Was a bit harsh though parker i can see why he was angry .. if i read the posts right 8-[ we cant all by £3k rev3 .. end of the day rev1/2 are 1.3 to £1.5k :thumleft: great starter kit :thumleft: .. being told you should have bought a rev3 is pretty dark and not helpful


Dude, nice rev 2 turbos are 3k! I paid 2850 for mine and it's in lovely condition. Rev3+ are 4-6k! I assume you're talking about turbos, right?

Yes please, always wanted to see other peoples opinions on the rev 1/2s please.

Im currently standard with an air filter, exhaust (still got cat) and mbc set at 0.9bar. I have an intercooler to fit. Its a rev 2

To be honest, on a revision 1/2 you'll end up spending more to get to 300bhp fly. I was not saying this in a snooty way. Just seem like penny wise pound foolish to me.

Extracting power is rarely cheap so it's good to start from a good foundation.
At the moment you want 260bhp odd but you will want more, all of us do.

Where as a rev 3 owner can get away relatively easy and cheaply to 300bhp fly. You will need...

Metal HG
Rev 3 fueling
CT20b turbo
Some sort of ecu piggyback.

This was all i was outlining

However first thing I'd do is get a bigger intercooler and FIRST get a boost gauge. Very important

Ok ..

stage one mods , airfilter, 3"free-flow exhaust and downpipe. and 4" intercooler kit.
ct20b .. this is a must .. plus i ported the wastegate and manifold.
Hks vpc (map sensor rev3 upgrade) and afc .. tuned by wideband to 10.8afr
fpr to help with tuning.
mines ecu for boost maps to 1.2bar.
water/meth 50/50 injection.
Hks evc 5 on 1.1 to 1.2bar.

All in 300 hp .. i think i got close 8-[ .. wish id dynoed it :cyclops:



Think thats it .. had a hks bov .. part from that , that was my setup... best of luck rev1/2's can shift too :thumleft:

Never did the mhg in 5 years .. and it held ... not that this is a smart thing to do 8-[


Yeah sorry mate just seemed reading between the lines your comment "should have bought a rev3" was a bit dark 8-[ to a rev1/2 owner .

I'm saying in the long run you'll be spending more for the power.

If you are doing this over years of tuning that ok. I think you got luck 2mad. An ECU alone is £500+

How much can you get with just changing the ct26 to a CT20b?

Yeah that was my journey .. i could not aford 3k for a rev3 but 1.2k for a rev1/2 was on the cards ... a ct20b on a rev1/2 can see the same 300fly hp as a rev3 you just have to work harder for it .. payed 300 for my mines and blitz ecu's had both over the life of the car .

Ive been looking for a hks vpc for quite a while as want to get rid of the afm but dont seem to see them anymore. Plus wanna run a dv without upsetting the fuelling.

Just remembered, also got a decat to fit in the garage. Id want to fit a ct20b at the same time or maybe a ct26hybrid - something that will hold boost to the redline.
Thats one thing i noticed on track - the boost dropping as soon as you raise the revs with the ct26 :(

I've nothing against them as that's exactly what I did with my first mk2 turbo! :)



:thumleft: ... I have atot of love for the rev1/2 .. there great cars can be had for peanuts .. and a ct20b and a few tweeks later can really haul ass :thumleft:


Like I said earlier, I bought a Rev 1 engine myself, but I did get the Rev 3 upgrades, like ecu, injectors...and whatever other gubbins you need. Peter did the work, I don't confess to be a mechanic.

I was going to stay with the ct26 turbo but there was a fault with it so was forced to change it so got a ct20. I have to say though, I feel the ct26 turbo is a bit more fun on the streets...

Thing is with the Rev 3 upgrades, it's all or nothing really, so you have to buy everything in one go barring the head and the turbo.

Even I am thinking I should have just bought a Rev 3 engine now though, but like already stated, it was cheaper to do it this way, and my engine was stripped down and all seals, gaskets and bearings replaced ect...so in the end it was expensive but done properly.

I guess its right if you want a straight bolt on no alterations required job.

re this.
Are we ruling out then Garrett conversions or a exotic KKK job in favour of a ct20b :?: :-k :whistle:

No course not but a ct20b will unleash the mr2 turbo full potential on a stock mota for a very low price .. if you want 320hp or more then other turbos are available :thumleft:

Well thats something else to be on the hunt for.

Did they use those in any other cars, to make the scrap heap hunting easier.

I think I can guess what the answer is though.

I find it amazing how so many people write off higher boost pressures on a gen2. I stripped mine down way back when, got original O/S pistons from toyota, installed new belts, pumps, pulleys and tensioners, had a freeflowing exhaust, measured the injector flow using a beaker and stopwatch, drove it in nice an smoothly for almost a 1000 kilometers, then upped the boost bit by bit to 17psi.....had no problems hanging with stock gen3 at all. Did all that for 4 years with an untuned CT26 and a stock gen2 headgasket and gave it the beans on the german autobahn too (best was 30min full throttle!). Took the motor apart again as part of my new project and everything was spick and span!

If you make sure the bloody thing is in perfect working order before upping boost and then do so slowly then i refuse to believe a blown HG or broken ring land is going to be a fact.
