I was talking more about the intercooler then the turbo....

well, a volvo stock intercooler, from such as a 740 or so would struggle to support anywhere near 400hp. I ran one on my old Merkur, years ago, with a Super60 Garrett, and at 24psi, I had a 4psi drop across the Volvo fmic.
and wriggled a scant 356whp using it, on a 2.3L..
edit: then it blew the plastic endtanks off!
as for your other post snippet:
but with bigger cam, porting the heads and bigger valves, upgrade chip, high flow cat, bigger throutle body, and shave the heads down to up the compression you could get around there.. without a turbo i would think...
Start by going EMS, deleting the MAF sensor, etc.
Shave the heads down? The M42 is 10:1 CR stock. you want to raise the CR for a boosted application? You ever fooled with turbo cars? It's not that you can't turbo at 10:1 CR, you just have to factor in the odds of killing it, which are high. Remember that shaving the heads also closes the proximity of the cams/crank, thus can throw off the geometry/timing. Shave enough off, and you'll be chasing your tail for awhile, trying to correct for it - if you even can. Been there, done that, on an NA motor a long time ago. Now, I deck the heads just enough to make 'em flat!
My old Civic with B18C swap was 10:1. I put a T3/T04E .60 on the stock bottom end, with EMS. The best I could safely get was 310 @ 10psi and a lean 12.5:1 AFR, and that was with 50/50 meth injection on a .7mm nozzle @ 150psi. The meth injection was the only thing that would allow me to run the AFRs that lean to make that power level. I also feel the Honda B-series motor is much more efficient than the M42; not that that's a bad thing. Just seems to have a much better B.S.F.C. than the M42, NA for NA.
I'm not trying to be a prick, but much of your suggestions in this thread are misleading, and/or way too general. If you've typed incorrectly (which happens, I know), then I do apologize.
The Volvo turbo is a Garrett-based unit (with a non-standard T-3 flange) with a .42AR compressor, and a .48 turbine housing, and flowing roughly in the 200cfm range. Hardly worth anything over 200hp on a 2.3L, let alone a 1.8.
A 400, or even 300hp 1.8L M42 would take, as previously stated, mucho bucks to pull off reliably. you're talking forged crank (~500usd), stronger rods (300), pistons(300), lower compression, big injectors (~800cc/70lb/hr, $2-300), head porting (5-600), HVHF fuel pump 255lph (100), MAS or Speed Density conversion, full EMS (600 for MS, 1500 for something else), bigger TB (200), possibly block-work, clutch set (3-400), turbo manifold (5-600), BOV + EWG (700), big, efficient turbo (8-1200), fmic (2-400), fmic plumbing (150-200), wbo2 (300), head studs (150), and more internal parts, probably ranging totals of 4-800usd..
So an off-the cuff rough pricing puts such a build around 8-9000USD, and I'm sure parts have been overlooked here, as well as tuning, at roughly 150/hr for at least 4-6 hrs..
I've went through this process several times; most recently with my Subaru WRX.
I definitely don't know it all, or even most of it, but I can tell you I've spent many dollars, many hours, and broke lots of parts in the past, trying to achieve what shouldn't be done. Now days, I tend to spend it up front, once, rather than spend less, more times :cool:
Also, as previously stated by GrindCulture, an M50 swap, even turbo'd, will be more torque, more power, for far less money, yet still have the reliability, if done correctly.
M50 working on now, in a 318is
the '69 is friggin sweet, btw!
