MPH 118.34

Now, this was the 1st pass and best of the day. The car was breaking up at the top of 3rd and in 4th gear and so he backed out of the run. Later runs only got worse. As it turns out, the fuel rail bolts had backed out causing the #1 injector to intermitently pop loose and spew fuel. We also think there may be some type of ingition problem as the breaking up only happens above 20psi of boost. You can see the car almost went 98mph in the 1/8th. The launch was crap because the new tires were not warmed up enough. Anyway, 11 seconds on a $400 long block.

hot damn!

Congrats man!

Good times..good run. Nice work!! :thumbup:

Can he go any faster on that block? Like 10's? Or is he maxxed out?

that's swt man! lucky bastard :)

you deserve that after all the work

good job that is really fast I can't wait to see everything totally fixed you think it can get into the 10s!??

nice work. Honestly did not think anything special would come out of that engine in an FD

Nice work! That seems like a pretty successful conversion to me. :)

-Max

wow

impressive!

forgive my ignorance, but what is a SR20DET? Is that a 240 engine or something?

nice work!
should see low 11s hopefully with the car fully sorted.

And what a 240 it is! Stroke that bad boy to a 2.5L and you got yourself a party!

I am trying to get it all sorted out and take it to Gainesville this week, the block will stay stock but in addition to fixing the few bugs i am going try to get some cams before i go we will see... still trying to reach my goal of 10.99 on a stock block.... Also any of you guys that run et streets what tire psi are you running and any hints on rear suspension setups would be greatly appreciated.... Oh also I was thrilled because the weight of the car is 2635 with about 8 gallons of gas

Shaun

I'd try about 20 psi and drop it down a little if needed

it is a Jap spec "Silvia" motor... which is the 240 in japan, also is turbocharged stock...
-Keith

The motor is a 2 liter motor it is not the 2.4 that we have here in the US.

Man do I gotta whip out the Jun Sports Silvia article? It was an S15 where the injectors were bored (stroked) to handle more flow. Hence at the end of it all, it was pushing 2.5L instead of 2.0L. Of course, the damn stroke kits cost damn near $10K, but who am I to complain :).

tnt are you comming to race at the gainesville raceway? Let me know when your going to be out there I want to see this beast.

-Todd

isn't boring enlarging the cylinder bore and stroking installing a longer crankshaft? (nothing to do with injectors)

wow...
 

nice! ;)

It doesn't mean that it still can't be stroked and bored....

Yes you can bore injectors. 1300cc secondaries for the FD are typically bored 850s. Can't stroke an injector though :)

I am trying to make it, we are really backed up here at the shop, but i will know for sure on wednesday

Shaun

I think that was the point, injector size has nothing to do with displacement. :)

How come everything in Japan is turbo, and we get all of this N/A crap. Yeah it's more reliable, but I'll take power over reliability anyday.

damn dude.. very impressive :bigthumb:

Its because the Japanese are smarter on average than Americans. Why do you think we're driving their cars instead of them driving ours'? Look at all the drivers over there who are drifting experts. Turbos are reliable if maintained properly, but then there's those dumbasses who beat the crap out of their cars here. Could have a little bit to do with the fact that they don't have Pep Boys over there... they've got HKS, GReddy/TRUST, A'PEXi, RE-Amemiya, Signal, C-West, Veilside, Blitz, e...t....c......

I don't mean to offend anyone, but Asians just know how to take car of business. The old values of nobility are still in existence there and there is a large emphasis on success and performance. Its too bad, but hopefully our country will begin to grow back in that direction with the new flow of automotive engineering into the US. If only the Evo VIII would come with the viscous coupling differential and active yaw management. To them, its part of the car, but here, they rip it out and charge you an arm and a leg to have it installed. All about the money.

Mako, I would have to agree with you on alot of your points, especially about the japanese still maintaining an excellent value system when it comes to thier job... There business is family and one of the most shameful things that can happen to you is to get fired.... They really take pride in what they do which is why they are so successfull, however the reason they turbocharge and build smaller motors than the U.S., i think is because they have more of a sense of a complete car... Here they would throw a big V8 in it lighten the car by getting rid of creature comforts and not care about gas mileage, you may end up with a fast car but it is nowhere near complete... Not to mention the fact that it is hard to tell a GM or Ford to ditch the very thing that has made them billions of dollars.. On the bright side I think the domestic car manufacturers are getting better due in no small part to the influx of the younger engineers... Just my 2 cents

Shaun

Much of use of small engine sizes in Japan (and the far east in general. ex. in the early '90s, it was not allowed to import a Japanese vehicle over 3 liters to Taiwan) is more likely due to regulatory reasons (taxes on larger engines, etc). With goverment regulation making smaller capacity engines more widespread, manufacturers had to be creative to squeeze more hp out. This forced the Japanese manufacturers onto the bleeding edge of tech if you will.

Also, keep in mind that Japanese products were not associated with quality until after Dr. Deming and his concept of Total Quality Mangament influenced/revolutionized the Japanese manufacturing industry in the '50s. Since then, of course, Japan Motors Inc has been kicking the world's ass.

Despite stereotypes, human nature is human nature - we (humans in general) are inclined to do less if we do not need to (witness the US auto industry up until Japan Motors Inc nearly killed them off). So, it's likely that economics that forced the use of smaller engines in Japan and the need to make them reliable (and maintain that edge) at higher performance levels. As always, money makes the world go 'round.;)

sure sure what ever i want to put a f-16 motor in my rx7 and see what happens. hahahahaha


hey shaun hold off on all that shit for the rx7 i think i have it sold and if so i am getting my type-r back. guess what i am buying it for 5k less than i sold it for, plus it has the cp0-35s hahahaha rocks huh.

ill let you know what im gonna need for this car, you can bet it will be getting a new hood and some other shit. hopefuuly i can get the rx7 sold very quickly. send me an email you bitch!!!

good times on the srx. to bad it didnt make the 10s but damn its still not bad. when you gonna ship it to the new owners house??


later scotty

The reason we`re driving their cars and they`re not driving ours is because Japan has insane import restrictions imposed to strengthen basically all of its domestic manufacturers. The classic example of this was when the Japanese government tried to help its ski manufacturers by banning all imports of French skis (the leading producer at the time), claiming that they were unsafe because Japanese snow is different from French snow.:confused: Anyways, the protectionist policies are all part of what was a very successful cohesive economic policy that allowed Japan (and much of the rest of Asia under their lead) to achieve incredible growth until the bubble burst at the end of the 80s. As for Asians having stronger work ethic, that may be true in many cases, however I can personally say that the consruction workers I see every night lounging around the job sight on Shinjuku-dori here in central Tokyo on my way to the conbini over the last 6 months surely do not exhibit the stereotypical strong Asian work ethic, nor do many of the other individuals I see around the city. This isn`t to criticize Asians, or say that they are any better or any worse that anyone else, I`m just saying that some of the above statements are clearly stereotypes and nothing more. Sorry to clog up the thread, but I thought I would just voice my personal experiences as an outsider living in an Asian country.
