Looking for 5-6 psi for my DD

[Jedz123]

So I've researched around and it seems everyone is all about building their motors up and trying to hit 15-20 psi. how about guys like me that only want 5-6 psi to improve the ride of their daily driver. I've been looking into IHI turbos off older Subarus fast spool time and low boost. I know how to build and tune power getting turbo cars (owned a 90 Dodge Daytona 2.5 T1 with 190whp @4800 rpm and 285 wftl/lbs@ 1500 rpm) But I don't want to build another turbo power house. Just want to enhance my daily driver. Good idea for me? Is it easy to do with just 5-6 psi? I am good with my hands and metal so no worries about fabrication I think I can handle anything a project like this throws my way.
Thanks guys

well from what i have read around reaserching my own build, these engines are good at holding boost on stock internals, people say you can hold around 10 psi with a healthy engine, if its not running to par stock, just do a stock rebuild, no expensive aftermarket pistons or valves. so from what i have read 5-6 psi could be done easyly, still need to get a tubo manifold made,switch over to OBD1 or atleast a stand alone fuel management system and of corse fit your charge pipeing and ediquit exhaust, someone correct me if im rong

[russiankid]

Before you do anything, do a compression and leak down test. I remember reading that if your compression is lower than 150psi, don't turbo.

[ghettogeddy]

well your gona half to make your own turbo header no matter what lol unless someone puts one up for sale sometime soon lol

[MessyHonda]

justin86 still has a turbo kit for sale.

if your decent at fabrication you wont have any trouble. The trouble you will have is fuel and ignition management. Its a good idea, read up on OBD-1 swaps

[bobafett]

yeah like the others have said, you will need to fab up a manifold, downpipe, charge pipes, wg dump etc...

for tuning if you are never going to run more than 5-6psi you could probably get away with an safc and btm. you will probably want a 190lph fuel pump though and some dsm 450cc injectors.

wow there's a great start

[Jedz123]

thanks guys you have all been a real big help.

I only got a few Q's so here they are:

1) For an OBD1 swap what in the hell do I need? Do I need to swap everything out or just the ECU (orECM)?

2) BobaFett you said I could get away with an SAFC and a BTM. I know what a SAFC is. What is a BTM?

3) I'm able to modify anything for this mod. Exhaust you guys are saying I need to upgrade to a bigger exhaust system. What size piping should I use what type of mufflers, cats, resonators should be on the pipe?

..I can't think of anymore...off to work.
Thanks

not trying to rain on the parade...but it looks like you have an auto...id probably research how well the auto trans would hold up to boost...

it wouldnt. Driveplate would pretty much shred if the gears dont go first...

[bobafett]

MSD BTM is a device that retards X degrees of timing per pound of boost. You can adjust the dial to pull more or less timing based on your setup. It's a pretty sloppy and unsafe way to control timing, but unless you do an obd1 swap, thats the only way you can retard timing. One of the downsides of trying to mod an old obd0 accord.

As for exhaust, once you are boosted, the general idea is the bigger the better. 3" is probably fine.

As for the obd1 swap, do a few searches, the steps have been documented pretty well, but its a bit scattered.

The bottom line is: need obd1 ecu, modding a obd1 distributor to fit our head, some wiring from the electronic dizzy to the ecu, an obd0 > obd1 adapter harness (repinned by you cause it won't work off the shelf), and you have to solve the VSS issue which can be tricky. its sure not simple, but its not insurmountable either. there are about 5 members on here who have experience with the upgrade.

but I would be nervous about boosting with the auto tranny. they are notoriously unforgiving as is. so you might want to consider a 5 speed swap too.

bobafett i used a OBD-1 PR4 Ecu and i did have do any thing to the VSS even the speedO is right on my dataloging.Maybe the PR4 is some thing to look at for going OBD-1 non Vtec and it uses a P30 base.The differenc i can find between the PR4 and the P28 is that the PR4 is bitch to convert Vtec.

[bobafett]

interesting. most of my research has been on a p75 non-vtec integra ecu. sounds like the pr4 might eliminate one hassle!

It was nice not to mess with the VSS

Wow all that with only 5 psi... I shouldn't even beat on it huh?

If a transmission swap is in order, then I'm out thanks guys!

swap is actaulyl pritty easy
takes about 30 mins to get the out out
only hard part ive heard is the pedals

[Jedz123]

I just swapped this

I'm swapped out for now thanks...

[snoopyloopy]

so tranny swap should be piece of cake and if your pockets would allow you too, talk to guaynabo and see if you can't get a manifold through him from the guy who made his. that thing is beautiful.

[Jedz123]

....how to people talk me into these projects..

How much do you think I could get my hands on a manual tranny for my car???

If it's less then a grand I'll consider...

Damn you guys!!!!!

[bobafett]

I bought a 5-speed tranny at junkyard for $75 but had to pull it myself.
Factor in the cost for a flywheel and new clutch etc, and pedals, and you should easily come in under $1000 even with a really nice clutch setup and all honda parts.

[Jedz123]

don't I need the ECM as well?

[bobafett]

not sure, couldn't hurt, and they are bound to be reasonably cheap. i have an extra 89 5-speed ecu i can sell you if you don't want to go find one.

but if ur planning on doing obd1 as well you don't need to worry about the accord ecu. however if it were me i would try to get one project done at a time lol.

[2drSE-i]

ya if this is your DD i would do the five speed swap and get it running before you attempt your turbo swap. if you try to do it all at once you will run into problems and the car will be down for weeks lol
