:) Hello

I am considering to purchase a turbocharging kit for my Civic Type R
(T3/T4 turbocharger)

But before I do I would like to know what other areas do I need to also upgrade on. This kit will add 200hp.

Many thanks
 
Adding another 200bhp is massive! Personally I would strengthen all internals - forged pistons. Go with a lower compression as well or you risk suffereing from engine knock. Whos selling the kit - I get asked quite often for turbo upgrade details for these cars. Fuelling will also need to be uprated - adding that much power will make the car much more thirsty.
 
The link didn't work - so I couldn't see the site -sorry!

When you have a lot of pressure in an engine there is a danger that the petrol will just ignite under pressure before the spark happens - potentially causing the piston to fire before it is ready and really wrecks the engine if this happens. Knock is what this phenomina is reffered to. The octane rating of petrol gives an indication of how much resistance it has to knock - the higher it is the better but the highest you can get on uk forecourts is around 97RON.

Lowering the compression of the engine will help with this. Compression is the amount of air fuel compressed as a ratio ie 7:1 takes 70ml of air and will compress it to 10ml when the piston is fully compressed ready for the spark to happen - aim for around 7:1 for a turbo application 9:1 would be too high.
 
Hi,

Sorry mate but if you bolt this "kit" straight onto a standard motor you will break something.

The basic reason for forced induction (turbo or supercharger) is not to increase compression or the maximum pressure in an engine cylinder, it is to increase volumetric efficiency (will explain that in a mo) although forced induction is the most effective meathod of upping compression.

If i confuse anyone wih the Volumetric Efficiency bit let me know and I will try to clarify things. :wink:

When a naturally aspirated engine suck air in, it can only draw so much in before the intake valve closes and seals the cylinder. The average N/A engine will pull in around 60% of its volume, so as a result is only 60% volume effecient.
The only way to improve this is to force the air/fuel mixture into the cylinders (forced induction) thus filling them more. the average forced inducted engine runs at onver 90% volumetric efficiency.
If you increase the amount of air/fuel in the cylingers by 30% then as a result you will increase the compression by 30%, which would be too much. In order to keep the final running compression the same, the inital compression (without boost) has to be dropped to compensate.

I think that makes sense. :?
 
Ooh, forgot to give examples of the result. a 2.0 N/A motor will use approx 1200-1300cc of its capacity. A turbo'd or supercharged 2.0 will use 1800-1900cc, producing more power as it is able to burn more fuel. The mnore boost you run, the close you get to using 100% but for some technical reason I don't understand, apparently thats not possible. But the main benefit from increasing boost is to increase the final compression ratio and getting a harder bang from the air/fuel mix in your cylinders.

Its been yonks since I last tried to explain this to anyone so I may be adding bits that I have forgotten for a while yet. :rolleyes: :lol:
 
ok I sort of understand what your saying :? Is it the actual turbocharger thats not right for my car because the power output is too much. So what is the next step for me??? Your comments would be appreciated :)
 
You can reduce the compression ratio - with low compression pistons (They are a different size to the standard pistons so the cylinder it sits in has more 'airspace inside) you could rebore the block as well (it makes the cylinders wider and then you fit wider pistons.) Or you put the head higher up with thicker gaskets or fit a deeper head (thick gaskets is not a fantastic option due to unreliability of them.)
 
If you drop the initial compression ratio this turbo should be fine, like wayne says there are many ways to drop compression. I have also been readingsome of my old books from college and my apprenticeship. Occording to some of my books, if you can reduce the boost pressure to 5-7psi (as opposed to 25-35psi), and used the higher octaine fuels available (e.g. Shell Optimax) you should be able to run a turbo on a standard engine.

It seems to be a bit of a grey area. Some sources of info say you can turbo a standard engine others say you cant. Find out what the compression ratio on your engine, if it any higher than 9:1 then I would think you need to drop the compression ratio first. I also verymuch doubt you willsee a 20bhp increase from this, probably more like 30% power increase from what you already have (still a good power gain).

It would be worth contacting Turborevs and asking them a few questions. Is everything needed to fit a turbo to your engine included in the kit, if not what else do you need and where can you get it from? Can they garantee that the kit will not damage your engine?
 
Thanks guys I appreciate your help in my project. I will get in touch with turborevs and establish if I need additional equipment and also find the compression ratio of the Type R. Will keep you guys posted. :D
 
Hi guys I got in touch with Turborevs and this is what I asked

'Can you tell me if all the necessary items are provided to fit the turbo into my engine. If not what else do I need and where would I be able to purchase it from? Also is the turbo safe for my car and not cause damage'

There response,

''Additionally you may require a 2.5" downpipe (if your car doesn't already have one fitted) and standard fittings such as the gaskets (these are parts which you fitter should provide).''

what are your comments :)
 
Just found out that fitting a turbo to a Lexus takes a competant fitter 40 hours work! Its worth bearing this in mind also.

I really am not very confident with their reply - perhaps you need to ask more specific questions like "how much boost will I get on my specific model?" "Do they offer a fitting service?"- if not is that because of a problem they don't want to tell you about? "Has anyone else they know of fitted one - can you be put in contact with them?"

You will NOT get a 200bhp increase without blowing up your engine the minute you turn it on! 20bhp perhaps if as fingers suggested you dial down the boost or perhaps a little more if you get the engine work done. I think a supercharger would be a better bet - this was what they did to the Typre R powered Arial Atom if I remember correctly.
 
Turborevs recommended the following companies to fit the turbo in

Prestige Car Specialist
463 Balmoral Road
London, E7
Tel: 07831 348 015

K.L.G. Services
Unit 3 Elkesley Park
Gamston Airfield
Retford
Nottinghamsire
DN22 0QL
Tel: 07900 141384

I will get in contact with them to find out more. I have spoken to other people and they have commented that supercharging my Civic Type R would be more better than placing a turbo kit.
 
I saw an advert on ebay a guy selling a civic Type R with a

"T28 TURBO CONVERSION BY PRISM MOTORSPORT"

There contact details are:

Address: Prism Motorsport
Unit 24 Redburn Industrial Estate, Woodall Road
Enfield
EN3 4LE
Telephone:020 88046984

I might also get in touch with then and see what they say but I think supercharging it seems more safer.
 
11:1 is probably the highest Petrol compression ratio around - no wonder they specify that only high octane fuel is used!
