DC2R build advice

[Karl]

upgrade ecu ?

Got 6 more kw at peak with tune. But power increase was alot more mid range!

[lDeVillish]

Its a 1.8 litter. Having 160 or so kw atw is impressive.
Without forced inducting your not going to get huge numbers out of a 1.8L.
Want the car to faster. Suspension work. Weight reduction

i was thinking of getting the stroker kit and upgrading to 2litre, or using a b20 bottom end with b18c head. Allthough i've been told that the b18c bottom end is a lot stronger than b20, What's your opinion on this. Also how much power would I stand to gain by these two options and which would be better i've been on google for hours trying to find info re the stroker kit and b20 bottom end options although i haven't been able to find anything very usefull....

oh the car already has a light weight flywheel an brass button clutch very responsive also thinking of using itb's though i don't know much about them haven't found any usefull info yet either.

Make car lighter eg. weight removal. Lighter rims. no rear seats ect.
I think Tinkerbell runs a moded B20

Id go k20 or K24

that's what i'm not sure of the stroker kit or b20 bottom end, which one do you think increases more kw ? the b18 bottom end i think it's stronger than b20 too.

i was previously running 114kw atw with mugen cai toda headers and t1r exhaust

[Karl]

Stiff mounts. Tune using 98 octain and lower vtec to 5G rpm.

I got 128.8kw with I,H,E, high flow cat and tune.

Personally i think a better wheel tyre compo had the best improvement.

i was thinking most kw's on the dyno for a dc2r b18 in aus.

I personally don't think you'll be able to achieve this goal due to your 15K budget and lack of knowledge/experience. IMO you should try and consider what will give you the most gains for the money you are spending. I think you'd enjoy the car a lot more if you put a K20/24 in it, with supporting mods. And sell the B18 for extra funds. It's already been asked a few times but what do you want to use the car for mate? Street, bragging rights, track, drag??? You need to figure this out first and work from there. I don't see the point in just trying to build a powerful car if you don't know what your going to use it for. Not trying to bring you down mate, just trying to guide you in the right direction. You need to try and get it right first go so you don't waste all the money your spending!!!!

i'm aiming to simply build the most kw's for a street legal dc2r how much is the k20 conversion that's going to be more expensive then keeping the b18 and modifying it isn't it ?? it's going to cost me around 5 grand just for the k20 roughly

[Karl]

street legal. Any mod is illegal. If all youre doing is chasing Kw number's. Low compression motor and high boost.

[lDeVillish]

how is any mod illegal ??

[T-BaGGeR]

90% of common mods are illegal if you don't have a engineers cert. That engineers cert is going to eat into your budget and time of you want to reach your goal.

Changing the head unit and speakers isn't illegal...... Yet. Do you need an engineers cert to okay the wiring of the head unit and speakers? I guess it could be a fire hazard?

I'm not sure on the exact costs mate as I haven't looked into it enough, but as said if you go for a K24 you should be able to find one under 1K. I was more leaning to the suggestion of doing a Frankenstein, by buying a K20 head to put on a K24 block. This is what I would do in your position because with bolt ons and a tune it will give you good power and torque, more than enough for street anyway. I don't think it's worth going for a max KW's engine build if it's just going to be used in a street car, because there is nowhere you can use the power legally. If you were going to be looking into tracking/draging the car it might be a different story. But if you are adamant on making big power, as said above you put a big snail on it, low comp pistons and forged internals.

how much power can I make out of the k20 ?? I don't know to much about k20 motor actually

this would be a good start

[Karl]

Around 180 if staying NA. Honestly Look into a good wheel tire compo.
Being FF. they lack traction off the line. Run some nice wide semis and you should be running alot faster. especially on the drag strip.
Kw don't mean crap

Its The ET and ET MPH that shows a cars performance
