will just port and polished be enough??
or shall i get bigger valves?? if so how much extra bhp will this increase by??

john help lol

if i were you i'd plumb it in as VW intended, if the rockr cover breather was enough for the 2.0 8v thats all it would have had! Plenty of 2.0 8vs to be found in the scrappy, was fitted to mk3 golf/vento, passats, SEATs etc etc.
Bigger zaust valves will help, but its alotta money to spend on an 8v, for the kinda money it costs you can get an ABF, which is pretty much a drop in replacement even down to the wiring since your car is a 90 spec!
Cam choice is a tough one, needs to be matched to the rest of the engine plus personal preference and I'm not really qualified to answer. If it was me I'd get whichever comes up cheap :grin:
The core plug might fit, best way to find out is to unbolt the breather housing and measure the hole, and compare that to the measurements of the core plugs round the back o the block.
-
bith cams are the same price....
cant do abf as i wouldnt know how and ive got 8v block etc....
ok i look in scrap yard and see what comes up
-
fair enough, abf is one of the easier conversions I dropped one into j_s mk2 without much drama.
Well there was lots of drama, but mostly unrelated to the actual conversion. Only engine convo issue we had was the key we were given didnt match the ecu so the immobilisor stopped it running!
-
as long as i get a decent bhp im happy using bottom end lol....
dude ur for sale links arnt working
-
fixed!
my totally standard bottom end & mk2 head got me 141.9 bhp on stealths rollers, though they're known to be a bit 'optimistic'
-
so if i do bottom end with bigger valves and a 272 cam stainless steal exhaust what kinda realalist bhp do u think il get?
-
id say 'actual' 140-150bhp ish. The main point of the 2.0 is the extra torque not bhp though, which is where its at.

torque is the get up and go???
i know mines never gonna be fastest on the road but id be happy with that i thinnk
-
aye, remember that was with a bog std head & cam, no other mods except bigger injectors (cos they were cheap and nearly new!)
-
so p and p head with bigger valves and better cam makes more power??
do i need bigger injectors?
-
yeah it should do. the oem injectors should be able to cope, theres a fair bit of reserve there. I got vauxhall 'cream' injectors simply cos I suspected mine may be faulty and they were nearly new and cheap. Didnt make any difference though!
-
ah cool, will just keep mine then....
its getting quite expensive all this modding
