95 RS Hahn racecraft Turbo

[nicholas9walter]

I own a 95 RS and i have a ton of money into making it pretty but i need some go to back it up now. I have roughly 5 grand to spend and the best way to go seems to be a Hahn turbo and possibly upgrades. I've been trying to learn about it since i'm close to retarded when it comes to this subject, but it confuses me reading different posts on different cars. I'd like to know what i should do to get some more power, what it's going to take to install one of these kits, and if there are any installation surprises that i'm going to have to spend money on. Thanks a lot to anyone who can help me out, i'd really apprecaite it.

there is a sticky at the top of the page that says "turboing rs/gs" It was written by probably the most knowledgable person on her for this subject. read up on that, plus research hrc and maybe star who make the kits. I know for a fact that hahnracecraft.com has all the info you will need, that added to the sticky written by eclipseRST should be enough to get you on your way. after that.. if you still have questions post away or PM him.. he should be able to help you. Good luck

i read what he had to say, but it didn;t help much with a bolt on turbo, however, he did provide some good information, i had no idea about the head bolts just like i have no idea about hardly any of this. i'm trying though!

If you're more of a hands on learner than thats exactly what you're going to have to do.. just go in and get your hands dirty. Just be careful.. maybe try finding someone in your area who knows a little more about engines than you to help. Maybe go online and look up some blueprints of the 420A and get a feel for where everything is and what it's called. that way you aren't tearing off the wrong parts. make sure you do all the research you can before taking on a project like this... cause one mistake can cost you thousands.. not to mention your engine or car or even life. Good luck

[nicholas9walter]

lol life. thanks man i think that's a good idea about the blueprints. do you know of any fuel type i heard 92 octane. where the hell do i get that shit? and is there any ingectors or anyhting like that i need but doesn;t come with the kit?

[Import2nr99]

You will want to upgrade your injectors, and also your fuel pump. I believe the hrc kit has the pump, so you should be ok for that. I'd say 550 injectors, and also invest in a regulator and an afc. You're only going to be able to boost around 10 psi tops on stock internals. Don't overdo it, or you'll hurt the engine. I'm pretty sure that the higher stage kits from hrc come with intercoolers and piping and all of the other parts you will need. Don't forget to invest in a boost guage and a boost controler. manual or electronic.. it's up to you and your budget. 92 octane can be purchased at most gas stations.. it's just premium gas. and highly recommended with turbo cars. Good luck with the project and holler at us if you need any more info. I'm sure someone other than me will be much more knowledgable. But I'll still try my best

[nicholas9walter]

My budget is roughly 5 g's. whats a regulator and afc? and with the higher upgrades will i be able to run higher than 10 psi. also i heard running boost and installing these kits cause non-stop problems, ture or false?

[Import2nr99]

it all depends on what condition your engine is to start and how well you maintain it. 5 g's is a great budget for this project. especially if you plan on doing the work yourself. a regulator is a fuel pressure regulator, basically regulating the amount of fuel comming from your pump. same with the afc (air fuel controller) it maintains your mixture and keeps you from running too rich or too lean. apex makes a very good one (apex s-afcII is good). If you upgrade your internals... with say eagle rods and weiseco or je pistons you will be able to boost greater. But it requires fine tuning of the fuel system and careful monitoring of your engine. eclipseRST is running a 20g on his rs and is at around 350 hp I believe.. don't quote me but it's up there! he has about 4 grand or so into the car, so yes.. with the knowledge and money you will be able to build a respectable car out of your NT. Everyone will always bash turboing a non turbo car... because it's just not built for that. BUT it can be built to do it... and if you do it right.. the 420A can be a great engine and produce really good numbers. Good luck with everything!

thanks a lot, you're very helpful. i have one more question do i need a turbo manifold. and in that one guy's post he said something about a different oil pan?

[Import2nr99]

yes you will need both. The manifold should come with your kit. non turbo cars have headers, and turbo cars have manifolds. I think the kit you're gettin has a t3/t4 hybrid turbo on it and it should come with the applicable manifold. The oil pan will be needed along with oil and water lines for the turbo. Both should be included in your kit or they can be taken off of an old eclipse or bought on ebay. eclipseRST can probably tell you exactly where and what to get. try pming him about it. if it' not included in the kit.

[nicholas9walter]

the turbo offed is a 16g. when you are buying stage 1 and possibly up to three, do you have to buy stage 1 then buy stage 2 then stage three or can i just go straight to stage 3 and fill in a few parts myself? is it way too costly to keep buying kits of hahn. I'd also like to learn what it takes to tune your gas and turbo for it to run properly before i spend this much money on something i don't know how to use.

[EclipseRST]

personally i wouldnt buy a kit from HRC... way too expensive, if i would have gone that way i would have been looking at spending close to 7-8 grand on the kit and everything else i have...and that doesnt include the work i did on the block or head! instead i spent between 4500-5000 on everything including the kit i built myself and i also installed it all myself to which saves a shit load on labor costs, although your car will probably be down for about 3 - 4 weeks its all worth it in the end! my car took a month just cause i had to take the block in and have it cleand, bored + honed, and have the head cleaned, valve guides gone through, valve seats reseated, reassembled and pressure tested, then put everything back together and put it back in the car! the thing that took the longest was taking the block and head in... that took about 2 to 2-1/2 weeks, but it was all worth it!

oh and yes, you were right, i am pushin 350whp (without nitrous) out of my little POS 420a i bet i can get more except i dont want to blow my motor just yet, but i am sure it could handle if i boosted up to 25psi along with the nitrous shot but i dont want to take the chance!

[nicholas9walter]

the hahn guys push 400 no problems and a stage 5 and what should i get if i don't get a hahn racecraft?

[EclipseRST]

yea but the HRC stage 5 kit has 400hp at the crank... plus it doesnt inclued any head upgrades... like valves or anything, then you have do do all the head and block work yourself and it doesnt inclued any controllers... nothing!!! so you spend 6 or 7 grand on a kit that wont even get you very far! its up to you... if you dont by a kit, just start pieceing things together like i did... much cheaper and easier to do!

[nicholas9walter]

i'm not advanced enough on this shit to know what to peice together though.
