turbo or supercharger

13th December 2009, 20:29

Hi ppl i have made the brave move to do some sort of asperation change to my saxo im planning a 1.6 c2 engine in it giving it like 125bhp which i have saved for but i also get £2500 in student loan in january so want to turbo or supercharge it i have all the stuff like new brakes etc so just need the kit are there people who make the stuff and fit it or is it easy/hard to do, would u buy a turbo or supercharger which would u get more gains from thats the main question really?

Have many people supercharged a saxo or is it mainly turbos?

loads of supercharged and turbod saxos around.

i wouldnt spend my student loan on it though.

Go turbo mate. Luthor1 is putting a kit together soon i think including his ecu which i would recomend. As for spending the student loan on it. Prob not the best move you have ever made ha. Unless your minted.

Just my opinion to go turbo. Love them

will struggle to do a supercharged set up for £2500, basic gmc kit is around 3600+ vat and thats not fitted. If your after a cheaper build would say turbo but if its driveability and reliability your after i would suggest supercharged.

do blow your student loan on it. You will spend all your money then need another grand or something and have a non running car and zero money.

Turbo is much cheaper and easier on a budget

Yeah, I'd go turbo every time. As others said, don't spend student loan on it!!

why would you go turbo though?

i can only see negatives from fitting a turbo to a saxo myself, too much stress on transmission, no grip from the sudden increase in power, making the car not much quicker until you get to higher speeds because you can't put the power down...

supercharger is a much more linear power delivery and although will give the same power gains, the stress on transmission is much less due to the power building up as you go through the rev range as a pose to the turbo where it would be nothing, nothing, nothing, big wack of power and then you say, oh shit i need a new gearbox. again.

i could be totally wrong here, and please tell me if i'm over exagerating it but this is the view i've always had on saxo's and generally fwd with turbo's.

BE conversion pretty much sorts the gearbox issue. And as long as you don't go for a massive turbo (whereby it's still possible to reduce lag), you won't get a massive amount of lag.

apart from cituning, where can you get all the right bits for doing a turbo conversion though? i don't mean like the cheap chinese ebay jobs though!

ATSpeed, DPEngineering. As said earlier in the thread, Andy (luthor), in the future. Not to mention companies like Pug1off etc could probably supply them.

Just buy something faster.

How reliable is running throttle bodies?

14th December 2009, 12:08

throttlebodies are the same reliability as a normal engine if kitted correctly

the thing is turbo's dont go nothin nothing nothing powar.......
if you have a huge turbo then it will be similar to that but most well specced turbos will give very very smooth power delivery.

look at all the modern fast hot hatches... how many of them are superchraged compared to turbo?? there are reasons for this.

i'm not trying to be an arsehole, i really want to know because at the moment i've got the money sat in the bank and i was going to sc mine over christmas, however, if i could turbo it and it be just as reliable i'd do that instead because i'll have change left over from the turbo kit.

if a proper job is done they are reliable. Its when corners are cut on boosted applications they go wrong. GMC are expensive because they dont skimp, they have a proper well thought out setup with quality parts.
There are cheap kits available from other people and they are sometimes cheap for a reason.

because turbos give good power, low noise, low emmisions and good fuel consumption not to mention lots of room for potential..

you could quite happily tune a 1.6 turbo to around 240bhp and have near perfect emmissons and noise where you would never get that on a n/a engine and it would still be difficult'ish with s/c.

to make a reliable turbo conversion you need to keep everything COOL. make sure the inlet temps are as cold as poss, heatwrap everything to keep bay temperatures down and so things dont melt. the mapping is very important as its possible to keep an engine "cool" with mapping. if you do this and spec the car accordingly then you will have a reliable car and have some drivability.

Maddison - I don't think your questions are in anyway poor.

I've mapped a 260bhp 106gti with a supercharger. It had forgies, steel headgasket, intercooler etc.

I've mapped a 195bhp turbo. It's a stock engine, with 491cc injectors, GT17 turbo running 6psi, intercooler and my ECU.

The driveability of the turbo is FAR superior. There is absolutely no lag at all. It makes boost from 2000rpm and it doesn't come in with any kind of kick. It's completely linear.

Superchargers make poor low rev performance since the boost is proportional to revs, this is annoying because you end up having to cane it everywhere. With the turbo you can just grunt it through 2000 - 3000rpm and really get a move on.

Ben_vts has the turbo, and his intake temps never went over 30 degrees on the mapping session, so temps are largely irrelevent at this low-boost configuration.

Ben has been running his turbo for thousands of miles now with no probs at all.

i've obviously not looked into it enough! and i've clearly been too influenced on the supercharger route!

Luthor - when would you be putting a turbo kit together? and how much will you be wanting?

take a look m8, there are a few companies out there,
http://www.dp-engineering.nl/

these are one of the best for turboing saxos, all be it expensive, but u get what you pay for, http://www.saxperience.com/forum/sho...ight=saxodaffy
this one was built by them, was awsome nd reliable b4 the accident.
