dang ... I guess I've gotta explain some stuff about the D again .


for 300WHP D you need:

hone the block - 100
vitara pistons - 130
Eagle rods - 300
OEM bearings - 80
ARP headstuds - 100
new OEM headgasket - 50

alum.radiator - 250
clutch - 450
custom exhaust, 2.5" or bigger, no cat - 400

-T3/T04 50 trim. The 57 one is a bit bigger. And .63 exhaust housing to support up to 30psi of boost - 500
-nice manifold - about 500
-downpipe - 150
-38mm Tial wastegate - 250 or so
-FMIC - 250
-charge pipes - 100
-BOV - 150
-OBD1 ECU and conv. harness, chipped with Crome - 200
-tunning - varies a lot. If you're good, borrow a wideband from a friend and do it yourself .. or buy a wideband - 300. If not, than pay ~500 for the dyno tune
-injectors - nice RCs are 300, cheap DSMs with resistor box are 50, precisions are 200 or so as well
-map sensor - 30
-boost gauge - 60

Total: ~4700 , including nice RC injectors and 500 for the tune

and that's close to 400WHP setup. But most likely 350WHP or so

you don't need Golden Eagle sleeves, aftermarket intake manifold, head porting, integra TB and such ... Throw in a Zex cam if you insist, it's like 250, and aftermarket springs if you with to rev up to 8K RPM

and yes, go to www.turbod16.com to see what's going on with the D series

if thats true, then you should have built halfwits.

saying that setup is good for 400whp is not true im sorry. Ive said it 100 times, the TURBO D world is INCONSISTENT. There are guys with bone stock motors making 300-330whp, then there are guys with BUILT motors, sleeved blocks, and headwork, barely making 320whp.

Halfwits made 285whp @18psi on a stock head with the turbo you listed and a TDF manifold.

400whp is nearly impossible to hith without an intake manifold, headwork

there are guys with Turbo Ds that don't have a clue about what's going on, and they make not much power. Then, there are guys who know some stuff, and make tons of power with cheap setups.

I don't know Halfwits car, but if he made 285@18psi, what do you think he would make at 30psi ?? I'm gonna guess first - for 18psi he gained ~180WHP, so that's like 10WHP/psi ... so that would be a total of 405WHP @30psi, give or take 15 due to the IATs

400whp is nearly impossible without aftermarket IM and head work, but yet it always pops up someone that has done it, and his/her car lasted a lot more than 1 hour: http://honda-tech.com/zerothread?id=1719843

ive seen that thread and i dont believe it when he lists:

stock z6 head
stock z6 intake manifold

At 30psi on stock sleeves, bad things happen. So hes saying that with a more restrictive manifold than halfwits, and only 5 more psi he made 115whp .

i dont buy that sorry

he sold the car to another member of .turbod16.com, and the other guy has a fun time driving it
I believe that the stock D sleeves are very strong, and would hold up above 400WHP. The problem is that those can't witstand even a small detonation, which cracks them up even at 150WHP power range ...

there are too many guys with over 400WHP on the D-series stock sleeves and I'm gonna be one of them next year most likely Ehh, if only I had time to do work on my car ....

sorry if im coming off combative, im not meaning to, just discussin my personal experience.

When FULL-RACE PINKs car made 476whp (highest SOHC turbo i know of) they did it on stock sleeves. however they had:

CUstom camshaft
GT30R
Full-Race Manifold
Headgames ported $3000 head
custom intake manifold
springs, ret oversize valves
rods an pistons.

if they could only get 47xwhp out of it, with an UNLIMITED budget, i dont see a STOCK head an intake making 400whp, sorry. with Halfwits, we learned that the head really hits a wall above 7000rpms. I was hoping for 300whp on pump which i think is still attainable, but i dont see his stock head making 400whp and i wont push stock sleeves to above 20psi, MAYBE 22-23 with a shit ton of timing pulled out.
