If it doesnt go quicker after turbo, get a refund lolol

having vtec doesnt make much difference if you have a turbo

is there any way that i could put the front mount ON the engine or does it have to be at the front ?

Yes. Though obviously you are going to want to run a modded bonnet.
May I ask why you want to topmount though? Response?

Fair enough... however the bonnet having a buldge and a form of scoop will already attract them.... not to mention the usual 3" exhaust system that accompanies a turbo setup.

I find it pretty sad that people choose to mod their car based on what the police *might* think about it. Keep the mods legal and your driving the same... and they have nothing to pin you for.

If it is for 2 years, drive your car as is and then change car in 2 years time.

from what i have heard (i could be wrong) the biggest advantage with turboing a vtec engine is that typicly vtec engines have a higher rev range.
the actually vtec doesnt make a difference.

thats just what i have heard...never had personal experience with turbo hondas. so flame away if i am wrong. :P

nah vtec makes a big difference from personal experience you feel boost come in then vtec as well it all comes down to how well tune the car actually is will depend on how much power your car will make onli down fall is that when vtec comes through it dnt feel as rough as it does N/A

mate, by the time you turbo your civic, all the work your putting into it, and the big dent it will leave in your wallet, you have to ask yourself if it is really worth doing.

I know, at the end of the day, no matter how much money, time and all the rest you do to it, you will eventually lose the money you have spent on it.

Personal opinion, if you are going to sell your car in 2 years, i would bother turbo'ing it.
Wait until you buy a car which you plan to keep for a while, mod it over time (don't rush) and make it how you want it, without a time limit.

Also, If your worried about driving your car with cops pinning you, then you shouldn't be driving it. If your going to get booked by a cop, you'd want to hope it is something minor, because the amount of BS you have to do to get your car roadworthy, is ridiculous.

its not only people in ur car u need to worry about, its pedestrians and people in other cars.

Many car accidents (caused by p platers) are those which endanger the lives of other cars, not just the P plater.
I am on my red Ps, and you have to know your limitations and your surroundings, e.g. dont speed in shared traffic zones, or school zones, or jst neighbourhood streets in the afternoon or at all really

Anyways

Its not just as easy as wacking a turbo in.
You'll need heaps of custom parts which will cost $$$ to get decent power.
Also if you have to consider brakes, gearbox, and depending of the condition of the engine possibly a rebuild.
U mite as well drive the car for 2 yrs sell it then buy a turbo charged car and with all the money saved from not turboing the civic you can work it then and build a beast.

Will a non vtec civic go hard with a turbo ?

steve88
20-01-2008, 11:20 PM
yes, any boosted engine will go hard. D series are great but they only redline at 7500 without heavy mods to the internals, unlike boosting a B series that'll redline higher, but at the same time a B series + turbo = $8k ~ whereas D series + turbo = $3k

It won't go hard without a vtec. I have a friend who installed 2 vtecs on his engine and it made the turbo spool faster because of the air/fuel ratios.

there are a few d series motors that are running 9krpm redlines on stock rods and crank. it doesnt really matter how high you rev your engine tho, its all pointless added stress unless your motor actually makes power that high.

if you're turboing a d series, head to www.onecamonly.com or www.fjdistributors.com for fj distributors. they sell an all motor kit which includes vitara pistons, head gasket, every gasket and seal, water pump, bearings, etc. required to run a turbo setup safely on a d series motor. they also sell valvetrain upgrades that should help, and its all relatively cheap. good thing about turbo-ing a sohc non-vtec motor is that there are less things that can go wrong, which is good if you dont have a bottomless wallet.

just dont get a ebay turbo kit, unless you have the money to modify the kit so it actually works. most people complain saying that the bolts and flanges dont line up, piping isnt round, etc.

aside from that, good luck and have fun.

If your going to turbo a honda, would probably want to do it on a non-vtec engine, the compression is a lil lower, this makes for safer boosting.

One of my mates runs 4psi on a vtec engine and it pulls away from the wrx's. with the compression so high, it limits the amt of boost you can run safely.
another has 72k in his engine bay, runs low compression setup and went past a gtr sideways!!!
Bottom line is, hope you got money for tires!!! it be a good investment to get a lsd, otherwise you'll chew thru your passenger front tire every month.
Top mounted intercooler v front mounted inrecooler
the front mount has the superior performance, a top mounted has faster response times because it has less piping pressurise, however heat tends to rise, and can easliy turn your intercooler into an inter-heater.

Get your camera and take some photoes :)

^Azkik is right.

With NA engines, ad especially b18c7 engines - the higher the compression the better performance. (11:1 is b18c7 i beleive?)

Running excess boost with this compression will lead to internal issues of your engine.

Deans dc2r-t is a turbo'd b18c7 running on safe tune of around 6psi? and he wrote in his thread about the advantages of the boosted b18c7 vtec engine.

The lower the compression of your boosted engine, the longer it will last.

All I can say is never run a turbo on a HIGH compression engine. your engine will blow. If getting a turbo rather engine conversion it. Honda engines with out vtec and turbo engines without turbo, Honda engines without vtecs are still faster.

Correct meif im wrong.

You've got me confused on what your on about. High compression engines do not have a problem with boost so long as you can keep the intake cool enough not to effect the total static compression.

If there was an issue my stock b16a an Deano's b18c would have blown up already. Both are making healthy power with stock internals and stock high comp motors.

Try this link
http://www.hondatech.com.au/forum/showthread.php?t=399

The reason why manufacturer's lower compression is cos they do not run proper cooling (look at their little intercoolers) all the time and so to save the life of the engine they lower the compression.

When you build your turbo you will take this all into consideration.

There is a reason why hi-comp engines make more power boosted than the same engine with lower compression. That is cos the engine is more efficient at higer comp. The main problem you have is heat issues and combustion

lowering compression helps a little since the turbo is already compressing the air a lot, but fuel still needs to be compressed. and theres nothing wrong as long as the motor can handle it. from what i know, high compression helps spool up the turbo faster.

What is high and low compression to you guys?

SeverAMV
06-02-2008, 09:50 AM
imo, high compression is anything >9.0:1, and low compression is <9.0, and i consider the >10.5 you'd find on most new honda's to be ultra high compression. but thats just me.
you might be playing around with the iggy timing and sparky temp for a while if you have a high compression turbo build, as the mixtures will have a greater tendency to ignite earlier and ping with the added stress of a high compression motor.

Why is everybody making this so confusing, you can turbo your vtec engine if you like. you will be limited to low boost levels(for engine safety reasons), between 4 - 10 psi. This is because the vtec engine has higher compression levels then the non-vtec engine. if you have the non-vtec engine then you can run the higher boost levels.

The intercooler chills the air which helps make it less likely to ping, if you have a problem with detonation then you will burn a hole in the pistons, if you over boost you are more likely to break a rod.

Once you have purchased the car, is probably not the best time to think about going turbo or not, this is generally something you decide befoer you purchase. Simply because the purchase of a non-vtec car is cheaper then purchasing a v-tec engine and then changing the internals to increase the boost.

hmmm one other alternative is get a really thick head gasket to drop the compression a little bit.

SLOWEGG
10-02-2008, 06:59 PM
So you're saying if you turbo a non vtec motor you can run more boost? All the stock dseries turbo i see all run about 10psi same as a vtec motor.

no. its about the compression ratio v the amt of boost....
high boost + high compression = disaster (unless you've built it solid)
high boost + low compression = good
low boost + high compression = good
