I know people say its not worth it and its really costly, but i want to tune up my golf 8v to around 150-180bhp
(i know i sound crazy but thats me) please dont ask me to do a engine swap, im not going down that route cheers,
im also including Nos as a edition to reach 180bhp, and a basic turbo setup pushing 3-5 psi max, (anyone do custom map turbo setup on here) inbox prices pls.
can someone give me a list on how to go about this?
how to start off?
Advice neeeded urgently off everyone who can give me a pointer,
Its currently got stainless steel back box and removed that big silcencer box that is attached behind back box, airfilter.
i need a step by step modification to reach this BHP, also quote the garage that will carry out the work, i live near midlands, i will keep everyone updated in my signature as a checklist on whats happening.
-
you should easily see 180bhp with a decent turbo set up. even without the nos. as for the cost. pretty frightening I would imagine.
-
a very basic turbo setup, 3-5 psi and it shouldnt harm the 8v engine,
i know cams and a chip would be a good start? what about ecu? standard ok or would i have to use custom? if custom point me towards the right direction please, who does them, all info appreciated. fuel pump? use vr6 one?
-
Have a look on the US vw sites as well as American ebay for parts, there also used to be some good threads on vw vortex as turbocharging the 8v is popular across the pond although their 8v used a slightly different engine.
-
I think Nuespeed sell supercharger kits for the 2.0 8v, but they might be specific to the US ABA engines.
-
Really not worth it tbh
-
Ive cammed my 8v and with chip, lightened flywheel, head port and polish, same with tb you should get 150bhp
any more and you will need wild cam, high compression pistons, knife edge crank, itb's and a costom map with aftermarket ecu. You should get about 170/180bhp
but your looking at £10,000.
So do what im doing. Sell up and buy a m3. Straight 6 itb's as standard and 350bhp
-
Exactly
-
Do it.......be different. Good luck.
-
Buy a 16v for a few hundred quid and you'll have 150bhp straight away.
-

cheers pal, why act like every tom dick n harry and go buy another car, and then another car whoops me i get told to buy another lol,
im tuning this baby over the next year or two, watch this bad boy develop, ...WATCH THIS SPACE... :wink:
I asked for advice onTUNING not whether i should buy another car lol
But never mind... i think Nos will be a decent option after cam work and gas flow head and chip. should see around 130- 140 hopefully.
-
Decent cam, air box mods, ported tb and inlet will see 135 ish bhp.
Lower fd and light flywheel will give you some response in acceleration, add nos and you have 150ish bhp.
Thats it for 8v without spending bucks on forced induction and an engine that can take the extra strain.
Engine management to run turbo is even more.
I bought a tdi engine to use for a petrol turbo, ghetto style granted but with a few bits I reckon I can make it work.
Trouble is im lazy
-
Don't listen to the haters. I made a low boost turbo set up (8psi) for my 1.8 16v clio years back for just under a grand. The most expensive bit was sorting the ecu, but since then iv used a couple of unichip units. These unit can be brought off eBay to save a few quid and be wire in by yourself if you can get the diagram then take it to be remapped. Research, trawl ebay for parts and be creative with the welder.
iv keep toying with the idea of turboing my 8v too. Do it! I might start collecting parts when i get back of my hols in September. Crack on pal, what's the worst that can happen to the motor? Blow it? £200 for a new one. Let us know how you get on

yes its better to report then drop to his level, anyway jamo i was looking into a short shift kit today and couldnt figure out if this is the 100% correct 1?
mines a 1998 Golf gti 8v, also is this all i need to get short shift setup on my car?

Anyway yes thats what you need to short shift. Might be a good idea getting some new bushes for the rest of the shifter set up as they can wear out but check how yours feels. Sure u can get repair kits still off ebay for 20 quid.
-
mines go fine into each gear, but crunches if i shift 1st to 2nd @ around 5000rpm quickly.

i know a guy named Brian in derby, place called POWERHOUSE, he has the old AE82 mk1 gt corolla hatchback,
with a turbo setup, and some how he managed to do a 4x4 conversion to it,
believe me this guyS Corolla has put impreza's to shame, il look up to see a video on his corolla, he was willing to turbo charge my mk2 golf 16v for around £2000 +VAT(4 years ago) was saying a basic turbo setup would run fine, as long as boost is set at a safe 4-5 psi...(HALF A BAR) or even supercharge it.

That dont sound good. You will want a strong gearbox if your gonna be running more power. Sound like worn syncro between the gears. Try changing gear oil first it sometime can help matters.
-
yeah il try that, its going in for full service this week, so il try that, im going to use using 5w40 semi synthetic shell performance oil, is this ok for my engine?
-
Depends on miles really. 10w 40 might be better.

its just hit 112,000, paper work shows old owner had engine rebuilt @ 80,000 ish so im not sure what exactly to use.
-
I'd go with the 10w/40 semi as mentioned by Tweed.
-
Cheers Fella's il do that, :wink:

Hi mate, I was in your shoes around a year ago, and I posted nothing on here, as I knew all I would get was, 16v, vr6, 1.8t blah blah. So I did lots of research and was all but ready to go down the supercharged route. I then decided on doing bike carbs due to ease and cost and clean looks really. Have you looked at ITB's or bike carbs??
Also there is shed loads more info on Vortex, due to the yanks tuning the 8v a hell of a lot more then here.
A well put together ITB'd 8v could breeze your goal. Would cost £1500-£2500 depending on management and where you have manifolds made, ECU's wired in etc.
Bike carbs done right could see 160-170BHP. Sub £1500 if your willing to do some leg work to get it done. Easy conversion.
If you are interested in bike carbs I can give you more info as I did a lot digging and research before I did mine.
Best of luck to you.

As cool as bike carbs look and sound aren't they a step backwards in terms of efficiency and reliability? :undecided:

In terms of effiency... Maybe, however they seem to make more power then the standard injection.
As for reliability, it's in a whole new league. Apart from the coil pack dying on the A1 last week, it runs smoother and more reliable.
Also contrary to popular belief, there not that un-economical. I did 250m in 3 trips over a weekend and drive about as uneconomically as possible and it made 25mpg. Round town again, driving rather uneconomically it makes 15-20.
Its not all about BHP tho, its about hoe it drives. My car revs to 8.5k and flies round the clock. It may only be slightly more power then a 16v but I've yet to meet one that stay anywhere near me. It could just do with a longer 4th gear.
-
how on earth do you get an 8 valve agg to rev to 8500k? :shocked: did you put the cylinder head on without the valves in it lol

mate go for a 16v box and fit a VR6 final drive
mine is similar ratios to this however iv got the mk4 02J box from a mk4 GTI 2.08v (same ratios as 16v mk3 but ib fitted a Wavetrac limited slip diff and VR6 Final drive, seen my car bounce off the 160 MPH mark

Ahh cool, been trying to come up with a solution. Can i get a VR6 Fd loose or will I have to buy both full boxes??
My car seems to hit 127 in 4th with 1.5k left.
130 with about 2.5k left to pull in 5th :(
Would a LSD be worth the expense??
Thanks for the advice buddy.

iv pm you mate :-)

Stage 2 crossflow head, Hi flow valve kit, springs, retainers etc, light followers, high lift cam, vernier pulley and a lightened fly. :cool:

Thats one happy looking 8v engine. Looks so good. Strong work mate.
-
simply amazing engine bay, now thats wot i call unique :wink:
-
Awesome :cool:
-
Lovely looking engine bay and nice to see someone tuning the 8v rather than doing a conversion.

I bought a FD off a vr6 owner who had installed a 16v FD ( so he got better acceleration)
But u may find it easier to just get the vr box and get it stripped
My LSD is a wavetrac and not cheap at nearly £1000 when u get the APR bolts etc
But their are Cheaper alternatives
I'm at around the 350 BHP mark and I have to say its the best mod I did was the gearbox
It's worth it all mate honest..
