totally aggree, but most ppl just want big power for little cost these days, boost makes that easier
bodied saxos are good fun cars, but as said, the bang for buck isnt as good, and when you can spend the same on a car and get X amount more power, its really only the obvious choice(well to me anyway), it really all boils down to what you want out of the car and your money

Agree all round...just to the average Joe they really need to learn how to drive properly first to make use of any extra power.
One bloke at work was going on about how he was screeching the hell out of his tyres and smoking them at his first ever trackday and that he was so good people were pointing.
Yes i kindly pointed out to him that turning in early and mashing the foot flat to the floor isn't the quickest line for a FWD haha!

yes every bit as good if not better--but you expect me to say that

but if a 20% saving is not worth considering get the 708,s I have sold 20+ sets of these now and had no complaints of any kind
In a previous post someone was saying that the knowledge is now in the public domain --it always has been --but it how you match all the components of the engine together +then spen the money on getting it mapped right .
It still suprises me how many spend fortunes on bits shiney + otherwise ,then get very tight on getting it mapped correctly --not a recipe for getting the best from your project --there is no miracle 1 hour solution to dialing everything in to get the best

And how much work you're prepared to do yourself.
E.g. - massive budget, go boost and can pay a company to do it (not that i would as they rip you a new bum hole)
Large-ish budget and prepared to do a little bit but not loads - no point going boost you'll give up halfway through. Bodies are the better route for this situation but you'll be gutted when someone spent the same about and got way more power with more upgrade options for the future
Modest to large budget, prepared to go the extra mile and put the effort in yourself - boost all the way!
limited budget - you'll struggle to do either

This is what makes me laugh as well. IMO the map is the most important part of the build... make sure you get a mapper you can trust!!!

Boost isn't just about big bhp it's about useable power - so much more across the rev range than n/a

i seriously thought about keeping my 16v engine, camming it, bodies, standalone etc
but from what i could see, i'd spend as much as i would turbo-ing, for the sake of what, 30bhp, and i'd achieve that extra 30bhp way up in the rev range and have to rag shit out of it everywhere to use it, because the power band was so narrow
so i looked at turbos, saw that i could put my foot down in third at 40 and maybe actually accelerate at a decent rate, rather than having to drop to second, and decided that suited me far better
pretty tough call though

yup, aslong as you get a decent turbo matched to the engine. otherwise you'll be worse off lagging away waiting on 4 or 5k coming round before you can even make boost.
as said, its no an easy choice, i would build myself, and play with turbo setup.

you got that all wrong turbos only make power between 6,999 and 7,000 rpm N/A engines make power 1 and 10,000rpm there is the issue of no torque to go with it but torque is just for bragging in pubs

Ill certainly be heading down the boost route with the latest project.
Had TB's on the Saxo and honestly believe with the setup I had it was the worst money I spent on the car in terms of performance.
Sure if you're aiming for a very high spec N/A engine with all the trimmings and alot of internal work (Similar to/above the engine currently in AlexB's 106) then yes from my experience of a lesser spec internally and having been in Toad's car when it had AlexB's engine in, i'd agree that its a worthwhile modification but itll need high investment on the internals aswel to reap the benefits.
If you already currently have a decent map on a cammed 16v engine and you're simply looking to add TB's to that you'll be massively disappointed. Having had mine on the same set of rollers there was a pitifully low increase across the range figures wise (BEFORE: being cammed/mapped and AFTER having applied tb's to it), not worth the expense.
Usually thats a point thats made early on in these threads but can't see it having been mentioned thus far. If you're starting with a standard-ish engine common sense option both financially and for performance is with boost.

Sounds like TB are just a waste of money then so why do people rave on about them

They can be good and worthwhile but you have to spend alot (more than you'd spend on a boost setup) to get the best out of them
Adding them to a 'mild' spec engine is where theyre in the realms of a waste of money

You know what sod turbos, sod tb's get a trackday and tuition and buy yourself a video vbox and get better at driving first.
Turbo's and tb's are like black and white some people like one others liek the other...

so if you had 5000 to spend what would be the best for power when you put your foot down i was going to get catcams 708 and omex ecu Jenvey range TB for now then forged pistons later on but do like the sound of a supercharger will have to look into this first as its all new
