160-170bhp vtr?

[iw_laurence]

right im toying with geting more power out of my vtr, i want around 160-170 bhp, what do i need to do to get it up there (except drop the 16v in there)

cheers guys, and dont worry this isnt a dreamer thread so please no stupid comments

couple a grand for starters !

[Jorge-]

a turbo

thats fine

a turbo


is there no way of achieving it n/a?

[VTSTomE]

A pretty low spec turbo build would see you there. Then you could save and go crazy!

[AlexB]

seen a charged one with 141 at wheels so 170ish at fly

bout the best way to go imo

[iw_laurence]

ive been toying with turbo but my exhaust system wouldnt be suited for it i dont think...

[Jorge-]

If you can afford a turbo, I am sure you can afford to upgrade the exhaust. You will never achieve that power N/A

A VTS will struggle to see that N/A

[Mike_08]

change it lol

whats involved with supercharging it? is headwork nessecery? and does it require special fuelling?

its not that i cant afford to change it, its that im happy with the sound and dont think i will be able to replicate that with say a 2.5" system

hence theres several vts running over 200 on here n/a :S

to get a vtr there n/a it would be very peaky and have a very small poerband high in the revs
so would be hard to keep in the power

whats involved with supercharging it? is headwork nessecery? and does it require special fuelling?

headwork benefits it
youd need low comp pistons and an ecu to run it (its basically the same as a turbo setup for the motor itself and fueling)

[VTSTomE]

vtr's also have a lower compression than the 16v don't they to start with?

[iw_laurence]

oh ok, well ill get resaearching into it, any specific chargers used? or good websites/project threads to look at?

[AlexB]

iirc they run the samew pistons so id have thought the same compression but im not an expert on compression ratios

gmc iirc sell supercharger kits that allmost just bolt on and map

[VTEC-Saxo]

are we talking about at the wheels or at the fly ? i hope not wheels lol! you will need a hell of a lot of money and a lot of work :D, best bets getting a forged 1.8 stroker kit for the vtr with a turbo maybe a t28 ? and nos muhaha

different pistons, hence why you cant use 16v head with 8v pistons as they will clash

RE the main question, boost is the only way on the 8v unless you have very deep pockets for a NA race engine

[VtsTom]

Theres a lad on the rallye reg with a s2 8v with a sandy brown/mark shillaber engine thats suppose to be 162 at the fly.

He has:
DTA ecu
QEP big valve ported 8v head
newmans phase 4 cam
catcam springs
16v bottom end with valve cut outs in the pistons 11.6:1 CR
Supersprint exhaust manifold and pug sport/scorpion system
SB inlet manifold and R1 bike bodies with larger injectors

IIRC it made 136 atw with sandy

Not bad for a touch over £3000 with mapping etc. BUT what could you get out of a 16v with £3k spent on it? Alot more user friendly power with scope for more is what

see thats why i say im no expert on compressions lol

dnt z cars do a honda engine conversion for the saxo

[stephen34]

vts engine and about 4-5 grand go tbs and cams and good remap its waht i am going to do next year and then work what else u need out :)

Read his first post :S

He doesnt want a VTS engine.

[williamsvts]

i dont get why people want to do things the hard way. just go 16v.

[KamRacing]

well some people prefer the lightweight of the 8v engine so you get a better balanced car.
Personally if the bore size is the same (i dont have any details to hand. I would ditch the vtr engine block, look at the rallye or 205 xs alloy block for lightness then fit all the parts VTStom mentioned.
16v is not the only answer.

I'm working out a lightweight engine for my car and it will cost a lot more than buying a vts engine, but sometimes theres more than just cost as a consideration.

[iw_laurence]

i was looking at the s1 rallye block with a wild cam and a bit of fettling with pistons/headwork. i know its easy to do the 16v conversion but i like to be a bit different... i think im going to get the running gear right then get a bit more out of the engine
