need more bhp on my 1.6 vtr 8v sitting at 120bhp atm

[jasonmayall]

No need to replace the rockers at this stage.
Better springs would benefit, but again not at this stage.
Go for a performance cam (upgrade your valve springs at this stage if you want).
However, if you plan on going turbo, the cam will be irrelevant.

If your really going to turbo it, then leave it alone for now. Have a good search through some 8 valve turbo builds and concentrate on collecting all the parts you'll need.
But for now spending money on handling and braking would be your best bet, to make full use of the power you have.

Fitting a turbo is very worthwhile on the vtr, as if it pops you can pick up another engine for peanuts and between 150-200bhp is quite achievable.
But make sure you know what your getting yourself into and work out the costs involved.
Parts for boosting can be had relatively cheaply if you get get good used gear.

A cam would be the next step

Silver tops came in 90 and 98 form

i thought it was black top 90 and silver top 98

No

Late mk1's and early mk2's have a 90bhp silver top, any 2001> with 3plug ecu has 98

I stand corrected!

[jeffchiz]

dear god how many more times will people get confused between black and silver tops lol

to give you an idea of how much work is invovled in getting 120bhp out of a vtr, the most common route is to fit the s1 rallye cylinder head, inlet manifold, a ph2 cam and a remap plus you'll want the rallye ecu and loom, thats best part of a grand there

or

spend around £300 on a 16v conversion, much less hassle swapping engines than to take the 8v apart

or more to the point this is all pointless if you are turboing, really need to decide what you are going to do and what you are dreaming to do

[greyjasper51]

125bhp from a vtr needs race/rally cam, pugsport exhaust and standalone ecu with standard everything else... Including exhaust mani, it wont tick over nicely....

Pointless unless you have deep pockets and going throttle bodies


If anyone's interested my rebuilt rallye head and inlet is up for sale by the lad that just bought it

If you REALLY set on tuning an 8v without spending out on bodies or turbo, then fitting the above and a remap is the most sensible thing to do

Give you some gains and won't bust the bank

Mine is an x plate and silver top and has a 3 plug ecu so how do u work that out?

because an x reg can be a 2001....

anyway as the majority of people no there is never a definite cut off point ive seen mk1's on plates later than a v reg which isnt supposed to happen, things dont always go by the book

It's a fact... Think you just read it wrong

[blackie_2k5]

Most x reg ive seen were registered in 20001 lol

As said cars can sit in dealers with plates allocated for that time slot that were never sold until.. Or were sold/registered before they should have been

There is always some exceptions.. But yeah in many instances an x is a very late 2000 early 2001... If it was a big dealer he probs got his new supply of cars (3 plug) early and they were straight out the door

Stop trying to nit pick

[mcjacko1987]

my furio was a silvertop, but with single plug ecu, old shape plug loom (not cross over) but phase 2 body. reg is W and down as 2000.
my mate had if i remember a v reg phase 1 furio that was silvertop single plug ecu, basically same engine set up as mine.
around the 2000 year things got a bit confusing imo.
i just try think of it as pre 1999 black top. 2001 upwards silvertop, 2000 a fuck up lol.

but yeah its off the ecu really isnt it, single plugs 90bhp and 3plug ecu is 98bhp

[jeffchiz]

Yea the engine you had was just an early single plug my w reg vtr had a single plug early silver top engine as w reg is early 2000 it was the ones after that had the cross over looms, my house mate is good ar splicing looms and he's came across some wierd ones its all a bit weird lol

In all honestly id rather drive a 120hp vtr than a 120hp vts because there more forgiving with a mistake and you dont have to have them screaming their tits off to make power, the 8v is more progressive... What ive found anyway
