D16A6 needs a kick in the ass! - Kaan - 10-15-2004
I recently went on a little spending spree. I've got my freshend up D16A6 in the car... with ZC pistons and Apexi S-AFCII sitting on the floor in my room. I've been tempted to run the D16 high compression with an exospeed built head.
BUT
There is a couple guys at work... and one in the club... that think i should boost it. there are plenty of kits out there... there are "kits" with just the manifold and turbo and i finish the rest.
Now all the being said. I still want to track the car. I dont know if b00sting a car will really hinder it on track... or increase maintence that much since i alreayd stick stricktly to the 2.5k to 3k oil change. so what do you guys think... high compressioni or b00st?
with all that being said UPS confirmed delivery of a little bigger suprise :twisted: .... a B16A2 head with no cams, ITR everything else. now i'm looking for an JDM ITR tranny and an EG i think...
I've been spending money like its going out of style... and i'd like to tap into the "wisdom" of MM... for encouragment... and a kick in the nuts reality check!

sounds like you need to do some soul searching... you have 3 options up there, 2 of which are totally different directions...
- .RJ - 10-15-2004
You sure the b16 head has ITR rockers/LMA's/springs? Better check, because its easy to say that in a f/s ad, but who knows the truth....
Anyways, if you do get a JDM ITR trans, try to pick up the USDM ITR 4th/5th gears, the JDM 'box has the same 4th/5th as USDM GSR. You could probably sell the B20 bottom end and build up a b16b-equivalent short block if you wanted to go that route.

Boost it! Home made turbo has boosted, like, 80 million D blocks. He practically has step-by-step instructions.
- Kaan - 10-15-2004
i'm pretty sure it has the ITR stuff in it... i only paid 400 for it though... if it does its a steal if it doesnt its still fairly cheap for a head without cams from what i've seen. as far as going in 3 different directions, the plan is to have two cars... both basically trackable/wreckable cars. the crx and an EG. i like the idea of boosting the A6 but then again i dont wana blow it up :roll: ... going high compression or boost... pushing them will cause reliability issues. so i wont go all out with it.

why?
- Kaan - 10-15-2004
because if i blow one up i still want to be able to track one. i have NO need for a comfy daily with leather and all the other crap. i dont need more than 2 seats.... i dont want more than two seats... unless i get a truck. IF i get married let her drive the 4 door piece...
its a personal prefrance.
- BLINGMW - 10-15-2004
you know my vote. Forget boost! I'd rather have a simpler engine bay and better reliability. I don't know JDM this and B16A1A666, but if some high compression, trick head setup will make enough power to have some fun, that's the way I'd go.
- Kaan - 10-15-2004
one of the biggest pros for b00st on the A6 is i can buy stuff here and there and get it together over time... because going high compression is going to breaking the motor down alot. well head off oil pan out... car on lift. either way i'll have B and T do the install... they are primarily a b00st oriented shop... except when they were building 3 sccs cars ... the all motor crx... ok so they KNOW b00st and everything else. i might stop by there and see what thomas says.

as much as i love boost, when you're at the track you don't want to be looking through a rat's nest of vacuum lines and dealing with the huge heat a turbo makes/cooling issues and there will always be lag....
that B16 head will flow awesome as it is, just take it down the NA route and enjoy the natural step up in power from your previous engine. this is not to say a boosted engine wouldn't be solid on track, its just that simpler is usually better.

i dont want to boost my B20 vtak build 8) i want to boost or high compression the D series pile in the engine bay!

oops. well for a small little D....boost wouldnt be so bad i guess. the D is sohc, right? and i take it you can't rev it too high, right? in that case, boost would add in nicely at maybe 6-8 psi. but then you have to resist cranking the boost controller for that one extra psi.....

hot man pirates!

i missed the hot man pirates i guess... damnit! i'll have to visit RJs mom so she can explain

Boost is as reliable as your ability to resist cranking it. The term "Forced Induction" basically tells you that you will be stressing the engine parts, however, the nice part about a turbo is that you're only stressing things when you're boosting. When you are idling, driving around town, etc, you're not pushing the system hard. When you get to the track take the boost to 50-75% of what your engine can handle daily and you will be able to make it through countless events without trouble.
Another nice thing about boost is that you're blowing the pistions down when they are on their intake stroke, as opposed to pulling them down on a N/A engine. Rods are strong when squeezed, but not pulled, so if you are really pulling high RPM's on a N/A engine, they are changing direction every fraction of a sec at over 80 miles an hour (according to an engine building book I have.) With FI, the rod doesn't have to pull as hard because the cylindar is having air "forced" into it.
If you get a nice turbo (good tolerances, oil and water cooled, 360 deg thrust berrings, etc) it will be good for many many miles. Also get a nice intercooler, it'll reduce the stress on your turbo and require less psi into the engine.
Semi's need power and reliablity, and they are turbo'd. Powerstroke Diesels are turbo'd, and it's the most reliable engine in a full size truck. Granted they are also Diesel, but still, 500,000+ miles on a turbo engine.
It sounds like you're building a strong block, and so I see no reason for you to have trouble. Turbo's have developed a bad rep because yahoo's slap one on their stock engine and crank up the boost for some short term gratification. Stock N/A parts can't handle boost. Stock turbo parts can't handle a "lot" of boost (<--experience here).
I'm a turbo guy. I say turbo it. Just use good judgement when picking psi.

i'm not building the bottom end for the turbo application. but i dont plan on using anything more then 6 psi becuase i know i'll blow the motor. i figure a fresh stock bottom end can handle 6 psi.... reliability with a turbo i understand...................... but if i'm going to get back in the bottom end of the motor i'm going HC.
- Mike - 10-15-2004
i think the money spent for a measly 6psi (what would that give you? 40hp?) is much better spent to get the car more track-ready... rollbar, harnesses, seats, suspension, bolt-ons, wheels...
