I started my turbocharging days with this motor, after it continued to blow head gaskets and piss me off i ditched it for an H22..

Well years later i decided to try it again, except this time cheaper, not pushing it as hard and leaving the motor fairly stock.

I found a pretty clean chassis with a blown up, already in pieces B21A1 for 650 bucks towed it home and started tearing it apart.

got the motor out and cleaned up the bay a bit

Bought a different block, the b21 is FRM. B20a5 is normal iron, bought the b20a5 short block in pieces for 100 bucks threw down a sick hone job and bought an Ebay evergreen rebuild kit.

H23 rods are a direct swap for these engines, and there much stronger looking then stock, scored a set for free

instead of cleaning the stock pistons and risk breaking them upon removal i bought a set of B series cast nippon turbo pistons, for the price why not.. had the wrist pin bores honed to fit. Combined with the b21a1 head we now have a really low compression b20a5 ( about 7.9) spent more than i wanted on that but got the rods, turbo, and injectors for free so i spent money else where.

decided to do a quick cleanup job on the head, lapped all the valves replaced stem seals, and cleaned up the valve bowls, got the head resurfaced for free, Thanks Kyle!

motor going together

Being this is a bastard child of a motor there is no cheap cast iron china turbo manifolds out there, so i bought one for an H22a and made it work... drilled/hogged out a few holes, nigger rigged the gasket and WALA

Got an old Garrett T3 turbo off a mustang/tbird for free, had tons of shaft play but in otherwise decent shape, got a rebuild kit for it off ebay, took it to work and sandblasted it all up.. 75 bucks into the turbo

modified the compressor outlet for a normal coupler, and built a gay little flange for the air filter

Pretty much no way to fit internal wastegate with the H22a manifold which sucks so i niggered a external setup with a really chinese wastegate and recirced it back into the downpipe, thanks Columbia River Mandrel Bending for the quick shipping and awesome prices/RHMT discount!

intercoolers are a pain in the ass and somewhat of a nigger to install on these old preludes, so i stole a meth kit for 150 bucks and used the ECU to control it..

Got the BOV for free thanks NOL!
Got a steal on S300 ,already installed in a P75 Vtec and boost control ready! i know Hondata is hated around here but for 350 bucks..

Finished product, daily driving it on 10psi

All in all i have about 2400 bucks into the entire setup including the cost of the car and a new Comp Clutch

I always thought you were a fucking weird-o for liking those chassis, then I got to drive a 300whp one that was stockish suspension, and hooked power like a Civic only wished it could. I want one.

You're still a weird-o.

This should also be added with list build threads.

How close do you think on betting the A20 Accord that was there the last two years?

i like having a car that not many people modify, and there just as capable as any other honda in most cases.

nice work mitch.. my sister had the same car new back in the day. top notch work non the less.

turbohf · « **Reply #10 on:** May 13, 2013, 10:07:04 PM »

bring 2? im planning on bringing 2 cars to the meet.

ps. not sure if anyone even remembers back that far... but i use to have a white 90 Prelude Si, like Mitch's other car. i liked it. was slow tho.

flat_black · « **Reply #11 on:** May 13, 2013, 10:48:21 PM »

yeah i thought about bringing 2 cars, but its to much to worry about and to much gas.. i really wanna see what the 240 does on a dynojet, and i really wanna see what this new abortion makes as well, id guess 220whp or so.

Impressive hybrid work there on a car that you don't see on the road that much anymore. I just had one in my garage last week for ball joint swap - was really impressed with the turn radius and handling it had (after I installed the new ball joints) - of course no power with the stock SOHC power plant. Factory camber adjustment was a nice feature added to it as well if you wanted to keep the ride height stock with more adjustability.

What pistons did you use for the setup; some run of the mill nippon LS pistons?

Is this a Seattle thing?

With that much ballast in the car, it'll probably never spin.

The ballast is good for traction

Built a catch can for this turd... tired of smelling the crankcase on the way to work

Also found a map sensor laying around so it reads beyond 9.5 psi

ratcityrex · « **Reply #25 on:** May 26, 2013, 11:42:07 PM »

Looks good nig. So what's the plan for next weekend? U bringing this pig or your nissan?
