So, I have been thinking about the route I want to go with my car (mods in sig) and have truly pondered a TVS swap. However, there are a couple points holding me back from pulling the trigger on anything yet. For one, the car is my DD. It is reliable on the setup it has now and I'd like it to stay reliable. Secondly, I dont have E85 in my area (just checked tonight) so I'd have to run water/meth for anything aggressive on a TVS or even M62 to be safe. My goal for the car is 300-330whp.

The options I've considered are:
1) TVS swap - possibly pulley down if needed but stock pulley may be sufficient for my goals. However, smaller pulley nay require E or meth.
2) Ported head/cams + 2.7" on M62 - not terribly far off in price from a TVS swap. However, you could throw a 50 shot on the car with this combo and probably be very happy.
3)2.8"+ported head+nitrous - similar cost as option 2 but less daily fun factor without cams.
4) MP-90 swap + ported head - could be an interesting swap but also more experimental.

thoughts? Flame suit engaged!!1!!

 

You wont need e85 to make 330 on a tvs, that should be pretty easy on 93, as for the mp90, everyone talks about it but nobody does it so i dont think its feasible really since you want a reliable DD.

 

Tvs on pump gas and a little bigger pulley will last quite a awhile and be pretty reliable. But that also falls back on the tune too

 

That is what I am leaning towards. However, how low can you legitmately go before you have to start running meth? I have H/E & Dual Pass right now on a 2.9" M62 setup. I know the TVS is much more efficient and thus it demonstrates lower IATs but has anyone hit 330 without meth or E85 (stock head/cams)?

 

if you want a car to be reliable the general idea is not to modify it. it only makes them worse.

 

I think that's understood I had a heads/cams/nitrous mustang as a daily. I know about things breaking. However, given I don't drive my car like a ricer and only occasionally beat on it, that is why I am ok with getting a little more power for fun.

 

I dunno, the TVS is a nice piece but it seems without Meth or E85 the chance to blow something up is too high. For a DD its hard to get into super modding like you want to do, cause as you know the more you mod the more unreliable it becomes. However, with that being said I think a turbo swap would be better for your power gains and be easier on the motor. a 20g at 15 psi would be right around where you want to be, and the motor would thank you for it. compared to 20+ psi with a TVS which is much less efficient than a turbo.

However the linear power of the TVS is what makes it so nice.

 

This is what I am thinking as well. Ported head/ported blower/ZZP stage I cams with a 2.9 or 2.8 would pretty easy to DD as well. The turbo swap sounds great but I don't want to dump $4-$5k into this car. I'll just buy a c5z lol

 

that makes sense.

 

hell if I had the money I'd just buy the C5Z. It's even rear wheel drive.

 

I have this life mod called a 3 year old so that's not in the near future lol

 

Working on a failsafe for meth so it's "safer".

 

So a little update here. For now, given this is my daily, I've decided to pulley down and run meth. However, I have the option of running a 2.7" or 2.8". I also am ordering a phenolic spacer as well for IATs. Down the road if I want a TVS, I will already have meth set up for it.

The question is, 2.7" or 2.8"?

 

Edit: Just buying a TVS lol

 

I live in ft myers and run e85 and drive daily to bonita springs

 

Also goodluck on whatever you purchase

You dont seem the brightest when coming to anything modded and your ss sounds like complete horseshit

 

without meth or e the chances of blowing something is a bs statement people have put a 1320 and ran them for well past 50k with no problems and a turbo is a lot harder on the engine and the driveline then a blower will ever be the reliability comes from the tune

don't waste your money on a phenolic spacer they don't do as advertised

 

I have an tvs on my cavalier with just e85, option b.
Not even a dual pass

Has built engine though

The spacer is in fast lame

 

post some pics of the cavy

 

Will do

 

 

With m62 few years ago
(Photoshopped white) , still silver will be white within few months

 

Lol not sure when you heard my car. It did sound like horseshit with the old exhaust on it. It has a shorty ZZP header, catted 3 in DP and 2.5in catback on it now. I come from the world of big dumb v8s. I swapped heads/cams on my old car and did the nitrous kit. Everything on the car except for the gear I did and ran pretty well. I am not mechanically retarded lol I am, however, the first to admit when I don't know something about a platform that's why I signed up here to ask questions and learn

 

I know you blow the supercharger **** all the time, but dont tell me that a supercharger is more efficient than a turbo lol.

 

hey *** dumpster did I say it was more efficient then a snail. a turbo is harder on the drive train and engine from the how the torque and horse power come on
