95 Corvette build

[Demoncorvette]

Hello everyone,

I just got my corvette recently, back in September. I really love it so far. I'm looking to plan a build for the future. I will be gathering parts over time so cost isn't so much of a big deal for me, within reason of course.

The only plans so far:
383 or 396 stroker, with forged internals and an overbore of .030
Long tube headers (Thinking Exotic muscle full length 1 3/4 with cats)
BBK 58mm TB
Probably ported lt1 intake manifold
1.6 Rockers

I don't know about the cam so far. I'm thinking about something with at least a .500" lift. The actual heads...I'm not quite sure what I want to for that. I'm thinking darts or afr. Though after that, I'm not too sure. The car came with some aftermarket exhaust, though I haven't been able to figure out if it was a system or just custom exhaust. It has magnaflow mufflers and resonator. But everything before the resonator looks stock. It's an automatic transmission. But I'm planning on getting a manual valve body with a shifter. I want to build it to hold the power that I would like. I want to give it close ratio gears. I have seen some from Sonnax, I believe. I have been looking at the efi connection 24x or 58x ignition. Has anyone dealt with that or heard about it? The power I would like it to make is about 500-550 whp. Is that too much power to hope for? I'm don't mind using power adders. But I don't really care for nitrous.

Nice plans for a great build. I would recommend AFR heads and take a look at Torque head 24x conversation. I read about problems with the EFI conversation. Subscribed.

Torqhead doesn't work for corvettes.
You'll have to do EFI kit.. I haven't had a single problem with mine..

Really? Why? What is different in the vette?

Digital Gauges won't work AFAIK.

[Dan]

Unless you're wanting to run a 6l80e, 24x is all you'll need.
24x uses 0411 pcm, 58x uses whatever the Ls2 and up use.

[Demoncorvette]

I didn't know about torqhead. I was looking into efi connection. Which would be better the 24x or 58x? I know that the 24x would be similar ignition as the ls1. But the 58x is the newer ls. If I read that correctly.

Idk why that would make a difference... but much of the vette dash is still needle with the electronic display in the middle with other info as well as duplicate info depending on the setting.

It just says they offer no plug and play system... it doesnt say it won't work though. The motor takes all the same connections as an fbody I believe...

It'll work, but just have to make compromises. CCM issues is what google told me.

58x ain't gonna be worth the headache

[Demoncorvette]

That was from efi connection though? Does that only apply to the 58x? Or the 24x as well?

[Demoncorvette]

Anyone have any knowledge of exotic muscle headers? It's almost the only company that makes long tube headers for a corvette.

[Demoncorvette]

Finally got around to getting parts for the Vette after moving. I have an mad cap and rotor and mad blaster coil. I'm looking into a better mechanical water pump.

Hah, no such thing as a better mechanical water pump

Are electric water pumps reliable? Have you heard of any problems? I'm just trying to get information. This is the first car that I can actually do something with and I don't want anything to go wrong.

[popo8]

Ive only run ewp in all my lt1 cars...

I always run ewp. Summit brand or meizure, never csr. Had two csr bad out of box. One meizure I have as a spare has over 100k on it, I removed it because I got a free summit pump and the meizure was rusty looking, lol

I like the EWP for simplicity but it's more for drag/street cars that don't get pushed for extended periods of time. I've never had problems with the Mezieres. My old Jegs pump shit itself after about 3 years (sounded like a garbage disposal) and I think the Summit pump (CVR) on my Buick is dying because it keeps blowing the fuse at startup.

I drove my 602rwhp boosted camaro for about 50k and several motora with my summit ewp on it... was still going the day I crashed it... many long road trips including 1400mile round trip to KY...

All my previous cars were daily drivers.

Well yeah I think the EWP is perfect for a DD. Don't have to worry about the pump leaking all over the opti and changing it is easy as hell. The Camaro was my daily for years with EWPs and the Meziere that's been on it has yet to give me issue. Current Summit pump on the Buick has been iffy despite rewiring it twice and playing with different slow blow fuses. I'm probably going to throw a used Meziere on and keep it as a spare.

The EWP flows less than a mechanical pump beyond ~3k rpm if I remember correctly. Fine for drag/street car stuff but I wouldn't want to go road racing or do a standing mile with one and a stock radiator. If someone could figure out how to plumb a remote pump in parallel then it probably would suffice.

In the spring we are gonna try to hit a standing mile or half mile with osies car, stock rad, ewp, 160 stat, ac and big front mount LOL

I'm thinking about just keeping my water pump for now. I should focus on suspension. I'm probably going with Bilstein b6 HD shocks.

[popo8]

Are u planning on driving it on the street alot? My c4 had a very capable suspension from the factory... idk if it wouldve lost something as far as enjoyability on the street if I made it any stiffer than. Factory. Then again... mine was really a 85 which was much rougher than the later vettes... http://uploads.tapatalk-cdn.com/20170102/a741d7ad075e48de771565505786dfa8.jpg

Mine just kind of floats. I want a tighter suspension. The b8s aren't that much more than the b6s anyway. But once it's build I have a 71 cj5 to drive everyday.

Hello everyone!

This last weekend I spent Saturday installing my MSD cap and rotor and MSD coil. It was somewhat of a pain. But overall it wasn't bad. I do have pictures of the progress.

I ended up replacing some vacuum lines as well. The opitspark was really bad. I'm surprised it ran like it did. It did run rich. But now it's a lot better. Next stop is steering!

Keep an eye on the msd coil. They've been hit or miss now a days since msd got sold a few years ago.

Thanks for the heads up! At least that is easier to get to than the opti. the old opti was leaking oil. Everything was pretty bad on it.

I'm trying to think about my first actual performance part. Any suggestions?

start small, intake, 160 stat, electric water pump, catback, tune, headers, cam, heads, 383, nitrous or supercharger..........yeah yeah, thats starting small

[popo8]

Lol... if money is not an issue... id suggest a top end... new heads cam intake for it.

Soon money will not be an issue! I'm still trying to decide on building a high compression or supercharged engine. It won't be daily driven at that point with either build.

Supercharging a y- body can be a pain when trying to make power due to the belt size and routing restrictions. If you're serious about doing it, look up www.blowerworks.net. he's the y body supercharger guru

I have seen that before. Definitely where I would go for a supercharger. For a tune though, I know a dyno tune is best. But I don't think there is one here. Is there a good mail order tune?

[popo8]

Well hell if its not an issue... build a full motor... forged internals and boost it.

I have had moe tune me n/a stuff email tune. You have to have the proper programs and a wide band plus time either on a dyno or able to do good street pulls for a good email tune. Good logs make good tunes when the right person has them. Whatever you do, stay far away from anyone named solomon

I have been gone to get a job. I'm going to be able to start buying parts slowly. I'm going to start with full exhaust. and probably 58mm TB. Now, for tuning that, how would I get into contact with Moe? I think I can get time on a dyno for the data logs. So that shouldn't be an issue.

don't put the 58mm throttle body on until your motor is built. no real benefit to a stockish motor except tuning headaches and risk of vacuum leaks upon other issues. I tagged Moe in this thread for you

Hello there! Just so I'm clear, Popo8, you are Moe correct?

Also, I don't know if anyone has heard, but there is a group out there that has a lead on an aftermarket lt1 block. I think there is a facebook page, ltx motown.

no, moehorsepower is Moe bailey, the tuner. popo8 is Lawrence, the owner of this here forum.

yes, ray and the boys are the main part of that campaign. they are members here, and we have threads for that as well going over all the details.

Awesome! I have been looking for a tuner!

Would an lt1 with a supercharger be able to run on e85? Currently it is in Cali (Not registered there though) so e85 is very available. I know I would have to change the fuel system.

We have a couple boosted cars on e85 here.

[Demoncorvette]

I will probably look at e85 when I get to the boosting part of the build.
Does anyone know if Corsa or Borla has a 3" exhaust system? I couldn't find any.

[Demoncorvette]

I haven't really done anything to the car in a while. I'm trying to get around Cali's emissions for Long Tube headers. I'm probably going to stick with the magnaflow catback that it has on it.

Also, I'm second guessing myself on supercharging. If build properly, how much would an N/A engine push? I couldn't really find any examples.

[SSlowBoat]

ellweinengines.com has built plenty of n/a engines that make great power. the whole cali thing is what's gonna screw you with making power.

I'm going to be moving to Texas in maybe a year. Then, I won't have to worry about CA's stupid laws. I think I can get away with long tubes for now in CA though. There are somethings that I could do in the meantime before I move.

[Demoncorvette]

i might be able to get away with long tubes. As long as they still have the emissions on them. I don't think a lot of the shops realize what kind of exhaust it should have.

Also, I have started to figure out what heads I should get. The AFR 227cc LT4 heads with compcams grind 276HR-12. With the LT4 intake manifold, probably some porting

that's not gonna pass any emissions

[Demoncorvette]

I think as long as I have quality emission parts (cats, egr, etc.) It would pass. I know LTs are not allowed in CA. But I know my dad knows people that would look for only what is required and as long as it passes the sniff test.

I have also found LTs with emissions on them.

I could also swap out for emissions or wait until I move.

[Demoncorvette]

I have decided that since I will be in Afghanistan for the next 12 months. I'm not going to worry about trying to upgrade right now. When I get back. I'm moving to Texas, then I will be doing things to it.

[Demoncorvette]

I'm really wondering about the Torqhead ls1 conversion. I don't know if I would want to spend $2000 on this. But on the other hand I would have an easier time trying to tune it. The price tag is what I'm having a hard time with. I read that Torqhead does work with the C4 dash. They just repin the ls1 PCM. Has anyone else done this conversion? Is it really worth it?
