not everybody could do 300whp on a 14b.I just logged a friends car. He has a 14b turbo boosting at 17psi, 450cc injectors. 1G engine, FWD lancer. It pulls good.86% duty cycle. 609 maf, 255 lph, afpr set at 45psi. rechip. Tuned at 11.0:1 AF ratio, 22* peak timing. barely knocks. 95...

Hi,We got an Evo 3 GSR tranny, tcase and Evo 3 rear diff w/ LSD. We're planning to install it on an 1G eclipse.Whats the best / easiest way to do it?1) Retain rear diff housing. Replace ring and pinion gear? how bout the LSD? 2) Can we use the whole rear diff and will it bolt on an...

mmcd 1.8. weird. I trust the logger than anything else. Im thinking the low voltage is the reason why Im leaning out at 5.5k rpms up.Ive seen 13.7v at idle and 13.2 at WOT on my friends car.

Hey guys, do you have the same reading from battery voltage and logger batt voltage?Mine reads 13.1 from data logger during idle. Ive let a battery shop test the battery. It reads 14v (healthy reading)During WOT/hi load, logger batt voltage drops to 12.0vI've checked my AF using a...

Ok thanks for clearing that. Royal purple is expensive and overpriced here in the Philippines.How about a synthetic motor oil like 5w30 10w30 in the mix of the Redline MT90?

Hey, thanks for clearing that. Ive read a similar thread here, and its BG + Redline shock proof. Even Shep agrees it is compatible.I did use pure ATF(cheap brand) before, shifting was so smooth. No problem for quarter mile runs. But I burned a bearing at long hi speed driving. 180kph. Do...

Can I mix these two? 2 qts MT90 and rest is BG. I have a half qt bg and I dont want to waste it. Ive read some articles that you can mix synth and non synth oil. We dont have MTL here in the Philippines.

Ok, heres my feedback. We've used it pure on up hill races, drag.We're using an Evo 1 engine, 8.5:1 stock pistons, stock hi load timing is at 23*, stock AF is at 9.22Using pump gas, Im already knocking at 15psi boost, 12-15 counts of knock. timing reduced to 15*.On pure avgas, (AF:modified...

haha! I'll just commute to work and use the car on weekends. I'll wait and see who does this thing first and make it perfect.

Ive done a few searching and I've found out that some of the Mitsu cars came with LPG kits from the factory. In fact Mitsu Motors backed up the kit / car with a warranty.Lancer Cedia, Mitsu Shogun, Outlander etc.Mitsubishi Motors UK, Austrailia does this.I know they have kits for...

thanks for the quick reply.Im from the Philippines. Its always warm here. Do I still need to warm it up? Ive seen a lot of taxis here run on LPG. Ive heard a story that it destroys the cyl head or something. Lets say I'll be able to tune it to the exact LPG AF ratio, will it perform the...

bringing this thread back.. any ideas if LPG can do good on our 4g63s?Petrol prices are getting higher and higher.

TD04HL came from a mitsu RVR. Its like a Honda CRV or Toyota Rav 4. The engine is almost an Evo1 - Evo 2 engine. ECU has an eprom that is programmed for 450cc injectors. Motsly are ATs AWD.

ok. Ive changed my rear tires to the same tire size in front. 195x60x15. The rear are of different brand but almost have the same treadwear, same rating, same tread pattern. It should be better and it feels better already.

I guess not that many.If my thinking is correct, the VC will just take care of the torque split. less tire spins for the bigger diamter tire. It will jerk if its a normal 4wd. I dont feel it. Now why would the VC get damaged? Isnt it like changing the ratio in the rear diff? What Im...

Ok, I did some searching. Some certified mechanics says is its ok.Isnt the center VC allow the front wheels to turn at different rates from the rear wheels. This is generally necessary for normal street use.Heres a quote from some ASE mechanic "Ask yourself this: How exactly is having...

I have 195 x 60 x 15 up front and 195 x 65 x 15 at the back in my Galant VR-4. Is this bad? Please explain why would the VC suffer? The front tire speed is independent from the rear because of the center diff. When youre turning or even on a straight uneven road, tire speed up front are always...

Use the Cyclone manifold. Its the best OEM manifold. It compliments the large ports of the 1G head. Only the 4 long runners will work under 4k rpm. So it should feel as efficient or responsive as the 2G. After 4k rpm, the other 4 short runners will open and you'll feel the difference in torque.

Evo engines are all 7 bolt and dont use cyclone manifolds.If its a cyclone, its from a JDM Galant VR4. The ordinary VR4, comes with 14b, 450s and Cyclone turbo intercooler. Some of the JDM GVR4 have eprom ECU. The RS / Montecarlo/ Super GVR4 version comes with 16G, 510s, reflashable ECU...

Ive found the problem. Its the FPR. I removed the return hose from the FPR, start the engine. Theres no fuel coming out from the fpr. I replaced it with a surplus unit. Now it reads 37-39psi at idle, vacuum off. 30-31psi, vacuum on. I took it out for a test drive. Turn up the boost...

I'll try to check on the reading after the car is shut off. I remember its around 20psi. If vacuum is disconnected, it will be higher by around 10psi. The reason I installed this gauge is because Im having problems boosting past 10psi. at 10psi, it runs great and revs smoothly to redline. 2.5...

Thanks for the reply Steve.Now I understand. So is it ok that I cut the fuel hose into 2 and inserted the brass T fitting with gauge between the fuel rail and fuel filter? Will this cause some discrepancy in reading than the one mounted at the rail or at the reg? Im 20psi off the normal...

Hi,Ive installed a T fitting with pressure gauge(0 to 100psi) between the fuel rail and fuel filter. I'm getting high readings at idle. Its around 47-50psi with vacuum on and close to 60psi with vacuum off.Car is all stock, stock fuel reg. GVR4. I doubt it if the fuel reg was changed...

after reviewing the hoses, I guess I can remove the FPS in the left most Intake vacuum nipple and run a straight hose back to the FPR. I'll probably try to cap off the 2nd intake nipple for the cyclone and see If I can eliminate vacuumleaks. I guess capping off the 2nd/middle nipple will...

Hi there!Id like to remove the emission hoses in my JDM Cyclone GVR4. Anybody there that has a diagram on how to do this? Ive only found a diagram for a 1G DSM. Heres the JDM diagramHow can I do this without messing up the cyclone activation? Is it possible to just let the other 4...

Hi there!Id like to remove the emission hoses in my JDM Cyclone GVR4. Anybody there that has a diagram how to do this? Ive only found a diagram for a 1G DSM. Heres the JDM diagramHow can I do this without messing up the cyclone activation? Is it possible to just let the other 4...

Thats too high. It should be around 36-37psi on a 1G. I bought the 190 because I dont want to buy an AFPR. Just to be sure, I guess I need to remove the relay and use the stock wiring.At another website, yes, the gauge should be before the FPR. I'll insert a T with a gauge before the rail...

ok, I'll give it a try. Where did you put the gauge? After the fuel reg or before?

Does it maintains 1:1 pressure to boost? Thats the important thing.You dont have an Adj fuel reg? Just a gauge? Do you mean, by just installing the walbro 190lph plus relay mod, it reads 40psi base on the stock reg?

Can the 1G/GVR4 stock fuel reg work with a Walbro 190LPH plus rewire mod?Im using a stock pump that is rewired. I'll be replacing it with a walbro 190. Should I remove the relay/rewire mod to accommodate the stock fuel reg?

Im using the stock JDM ECU that came with the JDM gVR4 cylone engine. Im not sure if the vac lines are correct. Yes, from what I know, it should activate around 4k. what will I look for?.. to see if activates. Should It open even revving it at neutral?

How would you know if your cyclone intake manifold is not working properly? Im having doubts that the secondaries in the cyclone intake dont open. Im having a little of hesitation around 4k rpm under boost(14psi 14b). No misfire and it doesnt feel like its running out of fuel.-- 88 Galant...

many thanks for all your answers.

--Boost controller boost source--ok. Theres a nipple on an intercooler pipe before the BOV. Im using it right now, is it ok? I dont have a nipple on the J IC pipe after the compressor housing.

Thanks for the quick reply absolute_DSM.Sorry, I didnt make it clear. I was talking about the boost source for the boost controller.So, is it ok to just run a vac hose coming off an intercooler pipe before the BOV and after the intercooler? The nipple from the IC pipe is between the BOV...

Hi Guys,Whats the difference if you use the boost source in the intake manifold-BOV vac line and using a pressure line on a nipple coming off an intercooler pipe after the BOV?Ive always see DSM guys use the intake manifold-bov vac line. Whats the reason? Why not just use a nipple of an...

Yes, Ive heard good things aboout E85. I can live with those E85 issues. Problem is, E85 is not available in the Philippines and second, my injectors are too small for that kind of AF ratio.Ok, I'll give avgas a try and update you guys.

Thanks!So I just use pure 100LL, lean it by -10 in SAFC?Im using a 1G engine, E3 16G turbo and Evo 560cc, 2g maf,rechipped and all the supporting mods.At the moment, Im running 20psi with water injection. It runs ok. I'm planning to use it for one race and up the boost to 25psi. Would...

ok, what a/f ratio do you use on 100LL?Do you run it like pump gas?

What will happen if you use the E931 USDM code with the Cyclone manifold? secondary Butterflies wont open?

We're running 1000cc at 37psi base pressure. 28psi max boost, no problems.

So whats the best timing for a 1G using E3 16G at 18psi of boost?I'm seeing 15,16 and a peak of 17 degrees on my car at 17-18psi. Its knocking hard at hi rpms. I'm thinking to recurve the timing map in the EPROM. I'll try to make the last map to peak 16 degrees. Do you think this kind of...

brisvr4, thanks for posting the part numbers and clearing it up. You could've said it much nicer though.:)Yes, I know the rs maps are more aggressive. I'm using the program of the 5808. I used to program and edit those maps into a less aggressive timing curve for our low octane fuel...

You might have the VR4 RS variant. The VR4 RS comes with a 16G turbo and 510cc injectors and rated as 240hp stock.They have different cams, probably same as the evo 3. Springs are stiffer than the 205hp JDM vr-4. The idle speed from the ECU code is set at 872rpm vs 768rpm on USDM and...

Sorry for bringing this thread back.I was wondering If I can regrind my stock JDM VR-4 cams to HKS 272/272 specs.There's a reputable machine shop near our place and used to do cam regrinds.What do you guys think?

Yes, thats true. I've already seen the data. The source is very reliable. The good thing is its range, its good for 60+lbs/min. You wont overrun it until 600+HP.

Thats another thing I'm worried. I'm not sure where Philippine 96 RON gas falls.Some of my friends say Philippine 96 RON is no better than US 91-93.Can I add 10% Methanol?

Andy,On what RPM should I not go below 14 degrees? I plan not to go lower 20 lbs of boost and not to use fuel lower than 96 RON. I plan to use the Galant RS JDM fuel maps, they are a lot leaner than the USDM map. Around 10.1 at the highest load vs 9.3 of the USDM.I will use the evo 3...

Andy, daren_p, shortydtp thanks for the reply.After gathering your input, I guess I have to run above 16 degrees of timing on 20psi ."I would shoot for around 22-24 psi on an 11:1 with 16 degrees of timing." -- I'll try this.

E3 16G guys/16G guys, whats your timing advance on pump gas?steve, andy.. please comment.I'm undecided on what fuel and timing maps to use. I can extend the timing maps more than the stock USDM maps. USDM Maps are maxed at 29-31 lbs/min. I can take away timing to run 20-25psi on pump...
