So im working on building a turbo single cam . my goal is is to make 200 -300 hp and this will be my daily driver


i have got a d16z6 swap coming and my first plan was to port and polish the head, port match and plane the head down .020'' . i was looking at using p29 pistons and not really sure what i should use for rods. then i was giong to look at a turbo kit .

your guys imput on this project would be appreciated for sure

The difference between building for 200 and 300 hp is a lot. Pick a number.

I whould check out bisimoto for the rods. Some people hate bisi some people love his work. If u ask my opinion he's got great products expecially for sohc

Don't use the P29 pistons. They will yield a high compression without the benefits of the forged alloy.

If his goal winds up being only 200hp then WTF will he need rods for? For that goal he won't need to do much of anything. OP needs to clarify his goals and budget before people start recommending parts. Right now this is another one of those pipe dream threads.

p29 pistons plus decking the head = too high of a compression ratio on stock internals for a turbo motor

225 is the limit for stock internals
300 will need a built bottom end

HFXCIVIC

ideally hitting 300hp would be excellent. its the cost that worries me not sure how much it will cost me .
i can see not decking the head and spending the money on rods also i was worried about my timing belt being loose because of the decking

nub

300 can be done easily with a bone stock head.

With your power goal set now you need a budget.

HFXCIVIC

1000-2000 , as i already have the motor. but the cheaper the better . this is my first build and i would like to use quality if possible as i plan to bulid off of this set up for a while

nub

By what you've asked and stated above I would assume you're going to pay someone else to do everything.

Double to triple your high number depending on your area.

at least, then theres sales tax, etc.

unless the head and block are warped they don't need to be decked, the all motor guys do it to get a higher static compression, something you really dont want on a stock internal turbo build

take it to a local shop because from the sound of it, you'll **** things up even more if you try this yourself

HFXCIVIC

wow bro thanks for the help , guess asking questions to learn is the wrong thing hey.
Guess i should only be hear if i already know all the answers? yeah thanks

btw im a apprentice mechanic .

any one that has some good insight on how to build a reliable dd turbo on a single cam that can handle 300 hp i would love to hear your input .

so far looks like im going to rebuild the bottom end new acl main and thrust bearings new H beam rods by golden eagle new rod bearings and vitra (sp?) pistons . and give the block a good hone . before i put the turbo on .

what would be the ideal compression ratio to be aiming for on this build ?

any other good ideas ?

Yeah. The FAQs. Red 'em. Build threads. Read 'em. You're not discovering anything new. Same tired questions asked at least half a dozen times in a week.

And asking "questions" isn't research, it's an opinion poll. Two different things. Stop being lazy and put in the work. You would think reading causes physical pain nowadays.

Look this kit, i fit the same on my car and the comp. is not to low.
with eagle roads and vitara pistons the comp. is verry low and u need a hiboost

HFXCIVIC

Thanks. What do you think the best compression is for a boosted D16 with a built bottom end. I would like the car to drive well in and out of boost and i don't really want to run high boost all the time.

Boost your stock motor and get a good tune. You dont need to port and polish anything for the power goal you have in mind. If your tune is spot on your stock engine should last you some time.

You need to read up more on what it takes to turbocharge your engine. By the looks of it you want to do too many things that aren't necessary to in order to simply boost your car.

I'm going to leave this here for you apprentice.

There's also another site dedicated to the SOHC that has some good info. Has to do with the series of your engine. They won't spoon feed you either though.

Nobody's going to wright you a book on what you should do, what you need or what is best, it's all subjective based on your goals, use, skill level and budget. This isn't a chat line.

As I stated in my last reply you in no way implied you had any knowlege or skills thus my answer.

If you have a specific question about a specific issue ask away.

Yea that first eBay link is what you want.. without custom length rods, the ycp's lower compression to like 7:1 which is way too low and the car runs like ****

Golden eagle doesn't make rods.... the company is called eagle and has nothing to do with GE

Anything over 225-250(max) is really pushing the stock internals.., d series have paper thin rods and they are usually the first thing to go next to ring lands. If you want a reliable 300 hp d series this is what you need

Pistons
Rods
ARP headstuds
OEM headgasket


Now you can make the setup more efficient by using a larger throttle body, different intake ,anifoldm mild cam, etc. For 300 porting and polishing the head is pretty over kill, especially if you aren't looking for more power in the future.

But a good intake manifold, larger throttle body and a mild can will make more power with less boost and you'll have a broader powerband

nub

Everything you pointed out are valid points. However this all again depends on goal, budget and use. Remember the OP stated a 1-2K budget. For the stated power goal all of the top end mods are not needed and money spent. A properly built bottem end with a totalty stock top end can easily meet the power goal with a properly sized tubo and tune. 1-2K just isn't realistic. Just the machine work on the block and purchasing pistons and rods will bust 1K depending on what a machine shop in his area cost.

I'm talking goal vs budget.

If you've boosted before then you know the cost adds up with all of the little things. So say he's 1K into it and all he has is a machined block and a set of rods, pistons and bearings. Linked add doesn't say anything about rings. How about a full gasket set? What about clutch and pressure plate. May need a flywheel depending on the condition of the existing 18 or so year old unit. What about the tubo "kit"? None I've seen are "complete" and always reguire something more. Some depnding on quality reguire fabrication or modification. How about tuning? Going to need something programable and someone to tune it. How many builds go flawless from start to finish without making mistakes of some sort.

I'm just trying to say the budget will need to get bumped to meet the power goal. Unless you're going 1996 tech with RHMT, missing link, fmu and vafc. He said "quality" and "reliable".

Yep, take your initial budget and triple it... because by the time you get all of the needed parts and all of the little details and nit picky **** taken care of you still need a tune.

Julio@Bisimoto

Wow, a lot of back and forth. Building a reliable daily driven setup with big power can get very costly. If you cheap on from the get go, it will cost you much more on the long run when you start replacing parts...

My opinion if you have a healthy stock engine, invest on a good turbo setup, engine management and tuning. If you plan on building your short block, I recommend forged pistons and steel H-beam rods which would be much more reliable than cast pistons. Hit me up, we have a few specials going on right now that are much cheaper than retail!

Cheap
Fast
Reliable

Pick two because that's what your build will be

300 on stock z6 internals is doable and safe .just need a tune.
