Hello, im new to this forum and have heard good things about it and its members have a wealth of knowledge to share so im hoping someone out there could help me. Ino this question keeps coming up but everyone likes the answer to be specfic to their needs lol.

Im 19 and cant get insure on a vti civic, so im considering buying 1.4 ek model and chnaging the engine to either the b16a or b engine, with maybe even plans to turbo it. Ive been researching this on this forum from members that have carried out this turbo conversion and have gathered information on the parts i need to upgrade from the stock engine to carry this conversion out safely with hopefully big gains. The list i have came up with will follow, and was hoping someone could offer me on advice on wether i have left anything out, something in there that wont isnt needed, or wether a specfic part is best suited over another for this conversion, and maybe even an indictaion on the cost of parts, or overall and were is the best place to purchase them (mainly from Uk to avoid dutys and tax). I hope someone can help...

Heres the list..
so obviously b16a lump and all thats needed to carry out this initial conversion
Then for the turbo conversion... a turbo (gt3071r recommened)
Turbo manifold (meutek recommened)
Custom downpipe
Big FMIC with hardpipes
Wastegate (Tial 44mm recommened)
BOV (tial 50mm recommened)
750cc fuel injectors
Engine management system
Walbro Fuel pump
ARP Head studs
at least 1.3mm head gasket (OEM recommened)
Low compression pistons maybe b18c pistons or buy forged ones, and maybe forged rods
Crank
Blockguard
Boost controller
Boost gauge
Fuel pressure Gauge
Uprated brakes
Uprated Clutch
Straight through exhaust with no cat
Cold air induction kit
Spark plugs (ngk bkr7eix iridium recommened)
Aem fuel rail
Oil catch tank
Water injection
Mayeb a B18c bottom end?

Any advice on this list would be greatly apprectiated.. At the moment i have no budget set, i just want to gather the information, on what is needed, then price out parts and carry this build out gradually, not rush into it ensure i have everything set out in my mind and be confident in what im buying can carry the job out safely with hopely big gains.. 300 350 + whp depending on the funds i have at the time.

if you cant get insurance on a vti how the hell you planning on insuring this project?
 
From what I understand, insurance in Great Britain is VERY strict. You gotta ask yourself, is the power worth it if you have to:
1.) Pay for a brand new S Class / 7 series if you make a big crash and they investigate
2.) Pay for all your own medical cost, also if you get handicapped
3.) Pay for someone else's costs when they get handicapped, all your/their life long plus a compensation
 
I understand what your saying and at this moment in time im just considering my options and gathering information, and i may decide in the end no its not worth it, and wait a few years until insurance companies are prepared to offer me a quote and then carry it out, but at least ill have the knowledge and information readily available to me down the line if i get advice now... at this stage is just an idea, may never happen in reality but its option i would consider at some stage as a build something like this is always something i wanted to do.. so i understand your concerns and many other people will have the same im sure, but id still like advice on this idea... itd be greatly apprececiated..
 
Ok, imho if changing pistons you might as well choose low compression forged ones instead of high compression B18c pistons. And too big of a FMIC will make you lose some of your boost AFAIK. But I'm no turbo expert :p

I'm no turbo expert either but i think single cams are much easier and safer to turbo. Much lower compression

D civic turbos are just as complex to install/setup as a B civics can be. D civics are NOT safer to turbo without beefing up the internals. Weakest part on a D are the rods, very thin rod that always gets swapped out for a beefier rod and lower the compression at the same time. Springs and retainers as well as a new cam will be needed.

I can go on and on about the upgrades that will be needed to a D. Everyone thinks its easy and safe, well its not. Many things need to be looked at and setup correctly to be safe and reliable.

If you can not afford insurance for a fast car, well maybe you should not have one at such a young age, 19, sheesh I can hardly recall when I was 19. OMG.
 
Why dont you use a d16z6 engine ?

Backyardracing (i think thats what they are called) own the fastest EG in uk (i believe) which runs 10s using a NON SLEEVED z6.
 
Why would you want to use a b16a and a b18c?? Use a b16a bottom end and either a b16b or b18c head unless you want to upgrade the head yourself. Don't use b18c pistons. Fork out the money and get low compression forged pistons and also forged rods. You forgot that you'll need big end bearings and main bearings. You also need new ecu and 3 or 4 bar map sensor. What ever you think your budget will be, double it. It's never as easy as you think it will. Double the time aswell for your project. All projects have set backs
 
it all bout money if you can afford to get the conversion on the way you might aswell get insured on the ek4.

as i think it will cost alot to do the engine swop, turbo, ecu, and tuning , then you'll want to change the brakes suspension etc. be better to get an ek4 get 1 oe 2 years ncb then go a head with the turbo conversion
