That is exactly the point. You would have to build a dash or 4G62T to make anywhere near what the Twin cam can do standard. I personally wouldn't waste my time performing 'extreme' mods to the single cam engines as the VR-4 can do it straight out of the box. A standard DOHC VR-4 will happy live with 17-18 psi and around 250kw's (at the flywheel) before you really start to compromise reliability. As of next month, mine will be running up to 25 psi and will have over 300kw's, but then again, it's got forged internals... :P




Mate your a Genius. :mrgreen:
well said i hope eclipz understands know. :D
i was bit confused power at the wheels or fly! :oops:
good luck 300kw :P
thread can go back on topic then :roll:

Whether to fit a dohc 2.0 or stay with a sohc probably depends on your budget and your goals and what you have to start with. Sure the power potential with the 2.0 dohc is greater, but unless you are trying for more than maybe 150kw at the wheels, the multipointed sohc option works out cheaper for most people.

ok genius how does it work cheaper 150 bucks muiltipoint+extras like distributer , water pipe work fitings ect ect
most problably by the time muiltipoint is on it 350 bucks then you need injectors evo ones200\300bucks
then you need fuel pump 100 bucks then you need ECU like microtech 1000\1100 bucks then you need electrician for loom 400\500 bucks
then you need dyno its problably around 500 or 600 bucks most of the time you need to dyno a few times .
well you do the total

if you are talking about stock 1.8L its got 110kw at the wheels
and vr4 stock 140kw+
is your cordia the one the dump pipe blow up?
livewire isnt his car for sale 4,000.00 know his car yes i would put my money on
cause his car was done proper but ask him how much he spent on it!
i think you need to go to page one and read up to page 3

A VR-4 makes nowhere near 208kw's stock, even at the flywheel. More like:

~130kw's for the automatic with the tiny TD04 turbo
~150kw's for the manual VR-4 with TD05 14b turbo
~179kw's for the manual Eclipse with TD05 small 16g

what about Tc06 with automatic :)

ok genius

Thanks for recognizing my abilities. :)

Lets break it down then: $150 for multipoint manifold and distributor (ok but I picked up this for less than $100 at the local wrecking yard). $100 for 2nd hand injectors - you don't need to buy evo ones, you only need ones that are large enough and that will fit. 2nd hand aftermarket ecu might cost around $300-$600 if you shop wisely. Tune up, well that depends, mine cost $300 from Mildrens.

Compare that with a dohc install: engine costs $2000-$2500 from an import place, but you might be lucky and pick up someones reject for $1000 or so. Then you need to fabricate an engine mount, cost of probably $100-200 if you cant do it yourself. Then you would look at tidying up the engine which at a minimum would mean a timing belt and tensioner - unlike the sohc, if the timing belt fails on these engines then its rooted. Also your going to need your exhaust modified to fit your new engine. Not to mention new clutch, hoses, wiring and all the other things that are done anytime an engine is replaced.

You also stated that you would need a fuel pump for the multipoint conversion, but this would apply to both upgrades. Plenty of vr4 conversions have ended up costing their owners well over $4000 but a typical multipoint conversion would come in at less than $2000.

Standard tc06 has a small compressor. Auto vr4 engine has small injectors.

Image Hi guys just a pic of my other toys engine, 320 hp at the fly soon to be supercharged Image. 4.11 gears shift-kitted auto. 1966 Ford Mustang (convertible). The reason for this post? I'm a 44 yr old drunken wanker saying numbers don't matter, enjoy the ride! be it Cordia , Ford , Nissan or Chev.

Your car: MY car? hmmm a black hunk of metal that moves once every year
FYI!!!!!!



Problem sovled :P

Spent a few hours on it today turbo change valve stem seals cleaned every thing no more smoke :)

Dont think it was the stem seal as the all look pretty ok accept for no.1 inlet BUT they are done now turbo is on looks good few minor leaks from stuff we ran out of day light QUICK! didnt have the head torqued down till 530 - 6 and well had no daylight left so work in the dark for a bit got it started
sound great dosnt blow smoke cept for whats left in the exhaust but that mostly burnt away in the first 2 mins of reving.

cannot boost due to the turbo we got has the compressor housing on a 15 deg angle compared to stock, and stock cross over will not fit in so it was running 0 vac, any smoke it blew was prolly from over fueling but yeh all sorted!!!!

all in all took about 8 hours of work
Head off
turbo off
manifolds cleaned
replaced valve stem seals
turbo and head back on exhaust manifold bolted back up

needs a tune and a custom cross over, i have a cheap solution already worked out just gotta measure some things.

REALLY dont feel like taking the turbo off again and working out how to rotate the comp housing :D
