Seeking tech info on tubroing a prelude. I have a friend thats tubroing his prelude this week. Also he is installing a vtec controller. How will vtech affect boosting, and whats a safe Psi without a controller and safe Psi with one. Oh sorry its a 2000 vtec. I know toyota's vvti gets in the way when adding a turbo to a N/A supra, these should be the same with vtec huh? And whats a good rmp to set vtec to with boost. He also installing bigger injectors at the same time. Hes getting the boost and vtec dyno tuned when it gets installed but i wanted to talk to some honda techs first. Would get him to lost this but he would get lost reading the replys and i don't would him to become a ricer with a turbo. P.S. He was 2 13" subs with a bat in the back and 3 amps (200lb) how will this affect the cars speed.

and you're not providing nearly enough information about the setup

 

known someone was going to say that, ****. Hold on I get more info.

 

This in the turbo is a t3 with a small *** intercooler( about 2 x 2) getting custom down pipe built and manifold, slowly getting the info from him. he just got back to new orleans after leaving from the storm.

 

It hurts reading your posts.

 

450 cc injectors

 

he's running a 2 x 2 intercooler? wtf? That's smaller than an index card.

 

r u running a radiator for i/c??? t3 is pretty small for a h22 also

 

2 ft x 1 ft - damn you honda poeple harsh

HAHA

 

So you don't have much information but i can give some advice. Vtec and boost a subject that is very opinionated. Some like Vtec and boost and others don't. I guess its all on the owner. All in all VTEC should not affect boost. Anyways about how much PSI your friend should run. The Vtec Controller plays no part in determining this. It matters on if the bottom end is built for boost or not. If your friends motor is not built then to be safe i would not go over 7psi on a stock block, due to the high compression and stock rods. Now lets say your friends motor is built for boost with a compression ratio any where from 8:5:2 to 9:0 with some Aftermarket rods then it would be safe to boost anywhere from 7-15 psi. Anything after 15psi then you'll need a stand alone fuel management system. Although you can boost higher if you choose to but i do not reccomend this since you will have to do some major tuning to get some real numbers put down to the wheels. And the Vtec controller can only do so much. If your friend was smart he should've built the Motor first, but if not then tell him not to boost to much or he will be spending money on a new motor. And i hope he bought a better fuel pump because bigger injectors with a stock pump is like having soup with fork. And for the subs well as anyone knows the heavier the car the slower. And then again its all on what your friend is going for? But if he's going to push over 15psi then i say it really does'nt matter, just don't be taken it to the drags with 500lbs of ice. So i hope this is some what helpful. And if you can please stop spelling VTEC with an H at the end &lt;VTECH&gt; unless your friend is boosting a telephone And i don't think Supras have VVTI???? I don't know Toyota i know Honda!

 

hahahaha that muffucker pulled the turbo kit off a ford probe hahahah

 

Ok heres everthing- 2000 h22 motor (stock), T3 turbo from the rx7 (owner doesn't know the years rx7) intercooler small (don't know the specs very very small, half the size of the wrx's) v-afc2 e-manage and v-tec controller, 450cc injectors (whats a good fuel pump to go with them?)

The h22's compression is kinda high at 10:1CR .. thicker headgasket huh? inline pro or cometic any good? And is there an easy way to get the h22's compression lower for about 8-15 psi? With 10:1 a safe psi 6-8? Lastly should he even installe a boost controller to run higher psi only when needed or should he just wait to get his compression lower?

OH SORRY i put spelled v-tec , vtech ONE TIME
but thanx alot for all the help

particially right

things that are weak on prelude are ringlands, they are always the first to go. No matter how much boost you run you will always want a good fuel management system you can lean out and burn up your motor in a second on 5psi. air/fuel and ignition timing are critical in the performance of your motor. Also you can run as high as 10.1 compression and still run 14psi with no issues. Freind of mine is doing it right now on 92 octane. you just have to retard the timing a bit more.

 

Hey its me again. Yes you should get a boost controller. Very recommended and if you are get a good one ok not one of those manual boost controllers. And for a Fuel pump, most people use a Walbro's 255 lph High Pressure Fuel Pump its an easy install You can get a thicker gasket to lower your compression but you will only lower so much. Mr. Gasket makes some good quality Thick Copper gaskets....but look around do your homework, I forgot how thick you can go. But anyways i recommend you change out the pistons and rods and if you do, do that then you might as well throw a block guard while the motor is apart. I don't recommend you boost up to 14 psi like that guys friends is. There are like 100 reasons why not to boost 14psi on the stock block or engine for that fact. But you if you want My friend did it also. But his piston rings gave out while tuning it on the dyno He was luckier than others. Just think about it 10:1compression with 14PSI whats wrong here???????? Oh maybe its because you just became a suicide bomber . Ok maybe im over reacting but if your willing to start all over cause your motor went to crap after 5months then go head. Send me pics of the rod going through your hood. Boost is nice but boost it to your means save some headache and keep it safe. don't worry to much about a fuel management system right now the E-manage is good enough for now.....and why r u installing a VFAC when you have the E-manage????? So you can look at the pretty somewhat blueish display??? If your looking to press buttons in your car then why not hook up a PS2 lol im just mess'n. Oh and a T3 is hella small guy.....well at least there won't be any lag. And its ok if your grammar isn't that great either. Just mess'n but i did find the grammar book pretty funny. Oh LAST THING your going to WANT A BIGGER INTERCOOLER TO BOOST HIGHER.....OR TO WHAT YOU WANNA BOOST

 

thanx alot good info.... well the turbo is going on this week... will keep post on how it holds up.

 

ok the turbo was installed and the v-afc2 (e-managing and v-tech controller). when it starts boost - it starts to boost then lags off and check eng. light coming on. shouldn't the v-afc2 be able to bypass this. please keep in mind my friend called me to ask if i known anything about it. so i'm getting second hand info. it there something on the v-afc2 that needs to be set to tell it the car has boost.

what are some good injectors for a h22 with boost - if you could give me brands. the ones he order didn't fit.

 

v-tech is god :roll eyes:

 

you misspelled houston.. :/

 

answer to your prayers lol
