the post spacing are different to the 90bhp engines
hence why i can just order an inlet i have to make one up

[vtrlad]

Thats does sound pretty nice.

Are you running a silver top in your quiksilver then?

[leeds106]

yeah had it fitted about 18months ago as it was low milage(26k) came with 4-1 gmc manifold and unlocked ecu and cost me a damn sight less than fitting a 16v


never looked back tbh

Totally agree, Repped

[vtrlad]

I thought the 1.4 alloy block in the Quiksilver could easily out perform a VTR tuned?

[leeds106]

no cos at the end of the day there is no replacement for displacement


my and fuzzy orange ran engine with the same mods

mine 1.6 8v his 1.4 8v and from the line the differences were very noticeable


side by side at say 40 in 3rd and gun it the 1.6 8v was still quicker but the extra weight of the vtr cast block showed a bit more


one thing i found going from a 1.4 to a 1.6 was just how much drivable it is at slow speeds


i can now drive at 40mph in 5th running at 2000rpm and put foot down and the car just goes


before id have been dropping to 3rd or soemthing lol

[vtrlad]

Do you think it'd be a good idea to RR my car first?

If it's not hitting 98bhp now, whats the point in modding it right?

[leeds106]

dont worry about what bhp it is making
so long as it feels quick and your happy with how it drives then thats all that matters


figures meen nothing its how it goes on the road that really matters

[vtrlad]

Why do you recommend a 4-1 mani over a 4-2-1?

[leeds106]

no scientific reason tbh but everyone i know runs a 4-2-1 manifold and mine quicker so i can only assume its helped or certainly not hindered it in anyway tbh

[AlexR]

dunno how many times i've been into it, a vts engine will always be better than a vtr engine when modded for the same max power, a 16v has a wider spread of power because of the design. who do all manufacturers use 16v engines now?

cos they bought the 16v badges cheap on bulk order from halfords?

[AlexR]

Of course, how silly of me

[pjm300]

simple explanation for everything

[leeds106]

its not quite the point of this thread though is it


he just basically wants info on which is worth him doing


and cost wise i know what id do but then again ive done the whole spending a fortune on cars years ago so im not less willing to do it as much


otherwise id be running a mad bodied 16v engine

Why do people go for engine swaps so often then?

cos its the cheapest way to get from vtr to vts pace.
