Whats up guys....first post over here, i'm a regular over at HondaCivicForum.com, but my suite mate here at college offered me his Prelude for $4500. I've got a 99 Civic Coupe w/ a D16y7 now, 146K on it, compression test told me all the cylinders were at about the same compression, but kinda low, but still boostable. Right now i have a complete turbo kit that i pieced togetehr for my Civic. I was going to boost the Civic, but i was thinking of just selling my Civic, buying this Prelude, then boosting that. I've heard Preludes are bad for F/I because of the high OEM compression (11:1?), so i'm kind of apprehensive to try it, so i've got a few questions....
first off, what do you guys think about $4500? It's got an H23, non-VTEC, 110K on it i beleive, and all new OEM suspension (worthless anyway since i'd lower it ASAP). Think i should talk him odnw to $4k or $3500?
second...what do you guys think of boosting the Prelude? I wanna boost that since it has less miles on it, and also MUCH more torque, and a lot more power right off the start. The turbo kit i have is basically universal, other than the turbo manifold, which i'd have to replace with an H series one (all H series exhaust mani's interchanable? That'll help me in the future). It's a VJ11 turbo out of an old Probe. It's a little smaller than a T25, going to be running at 8 PSI, intenrally gated, and just leaving it at that. So its a small turbo, low PSI, looking for a gain of 75-100 horses, idk. Got some 450cc injecotrs (DSM bluetops), a big ol FMIC, 2.5" charge piping, prolly would stick with the Sknuk2 catback thats already on the Prelude, and then have no idea about the ECU/tuning options, which i could use help with.
sorry i was in a rush with the last post, but i guess with the ECU/tuning, i know whats upw ith the OBD2/OBD1/piggyback/standalone/etc., but just didntk now if Preludes run the same type of ECU's, or if its even possible to convert back to OBD1 with a Prelude/H series. If so, then i can take it from there with tuning, but if its not possible to convert/tune the ECU, i dont really have the money for a standalone, and piggybacks arent worth a crap, and i guess thats what i should have asked.
and i did read the stickies over there....so i guess its pretty much build or no boost? Even on 8 PSI on a small turbo? I'm trying to find the specs on it.....haha and i just dug them up. Turbo specs are:
VF11 Turbo Specs:
Inlet Diameter: 2"
Outlet Diameter: 1.75"
Air Flow Rate: 1.4 - 10.8m3/min or 49.4 - 381.4ft3/min
Max Pressure Ratio: 2.8
Maximum Speed: 18540rpm
Compressor: 0.4 A/R, 37mm trim
Turbine: 0.52 A/R, 40mm trim
It would be my DD, which makes it hard, but if i got a good tune, and some head studs, and kept the boost low, possible at all?
nobody? I was thinking about it....maybe Golden Eagle rods, ARP headstuds, then think i should lower the compression a bit? I was reading up and the H23 has like 9:1 compression, no? Thats about the same as my D series now so running a low level of boost doesnt seem like it'd hurt it TOO much....idk, you guys are the Prelude guys tho, so you tell me
At one time, there was a pretty large database consisting of boosted preludes, what type of FI they were running, amount of boost, when they blew up, and why.
I don't know why stev3 would throw out such a generalized blanket statement.
yeah i read that sticky about whose engines blew and who's werent....so it seemed like there were more people running boost who HADNT blown as opposed to people who had.....what do you think? I see soem people throwing up magic numbers like "300 whp and then you risk internals", but looking at the numbers on the H23, it only has 160 hp and tq right? Well i'm looking for between 200 and 225 probably, definitely not any higher. This is a small turbo that REALLY falls off at higher RPMs. Think its doable?
You can do anything, given enough time and money. Personally, I think that you'd be dumping way too much money for an extra 40-65 hp. If nothing else, you might consider nitrous.
well....now that i think about 250 might be a realistic number. Idk, what is the weak point of H series? Rods? Are they prone to headlift (anymore that any other Honda engine)? Cylinder walls? Not really looking to sleeve it, and i know its alot of money but i ahve the whole kit pieced togetehr already and just cant decide i wanna boost my D16y7 or buy the Lude and just boost that right off the bat.
lol i know man, but my suite-mate wants to sell me his Lude and i got this whole turbo kit pieced togetehr and ready to go, so if i buy the lude i dont wanna just sell the kit, i want the pssssssssssssssh
RINGS and pistons. You should be able to do mid-high 200's on the stock block safely all day WITH PROPER TUNING BY AN EXPERIENCED TUNER AND A STANDALONE (Neptune, Hondata, AEM, etc....)

buy the lude oost it between 6 and 8 psi it should hold together with stock internals giving you around 220-255hp wich sould be what you are looking for right now...then as u get money build it up and run more boost!! i have a h23 that over time was rebuilt piece by piece and im runnin 19psi and 430hp and its so fast I out run all stock v-8's and most built ones!
Also if your running vtec you gotta take that off when you go boost!!

Reason: adding on
naw the one i'm looking at is non-VTEC. I'd so head-studs if i boost it, and it's going to be professionally tuned on Crome w/ an OBD1 ECU from Phearable.net.
