theres the next project a 4wd mk1 :) thats cool

wanna see how close i can get my car to your
obviously we are not sure of end bhp etc as it is a bit of a unknown will email you spec list so far

and will send ya loads of rebuild pics have no fear if ya want me to

pete


4WD? Are you mad? That would be a hell of a lot of work to make a car boring to drive!! No offence (you must feel like i'm always having a go) but do you realise how much is involved in order to do this? An output from the gearbox is the least of your worries. Also 4WD just makes a car boring in all honesty.

good luck with it though! ;)

hi we are going for a hks 1800cc stroker kit including crank rods pistons etc etc
keeping the sc for now but outting it into the engine adn the sc wil grow later in the year but have no fear that will grow but want to get the engine itself as far as i can first
will keep you updated with it
but chatting to the guy we will prob go for a vortech sc when we do
have fun

Hi Pete, I know when we spoke at the Christmas doo and you told me of the plans, I told you I didnt think it was possible and to aim about 50bhp less! But hey ho, Lauren and I are now up there to be knocked down! Best of luck to you buddy!

LOL! I hate it that i seem to always nagging at him, but i'm honest if nothing else as whats the point otherwise?

Pete has mega amounts of enthusiasm for the MR2 and particularly the SC since he got his hands on one. I know this feeling as this was me four years ago. I was going to get mega power from mine, i had all these plans to do stuff, but like any kind of engine tuning the law of 'diminishing returns' always happens at some point. I researched the whole 'getting 200bhp+' issue to the nth degree and looked at every possible option in a bid to get past the limitations of the roots blower (which is the limiting factor). In the end i went and got a turbo manifold made up as i saw this as the best way to go about getting more power from the GZE.

To be fair to Pete he is sinking a lot of money into his engine. I'm impressed that he's going for a full port job and doing all the internals, but if he doesn't ditch the stock SC he's going to hit a brickwall and all that money and extra work which will produce a lovely engine, is not going to realise its full potential.

Ok cool! I think a vortech will go really well on the GZE, with that and some good intercooling i think you will get near to your power figures. The vortech will produce less heat than the rootes blower, plus the added capacity ought to give you another 5% as well. Are you going steel crank then? If so you may as well get some wilder cams to make use of the revs and select the SC to suit that.

You do know though that stroking the engine will make it less revvy and undersquare in config?

I did wonder what you were barking on about with the 4WD thing! :P fairynuff.

pete your nuts but good luck!

i still have a MASSIVE soft spot for the old MK1 MR2 and more power is what i always wished mine had.

looking forward to the end result. what kinda time scale you looking at for the whole SC thing? and what about the turbo MK1?


i'd of gone the paul woods route with the 3SGTE engine. i'd of whacked a rev3 engine in as i'd love the looks you'd get in a MK1 with a dump valve going off out pacing scoobs hehe :twisted:

i prefere more modern cars now, interiors are better and creature comforts are nicer but would love a MK1 for a mess around again one day! :D

Re: Big power MK1

hi lauren again
yeah looking at cams as well as bigger valves
i know what you ar sayng about the sc but i can afford to do the engien now and save the sc for alittle later in the year
as for what the revving etc are doing i am leaving that up to the builder he know 10000 times more than me which is not hard so
bot sure on what the crank is
as i know more lauren i will let you know
as for the intercooling he has several ideas how to imporve that greatly i have a standard sc intercooler any one intersted

and chris as i said wanted to stick with the 4a adn as lauren keeps saying i love trhe handling on the mk1 does what i want so sticking with it
especially after how long it took me to get it
not sure on time all parts are on order so as soon as they come in it will be going otgether
oh andi am hving a dump valve so do not fear i will haev the sound and sound aof a sc which i love

Ok cool, Pete.

One thing though, try and learn as much as you can as soon as possible as far as engines & engine tuning goes. I only say this because the first thing i'd want to know if i was going to buy a crank is, is it steel?

This is mega important. I'm guessing the crank is costing you serious money? You really need to know about stuff like this. I'm not patronising you, but i don't want to see you get ripped off. A bit of knowledge here really is essential IMHO.

Keep us informed as to whats going on though. If there's any questions post them to the list!

hi lauren cheers for htat
yeah i was there stripping down the engien as we are looking at waht to do and i learn a lot then and i iwl be there when a lot of the work is done ot learn as mucha s possible
as for crank i take it it should be steel
i is a hks cranks so i would have thoughts so but iwll check going up there 2morrow

cheers again
and will email you as well ot keep you updated

Yep i would expect the crank to be steel tbh.

Having a steel crank makes it a bit of a special engine. You should be able to rev it to 9K no probs. You will probably need to have solid tappets and some decent valve springs to avoid valve float. You can also get some fairly wild cams with a power band up to say 8.5K and you can spec the SC to run up to these kind of revs. With decent intercooling you ought to be able to reach the power levels you want to, no probs.

sorry pete but im still trying to get my head around why you are going the SC route.As lauren says the SC will become inefficient and create more heat than power unless you plan to radically alter the SC type and intercooling.....but then this throws up the question about using a supercharger at all? All superchargers demand power from the engine to work so i would have thought with an "all out big power" 4a it would make far more sense to fit a turbocharger to your engine than an SC? Am i the only one who sees this? The turbo will produce a shedload more power and at no expense to the engine,ie its only using exhaust gas to power it and not dragging on the pulleys.If you were aiming below 200bhp then the SC is fine but i dont see the point in compromising with the very thing thats creating your boost when you are going all out on the rest of the engine,surely you have got to fit a turbo to that engine instead?

If this was me building this i would instantly buy a carl crawford turbo manifold,ditch the sc,make the intercooling as daft as you want,chargecooler,WI....and i think you could smash 240bhp never mind reach it.

But im not building it,its your project and if you are determined to keep it as a SC then fair enough,i just dont see the thinking behind keeping the SC which is ultimately going to restrict your power when you are doing so much and spending so much to modify the rest of the engine to free power.You mailed me the spec list,its very impressive,should be absolutely mental...ive huge respect for anyone doing this type of thing,the above are just my thoughts on it as a professional mechanic,please dont take any of it personally,i still think its a fantastic project.

I agree with you Paul that the tubby conversion will give Pete the power
but Pete wants to be the first sc to get to that sort of power.

He has a great garage that will be doing the work for him and yes it might be expensive but Pete will get there i'm sure!

You wanted to be the first in the country that had a tubby and now v6,Pete wants to be the first sc that has the power,he knows it's gonna cost him but his will be the first and quickest mk1 sc in the country,if not the world!!!

Re: Big power MK1

hi paul
i can see where you are comming from for sure
but it is also an insurance inssue they do not mind if i keep the sc but as soon as i say its changing to a turbo they do not like it much. they will insure it with the stuff i am doing and a bigger sc but do not like the idea of a turbo i may think about changining to a turbo instead of a bigger sc later in the year after i have changed insurance companies but for now i want to concetrate ont he engine and then see when i am going to change the forced iduction i want to se what it produces first before i either change the sc for much bigger or put a turbo on it and blitz do a turbo manifold for the car anyway so will have to see later in the year or in next winter i expect
thanks you for all your comments please keep them comming
but as i am not yet spending any money on the sc i am just spending it on the engine then that leaves me to play with the forced induction later on as to what we decide to do i may still go turbo but want ot do the actuall engine to start with so i have a very strong powerfull base and like you say witha nice turbo that will produce a lot of power and when i do it will porb be cheaper than a bigger sc
thanks again

I've been trying to sell him my Carl Crawford turbo manifold all along as i do agree this is by far the best way.

Steve, Paul is talking about turboing the GZE not transplanting a 3SGTE.

I have to agree with Paul here as a turbo will always give more power.
