Problems on d15b turbos

There is nothing inside my engine with exception of a block-guard and 12mm head studs that is not a honda part.
Sure it's brand new from the deck of the block down, but it's still exactly the same parts as any other D16a running around the place.
There has been no strengthening in the bottom end.
I had it all dynamically balanced before final assembly which would have helped, rods and pistons and flywheel/clutch bolts are individually weight matched to within 0.5gms and the crank/pully/flywheel and clutch pressure plate were all balanced in one assembled mass with all bolts in etc.

Yes and if you can get hold of the crank and rods out of a D17a thats even better.

[thirdson]

^^sweet..thats alota work..but im pretty willing to try it aye..where bouts did you get it balanced?

and with the d15b to a d16a change, is the d16a going to be more reliable to the d15?

sorry bout the questions..still learning

Auckland Dynamic Balencers

Yes same reliability.

haha because your indian nah just kidding....nothing wrong with d series in my opinion and as with the torque from a b18cr i agree ive had an eg with a b18cr, had filter, 4-2-1 headers and twinloop exhaust with a vafc tune making 127wkw, and its damn annoying having power sky high in the rev range!! tirque was non existent down low....if i had a d id turbo it...considering turboing my b series haha

Sell your car and buy something already B18C or turbo....

Save you a hell a lot of money!

was thinking of that..but i wanna experience the d ninja first..but maybe after the d ninja might try the tegys

i had a d15b turbo eg8 sedan that was turbod garret t3 on it ran 12psi on a stock motor and raped the living shit out it for years, i brought it already done and the guy before me drove it even harder then i did, sold it and wish i had kept it really good daily driver and would clean up itr s, it was the same as a type r civic speed wise on 6psi

just my 2 cents worth

Was it black? did it used to belong to Kane? EG8T? If it was that was a mint car, real cool back in the day.

[Hayce]

^^ was a nice car, nate_dogg also owned it. I drove that car and yeah whawhaaa

[gizzmo2]

guy before me was micheal i think by memory and he built it and it was green must be a different car your thinking of

This is probably one of the most interesting threads ive read.. especially seeing as I am in the same boat as thirdson, trying to decide between b18c or d15 turbo..
Just got one question.. my eg has a d15 in it atm, done nearly 180ks, if i was going to turbo it would i need to work the bottom end? or would it just depend on what cond its in? Seems to be running ok (but then again, i probably dont know shit..) wouldnt be pushing it too hard 6-8psi probably cos its a dd.. any opinions would be wicked, or even better if anybody in aucks has a turbo d15 theyd be willing to take me for a boost in.. cos by the sounds of it you can do all the reading you want but it all comes down to experience

[thirdson]

^^^dude if you find someone to give u a lil boost on their d..let me know men..wanna ride too hehehe and when im going to turb the d im going to get the engine checked out first aye..so ill know if its worth boosting or if im going to have to cash out more money than i need..try get the engine diagnosed first aye..

and we got the same thing bro..only want 6psi..just want the thrill of having the honda boosted

Do a compression test on it to see how healthly it is.

6-8psi it will live a long life if tuned properly.

What sorta results shud i be looking for?

Turbo your car and find out

what a stupid fucken thing to say, clearly there after advice, il jump in the boat with them too as il be doing this early next year,

from what ive read and asked upto 10psi should be fine with a good tune

10psi is a good "generalisation" but you should be looking at power levels rather than boost, the more power you make the more strain you are placing on engine components i.e. you will be pushing the motor harder @ 10psi on a GT4XR vs a GT2XR. But for the average build yes, you will be absolutely fine on 10psi as long as you have a good tune/supporting mods.

How is that stupid? Hes just mentioned about turboing his D15B, nothing there about what setup hes going to use so how can we give him an accurate "you should be making XXX amount of power" comment?

You just want the cylinders to all have similar compression, I imagine a healthy d15 will have about 150 -160psi in each cylinder. Aslong as there within 10% of each other and the readings aren't silly low then it should be fine.

Get on google if you want to find out how to do a compression test, but a friend or local mechanic will do it easy.

[b16a2]

everyone is going on about how 10psi is fine or 5-6psi is fine on a stock block.
its not about what boost you run its about the power you make stock d series blocks can not handle alot more than 160wkw "reliably" you can make 160 wkw on 15psi or on 3psi depending on the size of your turbo and some other factors.

[Coupe-R]

what drags were you at last time sam??

hehe not drags, but on the road in 3rd gear get a 140kw B18CR
vs a turbo stock block D series (which should be making EASILY 20kw more)
should beat the b18cr, let alone more tq it has to help out.

Drags is a different story, too many factors.

Basically i choose b18cr for reliability and easy of setup at the track.

But yes a turbo d could be a faster car easily in a straight line.

[cowboyslayerfh]

Turns out my dizzy decided to shit itself again yesterday morn, shud be covered under warranty tho cos it just got redone not even 2 months ago! So a compression test will have to wait for the time being.

Was wondering wether any of you guys have had experience with ebay turbo kits, eg;

http://cgi.ebay.com/ebaymotors/eg-ek...mZ380070811728

also

http://cgi.ebay.com/ebaymotors/88-00...mZ220290646256

Shit those are long links, but yeah, any thoughts? Cheap n nasty? And assuming i get even and decent compression test results, what else would i need to get done with a kit like the above, aside from exhaust/tune?

[mr_tec]

i thought turbonetics kits usually go for a few more grand so maybe a cheap knockoff

and note on other one you wont quite make the 350-400hp stated just by bolting kit on

[doo0T!doo0T!]

You can still compression test with a fucked dizzy, all you need is a starter motor.

[tarmac-]

Trap speed determines which car is faster, or which car has more power. A car can be doing 15 seconds @ 170 k, vs, 13 seconds @ 150k.
