Noobish question. D16A6.
 

From my understanding, this is one of the best D series blocks o start with.

I am trying to decide whether to do a mild bottom build or just leave it alone.

I would eventually like to get about 250 ish WHP on the A6 wheeze. I am working with a very tight budget so:

I already have an SVO IHI .60/.63. This should be nice daily turbo that can meet my power goals fairly easily.

What power levels will I start folding the pencil thin D series rods and spitting them out the front of the block?

I assume that the ring lands on the pistons could probably withstand about 250 WHP with a good conservative tune, but if I end up building the bottom end, they will become non issue.

Also, does anyone have first hand experience with Delta's 272 regrind for the non-vtec D series? It is a cheap option, but there are some good single stick cams out there for a pretty affordable price.

Re: Noobish question. D16A6.
 

the 272 regrind is a turbo legend.

d rods pop at low 200's.. along with the rest of the internals. TT rods and vitaras ftw, thatll get you 400hp, properly tuned, with the turbo to make it to 400

Re: Noobish question. D16A6.
 

It is a good motor to start with. 250 pushing it on stock block. Just do a TT vitara build. A friend of mine has a 280 somthing and loves it. That turbo will not do to well over 300!

Re: Noobish question. D16A6.
 

ihi 60/63? cant say ive heard of that..

Re: Noobish question. D16A6.
 

Bah, that is kind of what I figured.

Translate please.

Would you like pics of the turbine and compressor housings as well?


Lol, my only complaint about Vitaras with the A6 is the retarded low compression. I guess I could mill the ---- out of the block and/or head though. Trust me, it is definitley something I have been thinking about.

Not to sound like a gay ass, but will the Delta give me a slightly lopey idle?

The other idea I had running through my head is to build a big cammed LS, but I couldn't afford to do the swap and turbo the bitch at the same time. Besides, I have been lusting after a turbo D for a long time.

;D

Re: Noobish question. D16A6.
 

272 cam will suck major balls if you run the vitara set up. It bleeds way to much compression off from a set up way to low to begin with



This has been discussed here a couple times. I

Re: Noobish question. D16A6.
 

good cam, bad engine for cam

Re: Noobish question. D16A6.
 

I understand that Chris. That is why I mentioned milling the ---- out of the head and/or block.

Just looking for some ideas.

I would ideally like to run about 9.2-9.5 static compression if I was to run the Delta cam. Would this be sufficient?

If not, then I guess I'll just have to run some SRP pistons. I might end up costing about the same by the time I pay for the added machine work.

Re: Noobish question. D16A6.
 

just get the pistons, do you really trust the machine shop?

Re: Noobish question. D16A6.
 

Who What?
Im gonna run delta 292 with my vitara setup?

Re: Noobish question. D16A6.
 

Yes. I have two local machine shop that turn out some pretty nice work.

I would only deck the block enough to bing the piston to head clean ace in check then mill the head more to get he combustion chamber siize in check.

I have hear of guys milling PR3 heads down far enough to get quench pads similar to the P72 heads, but I don't know if I really want to do that. I would imagine that the deck thickness would be getting awfully thin on either a B ore D series head for a FI application.

Re: Noobish question. D16A6.
 

weld your head chamber get them remilled for ubar comression, 10:1 and a good tune = sex with a std free hooker on 2 for 1 night

Re: Noobish question. D16A6.
 

Lol, that ---- isn't cheap. Unless I am mistaken.

Re: Noobish question. D16A6.
 

dont go with vitaras and a 272. i hate it. on chris' advice im going back to stock cam when i have some time to rip it apart. get the srps and then do the 272 cam. not such a crazy low C/R

Re: Noobish question. D16A6.
 

:l

Right, you are running stock deck height as well as stock head deck thickness. I understand that running the Vitaras with a Delta 272 would suck balls. I am not new to engines. I stated earlier what I have though about doing if I were to use the Vitasra pistons.

Re: Noobish question. D16A6.
 

Fjt is coming out with some longer rods that would bring up the cr with vitaras. BTW like I said before anthing over 300hp with that turbo wont really happend it just can't flow enough.

Re: Noobish question. D16A6.
 

i had my head milled a fair amount, and im running 76mm bores, which according to fjt bumps compression by a half point or so. but i guess if you have it planned out go for it.

Re: Noobish question. D16A6.
 

Interesting. Any idea how long before they are set to come out? I always thought about having the crank offset ground, but I really don't have the balls to try that. I keep hearing horror stories about Honda cranks that have been ground. It really doesn't make sense to me since the crank journals should never touch the bearing surface. :-\

Lol, I thought that is what you were trying to to say, but I wanted to make sure. I don't plan on trying to puch this turbo to 300. If I finally get to that point, then I will upgrade to something like a 60 trim T3T04E. That one should suffice for anything I would want to do with this build. I wish I would have kept my HX35. :3

How much did you have milled off the head?

Re: Noobish question. D16A6.
 

i cant say off the top of my head, no pun intended. it was the max that the guy suggested i should go. i want to say .20 if that makes anysense?or .020?

Re: Noobish question. D16A6.
 

Probably .020"

I was thinking .020" off the block and the head.

Heh, after some digging around, I have found that the actual dome volume of the Vitara pistons is 15 cc.

:S

Re: Noobish question. D16A6.
 

Vitaras don't have domes, dumbass.

Re: Noobish question. D16A6.
 

Excuse me, the dish is 15 cc. I guess that one could have slipped by if I had said inverted dome. I had been staring at compression calculators into the wee hours of the mooring.

:1

---- it, I am not going to use Vitaras. It looks like the best way to achieve my goals is with SRP pistons.

Re: Noobish question. D16A6.
 

+1

Re: Noobish question. D16A6.
 

Vitaras will do it, just pm Fjt about the rods. They will be a bit longer to bump comp.

Re: Noobish question. D16A6.
 

Meh, I guess I would be better off financially in the end by going this route and just using the stock cam.

:-\

Re: Noobish question. D16A6.
 

If you had longer rods wouldnt it hit your head? For the price of the rods I would just turn up the boost a little more

Re: Noobish question. D16A6.
 

No, the compression height on the Vitara pistons is about 1.3 mm shorter than a standard D series piston. The special length rods are to close the gap between the piston and the deck on a Vitara build. IT is a great idea, but the dish on the pistons is much larger than previously thought.

Re: Noobish question. D16A6.
 

i would look into cost on the rods, it may be cheaper, and more reliable to go with srps and some normal h-beam rods. vitaras are still just a cast piston, where as srp are forged. and d16 h-beams are everywhere used, for cheap.

Re: Noobish question. D16A6.
 

Damn you! Persuading me to continue with my original train of thought.

:P

Any good places to find a good set of D16 h beam rods cheap?

Here's the tentative plan. Just thinking aloud, so to pseak.

-SRP pistons with a 6.6 cc dish.
-Eagle or most likely TT rods.
-Stock Y8 head gasket.
Mill the block 0.015" this will put my pistons to head distance at about .041" right about where it should be.
Mill the head about .010"

This should net about 9.2:1-9.3:1. Right about where I want to be.

Re: Noobish question. D16A6.
 

Tunertoys.

I didn't like my vitara/Delta 272 either, I'm going with a Z6 head next season. The 272 pulled up top like a Z6/Y8 cam does, nothing super special and it was a pretty big dog down low.

Re: Noobish question. D16A6.
 

272 grind is meant for all motor madness really. If you want a grind go with the 257 or 260 grind they offer



Also port work will help on boost alot more than a cam will. Also a mucho throttle body like a 70mm :) will give ya increased top end without killing the bottom end like a large cam will with no compression.

Re: Noobish question. D16A6.
 

I'll definitely consider the 260 grind.

Port work is definitely in the plans.

Any tips for a basic port on the A6 head Chris? I would assume that the basic bowl port and short side radius would do the trick.

Re: Noobish question. D16A6.
 

hog the ---- out of it :)


get rid of 55mm piece of ---- throttle body. BUy a 70mm tb from your favorite mod :)

Re: Noobish question. D16A6.
 

;D

Haven't you had one for sale for a while now? :l

Chris, I assume that I would either have to go with a Skank2 manifold or cut the A6 up and make it work with a large TB. I have seen pictures of an A6 manifold that had the plenum vilume enlarged and an new TB mounting surface added floating around.

Re: Noobish question. D16A6.
 

I have sold like 10 of them in the last 2months on here :y



Um a z6 manifold will hold a 70mm tb you just have to weld up the iacv port



or go with any aftermarket unit. Or even better go box plenum

Re: Noobish question. D16A6.
 

Thanks for the guidance man.

Do you literally mean hog the ---- out of the head? It is an A6 head after all and I will be using a spare head to do all this with.

Re: Noobish question. D16A6.
 

yup the wheeze ripped pretty solid with the uber ports.
