Charging a D16A9
 

hi guys (from a n00b in South Africa).

was just wondering if anyone out there has done a project on an A9 before.
I'm not sure if it is available in the US. From what I understand it's virtually identical to a ZC. The only 1600 motors we have in 4G's are the A7 - (SOHC non-vtec) which has long-ass gears which tends to run out of power before it runs out of revs in 5th (the missus has one of these). The other is the A9 (DOHC non-vtec), which I have, which has close ratios and conversly runs out of revs before it runs out of steam in 5th.
If anyone has boosted an A9, what is the ideal turbo to use? My major concern is the space between the radiator and manifold, which is virtually nothing!
Also, I read that the HF manifold comes off 91 CRXs? What motor specifically is it from? Our CRXs use an identical A9, which has a wierd stock 4-2 manifold, with a dual downpipe that goes into 1 further down.

2nd hand parts here are a bitch - and a used turbo would most likely come from a Euro, like a diesel Golf or perhaps a Renault or Saab even. Unfortunately we don't have any DSMs here besides a few rare Evo8's.

Thanx for any help you can provide!

a log manifold should give you enoguh room. also, try our fs forum for parts or even ebay.

do you have EDM cars i south africa?

do you guys have a 92-95 civic VEi? it is a d15z1 vtec-e engine (same as the usdm VX). these engines have about the same manifold as the usdm CRX HF. But i don't know how those work with the big radiator.

do you have saab 9000 turbo? those use garret t3 42/48 a/r...

Our cars don't conform purely to EDM (i think). The thing is, our Hondas were manufactured under license locally by Mercedes Benz up until 6th Gen, so some parts were sourced from Europe and some from the Asian market. 7th Gen came fully iimported from Japan if i remember correctly.

As far as our 92-95's go, there is no d15z1. All we have is a D15(A5 i think), carb-fed SOHC, D16 A7 & A9 as i mentioned earlier. Later they decided to bore out the A9 to 1800cc. It had a bit more torque than the 1600, but it didn't feel as responsive for some reason, and had a lower redline as well.

those old Saab 9000s are around, but very few and far between. My best bet is to find a busted turbodiesel Golf or Megane - I'm busy trying to find what turbo those things run.

This is true for all but 94-98 Saab 9000 Aeros, which used the Mitsubishi TD04HL-15T (T25 flange)...The older 9000s used the GT17 or the GT25

here's some food for thought...

That guy never says whether he's at altitude and whether his engine management maps boost based on measured absolute manifold pressure...

If so, the SAE correction is very, very high....
