I just thought i'd throw my setup in here, maybe get a few opinions as to what I should do, things I have done right, things i've done wrong, things I should do, shouldn't do, etc.
And if this part of the forum is like the rest, (kinda hopes it isn't) probably get a good flameing along the way.
Anyhow, Some of you may have seen my car, either here, or at a meet.
It's a 94 VtiR Prelude. H22a of corse. And most people think it's far too rice.
But you can make up your own mind.

Now this is what i'm doing....
I have 2 other projects I need to work on. So I just want to get this girl running and relyable on stock internals for the mean time. in the long run, I will be doing the internal work, but that will be after i've made some good progress on other projects. (A 92 JDM Si Vtec prelude and a 89 JDM EF6 CR-X)
Anyhow, Back on topic. the turbo set up goes something like this.....
H22a with stock internals.
This motor has already got 249 XXX km on it, but has always been well
maintained. Last major service was at 235 XXX when it recieved the usual
water pump and seals etc, as well as a Greddy timing and balance shaft belts.
Also, I threw on a set of Skunk2 adjustable cam pullys, and in perperation
for this build, a Koyo 56mm aliuminium radiator.
On a side note, I also recently threw in a stage 4 6 puck copper ceramic
cushion button clutch and matching ductile iron pressure plate.
And a single peice chrome molly 11.5lb fly wheel.
Custom stainless manifold.
I had this built by Richard, at Autosport Engeneering. (Yatala QLD)
I had looked for someone to do the fabrication work for a long time,
and he came highly recomended to me by Matt Stone. (the V8 Super car driver)
Richard had spent the last decade working for Dick Jonson Racing, but beforthat
worked for Ferrari, building their race chassis for Le Mann, and also built turbo
manifolds for Big CC, who specialised in turbo charging Hayabusas.
I wasn't origonally happy with a few of his ideas, but I let him have his head
and i'll save my judgment for when I see the first graphs.
The work included, a custom manifold, stainless with backpurged welds,
port matched runners with no tight bends. (his idea) a 3 inch dump pipe
with seperate chamber for the waste gate. keeping waste gasses away
from the exducer. 2.5 inch hot pipe, and 3 inch cold pipe. also a 2.5 inch intake.
T25/28 turbo.
The exact specs on the turbo are as follows.
Dual ball bearings,
Inducer/Exducer 54/71
Compressor, Trim 56, A/R 0.60
Turbine, Trim 76, A/R 0.86
I don't know that much about turbos, (which is why I started this thread)
So opinions on this will be appriciated. (I am open to changing the turbo later,
but it will need to stay in the T28 family to make swapping easier i believe)
Liquid to air intercooler.
I had decided I wanted to go with a Liquid to air intercooler set up
right from the word go. (just to be different)
Intercooler specs as follows.
2.5 inch I/O, core size 3.5x3.5x9.5 inch. (this seems very small, but i'm
assured that it's plenty big enough for this aplication.
450 cfm, Max pressure 70 PSI.
Bosch electric water pump, 16x12x1 inch PWR heat exchange with electric fan.
Turbosmart 34mm dual port BOV.
Buying the Kompact style, and for the most part, will be running it as a
plumb back.
RC 650cc Injectors. Self explainitory.
Walbro 255 lph fuel pump. Also self expainitory.
Hondata S300 ECU.
Using the Hondata to control boost, fitted and tuned by 101 Motorsport.
Here are some pics,
Motor just before I start fabrication.

Custom manifold.
The head flange and the merge collector.

And the finished manifold.

And the entire setup, manifold, dump, hot, cold and intake pipes.

At this stage, The plan is to finish plumbing oil and water to the turbo, water for the intercooler, BOV, ECU and tune. then i'm back on the road.
I am wanting advice, anything I have missed. things I have done which I shouldn't have?
Things I should do, but haven't mentioned.....??
